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(jīng)濟關系發(fā)生深刻變化的原因。根據(jù)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(jīng)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(nèi)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(jù)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(nèi)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(jù)第二段，美國人不再把寵物看作是一種財產(chǎn)，

而是把它們看作和人一樣，并試圖在遺產(chǎn)中對它們作出安排。第三段則解釋了造

成這種轉(zhuǎn)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(chǎn)，但越來越多的寵物在遺產(chǎn)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(jù)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(nèi)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。
