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 bags for shop ping.

They think it is their duty to protect the environment.

Some people think only school children do not agree with their parents, however, it is not true. Communication is a problem for parents and children of all ages. If it’s hard for you to communicate with your parents, don’t worry about it. Here is some advice for you to bridge the generation gap(消除代沟)。
Don’t argue with your parents. Don’t get to your parents when you are angry. Your parents probably won’t consider your ideas if you are shouting at them. And you can’t express yourself well if you are angry. Go someplace to cool off. Make sure you understand why you are unhappy. Then think about what you want to say to your parents. If you don’t think you can speak to them at the moment, try writing a letter.
Try to reach a compromise (和解). Perhaps you and your parents disagree on something. You can keep your disagreement and try your best to accept each other. Michael’s mother didn’t agree with him about buying a motorcycle. They argued over it. But they finally came to a compromise. Michael bought the motorcycle, but only drove it on certain days.
Of course, your parents might refuse to compromise on something. In these situations, it is especially important to show love and respect to them. Showing respect will keep your relationship strong.
Talk about your values(看法). The values of your parents are probably different from those of your own. Tell your parents what you care about, and why. Understanding your values might help them see your purposes in life.
A good relationship with your parents can make you a better and happier person. It is worth having a try!The passage tells us ______ have a communication problem.

Many people go to school for an education. They learn languages, history, politics, geography, physics, chemistry and mathematics. Others go to school to learn a skill so that they can make a living.
School education is very important and useful. Yet, no one can learn everything from school. A teacher, no matter how much he knows, can not teach his students everything they want to know. The teacher’s job 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 than to memorize some facts or a formula（公式）. It is actually quite easy to learn a certain fact in history or a formula in math. But it is very difficult to use a formula in working out a math problem.
Great scientists before us didn’t get everything from school. Their teachers only showed them the way. Edison didn’t even finish primary school. But they were all so successful. They invented so many things for mankind. The reason for their success is that they knew how to study. They read books that were not taught at school. They would ask many questions as they read. They did thousands of experiments. They worked hard all their lives, wasting not a single moment. Above all, they knew how to use their brain. People go to school to _________.
| A．learn several subjects | B．make a living |

According to a new survey, students’ safety has become a big problem. Nearly 50% of students say they are worried about robbery (抢劫) on the way to and from school. Now in main big cities in China, some schools have taught students an unusual lesson: self-protection. Students like this lesson because there are no exams or boring classes. And they can learn how to save lives and know how to stop danger before it really happens.
Chen Haoyu, a teacher at Beijing No.25 Middle School, gives young students advice on how to deal with danger.
If you are robbed
Keep calm. If you cannot cry for help or run away, give the robber your money. Try to remember what the robber looks like and tell the police later.

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（长度）. They are each twelve hours long. The sun rises at 6 o’clock in the morning and sets at 6 o’clock 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 nights. North of the equator nights are longer than days. Winter is the season of long nights. Summer is the season of long days.When the Western Hemisphere is having day, the eastern Hemisphere is having ________________.
| A．both day and night | B．day | C．neither day nor night | D．night |
A place is moved from day into night and from night into day over and over by _______________ of the earth.
