專(zhuān)題限時(shí)訓(xùn)練（十八）

㈠

本文是說(shuō)明文。全文說(shuō)明了一項(xiàng)關(guān)于青少年吸煙問(wèn)題的調(diào)查。調(diào)查顯示，青

少年吸煙的人數(shù)在過(guò)去的五年里呈下降趨勢(shì)，但也有人對(duì)此數(shù)據(jù)表示懷疑。

1.A聯(lián)系后文Cigarettesmokingisthe…causeofpreventabledeath

anddiseaseinthiscountry.我們知道，這是對(duì)全國(guó)424個(gè)學(xué)校的調(diào)查。

2.C聯(lián)系空后from21percentin2002,to12percentin2007我們

知道，數(shù)量在下降。

3.B對(duì)于青少年關(guān)于吸煙危害的教育是數(shù)量下降的原因。result指“結(jié)

果"；reason指"理由"；excuse意思是"借口”。

4.D聯(lián)系前文的數(shù)據(jù)我們知道青少年吸煙人數(shù)在下降。因此此空用dropo

5.A聯(lián)系空后的thehighratesofteenagers我們知道，個(gè)人與組織

一直以來(lái)試圖降低高比率。

6.A聯(lián)系空后的內(nèi)容我們知道，香煙價(jià)格的日益高漲是青少年吸煙人數(shù)

減少的重要原因。

7.Bwhateverthereason是whateverthereasonis的省略形式，

whatever引導(dǎo)了讓步狀語(yǔ)從句，相當(dāng)于nomatterwhato

8.C聯(lián)系空后theirproductisonlyforadults我們知道，香煙公司

提出告誡。

9.C前后為因果關(guān)系，因此可排除其他選項(xiàng)。

10.A聯(lián)系空后的內(nèi)容，Whileitistruefewerteensaresmokingtoday

thanfiveyearsago,therateofteensmokingisstillhigherthanitwas.

我們知道，目前情況仍不容樂(lè)觀。

11.A吸煙是……的首要原因。B有一定干擾性，可以說(shuō)partofthe

reason,意思是“部分原因”。

12.D調(diào)查表明(suggests)很多青少年仍不能理解吸煙的危害性。

(-)

本文是說(shuō)明文。全文講述了通過(guò)研究，發(fā)現(xiàn)樂(lè)觀輕松的人患感冒的機(jī)會(huì)

很少。

13.B聯(lián)系文章最后一■段…whethernegativeemotionsorpositive

emotionshaveastrongereffectonhowhealthyweare我們知道，對(duì)此人

們還不能確定，只是有可能。

14.D聯(lián)系前文的cheerfulandrelaxed我們可以得此答案。本題中其他

選項(xiàng)均有一定干擾性。general一般的；standard標(biāo)準(zhǔn)的；passive被動(dòng)的。

15.
