15.A

16.thosethose解析：本句的意思是“他們不認(rèn)為自己比別的不重要的人更好、更優(yōu)秀?！边@里比較的是down—to—earthpersons和別人。故答案為those。

17.WhenWhen解析：這里的一句話其實(shí)與下一半句“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。

18.outout解析：handout意為“分發(fā)，施舍”，為固定短語(yǔ)。

19.toto解析：revertto意為“重想，重提”，此句意為“如果你經(jīng)常提到‘我們以前已經(jīng)試著這樣做了，但是不管用’就會(huì)很快地挫傷這種好問(wèn)的頭腦”。

20.whowho解析：此空后的句子應(yīng)為teacher的定語(yǔ)從句，故此空處應(yīng)填who，引導(dǎo)修飾人的定語(yǔ)從句。

21.fromfrom解析：keepsth．fromdoingsth．意為“防止某事…”，為固定短語(yǔ)。

22.itit解析：本句意為“‘污染’意思是弄臟——表層土或什么東西，通過(guò)引進(jìn)雜質(zhì)，這使…不健康或不干凈?！憋@然，此空處應(yīng)指topsoilorsomething，因?yàn)榍懊嬉殉霈F(xiàn)，所以用it來(lái)代替。

23.likelylikely解析：前面所說(shuō)的thepersonwhoisdown-to-earth與thepersonwhosebothfeetontheground大體是一類(lèi)人，所以這里表達(dá)的意思是“很有可能就是一類(lèi)人”。belikelytodo就表達(dá)了這種意思。故答案為likely。

24.purposepurpose解析：從文中的第一句話“Themostobviouspurpose…”可以看出后面還有別的目的，而不是僅僅有最明顯的目的。故答案為purpose。

25.wherewhere解析：此題考查where引導(dǎo)的定語(yǔ)從句，修飾前面提到的plane，trainorbus。所以此處應(yīng)填關(guān)系副詞“where”。

26.B解析：由第一段的“Insteadofbeseechingusalltogetvaccinated，they’renowurgingmosthealthypeoplebetweentheagesof2and64,notto．”可以判斷出美國(guó)之呼吁2至64歲的健康人不接種流感疫苗，而不是所有的美國(guó)人，因此答案A是錯(cuò)誤的。從第二段最后一句話可以看出疫苗生產(chǎn)廠家無(wú)法臨時(shí)增加疫苗生產(chǎn)不是由于他們不愿意，而是由于受精雞蛋的生產(chǎn)已經(jīng)預(yù)先計(jì)劃好，無(wú)法提供更多的受精雞蛋，由此可見(jiàn)答案C是錯(cuò)誤的。從第三段第三行“Fluvaccinesareharderthanmosttoproducethisw
