doing
allow，permit，advise，forbid
有这样几道题：
a. We don’t allow __________ in the office. b. We don’t allow people __________ in the office. c. People are not allowed __________ in the office. A. smoking B. to smoke C. smoked D. smoke
此题答案为a句选 A，b句和c句均选 B。一般说来，动词allow(允许)之后应接动名词作宾语，但是若其后接有名词或代词作宾语，则其宾语后的补足语应用不定式，而不是动名词(注意：c句与b句同义，只是c句为b句的被动形式)。
类似以上用法的动词还有 permit，advise，forbid等： 1. a. We don’t permit _________ on the grass. b. We don’t permit people _________ on the grass. c. People are not permitted _________ on the grass. A. walk B. to walk C. walking D. walked
2. a. He advised _________ early. b. He advised us _________ early. c. We were advised _________ early.
A. leave B. to leave C. leaving D. left
3. a. We forbid __________ a noise. b. We forbid people __________ a noise. c. People are forbidden __________ a noise.
A. make B. to make C. making D. made
sb to do
但动名词前用所有格或物主代词作逻辑主语是可能的： 4. a. He forbids me _________ with them. b. He forbids my _________ with them.
A. to go B. going C. go D. went 答案：
1. C，B，B 2. C，B，B 3. C，B，B 4. A，B
