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.

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.”

The Lunar New Year     1     (celebrate) by around 1.5 billion people across the world.

Lunar New Year     2     (vary) in different countries, but celebrations usually involve families gathering together for feasts. Schools and     3     (business) shut for a few days as the celebrations take place. Traditional foods include dumplings, rice cakes and noodle soup,    4     are thought to bring happiness and wealth. Spreading good fortune is a major theme, and firecrackers are lit     5     (drive) evil spirits away. Parents and grandparents give children money in envelopes. There are parades (游行) and performances,    6     (include) lion dances and dragon dances. Chinese New Year is the     7     (large) Lunar New Year celebration, and takes place over 15 days, ending in a lantern festival.

The Chinese zodiac (十二宫) is divided     8     12 blocks. Each block lasts a year and is represented by     9     animal. This year is the Year of the Ox. The date for Lunar New Year is worked out through the traditional Chinese Lunar calendar, which is based on the Moon's     10     (move). It depends on the new moon arriving in Asia between January and February.
