答案與題解:
1.A 本題應選擇 attack,因為第一句說到:人們認為鯊魚是 a deadly enemy,也就是說鯊魚會對人類造成傷害。第二句是對 deadly enemy的具體說明。其他的三個選項 meet,love,visit都不合適, love與上下文意思相反, meet和 visit與上下文意思不符。
2.C 空格 2所在的句子由 but連接,所以該句子表達的意思一定與第二句相反。第二句對鯊魚的評價是負面的,填入空格 2的詞應該是正面的。四個選項中只有 valuable符合這一條件,所以是答案。
3.B 第三句說到鯊魚有益于 “waters and human beings”,第五句又說到鯊魚瀕臨滅絕的`危險。根據(jù)上下文的意思,threatening(威脅)到它們的應該是 existence(生存)。其他的三個選項 source,friends,fish都不合適,與上下文意思沒有聯(lián)系。
4.D 如果鯊魚消失,從什么地方消失呢 ?當然從 earth(地球)上消失。從 space(宇宙空間)、 sky(天空)
中消失,或從 land(陸地)上消失,都有悖常理。
5.C 四個選項的意思都是 “因為“,但是從用法上分析, because、since和 by reason that之后要接句子, because of之后接名詞或名詞短語。 their warm waters是名詞短語,所以要選用 because of。
6.D “… people also swim”明顯是定語從句,其先行詞是表示地點的名詞 area,所以要選關系副詞 where。
7.B 從上下文判斷,本句的意思是:鯊魚將人錯認為是海洋動物。而“將……錯認為是 ”的英語表達是 mistake … for,所以本題的答案是選項 B。
8.A 本段的意思是:鯊魚并非故意襲擊人類。人們認為,由于鯊魚將人錯認為是海獅等海洋動物,在饑餓時才襲擊人類。日出和日落時,正是鯊魚饑腸轆轆的時候,人們不應該出海游泳?崭 8填入的詞應該與時間有關,所以 times是答案,而與地點有關的選項( places seas和 oceans)與上下文意思脫節(jié)。
9.C 本段第一、二句是說,鯊魚的嗅覺特別靈敏,能嗅到海水中存在的極為微量的氣味。作者舉了三個物質:血、體液和化學品?崭 9要填入表示物質的名詞。四個選項中惟一表達物質的詞是 chemicals(化學品)。所以 chemicals是答案,而其它三個選項與學科有關,脫離了上下文的意思,不是本題的答案。
10.B 在第一、二句意思的基礎上,作者進一步說明,靈敏的嗅覺有助于鯊魚找到食物。所以本題的答案是選項 D的 senses,因為 feelings,touches和 tastes都與 smells無關。
11.D 本句的中心詞是復數(shù)的 sharks,another所修飾的名詞一般是單數(shù),所以不會是答案。 these和 those是表特指的代詞,指代前面出現(xiàn)過的名詞。由于前面沒有先行詞,所以也不可能是答案。剩下的 other是答案, any other sharks的說法也合乎英語的用法。
12.A 從上下文判斷,醫(yī)學研究人員想要更多了解的是 “身體抗病 system(系統(tǒng)) ”,不會是 “身體抗病 idea(思想)”、“身體抗病工作( work)”或“身體抗病 circle(周期) ”。
13.A 本段昀后一句的意思是:醫(yī)學研究人員研究鯊魚的目的是為了找到一種人類抗病的方法。所以空格 l3所在句子的意思應該是 recover(quickly from injuries)。科學家想要探索的應該是有關受傷鯊魚 recover quickly from injuries的秘密,而 reform(改造)、 return(回歸)和 rely(依靠)只是與答案 recover詞形上有點相似而已,其意思與上下文的意思風馬牛不相及。
14.B 從上下文判斷,鯊魚的存在能使 oceans得益。鯊魚不生活在 rivers、forests或 mountains中,所以,這三個選項不會是答案。
15.D 本段的其余三句都是說明為什么鯊魚有益于海洋。它們吃海洋動物,結果使得海洋中的動物數(shù)量不會過多。 weak、little、few都與上面表達的意思相反,所以,只有 great是答案。
