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. The best title for the passage is   _  . A) Why We Need Sleep B) REMSleep and Basic Sleep C) Sleep Causes Problems D) How Much Sleep We Need

Some places in the world have strange laws. It's important for you to know about them before going there. Whoever likes to chew gum  may have to leave Singapore. The government really wants to keep the city clean and will fine you for chewing gum. Before you leave for the United Arab Emirates you'd better make sure you aren't visiting during Ramadan . During that time you aren't allowed to eat or drink in public. Tourists have been fined up to $275 for drinking in public. Lovers spend so much time kissing each other goodbye at train stations that trains often start late. This law -- no kissing your lover goodbye at train stations - is rather old, and isn't in use today in France. In Thailand it's against the law to drive a car or motorcycle without a shirt on, no matter how hot it is. Punishments are different in different areas and can include warnings and tickets costing about $10. No joke -- the local police will stop you. Studies in Denmark have shown that cars with their headlights on are more noticeable by other drivers than those with their headlights off. Drivers there are required to leave their headlights on even during the day, or they may face a fine up to $100. Do you often buy things using coins? Don't do it in Canada. The Currency Law of 1985 doesn't allow using only coins to buy things. Even the use of the dollar-coin is limited  . The shop owner has the right to choose whether to take your coins or not. Make sure you know about these laws before your next trip. Better safe than sorry. What can we learn from the text? A) Kissing goodbye at train stations isn't allowed in France today. B) The Singaporean government cares a lot about its environment. C) Tourists in the United Arab Emirates shouldn't eat in public. D) You can turn your headlights off in daytime in Denmark.

You might think I'd have little in common with a camel, but we do share one useful skill: both of us can go for a very long time without water. Usually I start my day with a cup of tea, and then I might have a glass of water with my lunch and one with dinner, that's about a liter of liquid in 24 hours. It feels like plenty, but apparently it's not nearly enough. After years of suffering headaches and poor digestion I spoke to a neurologist about my regular headaches and a nutritionist about my poor digestion, and both told me I should be drinking up to three liters of liquid a day for my body to function at its best. I decided to conduct an experiment. What would happen if I drank the recommended amount every day for a month? The photograph of me taken the day I started this trial demonstrates perfectly and rather frighteningly what a lack of hydration does to a face. I am 42, but have to admit I look more like 52 in this picture, which is shocking. There are dark shadows under and around my eyes, which make me look exhausted, a profusion of wrinkles and strange reddish blotches, and my skin lacks any luster . It looks dead. Even my lips look shriveled . This is all classic evidence of poor hydration, apparently. Every system and function in our body depends on water. It flushes toxins from the vital organs, carries nutrients to cells, provides a moist environment for ear, nose and throat tissues, and eliminates waste. Not drinking enough means all these functions becomes damaged. So I decided to see how I would look and feel if I drank three liters of water every day for 28 days. The results were astonishing. Why did the author decide to drink the recommended amount of water? A) Because she was very fond of doing experiments. B) Because she was informed of the importance of drinking enough water. C) Because her doctors forced her to do it. D) Because she wanted to be cured of her stomachache.
