    Nowadays, Wechat is becoming more and more1in China. No matter where we are, we can send text or voice messages to our friends. We can also find a stranger to talk to by shaking the 2. Another funny function(作用) is that Wechat can help to search for people 3 live nearby with the app on. Many people like this function, 4 it can help them to find more people who they may know.

    In my opinion, Wechat is really 5 useful chatting tool. It can help people 6 with their friends more easily. 7, it is also bad for people, especially for students. As you see, some people use Wechat 8 too long. It is not healthy. So I have some advice on using it in a correct way. First, we should not use it when we are studying. We can't focus on our study if we use it. Second, we must be careful. We should neither show too much personal information 9 trust(相信)strangers so much

    We should learn how to use it properly(正确地). Remember, Wechat is not everything in your life. 10 depend too much on it.

    In 1845, a deadly disease struck the farms of Ireland, killing all the Lumper potato plants. In another place or time, the death of single crop species (物种) might not have been so important. But in Ireland, in 1845, people depended almost solely on the potato for food. The death of one species caused a terrible famine(饥荒). Now, some scientists are worried that such a famine could happen again, but on a much wider scale.

    Over the centuries, farmers have discovered thousands of different species of food crops. Each species has special qualities. Some can be grown in very hot or cold climates. Others are not affected by certain diseases. However, you won't find many of these species in your local supermarket. To feed the seven billion people on Earth, most farmers today are growing only species of plants and farming only species of animals that are easy to produce in large numbers.

    For example, in the Philippines, there were once thousands of varieties of rice: now fewer than 100 are grown there. In China, 90 percent of the wheat varieties grown just a century ago have disappeared. Scientists believe that over the past century, we have allowed more than half of the world's food varieties to disappear.

    One solution to this problem is to collect and store the seeds (种子) as many different plant varieties as we can before they disappear. The idea was first suggested by Russian scientist Nikolay Vavilov. In the 1920s and 1930s, he collected around 400,000 seeds from five contients. More recently, others are continuing the work he began.

    In the U.S. state of Iowa, Diane Ott Whealy wanted to protect historic plant varieties, like the seeds her great –grandfather brought to the U.S. from Germany more than a hundred years ago. She and her husband started a place called Heritage Farm, where people can store and trade seeds.

    More importantly, the people at Heritage Farm don't just store the seeds; they plant them. By doing this, they are reintroducing foods into the marketplace that haven't been grown for years. These food species are not just special in terms of appearance or taste. They also offer farmers food solutions for the future, from the past.

    The Silk Road is the name of different roads that long ago connected Europe, Africa and Asia. People reached these different places along these roads. Scientists believe people began to travel the Silk Road about 3, 000 years ago. By the time the Chinese silk trade became important in the world. The Silk Road covered almost 6, 500 kilometres. It spread from Rome to China, which is from the West to the Far East.

    Traders travelling along the Silk Road carried silk, of course. They also carried and traded spices（香料）, cloth, valuable stones and gold.

    There is a famous old story along the old road. It is said that Roman soldiers travelled through central Asia. They started to live somewhere near the ancient Chinese village of Liqian. Some of these Romans married local Chinese women and the story of blue-eyed villages of China was started.

    During its busiest period, the Silk Road allowed people from many different cultures and countries to meet each other and mix. The Silk Road allowed the sharing of valuable goods and new ideas. These included people and trading goods from the Mediterranean, Persian, Magyar,

    Armenian, Bactrian, Indian and Chinese areas. All these peoples travelled the Silk Road, and they shared goods, stories, languages, and cultures.

    In modern times, the old Silk Road routes are still used, but now they are crossed by trains instead of camels and horses. There is even a Silk Route Museum in Jiuquan in China. It has over 35, 000 objects from all along the Silk Road. In this way, China protects the history of many countries and peoples.

For centuries, children in North China wore tiger﹣head shoes. The shoes are so named because the toecap (鞋头) looks like the head of a big tiger. The traditional shoes are much like the animal itself.

It was until about 30 years ago, the shoes began to 1.However, Hu Shuqing, 51, from Henan Province, has spent many years2more than 10, 000 pairs of the shoes. She will give most of them to public museums, so that the next generation and the one after can see them. Chinese people began making tiger﹣head shoes in ancient times. The ancient people believed images (图像) of the animals, which were thought of as the king of beasts, could protect their children. That's one3why the shoes can still be seen now. On the other hand, the shoes look nice and can keep warm. In the north of China, it is very cold in winter. The shoes are good for keeping babies' feet warm.

Tiger﹣head shoes have many4.Some people change the images of tiger heads into frogs or peacocks, while more designs5spiders, snakes and scorpions (蝎子).

Hu was born6a family of paper cutters. Both her mother and grandmother could also make tiger﹣head shoes. "My daughter wore the shoes her grandma made when she grew up," she said.

But her hobby for collecting the shoes did not begin until 2000, when she found a 7pair at a Spring Festival market. "The images of tigers on the8were embroidered (刺绣) according to paper﹣cutting patterns," she said. From that day on, she has collected the shoes. She9collected in her home town, then in other provinces such as Hebei and Shandong.

Hu often goes collecting10September and December. "Kids wear tiger﹣head shoes in winter, " she said. "They are pretty and warm."
