Almost everyone suffers from a headache sometimes.But some people suffer from repeated, frequent headaches.
What is headache? What causes it? What can be done about a headache? What research is being done on headaches?
The dictionary defines(下定义) headache simply as “a pain in the head.” What most people mean by headache is a pain which lasts several minutes or hours.It covers the whole head, or one side of it, or perhaps the front or the back of the head.To add to the confusion(困惑) about a definition, some people call tight feeling in the head a headache.
A headache is important because it can be the first warning of a serious condition which probably could be controlled if discovered early.If a person removes the warning, day after day, with a pain-killer, he may pass the point of easy control.
The professional name for covering up a symptom(症状) is “masking” (遮蔽).A headache specialist once said, “Masking symptoms is not the best way of treatment.” He compared taking a pain-killer for a headache before a cause is known with taking iron pills for anemia(贫血症) while bleeding continues undiscovered.He added, “Sometimes it is wiser to stand still than to advance in darkness.
A headache is important also because it affects normal, happy living.The employee with a headache does less work.In a flash of temper he may upset his fellow workers or customers, causing a direct or indirect loss to his organization.The mother with a headache suffers and disturbs the family.She upsets her husband and children.

C.Headache may last several minutes or hours.

B.you’d better do nothing before you know how to deal with it
C.you’d better still stand there without moving when it is dark at night

A popular saying goes, “Sticks and stones may break my bones, but words will never hurt me.” However, that’s not really true. Words have the power to build us up or tear us down. It doesn’t matter if the words come from someone’s else or ourselves --- the positive and negative effects are just as lasting.

We all talk to ourselves sometimes. We’re usually too embarrassed to admit it, though. In fact, we really shouldn’t be because more and more experts believe talking to ourselves out loud is a healthy habit.
This “self-talk” helps us motivate ourselves, remember things, solve problems, and calm ourselves down. Be aware, though, that as much as 77% of self-talk tends to be negative. So in order to stay positive, we should only speak words of encouragement to ourselves. We should also be quick to give ourselves a pat on the back. The next time you finish a project, do well in a test, or finally clean your room, join me in saying “Good job!”
Often, words come out of our mouths without us thinking about the effect they will have. But we should be aware that our words cause certain responses in others. For example, when returning an item to a store, we might use warm, friendly language during the exchange. And the clear will probably respond in a similar manner. Or harsh and critical language will most likely cause the clerk to be defensive.
Words possess power because of their lasting effect. Many of us regret something we once said. And we remember unkind words said to us! Before speaking, we should always ask ourselves: Is it loving? Is it needed? If what we want to say doesn’t pass this test, then it’s better left unsaid.
Words possess power: both positive and negative. Those around us receive encouragement when we speak positively. We can offer hope, build self-esteem and motivate others to do their best. Negative words destroy all those things. Will we use our words to hurt or to heal? The choice is ours.
The main idea of the first paragraph is that ________.

A.words have a lasting effect on us
B.inspiring words give us confidence
C.negative words may let us down
D.not sticks and stones but words will hurt us

There is no sense for us to feel embarrassed when we talk to ourselves because _______.

A.almost everybody has the habit of talking to themselves
B.talking to ourselves always gives us courage
C.we can benefit from talking to ourselves
D.it does no harm to have “self-talk” when we are alone

The underlined part in the third paragraph means that we should also timely _______.

A.remind ourselves B.praise ourselves
C.make ourselves relaxed D.give ourselves amusement

The author would probably hold the view that ___________.

A.encouraging words are sure to lead to kind offers
B.negative words may stimulate us to make more progress
C.people tend to remember friendly words
D.it is better to think twice before talking to others

To get an extra 14 years of life, don't smoke, eat lots of fruits and vegetables, exercise regularly and drink alcohol in a proper amount.That is according to a study published this Monday in the Public Library of Science Medicine Journal.
After tracking more than 20,000 people aged 45 to 79 years in the United Kingdom from about 1993 to 2007, Kay-Tee Khaw of the University of Cambridge and his colleagues found that people who adopted these four healthy habits lived all average of 14 years longer than those who didn't.
“We've known for a long time that these behaviors are good things to do, but we've not seen this benefit before, ”said Susan Jebb, head of Nutrition and Health at Britain's Medical Research Council.“The benefit was also seen regardless of whether or not people were fat and what social class they came from.”
Study participants scored a point each for not smoking, regular physical activity, eating five servings of fruits and vegetables a day and moderate alcohol intake.
Public health experts said they hoped the study would inspire governments to introduce policies helping people to adopt these changes.But because the study only observed people rather than testing specific changes, it would be impossible to conclude that people who suddenly adopted these healthy behaviors would surely gain 14 years.
“We can't say that any person could gain 14 years by doing these things, ”said Dr.Tim Armstrong, a physical activity expert at the World Health Organization.“The 14 years is an average across the population of what's theoretically(理论上地)possible.”
“Most people know that things like a good diet matter and that smoking isn't good for them, ”Susan Jebb said.“We need to work on providing people with much more practical support to help them change.”
Which of the following DOESN'T belong to the four healthy habits?

A.Eat five servings of fruits and vegetables a day.
B.Do proper exercise in the morning every day.
C.Drinking alcohol in the proper amount every day.
D.Having a cigarette before going to bed every day.

We can learn from the passage that

A.Susan Jebb did not take part in the study.
B.the study observed people as well as tested specific changes.
C.there's no need for people under 45 to adopt these good habits.
D.only those from first class can benefit from these healthy behaviors.

What can be inferred from the passage?

A.All the people are well aware of the harm of their bad habits.
B.People aged 45 to 70 have bad habits in the United Kingdom.
C.Governments should take measures to help people change their bad habits.
D.People have adopted the four healthy habits after knowing they're good.

When I lived in Spain, some Spanish friends of mine decided to visit England by car. Before they left, they asked me for advice about how to find accommodation (住所). I suggested that they should stay at ‘bed and breakfast’ houses, because this kind of accommodation gives a foreign visitor a good chance to speak English with the family. My friends listened to my advice, but they came back with some funny stories.
“We didn’t stay at bed and breakfast houses,” they said, “because we found that most families were away on holiday.”
I thought this was strange. Finally I understood what had happened. My friends spoke little English, and they thought ‘VACANCIES’ meant ‘holidays’, because the Spanish word for ‘holidays” is ‘vacaciones’. So they did not go to house where the sign outside said ‘VACANCLES’, which in English means there are free rooms. Then my friends went to house where the sign said ‘NO VACANCLES’, because they thought this meant the people who owned the house were not away on holiday. But they found that these houses were all full. As a result, they stayed at hotels!
We laughed about this and about mistakes my friends made in reading other signs. In Spanish, the word ‘DIVERSION’ means fun. In English, it means that workmen are repairing the road, and that you must take a different road. When my friends saw the word ‘DIVERSION’ on a road sign, they thought they were going to have fun. Instead, the road ended in a large hold.
English people have problems too when they learn foreign languages. Once in Paris. when someone offered me some more. coffee, I said ‘Thank you’ in French. I meant that I would like some more, However , to my surprise the coffee pot was taken away! Later I found out that ‘Thank you’ in French means ‘No, thank you.’
My Spanish friends wanted advice about ______.

A.learning English B.finding places to stay in England
C.driving their car on English roads D.going to England by car

I suggested that they stay at bed and breakfast houses because ______.

A.they would be able to practise their English

D.there would be no problem about finding accommodation there

“NO VACANCIES” in English means ______.

A.no free rooms B.free rooms
C.not away on holiday D.holidays

If you see a road sign that says ‘Diversion’, you will ______.

A.fall into a hole
B.have a lot of fun and enjoy yourself
C.find that the road is blocked by crowds of people
D.have to take a different road

When someone offered me more coffee and I said ‘Thank you’ in French,
I ______.

It was early morning. Peter Corbett helped Mark Wellman out of his wheelchair and onto the ground. They stood before El Capitan, a huge mass of rock almost three-quarters of a mile high in California’s beautiful Yosemite Valley. It had been Mark’s dream to climb El Capitan for as long as he could remember. But how could a person without the use of his legs hope to try to climb it?
Mark knew he couldn’t finish the climb alone, but his friend Peter, an expert rock climber, would be there to lend a helping hand. He and Mark thought that it would take seven days to reach the top.
Peter climbed about 100 feet up and hammered a piton(岩钉) into the rock. Fastening one end of a 165-foot rope to the piton, he let one end of the rope fall down. Mark caught the rope and fastened it to his belt with a special instrument. This instrument would allow Mark to move upward, but would prevent him from falling even as much as a single inch. He next reached above his head and fastened a T-shaped bar to the rope, using the same kind of instrument.
Mark took a deep breath, pushed the T-bar up almost as far as his arms could reach, and began the first of the 7, 000 pull-ups needed to reach the top. High above, Peter let out a cheer. “You’re on your way.”
Seven years before, at the age of twenty-one, Mark had fallen while mountain climbing, injuring his backbone. The fall cost him the use of his legs, but he never lost his love of adventure or his joyful spirit.
For the first four days the two men progressed steadily upward without incident. But on the fifth day an unbearably hot wind began to blow, and as time went by, it became stronger and stronger, causing Mark to sway(摇摆) violently on his rope. But Mark kept on determinedly pushing up the T-bar and pulling himself up. In spite of that, he had to admit that he felt a lot better when the wind finally died down and his body touched solid rock again.
It took them one day more than they had expected, but on July 26 at 1:45 in the afternoon, the crowd of people waiting on the top went wild with joy as the two heads appeared. Mark Wellman had shown that if you set your heart and mind on a goal, no wall is too high, no dream impossible.
What had Mark Wellman long desired to do?

A.To finish one of the most difficult rock climbs in the world.
B.To be the first to climb El Capitan.
C.To climb the highest mountain in California.
D.To help his friend Peter climb El Capitan.

How did Mark climb the mountain?

A.He fastened the rope to his wheelchair.
B.He hammered in pitons so that he had something to hold on to.
C.He held on to the T-bar and Peter pulled him up.
D.He pulled himself up using a T-bar and special equipment.

How did Mark lose the use of his legs?

A.He lost his footing and fell from the side of a mountain.
B.He fell during his first attempt on El Capitan.
C.His legs were broken by falling rocks.
D.While working out in the gym, he injured his backbone.

What was the worst problem Mark had during the climb?

A.He struck against the rock and hurt his arms.
B.A strong wind blew him away from the rock.
C.He kept falling several inches.
D.While swaying in space, he became terrified.

How did Mark react to difficulties during the climb?

A.He admitted that he was frightened.
B.He often worried about his friend’s condition.
C.He was able to remain clam and determined.
D.He was joking to cheer himself up.

The fiddler crab (蟹) is a living clock. It shows the time of day by the colour of its skin, which is dark by day and pale by night. The crab’s changing colour follows a regular twenty—four hour plan that exactly matches the daily rhythm of the sun.
Does the crab actually keep time, or does its skin simply answer to the sun’s rays, changing colour according to the amount of light strikes it? To find out, biologists kept crabs in a dark room for two months. Even without daylight, the crab’s skin colour continued to change exactly on time.
This characteristic probably developed gradually in answer to the daily rising and setting of the sun, to help protect the crab from sunlight and enemies. After millions of years it has become completely regulated (受控制) inside the living body of the crab.
The biologists noticed that once each day the colour of the fiddler crab is especially dark, and that each day this happens fifty minutes later than on the day before. From this they discovered that each crab follows not only the rhythm of the sun but also that of the tides (潮水). The crab’s period of greatest darkening is exactly the time of low tide on the beach where it was caught!
The fiddler crab is like a clock because it changes colour ______.
A in a regular 24—hour rhythm B. in answer to the sun’s rays
C. at low tideD. every fifty minutes
The crab’s changing colour ______.

A.tells the crab what time it is B.protects the crab from the sunlight and enemies
C.keeps the crab warm D.is of no real use

When the fiddler crabs were kept in the dark , they ______.

A.did not change colour B.changed colour more quickly
C.changed colour more slowly D.changed colour on the same timetable

The crab’s colour—changing ability was probably developed ______.

A.in the process of evolution (进化) B.over millions of years
C.by the work of biologists D.both A and B

The best title for this selection would be ______.

A.The Sun and the Tides B.Discoveries in Biology
C.A scientific Study D.A Living Clock
