Prevention is better than cure. This saying has never been more appropriate than with reference to vaccination (接种疫苗). There are two main types of vaccines—live vaccines and killed or inactivated vaccines. Live vaccines are vaccines that contain disease causing antigens which are altered in such a way that weakens them to the point that they're no longer able to cause the disease. Killed or inactivated vaccines contain microbes (细菌) that have already been treated by chemical means to prevent them from copying or causing diseases. This means that any kind of vaccine for children cannot produce diseases, but can only help the body in creating antibodies that prevent that particular disease.
For a vaccine to make it to the market, its safety has to be confirmed. So most vaccinations for children are generally quite safe and are essential to children's health.
Vaccination can create immunity to various childhood diseases through deliberate artificial stimulation of the body's defenses. Among children, vaccinations not only prevent diseases and disorders, but also protect the health of the community, especially of those who aren't immunized (使免疫). For example, infants that are less than a year old cannot be given a measles (麻疹疫苗) vaccine but can be infected by measles. This can be prevented if people suitable for vaccination do get themselves vaccinated.
However, no vaccination is hundred percent safe, and there're always certain risks involved in vaccinations for children. For example, general side effects like pain, redness, headaches, swelling or a small lump at the site of the injection are common. Sometimes allergic (过敏) reactions may happen as well.
Therefore, when choosing any vaccination, parents should make an informed decision by weighing all pros and cons of vaccination for children. After all, the side effects of vaccines for children are far less severe, when compared to the symptoms of the diseases they prevent!

World Health Day is celebrated on 7 April to mark the anniversary of the founding of WHO in 1948. Each year a theme is selected for World Health Day that highlights a priority area of public health concern in the world.
The theme for 2013 is high blood pressure. High blood pressure increases the risk of heart attacks, strokes(中风). If left uncontrolled, high blood pressure can also cause blindness, irregularities of the heartbeat and heart failure. The risk of developing these complications is higher in the presence of other risk factors such as diabetes(糖尿病). One in three adults worldwide has high blood pressure and this increases with age, from 1 in 10 people in their 20s and 30s to 5 in 10 people in their 50s. High blood pressure is most common in some low-income countries in Africa, with over 40% of adults in many African countries thought to be affected.
However, high blood pressure is both preventable and treatable. In some developed countries, prevention and treatment of it has brought about a reduction in deaths from heart disease. The risk of developing high blood pressure can be reduced by: reducing salt intake; eating a balanced diet; avoiding harmful use of alcohol; taking regular physical activity; keeping a healthy body weight; and avoiding tobacco use.
The final and most important goal of World Health Day 2013 is to reduce heart attacks and strokes, which includes as follows:
1.to raise awareness of the causes and consequences of high blood pressure;

第一节 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，并在答题卡上将该项涂黑。（共20小题；每小题2分，满分40分）
Most American colleges
and universities take a spring break. Students might go home to their families
-- or spend a week partying on a warm beach with no parents around. That is the
popular image, at least.
In the United States, the lawful age to drink alcohol is twenty-one -- one of the highest in the world. Americans debate whether it should be lowered, or whether young drinkers would only drink more. In parts of Europe, the lawful drinking age for beer, and sometimes hard liquor, is sixteen. Yet France may raise the age limit for beer and wine sales to eighteen, the same as for hard liquor there.
Rules on alcohol differ from college to college in the United States. Many schools require all first-year students to take an alcohol prevention and education program, often given online. Some have a “zero tolerance” policy where alcohol is banned from all buildings. Parents are informed of violations and students may be suspended(停学).
At the University of Virginia in Charlottesville, permission is needed to serve alcohol at any event on campus. But alcohol is banned in first-year dorms---where most students are under twenty-one anyway.
Susan Davis, a
university lawyer, says campus police and local police report underage drinking
violations(违反)to the committee that decides punishments on a
case by case basis. For example, the committee might suspend or expel(开除)a
student. It might require an alcohol education program. Or it might just give a
warning.
Jon Zug is a lawyer in Albemarle County, where the university is located. He says international students would face the same punishment as American citizens for underage drinking in Virginia. That includes a punishment of five hundred dollars or fifty hours of community service. But first law-breakers might be given a chance to complete an alcohol education program instead.
Schools have to report unlawful violations by international students to the Department of Homeland Security. International adviser Richard Tanson at the University of Virginia says even minor violations stay on a student’s permanent immigration record. He says international students should know that this can affect them in the future if they try to re-enter the United States.
1. What does the underlined phrase “by case basis” mean?
A. Depending on the seriousness of the case itself.
B. According to the report of the campus and local police.
C. Depending on the judgment of the committee.
D. According to the former cases in store.
2. To international students, which of the following may be intolerable once they have drinking violations?
A. A punishment of $500 or 50 hours of community service.
B. Being given a warning of being suspended or expelled.
C. Having the violations kept on their permanent immigration record.
D. Receiving an alcohol education program.
3. The passage probably appears in_________.
A. an advertisement B. a local newspaper
C. a university guide book D. a popular magazine
4. The passage mainly talks about_________.
A. alcohol problems on the U.S. campus
B. alcohol policy on U.S. campus
C. U.S. universities---zero tolerance to alcohol
D. the punishment to the university alcohol drinkers
