高频易错点04 祈使句 Look at... 的用法
• 例句:
Look at the panda! It's cute.
Don't look at the lion. It's dangerous.
易错点提示
1.Look at 后接名词或代词宾格,不能直接接形容词(如 “看那只可爱的老虎” 要说 Look at that cute tiger. 不能说 Look at cute.);
2.否定形式在 Look 前加 Don't,即 Don't look at...;
3.注意区分 Look(单独使用,引起注意)和 Look at(后接宾语,强调看的对象)。
小练笔
( )1. ______ at the elephants. They're big.
A. Look B. See C. Watch D. Read

A. look B. sees C. watches D. reads
3. Look at ______ (he). He is my friend.
4. Look at ______ (this) tigers. They're strong.
5. 不要看那只鸵鸟。(翻译句子)
______ ______ ______ that ostrich.
点拨
1. A look at 是固定搭配,“看……”,see 强调看到的结果,watch 强调持续观看,read 指阅读,故选 A。
2. A don't 后接动词原形,look at 是固定搭配,故选 A。
3.him look at 后接代词宾格,he 的宾格是 him。
4.these tigers 是复数,this 变 these。
5.Don't look at 否定祈使句用 Don't + 动词原形,look at 后接宾语 that ostrich。
