Long working hours can cause all kinds of health problems. Employers should encourage workers to take time off for lunch. This is because long lunch breaks can benefit both people and society. To take a lunch break is to slow down and gain some views. A break from work allows us to think cleverly and outside the box. It also puts our daily tasks into a wider context(环境).
What we eat at lunch is also important. A fast-food lunch is more harmful than not having lunch at all. And it’s not just about calories and unhealthy food. Recent studies show that fast food also has negative effects on how we think. However, if we sit down at a proper restaurant and chat leisurely with colleagues, we are more likely to slow down and talk about something that hardly can be achieved in a noisy and crowded fast food chain.

What would happen if you tried to blow a soap bubble in freezing weather? Would it freeze solid(固体) and fall to the ground? Would you have to hit it to break it? These questions happened to me on a cold winter day. It was too cold to play in the snow, but it was a perfect time to experiment with blowing frozen bubbles.
To blow frozen bubbles, I used dishwashing soap and a drop of glycerin(甘油)to make it even better. I chose a place out of the wind, and blew bubbles the same way I always do. I watched to see what would happen. Here’s what I learned.
If the temperature is low enough, the skin of the bubbles frosts over (结霜), becoming cloudy instead of clear. And what about those rainbow swirls(旋转)you see in soap bubbles? The rainbow colors stay even when the bubbles frost, but they don’t swirl anymore. The bubbles still stay in the air. They don’t fall to the ground any faster than they would on a warm summer day.
When these frozen bubbles break, they don’t turn into small water drops as summer bubbles do. They turn into flashing rainbow confetti(碎屑)and move slowly to the ground. Sometimes a frozen bubble will roll across the snow without breaking. If nothing disturbs the bubble, it may stay there for a long time. Sometimes I could catch a bubble and hold it until the heat of my hand made it pop.
I learned another thing about blowing frozen bubbles. It’s so interesting that I want to try it again next year.

In recent years, the proportion of girl students is growing fast. In 1998, about 39.7% of college students were girls. In 2000, it was 41.07% and in 2001, the number was 42.14%.
There are several reasons for this.
Firstly, there is little difference between boys and girls in their intelligence(智力). That’s to say, girls are as clever as boys. And boys have more interests than girls, so they may not always do well in their study.
Secondly, girls are more careful than boys. They work harder at school and they do better in all exams. Another reason is that with the development of society, people pay more and more attention to girls’ education.

A.boys are clever than girls |
B.boys can’t go to school |
C.girls have entered colleges |

A.Boys may not do well in their study as girls because they don’t like studying. |
B.Boys are much cleverer than girls because they’re interested in many things. |
C.Girls’ intelligence is the same as boys’. |
D.Girls study harder, but they couldn’t get higher marks than boys. |
I'm a helpless mother. My son Tom is 15 years old. I find that the older he grows, the less we talk. I feel very sad and I really need help.
My first problem is about his hobbies. He spends almost all his spare time on computer games. When he gets home, he always turns on the computer and closes the door. I'm getting worried about him, especially when his English teacher tells me he always gets low marks in the English exams.
Second, he likes new technology, but I don't have enough money and I can't afford all the things he wants.
Recently, I've found that he is always alone. I've never seen him talking to his friends on the phone or going out with anyone on weekends. That is the last problem I have.
What should I do to help him? Please give me some advice.

Many people love going on a trip by plane,but an airport is usually far from the city.You have to arrive there and wait for hours for the plane to take off and it is often late.You can’t open the window,you can’t choose the food.Planes are fast,but it takes hours to get out of the airport and into the city.
I like travelling by train.I think trains are safe.Train stations are usually in cities.When you are late for a train,you can catch another one.You can walk around in the train and open the windows.You can see many interesting things on your way.I know it takes a little sore time.
I also like cars.You can start your trip when you want to,and you don’t need to get to a station bus stop.You can carry many things with you,too,but sometimes there are many cars on the road.

The Earth is a planet and it goes around the Sun.Seven other planets also go around the Sun.None of them has an environment with air,so people and things cannot grow.The Sun and its planets are called the solar system.The solar system is a small part of our galaxy.
The stars we see at night are the suns in other solar systems.There are more than 200 billion stars in our galaxy,called the Milky Way,and our Sun is only one of them.
But scientists have discovered many other galaxies in the universe.They are a long way away and their light has travelled for many years to reach us.It is hard to understand how large the universe is.
Scientists have sent lots of spacecraft to look at other planets in our solar system,and some spacecraft have gong beyond 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 tried to send information to us?With so many stars in the universe,are we alone,or is there life out there in space?We don’t know...yet.

H. G. Wells could only imagine a travel to the moon. In 1969, human beings really left their footsteps on the moon. People today know that there are no underground cities on the moon. However, the question that the “moon people” asked is still an interesting one. A growing number of scientists are seriously thinking about it.
Underground systems are already in place. Many cities have underground car parks. In some cities, such as Tokyo, Seoul and Montreal, there are large underground shopping areas. The “Channel”, a tunnel connecting England and France, is now complete.
But what about underground cities? Japan’s Taisei Corporation is designing a network of underground systems, called “Alice Cities”. The designers imagine using surface space for public parks and using underground space for flats, offices, shopping, and so on. A solar dome (太阳能穹顶) would cover the whole city.
Supporters of underground development argue that building down rather than building up is a good way to use the earth’s space. The space, they say, can be used for farms, parks, gardens, and wilderness. H. G. Wells’ “moon people” would second it. Would you?
1. The explorers in H. G. Well’s story were surprised to find that the “moon people” .
A.knew so much about the earth |
B.understood their language |
C.lived in underground cities |
D.were advanced in technology |
A.Discovering the moon’s inner space |
B.Using the earth’s inner space |
C.Meeting the “moon people” again |
D.Traveling to outer space |
A.Offices, shopping areas, power stations. |
B.Tunnels, car parks, shopping areas. |
C.Gardens, car parks, power stations. |
D.Tunnels, gardens, offices. |
A.H. G. Wells once went to moon himself. |
B.Underground cities are more comfortable. |
C.The solar dome is a necessary part of underground cities. |
D.More underground systems will be in place in 2013. |
A.Alice Cities — cities of the future |
B.Space travel with H. G. Wells |
C.Enjoy living underground |

How would you like a trip to the moon? Men have already landed there. Someday, the moon might be a popular place to visit. What would a trip to the moon be like? Here are some facts.
There is no air or water on the moon. To stay alive, you would have to take your own oxygen(氧气) and water. It’s silent on the moon because there is no air. Sounds can’t be carried from place to place.
What will the surface(表面) of the moon look like? The moon has great round holes in it. There were more than 30,000 holes in all. The biggest one is 146 miles wide.
When you walk on the moon, you’ll feel light on your feet. That’s because you’ll weigh only about 20 pounds on the moon. You might forget what day it is on the moon because a moon day lasts for two weeks. But at least you won’t need a raincoat. It never rains on the moon. The weather on the moon never changes at all.
1. If you stay alive on the moon, you should take your own ________ according to the passage.
A.oxygen and water | B.food |
C.clothes | D.money |
