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

21、smarter than their enemies. The reason is that the colors of locusts change with the colors of crops(庄稼). 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. The

22、y cant be 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.

40、 in a field 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).

44、 I find that 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

45、any story is 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.

46、Lets say you 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.”

47、 That uses 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

48、talk about 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 famo

49、us. 每个中国人至少参观长城一次.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(惯例)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 Franklin31将文中处的画线部分翻译成汉语：
