Sports shoes that work out whether their owner has enough exercise to warrant 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 passes the information to a receiver connected to a television, and this decides how much evening viewing time the wearer deserves, 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 to 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 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 precisely 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.”

1.According to Swan, the purpose of her design project is to ________.

A. keep a record of the steps of the wearer

B. deal with overweight among teenagers

C. enable children to resist the temptation of TV

D. prevent children from being tricked by TV programs

2.Which of the following is TRUE of Square Eyes shoes?

A. They regulate a child’s evening TV viewing time.

B. They determine a child’s daily pocket money.

C. They have raised the hot issue of overweight.

D. They contain information of the receiver.

3.What is stressed by health experts in their suggestion?

A. The exact number of steps to be taken.

B. The precise number of hours spent on TV.

C. The proper amount of daily exercise and TV time.

D. The way of changing steps into TV watching time.

4.Which of the following would be the best title for the text?

A. Smart Shoes Decide on Television Time

B. Smart Shoes Guarantee More Exercise

C. Smart Shoes Measure Time of Exercise

D. Smart Shoes Stop Childhood Overweight

My students often tell me they don’t have “enough time” to do all their schoolwork. My reply is often brief –You have as much time as the president. I usually carry on a bit about there being 24 hours per 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 justify myself to one of my professors by saying that I was working. His answer to me was, “That’s irrelevant. What’s important is the quality of your work.” Since then I have had time to reflect on the “hard worker” dodge(伎俩), and I have come to some conclusions – all relevant to the issue of how much time we have.

If you look at the matter analytically, 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 issue of “work” during that time, which can vary in intensity. But, as my professor suggested, it’s not diligence but the quality of the product that is important.

That led me to a new idea, the quality of work. That concept is perhaps best explained by a sign I once saw on the wall in someone’s office – Don’t work harder but work smarter! There’s 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 work. That means thinking of ways of getting 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 “learning 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 across the board in all your studies.

Why do men die earlier than women? The latest research makes it known that the reason could be that men’s hearts go into rapid decline when they reach middle age.

The largest study of the effects of aging on the heart has found that women’s longevity may be linked to the fact that their hearts do not lose their pumping power with age.

“We have found that the power of the male heart falls by 20--25 percent between 18 and 70 years of age,” said the head of the study, David Goldspink of Liverpool John Moores University in the UK.

“Within the heart there are millions of cells that enable it to beat. Between the age of 20 and 70, one-third of those cells die and are not replaced in men,” said Goldspink. “This is part of the aging process.”

What surprises scientists is that the female heart sees very little loss of these cells. A healthy 70-year-old woman’s heart could perform almost as well as a 20-year-old one’s.

“This gender difference might just explain why women live longer than men,” said Goldspink.

They studied more than 250 healthy men and women between the ages of 18 and 80, focusing on healthy persons to remove the confusing influence of disease.

The team has yet to find why ageing takes a greater loss on the male heart, said Goldspink.

The good news is that men can improve the health of their heart with regular exercise. Goldspink stressed that women also need regular exercise to prevent their leg muscles becoming smaller and weaker as they age.

1.The underlined word “longevity” in the second paragraph probably refers to ______.

A. health B. long life C. aging D. effect

2.The text mainly talks about ______.

A. men’s heart cells B. women’s aging process

C. the gender difference D. hearts and long life

3.According to the text, the UK scientists have known that ______________.

A. women have more cells than men when they are born

B. women can replace the cells that enable the heart to beat

C. the female heart loses few of the cells with age

D. women never lose their pumping power with age

4.If you want to live longer, you should ___________.

A. enable your heart to beat much faster

B. find out the reason for aging

C. exercise regularly to keep your heart healthy

D. prevent your cells from being lost

5.We can know from the passage that __________.

A. the reason why aging takes a greater loss on the male heart has been found out

B. scientists are on the way to finding out why the male heart loses more of the cells

C. the team has done something to prevent the male from suffering the greater loss

D. women over 70 could lose more heart cells than those at the age of 20

Easy Ways to Keep Your Brain Sharp

Everyone is forgetful, but as we age, we start to feel like our brains are slowing down a bit—and that can be a very annoying thing. 1. Read on for some techniques worth trying.

1. 2.

People who regularly made plans and looked forward to upcoming events had a 50 percent reduced chance of Alzheimer's disease (早老性痴呆症), according to a recent study. 3.

Something as simple as setting a goal to have a weekly coffee date with a friend will do. There's evidence that people who have a purpose in life or who are working on long or short-term goals appear to do better. In other words, keep your brain looking forward.

2. Go for a walk.

Mildly raised glucose (葡萄糖) levels can harm the area of the brain that helps you form memories and physical activity can help get blood glucose down to normal levels. In fact, exercise produces chemicals that are good for your brain. 4.

3. Learn something new.

Take a Spanish class online, join a drawing club, or learn to play cards. A study found that mental stimulation (刺激) limits the weakening effects of aging on memory and the mind. But the best thing for your brain is when you learn something new and are physically active at the same time. 5. Or go dancing with your friends.

A. Focus on the future.

B. This can be especially harmful to the aged.

C. It should be something like learning gardening.

D. So take a few minutes each day to do some reading.

E. But don't worry if your schedule isn't filled with life-changing events.

F. Luckily, research shows there is a lot you can do to avoid those moments.

G. In other words, when you take care of your body, you take care of your brain.

根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。其中两项为多余选项

Before going outside in the morning, many of us check a window thermometer(温度计)for the temperature. This helps us decide what to wear. ____1.____. We want our food to be a certain coldness in the refrigerator. We want it a certain hotness in the oven. If we don’t feel well, we use a thermometer to see if we have a fever. We keep our rooms a certain warmth in the winter and a certain coolness in the summer.

Not all the thermometers use the same system to measure temperature. We use a system called the Fahrenheit scale. But most other countries use the Centigrade scale.

Both systems use the freezing and boiling points of water as their guide.___ 2.___ .

The most common kind of thermometer is made with mercury(水银)inside a clear glass tube. As mercury (or any other liquid ) becomes hot, it expands. As it gets colder, it contracts(收缩). That is why on hot days the mercury line is high in the glass tube.____ 3.___.

First. Take a clear glass juice bottle that has a cap ; fill the bottle with coloured water. Tap a hole in the center of the cap using a hammer and thick nail. Put the cap on the jar. Then stick a plastic straw(吸管) through the nail hole.

_____4.____.

Finally. Place a white card on the outside of the bottle and behind the straw. Now you can see the water lever easily.

_____5.____.

As the temperature goes down, the water will contract, and the lever in the straw will come down. Perhaps you will want to keep a record of the water lever in the straw each morning for a week.

A.We use and depend on thermometers to measure the temperature of many other things in our daily lives.

B.Thermometers measure temperature, by using materials that change in the same way when they are heated or cooled.

C.Now that you know this rule you can make a thermometer of your own that will work.

D.The water will rise in the straw. As the temperature of the air goes up, the water will expand and rise even higher.

E.They label these in different ways. On the Fahrenheit scale water freezes at 32 degrees and boils at 212 degrees. On the Celsius scale water freezes at 0 degrees and boils at 100degrees.

F.Take wax (you may use an old candle if you have one) and melt some of it right where the straw is struck into the cap to seal把..粘住) them together.

G.People use thermometers which are made by themselves when travelling around the world.
