Scientists believe that conditions on Mars around 3.8 billion years ago were very similar to those of the early earth, when primitive organisms were spreading through our oceans. At that time, Mars would have been much warmer and wetter than it is today, with an atmosphere composed mainly of carbon dioxide, just like that of the earth at the time. Under these conditions, it is highly probable that life may have arisen on Mars as well.
But, even if life did not arise naturally on Mars, it does not mean that it could not have existed there. According to Professor Paul Davies of the University of Adelaide, Australia, life forms could have been transferred between the earth and Mars in wreckage (broke pieces) created by the impact of comet(彗星) and small planets on the surface of the two planets.
Even today, about 500 tons of material from Mars lands on earth every year. It is mainly in the form of the dust but occasionally a larger chunk(厚片，大块) strikes the earth. In 1911, a piece of Martian rock crashed in Egypt, killing a dog. According to Professor Davies, it is in these chunks of rock, which were much larger and more frequent in the past that life forms could have been transported from planet to planet.
“But how could these life forms have survived their journey through space?” says Paul Davies, “The difficulty in believing this theory is that a bacterium on its own in space has to struggle itself not only against cold but also against deadly cosmic (宇宙的) radiation. But wrapped in a rock the situation is different. A rock ten meters across would shield life inside it from a lot of radiation and the temperature might only be minus 10 or 20 degrees, the sort of thing we have on earth.”

Most people feel lonely sometimes, but it usually only lasts between a few minutes and a few hours. This kind of loneliness is not serious. In fact, it is quite normal. For some people, though, loneliness can last for years. Now researchers say there are three different types of loneliness.
The first kind of loneliness is temporary. This is the most common type. It usually disappears quickly and does not require any special attention. The second kind, situation—for example, family problem, the death of a loved one, or moving to a new place. Although this kind of loneliness can cause physical problems, such as headaches and sleeplessness, it usually does not last for more than a year.
The third kind of loneliness is the most severe. Unlike the second type, chronic（the opposite of “temporary”）usually lasts more than two years and has no specific cause. People who experience habitual loneliness have problems socializing and becoming close to others. Unfortunately, many chronically lonely people think there is little or nothing they can do to improve their condition.
Psychologists agree that one important factor in loneliness is a person’s social contacts, for example, friends, family members, co-workers, etc. We depend on various people for different reasons. For instance, our families give us emotional support, our parents and teachers give us guidance, and our friends share similar interests and activities. However, psychologists have found that, though lonely people may have many social contacts, they sometimes feel they should have more. They question their popularity.
Psychologists are trying to find ways to help habitually lonely people for two reasons: they are unhappy and unable to socialize and there is a connection between chronic loneliness and serious illness as heart disease, while temporary and situational loneliness can be a sad, and sometimes dangerous condition.

Whenever we meet with difficulty or failure, teachers, parents or others often say to us or perhaps we say to ourselves, “Never give up.” These can be encouraging words and words of determination. A person who believes in himself will keep trying to reach his goal no matter how many times he fails. In my opinion , the quality of determination to succeed is an important one to have. Therefore, I believe that we should never give up.

One reason is that if we give up too easily, we will rarely achieve anything. It is not unusual for us to fail in our first attempt at something new, so we should not feel disappointed and should try again. Besides, if we always give up when we fail , we will not be able to develop new skills and grow.

Another reason we should never give up is that we can learn from our mistakes so that we can not make the same ones. If we do not try again, the lesson we have learned is wasted.

Finally, we should never give up because as we work to reach our goals, we develop confidence, and this confidence can help us succeed in other areas of our lives. If we never challenge ourselves, we will begin to doubt our abilities.

In short, it is important that we do not give up when working for our goals. Whether we succeed in the end or not , we will learn something , and what we learn will help us to become better and more confident. Furthermore, if we give up , we have no chance of attaining our goals any more , but if we keep making great efforts, there is always a chance that we will succeed one day.

New research says 35 percent of child deaths worldwide are caused by hunger. The research comes from poor to middle-income countries in Africa, Asia and Latin America.

Robert Black from the Bloomberg School of Public Health at Johns Hopkins University in Maryland is the lead writer of the research. He says more than 3.5 million mothers and children under five die in poor countries each year because of hunger.

He says about two million children die from underdevelopment, either before or after birth. Millions of others who survive face a lifetime of disabilities or early death and the effects are not just physical. Poor mental development also results from hunger as children grow. Then the

cycle of poverty and hunger often continues for their children.

Doctor Black says hungry children can have conditions like high blood pressure and heart disease as a result of hunger. He says the studies show that food programs need to place the greatest importance on the first two years of life. Hungry children can suffer their whole life damage from age two.

It is high time their diets were improved. Diets should include foods rich in vitamin A and other vitamins and minerals. The researchers say early help such as this could reduce child deaths by 25%.

This research has also faced some criticism. A medical aid group says the researchers underestimate(低估) the number of child deaths due to hunger. The researchers say there are findings that support this treatment but more studies are needed to compare it to hospital care.

At the age of twelve years, the human body is at its most vigorous. It has yet to reach its full size and strength, and its owner his or her full intelligence; but at this age the likelihood of death is least. Earlier we were infants and young children, and consequently more vulnerable; later, we shall undergo a progressive loss of our vigour and resistance which, though not felt at first, will finally become so sudden and quick that we can live no longer, however well we look after ourselves, and however well society, and our doctors, look after us. This decline in vigour with the passing of time is called ageing. It is one of the most unpleasant discoveries which we all make that we must decline in this way, that if we escape wars, accidents and diseases we shall eventually die of old age, and that this happens at a rate which differs little from person to person, so that there are heavy odds in favour of our dying between the ages of sixty-five and eighty. Some of us will die sooner, a few will live longer-- on into a ninth or tenth decade. But the chances are against it, and there is a virtual limit on how long we can hope to remain alive, however lucky and strong we are.

Normal people tend to forget this process unless and until they are reminded of it. We are so familiar with the fact that man ages, that people have for years assumed that the process of losing vigour with time, of becoming more likely to die the older we get, was something self-evident, like the cooling of a hot kettle or the wearing-out of a pair of shoes. They have also assumed that all animals, and probably other organisms such as trees, or even the universe itself, must in the nature of things 'wear out'. Most animals we commonly observe do in fact age as we do if given the chance to live long enough; and mechanical systems like a wound watch or the sun, do in fact run out of energy in accordance with the second law of thermodynamics (whether the whole universe does so is a matter about which there may be disagreement or uncertainty at present). But these are not similar to what happens when man ages. A run-down watch is still a watch and can be rewound. An old watch, by contrast, becomes so worn and unreliable that it eventually is not worth mending. But a watch could never repair itself, it does not consist of living parts, only of metal, which wears away by friction. We could, at one time, repair ourselves well enough, at least, to overcome all but the most instantly fatal illnesses and accidents. Between twelve and eighty years we gradually lose this power; an illness which at twelve would knock us over, at eighty can knock us out, and into our grave. If we could stay as vigorous as we are at twelve, it would take about 700 years for half of us to die, and another 700 for the survivors to be reduced by half again.

The ____71____ of ageing	Infants and children under 12 are more easily ____72___ physically or emotionally. At 12, we are ____73____ active and full of energy. Later, we will ___74___ our energy or enthusiasm continuously. Finally we can’t live any longer no matter how ___75___ we are cared for.
The characteristics of ageing	Not noticeable at first Not avoidable in the end Not the ____76___ speed for everyone
People’s misunderstanding of ageing	Just taking the ageing with time ____77___ for granted. Simply thinking all living things or other systems also ___78___ the same way as we humans do.
Truth about ageing	We humans can ___79___ ourselves well enough to live a longer life, ___80___ the other living things or systems can’t.

People say teenagers are no good. They make too much noise in shopping malls; they drive recklessly up and down America’s main streets; they carry chips on their shoulders as big as the Sears Tower. And at least some of the time those things are true. But we shouldn’t forget that there are hard moments in the life of a teenager too.

　　I watched such a moment not long ago at a woman’s funeral. I didn’t expect the event to affect me. Through much of the ceremony, in fact, I remained unmoved.

　　Then her teenage grandson stepped forward. With his very first deep breath, every heart in that church was achingly reminded of something we had all forgotten. Softly he began: “I want to share a few values that Nana taught me. She never failed to see light in any situation. When our family dog would literally attract her, what would Nana say? ‘Oh, what beautiful markings that dog has.’ That was Nana.

　　“She was a strong woman who often lived in the shadow of my grandpa, who was a successful businessman in this city. But she was the one behind the scenes who provided the strength and support for Grandpa’s career,” he said, with a voice now trembling. “That was Nana’s way.”

　　Through a muffled sob, he continued. “Whenever she did anything worth recognition, you’d have to hear about it from a different source, because she was never one to brag.”

　　Finally, in a voice breaking free of sorrow, he looked up and said, “Nana taught me courage. She put up an incredible fight to the end, when she died peacefully, which is how she lived her life. That was Nana’s way, and I hope I can carry on in the same manner.”

　　There are no hearts as sensitive as those of teenagers, because everything is happening to them for the first time. The trouble with teenagers is that they haven’t learned to be controlled.

　　When that boy rose to speak about the woman who surely had been his truest ally and dearest friend, his honest voice dragged each of us out into the open where we could no longer hide in the calm ritual. He exposed us to the truth about this very real woman who believed in a boy who probably tried the patience of many adults. He reminded us that his grandmother was more than another dot on the chart of life and death.

　　All over again we felt those powerful losses crisscrossing our own hearts, and we knew that when you say good-bye to a beloved grandparent, you say good-bye to something happy, something young in yourself. And that something never really returns, and the pain never really goes away.
