阅读
A
Some of you may play Ant Forest. It is a game on Ali pay. Users collect "energy" to make their "trees" grow.
When the "energy" reaches a certain level (程度), some organizations and companies will plant a real tree in a
desert area of China. And now it seems that the country's efforts as a whole to make a greener world have paid off.
According to a study by NASA, China and India are the main reasons for making the Earth greener over the
past twenty years. The study has found that since 2000 the Earth's green leaf area has increased by 5 percent, or
over 5 million square kilometers. The increased green leaf area is as large as that of the Amazon rainforest. It is
mainly the result of big trees-planting programs in China and intensive agriculture (集约型农业) in both countries,
according to NASA. China and India take up one third of the increased greening, but is only 9 percent of the
planet's land area covered in vegetation.
China played the most important role in the increase of the green land, adding 25 percent to this increase,
while India added 6.8 percent. Over the past years, China has made great efforts to green the land. In 1978, China
began a nation-wide forestation project–the Three North Shelterbelt Forest Program, also known as the" Great
Green Wall". The program has seen many trees planted in 13 provinces and autonomous regions such as Tibet and
Inner Mongolia in northern China to act as windbreak. By the end of 2017, the forest coverage rate among the
areas of the project had reached 13.57 percent, compared to 5.05 percent 40 years ago.
Because of China's success in dealing with desertification (沙漠化), the United Nations Environment
Program (UNEP) believes the country is a good example for others to follow. China is one of the most successful
countries in greening the desert and has lessons to share with the world.
（ ）1. What lesson can we learn from Paragraph 1?
A. Failure is the mother of success.
B. A small step can make a difference.
C. All work and no play makes Jack a dull boy.
（ ）2. The underlined phrase "paid off" means ________ in Chinese.
A. 获得回报 B. 支付费用 C. 还清账款
（ ）3. China and India ________.
A. get one third of the land area covered in vegetation on the earth
B. work together for the green leaf area in the Amazon rainforest
C. both play an important role in making the land greener
（ ）4. Which is right about the program "Great Green Wall"?
A . The Great Wall has become greener with the help of the program.
B. The program was started about 40 years ago to plant more trees in China.
C. Thanks to the program, many trees have been planted in Hunan Province.
（ ）5. The passage is mainly about ________.
A. China's important part in desertification
B. China's successful experience in working with India
C. China's efforts and achievements in greening the land

二、阅读理解
Your Internet experience will be influenced, when the net speed is too slow-it takes so long to open a web
page and the reality show you are watching stops every few minutes. That can be very unpleasant. But it could be
a thing of the past after 5G networks fully arrive.
The "G" stands for the "generation" of your mobile network. 1G let us talk to each other, 2G let us send
messages, 3G gave us mobile data (数据) and the Internet, and 4G made all of these things faster. About 100 times
faster than 4G networks, 5G will let people enjoy a faster Internet speed than ever before. This means that you
will be able to download (下载) an HD movie in seconds with a short delay (延迟). But 5G won't just bring faster
mobile Internet. People can use it for many other things as well.
With a 5G network, the short delay in information exchange will allow driverless cars to run more safely, as
they will be able to communicate in real time and avoid unexpected dangers. At the same time, 5G -enabled
wearable devices (设备) will keep doctors know what is happening to their patients and let them know in time if
there is something wrong. Besides, VR games will become more popular with 5G. The short delay of 5G will
make the games feel even more real.
According to BBC, though 5G will make our lives more convenient, it will not be perfect. For one thing, 5G
will not travel "far". On 4G networks, you can be 10 kilometers away from the nearest transmission base (传输基
站) and seldom lose signal (信号). But 5G will only cover about 300 meters, meaning that we will need more
transmitters so that we can get signals. And in order to use 5G, we will have to buy new products exactly made for
15
5G that are expensive now.
（ ）6. After 5G is widely used, ________.
A. opening a web page and the reality show can become a past thing
B. the Internet speed will be faster when we surf the Internet
C. we won't have the unpleasant feelings anymore
（ ）7. What can we infer from the Paragraph 2?
A. We cannot download an HD movie with 4G.
B. 3G makes it possible for us to go shopping online.
C. Faster mobile Internet is the only improvement for 5G.
（ ）8. What does the writer mean to do in Paragraph 3?
A. To give examples about the convenience brought by 5G.
B. To show different opinions from the possible 5G users.
C. To question the possibility of using 5G in daily life.
