They are easy to plant and easy to harvest(收获). They have a good taste. When people think about

37、 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 that does not have water for a long time. The earth also should not be too hard. To prepar

38、e your carrot garden, dig up the earth and turn it over(翻土). Weather, soil condition(土壤状况), and time affect(影响) the taste of carrots.

41、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 that Im not good at writing compositions. Its hard for me to prepare the form of a co

42、mposition 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,Cindy Hi Cindy, A composition is really a story and any story is told to an audience. There is a form for this and it is in three parts. First,

43、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 you are asked to write a 200-word composition about your visit to the Great Wall.

44、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 about 25 words to tell them what you are going to tell them. The second part wou

45、ld 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 how you felt and what you thought when you visited this national treasure. This

46、 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

47、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.7Best wishes,Brad Franklin 31将文中处的画线部分翻译成汉语： . 32(A) 试写出文中处画线部分 landmark 的汉语意思： .
