When we hear the words "college students", we usually think of a young person between 18 and 22 years old. But in the U.S.A today, a college student often is much older. In fact, educators say in the next few years colleges and universities may have more older part-time students than traditional   full-time younger students. Educators report a big increase in the number of Americans who attend college and university classes in the evening or at night or weekends. Most of them are older than 25 years old and more have full-time or part-time jobs. Many are in their thirties or forties. Why are so many people deciding to spend their time and money in order to continue their education? Most are doing it because they believe more education will help them to get a better job. Some are industrial workers whose factories have closed. They are learning new skills to prepare for other kinds of work. Some of the part-time students are not pleased with the jobs they have. They are studying for new ones. Some have retired   and are looking for new kinds of work. Two of every three of the students older than 35 are women. Many of them are returning to school after years of staying at home to care for children. Are older students good students? Most teachers say yes. They say older students really want to learn. They ask difficult questions and are not pleased with simple answers. They often get high grades. They often get high grades" means   _  . A) they rise to high grades easily B) they often get very good marks C) they are more likely to receive a master's or a doctor's degree upon graduation D) they often win high prize

Experiments aboard the spaceship Columbia have disproved a theory on the human nervous system which won an Austrian professor a Nobel prize 79 years ago. West German astronaut Ulf Merbold disproved the theory during tests aboard the spaceship yesterday. His discovery is connected with the workings of the inner ear, the body's balance mechanism . In l914 Professor Robert Barany won the Nobel prize for Physiology  and Medicine when he announced that temperature differences affected the inner ear and caused the eyes to blink . His theory was accepted by scientists. But Merbold carried out tests to find if the theory was correct and shocked himself and space officials when he proved it wrong. According to Barany's theory the eyes would blink when cold air was blown into one ear and hot air blown into the other. But if this theory was correct such a movement would be impossible in zero gravity . Both Merbold's eyes continually blinked when the test was carried out. Tests were carried out in outer space in order to   _  . A) find what causes the eyes to blink B) shock the world C) win the prize D) prove the theory

Farming is moving indoors, where the sun never shines, where rainfall is irrelevant   and where the climate is always right. The perfect crop field could be inside a windowless building with controlled light, temperature,humidity,air quality and nutrition. It could be in a New York high- rise or a complex   in the Saudi desert. It may be an answer to the world's food problems. The world already is having trouble feeding itself. Half the people on Earth live in cities, and nearly half of those - about 3 billion - are hungry or ill-fed. Food prices, currently increasing, are badly affected by dryness, floods and the cost of energy required to plant, harvest and transport it. And prices will only get more unstable. Climate change makes long-term crop planning uncertain. Farmers in many parts of the world already are using water available to the last drop. And the world is getting more crowded: by mid-century, the global population will grow from 6.8 billion to 9 billion. To feed so many people may require expanding farmland at the expense of forests and wilderness, or finding ways to greatly increase crop output. Gertjan Meeuws and three other Dutch bioengineers grow vegetables and house plants in closed and regulated environments. In their research station, water flows into the pans when needed, and the temperature is kept constant. Lights go on and off, creating "day" and "night", but according to the rhythm of the plant. Meeuws says a building of 100 square meters and layers of plants could provide a daily diet of 200 grams of fresh fruit and vegetables for the entire population of Ken Bosch, about 140,000 people. Their idea isn't to grow foods that require much space, like corn or potatoes. Sunlight is not only unnecessary but can be harmful. Plants need only specific wavelengths of light to grow. Their growth rate is three times faster than under greenhouse conditions. They use about 90 percent less water than outdoor agriculture. And city farming means producing food near the consumer, so there's on need... What is the purpose of the text ? A) To compare traditional and indoor farming. B) To discuss the influence of climate change. C) To explain the world's food problem. D) To introduce a new model of farming.
