1、2014年教材电子版 b级 阅读理解部分 第17-33篇17 eating potatoes gives your immune system a boosteating potatoes is not only good for bowel health,but also for the whole immune system, especially when they come in the form of a potato salad or eaten cold. in a study on an animal model,researchers in spain found that
2、pigs fed large quantities of raw potato starch (rps)1 not only had a healthier bowel, but also decreased levels of white blood cells, such as leucocytes and lymphocytes in their blood. white blood cells are produced as a result of inflammation or disease, generally when the body is challenged.the ge
3、neral down-regulation of leucocytes observed by the spanish researchers suggests an overall beneficial effect, a generally more healthy body.2 the reduction in leucocyte levels was about 15 percent. lower lymphocyte levels are also indicative of reduced levels of inflammation but the observed reduct
4、ion in both lymphocyte density and lymphocyte apoptosis is surprising.in what was the longest study of its kind,pigs were fed rps over 14 weeks to find out the effect of starch on bowel health. the use of raw potato starch in this experiment is designed to simulate the effects of a diet high in resi
5、stant starch, ” said study leader jose francisco perez at the universitat autonoma de barcelona3,spain.humans do not eat raw potatoes,but they do eat a lot of foods that contain resistant starch, such as cold boiled potatoes,legumes,grains,green bananas,pasta and cereals. about 10 percent of the sta
6、rch eaten by human is resistant starch 一 starch that is not digested in the small intestine and so is shunted into the large intestine where it ferments. starch consumption is thought to reduce the risk of large bowel cancer and may also have an effect on irritable bowel syndrome (ibs)4.immunology e
7、xpert lena ohmans team previously found that the overall lymphocyte levels do not vary for ibs patients, but that lymphocytes are transferred from the peripheral blood to the gut, which support the hypothesis of ibs being at least partially an inflammatory disorder. she says the decrease in lymphocy
8、tes observed by the spanish is therefore interesting, and a diet of resistant starch may be worth trying in ibs patients. ohman is currently at the department of internal medicine, goteborg university, sweden5. the study is published in the journal chemistry and industry, the magazine of the sci6. 词

32、但却并不知道体育锻炼的重要性。19 prolonging human lifeprolonging human life has increased the size of the human population. many people alive today would have died of childhood diseases if they had been born 100 years ago. because more people live longer, there are more people around at any given time. in fact, it
33、 is a decrease in death rates, not an increase in birthrates, that has led to the population explosion.prolonging human life has also increased the dependency load. in all societies, people who are disabled or too young or too old to work are dependent on the rest of society to provide for them. in
34、hunting and gathering cultures, old people who could not keep up might be left behind to die. in times of famine, infants might be allowed to die because they could not survive if their parents starved, whereas if the parents survived they could have another child. in most contemporary societies, pe
35、ople feel a moral obligation to keep people alive whether they can work or not. we have a great many people today who live past the age at which they want to work or are able to work; we also have rules which require people to retire at a certain age. unless these people were able to save money for
36、their retirement, somebody else must support them. in the united states many retired people live on social security checks which are so little that they must live in near poverty. older people have more illness than young or middle-aged people; unless they have wealth or private or government insura
37、nce, they must often go on welfare if they have a serious illness.when older people become senile or too weak and ill to care for themselves, they create grave problems for their families. in the past and in some traditional cultures, they would be cared for at home until they died. today, with most
38、 members of a household working or in school, there is often no one at home who can care for a sick or weak person. to meet this need, a great many nursing homes and convalescent hospitals have been built. these are often profit-making organizations, although some are sponsored by religious and othe
39、r nonprofit groups. while a few of these institutions arc good, most of them are simply dumping grounds for the dying in which care is given by poorly paid, overworked, and under-skilled personnel.词汇:dependency n.依赖性contemporary .现代的obligation n. 义务insurance n. 保险welfare n.福利senile dj. 衰老的grave dj.
40、严肃的convalescent dj.康复的sponsor v. 发起,资助institution n. 机构注释:1. prolonging human life has increased the size of the human population:延长人类生命的结果使得人口的数量有了增加。句中的 prolonging human life是动名词短语。由动名词短语作句子的主语时,句中动词必须用单数形式。如 : collecting stamps is his hobby.2. many people alive today would have died of childhood
41、diseases if they had been born 100 years ago:如果今天活着的很多人生于一百年以前,他们会死于各种儿童疾病。3. because more people live longer, there are more people around at any given time:因为有更多的人寿命更长,所以在任何一个特定的时间里的人也就更多。4. the dependency load: 抚养人口数量。5. in times of famine: 在饥荒年代6. go on welfare : 靠福利救济go on 有许多意思,其中的一个意思是依靠过活。例:
42、many people go on welfare when jobs become scarce.(工作难找时,许多人靠政府救济金过日子。)7. grave problems: 严重的问题8. convalescent hospitals: 康复医院;疗养院9. profit-making organizations: 赢利机构10. dumping grounds: 垃圾场练习:1. the writer believes that the population explosion results froma an increase in birthrates.b the industri
43、al development.c a decrease in death rates.d cultural advances.2. it can be inferred from the passage that in hunting and gathering culturesa it was a moral responsibility to keep old-aged people alive.b infants could be left dead in times of starvation.c parents had to impart the cultural wisdom of
44、 the tribe to their children.d death was considered to be freedom from hardships.3. according to the passage, which of the following statements about retired people in the united states is true?a many of them have a very hard life.b they cannot live a decent life without enough bank savings.c they r
45、ely mainly on their children for financial support.d most of them live with their children and therefore are well looked after.4. in paragraph 3, the phrase this need refers toa the need to prolong the lives of old people.b the need to enrich the life of the retired people.c the need to build profit

47、tes, not an increase in birthrates, that has led to the population explosion. 事实上,是由于死亡率的下降,而不是出生率的上升,导数了人口爆炸。2. b 第二段第四句说: in times of famine, infants might be allowed to die because they could not survive if their parents starved, whereas if the parents survived they could have another child. 在灾年,
48、可能会容忍婴儿死亡,因为,如果他们的父母饿死了,他们也无法生存,而如果父母生存下来可重新生儿育女。因此,选项 b是正确的答案。3. a 第二段倒数第二句是这么说的:in the united states many retired people live on social security checks which are so little that they must live in near poverty. (在美国,许多退休人员依靠社会保障金生活,其数额之小差不多使人穷困潦倒。)可以看出,在美国许多退休人员的生活是很艰难的。这正是选项a表达的意思,因而选项a是正确的答案。4. d
49、第三段第三句:today, with most members of a household working or in school, there is often no one at home who can care for a sick or weak person. (当今,由于家庭中大多数人都出去工作或上学,家里常常没有人来照顾有病或虚弱的人。)this need 出现在下面这个短语中:to meet this need(为了满足这种需要),它指句子前面的care for a sick or weak person。这正是选项d表达的意思。5. d文章昀后一句说 : most of
50、 them are simply dumping grounds for the dying in which care is given by poorly paid, overworked, and under-skilled personnel.大多数机构只不过是倾倒垂死的人的垃饭场,所谓的照顾都是由收入低、超量工作、技术水平低下的人员提供的。作者如此措辞显然是对大多数机构的强烈批评。因此,选项 d是正确答案。20 fda: human, animal waste threatens producethe biggest food safety risk for fresh fruits
51、 and vegetables as they are grown, picked or processed comes from human and animal waste, the u. s. food and drug administration (fda).said friday.more than 9, 000 americans die each year from food-borne diseases and some scientists believe fresh produce is the biggest carrier of contamination.the f
