16.olderolder解析:grow只能是年齡越來越大。

17.toto解析:“shift”意為“轉(zhuǎn)變”,“從…到…的轉(zhuǎn)變”應(yīng)該用介詞“to”。所以此處應(yīng)填“to”。

18.ofof解析:“對現(xiàn)實(shí)的了解”的英文表達(dá)是“theunderstandingofreality”,這里的介詞用of。故答案為of。

19.withoutwithout解析:此處意為年輕人更喜歡沒有重大責(zé)任的簡單工作。所以此處應(yīng)填“without”。

20.suchsuch解析:“such…as”用來舉例子。所以此處應(yīng)填“such”。

21.importantimportant解析:從本句后面的一句話可以看出,Adown-to-earthperson就算是重要的人物,他們也不會(huì)把這種顯赫寫在臉上。所以前面應(yīng)填important。故答案為important.

22.WhenWhen解析:這里的一句話其實(shí)與下一半“whenwearedown-to-earth….”所起到的作用是一樣的,同時(shí)兩者也是并列的,when表達(dá)了“當(dāng)…”,所以這里填when。故答案為when。

23.whosewhose解析:這是一個(gè)后置定語從句,用whose來引導(dǎo),表示mind與dreamer的所屬關(guān)系。故答案為whose。

24.importantimportant解析:從本句后面的一句話可以看出,Adown-to-earthperson就算是重要的人物,他們也不會(huì)把這種顯赫寫在臉上。所以前面應(yīng)填important。故答案為important。

25.dodo解析:解析見上題,為了避免與前面的know重復(fù),這里可以換做do。故答案為do。

26.C解析:由C中“‘WillesdenGreenhasadiverserangeofpropertiesfrom1930ssemi-detachedhousestolargeVictorianpropertiesandnew-buildswhichattractallkindsofbuyers',saysRichardChiti,salesmanageratestateagentsEllisandCo.”可以看出WillesdenGreen是一個(gè)文化

27.C解析:文章第二段對于基因治療的方式的解釋是用于治療的基因通過“virusesthatdon'tcausehumandisease”進(jìn)入體內(nèi),就好像“特洛伊木馬”一樣,由此可見,這些病毒是無害的。因此正確答案為C。

28.B解析:原文的第三段最后“Whattheydidnotknow…followedapattern—whatisreferredtoa
