问题 综合

(10分)读“我国部分地区某时地面天气形势图”,回答下列问题。

(1)此时A地处于   气压控制下,天气状况是   

(2)图中虚线(甲、乙、丙)附近易形成冷锋的是   ,丙系统过境后的天气是   

(3)图中①②③④四地中风速最大的是   ,其原因是    

(4)根据上面的天气形势图作出的天气预报正确的是        

A.东北地区天气晴朗

B.西北地区出现阴雨天气

C.内蒙古高原东部为阴雨天气

D.华北平原近日天气良好(5)目前图中a、b、c、d四地中受暖气团控制的为   ,可能出现降雨的为   

(6)b地吹   

答案

(10分,每空1分)

(1)高     晴朗

(2)乙     天气转晴(暖),气温上升,气压下降。

(3)②     等压线密集,水平气压梯度力大(气压差大)

(4)C 

(5)b、c    a、d

(6)西南风(或偏南风)

本题主要考查常见的天气系统对天气的影响等知识,同时考查等压线分布图的解读分析能力。正确解答该题的关键是认真分析图中等压线的分布特点及其依据区域轮廓进行准确的区域定位。(1)图中A处的气压由中心向四周降低,属于受高气压控制,是反气旋天气系统,中心气流下沉,因此天气晴朗为主。(2)图中甲虚线所在部位为高气压的高压脊,因水平气流辐散,不会形成锋面;虚线乙和丙所在部位为低压槽,因水平气流辐合会形成锋面,结合北半球的气旋是逆时针辐合,可判断乙处易形成冷锋锋面,丙处易形成暖锋锋面;暖锋过境后受暖气团控制,会出现晴朗天气,且气温升高,气压降低。(3)在等压线分布图中,往往等压线分布较为密集的地方,单位距离内的水平气压梯度力较大,因此风力也会较大。(4)从图中显示的区域轮廓看,此时我国的西北地区受高压控制,应是晴朗天气;内蒙古高原东部受低压控制,可能出现阴雨天气;东北地区会受暖锋活动的影响,天气变化明显;华北平原则会受冷锋活动的影响,天气变化剧烈。(5)从锋面活动的特点看,图中a、b、c、d四地中,a地位于冷锋的冷气团一侧,属于冷锋锋后,会出现降水;b地和c地受暖气团控制;d地位于暖锋的冷气团一侧,属于暖锋锋前,会出现降水。(6)b处的水平气压梯度力的方向主要指向北方,受地转偏向力的影响,风向向右偏,因此b地吹偏南风。

Hi Brad,

It’s good to hear from you again. I find that I’m not good at writing compositions. It’s hard for me to prepare the form of a composition and organize sentences. ①Could 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, 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.

Let’s 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 ②landmark 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 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 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 it’s helpful.

Best wishes,

Brad Franklin
