主謂一致

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

poet和writer共用一個冠詞，指的是一個人身兼二職，所以謂語動詞應為單數。把are改為is.

2．No one except my parents know it.

主語后加except再加上若干數量的名詞，謂語動詞和主語保持一致。所以把know改為knows。類似的用法的詞或短語有：but, besides, with, together with, along with, as well as等等。

3．Your clothes is on the table over there.

clothes為復數句詞，謂語動詞應為復數。把is改為are。

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

此名的主語為number而不是students。因此把are 改為is。

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

class作主語時，把它看成一個整體時謂語動詞用單數，看成每一個成員的個體行為時謂語動詞用復數。一般來說，一些具體行為如看電視、吃飯、洗澡等都屬于每一個成員的個體行為。此處把was改為were。

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

population 單獨作主語謂語動詞經常用單數；如果其前有分數或百分數，而且后面又有復數名詞時謂語動詞用復數。如：One fifth of the Chinese population are workers. 此處把are改為is。

倒裝

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

no sooner 為否定副詞，放于句首時句子要部分倒裝，因此此句應改為：No sooner had he reached the station than the train left.

2．Here comes he.

here 放于句首時，句子主謂要完全倒裝，但句子主語為代詞時，則主謂不倒裝。此句應改為：Here he comes.

3．A child as he is, he can speak five languages.

用as引導讓步狀語從句，可把形容詞、副詞和不帶冠詞的名詞放于as前。所以前半句改為：Child as he is…
