2022年10月自考00015英語(yǔ)二考前模擬題(六)

Although many of us may feel air-conditioners bring relief from hot, humid or polluted outside air, they pose many potential health hazards. Much research has looked at how the movement of air inside a closed environment---such as an office building---can spread disease or expose people in the building to harmful chemicals.

One of the more widely publicized dangers is that of Legionnaire’s disease, which was first recognized inthe 1970s. This was found to have affected people in buildings with air-conditioning systems in which warmair pumped out of the system’ cooling towers was somehow sucked back into the air intake (通風(fēng)口),in mostcases due to poor design. The warm air, filled with bacteria,was combined with cooled, conditioned air andwas then circulated around various parts of the building. Studies showed that even people outside such buildings were at risk if they walked past air exhaust pipes.

Large air-conditioning systems add water to the air they circulate by means of humidifiers (濕度調(diào)節(jié)器).Inolder systems, the water used for this process is kept in special reservoirs, the bottoms of which providebreeding grounds for bacteria which can find their way into the ventilation (通風(fēng))system. The risk to human health from this situation has been highlighted by the fact that the immune systems (免疫系統(tǒng))of approximately half of workers in air-conditioned office buildings have developed the ability to fight off the organisms found at the bottom of system reservoirs. But chemicals called “biocides”are added to reservoirs to make them germ-free, and they are dangerous in their own right in sufficient quantities, as they often contain compounds strongly linked to cancers.

Finally, it should be pointed out that the artificial climatic environment created by air-conditioners canalso affect us. In a natural environment, whether indoor or outdoor, there are small variations in temperature and humidity. Indeed, the human body has long been accustomed to these normal changes. In an air-conditioned living or working environment, however, body temperatures remain well under37℃, our normal temperature. This leads to a weakened immune system and thus greater exposure to diseases such as colds and flu.

參考答案及解析

1.[B] 事實(shí)細(xì)節(jié)題。本題主要考査復(fù)合句的理解。第2段最后一句表明B是正確選項(xiàng)。選項(xiàng)A中的most和C中的only都太絕 對(duì)了，文中并未對(duì)選項(xiàng)A和C中的相關(guān)說(shuō)法加以這樣的限定。選項(xiàng)D也太絕 對(duì)了，第2段第3句只是說(shuō)到“大多數(shù)情況下是因?yàn)榭照{(diào)設(shè)計(jì)欠佳所致”,并不是說(shuō)所有設(shè)計(jì)良好的大廈就不會(huì)發(fā)生這種情況。

2.[A] 事實(shí)細(xì)節(jié)題。本題考查復(fù)合句的理解。只要明白第3段第2句這個(gè)非限制性定語(yǔ)從句中的the bottoms of which中的which是指上文的reservoirs,問(wèn)題就不難解決了。

3.[C] 事實(shí)細(xì)節(jié)題。本題考查被動(dòng)語(yǔ)態(tài)長(zhǎng)句的理解。在第3段第3句中，關(guān)鍵詞是highlight,選項(xiàng)C是對(duì)原句主謂部分的近義替換。選項(xiàng)A和B在文中皆無(wú)提及，選項(xiàng)D是過(guò)度使用生物殺滅劑的后果，與本題干的情況無(wú)關(guān)。

4.[A] 觀點(diǎn)態(tài)度題。第3段最后兩句討論生物殺滅劑的用處，其中最后一句中的but, dangerous和cancers等詞說(shuō)明作者認(rèn)為要慎用這種殺滅劑。作者并沒(méi)對(duì)殺滅劑全盤否定，只是說(shuō)過(guò)量使用會(huì)引發(fā)危險(xiǎn)，因此選項(xiàng)D不對(duì)。

5.[C] 推理判斷題。本題考查代詞的理解。解題的關(guān)鍵在于理解最后一句中的This是指上一句所說(shuō)的情況。選項(xiàng)A中所說(shuō)的人造環(huán)境不是使免疫系統(tǒng)變?nèi)醯谋厝粭l件。選項(xiàng)B是保持免疫系統(tǒng)健康的條件。選項(xiàng)D是免疫系統(tǒng)變?nèi)鹾蟮挠绊憽?/p>

以上就是有關(guān)“2022年10月自考00015英語(yǔ)二考前模擬題(六)”的全部?jī)?nèi)容了，希望能幫助各位自考生順利通過(guò)考試，加油！
