Multitasking
People who multitask all the time may be the worst at doing two things at once, a new research suggests. The findings, based on performances and self-evaluation by about 275 college students, indicate that many people multitask not out of a desire to increase productivity, but because they are easily distracted (分心) and can’t focus on one activity. And “those people turn out to be the worst at handling different things,” said David Sanbonmatsu, a psychologist at the University of Utah.
Sanbonmatsu and his colleagues gave the students a set of tests and asked them to report how often they multitasked, how good they thought they were at it, and how sensation-seeking (寻求刺激) or imperative (冲动) they were. They then evaluated the participants’ multitasking ability with a tricky mental task that required the students to do simple mathematical calculations while remembering a set of letters.
Not surprisingly, the scientists said, most people thought they were better than average at multitasking, and those who thought they were better at it were more likely to report using a cellphone while driving or viewing multiple kinds of media at once. But those who frequently deal with many things at the same time were found to perform the worst at the actual multitasking test. They also were more likely to admit to sensation-seeking and impulsive behavior, which connects with how easily people get bored and distracted.
“People multitask not because it’s going to lead to greater productivity, but because they’re distractible, and they get sucked into things that are not as important.” Sanbonmatsu said.
Adam Gazzaley, a researcher at the University of California, San Francisco, who was not a member of the research group, said one limitation of the study was that it couldn’t find out whether people who start out less focused toward multitasking or whether people’s recognizing and understanding abilities change as a result of multitasking.
The findings do suggest, however, why the sensation-seeker who multitask the most may enjoy risky distracted driving. “People who are multitasking are generally less sensitive to risky situations.” said Paul Atchley, another researcher not in the group. “This may partly explain why people go in for these situations even though they’re dangerous.” The research led by Sanbonmatsu indicates that people who multitask .
| A．seek high productivity constantly |
| B．prefer handling different things when getting bored |
| C．are more focused when doing many things at a time |
| D．have the poorest results in doing various things at the same time |
When Sanbonmatsu and his colleagues conducted their research, they .
| A．assessed the multitasking ability of the students |
| B．evaluated the academic achievements of the students |
| C．analyzed the effects of the participants’ tricky mental tasks |
| D．measured the changes of the students’ understanding ability |
According to Sanbonmatsu, people multitask because of their _.
| A．limited power in calculation | B．interests in doing things differently |
| C．inability to concentrate on one task | D．impulsive desire to try new things |
From the last paragraph, we can learn that multitaskers usually____ .
| A．drive very skillfully |
| B．go in for different tasks |
| C．fail to react quickly to potential dangers |
| D．refuse to explain the reasons for their behavior |
Mandara seemed to know something big was about to happen. So she let out a yell, caught hold of her 2-year-old daughter Kibibi and climbed up into a tree. She lives at the National Zoo in Washington, D.C.
And on Tuesday, August 23rd, witnesses say she seemed to sense the big earthquake that shook much of the East Coast before any humans knew what was going on. And she’s not the only one. In the moments before the quake, an orangutan (猩猩) let out a loud call and then climbed to the top of her shelter.
“It’s very different from their normal call,” said Brandie Smith, the zookeeper. “The lemurs (monkey-like animals of Madagascar) will sound an alarm call if they see or hear something highly unusual.”
But you can’t see or hear an earthquake 15 minutes before it happens, can you? Maybe you can — if you’re an animal. “Animals can hear above and below our range of hearing,” said Brandie Smith. “That’s part of their special abilities. They’re more sensitive to the environment, which is how they survive.”
Primates weren’t the only animals that seemed to sense the quake before it happened. One of the elephants made a warning sound. And a huge lizard (蜥蜴) ran quickly for cover. The flamingoes (a kind of bird) gathered before the quake and stayed together until the shaking stopped.
So what kind of vibrations were the animals picking up in the moments before the quake? Scientist Susan Hough says earthquakes produce two types of waves — a weak “P” wave and then a much stronger “S” wave. The “P” stands for “primary”. And the “S” stands for “secondary”. She said she thinks the “P” wave might be what set the animals off.
Not all the animals behaved unusually before the quake. For example, Smith says the zoo’s giant pandas didn’t jump up until the shaking actually began. But many of the other animals seemed to know something was coming before it happened. “I’m not surprised at all,” Smith said.Why did Mandara act strangely one day?
| A．Because it sensed something unusual would happen. |
| B．Because its daughter Kibibi was injured. |
| C．Because it heard an orangutan let out a loud call. |
| D．Because an earthquake had happened. |
According to Brandie Smith, _____.
| A．many animals’ hearing is sharp |
| B．earthquakes produce two types of waves |
| C．primates usually gather together before a quake |
| D．humans can also develop the ability to sense a quake |

What is the best title for the passage?
| A．How animals survive a quake. | B．How animals differ from humans. |

A 34-year-old mother has spoken of how she woke up thinking she was 15 years old and living in 1992.
Naomi Jacobs, from Manchester, was convinced she was still a teenager. In her mind, John Major was Prime Minister and George Bush Sr. was running the White House. She also showed how she screamed when a boy appeared and called her “Mum”. Mobile phones and e-mails were puzzling and Google, Facebook and YouTube sounded like made-up words, she said.
Ms. Jacobs, who had no memory of the years, was told by doctors that she had Transient Global Amnesia (TGA). She has now written a book about the experience which happened in 2008.
“I fell asleep in 1992 as a brave, very confident know-it-all-15-year-old, and woke up as a 32-year-old single mum living in a rented house,” Ms. Jacobs said. “The last thing I remember was falling asleep in my bed, dreaming about a boy in my class. When I woke up, I looked in the mirror and had the fright of my life when I saw an old woman with wrinkles staring back at me. Then a little boy appeared and started calling me Mum. That’s when I started to scream. I didn’t know who he was. I didn’t think he was much younger than I was, and I certainly didn’t remember giving birth to him. I began sobbing uncontrollably. I just wanted my mum. I couldn’t get my head around going to bed one night and waking up in a different century.”
TGA is a rare type of amnesia which can occur suddenly, affecting around three people per 100,000 each year. Fortunately, permanent memory loss is rare. Ms. Jacobs’ memory started to return after eight weeks.
Some people who often suffer from migraines (偏头痛) also appear to be more likely to have TGA. The cause of TGA is unknown. Some think that it may be caused by a temporary cut of blood flow to parts of the brain involved in memory.When a little boy came to call her “Mum”, Naomi Jacobs was _____.

America is a mobile society. Friendships between Americans can be close and real, yet disappear soon if situations change. Neither side feels hurt by this. Both may exchange Christmas greetings for a year or two, perhaps a few letters for a while — then no more. If the same two people meet again by chance, even years later, they pick up the friendship. This can be quite difficult for us Chinese to understand, because friendships between us develop more slowly but then may become lifelong feelings, extending (延伸) sometimes deeply into both families.
Americans are ready to receive us foreigners at their homes, share their holidays, and their home life. They will enjoy welcoming us and be pleased if we accept their hospitality (好客) easily.
Another difficult point for us Chinese to understand Americans is that although they treat us warmly in their personal everyday lives, they don’t show their politeness to us if it requires a great deal of time. This is usually the opposite of the custom in our country where we may be generous with our time. Sometimes, we, as hosts, will appear at airports even in the middle of the night to meet a friend. We may take days off to act as guides to our foreign friends. The Americans, however, express their welcome usually at homes, but truly can not manage the time to do a great deal with a visitor outside their daily routine. They will probably expect us to get ourselves from the airport to our own hotel by bus. And they expect that we will phone them from there. Once we arrive at their homes, the welcome will be full, warm and real. We will find ourselves treated hospitably.
For the Americans, it is often considered more friendly to invite a friend to their homes than to go to restaurants, except for purely business matters. So accept their hospitality at home! Which of the following statements is TRUE according to the passage?
| A．Friendships between Americans usually extend deeply into their families. |
| B．Friendships between Americans usually last for all their lives |
| C．Americans always show their warmth even if they are very busy. |
| D．Americans will continue their friendships again even after a long break. |
From the last two paragraphs we can learn that when we arrive in America to visit an American friend, we will probably be ______.
| A．warmly welcomed at the airport | B．offered a ride to his home |
| C．treated hospitably at his home | D．treated to dinner in a restaurant |
The underlined words “generous with our time” in Paragraph 3 probably mean ______.
| A．willing to spend time | B．serious with time |
| C．careful with time | D．strict with time |
A suitable title for this passage would probably be “______”.
| A．Friendships between Chinese | B．Friendships between Americans |
| C．Americans’ hospitality | D．Americans’ and Chinese’s views of friendships |
When talking with young Swedish students, Mo Yan showed respect for Chinese authors that he learned writing from, particularly Shen Congwen, who was twice nominated（提名）for the Nobel Prize.
“Lu Xun, Lao She, Mao Dun and Shen Congwen, they are more qualified（有资格的）for the Nobel Prize than me,” he said,. Among the writers he learned from, he said he especially felt close to Shen Congwen, as they have similar life experiences.
Both of them left school early and did not get formal education. Shen quit after high school and Mo only finished the fifth grade. They both joined the army after school. “ We both learned from the book of life,” said Mo.
The themes of their writing are also similar. Both writers have their hometown as the theme and root of their writings. Shen’works are mostly about his hometown, Xiangxi, and most of Mo’s stories are set in his hometown, Gaomi, in Shandong Province.
Mo said he also learned from Shen how to deal with characters in a fiction. Unlike most Chinese writers, Shen has a humanistic（人文主义的） touch towards all of his characters. Said Mo, “In his works, there are no particularly bad person or good person. Even gangsters（匪徒） and thieves have their humane（仁慈的）side,” he said.
“I try to use the same approach in my writing. It shows the ability of a novelist when he treats all the characters as humans,” he said.
Mo said he also learned Lu Xun’s depth and Lao She’s humor. “They are all my teachers, and I am the student,” he said. “I feel ashamed from my heart that teachers did not get the prize, but the student got it.”Which of the following is NOT mentioned as the similarity between Mo Yan and Shen Congwen?
