从新宫到鸟巢:帮我看看这几题怎么做，最好说明原因,3ks

1.D
had better not do

2.B
lest后面虚拟语气用(should)+动词原型，表示消极

3.A
在表达否定或者疑问意义的句子中，dare为情态动词，用dare+动词原型

D1,You_________to bed early if you really want to see the football match on TV.
A.may not as well as go B.had not better C.might not as well go D.had better not go
had better not to do是最好不要做某事
B2,I’ll be kind to her lest she_____to leave me.
A.decides B.decide C.will decide D.decided
lest后带虚拟语气,动词用原形

C3,It was so dark outside that nobody ___out
A.dare go B.dared go C.dare to go D.dares to go
dare to敢去做某事,又因为它是情态动词,没有时态

1,D
had better ont do sth"最好别做某事"
2,A
条件状语从句的条件部分用现在时
3,B
这里dare是普通动词的用法,dare do sth.

1.d
had better not do固定词组，你最好不要去做

2.b
lest后面要用虚拟，表示以防万一
应该是lest she (should) decide to leave me ,should 省略后就变成了原形

3.b
dare作情态动词，dare do sth只用于否定，疑问，条件句中
dare作实意动词，dare (to) do sth ,to可以省略
题中应该用过去时，所以选b，看作情态或实意动词都可以

1. D
根据题意：你真地想看电视上的足球赛的话，你最好不要那么早就睡。
所以： 用had better do 这个词组，且 had better do 的否定形式为 had better no do
综上所述： 用 had better not go
2. A
根据提议：我会友善地对待她以免她决定弃我而去。[lest 为“以免”的意思]
且：lest 后跟动词原形[lest sb do sth]
所以：用 decide
3. D
根据题意：外面天太黑了，没人敢外出。
所以： 用词组dare to do
且; dare 前为 nobody
所以：动词dare 要用 第三人称单数形式 dares

D had better do sth./not do sth. 最好干或者不干某事
B Lest很特殊 lest + 动词原型 以免干什么 虚拟语气 类似的还有苏suggest 暗示做什么
B dare do sth. 害怕，不敢做某事 dare sb. to do sth.挑衅，挑起做某事
