主谓一致

1．The poet and writer are invited to give a speech at the meeting.

poet和writer共用一个冠词，指的是一个人身兼二职，所以谓语动词应为单数。把are改为is.

2．No one except my parents know it.

主语后加except再加上若干数量的名词，谓语动词和主语保持一致。所以把know改为knows。类似的用法的词或短语有：but, besides, with, together with, along with, as well as等等。

3．Your clothes is on the table over there.

clothes为复数句词，谓语动词应为复数。把is改为are。

4．The number of the students in that school are about one thousand.

此名的主语为number而不是students。因此把are 改为is。

5．The class was watching TV when I entered the room.

class作主语时，把它看成一个整体时谓语动词用单数，看成每一个成员的个体行为时谓语动词用复数。一般来说，一些具体行为如看电视、吃饭、洗澡等都属于每一个成员的个体行为。此处把was改为were。

6．The population of our country are increasing slowly now.

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。

倒装

1．No sooner he had reached the station than the train left.

no sooner 为否定副词，放于句首时句子要部分倒装，因此此句应改为：No sooner had he reached the station than the train left.

2．Here comes he.

here 放于句首时，句子主谓要完全倒装，但句子主语为代词时，则主谓不倒装。此句应改为：Here he comes.

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…
