英语的学习需要大量的练习。下面是51自学小编收集整理的高二英语必修5Unit3的语法练习题目及其参考答案以供大家学习。     高二英语必修5Unit3的语法练习题目及答案   Ⅰ.单项填空   1.(2009年高考福建卷)________ not to miss the flight at 15∶20,the manager set out for the airport in a hurry.   A.Reminding   B.Reminded   C.To remind   D.Having reminded   解析:选B。句意:有人提醒经理不要错过15∶20的航班,他匆忙出发去了机场。本题考查非谓语动词作状语。主句主语the manager与remind之间的关系为逻辑上的动宾关系,故排除A、C、D三项,因为这三项表主动,而只有B项表被动。   2.(2010年高考湖南卷)Dina,________ for months to find a job as a waitress,finally took a position at a local advertising agency.   A.struggling B.struggled   C.having struggled D.to struggle   解析:选C。此处分词短语作时间状语,其逻辑主语Dina与struggle为主动关系,故排除B项。由句中的finally可知非谓语动词表示的动作发生在句中谓语took a position之前,故用现在分词的完成主动式。   3.(2009年高考江西卷)________ the right kind of training,these teenage soccer players may one day grow into international stars.   A.Giving B.Having given   C.To give D.Given   解析:选D。考查非谓语动词。如果把句子补充完整应该是:If they are given the right kind of training,可知主语they即these teenage soccer players与give之间是被动关系,所以用过去分词。而A、B、C三项都不表示被动含义。   4.(2009年高考四川卷)________ many times,he finally understood it.   A.Told B.Telling   C.Having told D.Having been told   解析:选D。考查非谓语动词。tell与主语之间的关系是被动关系,故排除表示主动意义的B项和C项。由状语many times可知tell这一动作在谓语动词understand之前发生过多次,所以用having been done来表示被动和完成。   5.(2009年高考天津卷)________ by the advances in technology,many farmers have set up wind farms on their land.   A.Being encouraged B.Encouraging   C.Encouraged D.Having encouraged   解析:选C。考查非谓语动词。由于主语many farmers和作状语的encourage之间是被动关系,排除表示主动意义的B项和D项。而being encouraged除表示被动外,还表示进行。农民们显然不是正在受到科技进步的鼓舞,故排除A项。   6.(2011年汕头高二检测)________ in 1636,Harvard is one of the most famous universities in the United States.   A.Being founded B.It was founded   C.Founded D.Founding   解析:选C。分析句子结构可知应选考查非谓语动词形式作状语的,排除B项,另外found与Harvard之间为被动关系,应用过去分词形式作状语,故选C。   7.(2011年晋中高二检测)________ as the “First Lady of Speech”,Dr Lillian Glass is recognized as one of the world’s leading experts on communication skills.   A.Knowing B.Having known   C.Known D.To be known   解析:选C。 be known as被称为……。Dr Lillian Glass与know之间为被动关系,应用过去分词形式作状语。A、B表主动,应排除;D项表将来,也可排除。   8.________ more attention,the trees could have grown better.   A.Given B.To give   C.Giving D.Having given   解析:选A。考查分词作状语。句子主语the trees与give之间是被动关系,而四个选项中只有A项表示被动意义,故答案选A。Given more attention相当于一个条件状语从句If the trees were given more attention。   9.________ in thought,he almost ran into the car in front of him.   A.Losing B.Having lost   C.Lost D.To lose   解析:选C。考查分词作状语。句意:由于陷入沉思,他差一点撞到前面的车上。be lost in thought为固定搭配,意为“陷入沉思”。过去分词短语lost in thought在句中作原因状语。   10.The research is so designed that once ________ nothing can be done to change it.   A.begins B.having begun   C.beginning D.begunw   解析:选D。考查分词作状语。句意:这项调查研究事先计划的如此完好,以至于一旦开始,什么也无法改变它。begin与research之间是被动关系,排除表示主动意义的A、B、C三项。once begun在句中作条件状语,它是状语从句once it is begun的省略形式。   11.Generally speaking,________ according to the directions,the drug has no side effect.   A.when taking B.when taken   C.when to take D.when to be taken   解析:选B。考查分词作状语。完整的说法应是when the drug is taken according to the directions...。由于主句的主语和从句的主语相同,因此可以省略从句的主语the drug和谓语的一部分is,故答案为B。   12.________ into use in April,2000,the hotline was meant for residents reporting water and heating supply breakdowns.   A.Put B.Putting   C.Having put D.Being put   解析:选A。考查过去分词作状语。句子的主语是the hotline与put into use“投入使用”存在被动关系,排除表示主动的B项和C项。D项表示正在投入使用,不符合语境。   13.In order not to be found,I spent the whole night ________ in my room.   A.locking B.locked   C.to lock D.lock   解析:选B。考查过去分词作状语。句意:为了不被找到,我整晚上都把自己锁在自己的房间里。lock的逻辑主语I和lock之间存在被动关系,故用过去分词作伴随状语。本题易受“spend... doing sth.句型的影响,易误选A。其实我并不是把整晚上的时间都用在了“锁”这一动作上,故排除A。   14.________,liquids can be changed into gases.   A.Heating B.To be heated   C.Heated D.Heat   解析:选C。考查过去分词作状语。句意:被加热时,液体可以变成气体。由于对于液体来说是加热的承受者,是被动的,因而选C。A项表示主动,B项表示目的,D项是谓语动词的形式。   15.Unless ________ to speak,you should remain silent at the conference.   A.invited B.inviting   C.being invited D.having invited   解析:选A。考查过去分词作状语。句意:除非受到邀请讲话,否则在大会上你应该保持沉默。invite与you之间是被动关系,排除B、D。being invited表示正在受到邀请,不符合语境。   Ⅱ.句型转换(把下列句子转变成过去分词作状语的结构)   1.If I am offered great help,I can get rid of all the difficulties.   ________ ________ ________,I can get rid of all the difficulties.   答案:Offered great help   2.Because she was frightened,she asked me to go with her.   ________,she asked me to go with her.   答案:Frightened   3.If he is given time,he’ll make a first?class tennis player.________________,he’ll make a first?class tennis player.   答案:Given time   4.He stood there silently,and he was moved to tears.
