four great reasons for high school students to volunteer

Volunteer work presents a great opportunity for teenagers to prepare for the future, as well as to improve their communities. In addition to boosting socializing skills and awareness of local organizations and social issues, high school students who volunteer often may have an advantage over their peers when headed off to college.

1. Gaining New Skills

With each new volunteer activity, students gain new skills. The skills seem to be basic or trivial at the time of training, but may provide fundamental grounds for future success. For example, For example, by managing the receipt, sorting and distributing the donations from community, school students might learn how to use spreadsheets to keep track of inventory. These skills are a great foundation for a job in management, accounting, or running a small business.

2. Giving Time

One of the most charitable acts anyone can do is donate their time and talents. Students who are busy with after-school sports or work to help support their families and still make time to volunteer on evenings or weekends show their outstanding character and resolve to make a difference. High school students may help to mentor younger ones or to assist with one-time special events held on weekends.

3. Showing Responsibility

Just like going to a job, committing to a volunteer position shows a student's responsibility. High school students should get involved in volunteer programs relating to their hobbies in order to naturally build responsibility. For example, those who love to read can find volunteer opportunities with a local library and those who enjoy sports can coach athletics at an after-school program for children.

4. Adding to the Resume

If a high school student's pre-college resume is limited to summer employment at a local restaurant or a cafe. it might be time to add a few lines. Commitment to community volunteer work over a long time shows that a student is willing to work for something without monetary compensation, including a college internship or apprenticeship, which may be a requirement of college programs.

1. According to the passage, who is volunteer work beneficial to?

A. high school students

B. students' communities

C. both students and communities

D. none of them

2. The word 'trivial' in paragraph 2 most closely means ________

A. important

B. significant

C. of little importance

D. fundamental

3. According to the passage, what job will the students' skill of using spreadsheets be useful to?

A. a manager

B. an accountant

C. a business owner

D. all of them

4. Why should busy students make their time to volunteer?

A. to demonstrate their excellent quality

B. to show their outstanding outcomes

C. to support their families

D. to develop their talents

5. According to the passage, what volunteer programs help to develop students' responsibility?

A. The programs are related to their future jobs

B. The programs are related to their interests

C. The programs are available after school

D. The programs are held by their local library

6. What volunteer work may be suitable for a student who likes sports?

A. working in a local library

B. joining a football team in their school

C. being a sport instructor at a primary school

D. coaching a football program for children after school hours

7. The phrase 'it might be time to add a few lines' in paragraph 5 most closely means________

A. Some more lines should be added in your resume

B. Much volunteer work must be included in your resume

C. You might spend more time to write your resume

D. Your resume should include your experience in volunteering

8. What may be a requirement of college programs for their future students?

A. being able to work over time

B. agreeing to work as a paid apprentice

C. being willing to work without being paid

D. being employed before

III. Read the text and decide whether the sentences are true (T) or false (F)

USAID IN Vietnam

Assisting persons with disabilities has long been one of the top priorities for the U.S. Government in Vietnam. Since 1989, with the establishment of the U.S. Agency for International Development’s (USAID) Leahy War Victims Fund (LWVF), USAID is working to increase the availability of and access to a wide variety of programs benefiting people with disabilities in conflict-affected countries.

In Vietnam, U. S. assistance has helped address medical needs and support the inclusion of Vietnamese with disabilities into all aspects of society. The U.S. Government has contributed more than $80 million in assistance to persons with disabilities, has improved the lives of more than 30,000 persons with disabilities, and has strengthened the Government of Vietnam’s capacity to provide high quality services to those in need. USAID has provided rehabilitation services for tens of thousands of persons with disabilities, education and vocational training including information technology, job placement, supporting parent associations to expand the advocacy for disability issues, and support for the development of legal codes to improve physical accessibility for persons with disabilities in public buildings.

USAID'S work supporting persons with disabilities is also viewed by many as contributing to successful US-Vietnam cooperation to overcome the painful past shared by the two countries. Program activities work in three areas: policy advocacy and coordination, direct assistance including occupational and physical therapy and providing assistive devices, and health systems strengthening, to provide quality disabilities-related care and treatment. Persons with disabilities have been more readily integrated into society by improving their access to health, education and social services. USAID programs support local governments in implementing the national disability law and the U.N. Convention on the rights of Persons with disabilities, and influencing public policies that affect the lives of persons with disabilities.

1. USAID was established in 1989 _____

2. USAID aims to make various programs benefiting all people in conflict-affected countries ___________

3. Addressing medical needs of Vietnamese people is the priority of U.S assistance in Vietnam ___________

4. American government has made an $80 million contribution to help disabled people in Vietnam __________

5. Thanks to USAID, more high quality services are provided to disabled people in Vietnam __________

6. USAID has helped to rehabilitate only a limited number of persons with disabilities in Vietnam __________

7. USAID work makes a great contribution to the success of US-Vietnam cooperation ___________

8. The main focus of USAID activities is providing direct assistance with occupation replacement and health treatment for the disabled. ___________

9. Having better access to health, education and social services, the disabled in Vietnam have become more integrated into society ___________

10. Thanks to USAID programs, the Vietnam's national disability law and the U.N. Convention on the Rights of persons with disabilities have been enforced ___________

University Entrance Examination is very important to Vietnamese students. High school graduates have to take it and get high results to be admitted to universities. The pressure on the candidates remains very high despite the measures that have been taken to reduce the heat around these exams, since securing a place in a state university is considered a major step towards a successful career for young people, especially those from rural areas or disadvantaged families. In the year 2004, it was estimated that nearly 1 million Vietnamese students took the University Entrance Examination, but on average only 1 out of 5 candidates succeeded. Normally, candidates take 3 exam subjects, and each lasts 180 minutes for the fixed group of subjects they choose. There are 4 fixed groups of subjects: Group A: Mathematics, Physics, and Chemistry; Group B: Mathematics, Chemistry and Biology; Group C: Literature, History, and Geography; Group D: Literature, Foreign Language, and Mathematics.

In addition to universities, there are community colleges, art and technology institutes, professional secondary schools, and vocational schools which offer degrees or certificates from a-few-month to 2-year courses.

According to Vietnam’s Ministry of Education and Training, there are currently 23 non-public universities, accounting for 11% of the total number of universities. These non-public universities are currently training 119,464 students or 11.7% of the total number of students. The government is planning to increase the number of non-public universities to 30% by 2007.

Question. The word “non-public” can be replaced by ______

A. state

B. goverment

C. dependent

D. private

Energy makes change; it does things for us. It moves cars along the road and boats over the water. It bakes a cake in the oven and keeps ice frozen in the freezer. It plays our favourite songs on the radio and lights our homes. Energy makes our bodies grow and allows our minds to think. Scientists define energy as the ability to do work. People have learned how to change energy from one from one form to another so that we can do work more easily and live more comfortably.

All forms of energy are stored in different ways, in the energy sources that we use every day. These sources are divided into two groups – renewable and nonrenewable. Renewable energy source is an energy source that can be replenished in a short period of time. Nonrenewable energy source is an energy source that we are using up and cannot recreate in a short period of time.

Renewable energy sources include solar energy, which comes from the Sun and can be turned into electricity and heat. Wind, geothermal energy from inside the Earth, biomass from plants, and hydropower and ocean energy from water are also renewable energy sources.

However, we get most of our energy from nonrenewable energy sources, which include the fossil fuels – oil, natural gas, and coal. They’re called fossil fuels because they were formed over millions and millions of years by the action of heat from the Earth’s core and pressure from rock and soil on the remains of dead plants and animals. Another nonrenewable energy source is the element uranium, whose atoms we split (through a process called nuclear fission) to create heat and ultimately electricity.

Question Nonrenewable energy source is an energy source that can be replenished in a short period of time and renewable energy source is an energy source that we are using up and cannot recreate in a short period of time.

A. True

B. False

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions.

Animation traditionally is done by hand-drawing or painting successive frame of an object, each slightly different than the proceeding frame. In computer animation, although the computer may be the one to draw the different frames, in most cases the artist will draw the beginning and ending frames and the computer will produce the drawings between the first and the last drawing. This is generally referred to as computer-assisted animation, because the computer is more of a helper than an originator.

In full computer animation, complex mathematical formulas are used to produce the final sequences of pictures. These formulas operate on extensive databases of numbers that defines the objects in the pictures as they exist in mathematical space. The database consists of endpoints, and color and intensity information. Highly trained professionals are needed to produce such effects because animation that obtains high degrees of realism involves computer techniques from three-dimensional transformation, shading, and curvatures.

High-tech computer animation for film involves very expensive computer systems along with special color terminals or frame buffers. The frame buffer is nothing more than a giant image memory for viewing a single frame. It temporarily holds the image for display on the screen.

A camera can be used to film directly from the computer’s display screen, but for the highest quality images possible, expensive film recorders are used. The computer computers the positions and colors for the figures in the picture, and sends this information to the recorder, which captures it on film. Sometimes, however, the images are stored on a large magnetic disk before being sent to the recorder. Once this process is completed, it is replaced for the next frame. When the entire sequence has been recorded on the film, the film must be developed before the animation can be viewed. If the entire sequence does not seem right, the motions must be corrected, recomputed, redisplayed, and rerecorded. This approach can be very expensive and time – consuming. Often, computer-animation companies first do motion tests with simple computer-generated line drawings before selling their computers to the task of calculating the high-resolution, realistic-looking images.

Question. According to the passage, the positions and colors of the figures in high-tech animation are determined by _________

A. drawing several versions

B. enlarging one frame at a lime

C. analyzing the sequence from different angles

D. using computer calculations

Every four years people all over the world watch the Olympic Games. It is a time for all kinds of people to unite in peace. Some of them join together to compete for gold medals. Millions of other people watch them on television.

Why do we have the Olympic? How did they begin?

The first Olympic Games were in Greece in 776 B.C. There was only one event. People ran a nice the length of the stadium. The Games lasted one day.

Slowly people added more events. The Games were only for men, and women could not even watch them. Only Greeks competed. They came from all parts of the Greek world. The time of the Games way; a time of peace, and government let everyone travel safely. The winners became national heroes.

The first modem Games were in 1896 in Athens. The Greeks built a new stadium for the competition. Athletes from several countries competed. Then there were Olympics every four years in different cities in Europe and the United States until 1952. After that they were in Melbourne, Tokyo, Mexico City, and Montreal besides in European cities. Each year there were athletes from more nations. The first Winter Olympics were in 1924. The athletes compete in skiing and other winter sports.

Where were the cities where the Olympics were held between 1896 and 1952?

A. In European and South American countries.

B. In European countries only.

C. In European countries and the United States.

D. In Japan, Australia and North American and European countries

Read the following passage and mark the letter A, B, C, or D to indicate the correct answer to each of the questions.

In American, although most men still do less housework than their wives, that gap has been halved since the 1960s. Today, 41 per cent of couples say they share childcare equally, compared with 25 percent in 1985. Men's greater involvement at home is good for their relationships with their spouses, and also good for their children. Hands-on fathers make better parents than men who let their wives do all the nurturing and childcare. They raise sons who are more expressive and daughters who are more likely to do well in school - especially in math and science.

In 1900, life expectancy in the United States was 47 years, and only four per cent of the population was 65 or older. Today, life expectancy is 76 years, and by 2025, it is estimated about 20 per cent of the U.S. population will be 65 or older. For the first time, a generation of adults must plan for the needs of both their parents and their children. Most Americans are responding with remarkable grace. One in four households gives the equivalent of a full day a week or more in unpaid care to an aging relative, and more than half say they expect to do so in the next 10 years. Older people are less likely to be impoverished or incapacitated by illness than in the past, and have more opportunity to develop a relationship with their grandchildren.

Even some of the choices that worry people the most are turning out to be manageable. Divorce rates are likely to remain high, and in many cases marital breakdown causes serious problems for both adults and kids. Yet when parents minimize conflict, family bonds can be maintained. And many families are doing this. More non-custodial parents are staying in touch with their children. Child-support receipts are rising. A lower proportion of children from divorced families are exhibiting problems than in earlier decades. And stepfamilies are learning to maximize children's access to supportive adults rather than cutting them off from one side of the family.

Question 2. Nowadays, ____ of men help take care of children.

A. 50%

B. 41%

C. 25%

D. 20%
