16．Don't run less hard．Don't run less often．Don't run less distance．And don't be persuaded by underpowered medical studies-a habit that really could harm your health．
I say this in response to a recent study suggesting that too much strenuous jogging shortens your life．The conclusions，published in the Journal of the American College of Cardiology，have received wide attention this week．
In fact，the main thing the study shows is that small samples produce unreliable estimates that cannot be reliably discerned（识别） from the effects of chance．And the main thing the reaction shows is that perhaps we are all a bit too quick to believe medical studies that tell us what we want to hear．
Let's start by taking a closer look at what the study actually says．The researchers asked Danish runners about the speed，frequency and duration（持续） of their workouts，categorizing 878of them as light，moderate or strenuous joggers．Ten years later，the researchers checked government records to see how many of them had died．
Happily，only 17had．While this was good news for the surviving runners，it was bad news for the researchers，because 17was clearly too few deaths to figure out whether the risk of death was related to running intensity（强度）．
However，the study claimed that too much jogging was associated with a higher death rate．At a literal level，the death rate was highest among those who ran the most and at the highest intensity．But the evidentiary basis for this claim is weak．It is based on 40people who were categorized as"strenuous joggers"-among whom only two died．
Needless to say，these two deaths do not add up to a statistically significant finding．Moreover，the researchers do not even report whether those two deaths were from causes that could plausibly be related to running．
The death rate among moderate joggers was also higher than that for light joggers，but given that there were fewer than 10deaths among either category，this difference could not be reliably discerned from the effects of chance．
To get a sense of what we are learning，let me recommend a careful review of the literature，written by Mr．Hutchinson，a physicist-turned-writer．
His conclusion："Running an hour a day is certainly no less healthy，and probably a bit healthier，than running less．"Armed with that more accurate assessment of the science，I hope to see you on the running trails．

71．The recent study about running shows thatB．
A．running is of great help to your health
B．running could do damage to your health
C．running enables you to live longer

B．people were glad that only 17people died among the runners
C．people tend to believe in some medical studies blindly
D．it takes a long while for people to accept the findings of some medical studies

3．Children start out as natural scientists，eager to look into the world around them．Helping them enjoy science can be easy； there is no need for a lot of scientific terms or expensive lab equipment．You only have to share your children's strong desire to know about things．Firstly，listen to their questions．I once visited a classroom of seven-year-olds to talk about science as a job．The children asked me"textbook questions"about schooling，salary and whether I liked my job．When I finished answering，we sat facing one another in science．Finally I said，"Now that we've finished with your lists，do you have questions of your own about science？"
After a long pause，a boy raised his hand，"have you ever seen a grasshopper （蚱蜢） eat？When I try eating leaves like that，I get a stomachache．Why？"
This began a set of questions that lasted nearly two hours．
Secondly，give them time to think．Studies over the past 30years have shown that．After asking a question，adults typically wait only one second or less for an answer，no time for a child to think．When adults increase their"wait time"to three seconds or more，children give more logical，complete and creative answers．
Thirdly，watch your language．Once you have a child involved in a science discussion，don't jump in with"That's right"or"very good"．These words work well when it comes to encouraging good behavior．But in talking about science，quick praise can signal that discussion is over．Instead，keep things going by saying，"That's interesting"or"I'd never thought of it that way before"，or coming up with more questions or ideas．
Never push a child to"think"．It doesn't make sense； children are always thinking，without your telling them to．What's more，this can turn a conversation into a performance．The child will try to find the answer you want，in as few words as possible，so that he will be a small target for your disagreement．
Lastly，show； don't tell．Real-life impressions of nature are far more impressive than any lesson children can learn from a book or a television program．Let children look at their fingertips through a magnifying glass，and they'll understand why you want them to wash before dinner．Rather than saying that water evaporates（蒸发），set a pot of water to boil and let them watch the water level drop．

32．According to the passage，children are natural scientists，and to raise their interest，the most important thing for adults to do isB．
A．to share the children's curiosity
B．to let them see the world around
C．to explain difficult phrases about science

20．What makes one person more intelligent than another？What makes one person a genius，like the brilliant Albert Einstein，and another person a fool？Are people born intelligent or stupid，or is intelligence the result of where and how you live？These are very old questions and the answers to them are still not clear．
We know，however，that just being born with a good mind is not enough．In some ways，the mind is like a leg or an arm muscle．It needs exercise．Mental exercise is particularly important for young children．Many child psychologists （心理学家） think that parents should play with their children more often and give them problems to think about．The children are then more likely to grow up bright and intelligent．If，on the other hand，children are left alone a great deal with nothing to do，they are more likely to become dull and unintelligent．
Parents should also be careful with what they say to young children．According to some psychologists，if parents are always telling a child that he or she is a fool or an idiot，then the child is more likely to keep doing silly and foolish things．So it is probably better for parents to say very positive things to their children，such as"That was a very clever thing you did．"or"You are such a smart child．"
31．The words"intelligent"and"brilliant"in the first paragraph probably meanA while"dull"in the second paragraph meansA．

1．While most people consider that laughter is one of the nature's great treatments for a whole range of mental and physical diseases，it is still a serious scientific subject that researchers are trying to figure out．
"Laughter is social．"says Robert R．Provine，author of the book"Laughter：A Scientific Investigation"，who has been studying laughter for decades．"Almost all people laugh‘ha-ha-ha'basically the same way．Whether you speak Mandarin，French or English，everyone will understand laughter．There is a pattern generator（发生器） in our brain that produces this sound．
Laughing is also a good way of communicating．Babies laugh long before they speak．No one teaches them how to laugh．They just do it．People may laugh at a prank（恶作剧） on April Fools'day．But surprisingly，only 10to 15percent of laughter is the result of someone making a joke．Laughter is mostly about social responses rather than reaction to a joke．Deaf people laugh without hearing and people on cell phones laugh without seeing，which shows that laughter isn't dependent on a single sense but on social interactions．
And laughter is not just a human thing．Chimps tickle（挠痒） each other and even laugh when another chimp pretends to tickle them．
Jaak Panksepp studies rats that laugh when he tickles them．It turns out rats love to be tickled．They return again and again to the hands of researchers tickling them，Panksepp's video shows．
By studying rats，scientists can figure out what's going on in the brain during laughter．It has been found that laughter in rats produces a chemical that acts as an antidepressant（抗抑郁药） and anxiety-reducer．Scientists think the same thing probably happens in humans，too．This would give doctors a new chemical target in the brain in their effort to develop drugs that fight depression and anxiety in people．
Even so，laughter itself has not been proved to be the best medicine，experts said．"No study has shown that laughter produces a direct health benefit，"Provine said，"largely because it's hard to separate laughter from just feeling good．"
64．Why does the writer say"laughter is mostly about social responses rather than reaction to a joke"？A
A．because people can communicate with each other by laughing．
B．because laughter is the same sound in all the human's languages．
C．because laughter is considered a basic language all people can learn．
D．because everyone can understand the meaning of the word laughter．
65．From the last two paragraphs we know thatC．
A．laughter has no direct connection with good feelings
B．laughing every day can cure people of many diseases
C．the medical functions of laughter are still under experiment
D．scientists have learned what is happening in a human brain when he laughs
66．Which of the following statements is true according to the passage？B
A．Laughter depends on many senses．
B．Laughter is a social response shared by all creatures．
C．If you speak different languages，you will laugh differently．
D．A new medicine has been developed based on the laughter research．
