If you are sending a text message, watching TV or listening to the radio, you may stop and give this your full attention. Multi-tasking shrinks(使……萎缩) the brain, research suggests.
A study found that men and women who frequently used several types of technology at the same time had less grey matter in a key part of the brain. University of Sussex researchers said, “Using mobile phones, laptops and other media devices simultaneously could be changing the structure of our brains.”
Worryingly, the part of the brain that shrinks is involved in processing emotion. The finding follows research which has linked multi-tasking with a shortened attention span, depression, anxiety and lower grades at school.
The researchers began by asking 75 healthy men and women how often they divided their attention between different types of technology. This could mean sending a text message while listening to music and checking email, or speaking on the phone while watching TV and surfing the internet. The volunteers were then given brain scans which showed they had less grey matter in a region called the anterior cingulated cortex (ACC)(前扣带皮质). Scientists have proved that brain structure can be changed on exposure to fresh environments and experience.
Other studies have shown that training – such as learning to play magic tricks or taxi drivers’ learning the map of London – can increase grey-matter densities(密度) in certain parts.
Experts have also warned of the harmful impact technology can have on our memory and attention span. The University of California team conducted a survey of more than 18,000 people aged between 18 and 99, and found 20% had problems with memory. Researchers were shocked greatly by the 14% of 18 to 39-year-old people who also worried about their memories.
Multi-tasking may shorten attention span, making it harder to focus and form memories, the researchers said, adding that youngsters may be particularly affected by stress.

Europe is now the biggest market for organic food in the world, having grown by 25 percent a year over the past 10 years. Denmark’s agriculture minister is herself an organic farmer. The UK market for organic food grew by 55 percent in 2000, while the food market as a whole grew by only one percent. Yet only seven percent of British shoppers account for nearly 60 percent of organic sales. However popular the idea of organic farming may be, it is still an interest for only a few people.
So what makes the idea of organic farming popular? Organic farming means farming with natural materials, rather than with man-made fertilizers or pesticides(杀虫剂). Organic farmers rely on many methods — such as crop rotation (农作物的轮作) and the use of resistant（有抵抗力的）varieties, because they are necessary for organic farmers to compensate for the shortage of man-made chemicals.
Organic farming is often supposed to be safer than traditional farming for the environment. Yet after a long research on organic farming worldwide for a number of years, science continues to be against this opinion. The House of Commons committee on agriculture stated that, even with complete research work, it would fail to find any scientific evidence to prove “that any of claims made for organic farming is always true”.
However, the talk about the benefits of organic farming is going on. This is partly because many people depend on their individual farm, the soil, the weather, and so on.The first paragraph mainly tells us _________.
| A．organic farming has been performed only in Europe over the past 10 years. |
| B．governments of European countries have cared less about organic farming. |
| C．organic farming isn’t so popular as expected. |
| D．European countries need organic food more than the other countries in the world. |
The underlined words “compensate for” in the second paragraph probably mean “_________”.
| A．argue for | B．care for |
| C．make up for | D．pay for |
What can we know about organic farming?
| A．It refers to farming with natural materials, instead of chemical fertilizers. |
| B．It refers to farming with chemical fertilizers rather than natural fertilizers. |
| C．It refers to farming with soil rather than any other thing. |
| D．It refers to growing crops with man-made fertilizers and pesticides. |
According to the third paragraph, _________.
| A．organic farming is safer than traditional farming for the environment. |
| B．the idea that organic farming is safer has not been proven by science. |
| C．organic farming is accepted by the UK’s House of Commons committee. |
| D．organic farming is preferred to traditional farming. |
Which of the following is TRUE, according to the passage?
| A．The UK’s agriculture minister is an organic farmer. |

A popular student in her small high school, Katie started college, expecting to do well in her courses and be best friends with her roommates. But things didn’t turn out that way. Psych 101, the course she thought would be a first-semester favorite, turned out to be a struggle.
Living away from home tends to be the toughest adjustment for first-year students. You may feel homesick in your first weeks or months. It can help to call, write, or email your parents and friends, making them know how you’re going. You can also talk with your roommates. As first-year students themselves, they’re probably experiencing many of the same fears and worries that you’re dealing with .
But what if you don’t get along well with your roommates?
In some cases, it can be a good thing if you and your roommates aren’t much alike. Different views on things may be helpful, so respect your differences no matter what.
If you and your roommates don’t get along well, it can help to find someone who you feel does understand you, which should be easy on a campus with so many people. Many schools have student organization nights where all of the campus clubs gather and promote their organizations, so you can meet people with the same interests there as you. You’ll also meet tons of people in class or in your dorm building.
As homesickness, painful throats, sprained (扭伤的) ankles and wisdom teeth that act up are common among college students, you should check out your student guidebook or your school’s website to find out information about the university health center.
If you think you cannot deal with your problems, make a stop at the school counseling (咨询)center. First-year troubles are something the counselors know well. You can get help there.From Paragraph 1 we can infer that __________.

We were standing at the top of a church tower. My father had brought me to this spot in a small town not far from our home in Rome. I wondered why.
“Look down, Elsa,” father said. I gathered all my courage and looked down. I saw the square in the center of the village. And I saw the crisscross (十字形) of twisting, turning streets leading to the square. “ See, my dear,” father said gently. “ There is more than one way to the square. Life is like that. If you can’t get to the place where you want to go by one road, try another.”
Now I understood why I was there. Earlier that day I had begged my mother to do something about the awful lunches that were served at school. But she refused because she could not believe the lunches were as bad as I said.
When I turned to father for help, he didn’t say anything. Instead, he brought me to this high tower to give me a lesson. By the time we reached home, I had a plan.
At school the next day, I secretly poured my lunch soup into a bottle and brought it home. Then I asked our cook to serve it to mother at dinner. The plan worked perfectly. She swallowed one spoonful and sputtered（喷溅出） “ The cook must have gone mad！” Quickly I told her what I had done, and Mother stated firmly that she would take up the matter of lunches at school the next day!
In the years that followed, I often remembered the lesson father taught me. I began to work as a fashion designer two years ago. I wouldn’t stop working until I tried every possible means to my goal.
