3.CFood 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 poisoning 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 release(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, processed, or prepared. For example, many farmers spray chemicals on crops to kill weeds and insects. Some people may have a bad reaction to those chemicals when they eat the crops.Some plants and animals contain natural poisons that are harmful to people. These include 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.51. Which of the following statements is NOT true?A. Food when poisoned can make people sick.B. Food poisoning means death.C. Food poisoning comes in varieties.D. Food poisoning can be serious.

    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.

    According to the passage,killing insets and bacteria present in food by irradiating_________.
    A:has been completely approved by the FDA
    B:is being reviewed by the FDA
    C:is not completely approved by the U.S. government

    Some People do Not Taste Salt Like Others

    Low-salt foods may be harder for some people to like than others,according to a study by a Penn State
    College of Agricultural Sciences food scientist.The research indicates that genetic factors influence some of
    the difference in the levels of salt we like to eat.
    Those conclusions are important because recent,well-publicized efforts to reduce the salt content in food
    have left many people struggling to accept fare that simply does not taste as good to them as it does to others,
    pointed out John Hayes,assistant professor of food science who was lead investigator on the study.
    Diets high in salt can increase the risk of high blood pressure and stroke.That is why public health ex-
    perts and food companies are working together on ways to help consumers lower salt intake through foods that
    are enjoyable to eat.This study increases undersfanding of salt preference and consumption.
    The research involved 87 carefully screened participants who sampled salty foods such as soup and
    chips,on multiple occasions,spread out over weeks.Test subjects were 45 men and 42 women,reportedly
    healthy,ranging in age from 20 to 40 years.The sample was composed of individuals who were not actively
    modifying their dietary intake and did not smoke cigarettes.They rated the intensity of taste on a commonly
    used scientific scale,ranging from barely detectable to strongest sensation of any kind.
    "Most of us like the taste of salt.However,some individuals eat more salt,both because they like the
    taste of saltiness more,and also because it is needed to block other unpleasant tastes in food,"said Hayes.
    "Supertasters,people who experience tastes more intensely,consume more salt than nontasters do.Snack
    foods have saltiness as their primary flavor,and at least for these foods,more is better,so the supertasters
    seem to like them more."
    However,supertasters also need higher levels of salt to block unpleasant bitter tastes in food such as
    cheese,Hayes noted."For example,cheese is a wonderful blend of dairy flavors from fermented milk,but al-
    so bitter tastes from ripening that are blocked by salt,"he said."A supertaster finds low-salt cheese unpleasant
    because the bitterness is too pronounced."
    Hayes cited research done more than 75 years ago by a chemist named Fox and a geneticist named
    Blakeslee,showing that individuals differ in their ability to taste certain chemicals.As a result,Hayes ex-
    plained,we know that a wide range in taste acuity exists,and this variation is as normal as variations in eye
    and hair color.
    "Some people,called supertasters,'describe bitter compounds as being extremely bitter,while others,
    called nontasters,find these same bitter compounds to be tasteless or only weakly bitter,"he said."Response
    to bitter compounds is one of many ways to identify biological differences in food preference because super-
    tasting is not limited to bitterness."

    John Hayes points out that_________.
    A:food with less salt tastes better
    B:many people make efforts to accept low-salt food
    C:many people never eat low-salt food
    D:it is good to health to eat food without salt

    答案:B
    解析:
    由文章第二段可知,减少食物中的盐使许多口味重的人反对接受这种食物,选项中只 有“许多人努力接受低盐食物”符合题意。
    由第四段的内容可知,整段主要讲的是“怎样选择被测试者以及研究中他们该怎 么做”。
    由第五段的内容可知,口味超重的人特别喜欢快餐是因为快餐含盐比较多。
    由第六段的内容可知,含盐高的乳酪可以遮住其苦味,使其不那么苦,所以口味重的人 喜欢吃含盐高的乳酪。
    由最后一段的“biological differences”可以推断出人的口味是由其基因决定的。

  • 第12题:

    问答题
    In this section, there is one passage followed by a summary. Read the passage carefully, and then complete the summary below by choosing a maximum of three words from the passage to fill in each of the blanks. Remember to write the answers on the answer sheet.  Questions 1 to 5 are based on the following passage.  Everyone knows about pollution in the environment. Water, air, and land are all polluted. This means that pollution is everywhere. Now, scientists are looking inside our bodies to find out about internal pollution.  In 2003, the Environmental Working Group studied nine people to measure the chemicals in their bodies. These nine people had an average of 53 cancer-causing chemicals in their bodies. They also had an average of 62 chemicals that can damage the brain, and 55 that can harm babies in pregnant women. Even though a lot of chemicals were found in human bodies, the chemicals were found in small amounts. The amounts were small enough that they were probably not hurting the people. However, scientists are worried because most of these chemicals were created by humans. Most of these chemicals did not exist 75 years ago. This proves that we have not only polluted the world—we have polluted our own bodies!  How does this pollution get into our bodies? We come into contact with many chemicals every day. For example, everyone uses soap, skin lotion, and shampoo. However, few people know that these products contain harmful chemicals, some of which may cause memory loss. Chemicals known as DEA (diethanolamine) and TEA (triethanolamine) may seep into the skin and stop us from absorbing a helpful nutrient called “choline”. Choline is a nutrient that plays a crucial role in the memory cell making process in the developing brain. Some people worry that every time we wash our hair, we are decreasing our memories.  Everyone knows they should brush their teeth regularly, but recent research has shown that some toothpastes can cause cancer. Fluoride is a key ingredient in many toothpastes. However, studies show that fluoride does not really protect our teeth. In fact, fluoride has been connected with bone cancer and other diseases. While we are trying to save our smiles, we could be damaging our health.  Women are probably exposed to more chemicals than men because they use more beauty products. Recently, harmful chemicals have been found in nail polish, hair spray, deodorant, and perfume. The chemicals are called “phthalates”. Studies on animals have shown that phthalates can damage the liver, the kidneys, and the lungs. Cosmetic companies say the amounts of phthalates in their products are safe, but consumer protection groups disagree. They say some women use so many products that the levels are actually high. So, the more women try to look beautiful, the more they could be harming their health.  In a futuristic story by Ray Bradbury, a man found a pristine stream on a new planet. When he drank from the stream, he died! Why? His body was so polluted that pure water was a poison to him! Perhaps that is only science fiction, but it reminds us to take care of our bodies. We must find ways to reduce the pollution we absorb.  Summary:  Like our polluted environment, our bodies are no longer pollution-free. Scientists now know that there is pollution in our bodies. On  1 , we have 53 cancer-causing chemicals in our bodies. Even fluoride  2 with bone cancer and other diseases. Some common cosmetics contain small amounts of chemicals, which seep into our  3 when we use these products. They prevent us from absorbing the  4 our bodies need. So, it is  5 that we find ways to reduce the amount of chemicals in our bodies. We should remind our friends and families to take care of their bodies.

    正确答案:
    1.average 第二段中提到:2003年,环境工作组对九个人做了调查研究,其结果显示他们有an average of 53 cancer - causing chemicals in their bodies,这九个人代表了我们普通人群。
    2.has been connected / is connected 第四段倒数第二句明确提到In fact, fluoride has been connected with bone cancer and other diseases。
    3.skin 第三段以香皂、润肤露和洗发水等普通化妆品为例讲述了它们中含有的DEA和TEA “may seep into the skin…”,且由常识可知,化妆品直接与皮肤接触,使用过程中很容易渗透进皮肤,因此答案为skin。
    4.nutrients 第三段提到日用护肤品中含有的DEA和TEA may seep into the skin and stop us from absorbing a helpful nutrient called “choline”,由此类推,可知普通化妆品的使用会妨碍我们的身体吸收其所需要的营养物。nutrient营养物,滋养品。
    5.crucial 本文详细论述了化学物质会对我们的身体造成巨大的伤害,最后一句又提到我们必须想办法减少体内吸收的污染物,由此可知寻找减少我们体内的化学物质的方法是至关重要的。另外,答案还可以是important,essential等意义相近的词。

    D:Most consumers welcome the food processing companies outfitted with irradiated equipment.

    答案:D
    解析:
    推理判断题。本题考查对review一词的理解。从文章第一段第一句可知,有些经过辐射处理的食品已被FDA认可;从第二句的being reviewed可知有些食品仍然正在评估中。所以选项A、B、D都太绝对或概括过度,均不正确。
    推理判断题。本题考查对复合句的理解。本题解题的关键是找出第二段结尾句中的that引导的定语从句修饰的是process,从该定语从句可推断出消费者对其持不认同的态度。由此可见,选项D是本题的答案。选项A、几C在第二段中都先后有明确提及。
    词义推断题。根据上下文,特别是outfit和equipment两个词,可知是为 processing plants配备设备。因此,可推断出processing plants指的是“食品加工厂”。
    事实细节题。第三段指出食物在哪些情况下要贴上被辐射过的标签,其中第一句提到在supermarket一定要标明哪些食品被辐射过,但对医院或餐厅出售的食物并无此规定。选项D在文中没有提及。
    主旨大意题。第一段提到,FDA认可部分食品可以用辐射方法进行处理,第二段谈到消费者对irradiated food持怀疑态度,同时符合这两条的只有选项C。

    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.

    What does"processing plants"in the second paragraph most probably refer to?
    A:Market information processers.
    B:Food-processing factories.
    C:Business companies.
    D:Supermarket.

    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.

    From Paragraph 5,we can learn that_______________.
    A:mushrooms should not he eaten
