11、e of exploring it. The news had the effect of a bomb after five years of communication and development for this space exploration project. And yet, a few months before this announcement, the two houses of the US Congress voted a law to guide future NASA tasks. Among these tasks was an inhabited trip
12、 to Mars in 2033.In the meantime, NASA is focusing on the Mars 2020 mission by building its rover(漫游者), which will be equipped with a series of new scientific instruments. This new machine will also look a lot like Curiosity which landed on the red planet in 2012. The mission Mars 2020 aims to asses
13、s the livability of the planet and possibly identify potential tracks of life yesterday and today.At a recent press conference, former US astronaut Tom Jones announced that NASAs current budget could not solve some technical problems for 25 years. Thus, it postpones the first inhabited mission of th
14、e agency to Mars in 2043. The subject concerned mainly mentioned many damages that will affect the body of astronauts.Indeed, the trip to Mars could be completed in nine months by considering the current technologies and the moment when the planets are closer to each other. However, periods of weigh
15、tlessness that are too long may, in particular, cause a lack of calcium. In fact, it influences the bones of astronauts. In addition, this can lead to significant damage of vision.A quarter of a century is needed to develop new technologies to solve these problems. Forexample, there is the question
16、of developing nuclear propulsion(推进)systems. Indeed, it could reduce travel times. Finally, there is also the idea of designing something to allow astronauts to hibernate (冬眠) during the trip!21.

The update of new devices.BWhen Noah Ready-Campbell was a young adult, he worked for his fathers construction company. Back then, he dreamed of a day when robots might take over the dirty, repetitive(重复的)p
19、arts of his job, such as earth moving. Years later, Ready-Campbell left his job as an engineer with Google to make that dream come true.Ready-Campbell formed a company called Built Robotics, which develops technology to produce self-driving heavy equipment. Ready-Campbell says the companys goal is t
20、o make construction safer, faster and less costly. The construction industry struggles to find skilled workers and faces a growing number of unfinished projects. But self-operating machines are changing the nature of building.Workers at Berich Masonry in Englewood, Colorado, recently spent several w
21、eeks learning how to operate a robot called SAM, or the Semi-Automated Mason. SAM is a $400,000 machine from the company Construction Robotics, It can lay 3,000 bricks in eight hours. Thats several times more than a human bricklayer can do in the same period. But humans are still needed to load bric
22、ks into the SAM and make sure it works right. Bricklayer Michael Walsh says the SAM lessens the load on his body. But he doesnt think it will take his job.Brian Kennedy agrees, too. His organization supports the rights of construction workers in the United States and Canada. Kennedy says the union i
23、s not worried that machines will replace human workers any time soon.The rise of construction robots comes as the building industry faces a severe decrease in labor supply. One recent study showed that 70 percent of construction businesses have a difficult time finding skilled workers. Mike Moy head
24、s a mining operation for the building materials supplier Lehigh Hanson. He says its difficult to find people who even know how to operate some of the necessary equipment. “Nobody wants to get their hands dirty any more. They want a nice, clean job in an office,” he noted.28. What does the first para
25、graph say about Noah Ready-Campbell?A. He enjoys doing repetitive work.B. He is now an employee of Google.C. He used to work in construction field.D. He joined Google to realize that dream.29.

27、ch faster than humans.31. In Mike Moys opinion, what prevents many construction businesses from finding skilled workers?A. Their low pay. B. Their potential risks.C. Their heavy work loads.D. Their poor working conditions.CIf you get your news from social media,you are faced with a daily number of h
28、oaxes(恶搞),rumors,and misleading news.When its all mixed in with reliable information from honest sources,the truth can be very hard to judge.In face,my research teams analysis of data from Columbia Universitys Emergent rumor tracker suggests this false information is just as likely as to spread craz
29、ily as reliable information.Our research shows that in view of the structure of our social networks and our limited attention, it is unavoidable that some popular unconfirmed information will spread quickly, regardless of their quality. Even if individuals tend to share information of higher quality
30、, the networks as a whole is not effective at telling the difference between reliable and fake information. This helps explain all the hoaxes we observe in the wild. Besides, our attention is limited. If we pay attention to a certain topic, more information on the topic will be produced. It s cheape
31、r to fake information and pass it off as fact than it is to report actual truth.We can make our fight against false news more efficiently if we better understand how false information spreads. If, for example, robots are responsible for many pieces of the false news, we can focus attention on detect
32、ing them.To that end, our lab is building a platform called Hoaxy to track and monitor the spread of unreliable information on social media. That will give us real-world data, with which we can inform our imitated social networks. Then we can test possible approaches to fight false news. Hoaxy may a
33、lso be able to show people how easy it is their opinion to be misrepresent by online information and how likely some of us are to share false news online. Hoaxy will join a set of tools in our Observatory on Social Media, which allows anyone to see how false information spread on the Internet.It is
34、necessary that we spend resources on the study of this phenomenon. We need all hands on decks:Computer scientists, social scientists, economists, journalists and industry partners mustWork together to flight against the spread of false information.27.What does the author say about the news from soci
35、al media?A.Its missed and hard to tell its truth. B. Its neither true nor worth believing.C.Its all false and misleads us. D.Its reliable and worth believing.28.Some popular unconfirmed information will spread quickly because of_.A.its higher quality and spreading speed B.its structure of social net
36、works and our limited attentionC.its lower cost of fabrication and passing it of D.the networks not being able to tell the truth effectively.30.Which of the following is NOT the functions of the platform called Hoaxy?A.tracking and monitoring the spread of unreliable news on social media.B.testing p
37、ossible approaches to flight false news.C.helping people to see how true information spread on the internet.D.showing people how easy it is their opinion controlled by online news.31.What is the authors purpose in writing the text?A.To call on people to study and fight against false news together.B.
38、To let all people buy a platform called Hoaxy.C.To warn people how seriously false news spread online.D.To tell people how to prevent false news from spreading.DWhy is it that big life decisions-whether to have kids, marry a specific person, choose one job over another-can be so worrying? Obviously,
39、 it is because they really matter. Yet, on closer inspection, that cannot be the whole story. Other decisions “really matter”, too: whether to seek medical help when you break your leg; whether to use a glove to handle an extremely hot dish. But they are not worrying at all. They are so straightforw
40、ard that it sounds strange even to think of them as decisions.Perhaps what makes decisions worrying is that they matter and there is too much uncertainty to know which option to choose. That sounds more reasonable. But as the US psychology professor Tania Lombrozo points out, if no single option cle
41、arly stands out, then your decision does not much matter. You could just flip (掷) a coin, or, as Lombrozo puts it: “Hard decisions should be easy.” This is Fredkins paradox(悖论), which can be explained as “The more equally attractive two alternatives seem, the harder it can be to choose between then.
42、 But, to some degree, the choice can only matter less.”Since you are unable to know how things will turn out, overthinking is useless. We worry much, as if hoping through great efforts to see into the future. In the worst case, we end up choosing none of the potentially good options, but a very bad
43、one, instead. That applies to the hungry and thirsty donkey (驴), positioned between grass and water, and stays rooted to the spot, thus starving to death.Merely knowing about Fredkins paradox probably will not reduce your tendency to overthinking. But it can provide comfort when a decision turns out
44、 to have been bad. You can remind yourself that you truly could not have known. Alan Watts once observed that the process we call “deciding”-moving gradually towards a decision-is frequently no such thing. Rather, it is just a period of flipping back and forth between options, followed by a sudden a
45、nd semirandom choice. We might as well admit that.32. The author introduces the topic of the text by _.A. offering suggestions on how to face dilemmasB. explaining the reason for peoples worries in lifeC. comparing big life decisions with other decisionsD. throwing doubt on a theory about decision m
46、aking33. Which of the following is in line with Fredkins paradox?A. Sometimes it is not that important what you decide.B. Whatever option you choose is the best one ever.C. There is not so much certainty about your options.D. It is easy 1o decide when your options are similar.34. What is the authors
47、 advice when it comes to making big decisions?A. We should learn from past choices.B. We should stop thinking too much.C. We should carefully weigh each option.D. We should see into the future through efforts.35. What would be the best title for the text?A. What is the secret of making good decisions?B. It is necessary to know about Fredkins paradoxC. Remind yourself the random choice really mattersD. Why do we find it so difficult to make big decisions?.
