10．It's natural to greet friends with a smile and a wave．（31）G But what happens if your face and body send mixed messages？Would someone be more likely to believe the look on your face or the way you hold your body？
Scientists have recently tackled these questions．They found that when a person is looking at your face，she might not believe what she sees of your body language matches the feeling that your face shows．
（32）BPreviously，they had found that the tone of a person's voice can be more important than the words that are spoken．For example，most people tend not to believe a person who says in a flat voice，"I'm so excited．"
When it came to emotions conveyed by facial expressions and body language，most scientists suspected that the face was more important．To test if this was true，psychologists from the Netherlands and Boston showed people a number of pictures of isolated faces and isolated bodies（with faces blurred out） that showed anger or fear．（33）FAn angry face had low eyebrows and tight lips．A scared face had high eyebrow and a slightly open mouth．（34）EA scared body had arms forward and shoulders square，as if ready to defend．
These results told the researchers that mixed signals can confuse people．Even when people pay attention to the face，body language subtly influences which emotion they read．（35）D And if you want to be understood，it helps to avoid sending mixed messages．
A．Scientists feel new to study the mixed message that confuses people．
B．Studying such mixed messages is nothing new for scientists．
C．Body language can sometimes be misunderstood in different culture backgrounds．
D．So，your body language is important for telling people how you feel．
E．An angry body had arms back and shoulders at an angle，as if ready to fight．
F．They also showed pictures in which angry or scared faces were paired with angry or scared bodies．
G．When you do this，your face and body work together to show your friends that you're happy to see them．

  Millions of people are using cell phones today．In many places，it is actually considered unusual not to use one．（31）B．They find that the phones are more than a means of communication-having mobile phone shows that they are cool and connected．
The explosions around the world in mobile phone use make some health professionals worried．Some doctors are concerned that in the future many people may suffer health problems from the use of mobile phones．Mobile phone companies are worried about the negative publicity（負面報道）of such ideas．（32）E．On the other hand，signs of change in the issues of the brain and head can be detected with modern scanning equipment．In one case，a traveling salesman had to retire at a young age because of serious memory loss．（33）F．This man used to talk on his mobile phone for about six hours a day，every day of his working week，for a couple of years．
（33）D？The answer is radiation（輻射）．High-tech machines can detect very small amounts of radiation from mobile phones．Mobile phone companies agree that there is some radiation，but they say the amount is too small to worry about．
As the discussion about the safety continues，it appears that it's best to use mobile phones less often．（35）G．Use your mobile phone only when you really need it．In the future，mobile phones may have a warning label that says they are bad for your health．So for now，it's wise not to use your mobile phone too often．

B．In many countries，cell phones are very popular with young people

8．The United States estimates that about one out of every 10 people on the planet today is at least 60 years old．By 2050，it's projected to be one out of 5．This means that not only will there be more old people，but there will be relatively fewer young people to support them．
Professor Richard Lee of the University of California at Berkeley says this aging of the world has a great effect on economics．"Population aging increases the concentration of population in the older ages and therefore it is costly，"he said．
Aging populations consume （消耗） more and produce less．With more people living longer，it could get expensive．But Mr．Lee says with continuing increases in worker productivity and smart planning，it can be manageable．
Societies have different methods for caring for the elderly，but each carries a cost．Generally，there are three types of support．Seniors can live off the wealth they gained when they were younger．They can rely on their family to take care of them，or they can rely on the government．
In industrialized nations，governments created publicly-funded （公共資助的） support systems．These worked relatively well until recent years，when aging population growth in places like the United States and Western Europe began to gradually weaken the systems'finances．These nations now face some tough choices．Mr．Lee says the elderly in some of these countries must either receive less money，retire later or increase taxes to make the system continuable．
Most developing nations haven't built this type of government-funded support，but have instead relied on families to care for their elderly．These nations also generally have a much younger population，which means their situation is not as urgent as more developed nations．But Mr．Lee says that doesn't mean they can ignore the issue．"Third World countries should give very careful thought to this process，to population aging and how it may affect their economies-now，before population aging even becomes an issue，"he explained．
29．"Aging"in this text meansD．
A．there are more young people than old people
B．a(chǎn)n increasing number of old people are dying
C．more and more young people are growing old
D．the percentage of old people in the world is increasing
30．What is Professor Richard Lee's attitude towards population aging？B
A．Indifferent．
B．Negative．
C．Optimistic．
D．Worried．
31．The publicly-funded support systems in industrialized nationsA．
A．a(chǎn)re facing the risk of failing
B．have failed to provide support for the old
C．will be replaced by other support systems
D．have greatly affected the nations'economies
32．We can infer from the text that developing nationsB．
A．don't see population aging as an issue
B．should prepare for population aging．
C．a(chǎn)re facing urgent situations of population aging
D．have better ways to deal with population aging．

15．For their nick-of-time acts，Toby，a 2-year-old dog，and Winnie，a cute cat，were named Dog and Cat of the Year by the American Society for the Prevention of Cruelty to Animals．
As Amy Paul choked（哽�。� on a piece of apple at her home，her dog jumped up，landing hard on her chest and forcing the piece in her throat out．When the Keesling family of Indiana was about to be killed by carbon monoxide，their cat clawed at the wife Cathy's hair until she woke up and called for help．
No one could explain their timely heroics．
Both pets were rescued by their owners in infancy-----Toby as a 4-week-old thrown into a garbage bin to die，and Winnie as a week-old orphan hiding under a barn，so helpless that Cathy's husband，Eric，had to feed her milk with an eyedropper．
As the Keeslings recalled it，a gas-driven pump being used broke down，spreading carbon monoxide through the house．By the time Winnie went to rescue，the couple's 14-year-old son was already unconscious．"Winnie jumped on the bed and was clawing at me，with a kind of angry sound，"Cathy Keesling said．The state police responding to her 911 call said the family was only minutes from death，judging by the amount of poisonous gas in the house．
Amy Paul's husband was at his job when she took a midday break from making jewelry and bit into an apple．"Normally I peel them，but I read in Good Housekeeping Magazine that the skin has all the nutrients，so I ate the skin，and that's what caused me to choke，"she recalled．"I couldn't breathe and I was in panic when Toby jumped on me．He never does that，but he did，and saved my life．"
Both Toby and Winnie accompanied their owners to the awards luncheon．
21．What would be the suitable title for the passage？B
