As a boy, Sanders was much influenced(影響) by books about the sea, but by the age of fifteen he had decided to become a doctor rather than a sailor. His father was a doctor. So he was often with the doctors and got along very well with them. When he was fourteen, he was already hanging around the hospital where he was supposed to be helping to clean the medicine bottles, but was actually trying to listen to the doctors’ conversations with patients in the next room.

During the war Sanders served in the army as a surgeon(外科醫(yī)生). “That was the happiest time of my life. I was dealing with real sufferers and on the whole making a success of my job.” In Rhodes he taught the country people simple facts about medicine. He saw himself as a life-saver. He had proved his skill to himself and had a firm belief that he could serve those who lived simply, and were dependent upon him. Thus, while in a position to tell them what to do he could feel he was serving them.

After the war, he married and set up a practice deep in the English countryside, working under an old doctor who hated the sight of blood. This gave the younger man plenty of opportunity(機會) to go on working as a life-saver.

1.When he was a small boy, books about the sea had made Sanders want to be ___.

A. a surgeon B. an army man

C. a sailor D. a life-saver

2.At the age of 14, Sanders ___.

A. worked as a doctor by cleaning the medicine bottles

Sometimes we can get so caught up in the stress and worry of our personal lives that our minds become too confused to operate effectively.This is especially dangerous in a test-taking situation.After hours of reading and studying,our brains can lock up in a state of overload.

In a stressful situation it's often a must to clear your mind completely to allow your brain to refresh itself and recalibrate all of its functions.But when you're tense,clearing your mind isn't so easy!Try this relaxation technique if you think your brain has seized up from information overload.

1.Set aside at least five minutes for quiet "clearing" time.If you're at school,see if you can put your head down somewhere or find an empty room or quiet space.If necessary,set a watch (or phone) alarm or ask a friend to tap you on the shoulder at a designated time.

2.Think of a time or place that puts you into a complete state of peace.This place will vary from person to person.Have you ever sat on the beach watching the waves come in and realized you've "zoned out" fora while?This is the sort of experience you're looking for.Other experiences that make us zone out could be: Sitting in the dark and staring at Christmas tree lights—remember how peaceful that feels?

3.Cover your eyes and go to your "place".If you are at school preparing for a test before class,you may simply rest your elbows on the desk and put your hands over your eyes.For some people,it may not be a good idea to put your head down.(You might fall asleep!)

Don't let any thoughts creep into your head.As soon as you start to think about a test problem,clear away the thought and concentrate on your peaceful place.

4.Snap out of it!Remember,this is not nap time.The point here is to refresh your brain.After five or ten minutes of clearing time,take a brisk walk or take a drink of water to re-energize your mind and body.Stay relaxed and resist the urge to think about the things that are stressing you out or clogging your brain.Don't let your brain go back to freeze-out.

Now go on with your test or study session refreshed and ready!

You are sitting on the desk. A teacher is writing on the blackboard. Kids are yelling in the playground outside. A book falls off the desk next to you. Suddenly, the teacher hands you a pop quiz.

Don’t panic! 1. You’re in a “virtual（虛擬的）classroom”. Everything you see and hear is coming to you through a computer-operated display that you’re wearing on your head like a pair of very big glasses.

Movie directors and video game producers have been using computers for years to create ever more realistic special effects. Some companies are now building three-dimensional（三維）fantasy worlds in which players, linked by computer networks, appear to meet and go on explorations together.

4. They see virtual reality technology as a useful tool for learning more about why people act as they do. It could help psychologists deter identify and come up with solutions for behaviors problems, for example.

科目：高中英語 來源：四川省瀘州市2017屆高三四診（臨考沖刺模擬）英語試卷（有答案） 題型：閱讀理解

A bite from a tsetse fly is an extremely unpleasant experience.To make matters worse,several species of tsetse fly can transmit diseases.One of the most dangerous is a parasite（寄生蟲）that causes "sleeping sickness".

After the initial bite,sleeping sickness symptoms often start with a fever,headaches and aching muscles.As the illness goes on,those infected become increasingly tired,which is where it gets its name.

It is worth noting that sleeping sickness is no longer as deadly as it once was.In the early 20th Century several hundred thousand people were infected each year.By the 1960s the disease was considered "under control" and had reached very low numbers,making its spread more difficult.But in the 1970s there was another major infection,which took 20 years to control.Since then,better screening programs and earlier treatments have reduced the number of cases dramatically.In 20is this figure dropped to fewer than 3,000.The World Health Organization (WHO) hopes the disease will be completely removed by 2020.More problematically,a series of new studies have shown that the parasite is more complicated than previously believed.

Sleeping sickness has always been considered—and analyzed—as a blood disease,because the parasites can readily be discovered in the blood of its victims.However,in a recent study found that the parasite can stay in the skin and fat,as well as in the blood.There may even be a higher density（密度）of the parasite in the skin than in the blood. That means a person can have no symptoms but still both harbor the disease and spread it.The finding could explain the mysterious 1970s infection,and why the disease can spring up in areas that had previously been cleared.

1.What's the danger of a tsetse fly bite?

A. It makes people sleepy. B. It causes skin disease.

C. It brings about deaths. D. It transmits deadly parasites.

2.What can we infer about sleeping sickness from Paragraph 3?

A. It's still a threat to human health. B. It's not that dangerous at present.

C. It's incurable in the early 20th century. D. It's completely under control in the 1960s.

3.What does the underlined "harbor" most probably mean?

A. carry B. resist C. exchange D. hide

4.What does the latest research indicate according to the passage?

A. Sleeping sickness is a blood disease. B. Skin is more suitable for the parasite to grow.

C. Sleeping sickness can be spread with no signs. D. Parasites in the skin caused the 1970s infection.
