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 (妨礙) 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.a(chǎn)s 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 .
C.To explain how trees develop disease .
D.To give practical instruction for pruning a tree .

  On Wednesday, the Chinese government, decided to increase its medical subsidies(補(bǔ)貼)  for farmers from 10 Yuan (US$1.23) to 20 Yuan (US$2.47) a head a year from 2006.
   As part of the country's healthcare reform programme, the co-operative rural (農(nóng)村)medical system was first introduced in 2003 to set up self-help among farmers on a voluntary basis.  Due to insufficient government input to finance hospitals that are mostly State-owned, the country's healthcare reform has largely turned out to be a failure, adding hugely to the financial burden on the public.
While everyone complains about quickly-rising medical costs, rural residents are suffering more than their urban(城鎮(zhèn)) cousins because of a lack of money, as well as not being able to enjoy high quality health services. At present, farmers earn on average only one-third of what urban residents make. Most of the country's medical resources are located in cities even though rural residents make up two-thirds of the population.
  Poor health conditions make it more difficult to help farmers get out of poverty; and poverty, in turn, refuses farmers the chance to improve their health. To end this vicious circle, policy-makers tried the co-operative medical system, with a small sum of central and local financial support for each rural participant. But the system has proved to be less than perfect. Due to the limited financial input, the programme still does not benefit the majority of farmers in a significant way. This has reduced many farmers' enthusiasm for participating. A high percentage of involvement is of course a precondition for such a system.
  The central government intends to expand the programme into a national medical system by 2008. Increasing government subsidies is a necessary step to make the co-operative medical system more attractive to farmers. But an increase of 10 Yuan for each participant is surely far from enough to perfect the system. The total cost is not particularly heavy compared to the rapid growth in government revenue(財(cái)政).
   Clearly, policy-makers are becoming increasingly aware of how urgent the narrowing of the development gap between rural and urban areas really is. Besides economic policies to push the rural economy, large amount of government investment on improving rural healthcare and education is badly needed.
1. Compared with that in 2006, what will be the rate of coming increase in China’s medical subsidies for farmers?
A. 100%               B. 50%                 C. 200%                      D. 150%
2. What is the reason for the failure in the country’s healthcare reform?
A. Bad management system.        
B. The government didn’t input enough money to support hospitals that are mostly
state-owned.
C. The health conditions in the country is too bad.
D. There are too many farmers that need medical care.
3. What is needed to narrow the development gap between rural and urban areas?
①. Large amount of government investment in economy.
②. Large amount of government investment on improving rural healthcare and education.
③. Economic policies to push the rural economy
④. A high percentage of farmers’ involvement in the medical system
⑤. A better management system
A. ①②③ B. ②③④             C. ①②③④⑤          D. ②③
4. Why are many farmers not enthusiastic in joining the co-operative medical system?
A. It doesn’t benefit most of the farmers in an effective way.
B. They cannot spare the needed money to join the programme.
C. They don’t believe in the system.
D. They don’t think it necessary.
5. What can be inferred from the last but one paragraph?
A. An increase of 10 Yuan in medical subsidies for each person is not enough.
B. The government can afford to increase the medical subsidies for farmers.
C. The government will get farmers of the whole country involved in a medical system by 2008. 
D. If the government increase subsidies, more farmers are likely to join the medical system.

請(qǐng)認(rèn)真閱讀下列短文,從短文后所給的A、B、C、D四個(gè)選項(xiàng)中,選出最佳選項(xiàng),并在答題卡上將該項(xiàng)涂黑。
A
In meditation(冥想),people sit quietly and focus their attention on their breath. As they breathe in and out, they attend to their feelings. As thoughts go through their minds, they let them go. Breathe. Let go. Breathe. Let go.
According to a recent study at the Insight Meditation Society in Barre, Massachusetts, three months of training in this kind of meditation causes a marked change in how the brain allocates attention. It appears that the ability to let go thoughts that come into mind frees the brain to attend to more rapidly changing things and events in the outside world. Expert mediators are better than other people at catching such fast-changing stimuli, like facial expressions.
The study provides evidence for changes in the workings of the brain with mental training. People can learn and improve abilities of all sorts with practice, everything from driving to playing the piano. The study has shown that meditation is good for the brain. It appears to reduce pressure and promote a sense of well-being.
In an experiment, 17 volunteers with no meditation experience in the experimental group spent three months meditating 10 to 12 hours a day. A control group also with no meditation experience meditated for 20 minutes a day over the same period. Both groups were then given the tests with two numbers in a group of letters. As both group looked for the numbers, their brain activity was recorded.
Everyone could catch the first number. But the brain recordings showed that the less experienced mediators tended to grasp the first number and hang onto it, so they missed the second number. Those with more experience gave less attention to the first number as if letting it go, which led to an increased ability to grasp the second number. This shows that attention can change with practice.
Just ask Daniel Levision, who meditated for three months as part of the study.” I am a much better listener,” he said. “I do not get lost in my own personal reaction to what people are saying.”
56. The underlined word “them” in Paragraph 1 refers to ________.
A. feelings         B. minds         C. people        D. thoughts
57. Meditations manage their daily tasks better because they ________.
A. are given less pressure                   B. allocate their attention better
C. have more stimuli for life                D. practice them more frequently
58. The study proves that ________.
A. meditation improves one’s health        B. brain activity can be recorded
C. human attention can be trained              D. mediators have a good sense of hearing

“High income is not as good as high age ,and high age is not as good as high spirits.”
Generally speaking , the rich are happier because money can purchase goods and services and it is the consumption(消費(fèi)) of these materials that increases one’s enjoyment of life . Especially nowadays , money seems to be one thing that drives the people around . “Human beings live for money while birds die for food.”—a well-known Chinese saying is quite quotable(適宜引用的)to interpret the present society.

Longevity(長(zhǎng)壽) is the very term that the people often use to pray for their dears and elders. So there are many books and theories that introduce the way of living longer. Dancing , jogging , dieting , even singing and shouting together are said to do good to one’s health.
Nevertheless , some people think that high spirits is vital to the quality of one’s life . If you are in high spirits , you’ll find everything pleasing and comfortable in life: warm sunshine , blue sky, white clouds , happy birds ,comfortable breeze , sweet smiles ,and so on . You seem to have the friends across the world. Your life will be happy at every moment. You will have a good health and can make more money if you live longer.

Football, to me, is more than just a game. I have probably learned more than valuable lessons from it than from school.
When I joined the team freshman year, I didn’t realize what I was getting into. Even though I had been playing since fourth grade and knew it was hard work, nothing would prepare me for the effort I would put into football that year. We worked all summer in the weight room and ran on the track to get in physical and mental shape before the season.
See, football is more of a mental sport than anything else, so running on the track wasn’t only about getting in shape . We would push our minds by running as hard as we could even if we felt like we were going to pass out. At the beginning, I was immature (幼稚的) and only thought of myself, sometimes even giving up when I was tired or hurting. Then after the third game I had a season-ending injury. Imagine working all summer and then only being able to play three games! I needed surgery on my arm and at least five months to recover.
After freshman year I decided that I would always give my best effort. Playing varsity (大學(xué)代表隊(duì)) football has taught me so much more than just what my tasks are on a particular play or how to block. I have learned to think about others first, and realized how important working hard is. Being with all my friends, even sweating and bleeding with them, really made us unite as a group of hard-working young men, who will succeed in life.
65. What is the text mainly about?
A. How the author dislikes the game of football.
B. When the author began to play football.
C. How the author has changed his attitude to football.
D. What sport the author likes best.
66. The author thinks football is ________.
A. just a game    B. of a mental sport    C. hard to pass out  D. not worth his effort
67. From the text we can infer ________.
A. the author joined the football team with a clear aim.
B. football only brought the author certain tasks
C. the author worked all summer to get ready for the season.
D. the author never lost heart when he met with difficulties.
68. In the third paragraph, the phrase “getting in shape” probably means ________.
A. becoming physically fit             B. designing the playground
C. losing weight                     D. measuring the track

“ Fire! Fire!” What terrible words to hear when one wakes up in a strange house in the middle of the night! It was a large, old, wooden house and my room was on the top floor. I jumped out of bed, opened the door and stepped outside the house. There was full of thick smoke.
I began to run, but as I was still only half-awake, instead of going towards the stairs I went in the opposite direction. The smoke grew thicker and I could see fire all around. The floor became hot under my bare feet. I found an open    door and ran into a room to get to the window. But before I could reach it, one of my feet caught in something soft and I fell down. The thing I had fallen over felt like a bundle of clothes, and I picked it up to protect my face from the smoke and heat. Just then the floor gave way under me and I crashed to the floor below with pieces of burning wood all around me.
I saw a doorway in fire, then I put the bundle over my face and ran. My feet burned me terrible, but I got through. As I reached the cold air outside, my bundle of clothes gave a thin cry, I nearly dropped it in my surprise. Then I was in a crowd gathered in the street. A woman in a night-dress and a borrowed man’s coat screamed as she saw me and came running madly.
She was the Mayor’s wife, and I had saved her baby.
1. The author saved the baby _____.
A. because he was very brave.
