问题 选择题

地球是我们生存的星球,她每天都发生着各种自然现象。图2为某月平均气压分布图,图中MN是晨昏线。回答8~10题。

8.根据图中的气压分布状况可知

A.极地高压控制亚欧大陆          B.亚洲低压控制亚欧大陆

C.北太平洋上低压势力强盛        D.夏威夷高压控制北太平洋

9.此时,下列现象可能出现的是

图2

A.北京是盛行偏北风的季节        B.印度洋北部洋流呈顺时针方向流动

C.地中海沿岸高温少雨            D.我国北极考察站处于极昼期

10.关于图中M点(位于赤道)的一些说法,可能出现的是

A.M点的地方时是6时

B.M地受气压梯度力和地转偏向力影响,盛行西北风

C.M地正午太阳高度不断减小

D.M地正值台风活跃季节

答案

8. C  9.A  10.A

从图中可以看出,亚欧大陆为高压, 太平洋为低压控制,此时是北半球冬季,北京盛行西北季风,北印度洋季风洋流呈逆时针方向运动,地中海沿岸多雨,北极附近为极夜。M点是晨昏线与赤道的交叉点上,应为6时或18时,而从季节看北半球为冬季,M点所在地段为晨线,故地方时为6点。M地地处赤道,没有地转偏向力。

     In 5 years,China plans to put its astronauts on the moon.But before that, a  small machine rover
(探月车) will be sent there.Recently, scientists  in S hanghai  showed  a  moon  rover to the public.
Scientists said they had spent four years making it.And they hoped the rover would be chosen to go
to the moon.
                                                      What is it like?
     The rover has  six  wheels (轮子).It is  meters  high and 200 kilogrammes in weight.It can take
videos and pictures of the moon.It can also get moon soil and study it.
     The rover can go as fast as 100 meters an hour.Experts say it can climb a 30-degree slope (斜坡).It is smart and can get around rocks.
      According to researchers,the rover may need to be improved.The moon's gravity (重力) is only
one--sixth that of  the  earth's.There are strong rays  (射线)  from  the  sun.The  temperature  also
changes greatly there.It can be --180~C at night and 150~C in the daytime.
     China wild explore the moon.First,a spaceship will be sent to go around the moon.There will be
no person in the spaceship.Then in 2012, a moon  rover  will be sent there.Finally,an astronaut will
land on the moon sometime after 2017.
     The China--made moon rover looks very similar to NASA'S Mars rover.But there are differences

1.If there is a box which is 60N on the earth,it is ________ N on the moon.
A.60          
B.10            
C.about 100    
D.about 600
2.Which of the following is right?
A.In 2012,an astronaut of China will land on the moon.
B.Mars rover runs faster than Moon rover.
C.Mar rover and Moon rover have the same power.
D.China has made a Moon rover.
