an important part of communications networks, like cellphones, TV, and the Internet.Others are used to track weather and climate information, create maps of the earth, operate navigation (导航) systems like GPS, and take photos of the earth, the sun, other planets and deep space.Right now, there are about 1，000 artificial satellites orbiting the earth.The International Space Station (ISS) is also a kind of satellite, with room for people to live on it.SpaceX, the American technology company, began launching groups of satellites in 2019 and launched 60 satellites into space on January 29, 2020.SpaceX plans to create a network of 12，000 satellites first.It says that the network, known as Starlink will help provide better Internet service for remote parts of the world.However, astronomers say the growing number of satellites orbiting the earth is causing a problem.Satellites are made of metal that reflects sunlight.This makes them show up in the night sky as bright, slowmoving dots.The Starlink satellites take three to five minutes to cross the viewing area of a telescope.During that time, they may pass directly in front of the object an astronomer is trying to look at, hiding it from view.Besides, the light from the satellites is so bright that it makes it impossible to see the weaker light of distant stars and planets.学科网（北京）股份有限公司Large groups of satellites like the Starlinkknown as “satellite constellations (卫星星座)” give off radio signals of their own and reflect radio waves coming from the earth.These extra signals interfere with radio waves coming from places further away in the galaxy.While it might be possible to build satellites with surfaces that dont reflect light, making satellites that dont interfere with radio waves is a different story.There are no rules about who can launch a satellite, or how many satellites can orbit the earth at one time.The International Astronomical Union (IAU), a group made up of professional astronomers worldwide, wants to work with the companies that design and launch satellites and the governments that make laws and regulations.They say it is important to study the impact of having so many satellites and to make rules to protect the night sky.4What does the first paragraph mainly talk about?AHumans ambition to launch satellites.BThe various functions of artificial satellites.CHumans achievements in space exploration.DThe difference between satellites and the ISS.5What is the problem of the Starlink satellites according to the astronomers?AGiving off too much light.BMoving too slowly in space.CBadly affecting the study of space.DAlways hiding themselves from view.6What does the author try to convey in the last paragraph?AThat people shouldnt abuse outer space.学科网（北京）股份有限公司BThat the IAU will stop launching satellites.CThat astronomers arent in favour of exploring space.DThat the companies should work with the governments.7What is the structure of the text?ABC DCLots of ancient treasures have been uncovered by researchers on the island, Chrysi, which was devoted to making a precious purple dye (染料) from sea snails thousands of years ago.The researchers found plenty of shells of sea snails in several small buildings in the settlement of Minoans (属于米诺斯文化的克里特人) on Chrysi those sea snails are called murexes, which have the purple substance (物质) in their bodies.In the large building, researchers found ancient work desks, stoves, buckets, a stone staircase and precious jewels and metals.These things suggest that people in the large building managed the settlements production of the purple dye and the trade with buyers who visited the island by ship.The buyers paid for the goods using precious metals and jewelry.Researchers have studied the Minoans settlement on Chrysi since 2008, having many discoveries, including the remains of large carved stone tanks near the waterline on the beach.Based on their earlier work, researchers suspect that the tanks were used to farm the sea snails, murexes, to increase their numbers and reduce the work of harvesting them from the sea.When murexes grew up in the tanks, they were probably used by the Minoans to produce the purple dye.Researchers say the Minoans on Chrysi made the purple dye from murexes about 4，000 years ago.But some people dont believe that the purple dye was made from murexes on 学科网（北京）股份有限公司Chrysi at that time.They state, “Why didnt those ancient people use cheaper plants to produce the purple dye？” Deborah didnt think so.He told Live Science, “Through our study, cheaper plant substitutes did not come around until the Middle Ages (5 AD15 AD).And the purple dye produced by the ancient Minoans had many characteristics similar to the purple substance inside murexes bodies.”Murexes can make a small amount of the purple substance inside their bodies, using it as a poisonous defense against other creatures.It takes thousands of the sea snails to produce enough purple dye to color a single dress.Its a difficult and sometimes dangerous task.There was danger and discomfort involved in harvesting these creatures.Strength was required to break open their shells, and the smell was terrible.8.The discoveries in the large building show that Chrysi _Awas the first island to make the purple dyeBproduced different dyes from plantsCmight have a relatively developed economyDwitnessed the Minoans fight against outsiders9Stone tanks on Chrysi were likely built to _Acollect drinking waterBmake murexes more availableCkill murexes caught in the seaDhelp color the cloth and other objects10What did Deborah try to express in her words?APeople can gain the purple dye from plants.学科网（北京）股份有限公司BThe Minoans farmed murexes mainly to sell their meat.CSome people doubt the source of the Minoans purple dye.DThe Minoans gained the purple dye most possibly from murexes.11What can we learn from the Minoans process of gaining the purple dye?AThe Minoans were not encouraged to go to sea.BThe purple dye made by Minoans might be valuable at that time.CThe task of catching murexes on the sea can be fun.DThe purple dye might be unpopular with many Minoans.DMath anxiety is an annoying fear of math, and it affects the classes college students select and the careers they pursue.As a cognitive (认知的) scientist, I am concerned that it prevents students who otherwise have the ability to succeed in STEM (Science, Technology, Engineering and Mathematics) from doing so.Math anxiety starts at a young age for both sexes.My research team found that as early as the first and second grade, nearly half of students indicate they are “moderately nervous” to “very, very nervous” about math.A quarter of students attending fouryear colleges experience moderate or high levels of math anxiety.And one study found that, for 11% of American university students, the anxiety is so severe that they have to seek for counsel.Sadly, the US.Bureau of Labor Statistics indicates that employment in mathheavy positions will escalate by 28% by 2026.It is much faster than the average for all careers.However, my own research and other studies show that we are not doing enough to address math anxiety.How do we solve the problem and ensure young Americans pursue opportunities that qualify them for STEM jobs of the future? We can work to bring math to those who might shy away from 学科网（北京）股份有限公司it.Requiring that all students take courses that push them to think empirically (以经验为主地) with data, regardless of the major, is one such approach.Employers should encourage applications from college students with diverse educational interests in their STEMrelated internships (实习).Dont only seek for the computer science majors.This means potentially taking a student who doesnt come with all the computation skills in hand but does have a good attitude and willingness to learn.Then they can provide advanced math and computational training for those college students as part of career development.Moreover, we need to reject the social acceptability of being bad at math.You do hear many people talking about “not being a math person”When we repeat negative feelings like that to ourselves and each other, we fear math more.12What makes the author worried according to Paragraph 1?AThat there are few STEMrelated majors.BThat the fear of math will lead to severe math anxiety.CThat college students fail to select proper professions.DThat students fear of math prevents their success in STEM.13What did the authors research team find?AMath anxiety is common at all age levels.BGirls tend to perform better in math than boys.CCollege students can overcome their math anxiety.DMath anxiety can be classified into different degrees.14What does the underlined word “escalate” in Paragraph 3 mean?AImprove. BIncrease.学科网（北京）股份有限公司CDrop. DRecover.15What does the author advise employers to do?AOffer students free STEMrelated internships in colleges.BAssist colleges in improving students computation skills.CWelcome students with different majors to work for them.DProvide students with chances to develop their interests.阅读七选五For many people, the costs associated with a daily commute (通勤) to a distant work site can be annoying.If children are involved, then there are the added expenses of professional childcare while the parents are at work._16_Some athome jobs are extensions of household duties already being performed, such as laundry services, childcare and food preparation.Athome parents with suitable skills can operate their own daycare centers for the working parents, for instance._17_ So it is an ideal homebased business for experienced parents.Some athome jobs can be more creative in nature, such as the creation of specialty (特色) crafts or foods.
