If English means endless new words, difficult grammar and sometimes strange pronunciation, you are wrong. Haven’t you noticed that you have become smarter since you started to learn a language?
According to a new study by a British university, learning a second language can lead to an increase in your brain power. Researchers found that learning other languages changes grey matter((中枢神经系统的)灰白质). This is the area of the brain which processes(加工,处理) information. It is similar to the way that exercise builds muscles.
The study also found the effect is greater when the younger people learn a second language.
A team led by Dr Andrea Mechelli, from University College London, took a group of Britons who only spoke English. They were compared with a group of “early bilinguals ” who had learnt a second language before the age of five, as well as a number of later learners.
Scans showed that grey matter density(密度) in the brain was greater in bilinguals than in people without a second language. But the longer a person waited before mastering a new language, the smaller the difference.
“Our findings suggest that the structure of the brain is changed by the experience of learning a second language,” said the scientists.
It means that the change itself increases the ability to learn.
Professor Dylan Vaughan Jones of the University of Wales has researched the link between bilingualism and maths skills. “Having two languages gives you two windows on the world and makes the brain more flexible,” he said. “You are actually going beyond language and have a better understanding of different ideas.”
The findings were matched in a study of native Italian speakers who had learned English as a second language between the ages of 2 and 34. Reading, writing, and comprehension were all tested. The results showed that the younger they started to learn, the better. “Studying a language means you get an entrance to another world,” explained the scientists.The main subject talked about in this passage is ________.

The name might sound like that of a superhero, but Pooperman’s task is much more basic.
He, or she, is trying to shame the irresponsible dog owners of Lincoln into cleaning up behind their pets.
Pooperman sticks notes into dog waste that owners have failed to clean up, warning them not to do it again. The typed notes read, "Don’t leave it. You might be the one who steps in it the next time you walk this way."
While welcoming the purpose of the message, local government officers have rounded on Pooperman for producing even more rubbish.
They say they would prefer it if people told them when there was a problem rather than adding to the rubbish problem. The city of Lincoln government’s environmental officer, Tony Garner, said, "The public can help instead by observing dog owners to make sure they clean up after their pets, perhaps asking them to remove the waste if they try to leave it."
"If this doesn’t work we can take action — people can tell us who the owner is, give us a description of the owner and the dog, or simply tell us when and where they allow their dog to produce the waste."
"We can then focus our patrols(巡逻) and take action against irresponsible owners."
Sue Grace, a dog owner from Birchwood, Lincs, said, "I always clean up after my dog. It’s very irresponsible if you don’t."
"There’s nothing worse than stepping in dog waste or dragging your long lead through it, but I don’t know that putting notes on it is the answer."
"It’s good that the local government is fighting against dog waste, though it might take one or two prosecutions(起诉) to make any difference."What does Pooperman try to do?
A.To have irresponsible dog owners remove dog waste. |
B.To advise the local government to protect the environment. |
C.To praise responsible dog owners for protecting the environment. |
D.To remind the local government to deal with the dog waste problem. |
What does the underlined part "rounded on" in Paragraph 4 mean?
A.Punished. | B.Blamed. |
C.Laughed at. | D.Worried about. |
According to the environmental officer, the public can .
A.punish irresponsible dog owners when necessary |
B.report irresponsible dog owners to the police if possible |
C.force irresponsible dog owners to clean up dog waste in some way |
D.request irresponsible dog owners to clean up dog waste then and there |
The dog owner Sue Grace believes that .
A.the local dog owners are irresponsible |
B.Pooperman is responsible and doing an effective job |
C.the law may play a role in fighting against dog waste |
D.the local government’s fighting against dog waste is successful |

Let us begin by saying what does not cause our dreams. Our dreams do not come from "another world ". They are not messages from outside sources. They are not a look into the future, either.
All our dreams have something to do with our feelings, fears, longings, wishes, needs and memories. If a person is hungry, or tired, or cold, his dreams may include a feeling of this kind . If the covers on your body, such as a quilt or a blanket, have slipped off your bed, you may dream that you are sleeping on the ice or snow. The material for the dream you will have tonight is likely to come from the experience you have today.
So the subject of your dream usually comes from something that has an effect on you while you are sleeping (feeling of cold, discomfort, etc.) and it may also use your past experiences and the wishes and interests you have now. This is why children are likely to dream of fairies, older children of school examinations, hungry people of food, homesick soldiers of their families and prisoners of freedom.
To show you how this is happening while you are asleep and how your needs and wishes can all be joined together in a dream, here is the story of an experiment. A man was asleep and the back of his hand was rubbed with a piece of absorbed cotton. He would dream he was in hospital and his charming girlfriend was visiting him, sitting on the bed and feeling gently his hands.
There are some scientists who have made a special study of why we dream, what we dream and what those dreams mean. Their explanations of dreams, though a bit reasonable, are not accepted by everyone, but they offer an interesting approach to the problem. They believe that dreams are mostly expressions of wishes that do not come true. In other words, dreams are a way of having your wishes carried out.From the passage we know that our dreams .
A.are imagination of our daily life |
B.are man’s curious look into the future |
C.have nothing to do with our feelings |
D.are to some degree connected with our feelings |
Older children often dream of examinations probably because .
A.they are interested in exams |
B.they are often worried about their studies |
C.they hope for a better life |
D.they show much interest in their studies |
According to the writer, the explanations of dreams that some scientists made .
A.are considered interesting, but unreasonable |
B.give a good answer to the question why we dream |
C.have some value, though not fully convincing |
D.have been proved by the findings of their studies |
Which of the following is the best title for this passage?
A.Why People Dream? | B.New Findings about Dreams |
C.Dream Makes Hopes | D.What Dreams Mean? |
People in several American states may be surprised to see cars on city streets without a driver.Experimental driverless vehicles now are legal in Florida,Nevada and California.They are pointing the way to a future that is not far down the road.The high-tech company Google has a number of self-driving cars,which had covered 480,000 kilometers by August.Volvo is among the companies doing road tests and says it plans to sell driverless cars by 2020.
In September,California Governor Jerry Brown signed an act to allow autonomous vehicles on the roads of his state."Today we're looking at science fiction becoming tomorrow's reality—the driverless car."The technology for these cars includes cameras,radar and motion sensors.The systems have been improved through competitions sponsored by the U.S.government agency DARPA.Engineer Richard Mason of the Rand Corporation helped design driverless vehicles for DARPA challenge races.
Cars have become much more fuel-efficient,and new electronic features are making Hondas safer,said Angie Nucci of Honda America."A camera on the passenger-side mirror actually engaged on your guiding screen so you can safely change lanes." Other safety features include warning systems on the front and the sides of the cars.These systems help drivers,but don't replace them.Curator Leslie Kendall of the Petersen Automotive Museum said autonomous cars will make the high ways safer.
"By taking out drivers,you also remove most risks of an accident," Kendall said.He said consumers,however,may be unwilling to lose control."It may take them time to come to realize that the technology is indeed reliable,but it will have to prove itself first."
Mason said the technology already works and the biggest challenge now is getting down the cost for driverless vehicles from hundreds of thousands of dollars to something more affordable.He said this will happen as the technology is improved.What can we learn from Paragraph l?
A.Driverless vehicles are now legal in the whole USA.
B.Volvo will be the first to sell driverless cars.
C.Driverless cars are pointing us a faraway future.
D.Google's self-driving cars have covered a long distance.We learn that Governor of California Jerry Brown_________.
A.helped design self-driving cars |
B.supports self-driving cars on roads |
C.considers self-driving cars science fiction |
D.improved the self-driving car systems |
What is the role of the systems mentioned in Paragraph 3?
A.They can help people drive more safely. |
B.They can take the place of drivers now. |
C.They can make cars run without fuel. |
D.They can help cars run much faster. |
According to Richard Mason,what is the biggest challenge for driverless cars?
A.They are not allowed to run on the road. |
B.Their technical problems remain to be solved. |
C.They are now too expensive for consumers. |
D.They are more dangerous for people on the street. |
Students from Florida International University in Miami walked on water Thursday for a class assignment.To do it,they wore aquatic (水上的)shoes they designed and created.
Alex Quinones was the first to make it to the other side of a 175-foot lake on campus in record time—just over a minute.Quinones,who wore oversized boat-like shoes,also won last year and will receive $ 500.Students had to wear the aquatic shoes and make it across the lake in order to earn an “A” on the assignment for Architecture Professor Jaime Canaves,Materials and Methods Construction Class."It's traditional in a school of architecture to do boats out of cardboard for a boat race.I thought our students were a little bit more special than that," Canaves said." We decided to do the walk on water event to take it to the next level."
A total of 79 students competed in the race this year in 41 teams.Only 10 teams failed to cross the lake.Others who fell got back up and made it to the end.The race is open to all students and anyone in the community.The youngest person to ever participate was a 9-year-old girl who competed in place of her mother,while the oldest was a 67-year-old female.
A large crowd on campus joined Canaves as he cheered on the racers.He shouted encouraging words,but also laughed as some unsteadily made their way to the end.
"A part of this is for them to have more understanding of designing and make it work better," he said.It is also a lesson in life for the students.
“Anything,including walking on water,is possible,if you do the research,test it and go through the design process seriously.”For what purpose did the students take part in the race?
A.To go across the lake to school. |
B.To test their balance on the water. |
C.To pass Professor Canaves’ class. |
D.To win the prize money of $ 500. |
Which of the following is true about the race?
A.The students who fell into the water had to quit. |
B.More than 20 teams failed to cross the lake. |
C.The students kept silent when the other racers competed. |
D.The youngest competitor competed instead of her mother. |
According to Canaves,this race can help the students_________.
A.understand designing better |
B.achieve almost everything |
C.work together and unite as one |
D.walk on the surface of water |
What is the purpose of this passage?
A.To advertise a student' s program. |

My daughter and I collected the empty cans and bottles in our home this morning.We had 6 full garbage bags later so I knew we would be spending a bit more of time at the recycling center.When we got there,a man and his kids were also doing the morning recycling and were using two of the four machines to recycle their plastic and cans.Luckily,we were able to use the 2 remaining machines.
Of course,there were others that came,but when they saw the two families with garbage bags full of recycled things,they quickly left.However,one woman came in with just 5 cans and looked as if she was in a hurry.So I stopped what I was doing and let her in to recycle her cans.Of course,she was grateful,and it felt good to let her go ahead of me.But that was not the whole story.
My daughter and I continued to work through the bags,but the plastic recycling machine stopped working because it was full.My daughter was left with nothing to do.The other family was still using the other two plastic recycling machines,but it seemed that they were almost done.I just told my daughter we would have to wait until they were done.But the man of the other family came through with another act of kindness.He offered to let us go ahead of him.I was really surprised,because we had more than 5 bottles,but he didn’t seem to mind.I happily accepted it.
