Going to outer space is a little like going camping. You have to carry with you all the food and equipment you need for your trip, so your food can’t be too heavy or hard to prepare. Plus, there are no refrigerators to keep food cold and fresh. Food with all the water dried out is lightweight and doesn’t spoil(变坏). So, many space foods are dried on Earth and stored in special packets.

On Earth, gravity is the force that keeps your feet on the ground and your sandwich on your plate. But there’s no gravity in space. To keep food from floating(漂浮) away, astronauts on the Space Shuttle attach the packets to a special tray(托盘). The tray can be fixed to a wall or to the astronaut’s lap. To prepare their food, astronauts use liquid forms of salt and pepper. The liquid sticks to the food better. Regular salt and pepper would float away, maybe up an astronaut’s nose.

Liquids float right out of cups and glasses, though. So astronauts drink everything from a small bag with a straw(吸管) that can be closed. Astronauts say that most space foods taste pretty good. Some, such as apples and pudding, are the same as the foods you eat on Earth.

Astronauts eat tortillas instead of bread because they make fewer crumbs(碎屑). Floating crumbs could get stuck in equipment or an astronaut’s eye.

Your body uses food in space the same way it does on Earth. Your body must deal with waste in space too. During takeoff and landing, astronauts can’t leave their seats to go to the bathroom. They wear diapers(尿布) under their spacesuits instead. The Space Shuttle has a bathroom the size of a small closet. The toilet has bars that keep astronauts from floating away. A strong flow of air is used instead of water to flush waste down the toilet.

1.Why do astronauts use liquid forms of salt and pepper to prepare food?

A. Liquid doesn’t spoil.

B. Liquid is convenient to use in space.

C.Liquid is lightweight.

D. Astronauts are in great need of water.

2.What do astronauts think of space foods?

A. Most of them taste pleasant.

B. They are mostly fruits.

C.Most of them are rather cold.

D. They contain too little meat.

3.We can infer from the passage that astronauts ___________.

A. drink from cups and glasses

B. always wear diapers in space

C. can move freely during landing

D. must pay attention to crumbs in space

4.What is the passage mainly about?

A. Astronaut’s hard life in space.

B. How astronauts go to the bathroom.

C. The various foods astronauts eat in space.

D. How astronauts eat and deal with waste in space.

Every year there are changes in climate in different parts of the world.Some of these changes are due to natural causes.However,some climate changes are caused by air pollution and these changes may increase.

If the pollution affects the level of carbon dioxide in the atmosphere,the results are likely to be serious.There is only a small part of carbon dioxide in the atmosphere.But it has an important function in keeping the balance between radiation from the sun entering the atmosphere and radiation leaving the Earth.Some of the radiation is absorbed by the Earth and some is radiated back into the atmosphere.The carbon dioxide in the atmosphere prevents some of the radiation from leaving the atmosphere.Thus the heat remains in the atmosphere and carbon dioxide helps to prevent the temperature of the Earth from falling.

If the proportion(比例)of carbon dioxide in the atmosphere is increased as a result of air pollution,the temperature of the atmosphere may rise.This might cause the ice in the North and South to melt.If this happened,the sea level could rise and parts of the Earth would be flooded.This is not quite likely but the possibility exists.

There is also a fairly strong possibility that the dust level in the atmosphere will rise as a result of industrial pollution.This dust pollution will reflect sunlight back onto space.If this happens,less sunlight will reach the Earth and the temperature will fall.

Another danger comes from the destruction(破坏)of the Earth’s vegetation(植物)such as the forest of Brazil,which is being cleared away for farmland and cities.Trees use carbon dioxide and their destruction may upset the balance of carbon dioxide in the atmosphere.

1.The main purpose of the passage is to tell us that .

A.the climate of the earth is always changing

B.air pollution has greatly affected the climate of the world

C.carbon dioxide has something to do with climate changes

D.the climate of the world is subjected to(使受到)dangers from air pollution

2.From this passage we learn that carbon dioxide .

A.helps to prevent the temperature of the Earth from rising

B.keeps much of the sun’s radiation from entering the atmosphere

C.plays an important part in keeping the balance of the temperature of the Earth

D.is one of natural causes of climate changes

3.Judging from this passage,if the level of carbon dioxide in the atmosphere went down,the temperature of the Earth would .

A.become higher B.either rise or fall

C.become lower D.neither rise nor fall

4.Which of the following is not the possible serious outcome if air pollution is related to climate changes?

A.Parts of the Earth would be flooded one day.

B.More sunlight would reach the Earth.

C.The temperature of the Earth might rise.

D.The Earth’s vegetation might be destroyed.

Nobody wants to reach the end of their life and experience regret. Instead, we desire to experience satisfaction with the life we’ve been given. 1. . To live a life without regret in the future, you should try to stay away from the following four common unhealthy habits.

2. It is good to have a destination to go to but it is the journey that matters in the end. Too often, we live our lives from destination to destination. But life is not lived merely in these destinations. In fact, it is far more often lived in the pathways between them. We should appreciate the joy in the journey rather than always hurry to the next destination.

Be defined by your negative circumstances. Each morning we are born again. What we do today is what matters most. This is an important truth and an important promise. Our lives should not be defined by the negative circumstances that happened in our past. They may have affected our lives, but they do not write the final chapter. 3.

Focus entirely on yourself. The size of our universe becomes smaller considerably when we place ourselves at the center. 4. On the contrary, those who see their life as an opportunity to bring joy to others quickly find it themselves.

5. Every excess (过量) adds burden to our lives. And yet we continue to pursue and accumulate more than we need—more houses, more cars, more clothes, and more dishes. Owning less means less cleaning, less burden, less anxiety, and less stress each day. It provides the space and opportunity to pursue the things in life that bring lasting satisfaction to our lives.

A. Blame everybody else.

B. Carry more than you need.

C. It is we ourselves who hold the pen.

D. Miss the joy of the journey for the destination.

E. Only a fool believes the wide road is necessarily the right road.

F. The fact is that too many people experience regret at the lives they chose to live.

G. And the people who are most focused on themselves are the least satisfied in life.
