英语 ENGLISH (26 13:26:50)He often tells us that he doesn’t ____ in his room.A．promise drinking         B．permit drinkingC．allow to drink         D．let drinking

答案是b。
理由是a意思不对，c的结构应为allow sb to do sth.
d没有这种说法
三个答案排除后就选择b了

B。不被允许在房间里喝酒，是被动。
1）A意思上就不对，promise 是承诺做什么什么
2）C意思上对，语法错，前面是doesn't 后面怎么可以再用动词？
3）错误同C

He often tells us that he doesn’t ____ in his room.---他经常跟我们说他不允许别人在他房间喝酒。
promise drinking ---承诺喝酒。 permit drinking 允许喝酒
allow to drink --允许喝酒 let drinking ---let后面加动词原形。
到底是B还是C对呢？如果C是allow drinking肯定是对的，除非现在他省略了宾语us，即allow(us)to drink。由此可见，只能选B了。
经典例题： I don’t allow _____ in my drawing-room.I don’t allow my family _____ at all.
A. to smoke; smoking
B. smoking; to smoke
C. to smoke; to smoke
D. smoking; smoking
这个例题的答案选B。 allow doing sth 和 allow sb to do

B
他经常告诉我们他不允许在他的房间里喝酒。
permit doing 允许做某事
allow sb to do sth.
allow doing 允许某人做某事
promise to do 同意做某事
let do 让 做某事

显而易见...B

A是许诺 B是允许

B．permit drinking为正确表达.这里的drinking已演化为名词,做及物动词permit的宾语,是permit sth 的短语.A．promise drinking（没有这种表达）C．allow to drink （allow只用于allow sb sth 或allow sb to do sth ...

选B. promise to do
let sb. do allow sb to do permit doing
