Recently a study, led by Pedro Hallal of the Federal University, suggests that nearly a third of adults, 31%, are not getting enough exercise. That rates of exercise have declined is hardly a new discovery. Since the beginning of the industrial revolution, technology and economic growth have helped to create a world in which taking exercise is more and more an option rather than a necessity. But only recently have enough good data been collected from enough places to carry out the sort of analysis Dr Hallal and his colleagues have engaged in.
There are common themes in different places. Unsurprisingly, people in rich countries are less active than those in poor ones, and old people are less active than young ones. Less obviously, women tend to exercise less than men—34% are inactive, compared with 28% of men. But there are exceptions. The women of Croatia, Finland, Iraq and Luxembourg, for example, move more than their male countrymen.
Malta wins the race for most slothful country, with 72% of adults getting too little exercise, and Swaziland and Saudi Arabia are in close behind, with 69%. In Bangladesh, just 5% of adults fail to exercise enough. Surprisingly, six Americans in ten are active enough according to Dr Hallal’s study, compared with fewer than four in ten British.
These high rates of inactivity are worrying. Human beings seem to have evolved(进化) to benefit from exercise while deliberately avoiding it whenever they can. In a state of nature it would be impossible to live a life that did not provide enough of it. But that is no longer the case. Actually lack of enough activity these days has nearly the same effect on life span(寿命) as smoking.
1.We may learn from Paragraph 1 that_________.
A. the decline of exercise rates is newly discovered
B. the study suggests 31% of female adults get too little exercise
C. the good enough data has been collected from only one country
D. the industrial revolution has changed the way people live to some degree
2. According to the study, women of Luxembourg_________.
A. have little time to exercise
B. hate to get regular exercise
C. take more exercise to lose weight
D. exercise more than men in their country
3.The underlined word “slothful” in Paragraph 3 most probably means_________.
A. powerful B. rich C. lazy D. unpopular
4. What can be the best title for the text?
A. Worldwide Lack of Enough Exercise
B. New Health Discovery

A recent study led by researchers from the National University of Singapore (NUS) has found a clear link between the color of a taxi and its accident rate. An analysis of 36 months of detailed taxi, driver and accident data from two fleets of yellow and blue taxis in Singapore suggested that yellow taxis have fewer accidents than blue taxis. The higher visibility (能见度) of yellow makes it less difficult for drivers to avoid getting into accidents with yellow taxis, leading to a lower accident rate.
The study was led by Prof Ho. To test whether there was a relationship between the color of a taxi and the number of accidents the taxi had, the research team analysed data collected by the largest taxi company in Singapore. The researchers found that yellow taxis have about 6. 1 fewer accidents per 1,000 taxis per month.
They also studied the economic effect of changing the color of the entire fleet of taxis to yellow. The Singapore taxi company involved in the study owns about 16,700 taxis in a ratio(比例) of one yellow to three blue taxis. If a commercial decision is made to switch from blue to yellow taxis, 76.6 fewer accidents will occur per month or 917 fewer accidents per year.
Assuming an average repair cost of $1,000 per car and a downtime of six days, the color of all taxis to yellow could produce an annual saving of $ 2 million.
“We are eager to continue to validate (证实) the findings of our study by looking at the use of yellow in other types of public transport, such as school buses. For example, we hope to compare the accident rates of yellow school buses against those of other colors to find out if yellow is indeed a safer color for school buses. Besides, we’re also interested to look at private-hire vehicles and do a comparison of the accident rates of vehicles that are of different colors.” Explained Prof Ho.
1.Why do yellow taxis result in fewer accidents?
A. Because yellow can be seen more easily.
B. Because yellow signals a warning of danger.
C. Because drivers tend to be more careful in yellow taxis.
D. Because people act more quickly in yellow surroundings.
2.What’s Prof Ho’s study based on?
A. Physical risks taxi passengers experience.
B. The economic effect of changing taxi color.
C. Data from Singapore’s largest taxi company.
D. Personal reports from taxi drivers worldwide.
3.What do Prof Ho’s words in the last paragraph suggest?
A. School buses should be painted yellow.
B. Their findings are worth popularizing.
C. Their study will be furthered.
D. Yellow should be widely used in public transport.
4.What can be the best title for the text?
A. Caution: yellow taxis ahead B. Safer to ride in yellow taxis
C. Why are yellow taxis preferred? D. How can colors help prevent accidents?

Now,a new study led by Mason,a behavioral biologist at the University of Guelph in Canada,shows that people who can consistently read cats' expressions belong to a special group:that of the cat whisperer, mostly young and female.
For the research,Mason and his colleagues created an online survey and invited Internet users to take part.The 6,329 participants from 85 countries watched between 2 to 20 short videos of cats' expressions, and then responded if they thought the cats were distressed or happy.These random users got an average of 11.85 out of 20 ratings correct-better than chance,but not by much.But about 13 percent of the survey takers were unusually skilled at reading cats' emotions,scoring at least 15 out of 20 correct-the so-called cat whisperers.Those who self-reported being young,female,and having professional veterinary （MEW)experience were most likely to score well.Surprisingly to Mason,cat ownership had no impact on the ability to interpret cat emotion.
＂In humans,facial expressions are a major-if underappreciated- form of human communication," says Mason."And recent research shows that a variety of animals,from rats to dogs to horses,also make facial expressions that clearly communicate how they're feeling,"she says.A study published earlier this year found that cats were no exception,while also suggesting that humans could comprehend subtle(微妙的）forms of cat communication,especially facial expressions.
Mikel Delgado,a cat-behavior expert,says that this study is a"great start"to cracking cat communication,but cautions against identifying a cat's emotional state based on one piece of information.＂There's still a lot for us to understand about cats' body language,"says Delgado.For instance,tail and ear position are also relevant signals to how a cat is feeling.
1.What do we know about the cat whisperers?
A.They often go into profession related to animals.
B.They are good at understanding cats' feelings.
C.They like making videos of cats' expressions.
D.They are most likely to own and raise cats.
2.What does the author mean by"cats were no exception"in Paragraph 3?
A.Cats share a variety of characteristics with rats and dogs.
B.Cats can make out facial expressions like human beings.
C.Cats take an interest in communicating with other animals.
D.Cats can convey their feelings through facial expressions.
3.What can we infer from Mikel Delgado's words?
A.We should be very cautious when we deal with cats.
B.Cats have better communication skills than other animals.
C.We shouldn't tell cats' feelings only through their facial expressions.
D.Cats are used to showing how they feel through their body language.
4.What is the authors purpose in writing the text?
A.To convince people of benefits of keeping pets.
B.To introduce a study of reading cats 'expressions.
C.To compare cats 'and human's facial expressions.
D.To clarify some misconceptions about communication.
