Dust storms are violent and mostly unpredictable. They can cause property damage, injuries, and deaths, so it’s necessary to know what to do when you come across them.
     Watch out for dust storm warnings. Dust storms are most likely to occur on hot summer days, so listen to the local TV or radio broadcasts before traveling in hot, dry conditions, and consider changing or giving up your trip if dust storms are predicted. Roadside signs may also be able to warn you of dust storm danger.
     Be prepared. If you are in a storm-prone area, carry a mask(口罩) to keep out small dust particles (顆粒), and take eye protection to protect your eyes. A supply of water is also necessary.
     Go beyond the storm. If you see a dust storm from some distance, and you are in a vehicle, you should try to escape from it. Some dust storms can travel at more than 75 miles per hour, but they frequently travel much slower. However, it is not advisable to put yourself at risk by driving at high speed.
     Stay inside. Do not move about in a storm, as you will not be able to see hidden risks in your path. So if you’re in a house, stay inside.
     Protect yourself from flying objects. Cover as much of your body as possible. A dust storm’s high wind can carry heavy objects. If you find yourself without shelter, try to stay low, close to the ground, and protect your head with your arms, a backpack or a pillow.
小題1:What does the underlined sentence in Paragraph 4 mean?
A．Dust storms usually travel much slower than vehicles.

Active listening is an essential skill in learning. It is when you listen carefully to make sure you understand and learn the information that is being conveyed.   1   Here are some things which can help you to listen actively.
Listen for the main point and major subpoints(次要點(diǎn)). Don’t just write everything down. Listen carefully and make sure you understand what the purpose of this lecture is. As you take down notes, keep the main point in mind and make sure you understand how these notes are related.
Listen for an organizational structure. Listen carefully to figure out how the ideas are organized and they will make more sense.
Pay attention to organizational cues（暗示）.   2  Pay close attention to the introduction, as it will probably indicate how you should organize your notes. If the lecture begins with, “ Today, I’m going to talk about three conflicts in the Middle East,” then you have a good idea of what’ s going to follow. Listen for “signpost” words to indicate a transition for one point to the next, such as “next” and “finally” and numerical signposts like “first” or “third”.
Listen with your eyes.    3  Watch the teacher and be aware of how he or she uses hand gestures, eye contact and other body language to convey points.

If you get a cellphone call, your sleeve(袖子) will soon be able to answer it. If you want to know how far you’ve run, your trousers will be able to tell you. Can’t decide what to wear? Wish your clothes were smart enough to decide for you? A new computer science technology may be able to help your clothing to do just that.
Mark Jones, a computer scientist, says, "We view electronic textiles (電子紡織品) as, sort of, where computing meets the fabric (編織品)."
This high-tech marriage is bringing up the wearable computers, like trousers that can interpret movement and let a computer know your every move.
A loom (織布機(jī)) helps make the wires and fabric together. Then special equipment in the fabric can measure the speed. Signals are then sent from the trousers to a computer to show the process.
Tom Martin also says, "E-textiles are a way for us to build wearable computers that look like normal clothing and can fit in fully with the environment."
Researchers also hope wearable computers will help save lives. "We will be able to tell what activity a person is doing. That sort of information is highly valuable when we’re trying to monitor someone with a long-term illness such as heart disease," Jones says. Monitoring your every step is something that clever clothing can do a little easier. Researchers plan on developing more smart clothes to integrate computers into shirts, hats and gloves.
小題1:What does the underlined word "marriage" refer to in the passage?
A．The special equipment in the fabric used to measure the speed of our movement.
B．The unity（結(jié)合）of fabric and computing materials to make smart clothes.
C．Wearable computers which fit in with the environment.
D．The influence of electronics and computer science technology.
小題2:How will smart clothes be able to know the wearer’s every movement?
A．There are the wires and fabric together.
B．There are signals in the smart clothes.
C．The computer built into them will control their every movement.
D．The clothing will have special equipment fixed into the fabric.
小題3:The reason that people need smart clothes is that __________.
A．people are too lazy to decide what to wear
B．scientists want to prove their intelligence
C．smart clothes can provide information about the wearer’s health
D．smart clothes are as cheap as normal clothes
小題4:What is the best title for the passage?
A．Connecting Clothes with High Technology
B．New Ways to Discover Illnesses Early

Scientists are making new studies of color and its effects on our health. They have known for a long time that the color of a room or the color of the light in it can affect our feelings and emotions. Many prisons and hospitals have at least one room that is painted pink. Officials have found that light and color can produce physical changes in our bodies.
Professor Falfan worked with a group of 9 disabled children at school in Albert. Two of the children were blind. The other seven had normal sight. The scientists changed the color of the school room, then looked for changes in blood pressure, heart beat and breathing rate. The effects of color changes were the same for the blind children as for those with normal sight. Their blood pressure dropped from about 120 to 100. Similar changes were reported in heart-beat and the breathing. The children also were calmer and less excited. Then the colors of the room were returned to orange and white. Blood pressure, heart-beat and breathing rate went up and the children became excited again.
Professor Falfan said different colors produce different levels of light energy. He said the differences seem to affect chemicals in the brain that carry messages from nerve to nerve and from nerve to muscle.
小題1:Light and color can affect________.
A．only one’s feelings and emotions
B．one’s energy
C．one’s mental changes
D．one’s heart-beat, brain activities, blood pressure, feelings and emotions
小題2:The color of pink had a calming effect, that is to say, the color affects __________.
A．the chemicals in the brainB．the eyes
C．the skinD．the muscle

小題5:After reading the passage we can conclude that ________.
A．blind people can be affected by colors, too
B．one’s heart will beat fast in a colorful room than in a white room
C．the chemicals in the brain change with feelings and emotions
D．if one’s blood pressure drops, his breathing will get slower and slower

Do you know blood types?
Special care must be taken in selecting new blood for a badly injured person, who would be killed by the transfusion (輸血) if the blood is too different from his own.
There are four basic types of blood A. B. A B. and O. Blood type, like hair and height, comes from parents. Basically, A and B can not be mixed. AB, sometimes called the universal recipient (萬能受血者), may receive A or B,. O type, often called the universal donor (萬能輸血者), gives his blood to any other group. Patients usually receive nothing, but salt or plasma (血漿) until their blood can be matched as exactly as possible in the blood bank of a hospital. There is a relationship between your blood type and your nationality (國籍). Among Europeans, about 42 % have type A while 45 % have type O. The fewest is the type B.
小題1:Which of the following show the correct relationship in blood transfusion ("→"means giving blood to...)?

To master a language one must be able to speak and understand the spoken language as well as to read and write．Lenin and his wife translated a long English book into Russian but when they went to England in 1902, English people couldn't understand a word Lenin and his wife said, and Lenin and his wife couldn't understand what was said to them．This shows the importance of spoken language．
Speaking, of course can't go without listening．If you want to pronounce a word correctly, first you must hear it correctly．The sounds of Chinese and English languages are not exactly the same．If you don't listen carefully, you'll find it difficult or even impossible to understand the native speakers．
Well, what about writing﹖ Like speaking, it's to exchange ideas．People usually use shorter words and shorter sentences in their writing．
The important thing is to make your idea clear in your mind and then to write it in a clear lively language．
Chinese students read too slowly．If you read fast, you understand better．If you read too slowly by the time you have reached to the end of a page you have forgotten what the beginning is about．When you meet with new words don't look them up in the dictionary．Guess the meaning to form the context. You may not guess quite correctly the first time but as new words appear again and again in different context their meaning will become clearer and clearer. If you look up every word you'll never finish a book．
Students of a foreign language need a particular knowledge, the knowledge of the life, history and geography of the people whose language they're studying. They should study those subjects in the foreign language not only in translation．In this way one can kill two birds with one stone: learn a foreign language and get some knowledge of the foreign country at the same time．
小題1:In England Lenin        ．
A．could be understood by Englishmen
B．could understand Englishmen
C．a(chǎn)nd Englishmen couldn't understand each other

People often hear each others' voices without ever seeing the faces they belong to. "Nowadays we are talking away on the phone without meeting people," says Seung-Jae Moon. And from business conference calls to chat lines, people often imagine they would recognize the speaker if they saw him or her. Seung-Jae Moon, a linguist of Korea found that, under certain conditions, they're actually right.
Moon decided to see just how close those mental pictures match up with reality and if there was any relation to how people speak rather than what they are saying. He recorded 16 Koreans, half men and half women, reading the same passage, and took a full-body photo and head shot of each speaker. Then he played the tapes for 361 Koreans and 173 Americans who did not speak Korean and asked his subjects to match up voice and picture. The Korean participants viewing full-body photos were quite perceptive. A majority linked 6 of the 8 women to the correct voice and did so for 5 of the 8 men. With the Korean group shown only faces, accuracy plummeted, but more than 20 percent of the subjects selected the same incorrect picture. The Americans showed no accuracy in matching the foreign voices to photos, but they too were consistent in their errors. That disconnection reveals conflicting ideas of physical and vocal beauty. Moon asked people to pick a favorite face and voice. Seventy percent of the Koreans picked one voice, but there was no agreement on a face. Americans didn' t agree on either count. And over 65 percent of both Koreans and Americans did not match their favorite face with their favorite voice.
Moon hopes to use software to break voices into components like pitch and hoarseness to narrow down which elements trigger certain mental pictures. "If we can map which characteristics of the voice triggers what kind of linage, and it doesn't matter whether that image is the right or wrong one of the actual speaker, then we can create an image through voice,' he says. That capacity could help to create computer-synthesized voices tailored to conjure up specific associations — audio books for children that inspire motherly visages, or warning alerts that bring to mind a stern police officer.
小題1:People often think that they would ______ the speaker when they saw the speaker.
A．understandB．recognizeC．likeD．surprise
小題2:Moon decided to do the experiment to ______.
A．see how close mental pictures match up with reality
B．how people speak
C．see if there was any relation to how people speak rather than what they are saying
D．both A and C
小題3:He asked ______ Korean women to speak and recorded their voices.
A．12B．16 C．8D．10
小題4:______ were more perceptive in recognizing full-body photos.
A．The KoreansB．The American women

Water is very important to living things. Without water there can be no life on the earth. All animals and plants need water. Man also needs water. We need water to drink, to cook our food and to clean ourselves. Water is needed in offices, factories and schools. Water is needed everywhere.
There is water in seas, rivers and lakes. Water is found almost everywhere. Even in the desert part of the world, there is some water in the air. You can not see or feel it when it is a part of the air. The water in the seas, rivers and lakes is a liquid, the water in the air is a gas, and we call it water vapour (蒸氣).
Clouds are made of water. They may be made of very small drops of water. They may also be made of snow crystals(結(jié)晶體). Snow crystals are very very small crystals of ice. Ice is frozen water. It is a solid. There can be snow and ice everywhere in winter.
Water may be a solid or a liquid or a gas. When it is a solid, it may be as hard as a stone. When it is a liquid, you can drink it. When it is a gas, you can not see or feel it.

The Peppered Moth, a kind of insect(昆蟲), is found in England. It is light brown in colour and likes to settle(棲息) on trees which are also light brown. This makes the moth difficult to be seen and birds are less likely to notice and eat it.
But with the development of industry(工業(yè)) , smoke from factories began to reach the trees where the moth settled. It made the trees blacker. Then something very strange took place: in industrial areas, the Peppered Moth began to change colour. It became darker as well. Though the change took several years, some scientists soon notice that newly-born moths were a little darker than usual.
A scientist with the name Kettlewell decided to make a careful study of this phenomenon(現(xiàn)象). He marked some of the light moths and some of the darker ones, and set them free in the woods near Bermingham, an industrial city. Later, he recaptured(重新捕獲) as many as the marked moths as possible. The results were as follows.
 
light moths
darker moths
Moths set free
201
601
moths recaptured
34(16%)
206(34%)
Kettlewell's research (研究) was done in the early 1950s. Soon afterwards Britain introduced new laws to reduce smoke and factory pollution.
Can you imagine what would happen to the Peppered Moth as the air became cleaner again?
小題1:The Peppered Moth began to change its colour in industrial areas because         .
A．it itself liked to
B．it could be like the colour of its living-place
C．it had to keep the balance of nature
D．it was usually dark brown
小題2:From the results of Kettlewell's research, we can see that       .
A．many more of the light moths were killed or eaten
B．more than one-fifth of the light moths was not killed
C．three times as many dark moths were kept safe as light ones
D．more dark moths were killed in industrial areas
小題3:As the air became cleaner,        .
A．the number of the light moths became larger
B．the total number of the light moths remained unchanged
C．there were more of the darker moths and fewer of the light ones
D．the darker moths changed into the light ones suddenly
