长难句分析并仿写
Analyze the long sentences and make similar sentences
1. No one knows exactly how the earth began ,as it happened so long ago.
2. According to a widely accepted theory, the universe began with a Big Bang that threw matter in all directions.
3.What it was to become was uncertain until between 4.5 and 3.8 billion years ago, when the dust settled into a solid globe.
4.The earth became so violent that it was not clear whether the shape would last or not.
5.They were in time to produce carbon nitrogen water vapour and other gases ,which were to make the earth's atmosphere.
6. What is even more important is that the earth cooled down , water began to appear on its surface. 7. It was not immediately obvious that water was to be fundamental to the development of life. 8. What many scientists believe is that the continued presence of water allowed the earth to dissolve harmful gases and acids into oceans and seeds.
9.This produced a chain reaction, which made it possible for life to develop.
10.They multiplied and filled the oceans and seas with oxygen, which encouraged the shellfish and all sorts of fish.
11.Later when the plants grow into forests, reptiles appeared for the first time.
12. Why they suddenly disappeared still remains a mystery.
13.They are putting too much carbon dioxide into the atmosphere, which prevents heat from escaping from the earth into space.
14.As a result of this, many scientists believe the earth may become too hot to live on.
15.So why the life will continue on the earth for millions of years to come will depend on whether these problems can be solved.

用三个句子写出下面短文
一个礼拜天，我奶奶打电话告诉我那只猫第一次下了一只小猫。这使我很高兴。令我吃惊的是，当我想轻轻地摸一摸这只可爱的小猫的时候，大猫怒视着我并朝我猛烈地叫。我告诉他说，我不会伤害她的宝宝，而且每天我和奶奶会轮流照顾他们。
One day, my grandmother telephoned me that the cat gave birth to a baby cat for the first time, which made me glad. What puzzled me was that the cat was glaring at me and barking at me violently when I touched the baby cat gently. I told her that I wouldn’t do harm to her baby, and that we would take turns to look after them.
