Compared to the other parts of the body, our ears don't ask for much. They don't need to be brushed once a day like your teeth. But they need some special care, especially if you like listening to music with earphones. Maybe your mum or dad has told you, "Turn that down before you go deaf!" Well, they are quite right. Loud noise might cause hearing loss for a short time or even forever. Think that earphones are a good way to escape from tour parents' eyes? Well. It may not be as good a way as you expect. American doctors have studied a group of 44,000 people who used earphones more than 15 hours per week. The doctors found that 37,000 of them were getting hearing problems. If you use earphones for too long a time, your ears might feel painful. You could also lose your hearing for the rest of your life. So don't wear your earphones too long. Use them less than one hour a day. Want sharp hearing? Don't forget to do the following: Try to stay away from places where there is too much noise, like a disco. If you have to go, wear earplugs. When swimming, remember to put earplugs into your ears to stop water from getting in. Never put anything sharp into your ears. If you think you have too much earwax, ask your mum or dad to help you clean it out. Keep these things in mind! Then you won't be saying "WHAT???" when you are older. If you want sharp hearing, you should _ . A) have your ears specially trained B) often wear earplugs and clean out the earwax C) take good care of your ears D) choose what you listen to carefully

Walls and wall building have played a very important role in Chinese culture. In ancient times, not only towns and villages, but also the houses and the temples within them were surrounded with walls. Also, the houses had no windows overlooking the street. Thus, walking in a city would give the feeling of wandering around a huge maze . The word "city" in Chinese also means "wall". The god of walls and mounts, whose duty was, and still is, to protect and be responsible for the welfare of the residents in these cities, villages, houses and temples. So a great and extremely hard task such as constructing a wall, which was supposed to run the length of the country, might not sound absurd . However, it is indeed a common mistake to think of the Great Wall as a single building structure, and it would also be a mistake to assume that it was built during a single dynasty. Actually, several dynasties somehow contributed to the construction of the Great Wall, the foundations of which had been laid many centuries ago. It was during the fourth and third centuries BC that warring states started building walls to protect their kingdoms, both against one another and against the northern nomads . The Great Wall played an important role in the growth of Chinese economy in history. Many settlements were established along the new border. Armies were instructed to reclaim wasteland and to plant crops there. Also, roads and canals were built. All of the work greatly helped increase the country's trade and cultural exchanges with many remote areas and also with the southern, central and western parts of Asia. Why did ancient Chinese cities seem like a maze? A) Because there were usually more walls than houses. B) Because the outside walls of houses had no windows. C) Because the word "city" means "wall". D) Because there were legends about the god of walls.

Ques: Even before they start school, many young girls worry that they are fat. But a new study suggests watching a movie starring astereotypically thin and beautiful princess may not increase children's anxieties. Nearly half of the 3 to 6 year old girls in a study by Professor Stacey Tantleff-Dunn and doctoral student Sharon Hayes said they worry about being fat. About one-third would change a physical feature, such as their weight or hair color. The number of girls worried about being fat at such a young age concerns Tantleff-Dunn because of the potential effects later in life. Studies have shown young girls worried about their body image are more likely to suffer from eating disorders when they are older. The encouraging news for parents is that taking their young daughters to see the new Disney film "The Princess and the Frog" isn't likely to influence how they see their bodies. "The media have a great effect on how young girls see their bodies. That's why it's important for parents to use movies such as 'The Princess and the Frog,' to start conversations with their children about weight, skin color and their views of beauty. They can explain that princesses' tiny waists are not realistic for girls and that children don't need Cinderella's golden hair or Snow White'sporcelain skin to look good," Tantleff-Dunn said. "We need to help our children challenge the images of beauty, particularly thinness, that they see and idolize, and encourage them to question how much appearance should be part of their self-worth," said Tantleff-Dunn. "We should help them build a positive self-image with an appreciation for many different types of body features." And as their children's most important role models, parents also should avoid criticizing their own bodies. The writer writes the passage mainly to _ A) explain the meaning of beauty B) introduce a new research finding C) stress the influence of media on girls D) teach girls how to become a princess

Worms,antis,and flowers live in soil.Fish,crabs,and seaweeds live in oceans.Birds,insects,and moss live in trees.soil,oceans,and trees are habitatsplaces where animals and plants live .Besides offering food and shelter, habitats allow for growth and reproduction. Humans, however,have destroyed many habitats.We change forests into parking lots. We turn grasslands into neighborhoods.We turn beach land into resorts.We turn 0ceans into chemical dumps.Some plants and animals adapt and survive.Others,however die.The changes are too much,too fast.Sometimes the death rate becomes greater than the birth rate.then the extinction occurs.An example of this happened on Florida's east coast,the habitat of the dusky seaside sparrow.This habitat changed suddenly as land was developed. And the sparrows were not able to adapt. More sparrows died than were born. In 1987 the dusky seaside sparrow became extinct.None exist in the world today. Fortunately,conservation efforts are underway.Many states have set aside land for nature preserves. Here,plants and animals live in their natural habitats.Some states have created man-made habitats .Artificial reefs,for example,have been put in ocean waters. The artificial reefs are habitats for hundreds of fish and other marine life.In 1970 the federal government passed a law to protect habitats.'Ibis~that the efforts of development must be studied.A highway,dam,or power plant may not be built if plants and animals,endangered.We were too late to save the dusky sparrow.Hopefully,however,these new efforts will save other plants and animals. The worst that can happen when habitats are destroyed is that plants and animals A) live in their natural habitats B) become extinct C) adapt and survive D) move to new habitats
