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. Which of the following is TRUE? 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.

Sing the Language You're Learning How can you remember a song from your childhood to this day? Why do your teachers use songs to teach you English? It seems there is a scientific reason for this. Researchers are now studying the relationship between music and remembering a foreign language. They find that remembering words in a song is the best way to remember even the most difficult language. "Singing could be a new way of learning a foreign language. The brain likes to remember things when they are used in a _ and meaningful way", said Dr, Karen Ludke. The findings may help those who have difficulties learning foreign languages. On his blog, Dr. Ludke writes, "A listen-and-repeat singing method can support foreign language learning, and opens the door for future research in this area." Many language teachers know the value of using music and singing. Hua Zhuying, a teacher at a Chinese language school in Washington, D.C. depends heavily on songs in teaching Chinese. She says, "I use music all the time to teach children Chinese. For little kids usually we use the music. Not only does it work, but it is fun for kids." "Sometimes, I think if I were taught English that way, maybe I could speak much better English than now," Hua Zhuying adds. Our brain likes music, especially for remembering. So, if you're still struggling in learning a language, why not try singing it out ? From the passage, we know that Hua Zhuying  _  . A) is interested in writing English songs B) teaches children English by using music C) teaches Chinese in an American school D) is a researcher in a language school

Early to bed and early to rise makes a man healthy, wealthy and wise. This is an old English saying. It means that we should go to bed early at night and get up early in the morning. If we do, we shall be healthy. We shall also be rich and clever. Is this true? Perhaps it is. The body must have enough sleep. Children of your age need ten hours' sleep every night. If you do not go to bed early, you can not have enough sleep. Then you can not think properly and you can not do your work properly. You will not be wise and you may not become wealthy! Some people go to bed late at night and get up late in the morning. This is not good for them. We should sleep at night when it is dark. The dark helps us to sleep well. When the daylight comes, we should get up. This is the time for exercise. If the body is not used, it will become weak. Exercise keeps it strong. Exercise helps the blood to move around inside the body. This is very important. Blood takes nutrition   to all parts of our bodies. The brains in our heads also need blood. We think with our brains. If we keep our bodies healthy, and take exercise, we can think better! Our bodies also need air to breathe. Without air we will die. Get up early in the morning and we can have plenty of clean, fresh air. That will keep us healthy and happy. The old English saying"Early to bed and early to rise makes a man healthy, wealthy and wise."mainly shows   _  . A) what good habits are B) what bad habits are C) how to become healthy, rich and clever D) it's easy for people to get up and go to bed early
