　　英語四級(jí)考試閱讀模擬題答案

　　1.[B] 題干的句子是文章第1段第3句，這是一個(gè)帶有插入語的簡(jiǎn)單句，contrary在此表示跟part of nature相反，因此答案為B。

　　2.[D] 第2段最后一句提到，我們必須更加關(guān)注吸收少量殺蟲劑的潛在后果，它們正在不知不覺地污染我們的世界。因此，作者對(duì)殺蟲劑對(duì)環(huán)境的影響關(guān)注且擔(dān)憂,D符合題意。

　　3.[A] 第2段第2句提到，殺蟲劑使人突然發(fā)病或者死亡是很令人難過的亊，對(duì)于人口整體來說，人類對(duì)殺蟲劑長(zhǎng)期累計(jì)的潛在后果的認(rèn)識(shí)不足，才是最嚴(yán)重的問題，故選A。

　　4.[C] 根據(jù)第3段倒數(shù)第2句說的“對(duì)未來的災(zāi)難無動(dòng)于衷是人的本性”以及最后一句說的"大多數(shù)人只對(duì)有明顯跡象的疾病予以關(guān)注”可知C正是人們忽視化學(xué)藥物的潛在危害的原因，故選C。

　　5.[D] Dubos博士話中“最可怕的敵人”指的是“殺蟲劑引起的潛在危險(xiǎn)”，博士話中的slowly approach them unnoticed直接表明D正確。

　　英語四級(jí)考試閱讀模擬題(二)

　　Just seven years ago, the Jarvik-7 artificial heart was being cheered as the model of humancreativeness. The sight of Barney Clark-alive and conscious after trading his diseased heart fora metal-and-plastic pump-convinced the press, the public and many doctors that the futurehad arrived. It hadn’t. After monitoring production of the Jarvik-7, and reviewing its effects onthe 150 or so patients (most of whom got the device as a temporary measure) the U.S. Foodand Drug Administration concluded that the machine was doing more to endanger lives thanto save them. Last week the agency cancelled its earlier approval, effectively banning (禁止)the device.

　　The recall may hurt Symbion Inc., maker of the Jarvik-7, but it won’t end the request for anartificial heart. One problem with the banned mode is that the tubes connecting it to anexternal power source createda passage for infection. Inventors are now working on newdevices that would be fully placed, along with atiny power pack, in the patient’s chest. The firstsample products aren’t expected for another 10 or 20 years. But some people are alreadyworrying that they’ll work—and that America’s overextended health—care programs will lose aprecious $2.5 billion to $5 billion a year providing them for a relatively few dying patients. Ifsuch expenditures (開支) cut into funding for more basic care, the net effect could actually be adecline in the nation’s health.

　　1. According to the passage, the Jarvik-7 artificial heart proved to be _____.

　　B. will review the effects of artificial hearts before designing new models

　　英語四級(jí)考試閱讀模擬題答案

　　1.[A] 文章一開頭說Jarvik-7以前被認(rèn)為是一大技術(shù)成就，但文章第1段倒數(shù)第2句中提到,美國食品與藥品管理局得出結(jié)論,認(rèn)為這種儀器與其說是挽救生命,不如說是將生命置于更加危險(xiǎn)的境地。由此可知Jarvik-7是一個(gè)技術(shù)失敗,故選A。

　　2.[C] 文章第2段第1句提到，要求生產(chǎn)人造心臟的Symbion公司召回其銷售的人造心臟，這對(duì)該公來說或許是一種損失，但這一禁令不會(huì)終結(jié)人們對(duì)人造心臟的需求。從這一句可推斷出應(yīng)選C。原文只提到政府禁止Jarvik-7這種型號(hào)的人造心臟，A把范圍擴(kuò)大到了所有的人造心臟;B在原文中并未提及;D說的對(duì)象不是Symbion公司，也可排除。

　　3.[B] 文章中第2段第3句提到，這種新儀器可以完全置于患者的胸腔內(nèi)，B與之相符，故選B。A在文中并未提及;C、D說的對(duì)象是Jarvik-7，故也排除。

　　4.[D] 從句子意思看，“向?yàn)閿?shù)不多的瀕危病人提供” 的顯然是上一句中的sample products，即可與電源組一并植于人體內(nèi)的new devices，故選D。

　　5.[B] 第2段倒數(shù)第2句But some people are already worrying…這句話體現(xiàn)了有些人已經(jīng)在擔(dān)心，為為數(shù)不多的垂危病人動(dòng)用巨額資金購置新型的人造心臟是否合算，而由該段最后一句可以看出作者認(rèn)為這樣的做法是不明智的，因此B是答案。
