单选题Step Back in Time Do you know that we live a lot longer now than the people who were born before us? One hundred years ago the average woman lived to be 45. But now, she can live until at least 80. One of the main reasons for people living longer is that we know how to look after ourselves better. We know which foods are good for us and what we have to eat to make sure our bodies get all the healthy things they need. We know why we sometimes get ill and what to do to get better again. And we know how important it is to do lots of exercise to keep our hearts beating healthily. But in order that we don't slip back into bad habits, let's have a look at what life was like 100 years ago. Families had between 15 and 20 children, although many babies didn't live long. Children suffered from lots of diseases, especially rickets (佝偻病) and scurvy (坏血病), which are both caused by bad diets. This is because many families were very poor and not able to feed their children well. Really poor families who lived in crowded cities like London and Manchester often slept standing up, bending over a piece of string, because there was no room for them to lie down. People didn't have ridges until the 1920s. They kept fresh food cold by storing it on windowsills (窗台板), blocks of ice, or even burying it in the garden. Some children had to start work at the age of seven or eight to earn money for their parents. If you had lived 100 years ago, you might well be selling matchsticks (火柴杆) (a job done by many children) or working with your dad by now.

Not only do babies get to doze their days away, but they've also mastered the fine art of learning in their sleep. By the time babies are a year old they can recognize a lot of sounds and even simple words. Marie Cheour at the University of Turku in Finland suspected that they might progress this fast be cause they learn language while they sleep as well as when they are awake. To test the theory, Cheour and their colleagues studied 45 newborn babies in the first days of their lives. They exposed all the infants to an hour of Finnish vowel soundsone that sounds like "oo", another like "ee" and a third boundary vowel peculiar to Finnish and similar languages that sounds like something in between. EEG recording of the infants brains before and after the session showed that the newborns could not distinguish the sounds. Fifteen of the babies then went back with their mothers, while the rest were split into two sleep study groups. One group was exposed throughout their night-time sleeping hours to the same three vowels, while the others listened to the other, easier-to-distinguish vowel sounds. When tested in the morning, and again in the evening, the babies who'd heard the tricky boundary vowels all night showed brainwave activity indicating that they could now recognize this sound. They could identify the sound even when its pitch was changed, while none of the other babies could pick up the boundary vowel at all. Cheour doesn't know how babies accomplish this nighttime learning, but she suspects that the special ability might indicate that unlike adults, babies don't "turn off" their cerebral cortex while they sleep. The skill probably fades in the course of the first years of life, she adds-so forget the idea that you can pick up the tricky French vowels as an adult just by slipping a language tape under your pillow. But while it may not help grown-ups, Cheour is hoping to use the sleeping hours to give re medial help to babies who are genetically at risk of language disorders.

单选题 Thanksgiving Day The American Thanksgiving Day celebration goes back to 1621. In that year, a special dinner was prepared in Plymouth, Massachusetts. The people who had settled there had left England because they were forbidden to keep their religious belief. They came to the new land and faced difficulties in sailing across the ocean. The ship which carried them was called "the Mayflower". The North Atlantic was hard to travel. There were bad storms and huge waves. With the help of the Indians, they learned to live in the new land. These Puritans, as they were called, had much to be thankful for. They could enjoy religious freedom. They learned how to grow their crops in accordance with the climate and soil. Now when they selected the fourth Thursday of November for their Thanksgiving celebration, they invited their neighbors, the Indians, to join them in dinner. They also wanted to pray God for the new life. They recalled the group of 102 men, women and children who left England. They remembered those who did not live to see the shores of Massachusetts. They thought of the 65 day's journey which tested their strength.

单选题Look after Your Voice Often speakers at a meeting experience dry mouths and ask for a glass of water. You can solve the problem by activating the saliva in your mouth. First gently bite the edges of your tongue with your teeth. or press your entire tongue to the bottom of your mouth and hold it there until the saliva flows. Or you can imagine that you are slicing a big juicy lemon and sucking the juice. Before you begin your talk, be kind to your voice. Avoid milk or creamy drinks which coat your throat. Keep your throat wet by drinking a little sweetened warm tea or diluted fruit juice. If you sense that you are losing your voice, stop talking completely. Save your voice for your speech. You may feel foolish using paper to write notes, but the best thing you can do is to rest your voice. If you need to see a doctor, perhaps you can get some advice from a professional singer. In the meantime, do not even talk in a low voice. What about drinking alcohol to wet your throat? I advise you not to touch alcohol before speaking. The problem with alcohol is that one drink gives you a little confidence. The second drink gives you even more confidence. Finally you will feel all-powerful and you will feel you can do everything, but in fact your brain and your mouth do not work together properly. Save the alcohol until after you finish speaking. Perhaps you want to accept the advice, but you may wonder if you can ever change the habits of a life time. Of course you can. Goethe, who lived before indoor skating rinks or swimming pools, said," We learn to skate in the summer and swim in the winter. " Take this message to heart and give yourself time to develop your new habits. If you are willing to change, you will soon be able to say that you will never forget these techniques because they became a part of your body.
