If you want to grow, one important thing you should do is keeping a journal. It may seem simple, but it can make a big difference in your life. I have been keeping journals for years.

科目：高中英語(yǔ) 來(lái)源：2014-2015學(xué)年甘肅武威第五中學(xué)高三11月月考英語(yǔ)試卷（解析版） 題型：閱讀理解

The parents of a troubled teen may feel unsure as to whom to turn to in order to find help for their child. They may feel as if they have exhausted all of their options, and sometimes they are on the verge of giving up. But there is hope. Schools for troubled teens offer discipline and in some cases, drug treatment programs that can provide important life skills, and more importantly, a fresh start.

The following is a list of the most effective types of schools for troubled teens. Not every facility is a match for every child, but by knowing the differences between them, parents can make a better educated decision about where to send their teenager.

Boarding Schools

When a child is unable to deal with the relative freedom of a standard school day, boarding schools might be a good choice. At boarding schools, the child lives in a dorm setting, where almost every minute of the day is scheduled by school administrators.

Treatment Centers

When a teenager has an addiction to drugs or alcohol, a residential center that specializes in young people is an outstanding way to help them break the cycle of addiction. Treatment centers feature individual and group counseling to help identify the root causes of the drug problem and help develop the life skills needed to stay clean when the program is over.

Wilderness Programs

Designed to help improve the discipline and self-reliance of the child, wilderness programs send kids back to nature. By placing them in a foreign and sometimes uncomfortable setting, wilderness programs hope to improve children’s behavior. Programs generally include hikes, exercise programs and team building exercises.

Boot Camps

Boot camps are the most extreme style of school for troubled teens. These facilities are modeled after actual military boot camps, where the individual must get into shape, work as part of a team, and follow a long, hard set of rules and regulations. However, boot camps might not be the best choice for a teen with a drug addiction.

1.Who would be the intended readers of the passage?

A. Teachers. B. Parents.

C. Students. D. Experts.

2.As the author suggests, schools for troubled teens______.

A. can be a good choice for some desperate parents

B. can completely help and change troubled teens

C. are becoming popular with teens in trouble

D. care more about discipline than life skills

3.According to the passage, boarding schools_____.

A. provide children with more freedom

B. have their students’ time managed carefully

C. pay much attention to team building exercises

D. can make children feel safer

The Horn of Plenty is one of the largest natural health food stores within the Greater Hamilton area. We are big supporters of buying locally and we are here to tell you why it is so important for your family, the community and the environment.

The concept of buying locally is simple: buy food produced, grown, or raised as close to your home as possible. Not only will your food be fresher and tastier, but you are helping protect the environment and are supporting businesses within your community and reducing pollution.

Better for the environment

Sustainability (持續(xù)性) and global warming are such hot topics at the moment, and many people want to do their bit to help support a healthier environment. Small action carried out by many people can make a big difference. Most materials in an average North American meal have traveled about 1,500 miles to get from farm to plate. To cut out a big part of this travel would greatly reduce not only pollution from transportation and refrigeration but also customers’ expenses as well.

Taste and nutritional content

Locally-grown fruits and vegetables are usually sold within 24 hours of being harvested. Because they are picked at the height of ripeness (成熟) and travel only a short distance to the market, their freshness, nutrition, and flavor are kept. Produce trucked in from far away may lose both taste and nutritional content.

Community and home values

When you buy direct from a farmer or buy locally-grown foods, you are engaged in a time-honored tradition between a grower and an eater. You also help keep dollars within your community.

1.It can be inferred from the third paragraph that ___________.

A. global warming is the most serious problem now

B. North American food is rich in various kinds of materials

C. the increased cost of transporting food is passed on to the customers

D. most people support buying locally

2. Locally-grown fruits and vegetables taste good mostly because___________.

A. they are picked when they are fully grown

B. they are not polluted by chemical fertilizer

C. they can be harvested at any time

D. they are sent to the market at a high speed

3.According to the author, when you buy locally-grown foods ___________.

A. you can see how fruits and vegetables grow

B. you will contribute to protecting the environment

C. you will become much healthier and prettier

D. you are making money from your community

4.What does the passage mainly talk about?

A. The way to keep your food tasty and healthy.

B. The popularity of the Horn of Plenty.

C. The importance of protecting the environment.

D. The benefits of buying locally.
