Space rubbish is also thought to be a great danger to spacemen. It’s reported that there were 9,000 man-made things flying in space. About 30% of these are satellites, 10% are spaceships, and the rest are space rubbish. An explosion(爆炸)in space in 1999 made a cloud of 300,000 fragments, each at least 4mm in size. A small piece of these even knocked a spaceship window and caused some damage（损坏）.

Scientists are watching and reporting any possible danger all the time. They are working to deal with space rubbish. Although space is really dangerous, it interests many people on the earth. In the near future, it may become possible for people to spend a few days in a space hotel. We may even choose to leave the earth and live in space in a few years. So we should do something to help improve the space environment.

In our daily lives many people always have negative thoughts. Being in a negative space is harmful to our life and study. If you keep them in mind, you will lose hope sooner or later. Let’s drive away some of the most common negative thoughts.

No one cares about me.

Sometimes you say that your family and friends don’t care about you. Maybe you are too negative and misunderstand the gestures of love they show you. They don’t have to be big gestures, but there are many countless little things they do for you. Maybe you just pay no attention to them and take them as granted. Perhaps you think they don’t care about you so you don’t make any effort in your relationships. Start showing people you care, so they can show you back in the same way. And if you don’t have good relationships wit the people you know, what’s stopping you from making new friends?

Why is she better off?

Comparing yourself to someone else is never positive. There’s always going to be someone who is younger, prettier, smarter, or richer than you. If you keep admiring what someone else has, then this may cause you to lose the balance in your mind, which will open a whole other negative can of worms. Remember, what they don’t have is your whole package. Be proud of what you have, because if you want to play the comparison game, remember that there are people who are also worse off than you are.

I’ll never reach my goal.

If you think you’re not going to be able to “get there”, think again. There are many people who are worse off and have overcome more difficulty than what you are facing.

Everything is within your reach as long as you work hard and have a positive attitude.

Almost all animals need to sleep to stay healthy. But sleeping can also be dangerous because other animals may hurt those who are sleeping. This leads to many different ways of sleeping that help them stay safe. Some of these ways may surprise you!

Almost all bats sleep upside down. They hang from a branch of a tree or the ceiling of a cave. Up high, bats are safe from most other animals. If they are in danger, they just fly away.

A dolphin sleeps with just half its brain at a time. It must stay awake to breathe and to watch for danger. Dolphin mothers and babies can go without sleep for as long as two months to stay safe.

Some ducks sleep with just half their brains, too. These ducks often sleep in a line. The ducks at both ends help to keep the group safe. They keep one eye open to watch for danger. The ducks in the middle sleep deeply with both eyes closed.

Seals breathe air, but that doesn’t stop some of them from sleeping underwater. They hold their breath and dive deep to sleep for up to twenty minutes at a time. Sleeping deep underwater helps these seals stay safe from animals that hunt them near the surface.

Horses often sleep standing up. Their legs lock in place so they don’t fall over. If a horse is lying down, it needs a long time to get up. A horse can run from danger more quickly if it is already standing.

A flamingo can sleep while standing on one leg. The standing leg locks so it stays straight. The other leg remains close to the flamingo’s body. Its head rests on its back. A flamingo lives (and sleeps) near many other birds to stay safe.

Some seabirds can sleep while they fly. These large birds spend most of their lives over the ocean. They are in danger on the water, but they are safe in the air. They fly for many hours without flapping（拍打）their wings. Sometimes they sleep while they are flying.

Would you like to sleep how they sleep?

1.The animals that sleep with half their brains are _______.

A. ducks and seals　　　　　 B. dolphins and ducks　　 C. bats and dolphins　　 D. flamingos and seabirds

2.Horses often stand up when they sleep because _______.

4.Which of the following can be the best title for the passage?

A. How animals sleep　　　 B. Sleep to stay healthy　　 C. Sleep as animals do　　 D. What sleeping animals are like

Cars are lots of fun, but they could also be dangerous. We have to be careful when we drive them or ride in them.

It's always a good idea to put on your seat belt when you're in a car. Why? Think about this example: You put an egg on a skateboard and give it a push. If the skateboard hits a stone, it will stop, but the egg won't. It will fly through the air, hit the ground and break.

Now, think what would happen if you tied the egg to the skateboard. When the skateboard hits a stone, the egg won't go flying; it will stay safely on the skateboard.

Volvo, a famous Swedish carmaker, was the first to use seat belts in 1849.

Air bags are also very important for car safety, because sometimes a seat belt isn't enough. If the car is going really fast and runs into something, seat belts could even hurt the people who wear them. Most new cars have air bags in front of and next to the seats. When a car hits something, its air bags will come out quickly in less than one second to keep the people inside safe.

1.The passage mainly tells us ________.

2.The writer gives the example of the egg to _.

3.Seat belts can make us safer because .

4.Air bags are important for cars because _.

5.Which of the following is TRUE according to this passage?
