Everyone knows that walking is one of the best means of exercise for health, so physicians often recommend 150 minutes a week. But that’s a measure of volume (量). What about the walking speed? Does that make a difference? A recent paper indicates the answer may be yes.
Previous research had only focused on total amounts of exercise in minutes or steps. A team of experts in Sydney looked at whether people who walked similar distances but at different speeds gained more or less health benefits
The researchers studied 11 English and Scottish population-wide reports that included more than 50,000 regular walkers with an average age of late 40s. The walkers were grouped according to four walking speeds: slow, average, brisk(轻快的) and fast. Lastly, the researchers figured out the death( from heart disease and cancer) rate during an average follow-up period of 9.2years.
New researchers showed marathoners had less arthritis(关节炎) than non-runners.
Participants who walked at an “average” speed, as opposed to ” slow ” , had a 20 percent lower risk of death. Those walking at a “ brisk ” or “ fast ” pace enjoyed an additional 4 percent lower death rate. While the best speeds vary with one’s own age and fitness, a pace below 20 minutes per mile is considered average, and below 18 minutes per mile is considered brisk. All the benefits came from lower heart-related deaths. Walking pace had no effect on cancer rates.
“Our paper is the first paper to keep apart walking pace from the physical activity volume ,”
Explained Emmanuel Stamatakis , a professor of the Charles Perkins Center. “We also took steps to role out ( 排除 ) the possibility that the slow walkers were in poor health to begin with.”
“Walking more is better than walking less. But don’t fall into the trap of thinking that any walk improve health. Keep out of the ‘ slow ’ zone. Make sure you’re putting some effort into your walk”, Stamatakis noted. “ An appropriate effort for those in a comfortable walking routine might be slightly out of breath.”
When you’re short of time, simply walk faster to increase the pay-off. “ A faster pace means you are challenging yourself to make adaptations for better health and fitness,” said Stamatakis.
1.What’s the finding of the recent paper?
A.Slow walkers are in poor health at first.
B.Walking speed influences one’s health.
C.Walking pace has some effect on cancer rates.
D.Walking 150 minutes a week is good for health.
2.How were the walkers sorted in the research?
A.They were divided into groups by walking pace.
B.They were put into different age group.
C.They were groups by health condition.
D.They were organized by nationality.
3.What can we know about the research?
A.Participants are from eleven countries.
B.Participants include people of all ages.
C.It collected data during an average of 9.2 years.
D.It focused on total amounts of exercise in minutes.
4.What’s Stamatakis’s advice for those in a comfortable walking routine?

Scientists believe that one of our most important means of knowing what is going on around us is the sense of sound. We are warned of danger by sounds. Sounds serve to please us in music. Sound has a waste product, too, in the form of noise. Noise has been called unwanted sound. Noise is growing and it may get much worse before it gets any better.
In order to know how noise affects people and animals, scientists have been studying for several years. They are surprised by what they have learned. Peace and quiet are becoming harder to find. Noise pollution is a threat that should be looked at carefully.
Sounds is measured in units called decibels (分贝). At a level of 140 decibels people feel pain in their ears.
Trucks , buses , motorcycles, airplanes, boats, factories---all these things make noise. They trouble not only our ears, but minds and bodies as well.
There is a saying that it is so noisy that you can’t hear yourself think. Doctors who study noise believe that we must sometimes hear ourselves think. If we don’t, we may have headaches, other aches and pains, or even worse mental problems.
Noise adds more tension (紧张) to a society that has already faced enough stress.
1.The sense of sound _________.
A. makes us feel excited
B. helps us hear more clearly
C. is something harmful to us
D. helps to know what is happening around us
2.When sound is turned into noise, ______________.
A. people grow worse and worse
B. it makes us forget all the past
C. people don’t know what to do with everyday life
D. it will be a kind of pollution to people
3.Why does the passage say peace and quiet are becoming harder to find?
A. Because the world is making more and more noise.
B. Because wars and battles happen here and there in the world.
C. Because all the sounds are becoming over 140 decibels.
D. Because some machines can make noise.
4.Doctors say we can hear ourselves think __________.
A. if we don’t like to hear noise
B. if we have no aches or pains in our bodies
C. if there isn’t too much noise
D. if we can’t be careful of noise

Everyone knows that death is natural, but do you have any idea of the process of dying? Modern scientists divide the process of dying into two periods—clinical or temporary death and biological death. Clinical death occurs when the important organs, such as the heart or lungs, have stopped to function, but have not suffered permanent damage. The organism (有机体) can still be revived. Biological death occurs when changes in the organism lead to the “breaking up” of important cells and tissues. Death is then unchangeable.
Scientists have been seeking a way to lengthen the period of clinical death so that the organism can remain alive before biological death occurs. The best method developed so far involves cooling of the organism, combined with narcotic (麻醉的) sleep. By slowing down the body’s metabolism (新陈代谢), cooling delays the processes leading to biological death.
To illustrate how this works, scientists performed an experiment on a six-year-old female monkey called Keta. The scientist put Keta to sleep with a narcotic. Then they surrounded her body with ice-bags and began checking her body temperature. When it had dropped to 28 degrees the scientists began draining blood from an artery (动脉). The monkey’s blood pressure decreased and an hour later both the heart and breathing stopped: clinical death set in. For twenty minutes Keta remained in this state. Her temperature dropped to 22 degrees. At this point the scientists pumped blood into an artery in the direction of the heart and started artificial breathing. After two minutes Keta’s heart became active once more. After fifteen minutes, spontaneous (自发的) breathing began, and after four hours Keta opened her eyes and lifted her head. After six hours, when the scientists tried to give her a penicillin injection, Keta seized the syringe (注射器) and ran with it around the room. It showed that Keta had nothing different from any other healthy animal.
1.For a person who suffers from the clinical death, _________.
A.he can’t avoid final death
B.he is still very much alive
C.his most important organs are damaged
D.he still has the possibility of getting back to life
2.Scientists try to make the time of clinical death longer in order to ________.
A.cool the organism
B.slow down the body’s metabolism
C.delay the coming of biological death
D.bring important cells and tissues back to active life
3.How did the scientists put Keta into clinical death?
A.By surrounding her body with ice-bags and draining her blood.
B.By lowing her blood pressure and stopping her heart from beating.
C.By putting her to sleep, lowering her temperature and draining her blood.
D.By draining her blood, lowering her blood pressure and stopping her breathing.
4.Which of the following indicates that Keta is a healthy animal after the experiment?
A.Her heart beat again.
B.She seized the syringe and ran away with it.
C.She regained her normal breath.
D.She opened her eyes and lifted her head.

高一英语七选五中等难度题查看答案及解析
There is one word that is on the lips of Americans, day and night: “Sorry.”
One time as I was walking on the street, a young man ran by hurriedly, brushing against my handbag. Even as he continued on his way, he turned back and said “sorry” to me. Even in a rush, he didn’t forget to apologize. One day, after I bought a mango, the salesman was giving me the change, but I wasn’t ready for it and a coin dropped to the ground. “I’m sorry,” he said while bending down to pick it up. I was puzzled—why would he apologize when it is my fault?
Another time, I stepped on a man’s foot in an escalator, at the same time, we both said “sorry”. I thought it interesting, was it really necessary for him to apologize? Later on, an American friend explained to me that according to the American mentality, the escalators a public place, and everyone should be able to stand in it. After someone occupies a position in the elevator, making it difficult for someone else to find a place to stand, isn’t it necessary to express an apology?
If you go to the movies and the tickets happen to be sold out, the ticket seller will say: “Sorry, the tickets are sold out.” Whenever one of your hopes goes unfulfilled, an American will say “sorry” as a sign of sympathy.
During my stay in America, I often came across situations in which I was supposed to say “sorry”. Gradually, I realized that when friction（摩擦）appears in daily life, Americans don’t care much about who is wrong; If someone is troubled, a “sorry” is always necessary. When this happens, even if the other person is hurt, the “sorry” cools tempers and human kindness is shown. Perhaps this is why I never saw anyone quarreling on the buses, subways or streets of America.
1.How many examples are given to show that Americans like to say “sorry”?
A．One B．Two C．Three D．Four
2.When the author was walking on the street, a young man ran by hurriedly ______.
A．and took away his bag B．and touched his bag
C．to help him with his bag D．to brush his bag
3.Which of the following plays a different role in the passage?
A．Paragraph 2 B．Paragraph 3 C．Paragraph 4 D．Paragraph 5
4.At last, the author’s attitude towards the Americans’ “sorry” seems to be ______.
A．angry B．interested C．approving(赞成) D．disappointed
5.The best title for the passage can be “_______”.
A．My life in America B．Americans’ “sorry”
C．My experience in an escalator D．The meaning of “sorry”

While many people agree that The Sound of Music（音乐之声）is one of the best films of all time, some are at a loss（困惑） to explain why. Well, I’ll tell you why it’s one of the best movies ever. The Sound of Music simply has everything one could want in a movie.
First of all, it has a real romance--one where you can watch the characters slowly fall in love.
Secondly, it has humor, clever and sarcastic（讽刺性的） humor. When Schraeder said, “ Bye, Maria, I’m sure you’ll make a fine nun（修女）.” You just want to slap（掴） her across the face after hearing that.
Thirdly, it’s got adventure. The Nazis are the worst “bad guys” in any movie, so it’s great to see Maria, the Captain and the kids outwit（智取） them.
Fourthly, it’s got great music. The songs of the film are popular all over the world.
Fifthly, it’s got great scenery. The plot（情节） and dialogue are also amazing. I find new things to admire each time I watch.
Finally, is there a greater scene in any movie than the nuns showing the stolen Nazi car parts? In short, the film doesn’t just succeed because it cheers people up with a beautiful love story or songs. It also succeeds because it’s a wonderfully-constructed, wonderfully-written, and wonderfully-acted movie.
