The $11 billion self-help industry is built on the idea that you should turn negative thoughts like “I never do anything right” into positive ones like “I can succeed.” But was positive thinking advocate Norman Vincent Peale right? Is there power in positive thinking?

　　Researchers in Canada just published a study in the journal Psychological Science that says trying to get people to think more positively can actually have the opposite effect: it can simply highlight how unhappy they are.

　　The study’s authors, Joanne Wood and John Lee of the University of Waterloo and Elaine Perunovic of the University of New Brunswick, begin by citing older research showing that when people get feedback which they believe is very positive, they actually feel worse, not better. If you tell your stupid friend that he has the potential of an Einstein, you’re just underlining his faults. In one 1990s experiment, a team including psychologist Joel Cooper of Princeton asked participants to write essays opposing funding for the disabled. When the essayists were later praised for their sympathy, they felt even worse about what they had written.

　　In this experiment, Wood, Lee and Perunovic measured 68 students’ self-esteem. The participants were then asked to write down their thoughts and feelings for four minutes. Every 15 seconds, one group of students heard a bell. When it rang, they were supposed to tell themselves, “I am lovable.”

　　Those with low self-esteem didn’t feel better after the forced self-affirmation. In fact, their moods turned significantly darker than those of members of the control group, who weren’t urged to think positive thoughts.

　　The paper provides support for newer forms of psychotherapy (心理治疗) that urge people to accept their negative thoughts and feelings rather than fight them. In the fighting, we not only often fail but can make things worse. Meditation techniques, in contrast, can teach people to put their shortcomings into a larger, more realistic perspective. Call it the power of negative thinking.

1.What do we learn from the first paragraph about the self-help industry?

4.What do we learn from the last paragraph?

Agence Rrance-Presse--- French doctors this week carried out the world’s first operation on a human in zero gravity, using a specially adapted aircraft to create conditions in space.

During a three-hour flight from Bordeaux in southwest France, the team of surgeons and anesthetists (麻醉师) successfully removed a benign tumor (良性瘤) from the forearm of a 46-year-old volunteer. The experiment was part of a program backed by the European Space Agency to develop techniques for performing robotic surgery aboard the International Space Station or at a future Moon base.

“Now we know that a human being can be operated on in space without too many difficulties,” says the team leader Dr. Dominique Martin.

Under normal ground conditions, the operation would be performed under a local anesthetic. Without gravity, the surgeon’s work is harder and the patient’s body reacts differently. Blood doesn’t pump in the same way.

The custom-designed Airbus 300 aircraft performed a series of parabolic swoops (抛物线飞行), each creating between 20 seconds of weightlessness. The process was repeated 32 times.

Fixed inside a custom-made operating block, three surgeons and two anesthetists worked during these periods, with their instruments held in place with magnets around the patient’s bed. The next part of the program is to carry out a remote-controlled operation using a robot controlled from the ground by satellite. This experiment should take place within a year, Martin says.

Anesthetist Dr. Laurent de Coninek says that zero-gravity surgery offers huge promise for space exploration, although it would at first be limited to treating simple injuries. Today more than 400 people have already traveled into space. The chances of injuries occurring during missions will become even greater and to bring a wounded person back to the earth for treatment is both risky for them and expensive.

67. What would be the best title for the test?

A. A Special Operation for Doctors            B. First Operation on the Moon

C. World’s First Operation in Zero Gravity      D. An Important Experiment for Doctors

68. What’s the purpose of the operation?

A. To have an experiment on space operation.    B. To cure the patient.

C. To do it at the request of the patient.               D. To reduce the danger of operation on earth.

69. It is difficult for doctors to do operations in space because________________.

A. the patient’s illness will be more serious           B. the patient has no feeling about pain

C. the patient’s body reacts differently               D. the patient’s flood will stop flowing

70. The last paragraph mainly wants to tell readers________________.

A. there are many people injured in space           B. it is necessary to do the experiment

C. it is risky to travel in space                             D. there is no need to bring patients in space to the earth

From babies to body builders, we all have muscles. They grow, they bulge(鼓起), they stretch they stretch and sometimes they even painfully pull. But for all the work they do for us, we are still unable to crown one as "the strongest muscle."

Instead, a few muscles could claim the title, depending on how strength is measured.

If the title goes to the muscle that can exert(产生) the most force, the victor would be the soleus（小腿肚肌）, according to Gray's Anatomy（解剖学）. Without this muscle, we wouldn't be able to stand, walk, run or shake our bodies on the dance floor. If the soleus was not continuously pulling, we would always be falling over ourselves (although some of us tend to do that from time to time anyway).

But perhaps the title should go to the muscle that exerts the most pressure. Pressure is different from force — pressure takes into account the area over which a force is exerted. The muscle that takes the prize for delivering the greatest amount of pressure is the masseter, or the jaw muscle, according to the book "Clinical Oral Science" (Reed Educational and Professional Publishing, 1998).

In 1986, Richard Hofmann of Lake City, Fla., achieved a bite strength of 975 pounds (442 kilograms) for two seconds, setting a Guinness Record. Talk about jaw dropping! The jaw is able to clench（咬紧） and chew because of the masseter muscle.

Others may argue the muscles used in childbirth are the most powerful.

When it comes to versatility, perhaps the tongue is the strongest muscle. Its combination of elasticity（伸缩性） and forcefulness gives us the ability to speak, eat and kiss – all things very desirable on a first date. However dexterous（灵巧的） it may be though, its power does not match that of muscles such as the soleus.

If slow and steady wins the race, the heart is certainly a contender for the title. When it contracts, the muscle pumps about 2 ounces (59 milliliters) of blood, and is constantly working over a lifetime. Beating about 40 million times a year, a person's heart will beat approximately 2.5 billion times by the time of their 70th birthday.

1.According the passage, the underlined word “contender” in the last paragraph is closet in meaning to “          ”.

2.Which would be t he best title for the passage?

3.According to the passage,       .

4.What would be discussed in the following paragraph?

Can we turn negative thoughts like “I never do anything right” into positive ones like “I can succeed”? Is there power in positive thinking?

4.What do we learn from the last paragraph?

 1.But still there is a danger that grows every year．Airliners get larger．Some airplanes can hold over 300 passengers．And the air itself becomes more and more crowded．If one giant airliner crashed into another in mid-air, 600 lives could be lost．

2.．Air traffic controllers tell the pilot exactly when to turn, when to climb, and when to come down．The air traffic controllers around a busy airport like London-Heathrow may handle 2500 planes a day．Not all of them actually land at the airport．Any plane that flies near the airport comes under the orders of the controllers there．3.

Recently such a disaster almost happened．4.One, with 69 passengers, had come from Toronto, and the other, with 176 passengers, from Chicago, An air traffic controller noticed on his radar screen that the two planes were too close to each other．He ordered one to turn to the right and to climb．But he made a mistake．He ordered the wrong plane to do this．Fifteen seconds later it flew directly in front of the second plane．They avoided each other by the smallest part of a second．The distance between them was less than that of a large swimming pool. 5..

         A． Even a small mistake on their part could cause a disaster．

         B． Two large jets were flying towards the airport．

         C． Nowadays people like traveling more by air than by car．

         D． Today, air travel is far safer than driving a car on a bus motor-way．

         E． This is an example of the danger that grows every year．

         F．  In a word, air travel is more dangerous, we should choose others．

         G． From the moment an airliner takes off to the moment it lands, every movement is watched on radar screen．
