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.

When introducing American universities, some of the first institutions to mention are the Ivy League schools. Originally, the Ivy League was an athletic conference made up of 8 private institutes of higher learning in northeastern United States. However, as time went on, these schools also became known for their excellence in academics besides athletics. Included in the Ivy League schools are Brown University, Columbia University, Cornell University, Dartmouth College, Princeton University, University of Pennsylvania, Yale University, and Harvard University. These 8 schools have been recognized as some of the best colleges and universities in the United States.
Harvard University is a private institution located in Cambridge, Massachusetts. The university includes a number of graduate and professional schools, as well as a college for undergraduates. In 2012, Harvard ranked number one in US News’ ranking of national universities again. Founded in 1636, Harvard is the oldest institute of higher education in the United States. It can be said that first there was Harvard, then the United States of America. Also, Harvard’s library contains the oldest collection of books in the United States as well as the largest private collection in the world. Harvard has also been described by Forbes Magazine as one of the “billionaire universities” as of their recent list of 469 billionaires, 50 received a degree from Harvard.
Harvard College (the institute for undergraduate students) is one of the most famous schools in the United States. It offers over 40 undergraduate fields of study, including astrophysics, mathematics, neurobiology(神经生物学), etc. And the financial aid program there is amazing. Even though the tuition is about 37,576, and there are other expenses throughout the year, about 70% of undergraduate students received financial aid. Out of those students, over 90% of them had their full need met. And the policies for international students are the same for U.S. citizens.
Harvard College is very selective, as it only admits about 6% of their applicants. For admission into Harvard College, it is required that students take the SAT or the ACT, as well as 2 SAT Subject Tests. Harvard will also look at other factors during admission such as your application essay, high school transcript, work experience, GPA (Grade Point Average), your interview, recommendations, and most importantly, your character and personal qualities.

I had been looking forward to my sister Patti’s visit for weeks. I had the whole thing planned. It would be one of our usual short-but-sweet get-togethers: a nice meal, some shopping, an outing with our kids.
When Patti arrived, lunch was cooking on the stove. Everything was perfect. Then, a few minutes later, a terrific clap of thunder rattled the window. A storm had sped in out of nowhere. The lights went out — for the next 12hours.
It seemed like a disaster. Our long-awaited plans! My homemade lunch! Seeing the unfinished pork, we had to eat cold food. We didn’t know what we can do next. The children asked, “Can we watch TV?” “The TV isn’t working.” I explained. So they begged, “Well, how about a video, then?” “How about computer games?” “Can’t you just microwave some popcorn?” I quickly realized just how much we all took electricity for granted.
But as the evening wore on, I also realized I had been taking something else for granted: the power of relationships. The point of my sister’s visit was not that we could go shopping. It didn’t matter whether we took our kids to the zoo. What counted were the people, not the plans.
We all sang old camp songs and put on shadow plays. After the kids eagerly went to bed with their own flashlights, Patti and I brought chairs onto my small front porch (门廊). At first we talked about our ruined plans. Then we sat back silently, listening to the rain dropping through the trees. I hadn’t sat out there in ages, and night air felt cool. We began to talk about our friends. We planned our parents’ upcoming anniversary party. Our conversation went to places it hadn’t gone in years.
I realized that what Patti and I had been looking forward to most was each other — something that often seemed vague on past short visits. Those get-togethers have always been enjoyable, but I must admit that they tend to melt together in my memory. That night the lights went out, on the other hand, they will burn brightly for a long time.

Since Henry Ford turned it into a mass-market product a century ago, the car has delivered many benefits. It has promoted economic growth, increased social mobility and given people a lot of fun. But the car has also brought many problems. It pollutes the air, creates traffic jams and kills people. An astonishing 1.24 million people die, and as many as 50 million are hurt, in road accidents each year.
Drivers and passengers waste around 90 billion hours in traffic jams each year. In some car-choked cities as much as a third of the petrol used is burned by people looking for a space to park.
Fortunately, a new technology promises to make motoring safer, less polluting and less tendency to hold-ups. “Connected cars”--which may eventually develop into driverless cars but for the foreseeable future will still have a human at the wheel-can communicate wirelessly with each other and with traffic-management systems, avoid walkers and other vehicles and find open parking spots.
Some parts of the transformation are already in place. Many new cars are already being fitted with equipment that lets them keep their distance and stay in a motorway automatically at a range of speeds. Soon, all new cars in Europe will have to be able to warn the emergency services if their on-board sensors(传感器) discover a crash. Singapore has led the way with using variable tolls(道路通行费) to smooth traffic flows during rush-hours; Britain is pioneering “smart motorways”, whose speed limits vary constantly to achieve a similar effect. Combined, these new inventions could create a much more highly effective system in which cars and their drivers are constantly warned of dangers and showed the ways, traffic always flows at the proper speed and vehicles can travel closer together, yet with less risk of crashing.
In the past, more people driving meant more roads, more jams, more death and more pollution. In future, the connected car could offer mankind the pleasures of the road with rather less of the pain.
According to Paragraph 2, the problem of parking has resulted in ______.

A．more time on the road

B．a great waste of fuel

C．even heavier traffic jams

D．increased death and injuries

What does “a similar effect” in the Paragraph 4 refer to?

D．Keeping steady traffic flows.

What is the author’s attitude towards connected cars?

A．Curious.	B．Doubtful.
C．Supportive.	D．Disappointed.

Which of the following can be the best title of the text?

A．The Future of Cars: Wireless Wheels

B．The Future Traffic Management System

C．The Benefits and Problems of Cars

D．The Promising Future of Car Production

I love sleeping. It’s something I’m good at. There’s nothing better than nodding off on the sofa in front of the TV and when my head hits the pillow at night, I have no problem falling into a deep sleep within minutes. There is one place where I never nap (打盹) and that’s at work--but new research suggests I should!
The idea of you and your colleagues heading off for a lie down in the afternoon may seem strange, but some companies such as Google and Facebook actually encourage it. Because it’s thought that a power-nap makes them more refreshed and more focused, and this in turn makes them more productive.
An Australian health writer called Victoria is a founder of a campaign called Nap Now which is trying to make sleeping at work more acceptable. She calls herself a “naptivist”! She says: “I think that our culture is a bit crazy not to accept it… It’s time to end the common work principle which is all about working longer and harder.”
So should we all be taking a sleeping bag and pillow to work with us? A few years ago, research by the East of England Development Agency found 30% of people have their best ideas in bed compared to just 11% who have them at their desk. That suggests people are more creative when they are relaxed--and the agency has called for companies to put beds in the workplace.
A nap in the afternoon is nothing new. In certain hot countries, such as Spain, a short rest or sleep in the afternoon-called a siesta-is perfectly normal. So maybe we should break from the traditional nine-to-five work culture and take up the siesta. The UK’s Sleep Council claims the nine-to-five working day does not fit into the natural sleeping pattern of the human race and says that bosses need to introduce a more sleep-friendly working day.
Why are the employees of Google allowed to nap in the workplace?

A．They are expected to work better.

B．They can’t focus their attention on the work.

C．They are running the Nap Now campaign.

D．They have difficulty in falling sleep at night.

The underlined word “naptivist” in Paragraph 3 probably refers to someone who ______.

A．takes no nap at work

B．enjoys napping at work

C．studies sleeping at work

D．fights against working long hours

According to the passage, what can we learn about siesta?

A．It is a newly practiced pattern.

B．It has been taken up in Finland.

C．It is sort of traditional work culture.

D．It fits into the natural sleeping pattern.

What is the author’s main purpose of writing the passage?

A．To explain how to nap at work.

B．To show how the new study was carried out.

C．To tell us the importance of sleeping at work.

D．To call for the more sleep-friendly work culture.
