user: 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 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. On Car-Free Day in 2007, 108 cities in China   _  . A) didn't allow people to drive B) didn't have air pollution C) called on people to drive less D) called on people to drive freely

Many people go to school for a good education. They learn languages, history, maths    and other lessons. School education is very important and useful. Yet no one can learn everything from school. No matter how much a teacher knows, he cannot teach his students everything they want to know. His work is to show his students how to learn. He teaches them how to read and how to think. So, much more is to be learned outside school by the students themselves. It is always more important to know how to study by oneself. It is quite easy to learn something in a language or a formula  in maths,but it is difficult to use a formula in finding the answer to a maths problem . Great inventors do not get everything from school but they can invent many things and change the world a lot. Though Thomas Edison invented many things he didn't have much school education. How do they do all these? Because they know how to study. A lot of things are not taught in the classroom. They get knowledge from books outside school. They work hard all their lives, and the most important thing is that they know how to use their head. What is the main idea of this passage? A) School education is important for a person. B) A student should learn how to remember a formula. C) A student can not learn everything from school. D) Inventors can invent things and change the world a lot.

Teary Joe was a boy with a special ability: he could make himself cry in less than a second. If he disliked something, or things became difficult, Teary Joe would not hesitate to put on a pitiful face and set great big tears running down his cheeks. In this way he managed to get practically everything he wanted, because no one could resist the pity inspired by his tearful little face. But one day, Teary Joe met Pipo.  Pipo was asking people in the street for some change, in return for him helping them in any way he could. Pipo was very poor; he had no home and no family, so he made a living however he could. Even so, Pipo always had the biggest smiles on his face. Joe took to Pipo, so he decided to help him out in making some money. He went over next to Pipo, took off his hat, put it face-up on the ground, and started crying with the most pitiful of expressions. Ina few minutes, Joe's hat was full of coins and sweets, but when Joe offered all this to Pipo, Pipo declined. "I prefer deserving what I receive," answered Pipo with his usual smile, "It's much more fun making an effort to get things. Maybe I haven't gotten everything I've wanted, but I've done a load of interesting things." Teary Joe didn't answer; he just walked sadly away. Joe had got everything he wanted, but he'd done practically nothing of interest the whole day. That evening, having returned home, Joe requested a delicious cake for his supper. When his mother said no, Joe tried to cry but, remembering Pipo and how joyful he was, he tried to get the cake in some other way. Joe spent the whole evening helping his mother to water the plants and organize the library books. In the end there was no cake. But that wasn't so bad, because Joe discovered it had been much more fun doing all those things that evening rather than just sitting crying to get a piece of cake that, in the end, wouldn't have been worth it. According to the passage, Teary Joe   _  . A) relied on others' sympathy   before B) was joyful in his life C) hated working hard D) was a naughty boy
