吸引;D.rebles反抗，背叛。劃線詞的本句中提到"...leavingaslight

negativechargeontheglasssurface.Whenwateristhen

C.personalstyleD.greatcapacity

【解析】

developcreativethinking,thisskill,justlikeamuscle,will

becomepooranduseless.'1可知創(chuàng)造力是要經(jīng)常練習(xí)的，如果不

練習(xí)，就會沒有用，下文說，如果一直練習(xí)創(chuàng)造力，它在使用的時候，

就可以用的上，所以it指的是“創(chuàng)造性的思維"，選A。

mechanism,通過它心臟和大腦可以互相交流來改善我們的情緒并

減少恐懼，排除A和D，又從前面看到是我們已經(jīng)發(fā)現(xiàn)了的一個重要

的mechanism,故只有B項mechanism意思相近，選B。

標(biāo)志，故C項正確。

Theunderlinedword“backfire"means.

A.haveanoppositeeffect

B.serveasapush

C.causeanger

D.avoidtakingthingsback

【解析】

A詞義猜測題。從后面的內(nèi)容可以了解到：孩布門會認(rèn)為大家都不喜

歡分享，正因為"他"這樣做了，才不得不獎賞"他"，在本段的最

后也說了，他們很肯在將來不去分享了，故這種因為分享而得到的獎

A.strengthB.positionC.steadinessD.visibility

【解析】

C詞義推斷題。句子：”...totallunareclipsecanlastforseveral

to?

A.Usingtoomuchpackaging.

C.Makingmoreproductsthannecessary.

在的句子的意思：我們以最可能環(huán)保的方式處理這種過度消費的結(jié)果,

但如果我們首先不需要帶那么多的材料回家應(yīng)該會更好。所以D項意

義正確。
