问题 选择题

下图是北半球某地区近地面天气模式示意图。读图回答题。

小题1:该天气系统是

A.冷锋 

B.暖锋

C.气旋

D.反气旋小题2:此时,m、n两地的一般天气状况是

A.m、n两地都晴

B.m、n两地都有雨

C.m地有雨

D.n地有雨

答案

小题1:B

小题2:D

题目分析:

小题1:由信息可知,图中冷暖气团运动方向一致,故图示锋面为暖锋。

小题2:由信息提取可知图示锋面为暖锋,暖锋降水一般在锋前,而图中n地位于锋前,因此有雨。n地在锋面来临之前受冷气团控制,气温较低,随着暖锋影响,n地慢慢受暖气团控制而气温升高。

点评:解答本题需注意:(1)根据移动方向判断:冷气团势力强,冷空气就主动前进,这种锋属于冷锋,冷锋移动方向和冷气团前进方向相同。若暖气团势力强,则暖空气主动前进,冷气团被迫后退,这种锋属暖锋。暖锋移动方向和暖气团前进方向相同。(2)锋前和锋后是根据冷锋、暖锋的移动方向确定的:以锋线为界,冷锋前进方向暖气团一侧为锋前,冷气团一侧为锋后;暖锋前进方向冷气团一侧为锋前,暖气团一侧为锋后。(3)根据冷锋、暖锋的雨区范围判断:冷锋降水集中在锋后或锋线附近,雨区范围狭窄。暖锋降水集中在锋前,雨区范围较宽。

     A man came out of the airport. A lot of taxis were there. He asked the name of every taxi-driver. Then

he took the 3rd one. It cost 5 dollars from the airport to the hotel. "How much does it cost for the whole
