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 tend 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.”
小题1: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 |

C.fail to react quickly to potential dangers |
D.refuse to explain the reasons for their behavior |
答案
小题1:D
小题2:A
小题3:C
小题4:C
解析
试题分析:中国有句古语云:一心不可二用。而最近的一项研究就表明。那些经常一心多用的人往往就是同时做两件事做的最糟糕的人。正是因为不能专注于一件事,才会同时多做几件事,结果可想而知。
小题1:细节理解题。根据全文第一句话可知,一心多用,往往会把事情做得更糟糕。故选D。
小题2:细节理解题。根据第二段最后一句话可知,然后他们要这些学生一面做一些数学运算, 一面记忆一组字母, 用这个很刁难的方法来测试这些学生一心多用的能力。和A项意思一致 。
小题3:细节理解题。根据全文第二句的but because they are easily distracted (分心) and can’t focus on one activity.可知,许多人一心多用, 并不是因为他们想要增强工作生产量, 而是因为他们很容易分心或是不能专注于做一件事。故选C。
小题4:推理判断题。由最后一段的People who are multitasking are generally less sensitive to risky situations.一心多用的人一般对危险的情形不太敏感。可知,对危险的事情,一心多用者往往对潜在的危险不能迅速判断。故选C。

举一反三
Dear Mayor,I would like to draw your attention to the depressing state of the environment in our city. Increased vehicles have made the air polluted. Citizens find it difficult to breathe. Dumping toxic chemicals into the river has polluted the drinking water and ground water.
All of us, as concerned citizens, have discussed these problems in various meetings. We have come up with the following proposals(提议).
The green roads are no longer green. Many trees and bushes have been cut. We propose restricting the movement of vehicles. Besides, we should make it compulsory(强制性的)to use anti-pollution devices on all vehicles. We should also plant more plants and trees along roads.
The Bada Nadi River has become a dumping ground of toxic chemicals from some factories. These toxic chemicals have killed nearly all the life in the river and polluted our drinking water and ground water. We propose that the Bada Nadi River be declared a protected water body. All the dumping should be banned and heavy fine should be imposed on the offenders(违法者). To tackle the problem of managing toxic waste, we propose setting up a water treatment plant so that only clean water is discharged into the river. Cleaning up the river and introducing various fishes and plants to the river will bring it back to life.
Lastly, the noise pollution caused by honking(鸣)horns and blaring loudspeakers has caused distress to one and all. Many people have suffered from noise-related illnesses. We propose a blanket ban on the use of loudspeakers. And“no horn zones”should also be declared in residential hospitals and school areas.
I would request you to seriously consider our proposals and act accordingly.
Thank you!
Sincerely yours,
A kind-hearted citizen

If you"re networking (建立人际关系) and nothing is happening, you might need to evaluate how you"re doing it. Maybe you show up at each event and still feel challenged by the process. You aggressively talk to people, give out your cards, call endlessly to schedule an appointment but have no real success from your efforts. To help you gain a different future, here are ten habits you should avoid.Ineffective networkers:
1. Lack patience. They expect immediate results and want business now, not tomorrow.
2. Constantly “selling” something. They see dollar signs every time they shake hands with someone.
3. Too many choices. If they offer a variety of products, they might try too hard to tell about all of them. Offering too much information sends a confusing message making it difficult for people to send referral (指点). Opportunities are all around us but when you"re networking, only focus on one.
4. Change positions too often. If they move from company to company or do something totally different, it might be difficult for people to keep up with them.
5. Lack manners and respect. They interrupt others, talk with food in their mouth, aren"t very polite and appear unprofessional. They call people during dinner or on the weekends without thinking whether the occasion is suitable.
6. Distribute too many cards and sales literature. They come while loading with brochures, flyers (传单), catalogues and samples.
7. Focus on themselves. Too much self promotion can leave the other person to feel unappreciated. Every sentence begins with “I” and is all about their business.
8. “Talking” instead of “giving”. They don"t realize what other people sense when they are being very selfish. Others may think that they are being taken advantage of.
9. Lack authenticity (可靠性) and personal values. They may create unrealistic expectations and not deliver on their promises. Sometimes doing things without integrity (诚实) possibly twists the truth.
10. Poor communication and interpersonal skills. They have trouble speaking effectively, building relationships and following up.
Networking is a process that is an investment of time and money. If you find you"re doing any of these habits, consider learning how to improve on these and maximize your results while networking. You"ll start to get better at connecting with people and obtain more referrals.

Teaching a child to read at a young age gives him a valuable start in life. Reading is the basic part of education and a child’s reading ability will influence his school success greatly. Learning difficulties, many of which begin from poor reading skills, can damage a school child’s confidence and affect his future achievement. Young children are programmed to learn and they can learn better with encouragement. Ten to twenty minutes of reading a day still leaves plenty of time for play.Many parents are concerned that learning to read is too challenging a task for a pre-school child, but they should also remember that most children learn to speak by the time they are 3. Learning a language is probably the single most challenging task any individual can undertake, yet children do it without formal instruction, achieving the fluency much better than adult language students.
There is a window of opportunity in terms of IQ development, which is most open during a child’s early years. A scientific study, carried out by Dr. Peter Huttenlocher at the University of Chicago, showed that the number of connectors, called synapses(神经元突触), between the nerve endings in a newborn baby’s brain is similar to the number in the average adult brain. These synapses increase rapidly during early childhood. By 12-24 months a child’s brain has about 50% more synapses than the average adult brain. After that the synapses which are not in use begin to atrophy(衰退). For most people, from age 16, the number remains steady. It begins to drop again as we move into our golden years. Doing intellectual activities at a young age, such as learning to read, can stimulate(刺激)and preserve these connectors in the brain resulting in a long-term beneficial(有益的)effect on IQ development.
Another notable study is probably the Milwaukee project. This study took a group of babies, all of whose mothers had low IQs, and gave them special training for seven hours a day, five days a week, until they started first grade. By the age of 6 these children had an average IQ 30 points higher than their contemporaries. The overwhelming conclusion is that the early intellectual stimulation can have a positive, long-term effect on a child’s brain development.
From birth you should talk to and explain things to your baby. Reading to him can be a wonderful way of spending quality time with your child. The enjoyment of books and being familiar with the idea of print will pave the way for(为……铺平道路)learning to read later.
If your child is a fast learner you can help him realize his potential by introducing him to the joy of the printed word at an early age. This will lay the foundations(基础)for both a high achieving school career and a lifelong love of reading. If your child shows early signs of reading difficulties, your efforts may help him get rid of such problems before he goes to school.
It can be difficult to teach your own child because emotional(引起情绪激动的)issues arise easily. Online programs for learning to read English are excellent options. They allow children to repeat new materials as many times as they need to, without wearing out the parents’ patience.

The designer says he came up with the idea after watching people get wet on streets in Russia. “Once, I was driving on a central Saint Petersburg street and saw the street lamps lighting up people trying to hide from the rain. I thought it would be appropriate to have a canopy(伞蓬)built into a street lamp,” he said.
The Lampbrella is a standard-looking street lamp fitted with an umbrella canopy. It has a built-in electric motor which can open or close the umbrella on demand. Sensors(传感器)then ensure that the umbrella offers pedestrians (行人) shelter whenever it starts raining.
In addition to the rain sensor, there’s also a 360° motion sensor on the fiberglass street lamp which detects whether anyone is using the Lampbrella. After three minutes of not being used the canopy is closed.
According to the designer, the Lampbrella would move at a relatively low speed, so as not to cause harm to the pedestrians. Besides, it would be grounded to protect from possible lightning strike. Each Lampbrella would offer enough shelter for several people. Being installed at 2 meters off the ground, it would only be a danger for the tallest of pedestrians.
While there are no plans to take Lampbrella into production, Belyaev says he recently introduced his creation to one Moscow Department, and insists this creation could be installed on any street where a lot of people walk but there are no canopies to provide shelter.
小题1:For what purpose did Belyaev create the Lampbrella?
A.To predict a heavy rain. |
B.To check the weather forecast. |
C.To protect people from the rain. |
D.To remind people to take an umbrella. |
A.His creation was inspired by an experience. |
B.It rains a lot in the city of Saint Petersburg. |
C.Street lamps are protected by canopies. |
D.He enjoyed taking walks in the rain. |
A.motor→canopy→sensors | B.sensors→motor→canopy |
C.motor→sensors→canopy | D.canopy→motor→sensors |
A.The designer will open a company to promote his product. |
B.The Lampbrella could be put into immediate production. |
C.The designer is confident that his creation is practical. |
D.The Lampbrella would be put on show in Moscow. |
They examined differences between red squirrels and gray squirrels in the American state of Indiana. The scientists wanted to know how these differences could affect the growth of black walnut (黑胡桃) trees. The black walnut is the nut of choice for both kinds of squirrels. The black walnut tree is also a central part of some hardwood forests.
Rob Swihart of Purdue University did the study with Jake Goheen, a former Purdue student now at the University of New Mexico. The two researchers estimate that several times as many walnuts grow when gathered by gray squirrels as compared to red squirrels. Gray squirrels and red squirrels do not store nuts and seeds in the same way. Gray squirrels bury nuts one at a time in a number of places. But they seldom remember where they buried every nut. So some nuts remain in the ground. Conditions are right for them to develop and grow the following spring. Red squirrels, however, store large groups of nuts above ground. Professor Swihart calls “death traps for seeds”.
Gray squirrels are native to Indiana. But Professor Swihart says their numbers began to decrease as more forests were cut for agriculture. Red squirrels began to spread through the state during the past century.
The researchers say red squirrels are native to forests that stay green all year, unlike walnut trees. They say the cleaning of forest land for agriculture has helped red squirrels invade Indiana. Jake Goheen calls them a sign of an environmental problem more than a cause.
小题1:The study done by Rob Swihart and Jake Goheen is to ________.
A.find out the living conditions for squirrels |
B.learn squirrels’ influence on black walnut trees |
C.do something to get rid of squirrels |
D.save the forests in the American state of Indiana |
A.the way they gather the walnut |
B.the time they have winter sleep |
C.the place they have winter sleep |
D.the place they store the walnuts |
A.red squirrels eat more nuts than gray squirrels |
B.gray squirrels and red squirrels will have severe fights |
C.nuts above the ground will not develop into plants |
D.seeds can be traps for other animals in the forest |
A.The black walnut is equally attractive to both gray and red squirrels. |
B.Gray squirrels do more harm to the forest than red squirrels. |
C.Red squirrels and gray squirrels have helped the spread of walnut trees. |
D.The cleaning of forest land benefits red squirrels directly. |
