People in the United States honor their parents with two special days： Mother's Day, on the second Sunday in May, and Father's Day, on the third Sunday in June.
Mother's Day was proclaimed a day for national observance by President Woodrow Wilson in 1915. Ann Jarvis from Grafton, West Virginia, had started the idea to have a day to honor mothers. She was the one who chose the second Sunday in May and also began the custom of wearing a carnation.
In 1909，Mrs. Dodd from Spokane, Washington, thought of the idea of a day to honor fathers. She wanted to honor her own father, William Smart. After her mother died, he had the responsibility of raising a family of five sons and a daughter. In 1910，the first Father's Day was observed in Spokane. Senator Margaret Chase Smith helped to established Father's Day as a national commemorative day, in 1972.
These days are set aside to show love and respect for parents. They raise their children and educate them to be responsible citizens. They give love and care.
These two special days are celebrated in many different ways. On Mother's Day people wear carnations. A red one symbolizes a living mother. A white one shows that the mother is dead. Many people attend religious services to honor parents. It is also a day when people whose parents are dead visit the cemetery. On these days families get together at home, as well as in restaurants. They often have outdoor barbecues for Father's Day. These are days of fun and good feelings and memories.

"It hurts my back when I run，" said Beeline Reyes, a student in Virginia. "It's hard to get up the stairs with my backpack because it's too heavy. "
Students have to carry heavy backpacks on their backs for a whole week's study. Beeline is one of them. They have regular back-packs with two straps （带子）to carry them, but a number of students with heavy loads have switched to rolling backpacks. The backpacks have wheels and can roll on the ground.
Shirley Park's backpack weighs 10 kilos, and she said，"I'll change to a rolling backpack because I am starting to have back pain. "
How much is too much? Experts say that students should carry no more than 10 to 15 percent of their own body weight. A few students have had a good idea to lighten the load ： Less homework.

In the second half of each year, many powerful storms are born in the tropical （热带的）Atlantic and Caribbean seas. Of these, only about half a dozen becomes the strong, circling winds of 75 miles per hour or more that are called hurricanes, and several usually make their way to the coast. There they cause millions of dollars of damage, and bring death to large numbers of people.
The great storms that hit the coast start as soft circling wind hundreds-even thousands-of miles out to sea. As they travel aimlessly over water warmed by the summer sun, they are carried west-ward by the southeast winds. When conditions are just right, warm, moist（潮湿）air flows in at the bottom of such a wind, moves up-ward through it and comes out at the top. In the process（过程），the moisture in this warm air produces rain, and with it the heat is changed to energy in the form of strong winds. As the heat increases, the young hurricane begins to move in a counter-clockwise motion（逆时针运动）.
The life of a hurricane is only about nine days, but it contains almost more power than we can imagine. The energy in the heat re-leased （释放）by a hurricane's rainfall in a single day would satisfy the entire electrical needs of the United States for more than six months. Water, not wind, is the main source of death and destruction（毁灭）in a hurricane. A typical hurricane brings 6 to 12 inch downpours, causing sudden floods. Worst of all is the powerful movement of the sea-the mountains of water moving toward the hurricane center. The water level rises as much as 15 feet above normal as it moves toward shore.
When is an ordinary tropical storm called a hurricane?

A．When it begins in the Atlantic and Caribbean seas.

B．When it hits the coastline.

C．When it is more than 75 miles wide.

D．When its winds reach 75 miles per hour.

What is the worst thing about hurricanes?

C．That they last about nine days.

Here the word "downpour" means __________.

A．heavy rainfall

C．the progress of water to the hurricane center

D．the increasing heat

A．It travels more than 75 miles per hour.

B．It usually stays about 9 days.

C．It usually causes 6 to 12 inch downpours.

The Pacific island nation of Nauru used to be a beautiful place. Now it is an ecological disaster area. Nauru's heartbreaking story could have one good consequence-other countries might learn from its mistakes.
For thousands of years, Polynesian people lived on the remote island of Nauru, far from western civilization. The first European to arrive was John Fearn in 1798. He was the British captain of the Hunter, a whaling ship. He called the island Pleasant Island.
However, because it was very remote, Nauru had little communication with Europeans at first. Then whaling ships and other traders began to visit, bringing guns and alcohol. These elements destroyed the social balance of the twelve family groups on the island. A ten-year civil war started, which reduced the population from 1，400 to 900.
Nauru's real troubles began in 1899 when a British mining company discovered phosphate（磷酸盐）on the island. In fact, it found that the island of Nauru was nearly all phosphate, which is a very important fertilizer for farming. The company began mining the phosphate.
A phosphate mine is not a hole in the ground; it is a strip mine. When a company strip-mines, it removes the top layer of soil. Then it takes away the material it wants. Strip-mining totally destroys the land. Gradually, the lovely island of Nauru started to look like the moon.
In 1968，Nauru became one of the richest countries in the world. Every year the government received millions and millions of dollars for its phosphate.
Unfortunately, the leaders invested the money unwisely and lost millions of dollars. In addition, they used millions more dollars for personal expenses. Soon people realized that they had a terrible problem-their phosphate was running out. Ninety percent of their island was destroyed and they had nothing. By 2000，Nauru was al-most financially ruined. Experts say that it would take approximately$433，600，000 and more than 20 years to repair the island. This will probably never happen.
What might be the author's purpose in writing the text?

A．To seek help for Nauru's problems.

B．To give a warning to other countries.

C．To show the importance of money.

D．To tell a heartbreaking story of a war.

What was Nauru like before the Europeans came?

A．Rich and powerful.

B．Modern and open.

C．Peaceful and attractive.

D．Greedy and aggressive.
