Ques: Read the article and select the best answer. Article: When NASA astronaut Scott Kelly completes his yearlong mission on the International Space Station next year, he'll come back just a little bit younger than his twin, Mark, than he was before. This is because time travels more slowly in space, a phenomenon first described by Albert Einstein's 1915 theory of general relativity. This December, universities and academies around the world are celebrating the 100th anniversary of the theory's publication. Even 60 years after his death, Einstein is still the most important scientist of the modern era. Looking back as far as 2,400 years ago, only Newton, Galileo and Aristotle were his equals. Born in the era of horse-drawn carriages, his ideas started a technological revolution that brought about more change in one century than in the 2,000 years before. In 1905, Einstein published four important scientific papers. These completely changed people's ideas about space, time, light and matter. In one of these papers Einstein. introduced his theory of special relativity. Two groundbreaking parts of the theory were about the relationship between mass and energy and the speed of light. Einstein was able to show that mass and energy were connected through the formula E=MC2. The theory also says that no object can travel faster than the speed of light. About 10 years later came his theory of general relativity, the theory that modern physics is really based on. In Einstein's mathematics, space has three dimensions, and the fourth dimension is time. Space and time are part of one continuum, called space-time. The presence of mass changes space-time, which explains where gravity comes from. Computers, satellites, telecommunication, lasers, television and nuclear power, many of the biggest developments in the modern world, can be linked to Einstein's work. "We are a different people than we were a century ago," said astrophysicist Michael Shara of the American Museum of Natural. History, "completely different, because of Einstein." However, there's more to him beyond the image... Question: From the article, it can be concluded that _ . Options: A: the theory of general relativity is mainly about space and time B: the theory of general relativity proves that the speed of light is the fastest of all speeds C: the theory of general relativity is about math and has nothing to do with physics D: the most important parts of the theory of special relativity are about space and energy
Ans: A

Ques: Read the article and select the best answer. Article: A young man once went to town and bought himself a pair of trousers. When he got home, he went to his room and put them on. He found that they were about two inches too long. He went into the kitchen, and his mother and two sisters were doing some washing there. He said to them, "The new trousers are too long. They need cutting by two inches. Would one of you mind doing this for me?" His mother and sisters were busy and none of them said anything. But as soon as his mother had finished washing up, she went to her son's room silently and cut the trousers by two inches. She came back without saying anything to her daughters. After supper, the elder sister remembered her brother's trousers. She went to his room and cut the trousers by two inches without saying anything to anyone. The younger sister went to the cinema. But when she came back, she also remembered her brother's trousers. So she went to his room and cut them by two inches, too. Question: If the trousers were 197 inches at first, how long were they at last? Options: A: 191 inches B: 193 inches C: 195 inches D: 199 inches.
Ans: A

Ques: Read the article and select the best answer. Article: Students who want to study in the United States may find that their chances for financial aid are limited. They often have to pay for their education with their own savings or their family's money. A recent report from the Institute of International Education in New York looked at 2008-2009 school year. Colleges and universities in the United States had more than half a million foreign students. 63% of them paid for school mostly by themselves or with family help. 26% percent were supported by the school they attended. There are other sources of financial aid for international students. These include a student's home government or university, or the United States government. Private sponsors, international organizations and employers may also provide support. Yet during the last school year, not many students were able to depend on any of these other sources. Current employers provided the most help. Still, they represented the main support for just four percent of international students. Those at the graduate level, however, are more likely than undergraduates to receive financial aid in the United States. More than 80% percent of foreign undergraduates depended mostly on personal and family money to pay for school last year. The same was true of less than half of graduate students. Most of the others received financial aid from their college or university in the United States. A list of American schools that offer financial aid to foreign students can be found at a useful Web site. The address is edupass.org. This site also provides information about scholarship programs. But it warns foreign students not to pay if there is any charge for scholarship application forms. You could be cheated out of your money. Question: Which of the following statements is true according to the text? Options: A: Foreign students have no chance to get money from American schools. B: Most foreign graduate students depend on their own savings. C: Edupass.org offers financial aid and scholarship information. D: Usually the present employers provide the most financial help.
Ans: D

Ques: Read the article and select the best answer. Article: If you have a watch, don't go to a watchmaker's unless something is wrong with the machinery. Once I had a beautiful watch. And it had kept perfect time. But one night it happened that I forgot to _ it _ . Next morning I went to a watchmaker as I wanted my perfect watch to be set by the exact time.

My beautiful watch began to gain. It gained faster and faster day by day. By the end of the second month it had left all the clocks and watches of the town far behind. I could do nothing but take it to another watchmaker to be regulated. I expected him to regulate the watch at once, but he asked me to come in a week's time. When at last I got my watch back from him, it began to slow down. And I failed to be in time for trains, business affairs, and even missed my dinners. Now I went to a third watchmaker.
