The word “day” has two meanings. When we talk about the number of days in a year, we are using “day” to mean 24 hours. But when we talk about day and night, we are using “day” to mean the time between sunrise and sunset. Since the earth looks like a ball, the sun can shine on only half of it at a time. Always one half of the earth is having day and the other half night. A place is moved from day into night and from night into day over and over by the spinning(旋转) of the earth. At the equator(赤道) day and night are sometimes the same length. They are each twelve hours long. The sun rises at 6 in the morning and sets at 6 in the evening. For six months the North Pole is tilted(倾斜) toward the sun. In those months the Northern Hemisphere(半球) gets more hours of sunlight than the Southern Hemisphere. Days are longer than nights. South of the equator nights are longer than days. For the other six months the North Pole is tilted away from the sun. Then the Southern Hemisphere gets more sunlight. Days are longer than night. North of the equator nights are longer than days. Winter is the season of long nights. Summer is the season of long days.
【小题1】When the Western Hemisphere is having day, the Eastern Hemisphere is having ______.

On September 22, 2007, 108 Chinese cities took part in Car-Free Day, a global event held every year, for the first time.
China became the world’s second-largest auto market and third-largest car-maker in 2006. It has also become the second-largest greenhouse gas producer in the world, and is rapidly catching up with the United States. In this sense, China’s participation will greatly promote the Car-Free Day movement.
The number of cars on the road is going up rapidly in China. In Beijing, about 1,000 new cars are added to the streets on an average day.
Cars certainly offer people plenty of freedom to move around. But in many Chinese cities, appearance of too many cars has turned into a major problem. Getting stuck in traffic jams is an everyday experience for drivers.
Even worse is the environmental impact（影响）caused by cars. According to a national report, on a “smog day”, 79 percent of the air pollution is caused by cars.
The growing number of traffic accidents is another problem. Over 100,000 people die from traffic accidents every year in China, which is by far the highest number of road deaths in the world.
108 cities’ participation in Car-Free Day shows growing public concern about the traffic and environmental problems caused by cars.
On this day, all cars were banned from running in selected areas of the participating cities. People were encouraged to walk, cycle and use public transport. According to experts, the carbon monoxide in the atmosphere produced by cars was reduced by 3,000 tons on Car-Free Day.
With cleaner air and smoother traffic flow on the day, more cities will hopefully want to join the event next year. And more people might share the hope that Car-Free Day is not just on September 22, but a possibility 365 days of the year.
【小题1】From the passage, we can know that China ______.

Bicycles are very popular in China. In our country you can see bicycles almost everywhere. When you walk on the road, you will find a lot of people riding bicycles to schools, shops and anywhere else. Therefore, China is known as “the kingdom of bicycles”. In China, many families have one or two bicycles.
Compared with cars, bicycles have many advantages. First, they are much cheaper than cars. Most Chinese can’t afford cars, but they can afford bicycles. Second, bicycles are small enough to park anywhere, while cars need a larger piece of land to park. What’s more, with lower speed, bicycles are safer than cars.
However, bicycles also bring some problems. Some riders don’t obey the traffic rules and some riders don’t think about others safety. So they ride too fast. During the rush hour, too many bicycles may cause traffic accidents. We still have a long way to solve the problem.
【小题1】 Where can you see bicycles in China?

An earthquake happens when two plates rub (碰撞) together. The earth plates travel in different directions and at different speeds. If one plate is slowly forced underneath the other,  pressure builds up until the plates break apart. This process causes the ground to move. It is an earthquake. In other words, earth-quakes are the shaking of the earth’s surface caused by the earth’s rocky outer layer as a result of the energy stored within the earth. The strain within the rocks is suddenly released (释放).
The damage an earthquake causes depends on where it is and the time it is happening. If an unpopulated region is struck, there will be low loss of life or property. If it hits a large city, there may be many in-juries and much destruction. Many of the areas at risk are largely populated now. Major earthquakes hitting those areas today could produce terrible damage.
Actually, there are several million small earth-quakes every year.  Large earthquakes such as the 1964 Alaskan quake that measured 9.2 on the Richter scale, cause millions of dollars in damage. In the last 500 years, millions of people have been killed by earth-quakes around the world — including 240,000 in the 1976 Tangshan earthquake in China.
A 60-second or less earthquake can cause devastation that continues for years after the first tremor (小震). In 1972, a series of severe earthquakes struck Managua, Nicaragua. Fifteen years later, the city still looked the way it had a week after the earthquake hit, because the country did not have the necessary money to rebuild it.
The shaking of the earth is sometimes not the greatest disaster. It is in the ensuing fires and floods that often the greatest damage occurs. In the 1906 earthquake, it was the fires caused after it that did the majority of the damage. An earthquake can also destroy dams high above a city or valleys, causing floods to sweep down and sweep away everything in their path.
【小题1】Which of the following is the main idea of the first paragraph?

B
I believe that it is important to be brought up with a firm belief in the good. I was fortunate in this respect. My parents not only gave me a happy home, but they had me study half a dozen foreign languages and made it possible for me to travel in other countries. This made me more tolerant and helped me to bridge many difficulties in later life.
Soon after I got married, my husband and I left our native Czechoslovakia and went to live in Shanghai, China. Here was a really international city. People of all races and beliefs lived and worked together.
In Shanghai, in 1941, when I was only twenty years old, the doctors discovered that I had diabetes. It was a terrible shock, because diabetes is incurable. But it can be controlled by insulin (胰岛素). Although this drug was not manufactured in China, there were enough stocks of imported insulin available. This enabled me to continue a normal, happy life.
Then bombs fell on Pearl Harbor and the Japanese occupied Shanghai. The import of insulin was cut off. Before long, there was not enough for the diabetics. I was on a starvation diet to keep my insulin requirements as low as possible. Many diabetics had already died, and the situation became desperate. In spite of all this, I never stopped believing that with the help of my husband’s love and care, I would survive.
I continued to teach in Chinese schools. My faith and my husband’s never-ending efforts to get the manufacture of insulin started gave me courage. In his small laboratory the production of insulin was attempted. I served as the human guinea pig（实验品）on which it was tested. I’ll never forget the day when my husband gave me the first injection of the new insulin, which had worked on rabbits. It helped! Can you imagine our happiness and relief?
I received the greatest strength from the deep love and complete understanding between my husband and me. And next to that was the kindness and help of many, many friends of many nationalities. To me, the experience of living in Shanghai during the special times was unforgettable.
After the Second World War, my husband and I sailed to the Untied States, which is also known as a melt pot. Wherever we live, I believe, with faith and love, love between families and friends from different nationalities, we can make it our cherished home.
