Life has gone mostly online for many people around the world. With more people going online during the COVID-19 pandemic, global Internet traffic has become a big problem. Between January and late March. many major cities experienced an increase in Internet traffic.
Video meetings, online classrooms and stay-at-home entertainment have become a daily routine. This increase in traffic is testing the Internet' s strength. In March. major phone networks in the UK experienced mass outages(断供). People were not able to take calls, receive texts or use mobile data.
In the US, major telecommunications companies like AT&T said traffic was up 21 percent month over month. Video streaming services like You Tube, Netflix and Facebook have cut their picture qualities and download speeds. This is being done to reduce network traffic jams.
China has seen an Internet traffic increase of around 50 percent compared to the end of 2019. The country's network speeds went down sharply in early February. However, they returned to normal soon afterwards and have been working well. This is due to China’s work in building network infrastructure(基础设施), especially 5G technology. By the end of February, 164,000 5G base stations had been built nationwide. This has given Chinese networks the power to handle increased traffic.
“If there were no such development in the Internet network field. people could hardly enjoy such a colorful life at home. Online working and teaching could never be realized so smoothly," said Wen Kun, an official with the Ministry of Industry and Information Technology.

Plenty of science fiction (sci-f) movies over the decades have shown us different versions of Mars. The truth about the Martian surface might be exciting because it's real. And with NASA' s Mars 2020 mission set to launch this summer, we're facing more discovery.
So far, thanks to a decade of research enabled by NASA's Curiosity rover, we've learned that lakes, rivers streams and likely oceans used to appear on Mars. While its water disappeared over three billion years ago, it tells us that Mars used to be habitable. This knowledge confuses us because so far, we've seen no clear evidence of life there, not even a virus. But if Mars was once habitable, wouldn't it have life?
NASA is now prepared to take the next step to answer this question with the launch of another rover, Perseverance. Every time a rover goes to Mars, it just stays there, with no way to fly back home. So we have never brought rock or soil samples back from Mars.
Perseverance rover will change this. Its primary and unique purpose is to collect samples that a future spacecraft can return to Earth. These samples will tell us more about the geologic history of Mars than anything we've learned, which is already a lot. Since 2012. the Curiosity rover has traveled more than a dozen miles, making observations along the way with its 10 instruments.
Thanks to data from the Curiosity rovers Sample Analysis at Mars instrument, we know that Mars does indeed have organic materials. That’s more complex than we expected to find on the surface of Mars. And that's exactly why we want to gather the most interesting samples and bring them back to Earth. We expect to find out much more about Mars once we get samples back from the Mars 2020 mission.
1.What is the purpose of Mars 2020 Mission?
A.To explore the Martian surface. B.To travel around the universe.
C.To show the power of NASA. D.To study the life on Mars.
2.What does the underlined word "habitable" in Paragraph 2 probably mean?
A.Enjoyable to visit. B.Suitable for living.
C.Ready for changes. D.Convenient to travel.
3.What was the problem with Mars exploration before Perseverance?
A.The rovers could not reach Mars.
B.Observations were hard to make.
C.Samples on Mars couldn't be brought back.
D.Study instruments got lost in the space station.
4.Which of the following can be the best title of the text?
A.New Mars rover to be launched B.Sei-fi movies on Mars to be made
C.Curiosity to bring back Mars samples D.NASA to send manned rover to Mars
