4. In the United States today there are more than half a million criminals serving time in prison. Most prisoners are male high-school dropouts between the ages of 18 and 19. Even more shocking in the fact that the number and rate of imprisonment has more than doubled over the past twenty years, and the recidivism - that is, the rate for rearrest - is more than 60 percent.

Although the stated goal of most prison systems, on both federal and state levels, is to rehabiliatate the inmates and reintagrate them into society, the systems themselves do not support such a result. Prisons are usually geographically or psychologically isolated and terribly overcrowded. Even in the more enlightened prisons, only one-third of the inmates have vocational training opportunities or work release options.

If prisons are indeed to achieve the goal of rehabilitating offenders, then the prisons themselves will have to change. First, they will have to be smaller, housing no more than five hundred prisoners. Second, they will have to be built in or near population centers with community resources available for gradual reintegration into society. Finally, prison programs must be restructured to include work release and vocational and academic training that promises carry over into the inmate’s life after release. Models for such collaborative efforts between the criminal justice system and the community already exist in several hundred half-way houses throughout the country.

1. What is the author’s main point?

A. Prisons must be restructured if they are to accomplish the goal of rehabilitation.

B. Models for community collaboration have been successful.

C. Most of the criminals serving time in prison are high-school dropouts.

D. The criminal justice system must establish a better goal.

2. According to the author, how many prisoners are offered training or work release?

A. None B. 33.33 percent C. 50 percent D. 60 percent

3. The author mentions all the following as necessary to prison reform EXCEPT

A. newer buildings C. vocational training

B. smaller institutions D.collaboration with the community

4. The word “recidicism” in line 4 refers to

A. all people who are imprisoned C. people who drop out of high school

B. people who return to prison after release D. people who have been in prison for a long time

5. The paragraph following this passage most probably discusses

A. the goals of most state and federal prisons

B. the cost of prison reform

C. examples of models for community collaboration

D. problems with the current criminal justice system

II. Read the text and answer the questions.

Teenagers today are undergoing lots of changes. They are between the ages of 13 to 19. Many of them are undergoing physical and emotional changes. These are the stages in the teenagers that are unavoidable.

The teenage life is full of happiness, sadness, enjoyment and it can be interesting too. This is because in the teenage life that a teenager is subjected to physical growth, hormonal changes and even dilemmas. They may be in a stage of conflict like undergoing puppy love. This is only a normal part of life.

Making friends is part and parcel of a teenager's life. The teenager should enjoy life by making friends with peers and participate in healthy activities such as camping, picnic, kayaking, swimming and so on. Through friends, a teenager learns to joke, laugh and play to release stress and tension. By making friends, the teenager learns to sweeten his or her joys and even eases the bitterness of life's downtime.

Many teenagers are very conscious of their physical outlook. It is at this part of their life that beauty strikes as the main self-image. They love to follow up with the latest trends for dressing, hairstyle and even look good with their physical image. Some girls and boys go on a crash diet to slim down in order to look attractive. Others may suffer from acne and pimples that may scar their external beauty.

Another stage in a teenager is the teenager's love life. There are chemical changes in the body and so the teenager tends to have a sense of feelings for the opposite sex. They will experience love and rejection. These sometimes will affect their studies.

Parents tend to play a role in a teenager's life. Parents today are overly concern over their children's well-being. They like to control their freedom and have a say what the teenagers do. Hence, we have cases of disagreements, disputes, quarrels and even runaways from homes among some teenage girls.

There are also negative problems that may pop out during a teenage life. A teenager is not well guided may fall into the wrong path. Some teenagers are involved in drugs trafflicking, smoking, drinking and smuggling of illegal products into the country. Others tend to vent their anger by vandalizing public property. We have those with no regard and respect for the elders.

The mass media has an influence over the lives of many teenagers. Violent action movies, obscene shows and pornography surfed from the Internet can bring a disastrous effect on a teenager's life. There will be more harm than good if nothing is done.

1. From paragraph 1

(a) What is the age range of a teenager?

(b) What are the changes that a teenager undergoes?

2. From paragraph 2

(a) Why is it that a teenage life is full of ups and downs?

(b) What kind of conflict does a teenage face?

3. From paragraph 3

List activities that a teenager can get involved in.

4. From paragraph 4
