1. add作“加，增加”解时，既可作及物动词，又可用作不及物动词；作“又说，补充说”解时，与直接或间接引语连用。如：
If the tea is too strong, add some more hot water． 如果茶太浓了，再加点开水。
After a short while, he added that he would try his best． 过了一会儿，他又接着说他会尽力。
At last mother added he must be more careful next time. 最后母亲又说下次他必须更加小心。
2. add to意为“增添，增加，增进”。如：
The bad weather added to our difficulties． 恶劣的天气增加了我们的困难。
He did nothing but add to our trouble. 他什么也没做，只是增加了我们的麻烦。
3. add up to...“总共达……；加起来达到……”,该短语不用于被动语态。如：
The cost of two trips added up to 1,000 dollars. 两次旅行的费用总计达1000美元。
All his school education added up to no more than one year． 他的学校教育加起来不过一年。
4. add... to...“把……加到……上”, 是把前一项加到后一项之后或之中。 如：
If you want to eat hot things, you can add red pepper to them. 如果你想吃辣的东西，可以加些红辣椒在上面。
Add these to the sandwich. 把这些加在三明治上。
Add two to seven, and you will get nine．七加二等于九。
5. add up "加起来".如:
Add your scores up and you we will see who won.
Please add up all the numbers to see how much they add up to .
