Electric vehicles (EVs) are a strong weapon in the world’s efforts     1     global warming, But the effects of EVs depend on which country you are in, new research shows.

The researchers compared gas emissions (排放) caused by charging an EV to drive 100 kilometers with the emissions     2     (come) from an average gasoline car driven the same     3     ( distant).

Countries     4     charging an electric vehicle is     5     (clean) than driving a gasoline-powered car use a lot of hydroelectric (水电), nuclear or solar power. Data suggests that an electric vehicle in Poland actually     6     (create) more carbon emissions because its electric system depends so much on coal. In other European countries, however, EVs result in reduced emissions.

Germany creates a lot of electricity from the sun and wind. But they do not add to the electricity system     7     (equal) throughout the day. For this reason, the amount of carbon emissions saved by driving an EV depends on the time of day when it     8     (charge). Charging in the afternoon, when there is more sun and wind, saves 16 to 18 percent more carbon than at night when electricity systems are more likely     9     (use) gas or coal.

The gap in emissions between electric and gasoline powered vehicles has narrowed in recent years. In Europe, carmakers have been required to meet EU carbon reduction standards. They have made their gasoline engines more fuel-efficient. As     10     result, the carbon emissions of new gasoline-powered cars in Europe fell by an average of 25 percent between 2006 and 2016.

The Special Olympic athlete

For athlete Eric Williams gold medals are nice, but good sportsmanship is more important. Eric has a low mental     1     （able）but this does not stop him from     2     （take）part in the Olympics. In 2005 Eric     3     （compete）in running races and the long jump. He said, "I've been competing in the Special Olympics ever     4     I was at high school. It's really     5     good experience. You get to meet a lot of athletes and volunteers and make different     6     （kind）of friends.” John Corbett, an organizer of the Special Olympics said, “He always does his     7     （good）and has a wonderful time in the process. He     8     （true）appreciates（感激）all the people around him     9     are trying     10     （help）, and he makes that appreciation known.” Let's hope Eric wins more medals in the next Special Olympics!

Facial recognition is a technology that     1     (use) facial features to identify a person. Today, facial recognition is used in a variety of ways,     2    allows you to unlock your phone, go through security at the airport, and buy products at stores.

One of the major     3     (advantage) of facial recognition technology is safety. The police use the technology to uncover criminals or find missing children or seniors. Airports are     4     (gradual) adding facial recognition technology to security checkpoints; the U.S. Department of Homeland Security predicts that it     5    (adopt) on 97 percent of travelers by 2023. When people know they are being watched, they are more likely     6    (obey) rules.

Facial recognition can add conveniences. You will start to be able to check-out at stores without     7     (pull) out money or credit cards - your face will be scanned.

The     8     (big) drawback of facial recognition technology in most people’s opinions is the threat     9     an individual’s privacy. In fact, several cities have considered or will ban real-time facial recognition use, including San Francisco, Cambridge, Massachusetts, and more. Because people don’t want to take     10     risk of revealing personal information to enjoy these benefits.

The year 2021 has brought plenty of choices. According to news website TMT, 188 Chinese animated series have come out this year on Tencent Video, iQiyi, Youku and Bilibili. Among them are new seasons of older shows,     1    (include) the fourth season of Douluo Dalu and the second season of Shaonian Gexing.

Nearly half of the new works are in guofeng style, or “traditional Chinese style”. The stories are mostly based on or adapted     2     Chinese legends or literature. For example, The Westward     3     (original) comes from Journey to the West.

Modao Zushi is another example,     4    is based on fiction, but the animation involves many    5    (element) of traditional Chinese culture. For example, it     6     (combine)the visual style of traditional Chinese water-ink paintings and gufeng music from the flute and guqin. As our society gets     7    (wealthy), it’s natural that Chinese people have reclaimed greater pride and confidence in their own cultural roots. This is     8    these guofeng animations are rising in China.

“Chinese anime is no longer     9     unfamiliar term,” noted Animation Magazine.“Chinese companies are devoted to     10    (support) the development of more excellent Chinese original anime works.”

Nowadays, Chinese people     1    （impress）by the progress of our country, which is extremely exciting. We     2    （make）great progress in science and technology in the past decades, especially the progress in space exploration. We conquered the space, and the conquest represents a visible proof of our nation’s     3    （strong）.

The advances in space technology will be     4    （benefit）to us in the long run. Thanks to communication satellites, we can see television pictures transmitted（传送）across the globe, and we can communicate with our friends and business partners     5     are far away from us. Without exploring the space, we could never figure out its mysteries（奥秘）or broaden our horizons far beyond the boundary of     6     planet Earth.

Besides, what distinguishes us from animals     7    （be）that we know we need to explore. Actually, the space technology is not only the search     8     knowledge but also a mirror of the development of our nation. We will become proud of our motherland, We will devote ourselves to     9    （develop）our country.

China is growing stronger and stronger, and it will never fall behind in the progress of science and technology. We are looking forward to new     10    （breakthrough）, and we believe they will come up in the near future.
