Question

2．Starting the day on an egg could keep your blood pressure（血壓） under control，research suggests．Scientists have shown that eggs produce proteins with a function similar to that of powerful blood pressure-lowering drugs．
The research，from the University of Alberta in Canada，showed that when eggs come in contact with stomach enzymes（酶） they produce a protein that acts in the same way as Ace inhibitors，but more work is needed to show the effects outside a lab and in the human body．
Earlier this month，British researchers declared that，contrary to popular beliefs，it is healthy to go to work on an egg．They concluded that the type of cholesterol（膽固醇） found in eggs has little effect on increasing heart disease risks．
Researcher Professor Bruce Griffin，from the University of Surrey，said："The wrong beliefs linking egg eating to high blood cholesterol and heart disease must be corrected．The amount of fat in our diet has an effect on blood cholesterol that is several times greater than the relatively small amounts of cholesterol found in eggs．The UK public do not need to be limiting the number of eggs they eat．They can be encouraged to include them in a healthy diet as they are one of nature's most nutritious foods．"
The British Heart Foundation dropped its three-egg-a-week limit in 2005．However，almost half of Britons believe the limit still applies．

57．From the text we know that Ace inhibitors are．A
A．a(chǎn) kind of medicine                                 B．a(chǎn) kind of protein  
C．a(chǎn) kind of illness                                  D．a(chǎn) kind of food
58．According to what Professor Brcue said，eggs．C
A．a(chǎn)re the most nutritious food．
B．have no effect on blood cholesterol
C．can be included in a healthy diet  
D．a(chǎn)re forbidden to be eaten in the UK
59．We can infer from the text that．D
A．drugs to lower blood pressure will be replaced by eating eggs
B．stomach enzymes mixed with eggs can cure heart diseases
C．most Britons agree the three-egg-a-week limit should be dropped
D．a(chǎn)bout 50% of Britons think eating an egg a day is bad for their health
60．The text is meant．A
A．to introduce scientific findings about eggs
B．to introduce a medicine made from eggs
C．to tell people how to lower their blood pressure
D．to advise people to eat as many eggs as possible．

Answer 1

分析 研究發(fā)現(xiàn)，每天吃一個(gè)雞蛋對降低血壓大有裨益，雞蛋與胃酶結(jié)合后產(chǎn)生的蛋白質(zhì)與降壓藥物有著同樣的功效．

解答 57-60ACDA
57．A　推理判斷題．第一段的后半部分提到雞蛋產(chǎn)生蛋白質(zhì)的作用與強(qiáng)效降血壓藥物類似，此處與之相呼應(yīng)，表示雞蛋與胃酶結(jié)合后產(chǎn)生蛋白質(zhì)的作用與藥物相當(dāng)．由此可推知"ACE inhibitors"是一種藥．
58．C　細(xì)節(jié)理解題．根據(jù)倒數(shù)第二段最后一句的內(nèi)容可知，Bruce教授認(rèn)為雞蛋屬于健康食物．
59．D　推理判斷題．最后一段的最后一句提到幾乎一半的英國人相信對雞蛋的限制仍然適用，由此可推斷這些人依舊認(rèn)為每天吃一個(gè)雞蛋對健康有害．
60．A　主旨大意題．本文是一篇研究報(bào)告，第一段是文章的中心段，通讀全文可知，本文意在介紹關(guān)于雞蛋的科學(xué)發(fā)現(xiàn)．

點(diǎn)評 閱讀理解題測試考生在閱讀基礎(chǔ)上的邏輯推理能力，要求考生根據(jù)文章所述事件的邏輯關(guān)系，對未說明的趨勢或結(jié)局作出合理的推斷；或根據(jù)作者所闡述的觀點(diǎn)理論，對文章未涉及的現(xiàn)象、事例給以解釋．考生首先要仔細(xì)閱讀短文，完整了解信息，準(zhǔn)確把握作者觀點(diǎn)．
