American teenagers hear it all the time from their parents, “Are you listening to me? Turn down that music or you’ll hurt your ears.” A new study has found the parents may be right.
The study has found that many young people in the United States do not hear as well as they used to. One out of five American teenagers have some hearing loss. That is a 30% increase in the past fifteen years. One out of twenty teens have a large hearing loss. That is a fifty percent increase.
The study has also found that boys are more likely to have hearing problems than girls. The age of the teens had no influence on their chances of a hearing loss. The researchers say they are not sure why some teenagers are losing their hearing. Not enough studies have been done and more are needed. Some say the reasons may be found in their diet or in their DNA. Others believe that listening to loud music on MP3 players with earphones is the main reason.
Researchers think that some teenagers do not realize that they are listening to music at very loud levels. Researchers suggest parents stand next to their children while they are wearing earphones. If the parents can hear the music, the sound is too loud. Teenagers should set the volume (音量) control on their music players to somewhere between one half and two thirds the highest level, never louder.
Even a small hearing loss can influence a child’s social development. Communication skills and grades in school can also be influenced. Doctor Eavey says, “What we are seeing is a big jump in the chances of hearing loss in a very short time.”

【推荐1】Prepare for Water Day Zero
Last year，Cape Town said it was facing Water Day Zero．That was the date when the city's taps would go dry．It was first expected to arrive in April，2018． Thanks to hard efforts and a rainy season，it has been put off（推迟）．
How did Cape Town get into a Water Day Zero situation？The city gets its water from six reservoirs（水库）．They usually fill up during the rainy season，from May through August．However，since 2015，the city had been suffering from its worst drought（旱灾）in a century．
Luckily，steps can be taken to avoid water crises（危机）．To start with，all of us can do something to save water and slow down climate change．
The world now has a chance to stop a series of Water Day Zero crises． If we don't act，many cities may soon face a time when there isn't a drop to drink．
| A．Cape Town is not alone． |
| B．The serious situation seems to be improved． |
| C．Water levels in the reservoirs became very low． |
| D．Cities can build more water﹣recycling factories． |
| E．However，the problem is very likely to appear again． |
| F．More and more countries are paying attention to the problem． |
【推荐2】At times we all get angry when we are driving. It might be because we are stuck in a traffic jam or stuck behind a very slow driver. It might be because we think another driver has done something very stupid. Whatever the reason, it seems that getting angry in a car is something which happens more and more often and there is now a special term for it---“road rage”.What do we know about road rage?
There are two kinds of road rage: aggressive (侵略的；侵犯的) driving and aggressive reactions to the way other people are driving. Aggressive driving can take different forms:
○Driving much faster than the speed limit (限制).
○Increasing your speed very quickly.
○Changing lanes very suddenly and stopping another car.
There are also different reactions to the way other people are driving. These include:
○Making rude signs at people.
○Shouting at people and hitting someone.
○Driving into another person’s car on purpose(故意)
Road rage is certainly not a joke. There have been accidents of road rage which have led to serious injuries(伤势) and even death.
Experts think that one reason for road rage is that films show a lot of examples of fast and aggressive driving which seems to be positive(积极的).
Experts also think that the punishments for dangerous driving are not serious enough. Experience shows that driving problems can be controlled, but it takes a long time. In the UK in the last 30 years, the police have been quite successful in reducing the number of people who drink and drive. They are now working to stop people using mobile phones when they are driving. Let’s hope they can have the same success with the road rage.

| D．The police will be able to do a lot to deal with road rage in the future. |
So, how old is “old”? The answer is one you’ve heard many times, from all kinds of people. “You are as old (or young) as you feel.” Your age simply tells you how many years you have lived. Your body tells you how well you’ve lived.
“Nobody grows old by living a number of years,” wrote a writer. “People grow old when they don’t have their ideals (理想).” People shouldn’t have the wrong ideas about aging. Sometimes, older minds can be as bright as young minds. Alice Brophy once said, “It makes me unhappy when people say, ‘You look young for your age.’ What does that mean? You know you can die old at 30 and live young at 80.”

【推荐1】Running is becoming popular these days. Many of us run for our health. Doctors say many of the health problems come from these bad habits: eating too much, drinking too much, smoking, and not taking enough exercise. Doctors tell us, “eat and drink less, don’t smoke, and exercise more.”
Running is a good form of exercise because it helps build a strong heart. It also helps most people lose weight. One 68-year-old woman runs three times a week. She runs to lose weight.
Running is good for health in other ways, too. Many runners say running keeps colds and other small health problems away. “Running is my doctor.” says one man.
Running can also help people to relax. So today men and women of all ages enjoy running.

【推荐2】We know the mosquitoes（蚊子）very well because they fly everywhere. They can be found almost all over the world, and there are more than 2,500 kinds of them.
No one likes the mosquito. But the mosquito may decide that she loves you. She? Yes, she. It’s true that male mosquito doesn’t bite and only the female（雌性）mosquito bites（咬）because she needs blood to lay（孵）eggs. She is always looking for things or people she wants to bite. If she likes what she finds, she bites. But if she doesn’t like your blood, she will turn to someone else for more delicious blood. Next time a mosquito bites you, just remember you are chosen. You’re different from the others! If the mosquito likes you, she lands on your body without letting you know. She bites you so quickly and quietly that you may not feel anything different. After she bites, you will have an itch（痒） on your body because she puts something from her mouth together with your blood. By the time the itching begins, she has flown away.
And then what happens? Well, after her delicious dinner, the mosquito feels tired. She just wants to find a place to have a good rest. There, on a leaf or a wall, she begins to lay eggs, hundreds of eggs.

【推荐3】The Beijing 2022 Winter Olympics was a great success. China has kept the promise to hold a green Olympics. It took more than six years to prepare for the Games. In this process, the designers put the idea of green Olympics into every part. They integrated green Olympics with the city and its surroundings (环境). Many green actions made it possible, like providing environmentally friendly smart beds, using a large number of new energy cars, supporting sporting places with 100% clean energy and reusing rain and snow water.
Take making ice as an example. China didn’t use R507, a common material to make ice, because it isn’t friendly enough to the environment. Through 18 months’ hard work, China independently developed the CO₂ direct cooling technology.
A net of tubes (管道) runs under the ice. High-pressure liquid (液态) CO₂ goes through them to create heat (热) exchange. The CO₂ evaporates (蒸发) under the ice surface. The evaporation takes in heat and turns water on the surface into ice. And the CO₂ goes into another circle. This technology helps to make ice better and faster. And above all, it is much greener because there’s no new CO₂ produced. Among all the 15 ice sporting places in the Winter Olympics, 7 used the CO₂ direct cooling technology to make ice. As a result, much less pollution was caused.
The Beijing 2022 Winter Olympics is the first to truly achieve carbon neutrality (碳中和), and it has set new standards in green technologies. Some newspapers say China has made great contributions to the world's environmental protection and green development.
