听力原文: There have been many great inventions, things that change the way we live. The first great invention was one that is still very important today—the wheel. This made it easier to carry heavy things and to travel long distances.
For hundreds of years after that there were few inventions that had as much effect as the wheel. Then in the early 1800s the world started to change. There was little unknown land left in the world. People did not have to explore much any more. They began to work instead to make life better.
In the second half of the 19th century many great inventions were made. Among them were the camera, the electric light and the radio. These have all become a big part of our life today.
The middle part of the 20th century brought new ways to help get over diseases. They worked very well. They made people healthier and let them live longer lives. By the 1960s most people could expect to live to be at least 60.
By this time most people had a very good life. Of course new inventions continued to be made. But man now had a desire to explore again. The world was known to man, but the stars were not. Man began looking for ways to go into space. Russia made the first step. Then the United States took a step. Since then other countries, including China and Japan, have made their steps into space.
When did people stop exploring a lot?
A. In the second half of the 19th century.
B. In the 1960s.
C. In the first half of the 20th century.
D. In the early 1800s.
下列哪些说法是错误的?A.甲将乙价值2万元的戒指扔人海中,由于戒指本身没有被毁坏,甲的行为不构成下列哪些说法是错误的?
A. 甲将乙价值2万元的戒指扔人海中,由于戒指本身没有被毁坏,甲的行为不构成故意毁坏财物罪
B. 甲见乙迎面走来,担心自己的手提包被乙夺走,便紧抓手提包。乙见甲紧抓手提包,猜想包中有贵重物品,在与甲擦肩而过时,当面用力夺走甲的手提包。由于乙并非乘人不备而夺取财物,所以不构成抢夺罪
C. 甲将一张作废的IC卡插入银行的自动取款机试探,碰巧自动取款机显示能够取出现金,于是甲取出5000元。甲将IC卡冒充借记卡的欺骗行为在本案中起到了主要作用,因而构成诈骗罪
D. 甲系汽车检修厂职工,发现自己将要检修的一辆公交车为仇人乙驾驶,便在检修时破坏了刹车装置,然后交付使用。乙驾驶该车时,因刹车失灵,导致与其他车辆相撞,造成二入死亡,一人重伤。由于甲不是对正在使用中的交通工具实施破坏手段,所以不构成破坏交通工具罪
