Information is very important to people．In the past，books can “keep” information for us．If we forget something，we can  1  it up in books．Before inventing the printing press，books were written by  2  ．It was very slow．So，information traveled very  3  ．After the printing press，people could make many books quickly．More and more people could  4  books．Information began to travel much faster and much farther．

    Today，we can still find information in books，but we can also find information on the  5 very quickly．If we  6  our computers and   7   to the Internet，we can find lots of information that we want just in a few 8  ．For example，policeman call use information on the Internet to  9  bad persons and students can use information on the Internet to help with their homework．

Of course we can also get   10   from newspapers，on TVs or over the radios．But I think the fastest way to get information is to search the Internet．

Scientists think that there has    1    life on the earth for millions of years.    2   , we haven’t found life on other planets yet. Why?

The earth is a planet and it goes around the sun. There are other planets that also go around the sun. The sun and its planets    3    the solar system(太阳系). The solar system is a small part of our galaxy(银河系).

The stars we see at night are the suns in other solar systems. There are more than 200 billion stars in our galaxy, the Milky Way, and our sun is only one of them.

But scientists have    4    many other galaxies in the universe. They are a long way away and their light has    5    for many years to    6    us. It’s hard to    7    how large the universe is.

Scientists have    8    lots of spacecrafts to visit other planets in our solar system, and some spacecrafts have gone    9    the solar system. However, no one has discovered any life in space yet.

But why has no one from other planets sent us a message? Have they   10   to send information to us? Are we alone. Is there life out there in space? We don’t know.
