[EX Q]: Article: Last August, Joe and Mary Mahoney began looking at colleges for their 17-year-old daughter, Maureen. With a checklist of criteria in hand, the Dallas family looked around the country visiting half a dozen schools. They sought a university that offered the teenager's intended major, one located near a large city, and a campus where their daughter would be safe. "The safety issue is a big one," says Joe Mahoney, who quickly discovered he wasn't alone in his worries. On campus tours other parents voiced similar concerns, and the same question was always asked: what about crime? But when college officials always gave the same answer -----"That's not a problem here,"-----Mahoney began to feel uneasy. "No crime whatever?" comments Mahoney today. "I just don't _ it." Nor should he: in 1999 the U.S. Department of education had reports of nearly 400,000 serious crimes on or around our campuses. "Parents need to understand that times have changed since they went to college," says David Nichols, author ofCreating a Safe Campus. "Campus crime mirrors the rest of the nation." But getting accurate information isn't easy. Colleges must report crime statistics by law, but some hold back for fear of bad publicity , leaving the honest ones looking dangerous. "The truth may not always be serious," warns S. Daniel Carter of Security on Campus, Inc., the nation's leading campus safety watchdog group. To help concerned parents, Carter promised to visit campuses and talk to experts around the country to find out major crime issues and effective solutions.
Question: It is often difficult to get correct information on campus crime because some colleges _ .
Options: (A) receive too many visitors (B) mirror the rest of the nation (C) hide the truth of campus crime (D) have too many watchdog groups

[EX Q]: Article: A scientist working at her lab bench and a six-old baby playing with his food might seem to have little in common.After all,the scientist is engaged in serious research to uncover the very nature of the physical world,and the baby is,well, just playing...right?Perhaps,but some developmental psychologists have argued that this"play"is more like a scientific investigation than one might think. Take a closer look at the baby playing at the table.Each time the bowl of rice is pushed over the table edge,it falls in the ground---and, in the process, it belongs out important evidence about how physical objects interact ; bowls of rice do not flood in mid-sit, but require support to remain stable. It is likely that babies are not born knowing the basic fact of the universe; nor are they ever clearly taught it. Instead, babies may form an understanding of object support through repeated experiments and then build on this knowledge to learn even more about how objects interact. Though their ranges and tools differ, the baby's investigation and the scientist's experiment appear to share the same aim(to learn about the natural world ), overall approach (gathering direct evidence from the world), and logic (are my observations what I expected?). Some psychologists suggest that young children learn about more than just the physical world in this way---that they investigate human psychology and the rules of language using similar means. For example, it may only be through repeated experiments, evidence gathering, and finally overturning a theory, that a baby will come to accept the idea that other people can have different views and desires from what he or she has, for example, unlike the child , Mommy actually doesn't like Dove chocolate. Viewing childhood development as a scientific investigation throws on how children learn ,but it also offers an inspiring look at science and scientists. Why do young children and scientists seem to be so much alike? Psychologists have suggested that science as an effort ---the desire to explore, explain, and understand our world---is simply something that comes from our babyhood. Perhaps evolution provided human babies with curiosity and a natural drive to explain their worlds, and adult scientists simply make use of the same drive that served them as children. The same cognitive systems that make young children feel good about feel good about figuring something out may have been adopted by adult scientists. As some psychologists put it, "It is not that children are little scientists but that scientists are big children."
Question: According to some developmental psychologists,
Options: (A) a baby's play is nothing more than a game. (B) scientific research into babies; games is possible (C) the nature of babies' play has been thoroughly investigated (D) a baby's play is somehow similar to a scientist's experiment

[EX Q]: Article: On a hot August morning, in a classroom overlooking New York's Hudson River, a teacher guides a group of 3-year-olds completely in Chinese. This is just a language summer camp run by the primary school Bilingual Buds, which offers a year-round course in Chinese as well as Spanish for kids as young as 2. A lot of research now shows the regular, high-level use of more than one language may actually improve early brain development. Knowing two or more languages can improve the ability to focus, decide and deal with information better. These important skills are grouped together, known in brain terms as "executive function". The research suggests _ develop ahead of time in bilingual children, and are already evident in kids as young as 3 or 4. Bilingual education, common in many countries, is a growing trend across the United States, with 440 elementary schools offering the study in Spanish, Chinese and French. But Tamar Gollan, a professor at the University of California, has found a vocabulary gap between children who speak only one language and those who grow up with more. On average, the more language spoken, the smaller the vocabulary in each one. Gollan's research suggests that while that gap narrows as children grow, it does not disappear completely. Gollan says, "Vocabulary tests help us find that bilinguals have the disadvantage, where you know the word but you just can't get it out." In fact some of the values of bilingualism can't be measured at all, of course. To speak more than one language is to open the mind to more than one culture or way of life. Bilinguals also appear to be better at learning other new languages. Clarisse spent her early childhood in Switzerland speaking French. At 6, she learned English. Later she learned Spanish, German, and, during three years living in Tokyo, Japanese. Now she has easily mastered several languages.
Question: According to Tamar Gollan, _ .
Options: (A) knowing two or more languages can improve children's skills (B) the more languages children know, the better they will be (C) children had better not take vocabulary tests (D) bilingual education is not always good to children
