Units 1-7 重点回顾（一）
作者：李国
1. You don't have much money. Why don't you make him a card?
much用来修饰不可数名词，many用来修饰可数名词。Why don't you + 动词原形？＝ why not + 动词原形？意为“为什么不……？”这是提建议的常用句型之一。除此之外，还可用：① What / How about + 名词/代词/ V-ing? 如：How about spending the weekend with us? ② Would you like + 名词/代词/动词不定式？如：Would you like to learn French? ③ Would you please + 动词原形？如：Would you please turn off the radio?
2. What are we going to do?
一般将来时可由“be going to + 动词原形”构成，表示将要发生的事或打算、计划、决定要做的事。一般将来时还可由“助动词will / shall + 动词原形”构成。此外，表示位移的动词（如：go, come, leave等），常用现在进行时表示将来。
3. I think this one is bigger and cheaper than that one.
形容词、副词的比较级前面一般不用the，但是遇到下列情况时，常用the：①表示“两者中比较……的一个”，通常用“the + 比较级 + of the two”这一结构。如：Tom is the stronger of the two boys. ②表示“越……越……”用“the + 比较级，the + 比较级”这一结构。如：The more you learn, the happier you are.
形容词的最高级前一般要用the, 但以下情况不用the：①形容词的最高级前已经有物主代词、名词的所有格等修饰语时。如：She is my best friend. ②两个形容词的最高级同时修饰一个名词时，后一最高级前常常省略the。如：This mooncake is the biggest and nicest of all.
