Let’s face it: Teenagers spend hours texting, socializing on Facebook and playing video games.And it’s driving their parents nuts.
Sure, there are real dangers connected with all this screen time—everything from cyberbullying(网络欺凌) to couch-potato obesity.Not to mention driving while texting, and shortened attention spans(持续时间).
Douglas Gentile, who studies the effects of media on children, says texting, Facebook and video games are not naturally bad.Nor are they naturally better or worse than watching TV, although they do lead to different risks, such as cyberbullying.
But research has shown that the more time kids spend in front of screens—whether it’s TV or instant-messaging—the worse their school performances are.“That doesn’t mean it’s true for every kid, but it makes sense, that for every hour a kid is playing video games, it’s an hour that they’re not doing homework or reading or exploring or creating,” he said.If screen time is taking the place of doing their homework, that’s bad.But if their homework is done, well, so what?
The study also found that the more time kids spend with media, the lower their grades and levels of personal satisfaction are.Gentile said the influence of screen time on school work can be reduced by what he calls “protective factors”.Those might include good teachers and a high-performing school, love of reading, coming from a family where education is valued.“If you had all these protective factors, then that one little risk factor, who cares?”
One thing parents should worry about is the way electronic devices encourage multitasking（多任务处理).
“As adults, your response speeds up, you’re quicker to look over your shoulder and notice little noises or lights.However this is not what the kids need when they get to the classroom.Scanning to see when the next message comes may not be good for kids.The more distractions(分心的事物) you have, the worse your performance is.” Getting kids to turn off their phones, iPods in order to let them concentrate（集中) on homework is a fight worth having.What statement may Gentile agree to?
| A．Kids get bad marks when using Facebook. |
| B．TV or texting affects kids equally. |
| C．Kids prefer video games to books. |
| D．Watching TV is better than playing video games. |
By saying “one little risk factor”, Gentile referred to ________
| A．love for reading | B．valuing education |
| C．screen time | D．good teachers |
It can be inferred from the last paragraph that________.
| A．kids can give quick answer to questions if texting |
| B．Multitasks aren’t really good for every kid |
| C．electric devices increase the attention of kids |
| D．kids perform well if doing many tasks together |
What might be the most suitable title for the passage?
| A．Are kids suffering cyber bullying on Facebook? |
| B．Are texting and Facebook worse for teens than TV? |
| C．Are kids willing to turn off their electric devices? |
| D．Are texting causing kids to lose interest in reading? |
If you think 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. 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 earlier people learn a second language, the greater the effect is.
A team led by Dr. Andrea Mechelli, from University College London(UCL), took a group of Britons who only spoke English. They were compared with a group of“early bilinguals(通两种语言的人)”, 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 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 was.
“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 earlier they started to learn, the better.“Studying a language means you get an entrance to another world,”explained the scientists.What does the underlined part“grey matter”(in paragraph 2) refer to?
| A．Grey hair. | B．Material of the brain. |
| C．Intelligence. | D．Difficult situations. |
The experience of learning a second language can .
| A．change one’s brain completely |
| B．improve one’s maths skills |
| C．make one smarter than others |
| D．increase the ability to learn |
We can learn from the passage that .
| A．the researchers from UCL did another study in Italy |
| B．a similar study was done on native Italian speakers who learn English as a second language |
| C．the research done on the Italians showed a totally different result |
| D．it will be easier for one to travel around the world by learning a second language |
What’s the main idea of the passage?
| A．Learning a second language can help improve your brain power. |
| B．You should learn a second language in English that is not your native language. |
| C．If you want to learn a second language, you should do it at a certain age. |
| D．The research done by the researchers from UCL is very successful. |

William Herschel was born on November 15th, 1738 in Hanover in a family of musicians. In 1757,he fled to England and began earning a living as an organist and later composer and conductor. In 1772, he convinced his sister Caroline to join him as a singer. In their spare time the brother-sister team became occupied in astronomy. William died at his home in Slough, near Windsor on August 25th,1822,and Caroline on September 1st,1848.
Herschel’s first major discoveries were to show that Mars and Jupiter exhibit axial rotation(绕轴自转). Herschel struck fame in 1781,when on March 13th he discovered the planet Uranus(天王星) while engaged in work aimed at determining stellar parallax(恒星视差).This being the first new planet discovered since ancient times, Herschel, until then a mere amateur astronomer relatively unknown even in England, became world-famous. Adopting a historically proven strategy, Herschel named the new planet Georgium Sidum,in honor of the then ruling English king GeorgeⅢ. The trick worked once again, as King GeorgeⅢ gave William and Caroline the titles of“The King’s Astronomer”and“Assistant to the King’s Astronomer”, an honor which came with a life’s pension for both. In 1782 they moved to Bath, and shortly thereafter to Slough, and from this point on William and Caroline could devote themselves entirely to astronomy. The Herschels went on to discover two moons of Uranus in 1787.
While Caroline became increasingly occupied with the search for comets at which she was quite successful, William became for a time interested in the Sun. Inspired by Wilson’s 1774 work, he put forth the theory of sunspots(太阳黑子),an opinion that continued to exist well into the nineteenth century. In 1800,he became interested in the solar spectrum(太阳光谱),and uncovered the first evidence for solar energy output outside of the visible spectrum, in what is now known as the infrared(红外线).In 1801, he published two papers that effectively started the field of solar influences on Earth’s weather.Herschel made himself known to the world mainly by .
| A．discovering the planet Uranus |
| B．determining stellar parallax |
| C．discovering two moons of Uranus |

| C．was interested in astronomy |
| D．gave Herschel a lot of useful suggestions |
What do we know about Caroline from the passage?
| A．She was successful in music. |
| B．She was given the title of“The King’s Astronomer”. |
| C．She died later than her brother. |
| D．She published two papers. |
This passage mainly tells readers .

He’s an old cobbler(修鞋匠) with a shop in the Marais, a historic area in Paris. When I took him my shoes, he at first told me,“I haven’t time. Take them to the other fellow on the main street. He’ll fix them for you right away.”
But I had my eyes on his shop for a long time. Just looking at his bench loaded with tools and pieces of leather, I knew he was a skilled craftsman(手艺人).“No.”I replied,“The other fellow can’t do it well.”
“The other fellow”was one of those shopkeepers who fix shoes and make keys —without knowing much about mending shoes or making keys. They work carelessly, and when they have finished sewing back a sandal strap(鞋带), you might as well just throw away the pair.
My man saw I wouldn’t give in, and he smiled. He wiped hands on his blue apron(围裙),looked at my shoes, had me write my name on one shoe with a piece of chalk and said,“Come back in a week.”
I was about to leave when he took a pair of soft leather boots off a shelf.
“See what I can do?”he said with pride.“Only three of us in Paris can do this kind of work.”
When I got back out into the street, the world seemed brand-new to me. He was something out of an ancient legend, this old craftsman with his way of speaking familiarly, his very strange dusty felt hat, his funny accent and his pride in his craft.
These are times when nothing is important but the bottom line, when you can do things any old way as long as it“pays”,when, in short, people look on work as a path to ever-increasing consumption rather than a way to realize their abilities. In such a period it is a rare comfort to find a cobbler who gets his greatest satisfaction from pride in a job well done.Which of the following is true about the old cobbler?
| A．He was equipped with the best repairing tools. |
| B．He was the only cobbler in the Marais. |
| C．He was proud of his skills. |
| D．He was a native Parisian. |
The sentence“He was something out of an ancient legend.(Paragraph 7) implies that .”
| A．nowadays you can hardly find anyone like him |
| B．it was difficult to communicate with this man |
| C．the man was very strange |
| D．the man was too old |
According to the author, many people work just to .
| A．realize their abilities | B．gain happiness |
| C．make money | D．gain respect |
This story wants to tell us that .
| A．craftsmen make a lot of money | B．whatever you do, do it well |
| C．craftsmen need self-respect | D．people are born equal |
Did you know that there are actually people who have paid for a flight to the moon? In the future, there will be a lot more opportunities to travel to faraway places than now… perhaps even as far as the moon. As people adventure further and further away and as planes, trains, cars, and rocket ships become faster, is it safer to have these vehicles controlled by humans or by computers?
While many flights by plane are controlled automatically by machines, most people today wouldn’t let their car drive itself. That’s because currently the autopilot function on your car can only keep it on the same course you are travelling on. It won’t turn the car right or left. It won’t stop if an animal jumps in the way. However, cars today can sense when something is too close and warn the driver with flashing lights and alarms. Many cars also have GPS（global positioning systems） that tell drivers which road to take and when to turn. These systems, unlike human drivers, never get lost. In the future, it is easy to believe that your car will be better able to drive itself with the aid of computers that can determine the position of your car and the speed it should travel at.
In addition to computers being ‘smarter’ than people regarding the best way to go or knowing how close another vehicle is, computers don’t get sick, tired, or angry. This means they won’t make the same mistakes that people make when they are not having a good day. While responding with emotion is a good thing when choosing the best way to deal with a friend’s personal problem, it may not be such a good thing when deciding what to do at the wheel of a fast-moving vehicle.
So what are the disadvantages of autopilot systems? Maybe one disadvantage is that a small computer problem could cause a serious accident. It could also be argued that in unexpected situations, computers might not be able to respond appropriately; some decisions require human emotions. Another problem might be that if everything were controlled by computers or robots, people wouldn’t have any jobs. What is the best title for the passage?
| A．The Development of Autopilot |
| B．Technology of Future Travel |
| C．A New Driving System |
| D．Computerized Cars |
Which of the following is the disadvantage of an autopilot system?
| A． It won’t make the same mistakes as people do. |
| B． It can point out the best route for the driver. |
| C． It might not respond properly to unexpected situations. |
| D．It does not have human emotions to influence its function. |
If some falling rocks roll down toward your car, the autopilot on your car will_______.
| A．inform you of the danger |
| B．turn the car right or left |
| C．do nothing about it |
| D．stop the car |
What’s the author’s attitude towards the autopilot?
| A．Approving. | B．Objective. | C．Negative. | D．Doubtful. |
