In the wilderness, everyone has his own way to protect himself. Even plants have their own ways to fight off enemies.Over millions of

2、years, plants have developed their own defense system (防衛(wèi)系統(tǒng)). Chemicals are fantastically used by plants to survive (幸存). By making their leaves, flowers, roots and fruits poisonous (有毒的) to enemies, plants can fight back.One such plant is the Golden Wattle tree. The British scientist David Cameron

3、has found when an animal eats the trees leaves, the amount (數(shù)量) of poison increases in the other leaves. “Its like the injured leaves telephoning the others to fight together against the enemy,” he said. The tree also sends defense messages to neighboring plants by giving out a special smell. Golden

4、 Wattle trees in the nearby 45 meters will get the message and produce more poison within 10 minutes. Now, if an enemy eats too many of the trees leaves, he will die.Every kind of plant or tree is good at producing a special set of chemicals. Herbivores, like rabbits, can safely eat the leaves of on

5、e tree, but they may be poisoned by its neighbor.In this way, plants have not only developed their own defense system, but also shared it with others. This makes it impossible for a single animal to destroy even a small area of forest. 1From the first 2 paragraphs, we can learn that _. A. plants can

Locusts are super delicious food for birds,but it is not always an easy job for birds to catch them.It is neither because locusts are good jumpers or runners nor because they are smarte

21、r than their enemies. The reason is that the colors of locusts change with the colors of crops(莊稼). When crops are young,locusts look green. But when autumn comes, locusts change to the yellow and brown color as crops do. Brown bears,tigers and other animals move quietly through forests. They cant b

22、e seen easily by their enemies. This is because they have colors similar to the trees. For the same reason, polar bears that live on a land of snow and ice are white. Butterflies and bees living among the flowers are colorful like flowers. Soil insects are mostly dark-colored and they live under the

23、 soil(土壤） in a dark and wet environment. However, insects with colors different from plants can easily be found and eaten by others. So in order to survive,they have to hide themselves in the daytime and appear only at night. Have you ever noticed some even stranger acts? The ink fish in the sea can

24、 send out some very black ink when it faces danger. As the ink spreads over , its enemies will find themselves suddenly in a dark world. At the same time the ink fish immediately swims away.

For children, mobile phones are more than phone calls. They are fashionable. Most mobile phone users dont think about the healt

29、h problems caused(引起) by mobile phones. Some scientists say that mobile phones give off radiation(輻射) that might be bad for the users. One newest study shows that mobile phone radiation might raise(增加) a persons chance of getting some kinds of cancer(癌癥). Other scientists say mobile phones dont thre

30、aten peoples health. They say that they have not found any link(聯(lián)系) between phone use and cancer. Scientists say that people can protect (保護(hù)) themselves from mobile phone radiation.

They

39、 are easy to plant and easy to harvest(收獲). They have a good taste. When people think about carrots, they usually think they are a kind of long, thin, orange-colored vegetable. In fact, carrots are in many different sizes and shapes. And not all carrots are orange. Carrots should be grown in a field

40、 that does not have water for a long time. The earth also should not be too hard. To prepare your carrot garden, dig up the earth and turn it over(翻土). Weather, soil condition(土壤狀況), and time affect(影響) the taste of carrots. Warm days and cool nights are the best time to grow great delicious carrots

41、.The best way to decide if a carrot is ready to be harvested is by its color. Usually, the brighter the color is, the better the taste is.Most people do not know that carrots can be grown during the winter months. If the winter is not cold enough to freeze the ground, you can grow carrots the same w

42、ay as you do during the summer months.Carrots are prepared and eaten in many different ways. They are cut into thin pieces and cooked with other vegetables or meat. Or, they are washed, and eaten just as they come out of the ground. 26Carrots are easy to plant but hard to harvest.27Carrots should be

43、 grown in a field without water for a long time.28The best way to decide if a carrot is ready to be harvested is by its size.29Everyone knows that carrots can be grown during the winter months.30We can prepare and eat carrots in many different ways.Hi Brad,Its good to hear from you again. I find tha

44、t Im not good at writing compositions. Its hard for me to prepare the form of a composition and organize sentences. Could you tell me how to deal with this problem? I would really appreciate if you offer me some good methods. Best wishes, CindyHi Cindy,A composition is really a story and any story i

45、s told to an audience. There is a form for this and it is in three parts. First, tell them(the audience) what you are going to tell them. Then tell them, and finally tell them what you told them. Parts one and three are short and most of the information is in part two. It works like this.Lets say yo

46、u are asked to write a 200-word composition about your visit to the Great Wall. You would begin with an opening sentence or two saying something like “The Great Wall of China is a national landmark that is famous around the world. I visited it last summer and I want to tell you about it.” That uses

47、about 25 words to tell them what you are going to tell them.The second part would be about 150 words and would contain information about the Great Wall such as how long it is, when it was built, who built it and why, the fact that it is one of the seven wonders of the world and you would talk about

48、how you felt and what you thought when you visited this national treasure. This is telling them.Finally, you would use about another 25 words to say something like “That was my first visit to the Great Wall and it was a very emotional experience to actually touch something so old and famous. 每個(gè)中國(guó)人至少

49、參觀長(zhǎng)城一次.I plan to go back whenever I can.” Here, you are telling them what you told them in the story and wrapping it all up into a neat package. This formula(慣例)works for both compositions and speeches and I think you will find it helps to organize your thoughts. I hope its helpful.Best wishes, Brad

50、 Franklin31將文中處的畫(huà)線部分翻譯成漢語(yǔ)：.32(A) 試寫(xiě)出文中處畫(huà)線部分landmark的漢語(yǔ)意思：.(B)下面有四個(gè)在文中出現(xiàn)的單詞，請(qǐng)找出畫(huà)線部分發(fā)音哪個(gè)與眾不同? .A. work B. word C. information D. world33將文中處的漢語(yǔ)翻譯成英語(yǔ)： .34從文中找出適當(dāng)?shù)脑~組填空：How I wish to get a letter from you soon!How I wish to _ _ you soon!35用英語(yǔ)回答問(wèn)題：Whats the main idea of the passage? .When you look up into

51、 the sky at night, have you ever felt that your eyes are playing tricks on (捉弄) you? It seems that the stars are moving all the time.Actually, there is nothing wrong with your eyes. This twinkling effect is called scintillation (交光). Scintillation happens because of air movements in the earths atmos

52、phere (大氣). Light is “bent (彎曲的)” when it travels through different parts of the earths atmosphere. As the air in the earths atmosphere is moving all the time, the light from the stars looks as if it is moving too.The same thing also happens to things on the ground. On a very hot and shiny day, if y

53、ou look at the road, the image in the distance is not clear and things move slightly. You can also see the same effect if you drop a rock into water. The rock appears a little unclear under the moving water.This twinkling effect causes a lot of problems for astronomers (天文學(xué)家) since they cannot obser

54、ve the stars clearly. A telescope (望遠(yuǎn)鏡) was sent into space so that the air movements in the atmosphere could be avoided (避免). It took a long time to build the space telescope but finally in 1990, a huge space telescope called the Hubble Space Telescope was successfully sent into space. Since then,

55、astronomers have many important observations that have helped people understand space better.根據(jù)短文容，選擇最佳選項(xiàng)。 （10分）36What happens to the light from the stars we see when the air in the earths atmosphere is moving? A. It looks even brighter.B. It looks as if it is bent.C. It looks as if it is moving.D.

56、It looks like drops of rain.37Scintillation also happens on according to the passage. A. rainy days B. shiny daysC. cloudy days D. windy days38What can you see when you drop a rock into the water? A. The rock gets broken.B. The rock becomes unclear.C. The water becomes much polluted.D. The water doe

57、s not move anymore.39The underlined word “observe” means “”.A. watch B. listen C. draw D. explain40Why is scintillation a problem for astronomers? A. The stars never stay still.B. It makes the stars too dark to see.C. It makes astronomers feel too hot to work.D. Astronomers cannot observe the stars

58、clearly.Imagine the situation. You are driving along a desert or on a mountain. You have no idea where you are. You passed the last house two hours ago. Then your car breaks down. It is night and it is cold. You have no mobile phone. What do you do? Well, next time take a GPS with you. This invention may be able to help you. It is a device(裝置) which uses satellites (
