You can't walk into the office without Rihanna's voice singing “work work work work work work” in your head.And that one line from Lady Gaga's
Bad Romance still makes you want to scream.These are commonly known as earworm songs—those sticky tunes that continue to play in your head.A recent study finds that more than 90% of adults report hearing earworm songs on a weekly basis.
Fortunately，most people report earworm songs as pleasant.But others find them annoying or even maddening.“Some people are troubled by them to the point that it disturbs life，” says Elizabeth Hellmuth Margulis，a professor at the University of Arkansas who has studied earworm songs.
Margulis says earworm songs tend to have some predictable characteristics.For one thing，they tend to small parts of a song—not the whole track.And “the songs you've heard recently also have the most possibility to get stuck in your memory，” she says.
But sometimes something strange and unpredictable can also start a track paying in your head.“Once I was at the doctor's office and saw a poster of a man who I thought looked like Gaston—a character from Beauty
and the Beast，” Margulis recalls.A couple minutes passed，and she realized she couldn't get Be Our Guest，the song in the movie，out of her head，even though she hadn't thought of the tune in years.In that instance，she was able to identify her earworm's trigger：the Gastonlooking man in the poster.“But the connections can be really unclear，” she says.
Margulis points out that，in all of human history，recorded music is a very new phenomenon.She says some have inferred that earworm songs are also new—the unintended consequence of being able to hear the same song played everywhere in the same way over and over again.So far，the convincing
explanation for why human beings experience earworm songs remains a mystery.But there are some wellestablished ways to cast off the earworm songs.
“Finding a mentally demanding task and putting your mind on it usually shifts attention away from internal music.People tend to get earworms when performing tasks that don't require their full attention—stuff like doing the dishes，” Margulis says.
Chewing gum can also help.When a song is stuck in our heads，it's almost like we're singing along with it.If you make your mouth do something else—chewing gum，eating a meal or talking with a friend—that can kick out the earworm.
You could also face your enemy.By listening to the full track that includes the passage stuck in your head，you may find “closure” and relief.

While there are a few ways to make use of your old smartphone，one of the better ways is to convert into a dash cam (行车记录仪) that you can use on your bicycle.With the camera，you can record your rides，which is especially helpful if you are involved in a crash with another vehicle.
To use your smartphone as a dash cam on your bike，you will need to make sure it is properly secured to your bike.To do this correctly，you must take two strips of heavyduty Velcro (a kind of cloth used as fastening) along with two pipe clamps (管夹) and a flat corner brace (角撑) to properly attach it.You will start by attaching the corner brace to your smartphone.
Next，attach a Velcro strip to your phoned back.You will put the second strip on the end of the brace corner and cut any extra Velcro off and away from the brace.By using heavyduty Velcro，you shouldn't have to worry about the camera brace must be attached to the bicycle directly.
Take two pipe clamps so you can attach the part of the corner brace so the phone can be held up and used.The pipe clamps must be positioned near the center of the handlebar，which will enable you to get a better picture when videotaping.
To run a dash camp app on your old phone，you will just need to download a dash cam app onto the old phone.You will then just start the app at any time you head out on the road.There is always the chance of flaws，but you will be giving yourself a way to protect yourself in a friendly，ecofriendly manner that is much less expensive than purchasing a dash cam.

A Japanese company，Next Technology，has created a robot dog that can tell you how bad your feet smell，by using a powerful sensor fixed in its nose.If your feet don't have a bad smell，Hanachan will happily wag its tail，if it's exposed to feet that are mildly smelly，it'll start to bark，and if they give off an extremely bad smell，it'll just fall over like the smell caused it to faint(昏倒)．
Foot odor (脚臭) is a big deal in Japan，where it's a custom for people to take off their shoes whenever they enter someone's home.In fact，exposing others to bodily odors can be considered annoyance in Japan.Some of the most brilliant minds in the country's tech industry have been trying to solve this problem.Last year，Thanko started selling armpit (腋窝) fans designed to keep people's armpits nice and dry.Now，we have Hanachan.
The robot dog has a special sensor for a nose，and can tell you if your feet smell just by sniffing them for a few seconds.According to some media reports，Hanachan can help solve the problem of extremely smelly feet by spraying them with air freshener，but it's unclear whether this feature
comes builtin，or if you'll have to pay extra for it.
According to researchers at Next Technology，the idea for Hanachan was inspired by a person who desperately wanted some way to know if his feet smelled.“He told us his daughter had said his feet were smelly，” Next Technology's Kimika Tsuji said.“But he didn't want to know how bad the odor was because he would feel hurt.That's why we developed this cute robot.”
You may be able to make Hanachan faint with your smelly feet，but it can have the same effect on budgetconscious people.Next Technology plans to start selling the feetsmelling robot dog for ￥100，000 ($9，280) next May.
28．Under what condition will Hanachan bark? A．When its nose is fixed with a sensor. B．When it wags its tail.
C．When it detects mildly smelly feet. D．When something is wrong with its nose.
29．Why is foot odor paid great attention to in Japan? A．Because Japanese have strong bodily odors.
B．Because Japanese are usually barefooted at others' home. C．Because Japanese are especially considerate of others. D．Because its tech industry is highly developed. 30．What can be inferred about Hanachan from the text? A．It has a builtin air freshener sprayer. B．It's already available in the market. C．Its idea comes from Kimika Tsuji. D．It can recognize foot odor quickly.
31．What does the underlined part in the last paragraph imply? A．Hanachan is no cheap thing.
B．People should mind their smelly feet.
C．People should be careful about their budget. D．Hanachan makes people loosen their budget.

China's Singles Day，which falls on Nov.11 every year，has far surpassed its U．S.counterparts of Black Friday and Cyber Monday—combined.Last year，Americans spent a record $12.8 billion online between Thanksgiving Day and Cyber Monday.It's impressive until you compare it to the $17.6 billion in sales made by Chinese consumers in a single 24hour period during 2016's
Singles Day.
Singles Day is known as “Bare Sticks Day” or “Bare Branches Day” in Chinese—because the date “11/11” looks like bare branches and “one” is the loneliest number.Singles Day began in the early 1990s in the dorm rooms of Nanjing University when a group of single friends were sorry about the lack of significant others and decided to mark the day by organizing activities as a group of singles and reducing their loneliness by buying themselves a gift.
Then in 2009，sensing a break between the sales period of China's National Day on Oct.1 and Chinese New Year in late January or early February，Alibaba's Jack Ma saw an opening：sell to comfort lonely hearts.
The first year did only $7.5 million in sales，but just 8 years later，shoppers spent $25.3 billion，or 168.2 billion yuan，this year—a 40 percent jump from last year's $17.6 billion.For comparison，Black Friday and Cyber Monday in the U．S.only netted $6.79 billion in 2016.Amazon doesn't release sales figures for July's Prime Day，but it's pretty safe to believe the notquitenationalholiday doesn't come close to $25 billion.
“More than $25 billion in one day is not just a sales figure，” Alibaba Group CEO Daniel Zhang said in a statement.“It represents the desire for quality consumption of the Chinese consumer，and it reflects how merchants and consumers alike have now fully accepted the combination of online and offline sales.”
32．What does the underlined word “others” refer to in Paragraph 2? A．Roommates. B．Good friends.
C．Boyfriends or girlfriends. D．Relatives.
33．What is the original purpose of China's Singles Day? A．To promote the online sale of goods.
B．To reduce loneliness of singles in China. C．To create a holiday for all Chinese youth. D．To find boyfriends or girlfriends for singles.
34．China's Singles Day became consumers' day in ． A．the early 1990s C．2017
B．2016 D．2009
35．Which of the following words can describe Daniel Zhang's attitude to online sales?
A．Optimistic. C．Worried.
B．Indifferent. D．Confused.

I was in a taxi in Singapore last week and I couldn't help but notice the sticker attached to the back of the driver's seat. In English and Chinese it read，“We accept Alipay.” It was a reminder that ecommerce in China is no longer just about how great brands break into the Chinese market. It's also about an important slice of China's economy coming to you.
If you are a brand manager or a salesman，you're increasingly likely
to find yourself fighting with the push of Chinese ecommerce companies in your home market. That's for two reasons：China's leadership in electronic payments and the continued rise in Chinese tourism. The result of this is that Chinese consumers are an increasingly important factor in markets around the world.
On the electronic payment front，there are some strong reasons to introduce the electronic payment systems Chinese consumers are already using. In China，the traditional wallet has been replaced by an electronic wallet on a smartphone. It's common to make all of your payments for daily needs through that smartphone，using one of the two main electronic payment providers：WeChat Pay or Alipay.
It's not just easy to use. These two tech companies have the reach and customer base to push their payment systems beyond their original ecommerce mission. Noodle shops will take electronic payments，and even street musicians have QR for donations. Whether you are paying your electricity bill or seeing a doctor，your mobile phone can handle the payment.
As a result，China is today the most cashfree of any of the world's major economies—and that trend will continue. Already，the numbers are staggering．According to a survey by Ipsos and Tencent，14% of Chinese people do not carry any cash，while 26% hold less than RMB100 (less than $16) in their wallets，day to day. According to consulting firm iResearch. In 2016 China's mobile payments hit $5.5 trillion，almost 50 times America's $112 billion.
28．The writer tells his experience in a taxi in Singapore to ． A．introduce the topic of the text B．examine a problem in detail C．offer some solutions to an issue D．inform the finding of a new study
29．The fact that Alipay is accepted overseas indicates that ． A．mobile payment in China is becoming more and more popular B．Chinese economy is taking up a bigger share internationally C．great brands find it harder to enter the Chinese market D．the world market is determined by Chinese tourists 30．The aim of Paragraphs 34 is to ． A．warn the cost and safety of cashfree payment
B．explain the reasons for the popularity of electronic payment C．prove the common usage of mobile payment with numbers D．introduce the two main digital payment providers
31．Which can best replace the underlined word “staggering” in the last paragraph?
A．Worrying. C．Ridiculous.

As the saying goes, man struggles upward； water flows downward. Water runs downhill from mountaintops to streams, rivers, and oceans. But it
B．Important. D．Impressive.
isn’t the only way that water moves. A new study measures how water travels from country to country for human consumption. This flow isn’t the type we usually think about. These scientists looked at the water used to grow and make the products which get shipped from nation to nation as imports or exports. They call this a flow of “virtual water(虚拟水)”.
We typically think about water as the liquid that flows from a tap. However, 92％of the water used by people goes into growing crops, according to water researcher Arjen Hoekstra. He recently studied the hidden travels of virtual water used in products made from things like crops and meats. These products are shipped around the world.
For example, consider a sugary soft drink. Hoekstra estimated that to produce one half-liter of the drink requires between 170 and 310 liters of the water—about 95％ is used to grow and process the ingredients(原料). Another 4％goes into the packaging and labeling. In Hoekstra’s calculation, when one country produces a half-liter of soda and sells it abroad, the virtual water it exports would fill a large refrigerator.
According to Hoekstra’s new report, dry countries like Israel and Kuwait, both in the Middle East, get the majority of their virtual water from other countries, through imported products. More surprisingly, some wetter countries, like the Netherlands and the United Kingdom, also get the majority of their virtual water from other places. That means that most of the water used to grow or produce the products and food consumed in those countries came from other countries. In the United States most of the virtual water used comes from American sources. In China even less of the water is associated with its products.
1.The example of a sugary soft drink in Paragraph 3 is given to show ______. A.how drinks are shipped B.how virtual water is exported C.how virtual water is used
D.how drinks are made
2.In which countries does most part of virtual water come from outside? A.Kuwait and the Netherlands. B.China and the United Kingdom. C.America and the Netherlands. D.Israel and America.
3.What is the best title for the passage? A.Crops and Virtual Water B.Water’s Worldwide Travels C.Benefits of Virtual Water D.Import and Export of Water
4.The passage is most probably from a ______. A.science news report B.science fiction story C.newspaper advertisement D.book review

With the popularity of 3D movies over the past several years , there was no doubt that the technology would make its way into our homes, The question is: Is it really a technology that is going to stay with us , thus deserving an upgrade(升级) at this time?
Many families have recently bought a new TV set, and the idea of changing it just to take advantage of a technology in its infancy(初期)will put many people off the idea. Then there are the additional costs that come along with a 3Dset from needing to get a Blu-ray player that can process the signal to purchasing enough glasses for the entire family to be able to watch a program at the same time.
Another issue is that the glasses are expensive as well as complicated, and have also been known to cause headaches, none of which makes for a pleasant experience. While manufacturers are working towards glasses-free technology, it just isn’t here yet, and it could be several years before it is commercially successful. That is one of main things that will keep 3D completely in the “fashion” zone for the time being . If the television manufacturers are willing to hold onto the idea until glasses-free choices are available—and they can reach a higher installed user base—this might very well catch on. Everyone needs to remember, however, that these are businesses, and they are in it to make money. If 3D isn’t selling at the rate they are comfortable with, then they will dump it and move on to the next thing. Many homes are filled with products that didn’t catch on rapidly and companies ended up leaving them with no support. Do you have an HD DVD player? Remember how the MiniDisc was supposed to replace the CD? For now, it’s easy to see how 3D televisions could join this list of technologies. There is one upside to the 3D television problem: They have beautiful 2D images. Even if 3D goes away, you still have a great –looking screen and beautiful images. If you are in the market for a new TV and you can afford to drop the couple extra hundred dollars to buy one, you can view it as guaranteeing your purchase in case the technology proves to be effective.
51.We know from the text that 3D TV .
A. is easy to operate B. has been fully developed C. has many products attached to it D. has already replaced normal TV sets
52.What’s the main idea of paragraph 4? A.3D is fashionable and expensive.
B .It’s hard for 3D to be commercially successful.
C. Television manufacturers’ only purpose is to make money.
D. It’s impossible to create glasses-free technology at the moment. 53.The examples of the HD DVD player and CD are to show .
A. they are not necessary B. they are bound to be replaced
C.3D TV might not be here to stay D.3D technology needs improving 54.What’s the author’s opinion on 3D TV?
A. He is critical of it. B. He thinks highly of it. C.It is more effective than expected. D. It has more beautiful images than 2D. 51-54.CDCA [九]
The world's largest solar thermal plant(太阳热能发电站)is set to begin producing power in the United States by the end of the year. Wind and energy from the sun are generally considered clean, unlike energy from coal-burning power stations. However, environmentalists now worry that too much solar power development could harm the local environment.
A California company — BrightSource Energy is building a huge solar power plant in the Mojave desert, about 60 kilometers southwest of Las Vegas, Nevada. The plant is known as the Ivanpah Solar Electric Generating System. Joe Desmond works for the company. \"This is actually one of the highest concentrations of sunlight in the world, out here in Ivanpah.\" explained Desmond. BrightSource Energy will deploy 170,000 specially designed mirrors to direct solar energy towards boilers on top of three power towers. The steam produced in the boilers will drive turbine (涡轮) to make electricity. Joe Desmond says the steam can reach temperatures of more than 260 degrees Celsius. \"We can store the sun's thermal energy in the form of molten salt, so we can produce electricity even when the sun goes down. There is a lot of interest in concentrating solar power around the globe in environments where you have lots of sun, such as China, South Africa, the Middle East, North Africa, explained Desmond.
Environmentalists generally support the idea of solar power, however, many are concerned about the effect of power plants on sensitive environment. Lisa Belenky is a lawyer with the Center for Biological Diversity, a private group. She says environmentalists are specifically worried about the effect of the Ivanpah Solar Project on the sensitive plant and animal life in that part of Mojave desert. \"Even though the desert seems big, when you start cutting it up, it can really affect how the species and the animals and the plants are able to survive in the long run,\"said Lisa Belenky. BrightSource Energy has already spent more than $ 50 million to move endangered desert tortoises away from the power plant. but Lisa Belenky says this is not the answer. \"We should be reusing areas that have a1ready been disturbed, like old mining sites, for example...either on homes, on businesses, parking lots.\" said Belenky.
There have also been reports of birds dying at the Ivanpah Plant and others like it.
Some birds die after colliding with solar equipment which the animals
mistake for water. Other birds were killed or suffered burns after flying through the intense heat at the solar thermal plant. As solar projects increase, environmentalists and developers are considering what to do to reduce bird death.
63. Why is the Ivanpah Solar Electric Generating System being built in the desert?
A. Because the temperature is extremely high in the desert. B. Because there is no life in the desert. C. Because there is much salt in the desert.
D. Because sunlight is highly focused in the desert.
64. Why can the plant make electricity at night?
A. Because the sun's thermal energy can be stored in the form of steam. B. Because the sun's thermal energy can be stored in the form of molten salt.
C. Because the sun's thermal energy can be stored through mirrors D. Because the sun's thermal energy can be stored in the boilers.
65. According to Lisa Belenky, in order to reduce the effect,_____. A. we should move all the plants and animals away from the solar plant B. we should guide the bird not to hit the solar plant C we should build the solar plant in disturbed areas D. we should build the solar plant in the desert
66. The author’s attitude towards the solar projects is _____. A. supportive B. critical C. indifferent D. cautious 63-66DBCD [十]
It's cold and dark outside，and your bed is so warm and comfortable.Going for a run seems like such a bad idea.But before you hide your running shoes，it might be worth giving that crazy idea a go.
According to The Huffington Post，an outdoor run in winter，as opposed to one on a treadmill(跑步机)，burns more calories because the body is working hard to regulate(调节) its core temperature.Furthermore，research shows that race times are faster in cold weather than in warmer temperatures－and quicker runs burn more calories.Similarly，cold weather also makes the heart work harder to distribute blood through the body，making that
vital muscle even stronger.
Outdoor exercise also turns up your energy and rids you of the stress and depression that build up every day.The heat and humidity in the summer can drag you down and tire you faster，but cold weather is refreshing.It adjusts you to your surroundings，making you feel alive.
Of course，the threat of smog in some builtup areas is a further hurdle to winter exercise.Heart attacks，stoke，lung cancer and asthma are all dangers of running in smog.The combination of air pollution and exercise increases the potential problems.If you do choose to run outside on smoggy days，take a path in a park or residential area to avoid car exhaust(尾气)，and go early in the morning，before rush hour.But staying inside on smoggy days and waiting for the next clear day to run is best.
