In fact, most people do believe that aliens exist in some fashion. The

2、 main necessities for life are water and some form of energy source. Not surprisingly, there are some planets, exoplanets and moons that fit the bill. Here are several best chances at finding life in the universe. TRAPPIST-1TRAPPIST-1 is a planetary system a few dozen light-years away, whose discove

3、ry was announced in early 2017. This system consists of seven Earth-like exoplanets orbiting an ultra-cool star, and it is one of our shots at finding possible life beyond our own solar system. TitanTitan is the largest moon of Saturn, the sixth planet from our Sun. This moon could potentially harbo

4、r life but possibly not in the sense that we think. Titan does not exactly fit the description of being in a typical habitable zone. Titan has water, and it has liquid. It just doesnt have liquid water. The water on this moon is completely solid because of the extremely cold temperature. EuropaEurop

5、a is one of Jupiters moons here in our own solar system. It is another candidate due to its potential to hold liquid water. Europa is thought to have all the necessities for life including water, energy sources, and the right chemical build-up. MarsThe Red Planet, the fourth from the Sun, is probabl

6、y one of the most talked-about potential candidates for extraterrestrial(地球外的) life and even for human colonization. Despite some different voices, finding extraterrestrial life on Mars really is a serious possibility. We know by now that we wont find little green men or any intelligent form of life

10、l subjects, but I had my mind set on a life fulfilled by the arts.In fact, I was a victim of a gender stereotype made stronger since birth, that men do science and maths and women do arts or languages. Computer science, technology and physics just did not figure in my teenage world view. Nobody popu

11、lar in my school chose to study those subjects.Reality struck hard when I began attending job interviews and interviewers would say: “Its great that you speak foreign languages, but what else do you do?” Nobody asked my friends who had studied science or technology those questions.A survey recently

12、showed that three of the best-paid jobs for women are in the technology sector. Its a sector that really can change the world. We must show girls that technology has an effect on every industry out there, from fashion to architecture to journalism. Anybody can learn to code and these days its as imp

13、ortant as reading and writing. Ive realized that at university Id achieved the wrong kind of literacy. Not being able to code limit your impact on the world far more than an ignorance of great literature.Now I have a five-year-old daughter. I dont want her to blindly follow gender roles the way I di

14、d. I want her to know the fact that a science or technical degree will not limit her creativity but expand it and broaden her horizons far more than my arts background could. Im exposing her to Minecraft and apps, which help improve analytical thinking and problem solving skills. Im hoping that my d

18、neo, where they had set up a set of experiments to look at the ecological effects of small creatures: termites (白蚁).Termites get a bum rap. They make headlines for chewing up billions of dollars of property each year in the U. S. And they are responsible for something like two percent of global carb

19、on emissions, simply as a result of their huge populations and preference for chewing through carbonrich materials. A whole industry is aiming at killing them.But they play a key role in many natural ecosystems. Scientists have known for years that in tropical (热带的) forests, termites chew up fallen

20、leaves and dead wood, keeping the fallen material under control and letting nutrients from the dead material back into the system to be used by other plants, insects, and animals. But they didnt know exactly how important the insects were in keeping the forest healthy and functional, so they removed

21、 termites from a particular spot in the forest and saw how it responded.As luck would have it, Hannah Griffiths and her colleagues started their experiment when the forest was hit by an extreme drought (干旱). During the non-drought years, they saw there wasnt much difference between the normal plots

22、and the ones where theyd removed the termites. But during the drought, the effects were marked. What they found was unexpected: in the termite-rich areas, the soil stayed slightly wet, more tree seedlings sprouted (抽芽), and the system was full of activity despite the long, hard dry climate.For Griff

23、iths, it was only because they happened to study the drought that they could pick out the real importance of termites to the system, she points out. “And that rings alarm bells in my head,” she says, “because it makes me think, well what else dont we know? If we start damaging biological communities

24、, we dont know what that will do.”28. Which of the following best explains “a bum rap” underlined in Paragraph 2?A. Unfair blame. B. Wide popularity. C. Public attention. D. Special preference.29.

27、hink twice before damaging a species. D. We should study the drought to improve the system.D“Big tobacco” is what the bosses of several large technology firms have started calling Facebook. Being compared to the tobacco giants is far from praise, but it is not the only wide-spread analogy(比拟). A low

28、er blow is the suggestion that Facebook may become like Yahoo, the once high-flying internet firm that fell.Even a year ago the idea would have been unthinkable. But since January Facebook has become trapped in a series of misjudgments and missteps. It became clear that it had done too little to sto

29、p Russian interference(干涉) in Americas election in 2016. It had to admit that it had shared the personal data of 90million users with outside firms without permission.The comparison to Yahoo is imperfect. Even at its peak Yahoos business was never as large and profitable as Facebooks. One of the mai

30、n reasons Yahoo declined is because it lost out to a powerful competitor, Google, in online search; Marissa Mayer, its boss from 2012 until its sale to Verizon last year, was unable to restore advertisers or employees confidence as users left.But people who watched Yahoos falling see similarities. E

31、xecutive(主管) turnover was a leading indicator of its decline; before Ms. Mayer was hired Yahoo went through four chief executives in three years. Mr. Zuckerberg, who controls the majority of Facebooks voting shares, is not leaving, but many top executives are. This year several have announced their

32、departures, including Facebooks chief security officer.When advertisers faith in Facebook has been shaken, politicians in Washington are running out of patience with the company. Lawmakers inspection of the firm is causing it to be more cautious about how it uses data for targeting advertisements and about what information it makes available to outsiders.Mr. Zuckerberg and Ms. Sandberg are under pressure to prove to employees
