Since leaving___ school, the teen had been eating only French fries, Pringles and white bread, as well as a(n)___ slice of ham or a sausage. At the age of 14, feeling tired and not well, he was diagnosed with vitamin B12 deficiency(缺乏)and was___ supplements(补充剂), but he did not___ the treatment or improve his poor diet. Three years later, he was taken to the Bristol Eye Hospital because of progressive___ loss.

Dr Denize Atan, who___ him at the hospital, said, “The teenager explained this eating disorder as a dislike of certain textures of food that he really could not____, and so chips and crisps were really the only types of food that he wanted and felt that he could eat.”

__ in B12 as well as some other important vitamins and minerals, he was not over or underweight, but was____ malnourished (lacking nutrition) from his food intake disorder. “He had lost minerals from his bone, which was really quite___ for a boy of his age.”

In terms of his sight loss, he met the___ for being registered blind. Dr Atan said, “He can’t drive and would find it really difficult to____, watch TV or recognize faces. He can walk around on his own,____, because he doesn’t lose peripheral( 周 边 的 )vision.”

The condition the young man has is treatable___ diagnosed early. Left too long, however, the nerve fibers in the optic nerve die and the damage becomes____.

Dr Atan said vegans(素食主义者)are also at increased risk of B12 deficiency-related sight problems if they do not replace what they can lack when___ meat from their diet.

“Multivitamin tablets can supplement a diet, but are not a(n) ___ for eating healthily. It’s much better to___ vitamins through a varied and balanced diet,” she said, adding that too much of certain vitamins, including vitamin A, can be____, “so you don’t want to overdo it”.

Experts believe that there are about 40,000 different types of jobs in the world. Choosing the right one is a difficult job in itself.

“Finding a job” is not the same as “choosing a job”. Many young people end up in a job that they are not suited to. “Chance” may play a more important part than “decision”. So here are a few steps to help you think about jobs, which you might enjoy doing after school or university.

First, it is important to recognize what kind of person you are and which special qualities make you different from everyone else.

To examine your skills and abilities even further, ask yourself this question: in the following three areas — skills with people, skills with information or skills with things — which are your best skills?

You may have noticed something while you were doing this task. The point is that there is a difference between an interest and a skill. If you like are and enjoy looking at pictures, it is an interest. But if you can draw a horse that looks like a horse and not a big dog, that looks like a horse and not a big dog, that looks like a horse and not a big dog, that is a skill. The best job is one that uses your skills n something that you are interested in. in addition to this, it is an advantage if you believe that a particular job is worth doing in the world.

After that, the next step is research. To find out as much as possible about different kinds of work, go to the library and read books, magazines and newspapers. Ask your friends about the work they do. If you are interested in banking, it is better to talk to a bank clerk who is twenty –four, rather than a bank manager who is sixty –four. Do not rely on your parents’ friends for information. A younger person will be able to describe a normal day at work and tell you about the interesting or boring things when you first start working.

Finally, trust your own ideas and your own thinking! It is your own life, so find something that you enjoy doing.

61. The difference between “finding a job” and “choosing a job” lies in _______.

A. finding a job is a decision while choosing a job is a chance

B. finding a job is more important than choosing a job.

C. A job that you find is one who is more suitable for you than one that you choose

D. A job that you choose is based on your decision and suits you while one that you find often isn’t.

62. What is the first step to find a job that suits you well?

A. The first step is to recognize what kind of person you are and which special qualities make you different from everyone else.

B. The first step is to find out as much as possible about different kinds of work.

C. The first step is to ask your friends about the work they do.

D. The first step is to consider your parents’ advice.

63. All the things are ways of research about different kinds of work except______.

A. Go to library and refer to books.

B. Turn to your friends to help.

C. Turn to your parents’ friends for advice.

D. Talk to a younger person for information

64. If you are interested in banking, you should talk to a bank clerk who is twenty –four instead of a bank manager who is sixty –four because_________.

A. they will be able to describe a special day at work.

B. they are full-time workers and can tell you about the interesting or boring things at work.

C. it is easier to find a bank clerk than to find a bank manager.

D. they are easier to get along with

65. Where does the passage probably appear?

A .A textbook    B. A newspaper   C. A TV programme   D. A magazine

高三英语单项填空中等难度题查看答案及解析

Choose the yum(美味的东西) and risk the yuk（讨厌的东西）?

Scientists have given us a lot of health warnings. The advice from cancer experts for avoiding bowel(肠) cancer is "try to avoid processed(加工过的) meats such as bacon, ham, corned beef and some sausages", and women fearing breast cancer are told "there doesn't seem to be a starting point at which alcohol consumption is safe",

But all these health warnings tend to have little influence on behavior, So who is being unreasonable —the scientists who give us health advice, or the public that just ignores it?

The curious fact is that both might be right. The reasoning behind these health warnings seems to be this: if you do more of something pleasurable (which we shall give the name “yum”) there is a higher risk of something bad (which we shall give the name “yuk”)occurring, so you should avoid yum.

But when presented with this argument you might ask two questions.

First, maybe the pleasure of yum makes the risk worth taking, especially if yuk might occur a long time in the future? Second, maybe there are other benefits of yum that could cancel out the risks of the particular yuk that has been identified (确认) ?

So suppose bacon sandwiches are your particular yum: research shows that 50g per day — that is a great greasy sandwich — increases your risk of bowel cancer by 20%.

But this means that out of every 100 people who stuffed down that big bacon sandwich every day of their lives, the number of bowel cancers would rise from five to six.

In addition, if a middle-aged woman gave up alcohol, it might reduce her risk of breast cancer, but could increase risk of some other cancers as well as heart disease.

So we need to look at the whole picture before trying to get people to change what they do, since everything has benefit and harms — just think of the joggers(慢跑者) who get knocked down by cars — and people need to be able to find their own balance.

Therefore, as you reach for your yum, perhaps sometimes pause a moment and realize that you are taking a gamble(赌博) on the yuk occurring, but that it may be a risk worth taking.

1.What is the advice given by scientists for avoiding breast cancer?

A. Try to avoid processed meat. B. Try to avoid alcohol.

C. Try to choose the yum.           D. Try to risk the yuk.

2. What does “this argument” in Paragraph 4 mean?

A. If you choose the yum, you will risk the yuk.

B. If you risk the yuk, you’ll choose the yum.

C. The yum is worth taking, especially if yuk might occur in the future.

D. Other benefits of yum could cancel out the risks of the yuk.

3.Why do we need to look at the whole picture before trying to get people to change what they do?

A. Because giving up alcohol might reduce breast cancer.

B. Because people are not able to find their own balance.

C. Because all the things have both sides.

D. Because the advice given by scientists is not true.

4.According to the passage, which of the following is correct?

A. People are often influenced by the health warnings.

B. Both the scientists and the public are not reasonable.

C. Alcohol consumption has both benefit and harms.

D. People should avoid yum to reduce the risk of yuk.
