As the Internet is developing fast，more and more new words and phrases have been created in Chinese. Here are some examples.

    One of the most popular words is Dianzan，which is often used when you quite agree with someone. Another example is Renxing.

    When you say somebody is Renxing，you mean that they will do whatever they like. The phrase Miaosha first came from online shopping，which means you can complete your shopping orders before others. But now it's widely used when you achieve your purpose in a very short time. If you describe somebody as a Tuhao，you mean that he is very rich.

    You can find lots of such new Chinese words. Keep learning and you'll know more about Chinese culture.

    Today people can use the phone to talk with others almost anywhere on the earth. But when you use the phone, you don't see the person you are talking with. That may change in the near future.

    Today some people are using a kind of telephone called the picture phone or vision phone. With it, two people who are talking can see each other.

    Picture phones can be useful when you have something to show the person you're calling.

    They may have other uses in the future. One day you may be able to ring up a library and ask to see a book. Then you'll be able to read the book right over your picture phone. Or you may be able to go shopping through your picture phone. If you see something in the newspaper that you think you want to buy, you'll go to your phone and call the shop. People at the shop will show you the thing you're interested in right over the phone. You'll be able to shop all over the town and never leave your room!

    You know how much your telephone has changed over the past 10 years? Your car will change even more than that in the next 10 years. One of the biggest changes is that cars will drive themselves.

    "We certainly have the technology for it now." says Andrew Poliak of automotive(机动车辆的)technology supplier QNX." We expect self-driving cars to be a mainstream thing between 2020 and 2025."

    The American company Google has been working on self-driving cars for years. These cars are already on the roads in the United States and are truly self-driving. They have to steering wheels(方向盘）or pedals(踏板). Last week, the police ordered one of Google's cars to stop for driving too slowly on a public road. The car was not breaking any law, so no one was punished.

    Another American company, Tesla, added an "Autopilot" feature to its cars last month. With the Autopilot turned on, the vehicle drives itself. The car will speed up, slow down, brake and drive by itself. You can take over driving any time by turning the steering wheel or touching a pedal. The car uses sensors to know when driveway changing is safe and whether it should speed up or slow down.

    Tesla Autopilot is made for cross-country driving. It keeps you in the driveway and helps you avoid hitting other cars. It does not work well on local roads, for it will not stop at a red light or stop sign.

    Reporter Carolyn Nicander Mohr tried the Autopilot feature of a Tesla earlier this month. She had a hard time trusting the car to do what it should do. She thought about disabling the Autopilot feature many times during her trip. She wanted to take control at every bend in the road and hit the brake when the car in front of her slowed down. Yet the car drove perfectly.

    Other companies are working on self-driving cars, too. Marcedes-Benz, Audi, BMW. Volvo and Toyota all have plans for such vehicles.

    April 22 is Earth Day. Everyone on Earth should care about and protect the earth!

    The earth has warmed by about 1°F (华氏度) over the past 100 years, but why and how? Well, scientists are not quite sure. Maybe the earth gets warmer and warmer on its own. But many scientists say that people are doing many things which makes the earth warmer. First, greenhouse effect (温室效应) is a very important reason for the change of the earth. People give out too much energy into the air every year. It makes the earth warmer. Climate (气候) change is another important reason. Sometimes it becomes too hot and sometimes too cold. Sometimes there is too much rain and sometimes too little. The change of the climate makes the earth warmer. In turn, the warmth of the earth changes the climate, too.

    When the earth becomes warmer, there may be more rain and a rise in sea level. It will affect the growth of plants, animals and people. On a Pacific island, 100 people have to move to higher ground because the sea is rising. These people can no longer live on the coast. Before that, two islands without people went underwater in 1999. Scientists say that the seas can rise by nearly one meter by 2100.

    People can affect the earth's air, land and water. As for us, we can do many things to protect the earth. For example, we can use fridges less. We can tell more people about protecting the earth.

    Earlier this year, China achieved a new milestone(里程碑) in space exploration(探索). On Jan 3, Chang'e 4 became the first space probe(探测器) in history to land on the far side of the moon, People's Daily reported.
    From Earth, we can only see one side of the moon. The other side has been a mystery. Scientists have long wondered what lies on this side of the moon.

    Chang'e 4 has sent back photos of the far side of the moon. It is also used to carry out experiments, such as growing seeds in a low-gravity(低重力) environment. The data(数据) collected from these experiments could be used to help us build a base on the moon in the future.

    The success of the Chang'e 4 mission(任务) is a main achievement for China's space program. It marks a new stage in China's deep space exploration, said Wu Yanhua, head of China National Space Administration.

    China launched(启动) its lunar(月球的) exploration program in 2004, naming it Chang'e. Chinese scientists set three goals —“orbiting(环绕运行), landing and sample(样本) returning”— referring to launching probes that could circle around the moon, touch down on its surface and bring lunar materials back to Earth.

    Chang'e 4 has realized the goal of landing. The third will be achieved during the Chang'e 5 mission, which is set to take place before the end of this year, China Daily reported.

    Following the success of the Chang'e missions, Chinese scientists are looking even farther into our solar system (太阳系). China's first Mars(火星) mission is expected to be carried out by 2020, Wu said.
