Sports shoes that work out whether their owner has done enough exercise to promise time in front of the television have been devised in the UK.
The shoes- named Square Eyes- contain an electronic pressure sensor and a tiny computer chip to record how many steps the wearer has taken in a day. A wireless transmitter (发射器) passes the information to a receiver connected to a television, and this decides how much evening viewing time the wearer deserves(应得), based on the day's efforts.
The design was inspired by a desire to fight against the rapidly ballooning waistlines among British teenagers, says Gillian Swan, who developed Square Eyes as a final year design project at Brunel University in London, UK. "We looked at current issues and childhood overweight really stood out," she says. "And I wanted to tackle that with my design."
Once a child has used up their daily allowance gained through exercise, the television automatically (自动地) switches off. And further time in front of the TV can only be earned through more steps. Swan calculated how exercise should translate to television time using the recommended daily amounts of both. Health experts suggest that a child take 12,000 steps each day and watch no more than two hours of television. So, every 100 steps recorded by the Square Eyes shoes equals exactly one minute of TV time.
Existing pedometers(计步器) normally clip onto a belt or slip into a pocket and keep count of steps by measuring sudden movement. Swan says these can be easily tricked into recording steps through shaking. But her shoe has been built to be harder for lazy teenagers to cheat. "It is possible, but it would be a lot of effort," she says. "That was one of my main design considerations."

As a professor at a large American university,there is a phrase that I hear often from students:“I’m only a 1050.”The unlucky students are speaking of the score on the Scholastic Aptitude Test(SAT),which is used to determine whether they will be admitted to the college or university of their choice,or even if they have a chance to get a higher education at all.The SAT score,whether it is 800,1100 or 1550,has become the focus at this time of their life.
It is obvious that if students value highly their test scores,then a great amount of their self-respect is put in the number.Students who perform poorly on the exam are left feeling that it is all over.The low test score,they think,will make it impossible for them to get into a good college.And without a degree from a prestigious university,they fear that many of life’s doors will remain forever closed.
According to a study done in the 1990s,the SAT is only a reliable indicator of a student’s future performance in most cases.Interestingly,it becomes much more accurate when it is set together with other indicators-like a student’s high school grades.Even if standardized tests like the SAT could show a student’s academic proficiency(学业水平),they will never be able to test things like confidence,efforts and willpower,and are unable to give us the full picture of a student’s potentialities(潜力).This is not to suggest that we should stop using SAT scores in our college admission process.The SAT is an excellent test in many ways,and the score is still a useful means of testing students.However,it should be only one of many methods used.
【小题1】The purpose of the SAT is to test students’______.
A.strong will |
B.academic ability |
C.full potentialities |
D.confidence in school work |
A.scores in the SAT |
B.achievements in mathematics |
C.job opportunities |
D.money spent on education |
A.a famous university |
B.a technical university |
C.a traditional university |
D.an expensive university |
A.how to prepare for the SAT |
B.stress caused by the SAT |
C.American higher education |
D.the SAT and its effects |
My students often tell me that they don’t have “enough time” to do all their schoolwork.
My reply is often a brief “You have as much time as the president.” I usually carry on a bit about there being twenty-four hours in the day for everyone, and suggest that “not enough time” is not an acceptable explanation of not getting something done.
Once in graduate school, I tried to prove to one of my professors by say
ing that I was working hard. His answer to me was, “That’s irrelevant (无关的). Wh
at’s important is the quality of your work.” Since then I have had time to think carefully about the “hard worker” dodge (诀窍), and I have come to some conclusions — all relevant to the problem of how much time we have.
If you analyze the matter, you can identify two parts of the problem: There is, of course, the matter of “time”, which we can think of as fixed. Then there is the problem of “work” during that time. But, as my professor suggested, it’s not how hard one works but the quality of the product that’s important.
That led me to a new idea: the quality of the work. That concept is perhaps best explained by a sign I once saw on the wall in someone’s office: “Don’t work harder. Work smarter.” There is a lot of sense in that idea.
If you can’t get more time, and few of us can, the only solution is to improve the quality of the work. That means thinking of ways to get more out of the same time than we might otherwise get. That should lead us to an analysis of our work habits. Since “work” for students usually means “homework”, the expression “work habits” should be read as “study habits”.
Then, as a smart student, you will seek to improve those skills that you use in study, chiefly reading and writing. If you learn to read better and write better, there are big benefits that pay off in all your studies.

Motherhood may make women smarter and may help prevent dementia(痴呆) in old age by bathing the brain in protective hormones(荷尔蒙) , U.S. researchers reported on Thursday.
Tests on rats show that those who raise two or more litters of pups do considerably better in tests of memory and skills than rats who have no babies, and their brains show changes that suggest they may be protected against diseases such as Alzheimer’s (早老痴呆症). University of Richmond psychology professor Craig Kinsley believes his findings will translate into humans.
“Our research shows that the hormones of pregnancy (怀孕) are protecting the brain, including estrogen (雌激素), which we know has many neuroprotective (保护神经的) effects,” Kinsley said.
“It’s rat data but humans are mammals just like these animals are mammals,” he added in a telephone interview. “They go through pregnancy and hormonal changes.”
Kinsley said he hoped public health officials and researchers will look to see if having had children protects a woman from Alzheimer’s and other forms of age-related brain decline.
“When people think about pregnancy, they think about what happens to babies and the mother from the neck down,” said Kinsley, who presented his findings to the annual meeting of the Society of Neuroscience in Orlando, Florida.
“They do not realize that hormones are washing on the brain. If you look at female animals who have never gone through pregnancy, they act differently toward young. But if she goes through pregnancy, she will sacrifice her life for her infant—that is a great change in her behavior that showed in genetic alterations(改变) to the brain.”

I don’t ever want to talk about being a woman scientist again. There was a time in my life when people asked constantly for stories about what it’s like to work in a field dominated by men. I was never very good at telling those stories because truthfully I never found them interesting. What I do find interesting is the origin of the universe, the shape of space-time and the nature of black holes.
At 19, when I began studying astrophysics, it did not bother me in the least to be the only woman in the classroom. But while earning my Ph.D. at MIT and then as a post-doctor doing space research, the issue started to bother me. My every achievement--- jobs, research papers, awards --- was viewed through the lens of gender(性别)politics. So were my failures. Sometimes, when I was pushed into an argument on left brain versus right brain, or nature versus nurture(培育, I would instantly fight fiercely on my behalf and all womankind.
Then one day a few years ago, out of my mouth came a sentence that would eventually become my reply to any and all provocations: I don’t talk about that anymore. It took me 10 years to get back the confidence I had at 19 and to realize that I didn’t want to deal with gender issues. Why should curing sexism be yet another terrible burden on every female scientist? After all, I don’t study sociology or political theory.
Today I research and teach at Barnard, a women’s college in New York City. Recently, someone asked me how many of the 45 students in my class were women. You cannot imagine my satisfaction at being able to answer, 45. I know some of my students worry how they will manage their scientific research and a desire for children. And I don’t dismiss those concerns. Still, I don’t tell them “war” stories. Instead, I have given them this: the visual of their physics professor heavily pregnant doing physics experiments. And in turn they have given me the image of 45 women driven by a love of science. And that’s a sight worth talking about.
72. Why doesn’t the author want to talk about being a woman scientist again?
She feels unhappy working in male-dominated fields.
She is not good at telling stories of the kind.
She finds space research more important.
She is fed up with the issue of gender discrimination.
73. From Paragraph 2, we can infer that people would attribute the author’s failures to ______.
her over-confidence as a female astrophysicist
the very fact that she is a woman
her involvement in gender politics
the burden she bears in a male-dominated society
74. Why does the author feel great satisfaction when talking about her class?
Her students’ performance has brought back her confidence.
Her female students can do just as well as male students.
More female students are pursuing science than before.
Female students no longer have to bother about gender issues.
75. What does the image the author presents to her students suggest?
A. Women students needn’t have the concerns of her generation.
Women have more barriers on their way to academic success.
Women now have fewer problems pursuing a science career.
Women can balance a career in science and having a family.
