It’s sad to learn that a whale has died in the ocean. However, that is not the end for the whale. It gives a lot to other sea animals after death.
When a whale dies, it quickly drops to the bottom of the ocean floor. There the whale’s dead body provides food and nutrients(营养) for deep-sea animals. The remains(残骸) can last(持续) for ten years and build an ecosystem called a whale fall — an “oasis(绿洲)” of life in the deep sea.
Chinese scientists found a whale fall for the first time in the South China Sea this year. The whale fall ecosystem can stay in the deep ocean because of great pressure and cold temperature there. They can stop the body from decomposing(分解) too quickly. The depth(深度) makes it hard for scientists to find the whale fall. There are less than 50 known whale falls in the world.
The whale fall in the South China Sea is about three meters long. Scientists have found several species(物种) near the whale fall. Some fish have started to eat the whale’s tail. A scientist named Xie Wei says the whale fall might be quite recent and needs long-term observation(观察). By studying the whale fall, scientists can better understand how sea ecosystems support life.
1.What does the whale’s dead body provide for deep-sea animals?
____________________________________
2.Where did Chinese scientists find a whale fall for the first time?
____________________________________
3.Why can the whale fall ecosystem stay in the deep ocean?
____________________________________
4.Are there any species near the whale fall in the South China Sea?
____________________________________
5.What does the passage mainly talk about?
____________________________________

Many people think of the brain as a mystery. They don’t know much about intelligence and how it works. When they do think about what intelligence is, many people believe that a person is born smart, average, or dumb—and stays that way in the whole life. But new research shows that the brain is more like a muscle(肌肉)—it changes and gets stronger when you use it. And scientists have been able to show just how the brain grows and gets stronger when you learn.
Everyone knows that when you lift weights, your muscles get bigger and you get stronger. A person who can’t lift 20 pounds when he/she starts exercising can get strong enough to lift 100 pounds after working out for a long time. That’s because the muscles become larger and stronger with exercise. And when you stop exercising, the muscles shrink(收缩)and you get weaker. That’s why people say “Use it or lose it!”
But most people don’t know that when they practice and learn new things, parts of their brain change and get larger a lot like muscles do when they exercise. Inside the cortex(皮层)of the brain are billions of tiny nerve(神经元)cells(细胞),called neurons. The nerve cells have branches connecting them to other cells in a complicated(复杂)network. Communication between these brain cells is what allows us to think and solve problems. When you learn new things, these tiny connections in the brain actually multiply and get stronger. The more you challenge your mind to learn, the more your brain cells grow. Then, things that you once found very hard or even impossible to do —like speaking a foreign language or doing algebra(代数)—seem to become easy after learning them for a period of time. The result is a stronger, smarter brain.
Scientists started thinking that the human brain could develop and change when they studied animals’ brains. They found out that animals that lived in a challenging environment were more “perspicacious”—they were better at solving problems and learning new things.
1.According to the first paragraph, .
A.the function(作用)of our brain is like that of the muscle
B.until now it’s impossible to explain the brain’s mystery
C.many people believe one’s intelligence is naturally determined(决定)
D.one’s brain grows stronger as the age increases
2.What is Paragraph 3 mainly about?
A.The complicated structure of the brain.
B.How changes in the muscles affect the brain.
C.The importance of the brain.
D.How the brain becomes stronger by learning new things.
3.What does the underlined word “perspicacious” in the last paragraph probably mean?
A.Strong. B.Smart. C.Popular. D.Active.
4.The paragraph that follows the passage will most probably talk about .
A.the differences between animals’ brains and humans’ brains
B.the relation between human brains and muscles
C.scientists’ findings about animals’ brains
D.how to make your brain smarter through self-development

In the days before electricity, people don’t worry much about sleep. They usually went to bed a couple of hours after sunset (日落) and woke at sunrise. After all, there wasn’t much to do in those days after the sun went down. But then came the electric light bulb (电灯泡). And now we have satellite television, the Internet,24-hour convenience stores, and longer hours at work. How much can we sleep? How much should we sleep?
Like it or not, many of us are sleeping less on average (平均). In 1910, most Americans slept 9 hours a night. That dropped to 7.5 hours by 1975. In 2002, a study by the National Sleep Foundation found that the average American got only 6.9 hours. The news is even worse for people who work the night shift. They sleep an average of just 5 hours.
Are we sleeping enough? Not if you believe in the old rule of eight hours of rest, eight hours of work, and eight hours of play. On the other hand, Norman Stanley, a British scientist who studies sleep, believes people’s sleep needs are different. Some people need as many as 11 hours, but others need as few as three. How much do you really need? “To find out,” he says, “simply sleep until you wake naturally, without the help of an alarm clock. That’s your sleep need.”
Meanwhile, other scientists and researchers are searching for new ways to keep us awake longer. Some are developing chemicals (化学药品) that are safer and more powerful than caffeine, the chemical found in coffee and tea. One experimental drug, CX717, kept laboratory monkeys working happily for 36 hours. Further developments may allow people to safely stay awake for several days straight. One group of researchers is studying a gene (基因) found in some fruit flies that lets them get by on one-third the usual amount of sleep. Another group is even working on an electric switch that immediately wakes up a sleeping brain.
The meanings of this research are huge. On the one hand, this could lead to a world where we work longer and longer hours with less and less sleep. On the other hand, if we needed less sleep, we would have more free time to travel, read, volunteer, and spend time with family.
1.How many hours did most Americans sleep a night in 1975?
A. 5. B. 6.9. C. 7.5. D. 9.
2.What can we learn from the passage?
A. People have got enough sleep. B. People will work longer hours.
C. Sleep time will be a big problem. D. Staying awake for long is possible.
3.What is probably the best title of the passage?
A. To sleep or Not to sleep? B. How can We Sleep Longer?
C. To Work or Not to Work? D. How Much We can Sleep?
