選D。推理判斷題。根據(jù)第一段中Thebasicreasonisthatthesearethe

channelsthroughwhichwemaintaincontactwiththesurroundings.

Thoughapparentlyitmayfeelliketheseareindividualsensoryorgans,

theydoshowsomeconnectivity.“最基本的原因是，這些是我們與周圍

環(huán)境保持聯(lián)系的渠道。雖然很明顯這些似乎都是單獨的器官，但它們確

實也展現(xiàn)出了一些聯(lián)系。"可知，我們通過感覺器官感受和了解我們周

圍的世界。故選D。

2.Whatmayhappenafteryouhavehadarichlunch?

A.Youreyesbecomedim.

B.Youmayfeelenergeticandfresh.

C.Yourhearingpitchmaydecrease.

D.Yourtonguemaylosethefunctionoftaste.

選C。細(xì)節(jié)理解題。根據(jù)第一段Interestingly,ourhearingislesssharp

a代erweeataheavyfood.Isn/titgoodforasoundnapaftera

stomach-fullmeal?Thatdoesnotmeanwegodeafafterameal,but

thehearingpitchdoeschangeafteraheavymeal.可知,吃飽后人的聽

C.Atissuepaperistheonlythingthatcanbeusedtodryourtongues.

D.Ifyourtongueisdriedwithatissuepaper,itmayworkaswellas

Bo細(xì)節(jié)理解題。根據(jù)第二段內(nèi)容可知，舌頭必須在唾液的配合下才

能分辨味道，如果用紙把舌頭擦干，舌頭的味覺感知功能就會喪失，故

選Bo

4.Whatmakeseachpersondifferentfromanyoneelseexcepttwins?

A.Thenumberofsensoryorgans.

B.Thesensitivityofsensoryorgans.

C.Theparticularsmellofaperson.

D.Thestyleofone'sbehavior.

orindividualisticorcharacteristicsmell,whichisuniquetous,except

fortheidenticaltwins.,作者認(rèn)為除了一模一樣的雙胞胎之外,我們每

個人身上都有獨特的味道，通過這個味道我們就可以辨別我們所熟悉

的人，故選C。

【知識拓展】長難句分析

1.Thebasicreasonisthatthesearethechannelsthroughwhichwe

maintaincontactwiththesurroundings.

分析：句中的that引導(dǎo)表語從句，從句中的表語channels后跟有一個介

詞(through)+關(guān)系代詞(which)引導(dǎo)的定語從句。

翻譯：最基本的原因是，這些是我們與周圍環(huán)境保持聯(lián)系的渠道。

2.Tasteisnothingbutthefoodchemicalsdissolvedinthesalivabeing

sensedbythetastebudspresentonthetongue.

分析：dissolvedinthesaliva短語作定語，修飾foodchemicals;短語

beingsensedby...彳修飾salivao

翻譯：味覺不過是溶解在唾液中的食物化學(xué)物質(zhì)，而以被舌頭上的味

蕾感覺到。

【文章大意】本文介紹了青少年在運動中攻擊性行為的現(xiàn)象、成因以

及解決方法。

1.A.nativeB.negative

C.activeD.instructive

選B。由keephealthy及However表示的轉(zhuǎn)折關(guān)系可知，此處講的是運

動的負(fù)面影響，故選B。

2.A.poorB.high

C.specialD.unusual

選A。運動有可能會讓一些孩子的自尊心下降，并且?guī)砉粜缘男袨?

故A是最佳答案。

3.A.knockedB.glanced

C.smiledD.shouted

選D。在運動的過程中，他們聲稱自己曾被辱罵過或是被吆喝過。called

names和shoutedat在此處是近義詞，故選D。

4.A.impressionB.conclusion

C.tasteD.expectation

選A。正因為這樣，運動給許多兒童留下了不良的印象(impression),故

選A。

5.A.curiousB.violent

C.passiveD.pleasant

選Bo據(jù)前文提到的aggressive(有攻擊性的)一詞可知，孩子們認(rèn)為運動

太暴力(violent)了,故選B。

6.A.commonB.main

C.indirectD.different

選B。由第二段后面的內(nèi)容可知，教練和家長對小孩在運動中的暴力行

為負(fù)主要責(zé)任，也就是他們是小孩攻擊性行為的主要原因(maincause),

故選Bo

7.A.questionB.understand

C.copyD.ignore

選C。研究人員認(rèn)為兒童看了他們父母的攻擊性行為，然后就開始模仿

(copy),因此答案選C。

8.A.provedB.recovered

C.spreadD.benefited

選C。這種攻擊性行為在兒童之間又進(jìn)一步傳播/擴散(spread),故選C。

9.A.hardlyB.seldom

C.neverD.usually

選D。由powerful可知，父母和教練對小孩的影響很大，因為孩子們通

常(usually)很尊敬他們o

10.A.behaveB.communicate

C.argueD.blame

選Ao結(jié)合上文aggressiveadultbehavior,可知有時父母的行為舉止

(behave)也帶有攻擊性，故A是最佳選項。

11.A.winningB.practicing

C.enjoymentD.sport

選A。據(jù)下文提到的小孩受傷了，父母還是允許他們繼續(xù)比賽可知，他

們給孩子傳達(dá)一個信息：勝利(winning)至上，因此答案選A。

12.A.proudlyB.gently

C.aggressivelyD.bravely

選C。由parents...shoutinsults可知，當(dāng)小孩在運動中攻擊(behaves

aggressively)別人的時候，他們的父母也會歡呼喝彩。

13.A.acceptableB.capable

C.possibleD.enjoyable

選A。由even表示遞進(jìn)關(guān)系可知，父母甚至教導(dǎo)他們的小孩，侮辱其

他選手也是可以接受的(acceptable),因此選A。

14.A.WhileB.Where

C.HowD.When

選D。本句考查固定句型Whenitcomestosth./doingsth.當(dāng)涉及(做)

某事。

15.A.guidesB.examples

C.rolesD.partners

選B。談到如何預(yù)防兒童在運動中發(fā)生暴力行為，家長和教練應(yīng)該為小

孩樹立好榜樣(examples)。

16.A.methodsB.standards

C.valuesD.directions

選Co同時他們也應(yīng)該教會兒童什么才是人生更好的價值觀(values)。

17.A.comfortB.cheer

C.scoldD.celebrate

選Bo答案由第二段中的cheerwhentheirchildbehaves可得知。

18.A.lostB.tired

C.hatedD.injured

選Do第二段提至L..arepushedtocontinueplayingevenwhentheyare

injured,因此此處應(yīng)該是講當(dāng)小孩受傷(injured)時，不應(yīng)該讓他們繼續(xù)

比賽。同時，下一句Ifadultschildrentoplaywheninjured也揭示

了答案。

19.A.forceB.order

C.forbidD.permit

選D。句意：假如家長允許(permit)小孩在受傷的情況下還堅持參加運

動，這就透露出一條信息：比起健康(health),贏得比賽更重要。

20.A.performanceB.training

C.healthD.spirit

選C。答案由上一題的解+析可知。injured和身體的健康(health)有關(guān),

因此C是最佳選項。
