課本單元練習：必修五Unit1 Great scientists

昨天和大家分享了Unit1 Great scientists的常考知識點，今天該做點練習鞏固一下啦！

Ⅰ. 單句語法填空

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

解析：本題考查非謂語動詞。句意：對那些與家人離得比較遠的人來說，個人電腦和電話在保持聯繫方面很重要。本句中的關鍵詞是stay(保持)，它是一個連繫動詞，後接形容詞作表語。connected是形容詞，意為「有聯繫的，有來往的」，符合句意。stay connected是「stay＋形容詞化的過去分詞」構成的系表結構。本題中的staying connected和keeping in touch表達同一個意思。

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

解析：本題考查非謂語動詞。句意：生產商定期來收回那些因為質量問題而被退回到我們商店的照相機。return此處意為「退回」，cameras與return之間是被動關係，故用過去分詞作後置定語，表示被動和完成的動作。

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

解析：句意：當小組討論接近尾聲時，一定要以重點而結束。

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：考查非謂語動詞。句意：為了在晚上保持溫暖，我會往爐子里添柴，並把鬧鐘定到午夜以便我可以起來給爐火添柴。to stay為不定式在句中作目的狀語。

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的複合結構。句意：這對老夫婦經常在晚飯後帶著他們的寵物狗在公園裡散步。在with的複合結構中，賓語their pet dog與賓語補足語之間為主動關係，故用following作賓語補足語。

6．—I hope to take the computer course.

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

解析：本題考查非謂語動詞。句意：——我希望能上電腦課。——好主意。要想了解更多，瀏覽這個網站。動詞不定式放於句首，作目的狀語，符合語境。

7．__A__73-year-old woman, who died of respiratory failure on Dec.6, was confirmed to have been carrying __the__H10N8virus.

解析：考查冠詞。句意：12月6日，一位73歲的婦女死於呼吸衰竭，她被確診攜帶H10N8病毒。第一空填不定冠詞表泛指；第二空填定冠詞表特指。

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

解析：考查非謂語動詞。句意：處理該化學物質時一定要小心，因為暴露在陽光下，它會爆炸。when後省略了句子的主語it(this chemical)和動詞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：考查連詞。句意：一些老師抱怨說「許多孩子沒有任何愛好，除非你把打電腦遊戲叫做一項愛好」。

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

解析：考查非謂語動詞作後置定語。觀察句子結構，不難發現句子已經有了謂語has had effect on，故應填入非謂語動詞。make與speech構成被動關係，結合時間狀語so far，故選過去分詞，即表被動又表完成。句意：老實說，迄今為止，這是對我最有影響的演講。

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

解析：考查學生對定語從句關係代詞、關係副詞的掌握情況。句意：用來種莊稼的土地養活的人口數量比放牧牲口的土地所供養的人口數量要多五倍。先行詞為land，關係詞在從句中作地點狀語，故填關係副詞where。

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

解析：本題考查定語從句。句意：請把所有申請這個職位的選手的信息發給我們。先行詞為information在定語從句中充當動詞have的賓語，且前有all修飾，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：考查非謂語動詞。句意：當他三個小時後回來時，他們仍坐在沙發上，聚精會神地交談。be absorbed in為固定搭配，意為「專心於」，所以此處應用absorb的過去分詞形式，作伴隨狀語。

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

—A gunman named James Eagan Holmes.

解析：問句句意：誰要為發生在美國電影院的槍擊案負責？be to blame為固定短語，意為「該受責備」。本身為被動含義，不用於被動語態。

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

解析：句意：縮小貧富之間的差距是這屆政府面臨的主要挑戰之一，Reducing the gap...the proor是動名詞短語做主語。

解析：not/never...until...「直到……才……」。
