【答案】

The most serious environmental problem

—global warming

There are many big environmental problems facing us on the earth today, but I think the most serious one is global warming. Global warming means an average increase in the earth’s temperature. It is caused by gases from cars, waste gases from factories, destruction of forests, and so on. Global warming will cause changes in climate. A warmer earth may lead to more rain and the rising of the sea level. In this case, some land will be flooded and also it will have a bad influence on both human beings and wildlife.

So, how to solve the problem of global warming is really urgent for human beings. What can we do? First of all, people should be educated to raise the awareness of environmental protection. Also, we should call for people to take action and encourage people to use bicycles instead of cars and clean poisonous gases before they come out of factories. Besides, we should plant more trees. If we try our best to take better care of the earth, we will make our world a better place.

【題目】B

When her five daughters were young, Helene An always told them that there was strength in unity (團(tuán)結(jié)). To show this, she held up one chopstick, representing oneperson. Then she easily broke it into two pieces. Next, she tied several chopsticks together, representing a family. She showed the girls it was hard to break the tied chopsticks. This lesson about family unity stayed with the daughters as they grew up.

Helene An and her family own a large restaurant business in California. However, when Helene and her husband Danny left their home in Vietnam in 1975, they didn't have much money.

Soon afterwards, Helene and Diana changed the sandwich shop into a small Vietnamese restaurant. The five daughters helped in the restaurant when they were young. However, Helene did not want her daughters to always work in the family business because she thought it was too hard.

Eventually the girls all graduated from college and went away to work for themselves, but one by one, the daughters returned to work in the family business. They opened new restaurants in San Francisco and Los Angeles. Even though family members sometimes disagreed with each other, they worked together to make the business successful. Daughter Elisabeth explains, "Our mother taught us that to succeed we must have unity, and to have unity we must have peace. Without the strength of the family, there is no business."

Their expanding business became a large corporation in 1996, with three generations of Ans working together. Now the Ans' corporation makes more than $20 million each year. Although they began with a small restaurant, they had big dreams, and they worked together. Now they are a big success.
