Not all think laughter is the best medicine, but it seems to help．So scientists carried on a new study of diabetes （糖尿病） patients who were given a good dose of humor for a year to prove it．
Researchers divide 20 high-risk diabetic patients into two groups．Both groups were given standard diabetes medicine．Group L viewed 30 minutes of humor of their choice, while Group C, the control group, did not．This went on for a year of treatments．
By two months into the study, the patients in the laughter group had lower level of the hormones epinephrine （肾上腺素）, considered to cause stress, which is known to be deadly．After the 12 months, HDL cholesterol rises 26 percent in Group L but only 3 percent in Group           C．In another measure, C-reactive proteins, a maker of heart disease, drop 66 percent in the laughter group but only 26 percent in the control group．
“The best doctors believe that there is a physical good brought about by the positive emotion, happy laughter,” said study leader Lee Berk of Loma Linda University．And other research has found that humor makes us more hopeful．Still, more study is needed, Berk said．The research by Berk found that humor can bring about similar changes in body chemistry, which was proved in the new study．The research result will be presented this month at the meeting in the US．Research at the University of Maryland School of Medicine shows that laughter causes the inner lining of blood vessels to expand, increasing blood flow in a way thought to be healthy．
“Lifestyle choices have an important effect on health and these are choices which we and patients should pay attention to, rather than prevention and treatment,” Berk said in a statement this week．
【小题1】Why did the scientists carry on the new research?

To be able to motivate oneself, or self-motivate, occurs when a person has the willingness to do something and is internally(内在地) motivated to do it.
Sometimes it’s very difficult to get ourselves moving. The natural tendency is to postpone. Life just seems to get in the way! There is a job to go to, groceries to do, television to watch—whoops! I guess we get pretty good at finding excuses to escape getting started on goals like an exercise routine or reading a new book. The fact is that we are creatures of routine and habit. So what can we do to motivate ourselves to accomplish our goals? 
Here are some tips on how to get moving:
l Decide what you want. It’s hard to motivate an aimless mind. Set a goal and decide how you are going to go about it. Then break it down into smaller sections so it’s easier to handle and less overwhelming.（势不可挡）
l Keep track of your progress. Keep a log or journal where you can measure how much you have accomplished. Looking at it can also motivate you to keep pushing ahead.
l Post motivating pictures or slogans within your sight. It is always inspiring to see pictures of people who have accomplished what you’re going for. It makes it attainable and realistic. Likewise, little slogans like “go for it” or “just do it” can give you the little support you need.    
l Sometimes we forget what we set out to do and a little reminder is all we need to be revitalized (激活) and focus on the end result. If you remind yourself to go for the desired promotion, it will re-establish why you are doing what you’re doing.
l Make it a habit. Once you have accomplished your objective, e.g. becoming an early riser, keep it up so that it’s second nature to you and you don’t have to think about it anymore.

A. self-motivation needs repeated self-reminding of one’s goal
B. in modern society people tend to become forgetful
C. when we forget our goal, our life becomes meaningless
D. we can achieve our goal only by focusing on the end result
66. To get moving on your goal, you can do the following EXCEPT ________.
A. keep a diary to clearly judge your distance to your goal
B. make self-improvement your second nature
C. forget your aim and revitalize yourself with slogans
D. support yourself by hanging inspiring pictures in your house

Bissel is a small village of the West Sahara. It lies next to a l.5-square-kilometer oasis（绿洲）, from where three days and nights are generally required to go out of the desert. However, before Ken Levin discovered it in 1926, none of the Bissel villagers had ever walked out of the desert. Reportedly, they were not unwilling to leave this barren land. Many had previously tried but failed, always somehow finding themselves back at the oasis after several days of trying to walk out.

When interviewed by Ken Levin, an expert at the British Royal College of Sciences, the villagers explained that no matter which direction they walked it always brought them back to the village.Why couldn’t the Bissel villagers walk out of the desert? Levin was very puzzled. He had, by himself, managed to walk north from the village and reach the nearest town in three and a half days. He decided to carry out an experiment to solve the mystery. He and a Bissel villager called Argutel, would walk out of the desert together. They prepared enough water for a half-a-month journey and two camels. But this time Ken Levin didn't bring his compass. Levin would follow Argutel.

Ten days later, they had walked for about 500 miles but were still in the desert. On the 11th morning, an oasis came into their view. They were back at Bissel. Levin now understood why the Bissel people couldn’t escape the desert. They had no knowledge of the North Star, which had for centuries provided sailors and other travelers with a point of direction. In the desert, if a person goes forward relying only on their senses, they will not be able to travel in a straight line. Rather they will travel in a very large circle and eventually track back to where they began. Levin explained to Argutel the function of the North Star and said, “As long as you rest in the daytime and walk towards the brightest star at night, you would be able to walk out of the desert.” Argutel did as he was told. Three days later, he came to the edge of the desert.

Now in the West Sahara, Bissel has become a bright pearl, where tens of thousands of tourists come every year. Argutel’s bronze statue stands in the center of the town. On its base are the words: __________________________.

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

A. Ken Levin didn’t walk south because it would take more days

B. the use of a compass was necessary to walk out of the desert

C. tourism in Bissel has been greatly developed and improved

D. Argutel became the leader of Bissel after his return

Last week, I bought an alarm system for about $ 450. It consisted of a control unit with three small units. I put the control unit in the sitting-room and fastened the other units by the front door, back door and living-room windows. The instructions told us to choose three numbers, so we chose 4, 9 and 1, the last three numbers of our telephone number.
Now I must explain how the alarm works:
l There is a power siren(警报器) in the control unit. It makes a very loud noise.
2 Each of the small units sends out beams or rays in different directions. If anything moves, it breaks a beam. This sends a signal to the control unit. The siren makes a noise which you can hear 50 meters away.
3. When we go to bed, I press the three buttons numbered 4, 9 and 1. Then we have 30 seconds to get out of the room before the alarm starts to work.
That night I slept soundly because I was sure that no burglar(夜贼) could get into our house. However, at about 2:10 a. m., I woke up and heard the siren. “There must be a burglar in the house,” Mary said. “What shall we do?”“I’ll go and see who’s there,” I said. “Stay here. Don’t make a noise.”I went downstairs quietly. When I reached the living-room, I switched on my torch and looked round the room. Then I turned the light on. I switched the siren off and searched the rooms downstairs. There was nothing wrong except that the back door was unlocked. I locked it, reset the alarm and went back to bed. About an hour later, the alarm started again. I jumped out of bed, fell over a chair in the dark and bumped into the bedroom door. Mary woke up and started hitting me with a torch. “Hey! Wait a minute!” I whispered. “It’s only me. I’m going downstairs to see what’s wrong.”I went down into the living-room and listened for a moment. The only sound I could hear was the siren. I turned on the light and then switched the siren off. As I did so, I glanced across at the curtains in front of the windows. I saw a house lizard (a kind of small animal) disappear behind the curtains.“Oh!” I said to myself. “That’s our burglar. ”When the lizard moved, it started the siren. I guessed that the alarm had been made in Europe, where there are no house lizards. Well. I won’t finish this story but if you want an alarm system free of charge, let me know. I’ll send you ours. We bought a dog this morning. It knows the difference between a lizard and a burglar.

There is a saying in France that states, "The government could fall, the Louvre （卢浮宫）could be broken into or creatures from other planets could land on earth, but if any of these things happened during the Tour de France, no one would notice．" The Tour de France is the most famous cycling race in the world．It begins in July and runs for three weeks．Cyclists who race in the Tour de France ride in six legs or stages of the race, and they have between one to four days of rest between each leg of the race．The rider who completes all six legs of the race in the shortest overall time wins．

    The Tour de France began as a publicity stunt（惊人的表演） for the French sports newspaper, L’Auto．Hcnri Desgranges, who worked for L’Auto,  came up with the idea for "the greatest bike race in the world, "and on July 1,1903, the first Tour de France began．Sixty cyclists began that first leg of the race which started in front of the Alarm Clock Cafe just outside of Paris．This first leg took them 467 kilometers to Lyon．The first Tour de France received an astonishing 2,000 francs．Maurice Garin, the most popular cyclist in France at that time, won the first Tour de France．It took him 94 hours and 33 minutes to ride all 2,428 kilometers of the race．This time was three hours faster than the second -place rider．Over the weeks during which the race was run, the idea of the Tour de France slowly caught the imagination of the people of France．The race has been run every year since that time, except during the years of World War I and World War Ⅱ．

    The Tour de France has developed several special honors for which racers compete．Above all, the highest honor is the " yellow jersey"．Mr．Desgranges introduced the yellow jersey in 1919 to show the leading racer each rider's total time in order to find the racer with the lowest time．That racer wears the yellow jersey during the day's race．Other honors include the "green jersey " which is given to the rider who sprints the best by riding the fastest over short distances, and the "polka dot jersey" for the best rider in the mountains along the route．
