HOW LIFE BEGAN ON THE EARTH No one knows

（exact）how the earth began, as it happened so long ago. However, according （

）

a widely accepted theory, the universe began with a "Big Bang" （

）

threw matter （

）all directions. After that, atoms began to form and combine to create stars and other bodies.

For several billion years after the "Big Bang", the earth was still just a cloud of dust. （

）it was to become was uncertain until between 4.5 and 3.8 billion years ago when the dust settled into a solid globe. The earth became （

）violent that （

）was not clear whether the shape would last or not. It exploded loudly with fire and rock. They were in time to produce carbon, nitrogen, water vapour and other gases, （

）were to make the earth's atmosphere. （

）

is even more important is （

）

as the earth cooled down, water began to appear on （

）surface. Water had also appeared on other planets like Mars but, （

）

the earth, it had disappeared later. It was not

（immediate）obvious that water was to be fundamental to the

（develop）of life. （

）many scientists believe is that the continued

(present)of water allowed the earth

(dissolve) harmful gases and acids into the oceans and seas. This produced a chain reaction, which made (

) possible for life to develop. Many millions of years later, the first

(extreme)small plants began to appear (

) the surface of the water. They multiplied and filled the oceans and seas(

)oxygen, (

)encouraged the later development of early shellfish and all sorts of fish. Next, green plants began to grow on land. They were followed in time by land animals. Some were insects. Others,

(call)amphibians, were able to live on land as well as in the water. Later when the plants grew into forests, reptiles appeared (

)the first time. They produced young

(entire) by

( lay) eggs. After that, some huge

animals, called dinosaurs, developed. They

(lay)eggs too and existed on the earth for more than 140 million years. However,65 million years ago, the age of the dinosaurs ended. (

)they suddenly disappeared still remains a mystery. This

(disappear)made possible the rise of mammals on the earth. These animals were different (

) all life forms in the past, because they gave birth (

)young baby animals and produced milk to feed them. Finally about 2.6 million years ago some small clever animals, now with hands and feet, appeared and spread all over the earth. Thus they have, in

(they)turn, become the most important animals on the planet. But they are not looking after the earth very well. They are putting too much carbon dioxide into the atmosphere, (

) prevents heat (

)escaping from the earth into space. (

) a result of this, many scientists believe the earth may become too hot

(live) on. So (

)life will continue on the earth for millions of years to come will depend (

)whether this problem can

（solve）.
