In a study on an animal model, researchers in Spain found that pigs (52) with 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 (53)The general down-regulation of leucocytes (54) by the Spanish researchers suggests an overall beneficial effect, a generally more healthy body.

About 10 percent of the starch (60) by human is resistant starch starch that is not digested in the small intestine and so is shunted into the large intestine (61) it ferments.

2017职称英语备考卫生b级完形填空练习(4)
2017 职称英语备考卫生 b 级完形填空练习(4)2017 年职称英语备考卫生 b 级完形填空练习How does it happen that children learn their mother tongue so well?When we compare them with adults learning a foreign language, we often find this interesting fact. A little child without knowledge or experience often succeeds in a complete mastery of the language. A grown-up person with fully developed mental powers, in most cases, may end up with a faulty and inexact command. What accounts for this difference?Despite other explanations,the real answer in my opinion lies partly in the child himself, partly in the behaviour of the people around him. In the first place, the time of learning the mother tongue is the most favourable of all, namely, the first years of life.A child hears it spoken from morning till night and, what is more important,always in its genuine form,with the right pronunciation, right intonation, right use of words and right structure. He drinks in all the words and expressions which come to him in a fresh. Ever- bubbling spring.There is no resistance: there is perfect assimilation.Then the child has, as it were, private lessons all the year round,while an adult language-student had each week a limited number of hours which he generally shares with others.The child has another advantage:he hears the language in all possible situations,always accompanied by the tight kind of gestures and facial expressions.Here there is nothing unnatural, such as is often found in language lessons in schools, when one talks about ice and snow in June or scorching heat in January. And what a child hears is generally what immediately interests him. Again and again,when his attempts at speech are successful,his desires are understood and fulfilled.Finally, though a child's "teachers" may not have been trained in language teaching,their relations with him are always close a personal. They take great pains to make their lessons easy.1. Compared with adults learning a foreign language, childrenlearn their native language with ease.A. RightB. WrongC. Not mentioned2.

注：第六篇为2013综合B真题，第8篇为2012年综合B真题，所以第7、9、10为复习重点。
其中第10篇为重中之重。
*第六篇 Teaching and learning 教与学Many teachers believe that the responsibilities for learning lie with the student. If a long reading assignment is given, instructors expect students to be familiar with the information in the reading even if they do not discuss it in class or take an examination. The ideal student is considered to be one who is motivated to learn for the sake of learning, not the one interested only in getting high grades. Sometimes homework is returned with brief written comments but without a grade. Even if a grade is not given, the student is responsible for learning the material assigned. When research is assigned, the professor expects the student to take it actively and to complete it with minimum guidance. It is the student's responsibility to find books, magazines, and articles in the library. Professors do not have the time to explain how a university library works; they expect students particularly graduate students to exhaust the reference sources in the library. Professors will help students who need it, but prefer that their students should not be too dependent on them. In the United Stats professors have many other duties besides teaching，such as administrative or research work. Therefore, the time that a professor can spend with a student outside of class is limited. If a student has problems with classroom work, the student should either approach a professor during office hours or make an appointment.*第七篇 The Difference between Man and Computer 人与电脑的区别What makes people different from computer programs? What is the missing element that our theories don’t yet account for? The answer is simple: People read newspaper stories for a reason: to learn more about what they are interested in. Computers, on the other hand，don't. In fact，computers don't even have interests; there is nothing in particular that they are trying to find out when they read. If a computer program is to be a model of story understanding，it should also read for a "purpose".Of course，people have several goals that do not make sense to attribute to computers. One might read a restaurant guide in order to satisfy hunger or entertainment goals, or to find a good place to go for a business lunch. Computers do not get hungry, and computers do not have business lunches.However，these physiological and social goals give rise to several intellectual or cognitive goals. A goal to satisfy hunger gives rise to goals to find information about the name of a restaurant which serves the desired type of food，how expensive the restaurant is，the location of the restaurant, etc. These are goals to acquire information or knowledge, what we are calling learning goals. These goals can be held by computers too; a computer might "want" to find out the location of a restaurant，and read a guide in order to do so in the same way as a person might. While such a goal would not arise out of hunger in the case of the computer，it might well arise out of the "goal" to learn more about restaurants.*第八篇 Look on The Bright Side看光明的一面Do you ever wish you were more optimistic, someone who always expected to be successful? Having someone around who always fears the worst isn’t really a lot of fun. We all know someone who sees a single cloud on a sunny day and says，"INooks like rain. " But if you catch yourself thinking such things，it's important to do something about it.You can change your view of life，accordingto psychologists. It only takes a little effort，and you'll find life more rewarding as a result. Optimism，they say，is partly about self-respect and confidence but it's also a more positive way of looking at life and all it has to offer. Optimists are more likely to start new projects and are generally more prepared to take risks. Upbringing is obviously very important in forming your attitude to the world. Some people are brought up to depend too much on others and grow up forever blaming other people when anything goes wrong. Most optimists，on the other hand, have been brought up not to regard failure as the end of the world—they just get on with their lives.*第九篇The First Bicycle 第一辆自行车The history of the bicycle goes back more than 200 years. In 1791，Count de Sivrac delighted onlookers in a park in Paris as he showed off his two-wheeled invention，a machine called the celeriferé. It was basically an enlarged version of a children’s toy which had been in use for many years. Sivrac's "celerifer é had a wooden frame，made in the shape of a horse，which was mounted on a wheel at either end. To ride it，you sat on a small seat，just like a modem bicycle，and pushed hard against the ground with your legs—there were no pedals. It was impossible to steer a celeriferé and it had no brakes，but despite these problems the invention very much appealed to the fashionable young men of Paris. Soon they were holding races up and down the streets.Minor injuries were common as riders attempted a final burst of speed . Controlling the machine was difficult，as the only way to change direction was to pull up the front of the "celeriferé" and turn it round while the front wheel was spinning in the air. "Celeriferés" were not popular for long，however，as the combination of no springs，no steering and rough roads made riding them very uncomfortable. Even so，the wooden celeriferé was the origin of the modem bicycle.*第十篇 Working Mothers 职业母亲Carefully conducted researches that have followed the children of working mothers have not been able to show any long-term problems，compared with children whose mothers stayed at home. My personal view is that mothers should be allowed to work if they wish. Whether we like it or not ，there are a number of mothers who just have to work.. There are those who have invested such a big part of their lives in establishing a career that they cannot afford see it lost. Then there are many who must work out of pure economic necessity. Many mothers are not cut out to be full-time parents. After a few months at home with a much loved infant ，they feel trapped and isolated.There are a number of options when it comes to choosing childcare. These range from child minders and nannies through to Granny or the kind lady across the street. In reality, however，many parents don't have any choice; they have to accept anything they can get. Be prepared! No matter how good the childcare may be，some children are going to protest wildly if they are left. This is a perfectly normal stage of child development. Babies separate well in the first six months，but soon after that they start to get a crush on Mum and close family members. Make sure that in the first week you allow plenty of time to help your child settle in.All children are different. Some are independent，while others are more attached to their mothers. Remember that if you want to do the best for your children，it's not the quantity of time you spend with them，it's the quality that matters.。

People around the globe hit the height of their misery and depression in middle 1 , a newntemational study suggests. The finding by British and American researchers was based on ananalysis of well-being among approximately 2 million people in 80 nations. With few exceptions,the observation appears to apply across the board, regardless 2 gender (性别), culture, geography, wealth, job history, education, and marriage or parental status."The scientific fact seems to be that happiness and positive mental health follow a giant 'U'3through life," said study author Andrew J. Oswald, a professor of economics at WarwickUniversity in Warwickshire, England. "For the average person, it's high when you're 20, and then itslowly4and bottoms out in your 40s. But the good news is that your5health picks upagain, and eventually gets back to the high levels of your youth."The finding was 6 on the pooling of several different sources of happiness data,including: two multi-decade happiness/satisfaction surveys (first launched in the1970s), involvingabout 500,000 American and Western European men and women; four rounds of the 80-nation"WorldValues Survey" 7 between 1981 and xx in North America, Eastern and WesternEurope, Asia, Africa, Australia, and Central and South America; and a xx-xx survey 8nearly 1 million Britons.The bottom-line: For most people throughout the world, the highest probability for9strikingis around 44 years of age.In the United States, however, some as-yet unexplained 10differences were observed,with happiness among men dipping the most in their early 50s, whereas women hit their nadir (最低点 ) around the age of 40.The researchers cautioned that cheerful people tend to live longer than unhappy 11 – a fact that might have skewed (使偏斜) the overall finding. But they also suggested that evidence of a happiness 12might simply reflect a midlife choice to give up long-held but no longer tenable (守得住的) aspiration (志向 ) , followed by a senior's sense of gratitude for having suessfully endured 13 others did not."That said, some might fred it helpful simply to understand the general14of mental healthas they go through their own life," said Oswald.

参考答案：
51 C 在四个选项中,选项应该是resent （最近的） .如果用late ,则用latest 才更符合上下文意思：而last 则是排前后次序的问题；modern 更不合适。
52 D “健康长寿是社会环境的……,显然应该是”改善“而不应该是”进步“,因为社会环境没有”进步“”落后“之分,更不可能是”增加“、增长”了。
53 A 回答这道题首先要分析本句的语法关系。
work 在这里是作为及物动词使用的, what 引起的从句是它的宾语,在四个洗项中只有A、D 可与其构成及物动词,work sth. out意为“努力搞清楚”而work sth. off则是“清除”的意思,显然应该前者合适。
54 A 填空时要注意空白处后面有介词的from,四个选项中只有A 和B 后面可与from 搭配,learn sth. from 意为“从……中学到……”而gather sth. from 则是“从……中搜集到……”。
故只有A 项合适。
55 B 空白处后面有any changes 做它的宾语,从上下文可以很容易猜出,这里的意思应该是“做出某种改变”而make any changes 正好是表达这个意思的习惯用法,其他选项均不合适。
56 B 从语法上分析,从空白处起至句子结束应该是一个定语从句,作ingredient的定语。
定语从句缺一个主语,四个选项中只有B、C 可以考虑,显然只有that 才能代替ingredient.
57 D 空白处前面的形容词beneficial意思是“有益的”“对……有益”英语的表达方法就是“beneficial to…”其他选项均不合适。
58 C 从常识上我们可以很容易做出判断,“促使人口迅速老龄化的另一个因素”一定是“出生率的下降”其他选项均不合适。
59 A 短文谈的是长寿问题,从上下文也很容易猜出,life是正确答案。
60 D 本句的谓语是hsd doubled. 从上下文看,显然是指老年人口的“数量”（number）。
figure不是指“数量”而是指具体的某个“数字”,所以这里不合适。
61 C 此处显然是要说“面对经济问题”face a problem是习惯的表达方法；meet虽然也有“遇到”的意思,但那是太具体的“面对面相遇”英语也不习惯用它来表达“面对……问题”。
62 B 四个选项与look搭配,只有look after （照料、照顾）合适,其他look at （瞧、看）、look into （调查、了解）、look for （寻找）均不合适。
63 D 此处“提高退休年龄”还是用raise合适；lift虽然汉译中也有“使……升高”的意思,但那是太具体的“举起”,put 和move 就更不恰当了。
64 A “工作可以给老年人的生活带来一种责任感和使命感”这里的“……感”应该使用senes,英语中“责任感”“幽默感”“是非感”等习惯用sense；而feeling则主要用于冷、热、舒服、饥饿等具体的感觉；sentiment则是指“情操”、“思想感情”。
65 A “起一种……作用”使用play a…role是习惯的表达方法,其它选项都无法与其搭配。
