數(shù)詞與主謂一致

一、用所給動詞的適當形式填空

1.A teacher of English and class teacher ________ (tell) us something about volunteer workers now.

答案與解析　is telling　句子主語為“英語老師兼班主任”為一個人，故后面的謂語動詞要用第三人稱單數(shù)形式，從now可知，用現(xiàn)在進行時。

2.When and where this took place ________ (be) still unknown.

答案與解析　is　主語為主語從句，雖由and連接但卻指的是同一件事，故謂語動詞用單數(shù)形式，且表示被動，故填is。

3. Every means ________ (try), but none proved successful.

答案與解析　has been tried　means的單復數(shù)同形，從every可知這里是單數(shù)，因此謂語動詞也用單數(shù)，而且根據(jù)句意可知，是“每個辦法都被嘗試過了”，故用被動語態(tài)。

4.Weibo as well as WeChat ________ (serve) as a media platform for people to share their thoughts instantly without limits of place or time.

答案與解析　serves　句意：微博和微信可以作為一個供人們隨時隨地分享他們想法的媒體平臺。serve as表示“可用作，可當……使”。由as well as可知，該句的謂語應由Weibo而定，故應用第三人稱單數(shù)形式serves。

5.—Hey! Here is a message on my cellphone，telling me that I have won the first prize of a weekend for two in Paris.

—Delete it! It's a trick. Many a person ________ (cheat) by such tricks.

答案與解析　has been cheated　句意：——嘿，我手機上有一條短信，告訴我我已獲得巴黎周末雙人游的大獎?！獎h掉吧。那是個騙局。許多人被這樣的短信騙過。“many a＋單數(shù)名詞”做主語，謂語動詞用單數(shù)形式，根據(jù)句意可知，許多人已經(jīng)被騙過，故用現(xiàn)在完成時的被動語態(tài)。

6.One survey shows that large quantities of water ________ (be) wasted every year in China，and that one third is available to be saved.

答案與解析　are　large quantities of＋不可數(shù)名詞/復數(shù)可數(shù)名詞做主語時，謂語動詞常用復數(shù)形式，即由quantities決定，且由every year可知用are。

7.Hank as well as the other children who have no parents ________ (take) good care of in the center.

答案與解析　is being taken　as well as連接主語時，謂語動詞和前面的主語一致，而且take good care of和Hank構成被動關系，故用被動語態(tài)。

8.What the teacher of the science class does and says ________ (be) of great importance to the students at college.

答案與解析　is　句意：理科老師在課堂上說的話和做的事對學院里的學生很重要。本句的主語是主語從句，且主語從句中用了并列謂語，表示的是同一問題的兩個方面，謂語動詞應用單數(shù)形式，且陳述的是客觀情況，應用一般現(xiàn)在時。

9.Children are not recommended to see such films as ________ (be) bad for their mental development.

答案與解析　are　分析句子結構可知，空處是as引導的定語從句并在從句中做主語，先行詞為films，因此使用復數(shù)動詞are。

10.Wasn't it the icy road rather than the drivers that ________ (be) to blame for the series of traffic accidents？

答案與解析　was　此處謂語動詞的單復數(shù)應與被強調的主語一致，而rather than連接主語時，謂語動詞應與前面的名詞the icy road一致，所以使用was。
