          Feel too old or too stupid to learn a second ：

language? It may be worth peraeven(堅(jiān)持).A study that tracked hundreds of Scottish people for decays gives the strongest evidence that speaking an extra language slows the mental decline that accompanies ageing. The benefits hold regardless of your IQ and even if you learn vour second language as an adult. 

          Previous studies have shown that people with disease(老年癡呆) who are fluent in two languages exhibit symptoms of the condition four or five years later than people who are(只用一種語(yǔ)言的) .However,it has been difficult to explain the effects of knowing multiple languages.

          To resolve the issue,Thomas Bak of the Universi  of Edinburgh,UK turned to the study,which has tracked about l,l00 people bom in 1936 in and around Edinburgh. AH were monolingual English speakers at age 11 ,when they had taken a series of (認(rèn)知的)           Although the study wasn't  designed to investigate language effects,itvv provides a unique research opportunity,says Ellen Bialystok at York University m Toronto,Canada,who was the first to discover that being bilingual delays the beginning of Alzheimer 's  disease .

          853 of the participants were tracked down when they were in their early 70s. Almost 262 of them had learned;to speak at least one additional language and 65 had learned it after the age of 18. Bak gave the participants cognitive tests and compared these with the test scores ：from when they were 11. Those who had learned an extra;language performed better in the cognitive tests in their 70s,indicating that the extra language itself is beneficial.                 Bialystok says the cognitive benefits seen in the;Scottish study agree with her own work on blllngua people with Alzheimer' s  disease,suggesting that thei same beneficial processes are at work:

         How could languages protect the brain? A theory is that people who speak several languages constantly ：activate all the available words in each one before choosing the appropriate expression,giving them some ;：mental exercise.

                            ★ ★ ★ ★ ☆

           Most of us are aware that taking breaks from physical activity is necessary to recover and prevent injuries. Taking breaks in our mental work is equally helpful.

           Recent studies show that those who give in to some kind of distraction once an hour perform better than those who just keep at it without a break. After a while,our brains can't focus so well,and we become unable to continuously treat the task as important. Taking a break allows us to come back to the job at hand with renewed energy and a sense of purpose.

           No matter how much we love our work,we cannot keep creating when we are on empty. Something as simple as a ten-minute conversation with a friend,or watching an inspiring video can give us much needed help,or point us in a new direction if we* re stuck. It is difficult to see things from a new point of view when we come at it the same way all the time. Taking a step away might be just what we need to (恢復(fù)精力) .

           We are not designed to sit around all day. As difficult as being sedentary(需要久坐的) is on our bodies,it's not helpful for our creativity and productivity,either. Getting up for a few minutes and getting our blood flowing and some more oxygen to the brain are a necessary piece of the v^ork day.

          If you know you typically have an afternoon energy slump(銳減)， consider doing exercise during the lunch-time hours. Studies have shown that appropriate activity can boost creativity and productivity for two hours afterward. Plus,the change of scene and focus may just be something you need for your next breakthrough at work.

           The next time you feel guilty about taking a break, consider how much more effective it may make you in the long run.

13. According to Paragraph 2 ,recent studies show.

   A. our brains react negatively to distractions

   B. people are always working without a break

   C. taking breaks from work benefits productivity

   D. taking breaks from physical activity can prevent injuries

14. In the author's opinion,a sedentary lifestyle .

   A. is necessary sometimes

   B. means good productivity at times

   C. cannot be avoided by today's people

   D. is harmftil both physically and mentally

15. The text is meant to show the importance of.

   A. creativity at work

   B. treating work seriously

   C. taking breaks at work

   D. high productivity at work

16. Where does the text probably come from?

   A. A book review.

   B. A research plan.

   C. A science report.

   D. A business report.

             Lots of students do experiments on plants for their science projects. Scientists do this as well. Have you ever heard of a lie detector? It is something that police can use to figure out if you are lying or not. The machine can feel the energy in your body. If your energy moves fast,it shows you are nervous and may be lying. If it is slow and steady,it shows you are relaxed and probably honest.

             Scientists attached these same machines to plants,not to see if they are lying of course,but to see what makes them nervous,what makes them calm,and what makes them excited. They found many interesting things. First,they discovered when live fish were being cut up or live lobsters(龍蝦) were being boiled,the plants got very upset. They seemed to respond to the fear of the living seacreatures.

            Besides,scientists found the plants actually got excited when their owners were coming home. What was even more interesting was that the plants got very excited 'when the owners stepped into the room. It seemed that the plants were so connected with their owners that they could pick up their owners’ intention to come home.

Plants also seemed not to like to be cut. When the owners pulled out a pair of scissors to cut them,they got upset. Scientists tried to frighten the plants and pretended they were going to cut them,but the plants did not get nervous in that case at all. It was as if they could read the owners’ mind. So,when taking care of your plants,remember that they are sensitive and smart.

1. The first paragraph mainly talks about.

   A. why a lie detector is popular

   B. when a lie detector ean be used

   C. how a lie detector works on plants

   D. what a lie detector is and how it works

2. What was the scientists’ purpose of attaching lie detectors to plants?

   A. To help plants grow faster.

   B. To see if plants are good liars.

   C. To see what causes plants* emotional changes.

   D. To help plant owners communicate with plants.

3. The result of the experiment is that.

   A. plants were happy to work with lie detectors

   B. plants got more relaxed when they were alone

   C. plants could"protect themselves when threatened

   D. plants might understand their owners in some way

4. What did the scientists use the scissors for?

   A. Cutting the plants.

        The daily hard work in the office can be extremely exhausting. Staring at a computer screen for eight hours a day seems like modem business practice. It's also a common belief that you 5 re more likely to complete your "tasks if you keep your bottom planted in your chair all day. But that opinion is erroneous. In fact,taking breaks regularly throughout your workday can increase your productivity and creativity as it helps to keep the mental iuices flowing. ,

The study gets to the most important part of what so many of us experience when doing the same task for a long period of time; after a while you begin to lose your focus and your ability to perform the task well. "Basically,if you don 51 take small breaks during the day,you re likely to suffer from exhaustion and won 51 complete your task to the highest level of your ability,” says Alejandro Lleras,the leader of the study.

         In addition,new research shows that your brain can be trained and developed iike a muscle. Mental concentration is part of that training. Just as your muscles  become tired after a workout,so does your brain. It needs a rest to recover and move on.

         So,what can you do if you feel guilty about taking a break during the workday? Remember that taking breaks is a good,necessary thing. We* re trying to prove ourselves and our worth to the company,which makes us think that taking breaks prevents us from achieving our goals,but in fact it's  not. It's  necessary to do your best work.

           Last week,we took part in a press conference at NASA’s Johnson Space Center promoting the release of The Martian movie. We spoke with several NASA officials and an astronaut about their plans to help humans set foot on Mars. They all shared with us the big challenges ahead in order to accomplish that. However,it is something they take seriously,and are determined to achieve.

           In an interview at Space Center Houston,The Martian producer Aditya Sood told us the experience of working on the movie with NASA employees was amazing. He said he enjoyed interacting with folks who tried to solve a lot of difficult problems every day. We got an idea of what Sood was talking about when we interviewed some of the scientists responsible for getting humans to Mars.

           Planetary Science Division Director Jim Green told us that getting humans on the surface of Mars in 2035 is probably too ambitious. They are actually looking to get a “human presence in the neighborhood” by the 2030s,meaning in Mars* orbit. Their goal for landing on Mars is for the 2040s or 50s.

           The spacecraft that will take humans to Mars will be the Orion. It is not quite as futuristic-looking as the spaceship in The Martian. In fact,the Orion looks more like the spacecraft that took us to the moon. However,according to their website ,“NASA’s Orion spacecraft is built to take humans farther than they’ve ever gone before."

           When asked if they will really be ready to go to Mars in the 2030sr Stu McClung,the manager of Mechanical,Pyrotechnic,Landing and Recover Systems,told us with confidence and pride,MMy capsule will be ready!” Although,he did make that statement with a bit of a wry smile(苦笑) .That is because he adfnits they still have a lot to figure out.

9. What does the underlined word “that” in Paragraph 1 refer to?

   A. The press conference.

   B. Taking humans to Mars.

   C. The release of The Martian.

   D. Speaking with NASA officials.

10. After interviewing some scientists,the author realized that.

   A. Aditya Sood had been lying

   B. making The Martian wasn't so difficult

   C. working with NASA employees was successful

   D. NASA employees really faced a lot of challenges

11. What does Jim Green think they can achieve by the 2030s?

   A. Helping humans land on Mars.

   B. Taking humans into Mars,orbit.

   C. Finding the landing spot on Mars.

   D. Learning about the neighborhood of Mars.

12. What do we know about the Orion?

   A. * It can be seen in The Martian.

   B. It once landed on the moon.

   C. It has an amazing look.

   D. It will land on Mars.
