We all need a healthy environment, but we produce waste every day and it does harm to our environment. Though we are young,we can still do something to help. In fact, even the simplest everyday activities can make a real difference to the environment. Here are some ideas for you. Reduce Reduce means "use less",Don't waste things. This saves money and reduces pollution and waste going into the environment. Before we buy something new, think whether it is really necessary--or maybe the old one will be just as good! When we do buy things, choose local products if possible, and try not to buy too many things from abroad. Reuse Reuse means "use again". Use things for as long as possible. When we buy things,make sure that they last a long time. We should look after them so that they will last, and we should repair them if we can instead of throwing them away and buying new ones. Don't use a paper cup or a paper bag. It's better to use a china cup and a lunch box because you can use them again. Recycle Recycle means "change things into something else". Though it takes energy to change something into something else, it's better than throwing things away or burning them. Find out what can be recycled in your neighbourhood and take part in recycling programmes. We should also buy products made from recycled materials,such as recycled paper, to help save trees. So please remember these three words:reduce, reuse and recycle. Question: The passage may come from  _  . Options: A: a menu B: a dictionary C: a storybook D: a magazine

This is according to the World Health Organization. Few things can make people happy and full of energy like good music. Many people believe louder is better if you are listening to rock and roll. But if you really listen to the music loudly, even really good music, it can hurt your hearing badly. If a person takes a subway to go from one place to the other for half an hour in the morning and a half an hour in the evening, and every day has to _ on his audio device because there is so much of noise of the train and everything around, and is listening to for one hour every day, his hearing is going to be hurt seriously in a few years, in a couple of years time, for sure. There can be many kinds of unsafe levels of sound. It depends on how loud the sound is and how long you listen to it. Unsafe can mean noise levels of 85 decibels for eight hours a day or 100 decibels for just 15 minutes. There are simple ways to protect people from unsafe sound levels. Young people who wear earplugs during concerts can enjoy music at 90 decibels as much as they can at 110 decibels. But earplugs may not look very cool. The fact that earplugs may look un-cool may be true today, but if there is nothing wrong with your hearing in the future may be true and wearing earplugs may actually be cool. Another common suggestion is to turn down the volume on your personal audio devices. The World Health Organization also advises young people to limit their use of such devices to less than one hour a day. Besides, the World Health Organization reminds people to use technology, such as smart audio devices keep listening levels safe. Question: What music can make people happy and full of energy? Options: A: Sad music. B: Bad music C: Soft music D: Good music.

Read the article and select the best answer. Article: Our voice gives away a lot of information about ourselves. It can tell us our gender and age. And now, scientists say that it can also tell us our height. Scientists at Washington University, Indiana University and University of California found that listeners could accurately tell the height of speakers, just by their voices. And the key to this mystery is a sound known as the subglottal resonance . It _ with height and helps us build a mental picture of a person. "The best way to think about subglottal resonances is to imagine blowing into a glass bottle with water. The less water in the bottle, the lower sound," said John Morton, a scientist at Washington University. And it's the same for humans. The frequency of the subglottal resonance depends on the height. The taller we are, the deeper the resonance frequency is. In order to find out whether people could identify the resonance, scientists did experiments. A number of same-sex pairs of different heights were told to read the same sentence aloud. It was played back to listeners who had to choose which one of the pairs was taller. Then, other listeners had to rank the speakers from the shortest to the tallest. The listeners were able to identify the tall people 62.17% of time, much higher than a lucky guess. Why not try the experiment yourself? Find out if your tall friends have deeper voices. Question: Which of the following is TRUE? Options: A: Our voice is made up of the subglottal resonance. B: The people tested in the experiments were of different-sex pairs. C: A person's voice is greatly different even when reading the same sentence. D: Listeners' ability to identify taller speaker is much higher than a lucky guess.
