However, I think people are happier and freer when watching movies at home.Watching movies at home is more comfortable. To watch movies in a cinema, you have to buy a ticket before you go there for a better seat. However, there is no need for people at home to worry about the ticket. They can enjoy movies at any time they like and with the most comfortable seat. What's more, people watching movies at home wouldn't have to face any traffic problems.It is free to watch movies at home. In the cinema, we can't go outside and do something else because the movie won't wait for us. Sometimes, if we miss part of the movie, we can't follow the story. At home,we can pause at any time and go back to watch the part.All in all, a cinema is a good place to watch movies, but it isn't the best place to enjoy the movies.

(10分) Do you still get free plastic bags from the supermarkets? Things have changed.China has banned(禁止)free plastic bags in shops and supermarkets,and people have to pay for using plastic bags. The rule started on June 1st. It came because our country tried to make less litter. Making super-thin plastic bags has also been banned.The Chinese once used about 3,000,000,000 plastic shopping bags a day,and they have caused pollution of the environment. The bags have become a main cause of plastic pollution because they are easy to break and people throw them away here and there. So the Chinese people are encouraged to bring their own bagsfor shop ping.What kind of shopping bag is the best to bring? Some students in Chongqing have a good idea. They make their own shopping bags. They use old clothes to make cloth bags,and send them to their parents as presents. They also ask their parents and friends to use cloth bags instead of plastic ones. They think it is their duty to protect the environment.根据短文内容,选择最佳答案。

(10分)阅读理解We all dream about things that we would like to do and things we hope to achieve in the future. But are everybody's dreams the same? Here are some of the findings of a survey about hopes and dreams,and thousands of students across China took part in it.What are the hopes of teenagers?We received several different answers to the question:What would you like to do after finishing your education? It seems some students would like to start work as soon as possible, so that they can help provide better lives for their parents. Other students hope to continue studying after finishing school and to go to university. Although money is important, many teenagers said they want to do jobs they enjoy. According to the survey, the most popular choice of job is computer programming.What are the dreams of teenagers?Teenagers have all kinds of dreams. Some are more realistic(现实的) than others. For example, many students said they would like to be volunteers if Beijing could hold the World Cup, maybe working as translators or tour guides. And quite a few said they dream of going to the moon one day. According to the survey, less realistic dreams are also common, but many students reported that they were willing to work hard to achieve their dreams. Quite a few dream of becoming famous, perhaps famous sports people or singers. Some said they'd like to go on exciting trips; one student said she'd love to sail across the Pacific Ocean. And then there are dreams that are impossible; three students said they'd like to be able to fly!ConclusionIt was clear from the survey that teenagers have similar hopes. It seems that most students hope to have a good education and find a good job. Besides,students dream of very different things:good things, and even crazy things. It is very important to dream, so hold on your dreams; one day they may just come true.(1)Some students would like to start work to ______ as soon as possible.A . find jobs they enjoyB . achieve their dreamsC . to help look after their familiesD . make money to go to university(2)What is important to students about their work they do?A . If it is a good job.B . If they can enjoy the work.C . If it can help him become famous.D . If they can make more money.(3)How many realistic dreams are mentioned in the passage?A . Three.B . Four.C . Five.D . Six.(4)What example is given of an impossible dream?A . To be able to fly.B . To go to the moon.C . To sail across the Pacific Ocean.D . To become famous people.(5)What's the writer's opinion of dreams?A . Give up impossible dreams.B . Common dreams are not so good.C . Teenagers should have realistic dreams.D . Dreams are important and try to make them come true.12. (4分)请阅读下表,找出小题中正确的一个选项。
