Anyone who has ever played the game of Tetris (俄羅斯方塊) knows the game’s surreal ability to spill into real life. After you shut off the game, you still see those Tetris blocks falling in your mind. You're grocery shopping and find yourself thinking about rearranging items on grocery shelves. Your mind continues to play the game, even when you're physically not.

Robert Stickgold, a Harvard professor, noticed something similar after a day hiking a mountain. That night, he dreamt he was still going through the motions of mountain hiking. Curious about this, he tried something: he got a group of college students of various skill levels to play Tetris and let them sleep in the Harvard sleep lab.

Over 60% of the students, including those who suffered from amnesia (健忘癥), reported dreams of images of Tetris pieces falling, rotating (旋轉(zhuǎn)), and fitting together. Interestingly, half the Tetris expert students reported such Tetris dreams, while 75% of the beginners did.

A study found that playing Tetris can grow your brain and make it more efficient. Adolescent girls played the game for an average of 1.5 hours a week over three months. The cerebral cortex (大腦皮層) of the girls grew thicker, while brain activity in other areas decreased. Richard Haier, who had found that there was a "Tetris learning effect", in which the brain consumed less energy as mastery of the game rose, concluded, "The brain is learning which areas not to use."

Haier's study showed that as the girls practiced playing the game, nerve cells made connections, communicating through synapses (a synapse is a connection between two nerve cells). When you learn something, you change those connections. Every time you reactivate(激活) a circuit, synaptic efficiency increases, and connections become more durable and easier to reactivate. Stickgold says sleep plays a role in this memory process.

So to sum up, whenever you do specific tasks over and over again, they take up less of your brain power over time. And that’s pretty amazing.

Children who spend more time outdoors may have a lower risk of becoming nearsighted, new research suggests.

In the study, researchers looked at about 1,900 schoolchildren. The scientists found that the kids who had been instructed to spend more time outdoors over three years were 23 percent less likely to develop nearsightedness during this time than those who had not been instructed to spend more time outdoors. Moreover, among the kids who did become nearsighted during the study, the degree to which their eyesight worsened was slightly smaller among those who spent more time outdoors.

The researchers selected six schools and required the children, whose average age was 7 at the start of the study, to attend one additional 60-minute class of outdoor activities during each school day for three years. The parents of these children were also encouraged to engage their children in outdoor activities after school, especially during weekends and holidays. The other half of the children, from another six schools, continued their usual activity patterns. After three years, 30.4 percent of the kids in the intervention(干預(yù)) group had become nearsighted, compared with 38.5 percent of the kids in the other group.

It is not clear exactly why spending more time outside would benefit children’s eyesight, the researchers said. However, some research has suggested that the higher levels of light intensity found outdoors may increase the release of the chemical dopamine(多巴胺) of the eye. In turn, dopamine is known to restrain（抑制） the type of growth in the eye that is associated with nearsightedness.

Based on the new results, the researchers recommend that children spend more time outdoors because of the potential benefits to their eyesight. However, it’s important to protect kids’ skin and eyes from UV light, which can be damaging.

1.What did the children in the intervention group do during each school day?

A. Attend an extra class of outdoor activities.

B. Continue to do their usual activities.

C. Spend one hour in doing eye exercises.

D. Participate in outdoor activities with parents.

2.What can be inferred about the chemical dopamine?

A. It can contribute to poor sight.

B. It can damage people’s brain.

C. It is beneficial to eyesight.

D. It means low levels of light intensity.

3.What may be discussed in the following paragraph?

A. How to design outdoor activities for kids.

B. How to prevent kids becoming nearsighted.

C. How to protect kids’ skin and eyes from UV light.

D. How to encourage kids to join in outdoor activities.

4.Which can serve as the best title for the passage?

A. The More Time Outdoors, the Better

B. Kids May See Better if They Play Outside

C. It’s Time to Engage Kids in Outdoor Activities

D. Researchers Found a Cure for Nearsightedness

How to Improve Vocabulary Fast

Your vocabulary refers to the words in a language you are familiar with. We should learn some ways to expand it.

Read every day. 1. Choose reading material that is slightly above your level and keep a dictionary with you to look up words you do not know.

2.. If you do not meet with an unfamiliar word in your daily reading, use your dictionary to search for one.

Learn the correct definition and pronunciation for each new word. Pronunciation is as important as definition because in order to add a word to your active vocabulary, you must be able to use it in speech.

Elaborate(詳盡闡述)on the meaning of the word. If you have just learned that the word “stubborn” , think about the neighbor who will not lend you his car. 3.

Use your new word in speech and in writing. E-mail your sister about how your cat is stubborn about sleeping on your pillow. 4. But the more you use it, the more fluent you will become in its use. Soon it will be a regular part of your active vocabulary.

Tell everyone you are trying to increase your vocabulary. Encourage them to ask you what your latest word is. 5.. The more you explain the meaning of a word to someone, the more likely you are to remember it.

A. Find a new word every day.

B. The vocabulary can be increased.

C. Your vocabulary contains the words you understand.

D. The more often you read, the faster your vocabulary can grow.

E. Or let them ask for the definition of a new word you have used.

F. Imagine him shaking his head, and think of him as “stubborn in his refusal”.

G. The first time you use a new word in speech it may seem strange.

A dam is a man-made structure built across a river. Most dams are built to control a river’s water flow, improve navigation and control flooding. However, some dams are built to produce hydro-electric power.

Hydro-electric power is produced as water passes through a dam, and into a river below. The more water that passes through a dam, the more energy is produced. Once a dam is built, a man-made lake is created behind the dam.

Electricity is produced by a kind of equipment called a turbine(水輪機). Turbines contain metal coils(線圈) surrounded by magnets(磁鐵). When the magnets move round rapidly over the metal coils, electricity is produced. Turbines are located inside dams. The falling water makes the magnets go around the coils.

Dams provide clean energy, but they can also harm the environment. Species that use rivers to reproduce are often hurt by dams. In the Northwest of the US, the population of fishes has dropped from 16 million to 2.5 million since hydro-electric plants were built on the Columbia River. Dams all over the world have hurt some species. 

The highest dam in the Unites States is located near Oroville, California. The Oroville Dam towers 230 meters and is more than a mile wide. This dam was built in 1968, 22 years after the Hoover Dam. The Hoover Dam, on the Nevada-Arizona border controls the Colorado river. It is 221 meters high and has 2.6 million hectare-meters of water.

The highest dam in the world is the Nurek Dam on the Vakhsh River in Tadzikistan, a country in central Asia. This dam is 300 meters tall.

1.Which of the following statements is NOT true according to the passage?

A. Some dams are built for controlling a river’s water flow.

B. Hydro-electric power is usually produced through a dam.

C. Dams can offer energy and they are harmless to the environment.

D. Generally speaking, where there is a dam, there is a man-made lake.

2.The third paragraph mainly tells us _____.

A. how hydro-electric power is produced

B. What a turbine is and how it works

C. how the magnets and the metal coils work

D. how the falling water passes through a turbine

3.The dam which controls the Colorado river is ____.

A. the Oroville Dam B. the Hoover Dam

C. the Nurek Dam D. the Vakhsh Dam
