                             A

             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(龙虾) 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.

            In 2014 and 2015,a Gallup World Poll surveyed people m 119 countries. A group of scientists analyzed how people answered two of the questions: How much do you know about global warming,and how serious was it to you and your family? And they were surprised.

            Most scientists think the world's  climate changing fast,yet many people do not share the scientists,view.What's  more,how people responded depended on various reasons. These included where people livd,how;many years they'd  gone to school,how much money they earned,their gender — even things such as how polluted the air was in the place where they lived. It's the first time those have been studied for their possible link to people' s thoughts on climate change.

            Many people were not even aware of global warming. Most people in Africa and the Middle East had!never heard of the concept. In contrast,people in the wealthier and more highly educated nations were quite familiar with global warming. Among people who were : aware of global warming,those in the poorer nations i tended to judge it as a far bigger threat. And in Latin Amenca and Europe people were more likely to see global warming as a bigger menace (威胁) when they understood the role that humans have played in that : warming. In Africa people were more likely to see :

climate change as a risk if it was tied to local temperatures or air pollution.

          “To our knowledge,this is the first and only truly global study,”according to the study's  lead author Lee.; Lee says the new analysis indicates that there's  still much work to do to get the word out about global warming. Indeed,helping people in different parts of the globe  understand it may require explaining the data and risks in;very different ways. Those explanations might have to differ from one neighboring country to another.

          When Lydia Nash appeared on the TV programme Who wants to be a millionaire? and was fortunate enough to win £16,000,she decided to give all the money away. This wouldn't  have been surprising if she had been rich or famous,but Lydia is a 19-year-old student.

          Lydia gave all the money to a charity which helps orphans in Thailand. ul first visited the orphanage when I was seventeen,and I felt very depressed by what I saw. When I got back to England I felt angry — looking around all I could see were people who were obsessed with money. That persuaded me to return to Thailand the following year."

          After she donated the money some of her friends thought that she had made the wrong decision. “Some people said I should have saved it for a deposit,” Lydia said. aStudents always complain about being poor. But there's  an enormous difference between us and people who have absolutely no money."

          With the help of the money Lydia gave them,the charity has just finished building “Rainbow House”,a new facility that will house 50 young children.

          If Lydia had won a million pounds and not only £16,000,would she still have given away all the money? She said, “Before going on the show I thought a lot about what it would be like to have a lot of money and I realized that I wouldn't  like it at all. And as I had been to the orphanage and had seen all the work that needed to be done,I knew how useful that money could be. I definitely think I got more enjoyment from giving the money away than if I had kept it for myself."

   B. She isn’t very famous.

   C. She is young and not very wealthy.

          Feel too old or too stupid to learn a second :

language? It may be worth peraeven(坚持).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(老年痴呆) who are fluent in two languages exhibit symptoms of the condition four or five years later than people who are(只用一种语言的) .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 (认知的)           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.

   A. may decrease while ageing

   B. can change with learners’ IQ

   A. By studying Scottish history.

   B. By watching participants’ behavior.

   C. By comparing participants’ test scores.

   D. By analyzing participants’ questionnaires.

11. What can we leam about Thomas Bak's study?
