Is the world too crowded? Well, that’s a hard question to answer. It’s all a matter of perspective(視角).In Montana, you might drive for a mile in any direction and not see another human being. In Macao, 60,000 people live in every square mile!
What is true is that the world’s population doesn’t stay the same. It has been increasing at a very fast rate(比例).That’s in part because in each generation(代) these are more people who then have children than in the last generation.
Five hundred years ago, the population of the world was about 460 million. In 1900,the world’s population was under 2 billion(十億).Right now it is doubling every 40 years. That means, if this rate of growth continues, when you are a parent, there will be twice as many people on earth as there are now. Wow! Now that’s a whole lot of people! Soon the world’s population will probably reach 7 billion. Some people worry about that! But there is a lot of disagreement about just how many people on earth equals(相當(dāng)于) too many people. But everyone agrees that the more people there are, the more resources(資源) the world needs to feed, house and take care of all of them, and the more need there is to think carefully about how we live and use the earth’s resources.

根據(jù)短文內(nèi)容．回答下列問題。
More and more young people from China begin to celebrate ( 慶祝 ) Father’ s Day. They send fathers presents, or invite them for a nice dinner. But do you know how Father’s Day started?
While Mrs Dodd, from America, was listening to a talk about Mother’ s Day in a church in 1909, she had an idea of having Father’s Day to honor(紀(jì)念) her father, William Smart. Mr Smart used to be a soldier. His wife died when she gave birth to her sixth child. Mr Smart had to raise his six children alone. They lived a hard life. After Mrs Dodd grew up, she wanted to thank her father for what he had done for them. She wrote a letter to a church and asked for the third Sunday in June to be Father’ s Day. The church agreed with her.
The first Father’ s Day was celebrated on June 19th, 1910 in Washington. Children made special desserts, and did other things to make their fathers happy. In 1924, President(總統(tǒng)) Calvin Coolidge supported the idea of a national Father’ s Day. People all over the country began to celebrate Father’s Day. Finally, in 1966, President Lyndon Johnson made the third Sunday in June Father’s Day.
This year, Father’s Day was on June 17th. What did you do for your father?
