We spend a quarter of our lives asleep. Sleep is necessary for the body to rest, yet our brains continue to process information. Studies have shown that students are more successful when they sleep after studying-instead of pulling all-nighters-because the brain reviews information learned. Similarly, dreaming is an opportunity to work out emotional problems and form thoughts and memories. About 25 percent of the time spent sleeping is spent in rapid eye movement, or REM, sleep. This type of sleep is known for when dreams occur, but it also helps energize the brain and body. Researchers have found two important factors regarding humans and sleep: basicsleep need and sleep debt. Basic sleep need is the amount of sleep we need to have regularly to perform at our best. Sleep debt is the loss of sleep. A few studies say that most adults function best with a basic sleep need of seven to eight hours a night. The problem is that sleep debt also factors in, just because that you meet your basic sleep needs a few nights of the week doesn't mean it cancels out the effects of one night's sleep debt. Of course, everyone is different and some people require more or less sleep than the standard basic sleep need. But the real problem lies in what lack of sleep does over the long period to people who either does not meet his or her body's needs or for one reason or another doesn't get enough regular sleep. It is more possible for these people to have motor vehicle accidents, weight gain and risk for heart disease or diabetes and may be at increased risk for psychological conditions such as depression or drug abuse. Sleeping too long also can be associated with depression and poor health. Which statement is TRUE according to the passage? A) Students will forget what they have learned if they go to sleep immediately after study. B) People may have an idea on how to solve an emotional problem if they have a dream. C) It's all right to have a night of sleep debt if you fulfill several days of basic sleep need. D) Sleeping as long as you can is considered to be good for your health and performance.

Ques: California, once regarded as a leader in the United States for its public higher education system, ranks next to the last in the U.S.for its number of adults with at least a high school diploma, according to the report, titled "California at the Edge of a Cliff," released by the California Faculty Association. Meanwhile, the state's investment in public higher education has dropped over the past three decades, and now ranks 22nd in the country.That's despite having the country's largest public higher education system, the report said. "It's a collapse ," said Thomas Mortenson, author of the report, who is an independent analyst living in Iowa and a senior scholar at the Pell Institute for the Study of Opportunity in Higher Education in Washington, D. C. "Ranking 49th out of 50 states is an indication that shows the quality of the state's educational has become much worse in recent decades." Mortenson said in the report.As of 2007, California ranked 14th in the United States in terms of college educated members of the workforce over 25 years of age, a drop from eighth place in 1981, the report showed. Mortenson said that California has never been the state of high status in education and economy while other states have made greater gains in building a college-educated workforce. The California Faculty Association is using the report's findings to criticize Governor Arnold Schwarzenegger's proposed funding cuts for education. Struggling with a 14.8-billion-dollar state budget deficit , Schwarzenegger has proposed a combination of sales tax increases, borrowing and major budget cuts, including cutting billions of dollars from the state's education budget. The reason why California has a lower rank in education is that _ . A) the number of adults has decreased recently B) the result of report has been published late C) the money to invest in education has been cut D) the progress in other states has been made

Ques: You can not see any object unless light from that object gets into your eyes. Some of the things you see give off light of their own. The sun, the stars, a lighted lamp are examples that can be seen by their own light. Such things are _ . Most of the things you see are not giving off light of their own. They are simply reflecting light that falls on them from the sun or some other luminous bodies. The moon, for example, does not give off any light of its own. It is non-luminous. You see it because sunlight falls on it and some of it reflects in our direction. So moon light is only second hand sunlight. When you look at a book, it sends to your eyes some of the light which falls on it, and you see the book. If light could be kept out from where you are so that there would be no light for the book to reflect, then you could not see the book even with your eyes wide open. Light travels so fast that the time in which it travels from the book you are reading to your eyes is so short as if there were no time at all. Light reaches us from the moon, which is about 380 000 kilometers away, in only a little more than a second. This article is probably from _ .
