Waters may be flowing on the surface of an enormous planet that lies about 120 light-years from Earth, according to new evidence     1     (uncover) by the James Webb Space Telescope.

The investigation with the space-based observatory, one of the most advanced astronomy instruments in operation,     2     (reveal) that the exoplanet (外星球) K2-18b may have some key features of a planet     3     could support bodies of water — and life. Closely orbiting the cool dwarf star K2-18, the exoplanet lies within the star’s habitable, or Goldilocks, zone and is 8.6 times     4     big as Earth. An     5     (analyse) of Webb’s observations found the planet has huge quantities of methane (甲烷) and carbon dioxide in its atmosphere.

The Webb telescope, which can detect infrared (红外) light invisible to the human eye, searched for exactly     6     elements are featured in the planet’s atmosphere. And     7     latest observations of the planet also hint that a very special substance, called dimethyl sulfide (二甲基亚砜), could be     8     (presence) on K2-18b. On Earth, dimethyl sulfide “is only produced by life,” according to NASA. Researchers are not directly suggesting that K2-18b is crawling with alien life. Further research is needed     9     (confirm) the presence of dimethyl sulfide.

And even if scientists confirm the chemical compound’s presence, that doesn’t guarantee life-forms exist there. But this new evidence does expand scientists’ understanding of exoplanets similar     10     K2-18b.

Smartphones are mobile phones that have lots of    1    same features as a personal computer. Technology is moving on very    2    (rapid). Smartphones have become an important part of everyday life for many people. However, they also have negative effects (影响),     3    means some people are giving them up.

Some people think smartphones can cause health problems. Smartphones offer so many ways    4    (communicate) that people are having less face-to-face communication. This can lead to loneliness and     5    (sad). What’s more, all the activities that can be done on phones can lead to fewer real-life experiences. Being less active can influence your health. Finally, some people become nervous if they    6     (separate) from their phone and can’t check their messages or social media.

Others still say smartphones are useful and fun. Smartphones allow you to keep    7    touch with people in different ways. They are really good for video-calling faraway friends and family. You can also get    8     (direction) on them. Having Internet access(访问) on your phone allows you to get news and information—it is really    9    (help) for homework and so are education apps. Smartphones are great entertainment(娱乐) on long journeys. They are fun to use with friends, taking photos and    10     (make) videos.

Recently, a poll(民意调查) finds that although almost three in four adults played sports when they     1     (be) younger, only one in four continue to play sports as adults.

But that decline in interest doesn’t stop parents from encouraging their children to make sports a part of their lives.     2     fact, almost nine in ten parents     3     middle school or high school aged children play sports say that their children benefit     4     great deal or quite a bit from playing sports.

And, while most adults no longer play sports     5     (they), the majority of parents say it is very likely or somewhat likely that their children will continue playing sports when they become adults. One in four parents also hope their children will become     6     (profession)athletes.

“Sports are an important part of a healthy community. They help children and adults maintain a fit     7     (weigh), teach acceptance and teamwork, and expand opportunity for children     8     (live) in poverty(贫困),” said a researcher. “This poll     9     (indicate) that we must continue to encourage children to play sports, but just as important, we must find ways     10     (keep)adults engaged in sports in order to maintain health and well-being.”

As a child, reading was one of my favorite     1     (hobby), and it still is to this day. I've always enjoyed immersing (使沉浸于) myself in the pages of a novel, entirely attracted by fictional characters and     2     (they) stories. One part of the experience that almost always made me feel    3     (disappoint), however, was when my beloved books became movies. And according       4     a recent survey, I'm not the only person who is let down by book adaptations.

SuperSummary, an online resource, wanted     5     (know) the answer to a burning question: Book or movie? The company asked 2,030 people, ages 23 to 62, to answer questions about books    6     had been turned into movies or TV shows.

The results were fairly close. Overall, 34% of people enjoyed the book,       7    (compare) to 27% of people who liked the movie more. Although 82% of people said “screen adaptations help books come to life,” 46% of people argued that movie adaptations “would never be as good     8     the book.”

Perhaps the slight preference for the book over the movie is related to libraries being a little     9     (popular) than movie theaters. I     10     (complete) understand why people might prefer watching a live version of a story on the big screen, but to me, there are few simpler pleasures than getting lost in the pages of a good book.

Hua Zhibing announced     1     June 3 in her blog that she will study in the Department of Computer Science at Tsinghua University in the upcoming semester. Hua is China’s first virtual student     2     (power) by Wudao 2.0,     3     artificial intelligence (AI) system.

    4     really sets Hua apart from any average college student is her amazing learning     5     (able). She can learn much     6     (fast) than any average human being. “If she begins learning at the six year-old level this year, she can reach the level of a twelve year-old in one year,” said Tang Jie, the     7     (develop) of Hua Zhibing. “We aim     8     (teach) her to think and feel like a human being. Now, Hua is     9     (closely) to breaking the Turing Test in painting pictures, writing poems and answering questions. We hope that she will master these basic skills first and then seek breakthroughs in     10     (reason) and feeling.”

It is meant to act     8     a medium through which people can become much     9     (close) to nature. Drinking tea out in nature will create a spiritual connection to the environment and make people feel     10     (relax).

When I was in primary school, I disliked doing exercise. I felt tired when I did any kind of exercise. My parents were really     1     (worry) about my health. One day, after having supper, my father     2    (come) and asked me to have a walk with him in the park. I agreed and we went     3     together. It was hard for me to walk for half an hour. I wanted to give up,     4     my father encouraged me to keep on walking. From then on. I was often asked to walk with my parents. To my surprise, I could walk for an hour in the     5    (five) month. How     6    (pride) I felt! I loved taking exercise gradually. Now I am     7     excellent runner in my school. I take part in the school sports meeting every year.

During all our life, we may face a lot of     8    (difficulty). Don’t be afraid of     9    (they). Please try to face them     10    (brave). After you overcome what you used to be afraid of, you may find how great you are!
