5．(2009年海南模拟)There are 30 people________in the traffic accident but the injured________rescued at once.

A．injure；were 　　　　　　　B．injuring；was

C．injure；was　 　　　　　　　D．injured；were

解析：选D。injured in the traffic accident作定语修饰people，the injured意为“伤者”，在句中作主语，谓语动词用复数。

4．He will give us a report on how to study English well，but when and where________.

A．is still unknown 　　　　　　B．hasn’t decided

C．is known 　　　　　　　　　D．haven’t been decided

解析：选A。本题考查who，which，what，when，where等引导的从句作主语或单独引导疑问句时谓语动词用单数，排除D。C项不符合句意，B项应用被动形式，所以选A。

3．The number of the cellphones they produced this year ________increased by 30% compared to________of last year.

A．has；that　 　　　　　　　　B．has；those

C．have；those　 　　　　　　　D．have；that

解析：选A。考查主谓一致。the number of+名词复数，谓语动词用单数。that代指上文中的“the number”。

2．Professor Smith，along with his assistants，________on the project day and night to meet the deadline.

A．work　 　　　　　　　　　　B．working

C．is working 　　　　　　　　D．are working

解析：选C。考查主谓一致。如果主语是单数，尽管后面跟有as well as，together with，but，except，like等引导的名词，谓语动词仍然用单数形式。

本单元语法--主谓一致

1．A poet and artist________coming to speak to us about Chinese literature and painting tomorrow afternoon.

A．is　 　　　　　　　　　　　　B．are

C．was　 　　　　　　　　　　　D．were

解析：选A。考查主谓一致及时态。a poet and artist只用了一个冠词，表明是同一个人，所以用单数谓语动词。再结合后面的tomorrow afternoon可排除C项。

4．Try to spend your time just on the things you find ________.

A．worth doing them　 B．worth being done

C．worthy of doing them　 D．worthy of being done

解析：选D。句意：尽量把时间用在你觉得值得做的事情上。worthy作宾补，后接of being done形式，表示与宾语things是被动关系。

3．-This book by Tony Garrison is of great use for our course.

-But I think this latest one is ________ worth reading.

A．better 　　　　　　　　　　　B．more

C．most 　　　　　　　　　　　D．very

1．Is it ________ sparing time for your hobby while your classmates are concentrating on their lessons?

A．worth　 　　　　　　　　　B．worthy

C．worthwhile 　　　　　　　　D．valuable

解析：选C。考查形容词辨析。句意：你花时间在业余爱好上值得吗？你的同学都集中精力学习功课。worth和worthy一般都用来表示主语“值得……”，而worthwhile则表示“做某事是值得的”。
