Tuvalu, north of Fiji, is a tiny country in the Pacific Ocean.
Storms and huge waves are a constant threat and none of Tuvalu's nine little islands is more than five metres above sea level. Salt water is already entering the country's drinking water supply, as well as damaging plants that produce fruit and vegetable.It fears it will be swallowed up by the sea. Without urgent help, the country's days are numbered.
But Tuvalu is not the first place to face sinking into the sea. Venice, a historic city in Italy best known for its canals, has sunk about 24cm over the past 100 years. Experts say that it will have sunk another 20-50cm by 2050. A century ago, St. Mark's Square, the lowest point in the city, flooded about nine times a year. Nowadays, it happens more than 100 times.
While Venice is slowly sinking into the mud on which it stands, Tuvalu's rising sea level is caused by global warming.
The average global temperature has increased by almost 0.5 centigrade degree over the past century; scientists expect it to rise by an extra 1-3 degrees over the next 100 years.
Warmer weather makes glaciers melt, adding more water to the ocean. The warmer temperatures also make water expand, so it takes up more space, causing the sea level to rise. The sea level has risen about 10-25cm in the last 100 years.
People have been increasing the greenhouse gases in the atmosphere, such as CO2, through burning coal, oil and gas. This adds to the power of the greenhouse effect, making the planet even warmer.
Many scientists believe that, if the warming is not stopped, there will be huge climate changes. The sea level could rise by one metre this century.
Should this come true, millions of homes would be swallowed up by the sea and the world will be flooded with "climate refugees" looking for somewhere else to live.
小題1: We can infer from Paragraph 2 that ______.
A．Tuvalu is in danger of being swallowed up by the sea
B．a(chǎn)ll Tuvalu’s islands are about five meters above the sea level
C．drinking water in Tuvalu has been destroyed

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 .
小題1:．Why should pruning 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.
小題2:．Trees become unhealthy if the gardener__________.
A．giving a tree a special shape and a definite height
B．removing small side branches and making a tree look less thick
C．a(chǎn)llowing too many branches to grow in the middle
D．having a tree surrounded by many other trees
小題3:．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.
小題4:．A good gardener prunes a tree _________ .
A．several times throughout the year B．a(chǎn)s quickly as possible
C．occasionally when necessaryD．regularly every winter
小題5:．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 the snowy Tibet plateau, traditional elements have been mingled with modern life -- youths dressed in the latest fashion dancing "Guozhuang," office-ladies playing conventional Tibetan music while driving to work and Tibetan girls wearing superb folk costume displaying their nice figures.
"I used to go shopping or bar-hopping with my friends after work. But now I don't think it is advisable to continue following that living style," said Pasang, a young Tibetan girl who practices Yoga everyday at a fitness club in the eastern suburbs of Lhasa city.
Today, the conception to live in a healthy way has become more popular in Tibet's general public.
When the night falls, crowds of aged citizens dancing "Guozhuang," a traditional Tibetan group dance, to vigorous folk music can be seen in many residential communities.

Different from their elder generations, a swarm of teenagers play skateboard or roller-skating shuttle among groups of strollers on the squares in front of the Potala Palace and Norbulingka, the Dalai Lama's permanent residence.
The stylish dress, colored hairs, an earring on a single ear or an obscure tattoo -- all these signals have highlighted Tibet's younger generation's personality and their view on fashion.

The first and best of victories is for a man to conquer himself; to be conquered by himself is, of all things, the most shameful, says Plato. Self-control is at the root of all the advantages. Let a man give in to his impulses (沖動(dòng)) and feelings, and from that moment he gives up his moral freedom.
A single angry word has lost many a friend. When Socrates found in himself any temper or anger, he would check it by speaking low in order to control himself. If you are conscious of being angry, keep your mouth shut so that you can hold back rising anger. Many a person has dropped dead in great anger. Fits of anger bring fits of disease. Whom the gods would destroy they first make mad. Keep cool, says George Herbert, for fierceness (狂怒) makes error a fault.
To be angry with a weak man is to prove that you are not strong yourself. Anger, says Pythagoras, brings with folly(愚蠢) and ends with regret. You must measure the strength of a man by the power of the feelings he conquers, not by the power of those which conquer him.
Self-control is man’s last greatest victory.
If a man lacks self-control he seems to lack everything. Without it he can have no patience, no power to govern himself; he can have no self-confidence, for he will always be controlled by his strongest feeling. If he lacks self-control, the very backbone and nerve of character are lacking also.
小題1: What does the reader learn from the first paragraph?
A．The greatest victory for a man is to conquer everything except himself.
B．One’s moral freedom is based on the control of himself.
C．To control oneself is the most difficult in one’s life.
D．If a person is too stubborn, he will feel most shameful.
小題2: What is the correct interpretation of “Whom the gods would destroy they first make mad ”in paragraph 2 ?
A．If the gods want to kill you, they make you crazy first.
B．If you always lose your temper, you will soon be finished.
C．If you cannot control yourself, you will become crazy.
D．If you are mad, you will be punished by the gods.

A．the very backbone and nerve of character

No one knows yet the accurate number of lives which have been lost in this terrible fire. But reports suggest that it is more than one hundred.
A wall of fire fifty feet high and at least one hundred and fifty miles wide is now racing towards the forests and rich farmlands of southern Victoria. Towns less than one hundred miles from Melbourne will be in danger unless the wind changes. People are rushing excitedly into the streets. The police have warned them not to see the fire but many people are doing so.
The cause of the fire is unknown. No rain has fallen in this part of Australia for three months, and the hot, north-west wind from the great central desert is blowing at more than thirty miles an hour.
The firefighters are traveling to the fire by road, rail and air. But it is not easy to get there. Flames and fallen trees have cut off or blocked roads and railway lines. The thick smoke often prevents them from finding the air strips (飛機(jī)跑道).
It is said that the fire has brought the greater danger to the country since the Second World War.

It’s 2035. You have a job, a family and you’re about 40 years old. Welcome to your future life.     Getting ready for work, you pause in front of the mirror, “Turn red,” you say. Your shirt changes from sky blue to deep red. Tiny preprogrammed electronic（智能電子元件） is rearranged in your shirt to change its color. Looking into the mirror, you find it hard to believe that you are 40. You look much younger. With amazing advances in medicine, people in your generation may live to be 150 years old. You’re not even middle-aged.
As you go into the kitchen and prepare to pour your breakfast cereal into a bowl, you hear: “To lose weight, you shouldn’t eat that,” from your shoes. They read the tiny electronic code（電 子源碼）on the cereal box to find out the nutrition details. You decide to listen to your shoes. “Kitchen, what can I have for breakfast?” A list of possible food appears on the counter as kitchen checks its food supplies.
“Ready for your trip to space?” you ask your son and daughter. In 2005 only specially trained astronauts went into space—and very few of them. Today anyone can go to space for day trip or longer vacation. Your best friend even works in space. Handing your children three strawberries each, you add, “The doctor said you need these for space travel.” Thanks to medical advice, vaccination shots（防疫針） are a thing of the past. Ordinary foods contain specific vaccines. With the berries in their mouths, the kids head for the front door.
It’s time for you to go to work. Your car checks your fingerprints and unlocks the doors. “My office. Autopilot,” you command. Your car drives itself down the road and moves smoothly into traffic on the highway. You sit back and unroll your e-newspaper. The latest news downloads and fills the viewer. Looking through the pages, you watch the news as video films rather than read it.

   How men first learnt to invent words is unknown; in other words, the origin of language is a mystery． All we really know is that men, unlike animals, somehow invented certain sounds to express thoughts and feelings, actions and things, so that they could communicate with each other; and that later they agreed upon certain signs, called letters． These letters could be combined to represent those sounds, and which could be written down． Those sounds, whether spoken, or written in letters, we call words．
The power of words, then, lies in their associations---the things they bring up before our

Swimming is one of those activities that can be learned early in life. Little children can learn to swim as soon as they walk. In fact, you need the same skills in walking as in swimming. However, I believe that five is the best age to learn. By five or six, a child knows fear of water, a very important thing to know. It's wise to be afraid, to recognize true danger. Young ones understand that the water can sometimes be very dangerous.
To really benefit from swimming, every swimmer should learn, as soon as possible, these four basic strokes; butterfly, backstroke, Breaststroke, and crawl. I feel that one of these-the breaststroke-is different from the others, since some young swimmers use this stroke naturally, without any training.
In swimming there are certain rules every swimmer should follow:
1). Never swim alone! No matter how good you are in the water, don’t risk drowning by swimming alone. If you swim by yourself, with no life guards or friends with you, you may get into trouble.
2). Don't go beyond your abilities. Most swimmers know enough not to swim too far from the bank or the beach, Showing off by doing dangerous tricks is no good. Swim safely and you will continue to swim and alive.
3). Don't smoke. Swimming depends on a healthy body; good lungs are part of it.
4). Work at any activity that builds muscles.
小題1: Little children can learn to swim as soon as _____.
A．they can talk
B．they start walking
C．they have no fear of the water
D．they are five or six years old
小題2:The author believes that fear of water is_____.
A．stupidB．sensibleC．dangerousD．not smart
