There is no doubt whether the Internet plays an important part in our everyday life. It can provide people with a life of highly quality. So it can also do harm to people, especially to teenagers. For an example, things such as violence and cheating often appear on the Internet, that can seriously pollute their hearts and souls (心灵). As result, children will gradually lose interest for their studies. Now it's time for the government to take some measures (措施) to deal of this problem. Some websites that breaks the rules should be punished and closed up. As students, we should also protect us from the bad influence of the Internet.

About a hundred yards along the path we came to a deep valley, on the far side of which the path led into some very thick bushes. Rather than push through these, I decided that if we walked along the bottom of this valley we could go up again and rejoin the path on the far side of the bushes.
As I climbed down into the valley a bird flew off a rock on which I had put my hand. On looking at the spot from which the bird had risen I saw two eggs. They were a kind that I did not have in my collection. So I placed them carefully in my bag, wrapping them in dry grass.
As we went further down the valley, the sides became steeper(陡峭)and not far from where I had entered it came to a drop of about twelve to fourteen feet. The water that rushed down all these small valleys in the rainy season had worn the rock as glass. As it was too deep to climb down, I handed my gun to one of the men and slid down it. My feet had hardly touched the sandy bottom when two men jumped down, one on each side of me. They quickly gave me the gun and asked me if I had heard the tiger. In fact, I had heard nothing, possibly because of the noise I made sliding down the rock. The men said they had heard a tiger growling(吼)somewhere nearby, but they did not know from which direction the noise had come.
