6．The police find most criminals because somebody tells them who the criminals are．They find other c——青夏教育精英家教网——

6．The police find most criminals （罪犯） because somebody tells them who the criminals are．They find other criminals by using science and their computers．When there is a bank robbery （抢劫），the police first look through their computers for the names of the bank robbers that they know about．Then they go and talk to any of these robbers who are not in prison （监狱）．They ask them where they were when the robbery happened．If any of these people cannot give a good answer，the police will often use science to find out if one of them is the robber．
Many criminals leave something of themselves at the places of the crimes like a fingerprint or a hair．Or they take something away on their shoes or clothes，like dirt or animal hair．If they leave behind some of their blood or their hair or a piece of skin，it will have their DNA inside it．
Everyone's DNA is different and their fingerprints are also different．So，if a criminal cuts himself during a robbery or leaves his hair，or even a small piece of skin，scientists can find out what his DNA is．The police can then ask the person they think is the robber to give them his hair or some blood and see if it has the same DNA．Many criminals are in prison today because of this kind of evidences．

Liu Xu was robbed（抢劫）!The 13-year-old was riding home when a man jumped out from the road-side．He pulled Liu off his bike and rode away．Liu was scared，but he didn't run after the robber．He found a telephone and called the police at 110．
"Safety is the first in such a situation，"Liu said，remembering what his teacher had told him in his aid class．"It's not safe to run after an adult who is much stronger than you．"
Liu is a student at Shenzhen Bao'an Middle School in Guangdong．His school is one of the first in China to have required first aid education．Grade 1 students must take the class once a week．
Teenage safety has become a serious problem recently．According to a recent survey，about 16，000 teenagers die in accidents in China every year．An average（平均） of 40 students die every day from drowning（溺水），food poisoning（中毒） and traffic accidents．
Bao'an School said that the first aid classes are to"teach students skills so that they can keep themselves safe and save themselves from danger．"
Students at Bao'an often learn by role（角色）-playing in first aid classes．
Zhou Min，12，remembered her favorite lesson．"I performed as a stranger knocking at a door．A classmate stood inside the door and asked several questions before letting me in．Then we changed roles and did it again，"Zhou said．"We learned a lot while having fun at role-playing．"
The topics of the class are regularly changed．The students have learned skills for life saving in earthquakes．They also deal with topics like sexual harassment（骚扰）．
"The teacher told us girls that we should try not to go out alone，especially at night．If someone tries to do bad things to us，we may hit their eyes or noses or kick their deadly parts．Then we should quickly run into a crowded place，"said Zhong Hua，a 13-year-old girl．

1．阅读下列短文，从每题所给的四个选项（A、B、C和D）中选出最佳选项．

1 I've been working as a professional clown（小丑）for nearly two years．Before that，I was an actor for nine years．I was never famous，but I was quite successful!I changed jobs because I wanted to do more in life than make people laugh．What if I could help people，too？
As a clown，I try to encourage sick chileren in hospital to laugh and smile．When you laugh，your mind and body relax．Clearly，people who laugh more don't have as many colds or other problems!Children who laugh a lot often get better results in their studies，too．
It isn't an easy job．Not all sick children get better，and sometimes I come home and cry．But I always go back to work the next day with my red nose on．I don't earn much money as a clown，but I feel very lucky to work with such brave，wonderful patients．

2 I became a laughter yoga（瑜伽）teacher more than two years ago．Before that，I was a dentist!My job was very difficult，and I used to feel fed up．Now I still improve people's health，but everything else is completely different．Everyone has fun in a laughter yoga class，including the teacher!
No，laughter isn't"magic"．It doesn't prevent all illness，keep you young，or make you beautiful．But did you know that is't an excellent kind of exercise？You move your whole body when you laugh!
Sometimes I worked with famous people．It's true that being rich can be stressful!Some famous people can be unpleasant at times，but I try to change their bad feelings．Laughter is excellent for people like musicians，artists and writers，because it helps people to be more creative．
