Question

20．Organic food，once considered something that only health fanatics desired，is now a regular feature at most supermarkets．And that has created a bit of a dilemma．On the one hand，you have a conventionally grown apple．On the other，you have one that's organic．Both apples are firm，shiny and red．Both provide vitamins and fiber，and both are free of fat，sodium and cholesterol．
Conventionally grown food generally costs less，but is organic food a better choice？The advantages claimed for such foods over conventionally grown and sold food products are now being debated on a large scale．Supporters of organic foods-a term whose meaning varies greatly-are frequently telling the world that such products are safer and more nutritious than others．
The growing interest of consumers in the safety and nutritional quality of daily foods is a welcome development．However，much of this interest has been aroused by sweeping claims that the conventional food supply is unsafe or inadequate in meeting nutritional needs．
Almost daily，the public is surrounded by claims for"no-aging"diets，new vitamins and other wonder foods．There are numerous unsubstantiated（沒證實的） reports that natural vitamins are superior to man-made ones，that fertilized eggs are nutritionally superior to unfertilized eggs，that untreated grains are better than those treated with insect spray and the like．
Although most of these claims are not supported by scientific evidence，large amounts of written material about the benefits of organic foods makes it difficult for people to separate fact from fiction．As a result，claims that eating a diet consisting of organically grown foods prevents or cures disease or provides other benefits to health have become widely advertised and form the basis for people's opinion．
One thing that most organically grown food products seem to have in common is that they cost more than conventionally grown foods．But in many cases consumers are misled if they believe organic foods can maintain health and provide better nutritional quality than conventionally grown foods．So there is real cause for concern if consumers，particularly those with limited incomes，distrust the conventional food supply and buy only expensive organic foods instead．
41．According to Paragraph 2，which of the following statements about organic food is true？B
A．It hasn't been used until recent years

A．most doctors believe organic foods prevent disease or provide other benefits to health
B．organic foods are actually less nutritious than conventionally grown foods
C．people cannot separate fact from fiction because of the TV advertisements
D．organic foods cost more but are not necessarily better than conventionally grown foods
44．According to the passage，many consumers are attracted by organic foods because theyC
A．want to try something new               
B．have carefully researched the products
C．value food safety and nutrition             
D．expect to save some money
45．What is the author's attitude towards the claims of organic foods？A
A．Doubtful．B．Enthusiastic．C．Supportive．D．Uninterested．

Answer 1

分析 本文屬于說明文閱讀，作者通過這篇文章主要向我們描述了有機食品越來越受很多消費者的歡迎．但有機食品真的比普通食品很好、更安全這還有待證實．

解答 41．B．細(xì)節(jié)理解題．根據(jù)第二段的內(nèi)容"Supporters of organic foods-a term whose meaning varies greatly-are frequently telling the world that such products are safer and more nutritious than others"可知對于有機食品沒有統(tǒng)一的界定．故選B項．
42．C．細(xì)節(jié)理解題．根據(jù)t第四段That untreated grains are better than those treated with insect spray and the like．用藥噴灑的莊稼是傳統(tǒng)的糧食作物．故C正確．
43．D．推理判斷題．根據(jù)第二段第一句"Conventionally grown food generally costs less…"及最后一段第一句"One thing that most organically grown food products seem to have in common is that they cost more than con？ventionally grown food…"可以推知有機食品價格高，但不一定比傳統(tǒng)的食物更好．故選D項．
44．C．細(xì)節(jié)理解題．根據(jù)最后一段中"But in many cases consumers are misled if they believe organic food can maintain health and provide better nutritional quality than conventionally grown food．"可知，消費者被有機食品吸引是因為他們太看重食物的安全與營養(yǎng)．故選C項．
45．A．推理判斷題．根據(jù)最后一段"But in many cases consumers are misled if they believe organic foods can maintain health and provide better nutritional quality than conventionally grown foods"可以看出作者對有機食品是持懷疑態(tài)度的．故選A項．

點評 考察學(xué)生的細(xì)節(jié)理解和推理判斷能力，做細(xì)節(jié)理解題時一定要找到文章中的原句，和題干進行比較，再做出正確的選擇．在做推理判斷題不要以個人的主觀想象代替文章的事實，要根據(jù)文章事實進行合乎邏輯的推理判斷．
