In the early 1990s the word "Internet" was strange to most people. But today, Internet has become a useful tool for people all over the world. Maybe Internet has been the greatest invention in the field of communication in the history of mankind. Communicating with others on the Internet is much faster. We can chat with a person who is sitting in the other part of the world. We can e-mail our friends and they can read the e-mails within a minute.
   Giving all kinds of information is probably the biggest advantage of the Internet. We can use search engines to find the information we need. Just type in a keyword or keywords and the search engine will give us a list of suitable websites to look at.

   We can enjoy a lot on the Internet by downloading games, visiting chat rooms or surfing(浏览)websites. There are some games for free. We can meet new and interesting people in the chat now. We can also listen to music and see films.
   Now, there is a lot of service on the Internet such as online banking, job finding and ticket buying. We can also do shopping and find nearly all kinds of goods. Sometimes we can find something that is quite good but very cheap.

    Techeng Island(特呈岛)lies in the southeast of Zhanjiang. The villagers there used to make a living by fishing. But now, most of them make much money by doing business. They believe that their island is a gift from nature and they give thanks to it every day. In 2003, President Hu Jintao came to visit the island and pointed out that the government of Zhanjiang should take the is land into a "civilized new ecotourism island"(文明生态旅游新海岛). Since then, the island has opened a new page in history.

    Today, the island has become a popular place for tourists. It takes you about 15 minutes to get there by boat from Maxie Pier(码头)near Haibin Park. But it is a just 8­minute boat ride from Zhanjiang Port Pier. In the resort(度假村), you can not only enjoy the fantastic sights but also have a lot of interesting things to do, like walking on the beach, visiting the museum and enjoying the delicious seafood. The best way to relax yourself is to enjoy the hot springs(温泉)there.

    Welcome to Techeng Island! It's a place to visit!

    Why is music so important to children? Here are some of my thoughts on the subject.

    Music has a positive（积极的） effect on young children's development!

    New research shows that music has a good influence on young children's cognitive（认知的） skills, such as spatial reasoning（空间推理） and memory. Research also shows that offering children an interesting environment can support children's healthy growth and development.

    Young children enjoy making music with others!

    Making music with others gives children a wonderful feeling of belonging to the group. Children might have difficulty joining in activities with others because they are shy, have limited language ability or special needs, but they can freely take part in a music activity.

    Music makes young children happy!

    Children seem to experience much pleasure and joy when listening to music, making music and dancing to music. Whether they are singing along to a CD, playing an instrument or dancing to music around the classroom, most children seem to thoroughly（彻底地） enjoy participating in a music activity. How wonderful it is to offer children the chance to do some activities about music!

    Tablets are really useful devices, but their big screens always make them as a burden to carry around without a bag. Wouldn't it be great if there were a phone with the powers of a tablet that could be folded up and fit into the hand?

Now something like a tablet-shaped but foldable phone is about to become available. In February, South Korean electronics company Samsung and China's Huawei both showed foldable phones, The Galaxy Fold and Huawei Mate X respectively. Mobile phone use has entered the "foldable future", The Verge noted.

    The technology could change our lives in unusual ways. These devices, due to their foldable screens, give us the larger screens we want. At the same time, they still fit easily into the pocket. As USA Today noted, they're "the combination of a small tablet and smartphone, all in a single device".

    The technology could change other devices too. For example, we could make TVs that stick to walls like posters, or fold up easily to hide away in drawers. In crowded modern cities, they will help us to make full use of available space.

    In a keynote speech, Samsung's senior vice president of mobile product marketing, Justin Denison, called the foldable screen "the foundation for the smartphone of tomorrow". "It's a piece of white paper for us to paint something beautiful on together," he said.

    So is there nothing to stand in the way of the foldable future?

According to technology news website Android Authority, the necessary displays* were difficult to produce. At present, these foldable devices cost too much. For example, the price of Huawei Mate X is 17,500 RMB. That's a price that few people will be able to afford.

    But if the foldable device isn't going to change the world overnight, there is no doubt that it is coming.

    Patrick Moorhead, an industry expert told The Verge, "Few are debating if foldable mobile displays are the future of smartphones; the only question is when and by whom."

    The world's largest radio telescope was finished on Sept. 25, 2017 in China.

    FAST is a five-hundred-meter telescope. It is also called Tian-yan ("The Eye of Heaven"), with a dish the sire of 30 football grounds, deep in the mountains of southwest China's Guizhou Province. The giant dish is built on a howl-like valley.

    The surrounding area has "radio silence" as there are no towns and cities within a 5-kilometer radius (半径范围) and only one county center within 25 kilometers.

    FAST is made up of 4, 450 panels (面板). The second largest radio telescope is in Russia. The bigger dish will be able to pick up weaker signals (信号).

    The radio telescope is like an ear, listening to tell meaningful radio messages from white noise in the universe. With the help of the telescope, we can receive weaker and more radio messages far away in space. It will help us to search for intelligent life outside of the Galaxy (银河系) and explore the origins (起源) of the universe. "Any of its discoveries will lead to a Nobel Prize," said Joseph Taylor, a Noble Prize winner.

    The FAST project began in 2011. And the telescope is expected to remain the global leader for the next 10 to 20 years.

    Now too much CO makes the Earth warmer and warmer, and brings bad effect to people. To save our Earth, a new lifestyle called low-carbon life becomes popular. Low carbon means low energy and no waste. It is necessary for everybody to learn to live a low-carbon life.

    To live a low-carbon life, we'd better save as much energy as we can. For example, turn off the lights and TV when you don't use them, use cold water to wash clothes or dishes: take a short shower and try to take a cold one when the weather gets warm: don't do the cooking with electricity.

    To live a low-carbon life, we should eat less meat. Being a vegetarian can help reduce (v)one and a half ton of carbon dioxide a year, but keeping animals for food produces even more carbon dioxide than all the cars do in the world.

    To live a low-carbon life, we should plant more trees. Trees are very important for us. They can not only produce oxygen for us to breathe and keep the air clean. But also take in the harmful gases from the air. To protect trees we should stop people from cuing down trees and plant as many trees as we can.

    If we can keep them a habit in our daily life, the earth will become a safer planet for us to live on.
