第四講 一致

　　一、主謂一致(Agreement of Subject and Verb)

　　1)謂語動詞在人稱和數上必須與主語一致

　　a) 在語序正常的句子中

　　My father has travelled widely.

　　Things are invented when the need is great enough.

　　b) 在there be結構中

　　There is no smoke without fire.

　　There were not many influential guests at the party.

　　There seems to be little time left.

　　There seem to be too many men in the field.

　　注：在there, here引起的結構中，如主語有好幾個，則謂語動詞可與最鄰近的主語取得一致。例如：

　　There was a TV set, a portrait and several albums(相冊)on the shelf.

　　Here are a few envelopes, a pen and some paper in the drawer.

　　c) 在倒裝結構中

　　In every province of China are found rich natural resources.

　　Here come the five noisy children from next door.

　　d) 在主語后有修飾語的句子中

　　Differences in speech often cause people to snigger(竊笑).

　　His attempt to improve the experiments is successful.

　　A person who has good friends enjoys life more.

　　e) 在主語后有“as well as, not to mention, along with等+名詞”句子中

　　Unemployment as well as taxes influences votes.

　　Taxes, not to mention unemployment, influence votes.

　　This man along with his sons always catches the largest fish.

　　由上述d)、e)諸例可以看出，主謂一致不受修飾語或“as well as等+名詞”結構中名詞的數的影響。此外，主語后若跟有accompanied by, as much as, besides, except(but), in addition to, including, instead of, no less than, rather than, together with等+名詞，也不影響其與謂語動詞的一致關系。

　　2) 單數主語

　　a) 不定式短語、動詞-ing形式(短語)及名詞從句作主語時，謂語動詞用單數。

　　例如：

　　To become doctors is their ambition.

　　Reading without comprehension is no good.

　　What that country needs is more jobs and lower taxes.

　　b) 事件、國名、機構名稱、書及其他作品的名稱用作主語時，謂語動詞用單數。

　　例如：

　　The United Nations was formed in l945.

　　The Thirty-Nine Steps was written by John Buchan.

　　c) 下列不定代詞或限定詞作主語或修飾主語時，謂語動詞永遠是單數。例如：
