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.

1.The underlined word "simultaneously" in Para.2 means _________.

A. on one’s own　　　　　 B. at no time

C. at the same time　　　　 D. by accident

2. All of the following are possible effects of multi-tasking except _________.

A. saving time

B. a shortened attention span

C. lower grades at school

D. depression and anxiety

3.What can increase grey-matter densities?

A. Sending a text message while listening to music .

B. Students’ doing their homework.

C. Taxi drivers’ learning the map of London.

D. Speaking on the phone while watching TV.

4.Which of the following can be the best title of this passage?

A. Media multi-tasking is becoming more popular.

B. Multi-tasking shrinks the brain.

C. Multi-tasking may shorten attention span.

D. People are worried about their memories.

Compassion and love are concepts that are often thought to be felt by humans only. As the most intelligent creatures to ever walk the earth, we tend to assume that we are the only ones who can feel emotions. We forget that the speechless beings who live here with us - animals - also have the same capability.

During a cold night in Ontario, Canada, a passer-by spotted something on the side of the road that made her stop -a shaking dog curled up in the snow.

When she approached the pup, she discovered that she wasn’t alone-she was cuddling five orphaned black kittens to keep them warm.

The dog surely could have found a safer place to stay for the night, but she chose instead to help not just herself but other stray animals as well.

The Good Samaritan called Pet and Wildlife Rescue and an animal control officer picked them up. When they got to the shelter, it was apparent that a close bond had already been formed between the dog and the orphaned kittens. The staff decided to name the kind dog Serenity in honor of her selfless act.

“It’s truly heartwarming!” a shelter spokesperson told The Dodo. “It had been a very cold night so these kittens would have had a very hard time surviving.”

Aside from requiring treatment for worm and flea infections, the orphaned kittens are now safe. Just like a proud and doting mother, Serenity insisted on checking on her babies regularly to oversee their progress.

The good news is that the kittens are now living with a foster family who will care for them until they are old enough to be adopted. Serenity, on the other hand, is still looking for a family.

According to the shelter, she loves zooming around in the yard and is big on playing. She is also quite jumpy, so she would do best in a home without small children.

1.What did the passer-by see on the road?

A.A dog curled up in the snow.

B.Five kittens were in the snow alone.

C.A dog was warming five kittens in the snow.

D.A dog found a safe place to stay for the night.

2.What does the underlined word “she” in paragraph 3 refer to?

A.The passer-by. B.The dog.

C.The kitten. D.The spokesperson.

3.Where is the dog Serenity now?

A.Living in the shelter. B.Being adopted by a family.

C.Staying with the kittens. D.Playing with some children.

4.What can we draw from the story?

A.Animals and humans should live in harmony.

B.A sad end can be turned into a positive one.

C.Animals have the same capability with humans.

D.Animals can feel compassion and love like humans.

高三英语单项填空简单题查看答案及解析

D

In China, some radio broadcasting stations use hotlines to encourage listeners to take part in the talk shows.

That is a good idea. Yes, the fact is that some people do nothing but break the whole programme.

Some people know little about the topic under discussion. Sometimes they do not even know what the host is talking about. So the host has to tell the caller what the show is about. Usually the caller will ask a few questions which express his hope and show his ignorance(无知). Then the host has to answer and explain ---how silly it is! It wastes a lot of time.

It seems that some people phone the hotlines for fun. They just want to let the listeners hear them. They do not care what the topic is, whether they themselves are interested in the topic or how silly they appear to be.

It is necessary for radio stations to improve the hotline programmes. In my opinion, if a caller does not know what is going on, the operator should not let the caller take part in it.

47. The underlined sentence “some people do nothing but break the whole programme” may tell us that _____

A. radio stations use hotlines in a wrong way

B. there are problems to solve in the use of hotlines by some radio broadcasting stations

C. the use of hotlines by some radio broadcasting stations is a good idea

D. some people have unclear thoughts

48. The underlined word“operator” in the last paragraph refers to_____

A. 话务员        B. 听众        C. 医生         D. 主持人
