高二英语必修五练习Unit1 Great scientists

　　Ⅰ. 单句语法填空

　　1．For those with family members far away， the personal computer and the phone are important in staying __connected__(connect)．

　　解析：本题考查非谓语动词。句意：对那些与家人离得比较远的人来说，个人电脑和电话在保持联系方面很重要。本句中的关键词是stay(保持)，它是一个连系动词，后接形容词作表语。connected是形容词，意为“有联系的，有来往的”，符合句意。stay connected是“stay＋形容词化的过去分词”构成的系表结构。本题中的staying connected和keeping in touch表达同一个意思。

　　2．The producer comes regularly to collect the cameras__returned__(return) to our shop for quality problems.

　　解析：本题考查非谓语动词。句意：生产商定期来收回那些因为质量问题而被退回到我们商店的照相机。return此处意为“退回”，cameras与return之间是被动关系，故用过去分词作后置定语，表示被动和完成的动作。

　　3．When the group discussion is nearing its end， make sure to conclude it __with__ important points.

　　解析：句意：当小组讨论接近尾声时，一定要以重点而结束。

　　4．__To_stay__(stay) warm at night， I would fill the woodstove， then set my alarm clock for midnight so I could refill it.

　　解析：考查非谓语动词。句意：为了在晚上保持温暖，我会往炉子里添柴，并把闹钟定到午夜以便我可以起来给炉火添柴。to stay为不定式在句中作目的状语。

　　5．The old couple often take a walk after supper in the park with their pet dog __following__(follow) them.

　　解析：考查with的复合结构。句意：这对老夫妇经常在晚饭后带着他们的宠物狗在公园里散步。在with的复合结构中，宾语their pet dog与宾语补足语之间为主动关系，故用following作宾语补足语。

　　6．—I hope to take the computer course.

　　—Good idea.__To_find__(find) out more about it， visit this website.

　　解析：本题考查非谓语动词。句意：——我希望能上电脑课。——好主意。要想了解更多，浏览这个网站。动词不定式放于句首，作目的状语，符合语境。

　　7．__A__73-year-old woman， who died of respiratory failure on Dec.6， was confirmed to have been carrying __the__H10N8 virus.

　　解析：考查冠词。句意：12月6日，一位73岁的妇女死于呼吸衰竭，她被确诊携带H10N8病毒。第一空填不定冠词表泛指；第二空填定冠词表特指。

　　8．Be careful when you deal with this chemical， as it will explode when __exposed__(expose) to sunlight.

　　解析：考查非谓语动词。句意：处理该化学物质时一定要小心，因为暴露在阳光下，它会爆炸。when后省略了句子的主语it(this chemical)和动词be的形式is，所以填exposed。

　　9．Some school teachers complained， “Many kids haven't got any hobbies— __unless__ you call playing computer games a hobby.”

　　解析：考查连词。句意：一些老师抱怨说“许多孩子没有任何爱好，除非你把打电脑游戏叫做一项爱好”。

　　10．To be honest， no speech __made__(make) so far has had the same effect on me as this one.

　　解析：考查非谓语动词作后置定语。观察句子结构，不难发现句子已经有了谓语has had effect on，故应填入非谓语动词。make与speech构成被动关系，结合时间状语so far，故选过去分词，即表被动又表完成。句意：老实说，迄今为止，这是对我最有影响的演讲。

　　11．Land used to grow crops feeds five times more people than land __where__animals are kept.

　　解析：考查学生对定语从句关系代词、关系副词的掌握情况。句意：用来种庄稼的土地养活的人口数量比放牧牲口的土地所供养的人口数量要多五倍。先行词为land，关系词在从句中作地点状语，故填关系副词where。

　　12．Please send us all the information __that__ you have about the candidate for the position.

　　解析： 本题考查定语从句。句意：请把所有申请这个职位的选手的信息发给我们。先行词为information在定语从句中充当动词have的宾语，且前有all修饰，故只能用that。

　　13．When he came back three hours later， they were still sitting on the sofa， __absorbed__(absorb) in conversation.

　　解析：考查非谓语动词。句意：当他三个小时后回来时，他们仍坐在沙发上，聚精会神地交谈。be absorbed in为固定搭配，意为“专心于”，所以此处应用absorb的过去分词形式，作伴随状语。

　　14．—Who is __to_blame__(blame) for the shooting at a movie theatre in America？

　　—A gunman named James Eagan Holmes.

　　解析：问句句意：谁要为发生在美国电影院的枪击案负责？be to blame为固定短语，意为“该受责备”。本身为被动含义，不用于被动语态。

　　15．__Reducing__(reduce) the gap between the rich and the poor is one of the main challenges facing the government.

　　解析：句意：缩小贫富之间的差距是这届政府面临的主要挑战之一，Reducing the gap...the proor是动名词短语做主语。
