Book 3 Unit 2 重点短语讲解1. In this way they cut down the fat and increased the fibre in the meal. (P15)【归纳】cut down削减，减少，砍倒。

【延伸】cut in插嘴；cut off切掉，隔绝；cut up切碎；cut across 抄近路穿过。

【易错点】注意cut down后面介词的使用，如果表示“削减，减少”时，后面可以跟介词on；如果表示“使……降低到”时，用to；如果表示“使……降低了”时，用by。

如：The doctor told my husband to cut down on smoking. 医生嘱咐我丈夫少吸烟。

You can cut the book down to 200 pages. 你可以把这本书减到200页。

2. It cost more than a good meal in his restaurant!(P10)【归纳】1. “more than ＋数词”意为“……以上”，如：I have known David for more than 20 years.2. “more than ＋名词”表示“不仅仅”，如：Jason is more than a lecturer; he is a writer, too.3. “more than ＋形容词/ 副词”意为“非常”，如：I am more than glad to help you.【延伸】rather than而不是；other than除了；less than很少，不到。

【易错点】no more than意为“只有，仅仅，不过（= only; just ）”，强调“少”；not more than意为“至多，顶多，不超过”，其意义与at(the) most 相同。

3. Their balanced diets became such a success that before long Wang Peng became slimmer and Yang Hui put on more weight. (P15)【归纳】before long不久以后，很快。

高中英语学习材料***鼎尚图文理制作***Unit 2 Healthy Eating语法探究1. must 的主要用法。

⑴表示必须、必要We must do everything step by step .我们必须按部就班地做一切事情。

⑵must be + 表语的结构，通常表示猜测，含有“一定”之意。

（只用在肯定句中）He must be an honest boy. 他一定是个诚实的男孩。

must +have +过去分词的结构，常用在肯定句中，表示对过去发生行为的推测，含有“一定”、“准是”的意思。

否定和疑问句用can。

She must have studied English before.她以前一定学过英语。

⑶must 的否定式有两个：当回答由must引起的问题时，否定答复要用needn’t或don’t have to表示“不必”、“无须”、“用不着”、“不一定”的意义。

当表示“不应该”、“不许可”、“禁止”时，就用must not。

Must I go tomorrow? 明天我必须去吗？Yes, please.是的，请吧！No , you needn’t. 不，你不必去。

2. have to 的主要用法⑴have to 有人称和数的变化，可用于多种时态中：一般现在时中当主语是第三人称单数时要用has to，其余的人称用have to，一般过去时中要用had to；一般将来时中则要用will have to.She has to go to school by bus. 她不得不乘公共汽车上学。

You'll have to see the doctor if you get ill. 如果你生病了，就得去看医生。

⑵have to 的否定句和疑问句的构成往往要借助于助动词do的适当形式或助动词will即have to, has to, had to和will have to的否定式分别为don't have to, doesn't have to, didn't have to 和won't have to，疑问句是在句首加助动词do的相应形式，句中还原成have to或把will放到句首。
