Article: The Process of Ageing 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 possibility 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 vague at first, will finally become so steep 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 disease 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 favor 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 physically 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 ran out of energy in accordance with the second law of thermodynamics . But these are not similar or equivalent 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.
Question: What can be learned from this passage is that _ .
Options: (A) people usually are unhappy when they are reminded of ageing (B) children reach their full intelligence at the age of twelve years (C) people are usually more likely to die at the age of twelve years (D) our first twelve years represent the peak of human development

Article: While others look away from trouble, this lady digs in and gets to work. Gretchen Buchenholz, the native New Yorker and mother of six, has worked on behalf of needy and margin1alized families for years in the city. She does everything from buy groceries for homeless families to start schools for children. In 1974 she founded Merricat's Castle, a nursery school that opened its doors to kids of all racial and economic backgrounds, the able-bodied as well as those with disabilities or terminal illnesses. She founded the Association to Benefit Children (ABC), the nonprofit group, some 20 years ago. The story of how she started ABC is pretty amazing. In 1984 she was on her way to a government office to get a day-care permit when, by accident, she entered a room where homeless families were waiting to be placed in a " welfare hotel." She saw three bare cribs with babies lying in them. The children wore no diapers (their parents couldn't afford them), and the room was filthy . After talking to the parents and learning that they and their children were hungry, Gretchen marched out and bought bread, peanut butter, apple juice and diapers. Then she started making phone calls. She dialed the American Red Cross, City Hall and The New York Times. Gretchen has made many people see that we need to recognize these children are not different from our own, and we need to join in and help. Too often, people look away from suffering. But she sets us an example that we should gain strength to do something about it.
Question: She went to the government office _ .
Options: (A) to help those homeless people in the room (B) to apply for a permit for ABC (C) to call on the government to help those homeless children (D) to get permission to look after babies during the day

Article: How to protect children Web fans from unsuitable material on-line while encouraging them to use the Internet has long been discussed in the US. For some parents, the Internet can seem like a jungle, filled with danger for their children. But jungles contain wonders as well as danger. With good guides, some education, and a few precautions( ), the wilds of the Internet can be safely navigated. "Kids have to be on-line. If we tell our kids they can't be allowed to surf the Internet, we're cutting them off from their future," said an expert. Most kids have started to use search engines. Many of them are great for finding tons of interesting Internet sites, and they can also locate places where you might not want your kids to go. There are search engines designed just for kids. A certain software contains only sites that have been selected as safe. The most popular way would be to use what is known as a "content screener". But this can't be wholly reliable( ), and the best thing parents can do is to talk to their kids and let them know what is OK or not OK to see or do on the Internet. Another way is that mum or dad is nearby when the child is surfing the Internet. A few other tips: --Do not put the PC in a child's room but keep it in an area where mum or dad can keep an eye on things. That also makes the Internet more of a family activity. --Ask your child what he or she has been doing and about any friends they make on-line. --Tell your child not to give on-line strangers personal information, especially like address and phone number. And tell your children never to talk to anyone they meet on-line over the phone, send them anything, accept anything from them or agree to meet with them unless you go along.
Question: What is the best way to protect children from improper material?
Options: (A) To talk to the children and persuade them to tell right from wrong. (B) To be nearby when the children are surfing the Internet. (C) To fix a content screener on the computer. (D) To buy some search engines for children.
