Question: 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

Answer: A

Question: Article: Every day Yang Hongwei takes the bus home from work, staring silently at the European-style villas , luxury cars and twinkling lights from the shopping center that he sees through the window. Yang works for a software company in Zhongguancun. He dreams of such a life, away from poverty, and that hope has kept him in Beijing for three years since he graduated from university. Soon Yang squeezes his way off the bus to the reality of his life: his home--a 10-square-metre room that costs 550 yuan(81 US dollars) or about one-fifth of his salary in rent every month. It's very cold inside the house as it has no central heating system. He has to stand the long and cold winter. Determined to achieve his dream, Yang says he has changed jobs "numerous" times in the past three years and is considering quitting his present job. Yang's frustration over his life as a migrant is shared by many other graduates that have moved into big cities. Together they have come to be called the "ant tribe", a term created by Chinese sociologists to describe the struggles of young migrants, who, armed with their diplomas, flood to big cities in hopes of a better life only to put up with low-paying jobs and poor living conditions. They share every similarity with ants. They live in colonies in crowded areas. They're intelligent and hardworking, yet unknown and underpaid. The term, sociologists have said, also reflects their helplessness in a world governed by the law of the concrete jungle--only the strongest survive. A survey in Ant TribeII found nearly 30 percent of the "ants" are graduates of famous key universities--almost three times the percentage of 2009. Most have degrees in popular majors, such as medicine, engineering, economics and management. In addition, 7.2 percent of the "ants" have at least a master's degree compared to 1.6 percent in 2009. Most said the economic recovery did not really improve their financial situations, and 66 percent said their incomes fell short of their expectations, the survey also found. For two years, Lian Si, a post-doctoral fellow at the Center for Chinese and Global Affairs of Peking University, who has studied the phenomenon, led a team of more than 100 graduate students to follow the groups in university towns like Beijing, Shanghai, Guangzhou, Wuhan and Xi'an. Lian evaluates the total population of the "ant community" in major cities at one million across China, with about 100,000 found in Beijing alone. Lian predicts that an increasingly challenging job market will see the ant tribe growing further in number. Another 6.3 million graduates are expected to join migrant workers and other job hunters in what promises to be a fierce labour competition. The ant tribe's embarrassing living situations have become a serious social issue, and the government should develop "second-and-third-tier cities" to attract more graduates from big cities. However, "ants" expect more study and training opportunities in big cities, which keeps them in positive mindsets despite their situations. As in the case of Yang, he is optimistic about getting a new job soon, having received eight interview offers in a week after sending out his resume. The prospect of landing a higher-paying job keeps him hopeful of moving out of the slum district soon. The sooner the better.
Question: . Yang has worked in Beijing since graduation from university _ .
Options: (A) to live in a beautiful villa of European style (B) to have more opportunities to be promoted (C) to struggle for a better-off life in a big city (D) to enjoy a busy life in a software company

Answer: C

Question: Article: When I was growing up, I had an old neighbor named Doctor Gibbs. He didn't look like any doctor I'd ever known. He never yelled at us for playing in his yard, but was always very kind. When Doctor Gibbs wasn't saving lives, he was planting trees. He had some interesting theories about planting trees. He believed in the principle: "No pain, no gain". He hardly watered his new trees, an attitude which flew in the face of conventional wisdom. Once I asked why and he told me that watering plants spoiled them because it made them grow weaker. He said you had to make things tough for the trees so that only the strongest could survive. He talked about how watering trees made them develop shallow roots and how, if they were not watered, trees would grow deep roots in search of water. So, instead of watering his trees every morning, he'd beat them with a rolled-up newspaper. I asked him why he did that, and he said it was to get the tree's attention. Doctor Gibbs died a couple of years after I left home. Every now and then, I walked by his house and looked at the trees that I'd watched him plant some 25 years ago. They were tall and strong. I planted a couple of trees myself a few years ago. Two years of attending these trees meant they grew up weak. Whenever a cold wind blew, their branches trembled. _ seemed to benefit Doctor Gibb's trees in ways comfort and ease never could. Every night before I go to bed, I check on my two sons. I often pray that their lives will be easy. But lately I've been thinking that it's time to change my prayer. I know my children are going to encounter hardship. There's always a cold wind blowing somewhere. What we need to do is to pray for deep roots, so when the rains fall and the winds blow, we won't be torn apart.
Question: With the trees planted, Doctor Gibbs often _ .
Options: (A) kept watering them every morning (B) talked to them to get their attention (C) paid little attention to them (D) beat them to make them grow deep roots
