As of June, China had about 285 million Internet users living in rural areas,     1     (account) for over 30 percent of the country’s total, according to a recent report on China’s Internet development. The number of rural Internet users in China     2     (grow) by over 30 million in the last few months.

The report said the Internet is playing a     3     (great) role than ever in the country’s poverty(贫困) reduction efforts, with the public’s participation in and recognition of relevant campaigns on the rise. It said as of June,online promotions of     4     (agriculture) products from remote areas had reached more than half of the Chinese Internet users,     5     that more than one third of netizens had bought such products via online platforms.

Meanwhile, the report shows that e-commerce livestreaming(直播) grew     6     (increasing) active in the first half of the year. As of June, the number of e-commerce livestreaming users in China had hit 309 million, up 16.7 percent from March. China saw over 10 million livestreaming marketing activities in the first half of this year, attracting over 50 billion     7     (view), the report noted.

The report said the Internet can contribute significantly     8     China’s anti-poverty goal by providing jobs, social security and medical service information for     9     poor and allowing children in poverty-stricken areas     10     (access) better education.

It’s not unusual for a person to help someone else out without getting anything in return. But this    1    (behave) hadn’t been seen in birds. That’s why scientists created an experiment    2     (design) to test whether African grey parrots were willing to help each other out.

The first step was to teach the parrots to trade tokens (代币) for food,     3    were small metal rings. When the parrots gave these tokens back to the researchers, every time each parrot was given     4     walnut they enjoyed. Once they knew how    5    (exchange) tokens for walnuts, two parrots were put in clear plastic cages next to each other,     6    an opening between the two cages.

There was a feeding window in both cages that allowed the scientists to give walnuts to the parrots. Then the feeding window     7    (close) for one of the parrots, who had been given ten tokens. The results showed this parrot that couldn’t trade for walnuts would pass a token     8     (eager), beak-to-beak, to the bird in the next cage, who could then trade it for a walnut.

“Many of the parrots tested passed all 10 tokens, always     9    (watch) how their partners got the food and getting nothing for     10    (they). How unselfish they were!” said Desiree Brucks, the lead scientist.

With the globalization, our traditional culture is being lost,     1     can be easily found in our life. For example, our traditional culture has lost     2     (it) important role in education. More and more young people in China seem     3       (know) little about classical Chinese literature. However, western culture is becoming popular. More and more parents tend to send their children for overseas studies. Meanwhile, western festivals are becoming     4       (extreme) popular in China while some traditional festivals are being forgotten.

As for the     5       (lose) of some traditional Chinese culture, there are many reasons. For one thing, we haven't attached enough importance     6     our traditions. For another, some people think traditional culture lacks novelty (新奇) and can't keep up with the pace of modern life, while the western culture is more     7     (interest).

However, the traditional Chinese culture, after thousands of years' development, I believe， can never    8     (replace). Therefore, it's time for us Chinese to take some effective     9       (measure). First of all, it's necessary that we should have a clear and deep understanding of its value. Meanwhile, we must do     10     we can to protect and spread our traditional culture. It's convincing that we will keep our traditional culture alive with our joint efforts.

Awakening of Insects, which     1    (signal) a rise in temperature and increased rainfall, falls on March 5 and ends on March 19 this year.

Awakening of Insects refers to the fact     2     animals sleeping in winter     3    (awaken) by spring thunder and that the earth begins to come back to life. It is an     4    (extreme) important time for farmers and is widely seen as the beginning of     5    busiest time for agricultural work. During this period, most parts of China experience the quickest rise in temperatures, with the average level reaching above 10 degrees Celsius,     6     there is a marked increase in sunshine, which provides good natural     7    (condition) for farming.

Hibernating animals wake up, and so do fish. They swim from deep water to shallow water     8    search of food, mating and bearing young. It is a good time for fishing. Fishing can provide mental and physical     9    (relax), especially for people living in the city. Driving to the suburbs, bathing in the sunlight, enjoying the singing birds, fragrant flowers and     10    (wave) willows make for a perfect weekend in spring.

The 500-meter Aperture Spherical Radio Telescope（FAST）, also known as China's Tianyan or "Sky Eye", has     1    （official）opened to global scientists since April, 2021.

As we know, radio telescopes    2    （design）to "listen" or "receive" signals emitted from the universe. With specialized antennas（天线）and radio receivers, these telescopes can detect radio waves from stars, galaxies and black holes. The data collected in turn help scientists    3    （good）explore the universe. It will also be used occasionally to search for alien life.

The giant radio telescope will also help find more pulsars（脉冲星）, which send out steady signals and waves in a regular rhythm. Scientists use pulsars    4    （study）the extreme states of matter, measure cosmic（宇宙的）distances and track time in an ultra-precise（超精密）way. So far, it    5    （discover）more than 240 pulsars.

    6    （locate）in southwest China' s Guizhou Province,    7    largest single-dish radio telescope of the world was completed in 2016. It was put to use    8    January 11, 2020. FAST is now the only "Sky Eye"    9    humans can use to observe cosmic waves. It has immense potential to detect fast radio bursts and gravitational waves,     10    （provide）data support for research into the physical process of the Big Bang, according to experts at the NAO.
