Monday 2nd January

I am in a small village in the Carpathian Mountains, north of Bucharest, the capital of Romania. I’ve come to see the brown bears, which come to the villages at night to look for food. They walk 20 kilometres a night to get here. A farmer told me that some of his sheep have been killed by bears. But this is unusual. Usually, the bears just take bits of food which people have thrown away. Tonight I hope I’ll see them.

Tuesday 3rd January

Last night I waited with a group of tourists and as it grew dark, we saw the huge black shapes of bears. It seems the bears don’t go for people, unless they are attacked first. They were not afraid of the tourists, who took photos of them. Those clever bears knew where to go for their dinner. They jumped straight into the rubbish, where there was lots of food which people had thrown away.

Wednesday 4th January

Although it’s wonderful to see the bears in the village, it can only mean one thing: their habitat is disappearing. They would prefer to stay hidden in the mountain forests, but the trees have been cut down for firewood. So they cannot find enough food any more.

Thursday 5th January

Today I met the head of the Carpathian Animal Protection Group. He says that there are only about 2,500 bears left, and is worried that they will soon become extinct. Rich people from other countries pay a lot of money to come and shoot the bears for sport. The poor people from these villages need the money. But perhaps they could make more money from the tourists who want to come just watch the bears; and this would continue in the future. Once the bears are all dead, the tourists will stop visiting the village. But if the bears keep visiting the villages, then, perhaps, so will the tourists.

1.The best title for this passage would be _____________.

A. Hungry Brown Bears B. Brown Bears in the Forest

C. Wandering Brown Bears D. Brown Bears—A Wonder

2.It is unusual to the writer that ________________.

A. the brown bears like to be taken photos of.

B. the bears come out at night to look for food

C. the bears just take bits of food thrown away

3.The villagers could continue to earn money from the bears if _________.

A. they shot the bears for sport

B. people paid more money to kill them

C. more tourists came to see the bears

D. the villagers sold the bears’ skins to tourists

4.What will happen to the bears in the future?

C. They may keep eating rubbish.

D. They may be watched by visitors.

It seems that electronic devices just keep getting smaller. Scientists in the United States have announced the creation of the first transistor with only two dimensions(二维).

A transistor is a small electronic device that transfers or carries electronic current. Scientists hope these new 2D transistors will be used for building high-resolution(高分辨率)displays that need very little energy.

Two groups of scientists created these 2D transistors. They report that the transistors are only a few atoms thick.

Usually transistors are made with the element silicon(硅). Computer processors, memory chips, TV screens and other electronic devices contain billions of silicon-based transistors. But these very small electrical parts have certain limitations.

Dimitris Ioannou is an electrical engineering professor at George Mason University. He says the traditional transistor has been improved as much as it can be.He adds that researchers have been looking for new materials with special features and they want transistors to be seen through and soft.

“If the layers are very thin, the transistor can become flexible, so it doesn't have to be rigid(坚硬的), like it would be in a silicon chip. So people can think of applications like wearable electronics, television screens and other things,” said Ioannou.

These new transistors can also carry higher current. They also can move the current much faster than traditional transistors. This is important for high-definition screens.

Dimitris Ioannou says the scientific success could prove very useful in the future. "Now, how good and how useful it will be, it's still in the stage of research, but it certainly is an advance," said Ioannou.

1.Which of the following statements about the newly created transistor is TRUE?

A. They are expected to be used in high-resolution displays.

B. The transistors are made with the element silicon.

C. They are rigid, just like traditional transistors.

D. They have already been put into actual use.

2.What does the underlined sentence in Paragraph 5 mean?

A. The traditional transistors have been changed into two-dimensional ones.

B. Many of the traditional transistors have been improved over the years.

C. The traditional transistor has been developed to its fullest.

D. The traditional transistor has been developed quite well.

3.What is Dimitris Ioannou's attitude towards the creation of the new transistors?

A. Negative. B. Neutral.

C. Indifferent. D. Positive.

Make Your Brain Smarter

You know that eating a proper diet and getting plenty of exercise help make your body healthy and strong. But did you know that there are ways to make your brain healthier and smarter? Studies show that when the brain is forced to do something new, it creates new neural (神经的) pathways. 1.

● Limit your TV viewing.

Watching an average TV show requires very little brain power and brings the same result as neglecting (忽视) physical exercise. 2. If you watch TV, choose something educational and informative.

● Use your non-dominant (非支配的) hand.

If you are right-handed, use your left hand for everyday activities, or use your right hand if you are left-handed. Doing familiar things in a new way will cause your brain to create new neural networks. Brushing our teeth is something we do daily. 3. But maybe we should. Experts suggest that we can force the brain to work by changing things up and working with our non-dominant hand. So the next time you brush your teeth, open the tube, apply your toothpaste and brush with the opposite hand.

4.

Jump in the shower and shut your eyes. Even if you drop the soap—that’s okay. 5.Searching for the soap while feeling the textures (质地) with your eyes closed works. Using your fingers to make fine distinctions between objects or textures can reconnect the brain areas involved in touch, suggests Larry Katz, a professor of neurobiology at Duke University Medical Center and author.

A. Shower with your eyes closed.

B. Smart people rarely follow a set pattern.

C. The more pathways you have, the smarter you will be.

D. Use your different senses.

E. We really don’t put that much thought into it.

F. Put your brain to best use.

G. Your brain will become weak just as your muscles do.
