Traveling is a very good activity. When you are fed up with your work and are allowed to take a holiday, you can go to the beautiful spots to enjoy the beauty of nature and the special character of other cities. You can breathe fresh air, visit some places of interest, meet different people and make friends with them. Then you will feel fully relaxed and you will have the energy to undertake the new tasks waiting for you.

    But sometimes, traveling is not an enjoyable thing. For example, when the bus or car you take has a bad accident, you may be trapped in it and waste your time. What's more, the weather can be changeable. If you are climbing a mountain, it may rain suddenly. You may be caught in the rain and may catch a cold. The worst thing is that you may have your money stolen and you may have an injury. All these are terrible things that can happen to a tourist.

    Therefore, before going on a trip, you must prepare yourself carefully. Firstly, you must have clear information about the weather. Secondly, you should choose a good companion so that you can help each other. Thirdly, you must be careful everywhere and try to avoid accidents. If you do these, you can enjoy your travels better and reduce unnecessary trouble.

    Far out in the lake was a large wooden platform(平台) on which stood an improbably high diving board- a kind of wooden Eiffel Tower. It was, I'm sure, the county's tallest wooden structure (结构) and no one had ever been known to jump from it. So it was quite a shock when our teacher, Mr. Milton, announced that he would dive off the high board that very afternoon.

    Word of his questionable plan was already spreading through town as Mr. Milton swam out to the platform. He was just a tiny, stick figure when he got there but even from such a distance the high board seemed almost to touch the clouds. Once at the top, he paced the enormously long board , then look some deep breaths and finally stood at the edge. He was going to do it.

    Several hundred people had gathered at the shore to watch. Mr. Milton stood for quite along time ;then he raised his arms, took one bounce(弹跳) and launched himself into ;perfect dive. He fell with perfect style for what seemed minutes. The crowd fell silent. But about three quarters of the way down he seemed to have second thoughts and began suddenly to panic(惊慌)，waving his arms and legs like someone having a bad dream. When he was perhaps thirty feet above the water, he gave up on waving and spread his arms and legs wide, obviously hoping that it would somehow slow his fall. It didn't. He hit the water at over six hundred miles an hour, making birds fly out of their trees three miles away. I don't think he entered the water at all. He just bounced off it, about fifteen feet back into the air. After that, he lay still on the surface , like an autumn leaf.

    He was brought to shore by two passing fishermen in a rowboat and placed on an old blanket where he spent the rest of the afternoon. Occasionally he accepted a little water, but otherwise was too shocked to speak.

    It was the best day of my life.

Blood Drive & Marrow（骨髓）Registration

    “These patients deserve a chance at a normal happy future and they rely on the kindness of the strangers to make that happen.”

— Daisy, Isabelle's Mother

    Isabelle is the daughter of Daisy and Saman Mirzaei. In January 2014 Isabelle, 12-year-old, was diagnosed with a genetic blood disorder, beta thalassemia. Isabelle's body is unable to produce healthy red blood cells. As a result, Isabelle has been receiving blood transfusions (输血) every 4-6 weeks since she was 13 years old. A lifetime of regular transfusions can lead to serious medical problems. Her only chance at a normal, healthy life is to have a marrow transplant. Isabelle is only a child, so doctors have started a search for an unrelated marrow donor through The Match Registry. The Mirzaei family asks that you consider helping patients like Isabelle by registering to be a marrow donor and give the gift of life, the gift of blood.

    In 2016, three viruses made news, and they present difficult problems for health officials in the New Year. One virus threatens babies in many parts of the world. Another has reappeared in an African nation. And a third is one of the deadliest viruses of modern times. The three viruses are Zika, polio and HIV. However, in 2016 scientists and researchers from all over the world worked to make progress against those viruses and to develop better ways to control them.

    The spread of the Zika virus caused public health officials in many nations to put in place strong measures to control its spread.

    Brazil, which hosted the 2016 Summer Olympic Games, was hit hard by the virus. Health officials warned pregnant women against traveling to the sporting event. Zika is usually a mild illness. It is so mild that most people who are infected do not know they have it. However, in the past two years in the Western Hemisphere, Zika has been linked to babies being born with extremely small heads. This condition is called microcephaly. The international medical community found that this link to birth defects makes Zika a very dangerous virus.

    Zika first appeared in Uganda more than 60 years ago. It is spread by mosquitos and by sex. The virus recently appeared in Brazil. Then cases appeared in other countries to the North. Cases were reported in the United States in the southern state of Florida. Health officials in Texas are also concerned the virus might be spreading there.

    Doctors can only advise women to be careful. They advise women not to travel to areas where the virus is spreading, to avoid mosquito bites or to delay pregnancy. Currently there is no vaccine against Zika. However, one could be available by 2018.

    When Joanne Morton and Lydia Shaw came across the Boston Public Market, which features only New England businesspersons, they knew they had to stop in. The women, visiting from southeastern Connecticut, always try to buy local. "We always try to support our local farmers and businessmen," says Ms. Shaw. "We're not into big companies," adds Ms. Morton.

    They aren't alone. A great number of Americans continue to be attracted by "local" food and to buy it, according to recent surveys from the International Food Information Council Foundation, the Pew Research Center, and British polling firm Ipsos. But what does it mean to shop local? For some, local is still a matter of geography. For others, it is about supporting their local economy (经济). And for still others, it is about knowing where their food comes from and how it is made, even if it is coffee shipped from a Costa Rican company. In 2008, Congress passed a bill that gave money to support local food. According to the Food, Conservation, and Energy Act, a product that can be considered local has to travel less than 400 miles.

    But Lydia Zepeda, a professor at the University of Wisconsin-Madison, has found the largest agreement about what is local is any product that comes from within an hour's drive. "But is that with or without traffic?" She asks. "What if it crosses state lines?" adds John Hayes, a food science professor at Pennsylvania State University. "A customer might like to buy local to help an old town," he says. "Or maybe it's just because local food tastes better." It is for Kaitlin Bohon. "I taste a difference," she says at the Boston Public Market. For Ms. Bohon, buying local is both about supporting New England business and knowing who grew and handled her food.

    Dujiangyan is the oldest man­made water system in the world, and a wonder in the development of Chinese science. Built over 2, 200 years ago in what is now Sichuan Province in Southwest China, this amazing engineering achievement is still used today to irrigate over 6, 000 square kilometers of farmland, take away floodwater and provide water for 50 cities in the province.

    In ancient times, the region in which Dujiangyan now stands suffered from regular floods caused by overflow from the Minjiang River. To help the victims of the flooding, Li Bing, the region's governor, together with his son, decided to find a solution. They studied the problem and discovered that the river most often overflowed when winter snow at the top of the nearby Mount Yulei began to melt as the weather warmed.

    The simplest fix was to build a dam, but this would have ruined the Minjiang River. So instead Li designed a series of channels built at different levels along Mount Yulei that would take away the floodwater while leaving the river flowing naturally. Better still, the extra water could be directed to the dry Chengdu Plain, making it suitable for farming.

    Cutting the channels through the hard rock of Mount Yulei was a remarkable accomplishment as it was done long before the invention of gunpowder and explosives. Li Bing found another solution. He used a combination of fire and water to heat and cool the rocks until they cracked and could be removed. After eight years of work, the 20­metre­wide canals had been carved through the mountain.

    Once the system was finished, no more floods occurred and the people were able to live peacefully and affluently. Today, Dujiangyan is admired by scientists from around the world because of one feature. Unlike modern dams where the water is blocked with a huge wall, Dujiangyan still lets water flow through the Minjiang River naturally, enabling ecosystems and fish populations to exist in harmony.
