1、The Hurricane1. A hurricane (飓风) is a tropical storm with winds that have reached a constant speed of 74 miles per hour. Hurricane winds blow in a large spiral(螺旋) around a relative calm center known as the "eye". The "eye" is generally 20 to 30 miles wide, ａｎｄ　the storm may extend outward 400 miles. As a hurricane nears land, it can bring heavy rains, high winds ａｎｄ　storm surges(风暴潮). The storm surges ａｎｄ　heavy rains can lead to flooding.2. Hurricanes are given a different label, depending on where they occur. If they begin over the North Atlantic Ocean, the Caribbean Sea, The Gulf of Mexico, ｏｒthe Northeast Pacific Ocean, they are called hurricanes. Similar storms that occur in the Northwest Pacific Ocean west of the Internaional Date Line are called typhoons near Australia ａｎｄ　in the Indian Ocean, they are referred to as tropical cyclones(龙卷风).3. When a hurricane hits land, it can do great damage through its fierce winds, heavy rains, inland(内陆的) flooding ａｎｄ　huge waves crashing on to the shore. During a hurricane, homes, businesses ａｎｄ　public buildings may be damaged ｏｒdestroyed, roads ａｎｄ　bridges can be washed away. A powerful hurricane can kill more people ａｎｄ　destroy more property than any other natural disaster. Fishermen are at special risk from hurricanes as they may be at sea when a hurricane arrives ａｎｄ　not be able to get to a safe harbｏｒif they do not receive adequate warning.4. If a hurricane is comming in your area, the most important thing is to stay calm ａｎｄ　find shelter immediately. Go to your safe room. If you do not have one, stay indoors during the hurricane ａｎｄ　go to a safer place near the center of your home. Cover yourself with a blanket ａｎｄ　be sure to keep away from windows ａｎｄ　glass doors, because if the glass breaks it’s really dangerous. Do not be fooled if there is lull(暂停), it could be the eye of the storm—winds will pick up again.Paragraph 4 ______【单选题】

3、HalloweenHalloween is an autumn holiday that Americans celebrate every year. It means "holy evening", ａｎｄ　it comes every October 31, the evening before All-Saints Day. It used to be thought the most wonderful night of the year. It was the night when witches ａｎｄ　evil spirits came back on earth. People kept up many strange old customs in an effort to keep these evil things away. Farmers used to light big fires in their fields, ａｎｄ　the farm workers ａｎｄ　their families would walk around the fields singing old songs. Sometimes they would stop to hear the local priest offer prayers to the good spirits, ａｎｄ　ask them to help keep the evil ones away. Great care was taken that none of the farm animals were left in the fields. They would all be locked up safely in their stables, ａｎｄ　over each of the stable doors a few rowan leaves would be hung. Witches ａｎｄ　evil spirits would not go anywhere near the rowan tree. In more recent times, Halloween has become a time fｏｒthe parties, when children dress up as witches ａｎｄ　play all kinds of special games. After the games there is often a big supper with plenty of pumpkin pie, cakes ａｎｄ　a lot of other delicious things to eat. But fｏｒthe most part the children enjoy the fun of dressing up ａｎｄ　playing their favorite game of "Trick ｏｒTreat". They run down each street knocking on the doors crying loudly "Trick ｏｒTreat! Money ｏｒeat!", ａｎｄ　most people have some sweets ｏｒmoney ready to give them. Those that do not can expect maybe to have a tyre flattened, ｏｒtheir windows covered in soap. ｏｒthe children may just knock on the doｏｒａｎｄ　run away. Some children think of other people on Halloween. They carry boxes fｏｒUNICEF (The United Nations International Children\'s Emergency Fund). They ask fｏｒmoney to help poｏｒchildren all around the world. Of course, every time they help UNICEF, they usually receive a treat fｏｒthemselves, too. Every autumn, when the vegetables are ready to eat, children pick large orange pumpkins. Then they cut faces in the pumpkins ａｎｄ　put lights inside. It looks like there is a person looking out of the pumpkin! These lights are called jack-o\'-lanterns, which means "Jack of the lantern". But in this modern age many of the pumpkins are being replaced with plastic electric ones that can be brought out each year. Which of the following statements about Halloween is FALSE, according to the text?【单选题】

A.Halloween has become a time fｏｒparties.

B.Children dress up as witches ａｎｄ　play special games.

C.People will enjoy a big supper with many delicious things to eat

D.Children will give sweets ｏｒmoney to their parents.

正确答案:D

答案解析:第4段讲了孩子们是怎样欢喜地过这个夜晚的，敲门索要糖果吃，如果不给他们吃的，可能你的轮胎就会被放气，窗户可能会被涂上肥皂。因此选项D的内容是错误的。

4、Seeing Red Means Danger AheadThe colｏｒred often means danger ａｎｄ　by paying attention, accidents can be prevented. In the future, the colｏｒred also may help prevent danger at construction sites. Thanks to new work by engineers, bridge supports ｏｒother kinds of materials could one day contain a colｏｒswitching material. It will turn red before a structure collapses ｏｒfalls apart. The secret behind the colｏｒswitching material is a particular type of molecule. A molecule is aｇｒｏｕｐof atoms held together by chemical bonds. Molecules come at all shapes ａｎｄ　sizes, ａｎｄ　make up everything. You can see, touch ｏｒfeel. How a molecule behaves depends on what kinds of atoms it contains, ａｎｄ　how they\'re held together. When a polymer (聚合物) containing a colｏｒswitching molecule called a mechanophore (机械响应性聚合物) which is about to break, it produce a color. When a polymer with mechanophore molecules becomes "injured" ｏｒweak, one of the mechanophore bonds breaks ａｎｄ　the material turns red. "It\'s a really simple detection method. "says Nancy Sottos, one of the scientists who worked on the project. Sottos ａｎｄ　her team tested the colｏｒswitching polymers in their lab. The test results proved encouraging. There is a way to get rid of the colｏｒlight when a bright light is shone on the mechanophore. The broken bond is fixed ａｎｄ　the red colｏｒdisappears. This "self-healing" may be a problem fｏｒengineers. They need to use the colｏｒchanger in big construction projects that will be outside in sunlight. ａｎｄ　sunlight will make the mechanophore\'s warming system useless. Sottos ａｎｄ　her fellow scientists still have ______ work to do before the colｏｒswitching molecules can be used outside the lab. 【单选题】

A.a part of

B.a type of

C.a lot of

D.a part of

正确答案:C

答案解析:意思应该是在变色分子可用于实践之前，Sottos和她的团队还需要做很多的努力。所以选a lot of合适。

5、A Star Is Born1 The VLT (Very Large Telescope) is the world\'s largest telescope ａｎｄ　is taking astronomers further back to the Big Bang than they ever thought possible. Located 2,600 meters up to the Chilean Andes, it has four huge mirrors, each about the size of a London bus. The VLT is so powerful it can spot a burning match 10, 000 kilometers away. 2 This astonishing power will allow astronomers to see events in space from the birth of stars to the collision of galaxies on the edge of the cosmos. The VLT is giving astronomers their best ever view of the cosmos. The power of the VLT to see the smallest detail at the furthest distances makes its designers amazed. 3 Take the case of Eta Carinae, one of the most explosive stars in the universe. This star produces ultraviolet laser rays (紫外线) ａｎｄ　it will destroy itself in a few million years\' time. It is five times brighter than the sun ａｎｄ　when it explodes it is going to be a sight worth waiting for. 4 But it is at distances of millions, even billions, of light years that the VLT really shows its power. The VLT can detect light that ｓｅｔout on its journey before the earth even existed. This gives astronomers their first ever detailed views of events that took place in the earliest days of the cosmos. 5 In other words, the VLT is a kind of a time machine. It takes astronomers back to a time when complete galaxies crashed into each other. The effects of these past collisions can now be seen by scientists, ａｎｄ　astronomers believe the telescope will reveal more about these exciting events in the years to come. One day, we might be able to say we have traveled back to the beginning of time, ａｎｄ　we will have a much clearer picture of how our planet was born. Paragraph 2____【单选题】

A.Events That Took place Before the Earth Existed

B.Power of the Telescope

C.Details of Eta Carinae

D.Invention of a Time Machine

E.Biggest Telescope

F.Ultraviolet Laser Rays

正确答案:B

答案解析:文章第2段主要介绍了LTV的功能有多大，故B为正确答案。
