In the United States, sixteen, eighteen, and twenty-one are important ages in a person’s life. There are no special celebrations for these birthdays, but each is a time when a person can do new things to mark their transition(转变) into adulthood.
After turning sixteen a person can work, get a driver’s license and leave home. Many high school students learn to drive and get part-time jobs soon after celebrating their sixteenth birthday.
At the age of eighteen a person in the United States can vote and smoke, but they are prohibited from going into nightclubs, buying wine or gambling(赌博) until they are twenty-one.
In many Latin(拉丁的) cultures, a young woman’s fifteenth birthday is important. At this age, she is regarded as an adult. To mark this special day, families with teenage daughters have a celebration called a Quinceanera. The day begins with the young woman and her family going to church. Later, there is a party and many guests are invited.
In Japan, young people became adults at twenty. At this age, they can legally(合法地) vote, drink wine and smoke. The second Monday in January is a national holiday called “Coming of Age Day”. On this day, twenty-year-old celebrates by first going to church to pray with their families. Later, they listen to speeches given by city and school leaders. Afterward, they may celebrate with family or friends late into the night.
In some countries, birthday celebrations continue through adulthood. Some people celebrate their fortieth and fiftieth birthdays, or their retirement(退休) year, with a huge party.

答案：
(答案→)B
解析：本文讲的是在美国三个重要的人生年龄16，18和21岁，并讲了一些其它国家与庆祝生日的事情。
1.B 细节题。原文说：Many high school students learn to drive and get part-time jobs soon after celebrating their sixteenth birthday，故选开车和得到工作，B正确，vote 和smoke指的是在18岁。
2.A 文章开头就讲出了三个重要的年龄，16，18和21，故15不对，选A。
3.B 此题考查猜单词，我们应从上下文来判断。At the age of eighteen a person in the United States can vote and smoke, but they are prohibited from going into nightclubs从这句中的but可知前后两句话是转折关系，前面说18时可以选举和吸烟，故下面的prohibit是禁止的含义。
