Have you heard of the following places on Earth that look completely alien? Waiotapu, New Zealand Steam and gases rising through the pool create bubbles of mud, at the site of what was once a volcano. While Waiotapu is a popular tourist spot, visitors are warned to stay on walkways built by the government for fear that they fall through thin crust surfaces and risk being burned by hot geothermal gases or fluids. Rio Tinto, Spain Rio Tinto is a river in southwestern Spain that originates in the Sierra Morena mountains of Andalusia. It flows generally south - southwest, reaching the Gulf of Cadiz at Huelva. As a possible result of the mining, Rio Tinto is notable for being very acidic (pH 2) and its deep red color1 is due to iron dissolved in the water. The Pinnacles, Australia This stretch of desert landscape in Australia's Nambung National Park boasts thousands of weathered rock projections that rise out of yellow sand hills -- some topped by round roofs, while others form sharp-edged columns. The spires , some of which reach 11 feet in height, are limestone formations sculpted by wind, vegetation, rain, sun and time over millions of years. Kilauea Volcano, Hawaii The closest thing on Earth to a Venusian environment may be the smooth, black basalt formations on Hawaii's Big Island. One of the best examples of a Venus-like volcano is Kilauea Volcano, the youngest and southernmost volcano on the island, and one of the world's most active. Since 1952, there have been more than 34 eruptions at Kilauea, which in Hawaiian tradition is the home of Pele, the volcano goddess. Where should you go if you want to watch an active volcano? A) New Zealand. B) Spain. C) Australia. D) Hawaii.

One day, around Christmas time, fishermen off the west coast of Peru started on their traditional fishing trip. Much to their surprise, there were no fish! They knew immediately what had happened. Tales from years gone by had told them this was the result of El Nino which sometimes stop fishing for many months! El Nino is a warm _ that comes and goes along the west coast of South America. It got its name from fishermen in Peru more than a century ago. Every few years, they noticed a sudden warming in the normally cool Pacific water where they fished. Because this warming often came about around Christmas, they called it El Nino, which is Spanish for the "Christ Child". Generally, El Nino occurs every three to seven years and lasts only a few weeks to a month or more. El Nino warms the water it flows through. Because the fish and sea birds need cold water to live, many of them die when El Nino comes through. El Nino also causes both floods and droughts. It is believed that El Nino may have caused the 1993 Mississippi and 1995 California floods. And at the same time, it may have caused droughts in South America, Africa and Australia. El Nino has occurred thirteen times within the last fifty years, bringing natural disasters to many countries such as Indonesia and Peru. However, El Nino does not often trouble China. During this period China was badly hit by El Nino only once. In 1998, North China had a terrible drought, while South China was troubled by floods. According to the passage, which of the following is TRUE about El Nino? A) It happens in November and December. B) It was named by some Spanish fishermen. C) It only happens in South America. D) It lasts a few weeks or more.

Ques: It is pretty much a one-way street. While it may be common for university researchers to try their luck in the commercial world, there is very little traffic in the opposite direction. Pay has always been the biggest deterrent, as people with families often feel they cannot afford the drop in salary when moving to a university job. For some industrial scientists, however, the attractions of academia outweigh any financial considerations. Helen Lee took a 70% cut in salary when she moved from a senior post in Abbott Laboratories to a medical department at the University of Cambridge. Her main reason for returning to academia mid-career was to take advantage of the greater freedom to choose research questions. Some areas of inquiry have few prospects of a commercial return, and Lee's is one of them. The impact of a salary cut is probably less severe for a scientist in the early stages of a career. Guy Grant, now a research associate at the Unilever Centre for Molecular Informatics at the University of Cambridge, spent two years working for a pharmaceutical company before returning to university as a post-doctoral researcher. He took a 30% salary cut but felt it worthwhile for the greater intellectual opportunities. Higher up the ladder, where a pay cut is usually more significant, the demand for scientists with a wealth of experience in industry is forcing universities to make the transition to academia more attractive, according to Lee. Industrial scientists tend to receive training that academics do not, such as how to build a multidisciplinary team, manage budgets and negotiate contracts. They are also well placed to bring something extra to the teaching side of an academic role that will help students get a job when they graduate, says Lee, perhaps experience in manufacturing practice or product development. "Only a small number of undergraduates will continue in an academic career. So someone leaving university who already has the skills needed to work in an industrial lab has far more potential in the... What contribution can industrial scientists make when they come to teach in a university? A) Increase its graduates' competitiveness in the job market. B) Develop its students' potential in research. C) Help it to obtain financial support from industry. D) Gear its research towards practical applications.
Ans: A
Question: Common sense would tell us that physically active children may be more likely to become active and healthy adults. In the United States, elementary and middle schools are advised to give students two and a half hours of physical activity a week. That is what the Centers for Disease Control and Prevention and the American Heart Association recommend. They say high schools should provide about four hours of physical activity each week. Yet many schools across the country have reduced their physical education programs. Just this week, a study reported that life _ has fallen or is no longer increasing in some parts of the United States. The situation is worst among poor people in the southern states, and especially women. Public health researchers say it is largely the result of increases in fatness, smoking and high blood pressure. They also blame differences in health services around the country. In 2006, a study found that only four percent of primary schools provided daily physical education all year for all grades. This was true of eight percent of middle schools and two percent of high schools. The study also found that twenty-two percent of all schools did not require students to take any P.E. Charlene Burgeson , a health expert says one problem for P.E. teachers is that schools are under pressure to put more time into academic subjects. Also, parents may agree that children need exercise in school. Yet many parents today still have bad memories of being chosen last for teams because teachers favored the good athletes in class. But experts say P.E. classes have changed. They say the goal has moved away from competition and toward personal performance, as a way to build a lifetime of activity. These days, teachers often lead activities like weight training and yoga. Some parents like the idea of avoiding competitive sports in P.E. class. Yet others surely dislike that idea. In the end, schools may find themselves in a no-win situation. What can be inferred after you read this passage? A) Physical activities are becoming more and more popular in American schools. B) All the schools provided daily physical education all year for all students. C) Parents think children need physical education for their bad memories. D) Students spent less time on physical education for academic pressure.
