2．In our daily life，it is necessary to make small talk in certain situations．It helps to fill time between people when it is completely quiet．You may not feel like talking with someone else or you are very shy at the beginning，but it is sometimes thought to be rude to say nothing．
People use small talk almost every day．It usually takes place when you meet someone you don't know at all or someone you're not familiar with．For example，waitresses and hairdressers often make small talk with their customers．If you happen to be outside when the mailman comes to your door，you might make small talk with him，too．
Most often，small talk happens in places where people are waiting for something．For example，you might talk with another person who is waiting for the bus to arrive．People also make small talk in a doctor's waiting room，or when they are waiting in a line to buy something．At the office，people make small talk in elevators or lunchrooms，especially if there is a line-up．Mingling（交際） is often required among people who don't know each other very well at a party．In other words，they are expected to walk around and talk with othe rs．
The most common time for small talk to happen is the first time you see or meet someone on a given day．For example，if you see a co-worker in the lounge （休息室） you might say hello and discuss the sports or weather．However，the next time you see each other you might just smile and say nothing．If there is very little noise，it might be the right time to start a pleasant conversation．If someone is reading a book at the bus stop，it is probably not a good idea to start a conversation．Another good time to make small talk is during a break in a meeting when there is nothing important going on．However，it is important to recognize the signal when the other person wants the conversation to stop．

17．A strange，new dilemma faces Chinese pedestrians：should you help an elderly person who has fallen into the street？The answer seems simple．Your conscience forces you to help someone in danger．But many Chinese are discovering that some of these injured people are scammers．They accuse good Samaritans（好心人） of having knocked them over in the first place，and they file complaints in hopes of receiving large amounts of compensation．
There are frequent reports on such incidents and following disputes．On Sept 8，a new case happened in Huainan，Anhui province．Yuan Chen，a 20-year-old college student from Huainan Normal University，claimed that she helped an injured elderly woman on the street．But the woman's family has demanded that Yuan take full responsibilities for the injuries．
Since the incident happened in the security cameras'blind spot，both sides are looking for witnesses to clear their names．The local police department is also investigating the case．But how can you possibly solve a case like this，where the only evidence comes from two conflicting viewpoints？
"This kind of cases should follow the principle of‘the burden of proof lies with the person making the claim'，"Ye Lin，a law professor from Renmin University of China，told China Central Television．The burden of proof means the collection of proof or evidence．In civil cases，"if you accuse someone of causing you harm or losses，you should collect convincing proof to back your claim，"said Ye．"If you cannot do that，the law will not be able to support your claim．"
The law may not resolve all the problems，however．Some elderly people choose to blackmail（敲詐） their helpers because they do not have health insurance．To prevent this，the country needs to put in place a better social security net．

12．Which of the following statements is TRUE according to the first paragraph？B
A．Conscience is troublesome because it compels you to help someone who will set you up in return．
B．Sometimes the warm-hearted are wrongly accused of having knocked others over．
C．It is advisable for Chinese people to turn a blind eye to someone in danger．
D．There's no doubt that the elderly usually fell down on purpose to claim compensation．
13．What does the sentence in paragraph 3"both sides are looking for witnesses to clear their names"mean？D
A．Both sides are in search of someone who can call out their names．
B．Both sides are in search of evidence that can clarify their opinions．
C．Both sides are in search of evidence that can wash away their crimes．
D．Both sides are in search of someone who can prove they are telling the truth．
14．What can we infer from Ye Lin，the law professor's words？C
A．Ye Lin thinks it is Yuan Chen who is responsible for gathering proof．
B．In civil cases，the accused should collect proof as well to reject the claim．
C．The principle regards the accused as innocent until convincing proof can be provided．
D．Since it is hard to collect convincing proof，both sides should take on the responsibility．
15．What is most likely to be written in the paragraph that follows？B
A．To make comments on this hot social phenomenon．
B．To emphasize the necessity of an improved social security system．
C．To analyze deep causes of the elderly blackmailing their helpers．
D．To illustrate the impact brought about by the blackmail on our society．

1．America is growing older．For fifty years，only 4 out of every 100 people in the United States were 65 or older．Today，10 out of every 100 Americans are over 65．The aging of the populations will affect aspects of society-education，medicine，housing，and business．The graying of American has made us a very different society-one in which people have quite a different perception （認(rèn)識(shí)） of what kind of behavior is proper at various ages．
An adult's age no longer tells you anything about that person's economic or marital status （婚姻狀況），lifestyle，or health．There's no longer a particular year，or even a particular decade，in which one gets married or goes to work or goes to school or has children．The social clock that kept us on time and told us when to get married，to school，get a job，or retire isn't as strong as it used to be．It doesn't surprise us to hear of a 29-year-old university president or a 35-year-old grandmother or a 70-year-old man who has become a father for the first time．Public attitudes are changing．
Many people say，"I am much younger than my mother or my father was at my age．"No one says，"Act your age，"anymore．We've stopped looking with disagreement at older people who act in youthful ways．
13．The best explanation of the expression"acting your age"isB．
A．a(chǎn)cting a part of a play when you are old enough
B．doing the things that people expect you of your age to do
C．playing an important role in the society when you are grown up
D．working hard and supporting the family when you are an adult
14．According to the passage，the population in America is getting older，which will affect all of the following exceptB？
A．ho using and business  
B．birth rate     
C．medicine            
D．education
15．Choose the best one to complete the sentence"An adult's age used to tell people something about what person'sD．"
A．schooling and interest  
B．family and housing
C．a(chǎn)bility to so something  
D．health，lifestyle，economic or marital status．
