英語四級閱讀模擬題及四級閱讀答案
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)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.
練習題：

四級閱讀答案：
1.[B] 事實細節(jié)題。本題主要考査復合句的理解。第2段最后一句表明B是正確選項。選項A中的most和C中的only都太絕對了，文中并未對選項A和C中的相關說法加以這樣的限定。選項D也太絕對了，第2段第3句只是說到“大多數(shù)情況下是因為空調設計欠佳所致”,并不是說所有設計良好的大廈就不會發(fā)生這種情況。
2.[A] 事實細節(jié)題。本題考查復合句的理解。只要明白第3段第2句這個非限制性定語從句中的the bottoms of which中的which是指上文的reservoirs,問題就不難解決了。
3.[C] 事實細節(jié)題。本題考查被動語態(tài)長句的理解。在第3段第3句中，關鍵詞是highlight,選項C是對原句主謂部分的近義替換。選項A和B在文中皆無提及，選項D是過度使用生物殺滅劑的后果，與本題干的情況無關。
4.[A] 觀點態(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等詞說明作者認為要慎用這種殺滅劑。作者并沒對殺滅劑全盤否定，只是說過量使用會引發(fā)危險，因此選項D不對。
5.[C] 推理判斷題。本題考查代詞的理解。解題的關鍵在于理解最后一句中的This是指上一句所說的情況。選項A中所說的人造環(huán)境不是使免疫系統(tǒng)變弱的必然條件。選項B是保持免疫系統(tǒng)健康的條件。選項D是免疫系統(tǒng)變弱后的影響。
英語四級閱讀真題及答案
A letter to Edward,a columnist(報刊專欄作家)
Dear Mr. Expert：
I grew up in an unhappy and abusive home.I always promised myself that I’d get out as soon as possible.Now,at age 20,I have a good job and a nice house,and I’m really proud of the independence I’ve achieved. Here’s the problem：several of my friends who still live with their parents wish they had places like mine—so much so that they make mine theirs. It started out with a couple of them spending the weekends with me.But now they seem to take it for granted that they can show up any time they like.They bring boyfriends over,talk on the phone and stay out forever.
I enjoy having my friends here sometimes—it makes the place feel comfortable and warm—but this is my home,not a party house.I was old enough to move out on my own,so why can’t I seem to ask my friends to respect my privacy(隱私)?
Joan Edward’s reply to Joan
Dear Joan：
If your family didn’t pay attention to your needs when you were a child,you probably have trouble letting others know your needs now. And if you’ve gathered your friends around you to rebuild a happy family atmosphere(氣氛),you may fear that saying no will bring back the kind of conflict you grew up with—or destroy the nice atmosphere you now enjoy.You need to understand that in true friendship it’s okay to put your own needs first from time to time. Be clear about the message you want to send.For example,“I really love your company but I also need some privacy.So please call before you come over.”
Edward

四級閱讀理解答題技巧
技巧一：先看文章后作題
用這種方法應注意三點：
1、注意文章中心與作者基本觀點，即抓大的放小的。
2、注意重要細節(jié)的位置，第一遍閱讀時在了解主題之后知道某個東西在哪里，勝過你知道他是什么。
3、閱讀速度稍快。不能過分沉迷于原文，速度要快一點。
技巧二：先看問題再讀文章
要抓對重點適用于文章：
1、難度較大的文章
2、只包含一兩段的流水賬文章。流水賬文章段落少層次感較差，可以先看題目看清問題，確定大概的位置。
3、細節(jié)題較多的文章。缺點：對主題把握不夠明確。
技巧三：讀一層意思做一道題，讀文章做題交叉進行
本方法適用于：
1、段落較多的文章
2、閱讀速度較慢的同學。注意事項：每次閱讀一小段或者一長段的一半;閱讀速度比第一種閱讀方法要稍慢一些，力求弄清本段意思;每次讀新的內容之前，最好把接下來要回答的問題要先看一下。每篇文章為9分鐘，讀原文要5分鐘，做題要4分鐘。
通過以上的內容，我們已經(jīng)了解了四級閱讀答案的情況了，在做四級閱讀題目的時候，要熟練的掌握答題的技巧，這樣才能提高正確率，具體的可以咨詢聽力課堂。
