一、用所给动词的适当形式填空
1．A teacher of English and class teacher         (tell) us something about volunteer workers now.

2．When and where this took place         (be) still unknown.
答案　is
解析　主语为主语从句，虽由and连接但却指的是同一件事，故谓语动词用单数形式，且表示被动，故填is。
3. Every means         (try), but none proved successful.

解析　means的单复数同形，从every可知这里是单数，因此谓语动词也用单数，而且根据句意可知，是“每个办法都被尝试过了”，故用被动语态。
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　serves

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

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

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

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

解析　分析句子结构可知，空处是as引导的定语从句并在从句中做主语，先行词为films，因此使用复数动词are。   
10．Wasn't it the icy road rather than the drivers that         (be) to blame for the series of traffic accidents?
