B.allsensoryorgansareconnectedandcanbeexchanged

C.sensoryorgans'functionscanneverbechangedfortheirparticular

character

D.wefeelandlearnabouttheworldaroundusthroughoursensory

organs

选D。推理判断题。根据第一段中Thebasicreasonisthatthesearethe

channelsthroughwhichwemaintaincontactwiththesurroundings.

Thoughapparentlyitmayfeelliketheseareindividualsensoryorgans,

theydoshowsomeconnectivity.“最基本的原因是，这些是我们与周围

环境保持联系的渠道。虽然很明显这些似乎都是单独的器官，但它们确

实也展现出了一些联系。"可知，我们通过感觉器官感受和了解我们周

围的世界。故选D。

2.Whatmayhappenafteryouhavehadarichlunch?

A.Youreyesbecomedim.

B.Youmayfeelenergeticandfresh.

C.Yourhearingpitchmaydecrease.

D.Yourtonguemaylosethefunctionoftaste.

D.Ifyourtongueisdriedwithatissuepaper,itmayworkaswellas

Bo细节理解题。根据第二段内容可知，舌头必须在唾液的配合下才

能分辨味道，如果用纸把舌头擦干，舌头的味觉感知功能就会丧失，故

选Bo

4.Whatmakeseachpersondifferentfromanyoneelseexcepttwins?

A.Thenumberofsensoryorgans.

B.Thesensitivityofsensoryorgans.

C.Theparticularsmellofaperson.

D.Thestyleofone'sbehavior.

选C。细节理解题。根据最后一段Eachandeveryoneofushasaparticular

orindividualisticorcharacteristicsmell,whichisuniquetous,except

fortheidenticaltwins.,作者认为除了一模一样的双胞胎之外,我们每

个人身上都有独特的味道，通过这个味道我们就可以辨别我们所熟悉

的人，故选C。

【知识拓展】长难句分析

1.Thebasicreasonisthatthesearethechannelsthroughwhichwe

maintaincontactwiththesurroundings.

分析：句中的that引导表语从句，从句中的表语channels后跟有一个介

词(through)+关系代词(which)引导的定语从句。

翻译：最基本的原因是，这些是我们与周围环境保持联系的渠道。

2.Tasteisnothingbutthefoodchemicalsdissolvedinthesalivabeing

sensedbythetastebudspresentonthetongue.

分析：dissolvedinthesaliva短语作定语，修饰foodchemicals;短语

beingsensedby...彳修饰salivao

翻译：味觉不过是溶解在唾液中的食物化学物质，而以被舌头上的味

蕾感觉到。

18.A.lostB.tired

injured,因此此处应该是讲当小孩受伤(injured)时，不应该让他们继续

比赛。同时，下一句Ifadultschildrentoplaywheninjured也揭示

了答案。

19.A.forceB.order

C.forbidD.permit

选D。句意：假如家长允许(permit)小孩在受伤的情况下还坚持参加运

动，这就透露出一条信息：比起健康(health),赢得比赛更重要。
