题目内容

People are overweight for many reasons, the most important one of which is that they eat the wrong foods, get the wrong types of calories per meal, and they also eat meals at the wrong time each day. Food is more powerful than any weight loss pill, because the food that you eat can either make you thin or fat. This is true because your body is like an engine, and it only needs certain foods at certain intervals(间隔) each day.

Low-calorie Diets Do Not Work

The reason people cannot lose weight by starving themselves is that their metabolism(新陈代谢) will detect any major drop in calories and it will then adjust itself by burning fewer calories each day. That is the reason why you can eat 1,000 calories per day and not lose any weight, while your friends can eat 2,500 calories per day and not gain any weight.

Low-fat Diets Do Not Work

Many people in today’s society are buying mostly low-fat or non-fat food at the grocery store. Everybody knows how much fat is inside the food they buy. However, people are getting fatter than ever before by doing this. They are not losing weight by changing to this low-fat lifestyle.

Losing weight has nothing to do with these things. One of the most important things you can do to control your weight is to eat the proper foods, such as fruit and vegetables, eat them at the right time, and exercise every day. If people make this a habit, they will lose weight.

1.What is the main reason why people are overweight?

A. They burn many calories every day.

B. They eat the wrong foods at the wrong time.

C. They eat food with lots of calories.

D. They don’t take weight loss pills.

2.The article is written in order to________.

A. tell readers not to buy low-fat or non-fat food.

B.tell readers about an important scientific discovery.

C .tell readers how to lose weight.

D. call on people to lose weight and stay healthy.

3.To realize the aim of your weight loss plan, you should_________.

a. do exercise every day

b. eat meals at the right time

c. eat fruits and vegetables

d. eat low-fat or sweet food

e. eat the proper foods at each meal

A. a, b, c, e B. a, b, d, e

C. a, c, d, e D.a, b, c, d

C “Over the years the unthinkable has become thinkable and today we sense we are close to being able to alter human heredity(遗传)．” These were the words of David Baltimore of the California Institute of Technology，on December 1st，when he opened a three?day meeting in Washington to discuss the morality and use of human gene editing．Dr Baltimore is an old hand at these sorts of discussions，for he was also a participant in the Asilomar conference，in 1975，which brought scientists together to discuss a safe way of using the then?new technology of recombinant DNA，and whose recommendations influenced a generation of biotechnology researchers．

Four decades on，the need for a similar sort of chin?wag has arisen．The International Summit on Human Gene Editing has been held by the national scientific academies of three countries—America，Britain and China．They are particularly concerned about whether gene editing should be used to make heritable changes to the human germ line，something Dr Baltimore described as a deep and troubling question．Like those of Asilomar，the conclusions of this meeting will not be binding．But the hope is that，again like Asilomar，a mixture of common sense and peer pressure will create a world in which scientists are trusted to regulate themselves，rather than having politicians and civil servants do it for them．The meeting is being held against a backdrop of rapid scientific advance．Since 2012 research into a new，easy?to?use editing tool called CRISPR?Cas9 has blossomed．This technique involves a piece of RNA (a chemical messenger，which can be used to recognise a target section of DNA) and an enzyme(酶) called a nuclease that can snip unwanted genes out and paste new ones in．

Public interest was aroused in April，when Chinese scientists announced they had edited genes in non?viable(无活力的) human embryos，and again in November when British researchers said they had successfully treated a one?year?old girl who had leukaemia(白血病)，using gene?edited T?cells．T?cells are part of the immune system that attack，among other things，tumour cells．The researchers altered T?cells from a healthy donor to encourage them to recognise and kill the patient's cancer，to make them immune to her leukaemia drug，and to ensure they did not attack her healthy cells．

In another recent development，a firm called Edit as Medicine，which is based in Cambridge，Massachusetts，has said it hopes，in 2017，to start human clinical trials of CRISPR?Cas9 as a treatment for a rare genetic form of blindness known as Leber congenital amaurosis(伯氏先天性黑蒙)．Though other companies are already testing gene?editing therapies，these employ older，clunkier forms of the technology that seem likely to have less commercial potential．Moreover，researchers at the Broad Institute，also in Cambridge，said this week that they had made changes to CRISPR?Cas9 which greatly reduce the rate of editing errors—one of the main obstacles to the technique's medical use．

On the subject of germ?line editing，Eric Lander，the Broad's head，told the meeting it would be useful only in rare cases and said it might be a good idea to “exercise caution” before making permanent changes to the gene pool．The need for caution is advice that might also be heeded by those pursuing work in animals other than people，and in plants—subjects not being covered by the summit．

1.Which of the following is TRUE about CRISPR?Cas9?

A．It has fewer side effects．

B．It can modify human gene．

C．It can protect immune system．

D．It has less commercial potential．

2.The underlined word “chin?wag” in Paragraph 2 can be replaced by ________．

A．discussion

B．negotiation

C．argument

D．comparison

3.What can be inferred from the passage?

A．Dr．Baltimore started his research on modifying gene in 1975．

B．Scientists' opinions about the use of gene editing are consistent．

C．CRISPR?Cas9 has been applied to cure Leber congenital amaurosis．

D．More research should be made before the technology comes into wide use．

4.This passage is most probably a ________．

A．science fiction

B．scientific report

C．conference summary

D．commercial advertisement

Some people think that as more and more people have televisions in their homes, fewer and fewer people will buy books and newspapers. Why read an article in the newspaper, when the TV news can bring you the information in a few minutes and with pictures? Why read the life story of a famous man, when a short television program can tell you all that you want to know?

Television has not killed reading, however. Today, newspapers sell in very large numbers. And books of every kind are sold more than ever before. Books are still a cheap way to get information and enjoyment. Although some books with hard covers are expensive, many books are printed today as paperbacks (平装本), which are quite cheap. A paperback collection of short stories, for example, is always cheaper than an evening at the cinema or the theater, and you can keep a book for ever and read it many times.

Books are a wonderful provider of knowledge and pleasure and some types of books should be in every home. Every home should have a good dictionary. A good encyclopedia, though expensive, is useful, too, because you can find information on any subject. Besides, you can have such books as history books, science textbooks, cookbooks, and collections of stories and poems. Then from time to time you can take a book of poems off your shelves and read the thoughts and feelings of your favorite poets.

1. It can be inferred from the passage that ________.

A. TV programs are a chief provider of knowledge

B. cinemas are the best choice in getting information

C. reading is a cheap way of learning and having fun

D. newspapers are an expensive way to enjoy oneself

2.What does the sentences “Television has not killed reading, however” underlined in the second paragraph suggest?

A. People only need reading, though.

B. Reading is still necessary today.

C. Reading is more fun than television.

D.Watching television doesn’t help reading.

3.Which of the following is mainly discussed in the last paragraph?

A. Types of books

B. Kinds of dictionaries.

C. Lists of history books.

D. Collections of stories and poems.

The Importance of Accessibility Awareness

At a recent Teen Leadership of Jewish Family Services meeting, people with disabilities talked about their lives. 1. However, what amazed me most was the great importance of education about handicap accommodations (残疾人便利设施).

One school-teacher who is blind, and a woman who has used a wheelchair all her life are two important members of the National Group for Disabled Persons, devoted to raising awareness about disabilities. 2. These include handicap parking spots, handrails, and wheelchair ramps. One big concern is the people who take advantage of aids, such as handicap parking spaces. 3. And the meeting focused on educating the public.

Some handicap spots have extra room next to them, marked with the “No Parking” signs. “As long as I'm not in the spot, I can take the no-parking area next to it,” some people say. However, the woman who uses a wheelchair disagrees to this. The space exists to allow someone in a wheelchair to have room to get in or out of their car. 4.

Some walkways have handrails next to them to help those who require extra assistance. Whether it is a blind person seeking guidance or an elderly person seeking support, the rail is there for walking. Sometimes the rail is blocked, by a parked bicycle for instance, and consequently made useless. 5. People who are informed of the rail’s use would be less likely to mistake it for a bike rack.

Meeting some of the people who are affected by the lack of education about accommodations made me see that there is work to be done. If more people were educated about the proper uses of accommodations, there would be fewer challenges for people with physical disabilities.

A. Accommodations will vary according to the needs of the disabled.

B. As with the parking spot, this is more likely a case of lack of education.

C. They educate about all the accommodations for people with disabilities.

D. Improvement must be made so that disabled people can fully participate.

E. If there is a car in that space, the handicap parking spot is no longer useful.

F. So people without disabilities need to be educated about these accommodations.

G. I was amazed to hear about the challenges faced by people with physical disabilities.

Enough “meaningless drivel”. That’s the message from a group of members of the UK government who have been examining how social media firms like LinkedIn gather and use social media data.

The House of Commons Science and Technology Committee’s report, released last week, has blamed firms for making people sign up to long incomprehensible legal contracts and calls for an international standard or kitemark (认证标记) to identify sites that have clear terms and conditions.

“The term and conditions statement that we all carelessly agree to is meaningless drivel to anyone,” says Andrew Miller, the chair of the committee. Instead, he says, firms should provide a plain-English version of their terms. The simplified version would be checked by a third party and awarded a kitemark if it is an accurate reflection of the original.

It is not yet clear who would administer the scheme, but the UK government is looking at introducing it on a voluntary basis. “we need to think through how we make that work in practice,” says Miller.

Would we pay any more attention to a kitemark? “I think if you went and did the survey, people would like to think they would,” says Nigel Shadbolt at the University of Southampton, UK, who studies open data. “We do know people worry a lot about the inappropriate use of their information.” But what would happen in practice is another matter, he says.

Other organisations such as banks ask customers to sign long contracts they may not read or understand, but Miller believes social media requires special attention because it is so new. “We still don’t know how significant the long-term impact is going to be of unwise things that kids put on social media that come back and bite them in 20 years’ time,” he says.

Shadbolt, who gave evidence to the committee, says the problem is that we don’t know how companies will use our data because their business models and uses of data are still evolving. Large collections of personal information have become valuable only recently, he says.

The shock and anger when a social media firm does something with data that people don’t expect, even if users have apparently permission, show that the current situation isn’t working. If properly administered, a kitemark on terms and conditions could help people know what exactly they are signing up to. Although they would still have to actually read them.

1. What does the phrase “ meaningless drivel” in paragraphs 1 and 3 refer to?

A. Legal contracts that social media firms make people sign up to.

B. Warnings from the UK government against unsafe websites.

C. Guidelines on how to use social media websites properly.

D. Insignificant data collected by social media firms.

2.It can be inferred from the passage that Nigel Shadbolt doubts whether _______.

A. social media firms would conduct a survey on the kitemark scheme

B. people would pay as much attention to a kitemark as they think

C. a kitemark scheme would be workable on a nationwide scale

D. the kitemark would help companies develop their business models

3. Andrew Miller thinks social media needs more attention than banks mainly because _______.

A. their users consist largely of kids under 20 years old

B. the language in their contracts is usually harder to understand

C. the information they collected could become more valuable in future

D. it remains unknown how users’ data will be taken advantage of

4.The writer advises users of social media to _______.

A. think carefully before posting anything onto such websites

B. read the terms and conditions even if there is a kitemark

C. take no further action if they can find a kitemark

D. avoid providing too much personal information

5. Which of the following is the best title of the passage?

A. Say no to social media?

B. New security rules in operation?

C. Accept without reading?

D. Administration matters!
