1.細(xì)節(jié)理解題。根據(jù)"Theyhavespecialchemicals(化學(xué)物質(zhì))thatimproveyourabilitytofightoffsicknessand

youhavefewerchancesofgettingadisease.”可知，洋蔥能幫你戰(zhàn)勝疾病是因?yàn)樗鼈兒刑貏e的化學(xué)物質(zhì)。故

選D。

2.細(xì)節(jié)理解題。根據(jù)"Whenyoucutintoanonion,irritatingchemicalsinsidetheonionwillgetintotheair.They

touchyourwholeevesandcausepain.Youreyesmaketearstowashawaythechemicalsandprotectyoureyes.“可

知，當(dāng)你切洋蔥時(shí)，洋蔥內(nèi)部的刺激性化學(xué)物質(zhì)會(huì)進(jìn)入空氣中。它們會(huì)觸摸你的整個(gè)眼睛，引起疼痛。你

的眼睛會(huì)分泌眼淚來(lái)洗掉化學(xué)物質(zhì)，保護(hù)你的眼睛。故選C。

3.細(xì)節(jié)理解題o根據(jù)“?Cuttheonionunderrunningwater.?Useafantoblowairovertheonionasyoucutit.

?Puttheonioninafridgeforanhourbeforecutting.”可知，可以在流水下切洋蔥；切洋蔥時(shí)，可以用電風(fēng)扇

在上面吹氣；也可以把洋蔥放在冰箱里一小時(shí)后再切。故選項(xiàng)①②④符合題意，故選B。

4.推理判斷題。本文主要介紹了洋蔥的用途和營(yíng)養(yǎng)價(jià)值，也提供了幾種切洋蔥不流淚的方法。由此可推

測(cè)出，我們可以在雜志的生活與健康欄看到這篇文章。故選A。

6.細(xì)節(jié)理解題。根據(jù)"Whensmokecamefrombamboosticks,hefoundoutthathiswifewantedtouse

poisonous(有毒的)foodtokillhim”可知，想殺姜子牙的人是他的妻子。故選D。

7.詞句猜測(cè)題。根據(jù)“…ortaste”可知，空處的單詞和taste“味道”是并列關(guān)系，由此可推知。dor的含義是

“氣味”。故選C。

8.細(xì)節(jié)理解題o根據(jù)“Bamboohasbeenthemostpopularmaterialusedforchopsticksbecauseitisinexpensive,

easy-to-get,resistant（有抵抗力的）toheat,andhasnoterribleodorortaste.“可知，竹子用來(lái)做筷子的原因

有：價(jià)格便宜、易獲得、耐熱，并且沒(méi)有糟糕的氣味或味道。選項(xiàng)B“竹子長(zhǎng)得很快”不是用來(lái)做筷子的原

因。故選B。

9.推理判斷題。本文主要介紹了筷子的歷史以及和筷子的發(fā)明有關(guān)的三個(gè)傳說(shuō)，還介紹了制造筷子的多

種材料。因此可推知本文的寫(xiě)作目的是給我們介紹一些和筷子有關(guān)的信息。故選D。

無(wú)法被注意到，即因?yàn)槿四樧兓奶?，所以變化幾乎沒(méi)有被注意到。故選C。

11.推理判斷題。根據(jù)“Oneofthemainreasonsforthisisthewayinwhichwecannowcontrolpartsofnature.

Hundredsofthousandsofyearsago,allchangeswerenatural,butnowwecanactivelychoosewaysforourown

【導(dǎo)語(yǔ)】本文是一篇說(shuō)明文。文章主要介紹了20世紀(jì)70年代，一位名叫J.P.Guilford的心理學(xué)家進(jìn)行了

一項(xiàng)著名的關(guān)于創(chuàng)造力的研究，名為“九點(diǎn)謎題”，這讓Guilford得出了一個(gè)籠統(tǒng)的結(jié)論：創(chuàng)造力需要你跳

出框框。但是后來(lái)有人通過(guò)研究證明這個(gè)結(jié)論是一個(gè)誤導(dǎo)。
