be allowed to do 和allow doing 区别
allow doing 允许做某事
没有 allow to do这种用法,但被动语态中可用: sb be allowed to do sth 。
所以谈不上区别。
注:
allow 的用法:
allow doing sth. 允许做某事
allow sb to do sth . 允许某人做某事
sb be allowed to do sth 被允许做某事
如
1). It's not allow smoking in this meeting room.
这间会议室里是不允许吸烟的。
2). His parents allow him to watch TV half an hour every day .
他父母亲允许他每天看半小时电视。
3). Students aren't allowed to smoke .
学生不许吸烟。
注:不能说“Students don't allow to smoke ."
allow doing. sth. 允许做某事。
allow sb. to do sth. 允许某人做某事。
1、 在主动语态中,如果allow后面没有sb出现在allow后面的话,就要接动名词形式;如果后面有sb做宾语,则必须要接to do sth.
2、在被动语态中,只有be allowed to do sth的句式结构,而没有sb be allowed doing sth。
即:
1)allow sb to do sth,allow后有人(宾语)时,用不定式,意思是允许某人做某事,如The teacher allowed us to discuss in class yesterday.
2)allow doing sth,allow后没有人(宾语)时,用动词ing形式,意思是允许做某事,如The teacher allowed discussing in class yesterday.没说允许谁做,所以用动词ing形式.
3)一般不用allow to do sth这种形式。
拓展资料例句:
我不许你干那样的事。
My father won't allow me to take the wheel.
父亲不让我驾驶汽车。
Our teacher does not allow cheating to go unpunished.
我们的老师不容许欺骗行为不受到惩罚。
具有类似用法的动词还有:
forbid sb to do sth / forbid doing sth
advise sb to do sth / advise doing sth
be allowed to do 是被动语态 某人被允许做某事。allow doing 是主动语态 允许某人做某事。举个例子,比如说:Tom is allowed to play computer games. 汤姆被允许可以玩电脑游戏 Tom’s father allows Tom playing computer games.汤姆的爸爸允许汤姆可以看电视。 不知道这样说 您明白没有 明白的话就请 呵呵~ 采纳一下
be allowed to do 被允许做某事,allow doing 允许做某事。一个表被动,一个表主动。
