More and more people started to learn about 5G because it has many advantages. 5G will let people download and upload the data (上传数据) faster than before. People can use it for many other things as well. For example, 5G will help to make self-driving cars safer.

People could also use 5G to power the Internet of Things (IOT 物联网). It's a large online network that connects all things and people. Fast Internet speed will be the key to developing this technology.

5G is on the way. It will lead us to a new world. Are you ready?

There are countless myths（神话）to explain how the world came to have a moon to bring light to the night time. But now there is a plan for a man-made moon. It will give us far more light than the natural Moon.

China is preparing to put a man-made moon in the sky above Chengdu by 2020. It will reflect sunlight back on to the Earth. If it succeeds, three more such objects will be sent out in 2022, according to Wu Chunfeng, a space scientist. Wu said it would be similar to how we get moonlight, but he predicted that the man-made moon would have eight times the brightness of the real one. “This is because the object will be about 500 kilometers above the Earth. That will make it a lot closer to us than the Moon, which is over 380,000 kilometers away,” Wu added.

If the plan works, the man-made moon will save a lot of power. Scientists predict that Chengdu could save around 1.2 billion yuan in electricity every year if a new moon lit up 50 square kilometers of the city. And in 2022, four man-made moons can take turns to work as they will not always be in the best position（位置）relative to the Sun. Together, they can give light to an area of up to 6, 400 square kilometers on the Earth for 24hours. That means its brightness will be seen in most areas in China, reducing the need for streetlights.

1.Above which city is China preparing to put a man-made moon in the sky by 2020?

A.Beijing B.Shanghai C.Chengdu D.Wuhan

2.The underlined word “reflect” in Paragraph2 means“________”.

3.The man-made moon will be about ________above the Earth.

A.500 kilometers B.380,000 kilometers C.50 kilometers D.6,400 kilometers

4.What can we learn from the passage?

A.The man-made moon will be as bright as the natural one.

B.The man-made moon will work similarly to the natural one.

C.The man-made moon has already lit up the city of Chengdu.

D.The man-made moonlight will cover the whole china.

5.Which part of a newspaper may this passage be from?

Do you know 5G? It is the fifth generation（代）of mobile network technology. These new networks are coming.

China just issued commercial licenses（发放商用牌照）for 5G on June 6, 2019. This means that China's telecom companies will be able to offer 5G networks for mobile phone users.

Each mobile network generation is faster and more powerful than the one before it. 1G let us talk to each other. 2G let us send messages. 3G gave us data（数据）and the Internet. And 4G made all of these things faster. What's special about 5G?

Curiosity(好奇心) is part of human nature. Children are famous for wanting answers to thousands of questions. Books and TV shows often depend on curiosity. People keep reading or watching because they want to find out what happens. But curiosity also provides many advantages.

Learning is the easiest if you have a desire (愿望) for knowledge. Curiosity can create that desire when you have a question you want an answer to. Many of history’s greatest discoveries were made by curious people. Thanks to their curiosity, people now know far more about the world and have useful technology to help them.

Remember, everyone knows something that you don’t. Find out what that is, and ask about it. This lets you learn something and makes the other person happy by letting them show off their knowledge.

In the classroom or out of it, developing curiosity is sure to be valuable.
