1．The poet and writer are invited to give a speech at the meeting.
2．No one except my parents know it.

3．Your clothes is on the table over there.
4．The number of the students in that school are about one thousand.
5．The class was watching TV when I entered the room.

population 单独作主语谓语动词经常用单数；如果其前有分数或百分数，而且后面又有复数名词时谓语动词用复数。如：One fifth of the Chinese population are workers. 此处把are改为is。

3．A child as he is, he can speak five languages.
用as引导让步状语从句，可把形容词、副词和不带冠词的名词放于as前。所以前半句改为：Child as he is…
