21、Do you ever get the feeling that you’re being watched? Well, you might be right.
According to a study published in Nature on June 23, astronomers have found that 1,715 stars have had a direct view of Earth since humans have been here.
In order to do this, scientists used a previous method that looked for life on other planets. But instead, they changed the method so it could try to determine what places could see us.
The team looked at 331,312 stars within 326 light-years of Earth, with each light-year equaling 9.4 trillion kilometers. Out of all those stars, only 1,715 of them could see Earth within the last 5,000 years, with an extra 319 stars that will be able to see us in the next 5,000 years.
“When I look up at the sky, it looks a little bit friendlier because it’s like, maybe somebody is waving,” said Lisa Kaltenegger, director of the Carl Sagan Institute at Cornell University, US, and the study’s lead writer.
If a planet circling around one of those 1,715 stars is home to advanced life, they could easily see that there is life here because of the oxygen on Earth. If that didn’t give it away, then the radio waves we have sent out into space would also be an indicator. In fact, human-made radio waves have already travelled through 75 of the closest stars on Kaltenegger’s list.
Why haven’t we heard from anyone yet, then?
It takes a long time for messages to travel between star systems. By the time a message could be received, that advanced civilization would probably not exist anymore.
Alan Boss, a scientist at the Carnegie Institution for Science in the US who wasn’t part of the study, wrote in an email that this long time would limit the chances for different life to exchange “emails and TikTok videos”.
“So we should not expect aliens to show up anytime soon,” Boss said.
【1】How many stars will be able to see us in the next 5,000 years?
A．1,715
B．2,034
C．1,396
D．319
【2】What does the underlined word “that” in paragraph 6 refer to?
A．The oxygen on Earth.
B．Advanced life.
C．A planet circling around one of those 11,715 stars.
D．Human-made radio waves.
【3】What could prevent humans from exchanging messages with aliens according to Boss?
A．Human-made radio waves cannot travel far.
B．Aliens don’t exist.
C．They cannot understand each other.
D．It takes a long time for messages to travel.
【4】What is the purpose of the text?
A．To raise reader’s interest in Aliens.
B．To present new findings published in a study.
C．To discuss if there is advanced life on other stars.
D．To explain how messages travel between different star systems.
22、Most of us use web browsers（浏览器）out of habit. However, there are a lot of similar apps for us to choose in the appstore. They serve the same purpose: visiting a website. So if the differences are minimal, why bother looking for something else?
As a matter of fact, a new type of internet navigator（导航器）, called a private browser, has emerged over the last three years. What stands out is that they minimize the data gathered about us by blocking the technologies used to track us, when most mainstream browsers, such as Chrome from Google, have been trying to develop a new way to target us with ads.
Private browsers generally rely on something called private mode, which is a browsing session that does not record a history of the websites you have visited. Firefox Focus, DuckDuckGo and Brave are all similar private browsers, but with some important differences.
Firefox Focus, available only for mobile devices like iPhones and Android smartphones, is the basic one. You input a web address and, when done browsing, hit the trash icon to erase the session. Quitting the app automatically purges the history.
The DuckDuckGo browser, also available only for mobile devices, is more like a traditional browser. The company says it is more focused on privacy because its ads do not track people’s online behavior. When done browsing, you can hit the flame icon at the bottom to erase the session.
Brave is also more like a traditional web browser. It includes a private mode that must be turned on if you don’t want people scrutinizing（仔细检查）your web history. Brave is so aggressive about blocking trackers that in the process, it almost always blocks ads entirely. The other private browsers block ads less frequently.
For most people, not seeing ads is undoubtedly a benefit. Brendan Eich, the chief executive of Brave, said, “If everybody used Brave, it would wipe out the tracking-based ad economy”.
Count me in.
【1】How does the author feel about private browsers?
A．Enthusiastic.

【2】What makes private browsers different from mainstream browsers?
A．Private browsers can recommend personalized ads.
B．Private browsers record a history of browsing websites.
C．Private browsers provide a protective screen for our data.
D．Private browsers are developing new ways to track the users.
【3】What does the underlined word “purges” in Paragraph 4 probably mean?
A．Preserve.
B．Remove.
C．Perceive.
D．Record.
【4】What may be the purpose of this passage?
A．To call on the netizens to raise their awareness of privacy security.
B．To inform users about the three new private browsers.
C．To introduce the latest technologies in developing browsers.
D．To teach readers how to use private browsers.
23、Flying devices called drones(无人机) may be one of the most important technologies of the future.
The number of jobs for people who know how to design, build and control them is increasing. Because of this increase, several U.S. universities have started offering degrees in unmanned aircraft systems, or UAS.
One of these universities is the University of Washington in Seattle. Ward Handley is seeking a master’s degree in UAS at the university. When the drone program first began, he did not think it was a good idea. “Drones can be used to invade privacy(侵犯隐私).” He said. But later, Handley changed his opinion. He said, “I think there are good enough purposes for them.”
The FAA (the part of the U.S. government that controls air travel and traffic) is creating new rules to control the use of drones, however. A new law requires drone owners to register(登记) their drones. People who do not register their drones could face fines of up to US$20,000.
The new rules may also present problems for students. One problem is finding a legal place to fly.
Students at Blue Mountain Community College fly inside the college gym. In Seattle, University of Washington students test their drones in a big room.
Christopher Lum, a scientist at the University of Washington, helps students explore how drones can safely share the sky with regular aircraft. Lum explained why they test drones inside a building, “We need to register our aircraft and get permission to fly outside. That process can take months.”
At this time, Kansas State University is the only school with permission to offer unmanned aircraft flight classes to students outside. The FAA selected Kansas State University and 15 other universities to be part of a national research group.
Lum and some of his students recently moved their research to Australia. Australia has fewer rules limiting drones. A professor at Western Washington University also took his department’s drones to Canada for the same reason.
【1】Degrees in UAS were created in several U.S. universities because of ________.
A. the increasing interest in the field
B. the increasing employment opportunities
C. the support from the government
D. the development of this technology
【2】Why didn’t Handley think the drone program was a good idea at first?
A. Drones can be used for bad purposes.
B. The use of drones was very limited.
C. Few people can benefit from the program.
D. The university didn’t attach great importance to the program.
【3】According to Lum, why does he teach flight classes inside a building?
A. It’s safer for the students.
B. It’s very expensive to register the aircraft.
C. It takes a very long time to get official permission.
D. He hasn’t got permission from the university.
【4】What can we infer from the last two paragraphs?
A. Australia is promoting the use of drones.
B. Kansas State University is the first to offer a UAS degree.
C. Australia has fewer rules than Canada to control the use of drones.
D. The U.S. has more rules than Canada to control the use of drones.
24、Giving your brain a workout
Mental agility does not have to decline with age, as long as you keep exercising your mind, says Anna van Praagh.
A. Use your brain and it will grow — it really will. This is the message from neuropsychologist Ian Robertson, professor of psychology at Trinity College, Dublin and founding director of the university's Institute of Neuroscience. His book, Puzzler Brain Trainer 90-Day Workout, contains puzzles which he devised to stretch, sharpen and stimulate the brain. The puzzles, from ‘memory jogs’ to Sudoku to crosswords to number games are all-encompassing, and have been specially formulated to improve each and every part of the brain, from visual-spatial ability to perception, attention, memory, numerical agility, problem-solving and language.
B. Professor Robertson has been studying the brain for 57 years, in a career dedicated to changing and improving the way it works. During this time there has been a remarkable paradigm shift in the way scientists view the brain, he says. “When I first started teaching and researching, a very pessimistic view prevailed that, from the age of three or four, we were continually losing brain cells and that the stocks couldn't be replenished. That has turned out to be factually wrong. Now that we know that the brain is “plastic” — it changes, adapts and is physically sharpened according to the experiences it has.”
C. Robertson likens our minds to trees in a park with branches spreading out, connecting and intertwining, with connections increasing in direct correlation to usage. He says that the ‘eureka’ moment in his career — and the reason he devised his ‘brain trainer’ puzzles — was the realisation that the connections multiply with use and so it is possible to boost and improve our mental functions at any age.‘Now we know that it's not just children whose brains are “plastic”,‘he says. ‘No matter how old we are, our brains are physically changed by what we do and what we think.’
D. Robertson illustrates his point by referring to Dr Eleanor McGuire's seminal 2000 study of the brains of London taxi drivers. That showed that their grey matter enlarges and adapts to help them build up a detailed mental map of the city. Brain scans revealed that the drivers had a much larger hippocampus (the part of the brain associated with navigation in birds and animals) compared with other people. Crucially, it grew larger the longer they spent doing their job. Similarly, there is strong statistical evidence that, by stretching the mind with games and puzzles, brainpower is increased. Conversely, if we do not stimulate our minds and keep the connections robust and intact, these connections will weaken and physically diminish. A more recent survey suggested that a 20-minute problem-solving session on the Nintendo DS game called ‘Dr Kawashima's Brain Training’ at the beginning of each day dramatically improved pupils' test results, class attendance and behaviour. Astonishingly, pupils who used the Nintendo trainer saw their test scores rise by 50 per cent more than those who did not.
E. Robertson's puzzles have been designed to have the same effect on the brain, the only difference being that, for his, you need only a pencil to get started. The idea is to shake the brain out of lazy habits and train it to start functioning at its optimum level. It is Robertson's belief that people who tackle the puzzles will see a dramatic improvement in their daily lives as the brain increases its ability across a broad spectrum. They should see an improvement in everything, from remembering people's names at parties to increased attention span, mental agility, creativity and energy.
F. ‘Many of us are terrified of numbers,’ he says, ‘or under-confident with words. With practice, and by gently increasing the difficulty of the exercises, these puzzles will help people improve capacity across a whole range of mental domains.’ The wonderful thing is that the puzzles take just five minutes, but are the mental equivalent of doing a jog or going to the gym. ‘In the same way that physical exercise is good for you, so is keeping your brain stimulated,’ Robertson says.‘Quite simply, those who keep themselves mentally challenged function significantly better mentally than those who do not.’
G. The puzzles are aimed at all ages. Robertson says that some old people are so stimulated that they hardly need to exercise their brains further, while some young people hardly use theirs at all and are therefore in dire need of a workout. He does concede, however, that whereas most young people are constantly forced to learn, there is a tendency in later life to retreat into a comfort zone where it is easier to avoid doing things that are mentally challenging. He compares this with becoming physically inactive, and warns of comparable repercussions.‘As the population ages, people are going to have to stay mentally active longer,’ he counsels. ‘We must learn to exercise our brains just as much as our bodies. People need to be aware that they have the most complex entity known to man between their ears,’he continues, ‘and the key to allow it to grow and be healthy is simply to keep it stimulated.’
【1】Which TWO of the following are claims that Roberson makes about the puzzles in his book?
A．They will improve every mental skill.
B．They are better than other kinds of mental exercise.
C．They will have a major effect on people’s mental abilities.
D．They are more useful than physical exercise.
E．They are certain to be more useful for older people than for the young.
