B

People tend to become more personal and hide less of themselves when using email. Researchers from Open University in Britain have found in a recent study that there are good reasons for this.
The team of researchers asked 83 pairs of students, all strangers to each other, to solve a problem. They had to discuss this question: If only five people in the world could be saved from a world disaster, who should they be? The pairs of students had to talk over the problem either face to face or by computers. Dr. Johnson said, “They told their partners four times as much about themselves when they talked over the Internet as when they talked face to face. When the computers were fitted with cameras so that students could see each other, this limited the personal side of the conversation.”
Generally the information was not extremely personal. It was mainly about things such as where they went to school, or where they used to live. But some students discussed their love stories, and personal childhood experiences.
Dr Johnson believes that emailing encourages people to focus on themselves. And when they do this, they become more open, especially if there are no cameras. “If you cannot see the other person, it becomes easier to talk about yourself. This is because you are not thinking what the other person is thinking of you. So emailing has become the modern way of talking,” said Dr. Johnson. However, this style of talking is not entirely new. “In the 19th century people started to use the ‘telegraph’ to communicate. Now the same kind of thing has happened and people ended up speaking more freely.”
Dr. Johnson thinks that emailers need to know about these effects of emailing, especially when they start work in a company. “ If you don’t know about it, you could find yourself saying more about yourself than you wanted to.”

C. how to communicate at work                         D. how to discuss and solve a problem

Trees should only be pruned (修剪) when there is a good and clear reason for doing so and , he number of such reasons is small . Pruning involves the cutting away of overgrown and unwanted branches , and the inexperienced gardener can be encouraged by the thought that more damage results from doing it unnecessarily than from leaving the tree to grow in its own way .
First , pruning may be done to make sure that trees have desired shape or size . The object may be to get a tree of the right height , and at the same time to help the growth of small side branches , which will thicken its appearance or give it a special shape . Secondly , pruning may be done to make the tree healthier . You may cut out diseased or dead wood , or branches that are rubbing against each other and thus cause wounds . The health of a tree may be encouraged by removing branches that are blocking up the center and so preventing the free movement of air .
One result of pruning is that an open wound is left on the tree and this provides an easy entry for disease , but it is a wound that will heal (愈合) . Often there is a race between the healing and the disease as to whether the tree will live or die , so that there is a period when the tree is at risk . It should be the aim of every gardener to reduce that risk of death as far as possible . It is important to make the area , which has been pruned , smooth and clan , for healing will be slowed down by roughness . You should allow the cut surface to dry for a few hours and then paint it with one of the materials available from garden shops produced especially for this purpose . Pruning is usually done in winter , for then you can see the shape of the tree clearly without interference (妨碍) from the leaves and also it is very unlikely that the cuts you make will bleed . If this does happen , it is , of course , impossible to paint them properly .
71．Why should running be done ?
A．To make the tree grow taller .               B．To improve the shape of the tree .
C．to get rid of the small ranches .             D．To make the small branches thicker .
72．Trees become unhealthy if the gardener         .
A．To help a wound to dry .
B．To cover a rough surface .
C．damages some of the small side branches
D．Allows too many branches to grow in the middle
73．Why is a special material painted on the tree ?
A．To help a wound to dry .                      B．to cover a rough surface .
C．To make a wound smooth .                   D．To prevent disease entering a wound .
74．A good gardener prunes a tree         .
A．several times throughout the year         B．as quickly as possible
C．occasionally when necessary                 D．regularly every winter
75．What was the author’s purpose when writing this passage ?
A．To discuss different methods of pruning .
B．To introduce some common knowledge of pruning .

An Experiment
Materials: Newspaper, ‘ACE’ hardware ruler (1/8 “think”), a flat table.
Purposes: We’ll show that there is air pressure pushing on us, from every direction while we’re on this Earth.

Procedure:First put a thin ruler on a flat table with a little
less than half of it hanging off the edge of the table
(see the drawing below). Next place a sheet of newspaper
over the ruler flat against the table. Make sure to have
as little air as possible under the paper so that the fold line of the newspaper is at the ruler. Then quickly strike the end of the ruler hanging off the edge of the table. If you strike it quick enough, the ruler will break near the table edge.
What’s going on?
The Earth is covered in a layer of air that is nearly 80 miles thick and at sea level (the bottom) exerts or ‘pushes’ hard almost 15 pounds of pressure per square inch. That means that a full sheet of newspaper laid out flat has nearly 9,300 pounds of air above it.
When you break the ruler above, you are able to break it because of the "heavy" air pushing down on the paper while you quickly strike the ruler. At first the table is pushing back on the paper, and if you move the ruler quick enough, other air around the edges of the paper can"t get under the paper fast enough, so you are trying to lift that 9,300 pounds with the ruler! Some air gets under the paper, but not enough, so the ruler breaks.
1．By doing the experiment, we may realize         .
A．that air exits everywhere
B．why there are directions
C．that we live with air pressure
D．how air helps on the earth
2．How many steps are there in this experiment?          .
A．2      B．3       C．4       D．5
3．The underlined word “exert” probably means       .
A．cover completely            B．advocate actively
C．influence gradually D．press heavily
4．The ruler breaks under a quick strike mainly because of          .
A．the air pressure on the newspaper   B．the heavy weight of the newspaper
C．the heavy weight of the flat table    D．the strong power used on the ruler

It was Thanksgiving morning and in the crowded kitchen of my small home I was busy preparing the traditional Thanksgiving turkey when the doorbell rang. I opened the front door and saw two small children in rags(破旧衣服) huddling together inside the storm door on the top step.
"Any old papers, lady? " asked one of them.
I was busy. I wanted to say "no" until I looked down at their feet. They were wearing thin little sandals(凉鞋), wet with heavy snow.
“Come in and I"ll make you a cup of hot cocoa.”
They walked over and sat down at the table. Their wet sandals left marks upon the floor. I served them cocoa and bread with jam to fight against the cold outside. Then I went back to the kitchen and started again on my household budget.
The silence in the front room struck me. I looked in. The girl held the empty cup in her hands, looking at it. The boy asked in a flat voice, "Lady, are you rich? "
"Am I rich? no!"
I looked at my shabby slipcovers(旧家具套). The girl put her cup back in its saucer (茶托;浅碟)carefully and said, "Your cups match your saucers." Her voice was hungry with a need that no amount of food could supply. They left after that, holding their bundles of papers against the wind. They hadn"t said "Thank you." They didn"t need to. They had reminded me that I had so much for which to be grateful.
Plain blue china(瓷的) cups and saucers were only worth five pence. But they matched.
I tasted the potatoes and stirred the meat soup. Potatoes and brown meat soup, a roof over our heads, my man with a good steady job--these matched, too.
I moved the chairs back from the fire and cleaned the living room. The muddy prints of small sandals were still wet upon my floor. Let them be for a while, I thought, just in case I should begin to forget how rich I am.
1. Why did the writer let the children in?
A. She showed great pity on them.
B. She wanted to sell old papers.

A. she saw that the lady"s room was comfortable
B. she saw the cups matched the saucers

C
Not many years ago, some American farmers began to complain about hawks(鹰). The hawks were killing chickens. The farmers did not know what to do. They went to the government officials and asked for help.
The officials said, “ We’ll pay you for each hawk you kill.” The farmers began to kill the hawks. Many hawks were killed, but the farmers now had another problem. The field mice were growing in number and they were eating up the farmers’ corn. Hawks eat not only chickens but also field mice. They eat more field mice than chickens. But if the farmers had known that, they would not have upset(打乱) the balance of nature. In one part of the USA, there are deer which eat a kind of wild rose. The deer are eaten by mountain lions. The number of deer, mountain lions, and wild rose does not change much if people stay away from them. If there are too many deer, mountain lions will increase rapidly in number and kill many deer. If there are too many mountain lions, there will be fewer deer and there will be more roses.
It is always necessary for us to keep the balance of nature. The government once killed almost all the mountain lions to protect the deer. Soon there were so many deer that they ate up all the wild roses. Then they began to eat the green leaves of young trees which were important to the farmers.
So the farmers protected their trees from the deer. The deer had nothing to eat, and many of them died.
The government learned a valuable lesson from nature.
44. What had happened after the hawks were killed?
A. People wouldn’t worry about their chickens.
B. The number of the field mice became too large.
C. The number of the field mice became small.
D. The field mice were eating up the farmers’ corn.
45. Why did American people have to protect their trees?
A. Because the mountain lions destroyed the trees.
B. Because there were so many deer that they began to eat the green leaves.
C. Because they wanted the trees to grow well.
D. Because the trees are more important than the deer.
46. What can we learn from the article?
A. We must keep the balance of nature.
B. We must not kill any animals.
C. we must feed the hawks with our corn to keep the balance of nature.
D. Both A and B.
