Why would things weigh only a quarter as much as they do at the surface of the earth if we took them 4,000 miles out into space？ The reason is this: All objects have a natural attraction for all other objects; this is called gravitational attraction, but this power of attraction between two objects gets weaker as they get farther apart. When the butter was at the surface of the earth, it was 4,000 miles from the center (in other words the radius[半径] of the earth is 4,000 miles). When we took the butter 4,000 miles out, it was 8,000 miles from the center, which is twice the distance.
If you double the distance between two objects, their gravitational attraction decreases (减少) two times two. If you treble (成三倍) the distance, it gets nine times weaker (three times three). If you take it four times as far away, it gets sixteen times weaker (four times four ) and so on.
The best title for this passage is______.
A．The Earth Weight
B．Weight in Space
C．Changing Weight on the Earth
D．Weight on and off the Earth
Human Heart Can Make New Ceils
Solving a longstanding (为时甚久的) mystery, scientists have found that the human heart continues to generate new cardiac (心脏的) cells throughout the life span, although the rate of new cell production slows with age.
The finding, published in the April 3 issue of Science, could open a new path for the treatment of heart diseases such as heart failure and heart attack, experts say.
"We find that the beating cells in the heart, cardiomyocytes (心肌细胞), are renewed," said lead researcher Dr. Jonas Frisen, a professor of stem cell research at the Karolinska Institute in Stockholm, Sweden. "It has previously not been known whether we were limited to the cardiomyocytes we are born with or if they could be renewed," he said.
The process of renewing these cells changes over time, Frisen added. In a 20-year-old, about 1 percent of cardiomyocytes are exchanged each year, but the turnover (更替) rate decreases with age to only 0.45 percent by age 75.
"If we can understand how the generation of new cardiomyocytes is regulated, it may be potentially possible to develop pharmaceuticals (药物) that promote this process to stimulate regeneration after, for example, a heart attack," Frisen said.
That could lead to treatment that helps restore damaged hearts.
"A lot of people suffer from chronic heart failure," noted co-author Dr. Ratan Bhardwaj, also from the Karolinska Institute. "Chronic heart failure arises from heart cells dying," he said.
With this finding, scientists are "opening the door to potential therapies (疗法) to having ourselves heal ourselves," Bhardwaj said. "Maybe one could devise a pharmaceutical agent that would make heart cells make new and more cells to overcome the problem they are facing. "
But barriers remain. According to Bhardwaj, scientists do not yet know how to increase heart cell production to a rate that would replace cells faster than they are dying off, especially in older patients with heart failure. In addition, the number of new cells the heart produces was estimated using healthy hearts -- whether the rate of cell turnover in diseased hearts is the same remains unknown.
The human heart stops producing cardiac cells

The journey two divers(潜水员)made some time ago to the very deepest point on the earth make us realize how much of the world still remains to be studied. The two men went down seven miles to the bottom of the Pacific Ocean inside a small ball to find out if there are any ocean currents(水流)or signs of life.
It was necessary to set out early, so that the ball would come to the surface in daylight, and so be easily found by the mother ship which would be waiting for it. The divers began preparations(准备)early in the morning and soon afterwards, when all was ready, the steel ball disappeared under the surface of the water.
The divers felt as if they were going down steps as they passed through warm and cold layers(层)of water. In time, the temperature dropped to freezing point. They kept in touch with the mother ship by telephone telling how they felt. Then, at a depth(深度)of 3,000 feet, the telephone stopped working and they were quite cut off from the outside world. All went well until some four hours later at 30,000 feet, the men were frightened by a loud, cracking(爆裂)noise: even the smallest hole in the ball would have meant instant death. Luckily, though, it was only one of the outer(外部的)windows that had broken. Soon afterwards, the ball touched the soft ocean floor raising a big cloud of "dust" made up of small dead sea-creatures. Here, powerful lights lit up the dark water and the men were surprised to see fish swimming just above them quite untroubled by the great water pressure(压力). But they did not dare to leave the lights on for long , as the heat from them made the water boil. Quite unexpectedly, the telephone began working again and the faint(微弱的)but clear voices of the divers were heard on the mother ship seven miles away. After a stay of thirty minutes the men began their journey up, arriving three hours later, cold and wet through, but none the worse for their experience.
1. The purpose of the diver's journey to the deepest point on the earth was to find _____.
A. if there are water currents and life in the great depths
B. if people can stand the severe cold in the great depths
C. if there are steps in the great depths
D. if the telephone works well in the great depths
2. The divers set out early in the morning so that _____.
A. they could return to the surface during the day
B. they could see at the bottom of the ocean
C. they could avoid the cold at night
D. they could stay long at the bottom
3. Which of the following statements is true？
A. The ocean water temperature decreases steadily with the depth
B. There are steps on the way to the bottom of the Pacific Ocean
C. There are steps between the water layers of different temperature
D. The water layers of different temperatures made the divers feel as if they were going down steps
4. As the divers went down to the ocean floor, the telephone _____.
A. kept working all the time
B. stopped working at a depth of 3,000 feet and began working again after they reached the bottom
C. stopped working at a depth of 3,000 feet and began working at 30,000 feet
D. stopped working at a depth of 3,000 feet and began working again when they returned to the same depth
5. On the ocean floor, the divers found that _____.
A. there was no life but some small dead sea-creatures
B. fish were swimming as freely as they do near the surface
C. fish were not swimming freely in the dark water
D. fish were not swimming freely under the high water pressure
