irradiating（照射）fruits, vegetable, pork and chicken to kill insects and bacteria has been approved by the Food and Drug Administration over the past decade or so.Irradiation of other meats, such as beef and lamb,is being reviewed.Federal approval dose not require that industry adopt the process,and few food processors presently offer irradiated products.
Market studies have shown that many consumers are afraid that eating irradiated food may cause cancer,despite scientific studies that prove the safety of treated food.Some people argue that more severe government inspection,higher food-safety standards,and more careful food-preparation practices by consumers are all that is needed to ensure that food is safe.Consequently,companies currently see no need to spend millions of dollars outfitting（配备）processing plants with the equipment necessary for a process that very few shoppers are in favor of.
All supermarkets that sell irradiated food must label that food either directly on the packaging or in the case of bulk items like fruits and vegetables by placing a sign nearby. There is no requirement for the labeling of irradiated food served by chain restaurants or hospitals that buy directly from distributors,nor any regulations for products that contain irradiated ingredients.
Presently,the FDA allows food to be treated with three types of radiation一gamma rays,highenergy electrons,and X-rays,and sets limits on doses（辐射量）depending on the type of food. The principle is that the dose to be used for a certain type of food should not exceed the amount that is sufficient to kill most harmful insects and bacteria present in it.Different types of food,because of their different molecular（分子）compositions,may require different doses of radiation.

第1题：
The food we eat seems to have profound effects on our health.Although science has made enormous steps in making food more fit to eat ,it has, at the same time,made many foods unfit to eat. Some research has shown that perhaps eighty percent of all human illnesses are related to diet and forty percent of cancer is related to the diet as well,especially cancer of the colon. Different cultures are more likely to cause certain different illnesses because of the food that is characteristic in these cultures. That food is related to illness is nto a new discovery. In 1945, about 35 years ago, government researchers realized that nitrates, commonly used to preserve color in meats,and other food additives,caused cancer. Yet, these carcinogenic additives remain in our food, and it becomes more difficult all the time to know which things on the packaging labels of processed food are helpful or harmful. The additives which we eat are not all so direct. Farmers often give penicillin to beef and living animals, and because of this ,penicillin has been found in the milk of treated cow. Sometimes similar drugs are given to animals not for medical purposes,but for financial reasons. The farmers are simply trying to fatten the animals in order to obtain a higher price on the market. Although the Food and Drug Administration(FDA) has tried repeatedly to control these procedures, the practices continue.
What are nitrates used for?a.They preserve flavor in packaged foods.
b.They preserve the color of meats.
c.They are the objects of research.
d.They cause the animals to become fatter.答案：B解析： -

Passage 2
The food we eat seems to have profound effects on our health. Although science has made enormous steps in making food more fit to eat, it has, at the same time, made many foods unfit to
eat. some research has shown that perhaps eighty percent of all human illness are related to diet and forty percent of cancer is related to the diet as well, especially cancer of the colon. Different cultures are more prone to contract certain illness because of the food that is characteristic in these cultures.
That food related to illness is not a new discovery. In 1945, government researchers realized that nitrates and nitrites, commonly used to preserve color in meats, and other food additives, caused cancer. Yet, these carcinogenic additives remain in
our food, and it becomes more difficult all the time to know which things on the packaging labels of processed food are helpful or harmful.
The additives which we eat are not all so direct. Farmers often give penicillin to beef and poultry, and because of this, penicillin has been found in the milk of treated cow. Sometimes similar drugs are administered to animals not for medicinal purposes, but for financial reasons. The farmers are simply trying to fatten the animals in order to obtain a higher price on the market. Although the
Food and Drug Administration （FDA） has tried repeatedly to control these procedures, the practices continue.
It can inferred from the passage that___.A. Scientists have made all the food fit to eat.
B. Only in recent years have people found that the food is related to one’s illness.
C. All kinds of cancer are related to the diet.
D. Some additives are harmful to our health.答案：D解析： -

第二篇
Are These Food Safe to Eat?
Traditionally,in plant breeding,there are crossing varieties of the same species in ways they could cross naturally.For example,disease-resistant varieties of wheat have been crossed with highyield wheat to combine these properties.This type of natural gene exchange is safe and fairly predictable.
Genetic engineering(GE)makes it possible to exchange genes between unrelated species that cannot exchange genes with each other in a natural way.GE can involve the exchange of genes be-tween vastly different species一e.g. putting scorpion toxin genes into maize or fish antifreeze genes into tomatoes.It is possible that a scorpion toxin gene,even when it is in maize DNA,will still get the organism to produce scorpion toxin一but what other effects may it have in this alien environment? We have already realized this problem一adding human growth hormone genes to pigs certainly makes them grow一but it also gives them arthritis and makes them cross-eyed,which was entirely out of expectation.
It won't be difficult to find out,for example,that the gene for human intelligence will not have the same effect if it is inserted into cabbage DNA as it had in human DNA一but what side-effect would it have?In other words,is genetically modified(GM)food safe to eat?The answer is that no-body knows because long-term tests have not been carried out.
Those companies who want a GM product approved in the UK or USA are required to provide regulatory bodies with results of their own safety tests.Monsanto's soya beans were apparently fed to fish for 10 weeks before being approved.There was no requirement for independent testing,for longterm testing,for testing on humans or testing for specific dangers to children or allergic people.
The present opinion of the British Government is that"There is no evidence of long-term dangers from GM foods."In the US,the American Food and Drug Administration is now being prosecuted for covering up research that suggested possible risks from GM foods.Which statement about GM product is true according to the passage?
A:Adding human growth hormone genes to pigs does not make them grow.
B:The American Food and Drug Administration is now doing a research that suggested possible risks from GM foods.
C:The gene for human intelligence will not have the same effect if it is inserted into cabbage DNA as it had in human DNA.
D: There has been requirement for independent testing,for long-term testing,for testing on humans or testing for specific dangers to children or allergic people.答案：C解析：本题是细节判断题。题干是：哪种自然基因交换既安全又具有相当的可预见性？选B的依据是第一段第一句和最后一句：" Traditionally , in plant breeding , there are crossing varieties of the same species in ways they could cross naturally.""This type of natural gene exchange is safe and fairly predictable.”传统的植物培育方法，是依照植物自然杂交的方式进行相同物种的人工杂交。这种自然的基因交换既安全，又具有相当的可预见性。这说明选项B, 传统植物培育中的自然基因交换，是正确答案。
本题是细节考查题。题干是：根据原文，如下关于转基因产品的说法哪个是正确的？选C的依据是第三段第一句："…… for example , that the gene for human intelligence will not have the same effect if it is inserted into cabbage DNA as it had in human DNA.”例如，人类的智力基因在人体DNA内和注入卷心菜DNA后的作用是不同的。所以选项C符合题目要求，是正确答案。
本题是细节推理题。题干是：根据原文能推断出如下哪个句子？选D的依据是第二段和第四段的最后一句："… which was entirely out of expectation." " There was no requirement for independent testing,for long一term testing,for testing on humans or testing for specific dangers to children or allergic people.”而这一切是完全无法预测的。目前，尚无要求对转基因产品进行独立测试、长期测试、人体测试，或者就其对儿童或过敏者所造成的特定危险进行测试。选项D，基因工程有时有危险且难以预测，是对原文这两个事实的总结，是正确答案。
本题是细节判断题。题干是：作者可能持有的对于转基因产品的态度是什么？选B的依据是：作者在文中用来说明的事实通常和基因工程的危险和不确定性相关，所以选项B，拒绝的，是正确答案。
本题考查对于后文内容的预判能力。题干是：以下对文章的阐述哪个是正确的？选A的依据是全文第四段的第一句：" Those Companies who want a GM product approved in the UK or USA are required to provide regulatory bodies with results of their own safety tests.”在英国或者美国，如果一个公司希望其转基因产品获得批准，它必须向管理机构提供本公司转基因产品安全测试的结果。这与选项A中谈到的内容相符：如果一个公司能向管理机构提供本公司转基因产品安全测试的结果，就能从英国或美国获得转基因产品的许可。 -

Food Poisoning
Food sometimes gets poisoned with harmful things,A person who eats such food can get an illness called
food poisoning. Food poisoning is usually not serious,but some types are deadly.The symptoms of food poi-
soning usually begin within hours of eating the poisoned food.Fever is one of the most common symptoms.
Certain microorganisms（微生物）cause most types of food poisoning. Bacteria and other microorganisms
can poison eggs,meat,vegetables,and many other foods.After entering the body,these tiny living things re-
lease（释放）poisons that make people sick.
Some chemicals can also cause food poisoning. They are often added to food while it is being grown,pro-
cessed,or prepared.For example,many farmers spray chemicals on crops to kill weeds and insects.Some
people may have a bad reaction to those chemical、when they eat the crops.
Some plants and animals contain natural poisons that are harmful to people.These includo certain kinds
of seafood,grains,nuts,seeds,beans,and mushrooms.
When people handle food properly,the risk of food poisoning is very small.Microorganisms multiply rapidly
in dirty places and in warm temperatures.This means that people should never touch food with dirty hands or
put food on unwashed surfaces.Food should be kept in a refrigerator to stop microorganisms from growing,
Meat needs to be cooked thoroughly to kill any dangerous microorganisms. People should also wash food covered
with chemicals before eating it.Finally,people should not eat wild mushrooms or other foods that grow in the
wild.Some of these foods may contain natural materials that are poisonous to humans.In addition,some types
of fish can be poisonous.
Most people recover from food poisoning after a few days of resting and drinking extra water. If people
eat natural poisons,they must go to the hospital right away to have their stomachs emptied.
A:are always accompanied by a fever
B:are too common to be noted
C:can be noticed within hours
D:can he ignored答案：C解析：该题目考查关于食物中毒的描述。通读全文，可知第一段对食物中毒做了一个简单的 介绍。由第一段第三句“食物中毒通常并不严重，但有些也是致命的”可知D选项表述与原文 一致，B选项“食物中毒就意味着死亡”太绝对，与原文表述不符。从该段第四、五句可知食物 中毒会有很多的症状，最常见的是发烧，由此可知A选项表述正确。从第二段第一句可知食物 中毒也有很多种类，因此C选项表述与原文一致。据此分析，表述错误的只有B选项，因此为正确答案。
根据题目中关键词symptoms迅速定位至第一段最后两句话“食物中毒的症状往往在吃 完食物数小时内就会出现、发烧是最常见的一个症状。”由此可知，A选项表述与原文不一致， C选项表述与原文相符。B、D选项未提及。因此止确答案为C。
该题目考查引起食物中毒的原因。通读全文可知第二段至第四段讨论了什么东西会 引起食物中毒——微生物、化学制品及一些含有天然毒素的植物和动物。C 、A、D兰个选项分 别与之对应。而由第五段“Food should be kept in a refrigerator to stop microorganisms from growing." 可知low temperature、不会导致food poisoning。因此正确答案为B。
根据题目可迅速定位到第五段，由文中的“肉类需彻底烹调以杀灭有毒的微生物。覆 盖有化学物质的食物食用前要清洗：最后，人们不应该吃野生蘑菇或其他野生食物……”可以 推测出D选项表述正确。而A选项表述太绝对，B、C选项则无细节支持。
通读全文可知该篇文章讨论了食物中毒的症状、原因及如何降低食物中毒的风险。由 第五段第一句和最后一段可推测出C选项表述与原文意思相符，D选项表述错误。由第四段 可知天然物质也会引起食物中毒，因此A选项与原文表述不一致。B选项文中未提及。据此 分析正确答案为C。第二篇 本文主要介绍了核辐射危害的严重性、潜伏性和长期性。 -

A:to
B:with
C:for
D:about答案：C解析：eating habit是固定搭配，意为“饮食习惯”，句子的意思是：在过去的十年里，特别是年轻人意识到了改变饮食习惯的必要。taste：口味；method：方法；preference：偏爱。意思都不合适，所以A正确。
词汇搭配题，四个选项中只有for和good搭配，表示“有利于”，即加工过的食品不利于健康。其他三个介词意思都不合适。
从上下文来看，指人们对天然食物产生了兴趣。desire：欲望；attention:注意，关注；importance：重要性。这几个词都不合题意，因此选D。
即不含化学添加剂的食物。include：包括；hold：持有（观点）；involve：卷入，涉及。几个词和文章内容不符。所以答案为C。
这里指食物未受到化肥的影响。intervene：干预；interfere：干涉；disturb: 干扰。三个词和上下文意思不符。
in simple terms意为“简单地说”，属于固定搭配，其他意思不合适。phra-ses，短语：words：单词：language：语言。
句子意思是“土壤得到植物没有吸收的营养（nourish)”。 cultivate：栽培、培养；supply：供给、提供；fed是动词feed的过去式，意思是喂养。它们都不符合句子意思。
这是一个非限定性定语从句，用which引导，指代前面提到的情况，所以选C最合适。
本句提到这一方法的主要目的是增加食物的数量，显然此处在谈论目的，所以purpose合适。result：结果；plan：计划；idea：主意。
根据题意，这里指增加食物的数量，而不是（提高）质量，应该选D, sum和 total都有“总数”的意思；weight：重量；plan：计划。这三个词都不合适。
本句意思为“天然食物还包括那些允许自由进食及活动的动物”。 ask和 require：要求；order：命令。根据意思应该是允许而非命令或者要求动物进食，所以B正确。
pasture:牧场。这里指动物可以在良好的牧场上自由活动。farm：农场； mountains：山脉、山地；woods：森林。动物的天然栖息地应该在牧场，所以C正确。
这里指家禽的大批量生产，mass production是固定搭配。collective：集体的；amount：数量；large：大的。因此A正确。
本句意思是“这些鸡靠着比垃圾好不了多少的食物生存”,be fed on: 靠……生存，固定搭配。其他介词不合适。
前面一句提到在恶劣环境下喂养出来的鸡作为食物索然无味，可以想到这样的鸡产下的鸡蛋缺乏重要的营养。keep：保留；have：具有；need：需要。意思都不对，所以B正确。 -

The food we eat seems to have profound effects on our health.Although science has made enormous steps in making food more fit to eat ,it has, at the same time,made many foods unfit to eat. Some research has shown that perhaps eighty percent of all human illnesses are related to diet and forty percent of cancer is related to the diet as well,especially cancer of the colon. Different cultures are more likely to cause certain different illnesses because of the food that is characteristic in these cultures. That food is related to illness is nto a new discovery. In 1945, about 35 years ago, government researchers realized that nitrates, commonly used to preserve color in meats,and other food additives,caused cancer. Yet, these carcinogenic additives remain in our food, and it becomes more difficult all the time to know which things on the packaging labels of processed food are helpful or harmful. The additives which we eat are not all so direct. Farmers often give penicillin to beef and living animals, and because of this ,penicillin has been found in the milk of treated cow. Sometimes similar drugs are given to animals not for medical purposes,but for financial reasons. The farmers are simply trying to fatten the animals in order to obtain a higher price on the market. Although the Food and Drug Administration(FDA) has tried repeatedly to control these procedures, the practices continue. Which of the following statements is NOT ture?（）
- A、Drugs are always given to animals for medical reasons
