Winter begins in the north on December 22nd. People and animals have been doing what they always do to prepare for the colder months. Squirrels (松鼠), for example, have been busy gathering nuts from trees. Well, scientists have been busy gathering information about what the squirrels do with the food they collect.

They examined differences between red squirrels and gray squirrels in the American state of Indiana. The scientists wanted to know how these differences could affect the growth of black walnut (黑胡桃) trees. The black walnut is the nut of choice for both kinds of squirrels. The black walnut tree is also a central part of some hardwood forests.

Rob Swihart of Purdue University did the study with Jake Goheen, a former Purdue student now at the University of New Mexico. The two researchers estimate that several times as many walnuts grow when gathered by gray squirrels as compared to red squirrels. Gray squirrels and red squirrels do not store nuts and seeds in the same way. Gray squirrels bury nuts one at a time in a number of places. But they seldom remember where they buried every nut. So some nuts remain in the ground. Conditions are right for them to develop and grow the following spring. Red squirrels, however, store large groups of nuts above ground. Professor Swihart calls “death traps for seeds”.

Gray squirrels are native to Indiana. But Professor Swihart says their numbers began to decrease as more forests were cut for agriculture. Red squirrels began to spread through the state during the past century.

The researchers say red squirrels are native to forests that stay green all year, unlike walnut trees. They say the cleaning of forest land for agriculture has helped red squirrels invade Indiana. Jake Goheen calls them a sign of an environmental problem more than a cause.

A.find out the living conditions for squirrels

C.do something to get rid of squirrels

4.According to the passage, which of the following is true?

My house is made out of wood, glass and stone. It is also made out of software.

If you come to visit, you'll probably be surprised when you come in. Someone will give you an electronic PIN (个人身份号码)to wear. This PIN tells the house who and where you are. The house uses this information to give you what you need. When it's dark outside, the PIN turns on the lights nearest you, and then turns them off as you walk away from them. Music moves with you too. If the house knows your favorite music, it plays it. The music seems to be everywhere, but in fact other people in the house hear different music or no music. If you get a telephone call, only the nearest telephone rings.

Of course, you are also able to tell the house if you want something. There is a home control console (控制台), a small machine that turns things on and off around you.

The PIN and the console are new ideas, but they are in fact like many things we have today. If you want to go to a movie, you need a ticket. If I give you my car keys, you can use my car. The car works for you because you have the keys. My house works for you because you wear the PIN or hold the console.

I believe that ten years from now, most new homes will have the systems that I've put in my house. The systems will probably be even bigger and better than the ones I've put in today.

I like to try new ideas. I know that some of my ideas will work better than others. But I hope that one day I will stop thinking of these systems as new, and ask myself instead, "How will I live without them?"

1.What does the passage mainly discuss?

A. How to develop a new system.

B. The function of the PIN.

C. A home for the future.

D. Easy life in the future.

2.What's the purpose when the writer wrote the fourth paragraph?

A. To let readers know why his ideas are new.

B. To let readers know how special his house is.

C. To explain the importance of the PIN and the console.

D. To explain more easily what the functions of the PIN and the console are.

3.The writer's new house is different from ordinary ones mainly because _____.

A. it has been controlled by computers

B. you can make a telephone call anywhere

C. it has your favorite music following you

D. the writer is able to change his new idea into practice

4.What is the writer most likely to be according to the passage?

A. An IT expert. B. A famous doctor.

C. An idealist D. An experienced teacher.

Marek was a farmer who lived in a village far away. One day he became very ill, and everyone thought he would die. They sent for a doctor, who arrived two days later and examined the sick man. The doctor asked for a pen and some paper to write down the name of the medicine. But there was no pen or paper in the village, because no one could read or write.

The doctor picked up a piece of burnt wood from the fire. Using the wood, he wrote the name of the medicine on the door of the house. "Get this medicine for him," he said,"and he will soon get better."

Marek's family and friends did not know what to do. They could not read the strange writing. Then the village baker had an idea.
