Sometimes vaccines(疫苗) do not provide lifetime immunity(免疫). Some are only effective(有效)for a limited amount of time. In such cases, shots are necessary to maintain continuous vaccine protection. These shots are given at regular time. One vaccine, the flu (流感)vaccine, must be given every year. This is because there are many kinds of the flu.

A vaccine given in one year may provide protection against certain kinds of the flu virus, but when the next year’s flu season starts, vaccination against newer or different kinds may be required. Furthermore, flu vaccines do not provide protection for a lifetime. After as little as one year, protection may be far less than enough.

Music is different from songs. Songs express feelings with lyrics(歌词), but music with tones (音调).Unlike songs, music tones in themselves have no specific meanings. Different people may get different things from the same musical performance. Though some music works are difficult to understand, people need music in their daily life because it brings fun to them. Different people like different music: some love classical music, and others take an interest in pop music. Most young people like pop music.

Pop music began in the USA and became popular around the world during the 1950s and 1960s.The best-known early kind of pop music was “rock and roll”. Pop music has taken the place of (取代)native music in many parts of the world. It has caused the number of people for “jazz” music to become much smaller than in the 1950s and earlier and it has now begun to become the most popular. Much pop music is without artistic value (艺术价值), but the works of some pop singers such as the Beatles, Bob Dylan, the groups like Pink Floyd and Crosby are excellent.

Takashi is 99 years old. He lives in Okinawa (冲绳县) in Japan. In Okinawa people tend to live a very long time. They are seldom ill. Many people are over 100 years old—longer than most people in other parts of the country and the world. What is their secret (秘密)?

The Okinawans eat vegetables, fruit, fish and rice. They usually have seven different kinds of fruit and vegetables every day. People don’t usually drink much alcohol (酒) or smoke. They don’t eat much meat or fast food.

Sports are very important for the people of Okinawa. Walking, traditional dancing, and gardening are very popular with people of all ages. More important, the people in Okinawa are seldom worried or angry and they never make themselves too busy. They are relaxed and take their time. Buses often come late, and people often arrive an hour late for meetings. Every evening hundreds of people, young and old, go to the beach to watch the beautiful sunset (日落). They talk, smile or laugh to each other.

Another important thing is that people often work until they are 80, sometimes even until 90! In the Okinawan words there is no word for “out of work”. Old people don’t stay at home— they go out and meet friends.
