本文作者寫作步驟如下:什么是小行星;小行星可能撞擊地球的時間及其后果;

科學家關于避免小行星撞擊地球的方法;人們對解決問題方法的憂慮。所以,讀

12

者可以推斷出:如果對付小行星的核武器在改變小行星運行軌道的同時會毀滅整

個地球,那么解決小行星撞擊地球的可行的辦法仍需進一步研究。故選D。

A.morepeoplenowownvetsthanbefore

B.peopleownmorepetstodaythanbefore

C.thecostofpetfoodhasdecreased

D.peoplespendmoremoneyontheirpets

參考答案:D

答案解析:

該題要求理解美國人和他們的寵物之間的經濟關系發(fā)生深刻變化的原因。根據第

二段,雖然飼養(yǎng)寵物的人數(shù)沒有什么增加,但花在寵物身上的費用增加了。因此,

造成美國人和他們的寵物之間的經濟關系發(fā)生深刻變化的原因,是美國人在寵物

的身上花了更多的錢。

第37題:

A.WhoownpetsintheUnitedStates?

B.Whydopeopleraisepets?

C.Whatarethecostsofowningpets?

D.Whatarethemedicalbenefitsofowningpets?

參考答案:B

答案解析:

該題要求理解第四、五段的主要內容。在第,四段,作者指出飼養(yǎng)寵物可以使人

們更有人情味;根據第五段,年輕人有更多的時間來飼養(yǎng)寵物,以及飼養(yǎng)寵物可

以降低血壓和防止心臟病。所以這兩段的內容主要回答了選項B提出的問題。

第38題:

Theword"metamorphosis”(para.4)couldbestbereplacedby.

A.change

B.improvement

C.understanding

D.attitude

14

參考答案:A

答案解析:

該題要求從上下文猜測詞義。根據第二段,美國人不再把寵物看作是一種財產,

而是把它們看作和人一樣,并試圖在遺產中對它們作出安排。第三段則解釋了造

成這種轉變的原因。

第39題:

Thepassagesupportswhichofthefollowingstatements?

A.Americanssetdownpetsaspropertyintheirwills.

B.Mostlawyersownpetsofonekindoranother.

C.Peopleintheir20sand30sgivetheirprioritytoraisingpets

ratherthanhavingchildren.

D.ThenumberofpetsintheU.S.thathaveinsurancepoliciesisless

than1.14million.

參考答案:D

答案解析:

該題要求理解文章中部分句子的意思。選項A錯。第三段括號中的一句話是說,

雖然寵物在法律上不能繼承財產,但越來越多的寵物在遺產中得到了安排;選項

B錯。作者在第四段中引用了LaneGabeler律師作為一個例子,說明寵物使一

些令人討厭的工作更富有人情味,但并不說明大多數(shù)律師都擁有寵物;選項C

錯。第五段第二句的意思是說,年輕人由于推遲生兒育女,從而有時間來飼養(yǎng)寵

物,不是因為飼養(yǎng)寵物而推遲生兒育女;選項D對。根據第六段第四句,美國的

11,400萬只寵物只有不到現(xiàn)有健康保險。

第40題:

Whatdoestheauthormeanby"themarkethashardlybeenscratched”(para.

6)?

A.VeryfewAmericanpetshaveinsurancepolicies.

B.Morepeoplewillownpetsinthefuture.

C.Americansspendlessmoneyonpetsthanpeopleinothercountries.

D.FewpetsinAmericadiefromaccident.

參考答案:A

答案解析:

該題要求理解第六段的主要內容。該段主要說的是,美國只有1%的寵物有健康

保險,而英國和瑞典分別為13%和57%O從這個意義上來說,美國寵物保險市場

還未啟動,其前途大有可為。
