问题 选择题

我国喜马拉雅山地区有大量古老的海洋生物化石,证明:

A.这里曾经是一片火山

B.这里曾经是一片海洋

C.这里曾经是一片森林

D.这里曾经是一个很大的海生物动物园

答案

答案:B

题目分析:喜马拉雅山仍不停升高,且发现大量海洋生物化石的原因是地壳运动,使这一区域由原来的海洋变成高大的山脉。

点评:本题还可以考查地球上的海洋和陆地是时刻都在变化着的。“沧海桑田”举例:;②在我国东部海底发现古河流的遗迹(原因是海平面升降);③A欧洲荷兰的围海造田(原因是人类活动); 大陆漂移假说——海陆变迁最具代表的理论:(1)德国—魏格纳提出的;(2)依据 ①大陆轮廓线吻合;②物种相近;③古老地层吻合(3)理论:大约在2亿年前,地球上各大洲是连接的一块大陆,周围为海洋,然后慢慢分离。地壳的板块结构:(1)六大板块:名称、位置、范围、背图(2)大部分板块与大陆、大洲、大洋的范围一致。注意:亚欧大陆的阿拉伯半岛、印度半岛不在亚洲板块上而在印度洋板块上;亚欧大陆的东北角不在亚欧大陆而在美洲板块上,只有太平洋板块为唯一的大洋板块。板块内部比较稳定,板块与板块交界处比较活跃,世界上两大地震带:①太平洋沿岸地带;②地中海——喜马拉雅山一线;应用:①红海不断扩大:印度洋板块与非洲板块的张裂运动;②地中海在不断缩小:亚欧板块与非洲板块碰撞运动;③喜马拉雅山的形成、珠穆朗玛峰的不断升高:亚欧板块与印度洋板块碰撞运动;④日本、台湾多地震:亚欧板块与太平洋板块的碰撞运动;⑤太平洋不断缩小:太平洋板块的周边板块向其作碰撞挤压运动。

     I was always complaining about wind or rain.   1  it was nothing unusual for the arrival of wind or rain,
it caused inconvenience for me to go out, and sometimes it even created an awful atmosphere, so I   2  it
strongly.
     On a rainy day a meteorologist (气象学家) I met was very   3  at my great anger caused by rain that
made a little inconvenience for me.
     He asked, "Have you ever seen typhoon? Do you know what would happen to the world if there
were no typhoon?" I shook my head. I had no   4  of how overwhelming it was when it   5  everything
away in its way.
     "Well, let me tell you," the meteorologist said. "Without it the   6  of fresh water will be more serious,
for it is a great   7  of water supply on earth, Without it, there would be a greater imbalance in the
distribution of   8  . The equatorial area that receives the most sunshine on earth   9  entirely on typhoon
to disperse(驱散)heat. Without typhoon the tropics would be even   10  while the frigid zones much
colder. As a result the temperate zones would   11  from the world..."
     Ignorance made me   12  . I disliked wind only because it ruffled (吹乱) my hair. I hated rain merely
because I had to carry an umbrella. But I had no idea at all that typhoon-something much more violent,
something a thousand times more   13  than wind or rain-was a   14  to the existence of mankind. 
 15  no road on earth goes all the way on level ground, there's no person in the world who can do
whatever he pleases.   16  as it is for people to guard against typhoon, it is advisable for a man to stop 
 17 for a moment before he complains. "   18   disappeared all together? What would the world become
then?" The  19  will keep him calm and lead him closer to truth---he will be better  20  of the world he
lives in.
