About 15 years ago，scientists developed the tools t

11、o detect these “exoplanets”．Since then，they’ve spotted about 450.Most of the findings include one，two or three enormous gas-filled planets orbiting a star. But on August 24,2020，a group of European scientists announced an unusual discovery.They say they’ve identified a solar system that’s similar t

12、o ours.It consists of as many as seven planets orbiting a sun-like star.The star is over 100 light years away from us. The five planets that the scientists are most certain about are large－up to 25 times the size of Earth.According to Christophe Lovis，one of the scientists behind the finding，these

13、five planets are similar to Neptune (海王星)．“They’re made mainly of rocks and ice，” he said.“They’re probably not suitable for people to live in.” There are also signs of two more planets.One is thought to be similar to Saturn (土星)．The other may be the smallest exoplanet ever spotted.It’s only slight

14、ly larger than Earth.Because it’s so close to its star，the small planet takes just over a day to orbit it. Spotting faraway planets is challenging.The blazing light given off by the star they orbit makes the planets hard to see.That is why we cannot yet be 100% sure about these seven planets.The sc

15、ientists haven’t actually seen them.Instead，they used a powerful telescope to study the star for six years.The star gave the scientists clues about the planets that orbit it. According to Alan Boss，a scientist who wasn’t involved with the study，“this method is best for finding the big guys.” But，he

16、 said，the discovery shows spotting smaller planets is also possible. “The really nice thing about finding systems like this is that it shows there’re many more out there，” says Boss.“Mother Nature really had fun making planets.” 1．In another solar system discovered by the European scientists，_____

17、___. A．the star orbited by seven planets is over 100 light years away from the sun B．a(chǎn)ll the seven planets are much larger than our earth C．none of the seven planets is suitable for people to live in D．five planets are made mainly of rocks and ice 2．According to the passage，what makes it diffic

18、ult to find those exoplanets? A．The tools which are used to detect them. B．The long distance between them and our earth. C．The light given off by the star they orbit. D．The too long time needed to detect them. 3．It is inferred from the passage that Alan Boss________. A．has always been supporti

19、ng the European scientists B．believes using a telescope to study small stars is also possible C．thinks the European scientists’discovery is a little unbelievable D．believes there must be another planet with humans living in it 4．The best title for the passage should be________. A．Research on th

20、e Solar System B．Difficulty in Studying Mother Nature C．Scientists’ Contributions to the Universe D．A Lot like Our Solar System Ⅳ.信息匹配 1. Americans are far more knowledgeable about drinks than they were 20 years ago.Witness the Starbucks revolution and you’ll know where the trend goes.Now，

Tea is available in more pla

22、ces than ever.The Tea Association of the United States reports that from 1990 to 1999，annual sales of the drink grew to $4.6 billion from $1.8 billion.“Green tea is seen by consumers as a ‘functional food’”— delivering health benefits beyond food itself，says Vierhile. 3. Recently published studi

24、archers found that drinking one cup of black tea a day lowered the risk of heart attack by as much as 44 percent compared with nontea drinkers，and other studies have suggested that the antioxidants(抗氧化劑) in these socalled real teas can also prevent cancer. 4. One such antioxidant in green tea

25、is ECGC，a compound 20 times as powerful as vitamin E and 200 times as powerful as vitamin C．“When people ask me for something good and cheap they can do to reduce their cancer risk，I tell them to drink real tea，” says Mitchell Gaynor，director of medical oncology at New York City’s Strang－Cornell Can

Among those inspired to become a greentea drinker is Tess Ghilaga，a New York writer who took it up after seeking advice from a nutritionist six years ago.“I’ve never been a coffee drinker，” says Ghilaga,33.“She told me to start drinking green tea for the antioxidant qu
