Crime in the city of Clio hit a 30-year low last year. “This is absolutely wonderful for our citizens, our businesses, and our visitors," said Police Chief Louis Gates. Clio has a population of 28,000, but it has at least 30 gangs ( 帮派). The gangs make most of their money from dealing drugs and offering "protection.” They also commit violent crimes, such as stealing, robbery or even murder.

There were 1,486 thefts last year. Most of the thefts involved cars. Thieves also robbed the people at gunpoint or pick pocketed them. They broke .into houses and businesses at the alarming rate of two a day two years ago, but that rate was down to only one a day last year. "That's a 50-percent

decrease in one year," said Gates. "I think the police officers deserve a big pat on the back. Even better, maybe they’ll get that 10-percent raise that they are all hoping for. "

With an example of how the police force has helped reduce crime, Gates talked about bicycle thefts. "For years and years, kids were locking up their bikes at bike stands in front of schools, libraries, and shopping mails. About 10 percent of the time, the kids would come out of the school or wherever and discover that their bike was no longer there. We wracked our brains( 绞尽脑汁) trying to find a solution to this problem. Finally, at the beginning of last year, when we simply removed most of the bike stands, then the bicycle theft rate came down quickly.

Most cities in the state have similar problems. They all involve too many people, too much crime, too few police, and too little money. These problems go along with civilization everywhere. They might reduce, but they will probably never disappear. All people can do is hope for the best and prepare for the worst.

68. Crime in the city of Clio is mainly caused by _____.

A. illegal gangs    B. protection providers  C. cruel murderers    D. drug dealers

69. The underlined part in the 2nd paragraph probably means the police in Clio ____.

A. hasn’t done well in the prevention of crimes. B. is responsible for alarming rate of crimes

C. is worth praising for what they have done       D. is faced with sudden attacks from behind

70. The police force has helped reduce the bicycle theft rate by _____.

A. removing most of the bike stands          B. asking kids to lock up their bikes

C. setting up more public bike stands         D. asking kids to park their bikes in front of schools

71. The author wants to tell us that _____.

A. crimes are part of civilization in some of the cities        

B. the best will completely defeat the worst in development

C. crimes and civilization are two sides in development

D. civilization development leads to problems in cities

Americans think that travel is good for you. Some even think it can help to solve one of the coun??try ’ s worst problems ~: crime (犯罪).

Crime worries a lot of people. Every year, the number of crimes is up and up. And many criminals (罪犯)are young. They often come from sad homes, with only one parent or no parents at all.

There are many young criminals in prison,but prison doesn ’ t change them. Six or seven in ten will go back to crime when they come out of prison.

One man ,Bob Burton, thought of a new idea. In the old days, young men had to live a difficult life on the road. They learned to be strong and brave, and to help their friends to be strong and brave, and to help their friends in time of danger. This helped them grow into men. So Bob Burton started “Vision Quest. “ He takes young criminals on a long ,long journey with horses and wagons (马车), 3,000 miles through seven states. They are on the road for more than a year.

The young people in Vision Quest all have bad problems. Most of them have already spent time in prison. This is their last chance.

It's hard work on the road. The day starts before the sun comes up. The boys and girls have to feed the horses. Some of them have never loved anyone before  but they love their horses. That love can help them to live a new life.

Not all the young people on Vision Quest will leave crime behind them. Three or four in ten will one day be in prison again. Bob Burton is right. Travel can be good for you. Even today, Americans still say, “ Go west, young men. ”

In the last paragraph “leave crime behind them" means    .

A. no longer do a crime B. leave people who do a crime

C. don't do all the crimes       D. leave criminals behind

Why is Bob Burton right?

A .Because he can help to solve crime.

B .Because three or four is better than six or seven.

C .Because the young criminals have a hard life on the road.

D .Because he can stop crime in the country.

Form the passage we may infer that   .

A .getting up before the sun rises can help out of crime

B .we can hardly find a person who has no love for anybody or anything

C .travelling can help all criminals out of prison

D .young people can do anything freely

     On “ Vision Quest"   .

A. young people have bad problems

B .young people grow tall very fast

C .young people often help their friends in time of danger

D .all of the above

Americans still say, "Go west, young men. ”because .

A .if they go west they can have a travel

B .in the west there is a prison

C .there they have to live a hard life to grow into men

D .prison doesn't change them

Your cell phone holds secrets about you. Besides the names and numbers that you’ve programmed into it, traces of your DNA remain on it, according to a new study.

   DNA is genetic material that appears in every cell. Like your fingerprint, your DNA is unique to you --- unless you have an identical twin. Scientists today usually analyze DNA in blood, saliva(唾液), or hair left behind at the scene of a crime. The results often help detectives identify criminals and their victims.

   Meghan J. McFadden, a biologist at McMaster University in Hamilton, Ontario, heard about a crime in which the suspect bled onto a cell phone and later dropped the device. This made her wonder whether traces of DNA remained on cell phones --- even when no blood was involved. To find out, she and a colleague collected flip-style(翻盖式) phones from 10 volunteers. They collected invisible traces of the users from two parts of the phone: the outside, where the user holds it, and the speaker, which is placed at the user’s ear.  

   The scientists scrubbed(meaning “cleaned”) the phones using a liquid mixture made mostly of alcohol. The aim of washing was to remove all detectable traces of DNA. The owners got their phones back for another week. Then the researchers collected the phones and repeated collecting traces on each phone once more. They discovered DNA that belonged to the phone’s owner on each of the phones.

   Surprisingly, DNA showed up even in swabs that were taken immediately after the phones were cleaned. That suggests that washing won’t remove all traces of evidence from a criminal’s cell phone. So cell phones can now be added to the list of clues that can help a crime-scene investigation.

McFadden decided to find out whether people leave their DNA on their cell phones when she ____ .

       A. got her cell phone lost by chance        

       B. found a cell phone with blood on it

       C. heard about a crime involving a cell phone 

       D. did research on cell phones

The scientists allowed the volunteers to keep their cell phones for a week in order to____.

      A. let them leave their traces on their phones 

              B. avoid keeping their cell phones too long

              C. give them a chance to get rid of their secrets

              D. find out who is responsible for the crime

The last paragraph mainly tells us that cell phones ____ .

              A. do harm to people  B. should be often cleaned

              C. disclose people’s secrets       D. help deal with crimes

Which of the following is NOT mentioned in the passage?

              A. The reason for collecting the phones from volunteers.

      B. The technique of collecting DNA on the phones.

      C. The method of removing traces of DNA on the phones.

      D. The purpose of washing the cell phones.
