If you go into the woods with your friends, stay with them. If you don’t, you may get lost. If you do get lost, this is what you should do.
Sit down and stay where you are. Don’t try to find your friends — let them find you. You can help them to find you by staying in one place. There is another way to help your friends or other people nearby to find you. Give them a signal by shouting or whistling three times. Stop. Then shout or whistle three times again. Any signal given three times is a call for help. You will be helped by others. Keep up the shouting or whistling, always three times together. When people hear you, they will know that you are not just making noise for fun. They will let you know they have heard your signal. They will give two shouts, two whistles or two gunshots. When a signal is given twice, it is an answer to a call for help.
If you don’t think that you will get help before night comes, try to make a little house and cover up the holes with branches with lots of leaves and grass.
What should you do if you get hungry or need to drink some water? You should have to leave your little branch house to look for a brook. Don’t just walk away. Pick off small branches and drop them as you walk so that you can find your way back. The most important thing to do when you are lost is — stay in one place.How do you let people believe that you are not just making noise for fun?
| A．Stop now and then. |
| B．Go on shouting or whistling. |

At age 61, identical twins Jeanne and Susan no longer look exactly alike. Susan smoked for many years and is an admitted sun worshipper, whose habits Jeanne does not share. A new study of twins suggests you can blame those coarse(粗糙的)wrinkles, brown or pink spots on too much time in the sun, smoking, and being overweight.
Because twins share genes, but may have different exposures to environmental factors， studying twins allows an “opportunity to control for genetic susceptibility(易受影响性),” Dr. Elma D. Baron, at Case Western Reserve School of Medicine in Cleveland, Ohio, and his colleagues explain in the latest issue of Archives of Dermatology.
Their analysis of environmental skin-damaging factors in 65 pairs of twins hints that skin aging is related more to environment and lifestyle than genetic factors.
But when it comes to skin cancer, the researchers say their findings support previous reports that both environment and genes affect skin cancer risk.
Baron’s team examined facial skin of 130 twins, 18 to 77 years old, who lived mostly in the northem Midwest and Eastern regions of the US, who were attending the Twins Days Festival in Ohio in August 2002. At this time, each of the twins also separately reported how their skin burned or tanned(晒黑)without sunscreen, their weight, and their history of skin cancer, smoking, and alcohol drinking. The study group consisted of 52 fraternal(异卵双生)and 10 identical twin pairs, plus 3 pairs who were unsure of their twin status.
From these data, the researchers noted strong ties, outside of twin status, between smoking, older age, and being overweight, and having facial skin with evidence of environmental damage. By contrast, sunscreen use and drinking alcohol appeared related to less skin damage.
Baron and his colleagues say the current findings, which highlight ties between facial aging and potentially avoidable environmental factors—such as smoking, being overweight, and unprotected overexposure to the sun’s damaging rays—may help motivate people to minimize these risky behaviors.Which of the following is true according to the passage?
| A．Jeanne and Susan share all the habits including smoking. |
| B．Skin aging is related more to environment and lifestyle than genetic factors. |
| C．Only identical twins can take part in the research. |
| D．Sunscreen use cannot help people have less skin damage. |
Why did Baron’s team do the research on twins?
| A．Twins are more likely to suffer from skin cancer. |
| B．It may guarantee the research is not influenced by genetic factors. |
| C．It gives others an opportunity to control twins’ genes. |
| D．It helps find twins are exposed to different environments. |
What can you infer from the last paragraph?
| A．This research makes people aware of dangerous lifestyles. |
| B．The environmental factors are unavoidable. |
| C．Being exposed to the sun is absolutely damaging. |
| D．There is little relationship between skin aging and environment. |
The passage is mainly concerned with.
| A．skin cancer and environment |
| B．identical twins research |
| C．aging skin and environmental factors |
| D．genes and lifestyles |

It is natural that children are curious (好奇的) about the world around them. For example, they want to know how their hearts beat. They want to know why the ocean water tastes salty.
As children grow up, they become curious about different kinds of things. When they are babies, they are interested in the parts of their bodies and in the smiles of their mothers. They become interested in the physical world around them: the plants, the animals, the sky. Later, they become interested in the things that people have made: wheels, bicycles, cars. And when they are adults, their curiosity continues. Sometimes this curiosity leads to a career (生涯、职业) in science.
Scientists spend their lives trying to find out about the world．Those who work with the earth sciences study the earth, the oceans, and the skies. Other scientists who study living things work with the biological sciences. A third group of scientists study the physical sciences, e. g. physics, chemistry .
These scientists have already discovered a lot about our world．For example, they tell us why your heart beats fast when you run. They say that when you are quiet, your heart normally beats sixty-five or seventy-five times a minute. Your heart is a pump (泵) that pumps blood to all parts of the body. The blood carries oxygen and nutrition. When you run, your muscles work very hard and use the nutrition that the blood carries to them. The muscles need oxygen, too . So your brain sends a signal to the heart. The signal means that the muscles need more nutrition and oxygen. Then the heart beats fast and sends blood quickly to the muscles. It may beat 90 to 140 times a minute.
Of course, scientists cannot answer all of our questions. If we ask, “Why does the ocean water taste salty” scientists will say that the salt comes from rocks. When a rock gets very hot or very cold, it cracks. Rain falls into cracks. The rain then carries the salt into the earth and into the rivers. The rivers carry the salt into the ocean. But then we ask , “What happens to the salt in the ocean? The ocean does not get saltier every year.” Scientists are not sure about the answer to this question.
We know a lot about our world, but there are still many answers that we do not have, and we are curious.According to the passage, which of the following statements is true?
| A．People are curious in the same way. |
B．People in different countries are interested in different things. |
C．Men and women are curious about different things. |
D．People of different ages are interested in different things |
Scientists who work with the biological sciences study____.
| A．the earth , the oceans and the sky | B．man-made things |
| C．plants and animals | D．ocean water |
When you run, your muscles need ____.
| A．more nutrition and oxygen | B．more signals | C．more salt | D．water |
A rock cracks _____.
| A．in wet regions | B．in dry regions |
| C．at very high or very low temperatures | D．when salty water falls in |
Tea drinking was common in China for nearly one thousand years before anyone in Europe had ever heard about tea．People in Britain were much slower in finding out what tea was like, mainly because tea was very expensive. It could not be bought in shops and even those people who could afford to have it sent from Holland did so only because it was a fashionable curiosity. Some of them were not sure how to use it. They thought it was a vegetable and tried cooking the leaves. Then they served them mixed with butter and salt. They soon discovered their mistake but many people used to spread the used tea leaves on bread and give them to their children as sandwiches.
Tea remained scarce and very expensive in England until the ships of the East India Company began to bring it direct from China early in the seventeenth century. During the next few years so much tea came into the country that the price fell and many people could afford to buy it.
At the same time people on the Continent were becoming more and more fond of tea．Until then tea had been drunk without milk in it, but one day a famous French lady named Madame de Sevigne decided to see what tea tasted like when milk was added．She found it so pleasant that she would never again drink it without milk. Because she was such a great lady her friends thought they must copy everything she did, so they also drank their tea with milk in it. Slowly this habit spread until it reached England and today only very few Britons drink tea without milk.
At first, tea was usually drunk after dinner in the evening No one ever thought of drinking tea in the afternoon until a duchess (公爵夫人) found that a cup of tea and a piece of cake at three or four o’clock stopped her getting “a sinking feeling” as she called it. She invited her friends to have this new meal with her and so, tea-time was born.Which of the following is true of the introduction of tea into Britain?
| A．The Britons got expensive tea from India. |

Tom Brennan was working in a Philadelphia office building when he noticed a black bag. The bag contained a book.
This chance discovery ended a 12-day search by the Library Company of Philadelphia for a historical treasure-a 120-page diary kept 190 years ago by Deborah Logan,” a woman who knew everybody in her day,” James Green ,the librarian told the magazine American Libraries.
Most of the diary is a record of big events in Philadelphia. It also includes a description of British soldiers burning Washington D.C. in the war of 1812. She describes President James Madison on horseback as "perfectly shaking with fear “during the troubled days. George Washington, she writes, mistook her for the wife of a French man and praised her excellent English.
The adventure of the lost book began on September 4 when Cory Luxmoore arrived from England to deliver the diary of his ancestor(祖先)to the Library Company, which he and his wife considered to be the best home for the diary.
Green told American Libraries he had the diary in his possession “ about five minutes” when Luxmoore took it back because he had promised to show it to one other person. On returning to his hotel after showing the precious book to Green, Luxmoore was shocked to realize that he had left it in the taxi.
Without any delay, Green began calling every taxi company in the city, with no luck, "I've felt sick since then," Luxmoore told reporters.According to Green, no one has yet learned how the diary came to the office building .
Tom Brennan received a reward(奖励)of 1,000, Philadelphia gained another treasure for its history , and Luxmoore told reporters, "It's wonderful news. I'm on high".This article mainly tells about the story of ___________.
