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

5，关于something的用法

1 作主语时谓语动词要用第三人称单数,如：Something is wrong with his bike.2 形容词修饰它时要放在它的后面,如：I have something important to tell you.3 一般用于肯定句中,但也可用于征求意见并希望得到肯定回答的疑问句中,如：There is something wrong with it.Would you like something to eat?

前一句非正式，中式英语，可以用。但后一句更为口语化，已经成为习惯用语。英语学习的话，使用后一句避免出错。 “用后置定语来修饰something”这种说法是不准确的，实际上，当遇到something时，人们往往习惯把“to do”句式放在something的后面，这是一种习惯。同样，问句形式的两句子也是一样的道理。
