If English means endless new words,difficult gramrnar 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.This is the area of the brain which processes information.It is similar to the way that exercise builds muscles.
The study also found the effect is greater,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 goup 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.

Global warming is when the earth heats up,the temperature rises.It happens when greenhouse gases—carbon dioxide,water vapor,nitrous oxide(二氧化氮),and methane(沼氣) trap heat and light from the sun in the earth’s atmosphere,which increases the temperature.This is like when heat is trapped in a car.On a very hot day,the car gets hotter when it is out in the parking lot.This is because the heat and light from the sun can get into the car,by going through the windows,but it can’t get back out.Once the light is inside the car,it is trapped and the heat builds up,just like it does in the earth’s atmosphere.This is what the greenhouse effect does to the earth.The heat and light can get through the atmosphere,but it can’t get out.As a result,the temperature rises.
Sometimes the temperature can change in a way that helps us.The greenhouse effect makes the earth appropriate for people to live on.Without it,the earth would be freezing,or on the other hand it would be burning hot.We would not get the sun’s heat and light to make the night somewhat warm.During the day,especially during the summer,it would be burning because the sun would be up with no atmosphere to filter(過(guò)濾) it,so people,plants,and animals would be exposed to all the light and heat.
Although the greenhouse effect makes the earth able to have people living on it,if there gets to be too many gases,the earth can get unusually warmer,and many plants,animals,and people will die.They would die because there would be less food (plants like corn,wheat,and other vegetables and fruits).This would happen because the plants would not be able to take in the heat.This would cause us to have less food to eat,but it would also limit the food that animals have.Gradually,people,plants,and animals would all die of hunger.
People are doing many things to try to stop global warming.One thing people are doing is carpooling.Carpooling is driving with someone to a place that you are both going to.This minimizes the amount of greenhouse gases put into the air by a car.
Another thing that people are doing is being more careful about leaving things turned on like the television,computer,and the lights.A lot of people are taking time away from the television,and instead,they are spending more time outdoors.This helps our planet out a lot.Now,more people are even riding buses,walking to school,and riding their bikes to lower the amount of greenhouse gases in the air.
Planting trees and recycling also help.If you recycle,less trash goes to the dump,and less trash gets burned.As a result,there are fewer greenhouse gases in our atmosphere.Although adults do many things to help stop global warming,kids can do just as much.
小題1:By the example given in Paragraph 1,the author wants to ________.
A.explain how greenhouse gases work
B.show his feeling in a car in hot summer
C.tell us cars are causes of greenhouse gases
D.say that there are greenhouse gases in every car
小題2:The underlined word “it” in Paragraph 2 refers to “________”.
A.lightB.heat
C.temperatureD.greenhouse effect
小題3:What is the main idea of Paragraph 3?
A.If there is greenhouse effect,all the plants will die.
B.Human beings are likely to disappear from the earth.
C.Crops can’t take the heat if there is greenhouse effect.
D.Although greenhouse effect is necessary,too much of it causes us to die.
小題4:What will the author most probably discuss in the paragraph that follows?
A.Why cars and buses pollute the air a lot.
B.What kids can do to help stop global warming.
C.What global warming is doing to the environment.
D.Who should be responsible for the environmental problems.

  Ten years ago, with only about 1, 000 pandas left in the world, China was desperately trying to clone(克隆)the animal and save the endangered species(物種). That was a move similar to what Texas A & M University researchers had been undertaking for the past five years in a project called “Noah’s Ark”(諾亞方舟).
Noah’s Ark was aimed at collecting eggs, embryos(胚胎), semen and DNA of endangered animals and storing them in liquid nitrogen. If certain species should become extinct, Dr. Duane Kraemer, a professor in Texas A & M’s College of Veterinary Medicine, said there would be enough of the basic building blocks to reintroduce the species in the future.

It was estimated that as many as 2, 000 species of mammals, birds reptiles would become extinct in over 100 years. The panda, native only to China, was in danger of becoming extinct in the next 25 years.
This week, Chinese scientists said they grew an embryo by introducing cells from a dead female panda into the egg cells of a Japanese white rabbit. They were then trying to implant the embryo into a host animal.
The entire procedure could take from three to five years to complete.
“The nucleus transfer(核子移植)of one species to another is not easy, and the lack of available(capable of being used)panda eggs could be a major problem,”Kraemer believed. “They will probably have to do several hundred transfers to result in one pregnancy(having a baby). It takes a long time and it’s difficult, but this could be groundbreaking science if it works. They are certainly not putting any live pandas at risk, so it is worth the effort, ”added Kraemer, who was one of the leaders of the project at Texas A& M, the first-ever attempt at cloning a dog.
“They are trying to do something that’s never been done, and this is very similar to our work in Noah’s Ark. We’re both trying to save animals that face extinction. I certainly appreciate their effort and there’s a lot we can learn from what they are attempting to do. It’s a research that is very much needed. ”
At present, the project has worked. The number of the pandas has increased to more than 1, 500.
小題1:The aim of “Noah’s Ark” project was to    .
A.make efforts to clone the endangered pandas
B.save endangered animals from dying out
C.collect DNA of endangered animals to study
D.transfer the nucleus of one animal to another
小題2: According to Professor Kraemer, the major problem in cloning pandas would be the lack of    .
A.a(chǎn)vailable panda eggs   B.host animals
C.qualified researchersD.enough money
小題3: The best title for the passage may be    .
A.China’s Success in Pandas Cloning
B.The First Cloned Panda in the World
C.Exploring the Possibility to Clone Pandas
D.China—the Native Place of Pandas Forever
小題4:From the passage we know that    .
A.Kraemer and his team had succeeded in cloning a dog
B.scientists tried to implant a panda’s egg into a rabbit
C.Kraemer would work with Chinese scientists in clone researches
D.a(chǎn)bout two thousand species would probably die out in a century

科目:高中英語(yǔ) 來(lái)源:不詳 題型:閱讀理解

During her junior year of high school, Diane Ray's teacher handed her a worksheet and instructed the 17-year-old to map out her future financial life. Ray pretended to buy a car, rent an apartment, and apply for a credit card.  Then, she and her classmates played the "stock market game", investing(投資) the hypothetical(虛擬的) earnings from their hypothetical jobs in the market in the disastrous fall of 2008. "Our pretend investments crashed," Ray says, still frightened. "We got to know how it felt to lose money."
That pain of earning and losing money is a feeling that public schools increasingly want to teach. Forty states now offer some type of financial instruction at the high-school level, teaching students how to balance checkbooks and buy stock in math and social-studies classes. Though it's too early to measure the full influence of the Great Recession(大蕭條), the interest in personal-finance classes has risen since 2007 when bank failures started to occur regularly. Now, many states including Missouri, Utah, and Tennessee require teenagers to take financial classes to graduate from high school. School districts such as Chicago are encouraging money-management classes for kids as young as primary school, and about 300 colleges or universities now offer online personal-finance classes for incoming students. "These classes really say, 'This is how you live independently,' " says Ted Beck, president of National Endowment for Financial Education.
Rather than teach investment methods or financial skills, these courses offer a back-to-the-basics approach to handling money: Don't spend what you don't have. Put part of your monthly salary into a savings account, and invest in the stock market for the long-term rather than short-term gains. For Ray, this means dividing her earnings from her part-time job at a fast-food restaurant into separate envelopes for paying bills, spending and saving.  "Money is so hard to make but so easy to spend," she says one weekday after school. "That is the big takeaway."
Teaching kids about the value of cash certainly is one of the programs' goals, but teachers also want students to think hard about their finances long term. It's easy for teenagers to get annoyed about gas prices because many of them drive cars. But the hard part is urging them to put off the instant satisfaction of buying a new T-shirt or an iPod. "Investing and retirement aren't things teenagers are thinking about. For them, the future is this weekend," says Gayle Whitefield, a business and marketing teacher at Uth’s Riverton High School.
That’s a big goal for these classes: preventing kids from making the same financial missteps their parents did when it comes to saving, spending, and debt. Though the personal savings rate has increased up to 4. 2 percent, that’s still a far distance from 1982, when Americans saved 11. 2 percent of their incomes. “It’s hard for schools to reach strict money-management skills when teenagers go home and watch their parents increase credit-card debt. It’s like telling your kids not to smoke and then lighting up a cigarette in front of them,” Beck says.
Even with these challenges, students such as Ray say learning about money in school is worthwhile. After Ray finished her financial class, she opened up a savings account at her local bank and started to think more about how she and her family would pay for college. “She just has a better understanding of money and how it affects the world,” says her mother, Darleen-and that’s sown to the details of how money is spent from daily expenses to various taxes. All of this talk of money can make Ray worry, she says, but luckily, she feels prepared to face it.
小題1:The “stock market game” mentioned in Paragraph 1 is meant to       .
A.introduce a new course to students
B.help students learn about investment
C.teach how to apply for a credit card
D.encourage students’ personal savings

A.better students’ learning methods

C.help students get accepted by colleges
D.make students become very wealthy

A.pay off all her debts. B.handle her money better

There are some things humans can go without. We can lose a kidney (腎)or a lung, an arm or two and still live perfectly well. But some fish put us to shame. They can get by without stomachs.

One such fish is the stout longtom(尖嘴魚(yú) ). The group it belongs to carries a more appropriate name: the needlefish. All needlefish lack stomachs. Their ancestors had them, but later they were lost.
The stout longtom can reach 1.3 meters in length, and lives near the sea surface. Like all needlefish, it can jump out of the water to escape its enemies. Tropical(熱帶) fishermen are sometimes injured by needlefish. In 1977, a 10-year-old Hawaiian boy was killed when a needlefish jumped through his brain. The longtom eats smaller fish. Its teeth are not good at cutting fish into pieces, so it swallows fish whole.
Ryan Day from Australia and his colleagues wanted to know how the longtom digests its meaty meals without a stomach, so they ran some chemical tests about the fish.
Day’s results show that the longtom can consume food without the help of a stomach. It uses a special material called trypsin(胰島素) that can break down proteins without acid — although the approach is less efficient than using a stomach.
Because it’s a meat-eating animal, the longtom gets a lot of protein in its food, so it can afford this slightly less efficient system for absorbing it. Two plant-eating fish that Day studies actually had higher levels of trypsin in their body, as their food was low in protein.
Day thinks that the longtom and its stomachless relatives might actually have arrived at an energy-saving solution. He says that although the stomach is critical to many kinds of animal, the organ is “a fairly expensive organ to run”. This perhaps explains why some animals have got rid of theirs.
小題1:What does the underlined phrase “get by” mean?
A.Live.B.Fight.C.Hunt.D.Recover.
小題2:Ryan Day ran the chemical tests in order to find out how the longtom ______.
A.catches smaller fish in the water
B.can jump so high to escape its enemies
C.digests the smaller fish in its body
D.uses acid to break down the protein
小題3:What plays a key role in the longtom’s digestion process?
A.AcidB.Trypsin.C.The stomach.D.Protein in its body.
小題4:Ryan Day’s results show that ______.
A.the longtom often waste energy
B.the longtom can make acid easily
C.the longtom’s high-protein food helps its unique way of consuming food.
D.meat-eating fish have higher levels of trypsin in their bodies than plant-eating fish
