The dinosaurs once lived happily on the earth. But 65 millio

The dinosaurs once lived happily on the earth. But 65 million years ago, they suddenly died out. What happened to them? Scientists thought that a change in temperature may be to blame. They have come up with lots of ideas to explain the end of the dinosaurs.
The most famous one is the minor planet(小行星) idea. Let’s go back to that day 65 million years ago to see what happened. Everything was OK before a large minor planet suddenly hit the earth. What a terrible hit! It caused big fires, storms, acid rain, and even earthquakes and volcano eruptions. The hit produced a lot of dust, which flew up into the air and blocked the sun for months. The earth became very cold without sunlight. The plants died first. Then the grass-eating animals died of hunger. Then the meat-eating animals could not find food either. They began to eat each other, but after a while they died out too. The dinosaurs, either plant-eaters or meat-eaters, did not live through the disaster(灾难).What a sad story! 翻译清楚 In April, a British scientist thought of a new idea about the death of the dinosaurs. He thinks that after the minor planet hit the earth, the temperature change left more dinosaur boys than girls! Without enough female dinosaurs to hatch(孵) the eggs, the dinosaur population became smaller and smaller.

解题过程：
　恐龙在地球上曾经幸福地生活。但在6500万年前,他们突然消失了。他们发生了什么?科学家们认为的温度变化可能是罪魁祸首。他们已经想出了大量的思想来解释的恐龙。
　　最有名的是次要的行星(小行星)的想法。让我们回到那一天六千五百万年前看发生了什么事。一切都好之前,一个大型小行星突然袭击地球。多么可怕的打击!它引起了很大的火灾、暴风雨、酸雨、甚至地震和火山爆发。到制作了大量的尘埃,飞到空中,阻碍了太阳了好几个月了。地球变得很冷没有阳光。这些植物死亡。然后食肉动物死于饥饿。然后食肉动物,就绝了粮。他们开始吃了对方,但是过了一段时间后就去世了。恐龙,要么食草動物或食荤者,没有渡过这场灾难(灾难).一个悲伤的故事!
　　在四月,一位英国科学家认为一个新的想法关于死亡的恐龙。他认为,在小行星撞后的大地,温度的变化,留下更多的恐龙的男孩比女孩!没有足够的女性恐龙孵蛋孵出,恐龙人口变得越来越小。
