Trees should only be pruned (修剪) when there is a good and clear reason for doing so and , the 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 clean, 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 .

That “Monday morning feeling” could be a crushing pain in the chest which leaves you sweating and gasping for breath. Recent research from Germany and Italy shows that heart attacks are more common on Monday mornings and doctors blame the stress of returning to work after the weekend break.
The risk of having a heart attack on any given day should be one in seven, but a six-year study helped by researchers at the Free University of Berlin of more than 2,600 Germans showed that the average person had a 20 percent higher chance of having a heart attack on a Monday than on any other day.
Working Germans are particularly not protected against attack, with a 33 percent higher risk at the beginning of the working week. Non-workers, by comparison, appear to be no more at risk on a Monday than any other day.
A study of 11,000 Italians proved 8 am on a Monday morning as the most stressful time for the heart, and both studies showed that Sunday is the least stressful day, with fewer heart attacks in both countries.
The findings could lead to a better understanding of what is the immediate cause of heart attacks, according to Dr Stefan Willich of the Free University. “We know a lot about long-term risk factors such as smoking and cholesterol（胆固醇）but we don’t know what actually causes heart attacks, so we can’t give clear advice on how to prevent them,” he said.
Monday mornings have a double helping of stress for the working body as it makes a rapid change from sleep to activity, and from the relaxing weekend to the pressures of work.
“When people get up, their blood pressure and heart rate go up and there are hormonal（内分泌）changes in their bodies,” Willich explained. “All these things can have an unfavourable effect in the blood system and increase the risk of a clot（血凝块）in the arteries（动脉）which will cause a heart attack.”
“When people return to work after a weekend off, the pace of their life changes. They have a higher workload, more stress, more anger and more physical activity,” said Willich.
．Monday morning feeling, as this passage shows, .

A．is not so serious as people thought

B．is harmful to working people in Germany and Italy

．If the researchers give us some advice to avoid Monday morning feeling, what might it be?

A．Stop working on Monday	B．Create a pleasant working environment
C．Get up late on Monday morning	D．Go to work with a doctor

.Which of the following is true according to the passage?

A．The risk of having heart attacks on Monday mornings is the same as on any other day of the week to non-workers

Joanne was stuck in a traffic jam in central Birmingham at 5：30 and at 6：30 she was expected to be chairing a meeting of the tennis club. At last, the traffic was moving. She swung quickly racing to her house. As she opened the door, she nearly tripped over (被绊倒)Sheba.
“Hey, Sheba,” she said, “I've got no time for you now, but I'll take you out as soon as I get back from tennis club.” Then she noticed Sheba seemed to be coughing or choking. Obviously, she could hardly breathe. Immediately, Joanne realized she would have to take her to the vet (兽医).
When she got there, the vet was just about to close for the day. Seeing the state of Sheba, Dr. Sterne brought her quickly into his office.
“Listen, doctor, I'm really in a rush to get to a meeting, can I leave her with you, and go and get changed? I'll be back in ten minutes to pick her up, and then I'll take her on to the meeting with me. Is that OK?”
“Sure.” said the doctor.
Joanne made the quick trip back to her house in a couple of minutes. As she was once moreentering the hallway, the phone by the door began to ring.
“This is Dr. Sterne,” said an anxious voice. “I want you to get out of that house immediately, ”said the doctor's voice. “I'm coming round right away, and the police will be there any time now. Wait outside!”
At that moment, a police car screeched (发出尖锐的声音)to a stop outside the house. Two policemen got out and ran into the house. Joanne was by now completely confused and very frightened. Then the doctor arrived.
“Where’s Sheba? Is she OK?” shouted Joanne.
“She’s fine, Joanne. I took out the thing which was choking her, and she’s OK now. ”
Just then, the two policemen reappeared from the house, half-carrying a white—faced man, who could hardly walk. There was blood all over him.
“My God, ” said Joanne, “how did he get in there? And how did you know he was there?”
“I think he must be a burglar.” said the doctor. “I knew he was there because when I finally removed what was stuck in Sheba’s throat：it turned out to be three human fingers.”

In Colombia, there are some unwritten rules that people are used to. These rules are not officially established, but people do respect them. For example, on a bus, a person keeps a distance from another person, and people don’t like to touch each other. Many people come to work late because they prefer to wait for another bus if the first one is too crowded. They don’t want to have to stand too close to another person, or maybe they are afraid of starting a conversation.
A friend of mine in Colombia once said his mom got angry because he came home late, so he asked her, “Mom, what do you think of most people arriving at their jobs so late?” That gave her the answer to her question since everyone knows no one wants to get on a bus that is too crowded. His mother realized at that moment that customs have a big influence on a person’s life.
Sometimes, people don’t like to make any kind of conversation or make eye contact(接触) with others. For example, when they are in line at a bank, they prefer to look up or down rather than look at other people.
Moreover, people usually look down when they are in an elevator. Not only on a bus, in line at a bank, and in an elevator do people usually avoid talking to other people, but also in the streets when they are walking, they prefer to look down and to avoid contact with others.
