3b
Life can sometimes be difficult for teenagers. Most, however, get through their teenage years with the help of their families and friends. Du Fei and Wang Le are two typical teenagers.
Du Fei is 15 years old. Like many teenagers, he has a few habits that are not so good for him. For example, he listens to very loud music that is bad for his hearing.
On the other hand, he doesn’t eat many snacks —he prefers his mother’s home cooking. But in school he doesn’t pay attention in class, and his parents always tell him to try harder. His parents and teachers want him to change his attitude, and are happy to help him. They know it is never too late to change bad habits.
Wang Le wants to do things that most teenagers do. For her, It’s important to have friends, and to spend time with them. But perhaps she hangs out with them a little too much.
Wang Le likes to eat junk food , and she would rather drink coffee and cola than water. Her parents have asked her to try to eat more healthily, but she doesn’t like to. However, Wang Le’s parents trust her because she tells them her problems. They know she always does her best at school, so they let her organize her own life. She is hardly ever stressed and she laughs a lot.

选择。would rather 无人称变化，其否定形式是在 rather 后加 not，
疑问形式是将would 提到主语前面。 would rather do sth. 意为“宁愿
做某事”，如果表示“与做某事比起来更愿意做某事”，则用 would
rather do sth. than do sth.，该句中 than 后省略了 drink。
※Most teenagers would rather spend time with friends than stay at home.
大多数青少年与待在家相比更喜欢和朋友们共度时光。
6. However, Wang Le’s parents trust her because she
tells them her problems. 然而，王乐的父母相信她，

（2）不定式的时态和语态变化：
时态 主动语态 被动语态
一般时 to do to be done
进行时 to be doing
完成时 to have done to have been done
(1) 作主语
※ To keep our environment clean and tidy is our duty.
保持环境的清洁是我们的职责。

have），四看（see、watch、look at、notice）。
注意:当它们用于被动结构时，to 必须保留（let 除外）。

(3) 在 but、except 等表示“除了……”之意的介词前，若有动词
do 的某种形式，介词后作宾语的不定式常省略 to。
※ He does everything except go to school. 他怎么也不去上学。
so as to 意为“为了”，表目的；“too...to...”意为“太……而不能……”，表结果。
