Today, roller skating is easy and fun. But a long time ago, it wasn't easy at all. Before 1750, the idea of skating didn't exist. That changed because of a man named Joseph Merlin. Merlin's work was making musical instruments. In his spare time he liked to play the violin. Joseph Merlin was a man of ideas and dreams. People called him a dreamer.
One day Merlin received an invitation to attend a fancy dress ball(化装舞会). He was very pleased and a little excited. As the day of the party came near, Merlin began to think how to make a special entrance at the party. He had an idea. He thought he would get a lot of attention if he could skate into the room.
Merlin tried different ways to make himself roll. Finally, he decided to put two wheels under each shoe. These were the first roller skates. Merlin was very proud of his invention and dreamed of arriving at the party on wheels while playing the violin.
On the night of the party Merlin rolled into the room playing his violin. Everyone was surprised to see him. There was just one problem. Merlin had no way to stop his roller skates. He rolled on and on. Suddenly, he ran into a huge mirror that was hanging on the wall. Down fell the mirror, breaking to pieces. Nobody forgot Merlin's grand entrance for a long time!

As prices and building costs keep rising, the do-it-yourself'(DIY) trend（趋势） in the U.S. continues to grow.
“We needed furniture（家具）for our living room,” says John Ross, “and we just didn't have enough money to buy it. So we decided to try making a few tables and chairs.” John got married six months ago, and like many young people these days, they are struggling to make a home at a time when the cost of living is very high. The Rosses took a 2-week course for $280 at a night school. Now they build all their furniture and make repairs around the house.
Jim Hatfield has three boys and his wife died. He has a full-time job at home as well as in a shoe making factory. Last month, he received a car repair bill for $420. “I was deeply upset (焦虑)about it. Now I've finished a car repair course（课程）, I should be able to fix the car by myself.”
John and Jim are not unusual people. Most families in the country are doing everything they can to save money so they can fight the high cost of living.

A study of older men in The Netherlands, known for its delicious chocolate, showed those who ate the same amount of one-third of a chocolate bar every day had lower blood pressure and a reduced risk of death.
The researchers say, however, it’s too early to conclude that it was the chocolate that led to better health. The men who ate more cocoa products could have eaten other food that made them healthier. Experts also point out that eating too much chocolate can make you fat — a risk for both heart disease and high blood pressure.
“It’s why too early to make recommendations about whether people should eat more cocoa or chocolate,” said Brian Buijsse, an expert for nutrition at Wageningen University in The Netherlands, who co-authored the study.
Still, the Dutch Study, supported by grants (拨款) from the Netherlands Prevention Foundation, appears to be the largest so far to document a health effect for cocoa beans. And it confirms findings of smaller, shorter-term studies that also linked chocolate with lower blood pressure.
Researchers examined the eating habits of 470 healthy men who were not taking blood pressure medicine. The men who ate the most products made from cocoa beans — including cocoa drinks, chocolate bars and chocolate pudding — had lower blood pressure and a 50 percent lower risk of death.
“This is a very important article providing epidemiological support for what many researchers have been observing is experimental models,” said Cesar Fraga of the University of California Davis, who does similar research but was not involved in the new study.
Could the study results apply to women?
“Our study consisted of elderly inch,” Buijsse said. “If you look at the other studies, you will see the same effects in men and women, younger people and older people. The findings may be generalizable to women, but you never know.”
1.We can infer from the last paragraph that ________.
A. It has been concluded that the findings are generalizable to women.
B. It needs confirming whether women can share the same effects.
C. The study results cannot apply to women.
D. The findings are applicable to both men and women.
2.Which of the following has the similar meaning to the underlined word “generalizable?”
A. useful B. popular
C. attractive D. important
3.What is the main purpose of the text?
A. To encourage us to eat as much chocolate as possible.
B. To prove to us that eating chocolate can reduce blood pressure.
C. To inform us of a study about the health benefits of chocolate.
D. To warn us not to eat cocoa products because they can make you fat.

The National Park Service in the United States will mark its one hundredth anniversary in 2016. As it nears its second century, the Park Service plans to increase its educational programs for students and teachers.
The plans include transportation support for one hundred thousand students each year to visit national parks to learn about nature and history. Yellowstone is believed to have been the world’s first national park when it was established in 1872. Other students will get a chance to see parks in faraway places through Skype and other online programs.
The National Park Service also works with partners to provide education. One of its partners is a nonprofit organization called NatureBridge. NatureBridge is celebrating its fortieth anniversary and says one million young people have taken part in its programs. The organization works with students from kindergarten through twelfth grade and uses national parks as its classrooms. It provides field science programs at Yosemite National Park and four other locations in California and the northwestern state of Washington.
Now, NatureBridge is launching an East Coast center with a fourmilliondollar grant from Google. The program will begin in April at the Prince William Forest Park in Virginia. Students stay for three to five days in NatureBridge programs. The activities are aimed at developing their science skills. For example, they learn about different soils and study water quality under a microscope.
Jason Morris is executive vice president of NatureBridge. He says when they are not sleeping, eating or in a laboratory, the students spend their time outdoors. Julia Washburn is associate director of education and interpretation for the National Park Service. She says in a time of budget cuts, the agency has to find ways to still meet its goals. Ms. Washburn says one of the most important services that the Park Service provides every day is nature interpretation. Park rangers (公园管理员) try to make visiting the outdoors more meaningful. Interpretation is a form of informal education. Essentially, it is a word that we use for the people in parks that explain the park or help orient (确定方向) you. So park rangers are interpreters. They orient you to the place you are in and help you make connections, emotional and intellectual connections, with the place.
1.What’s the general idea of the passage?
A. National parks are used as outdoor classrooms for students.
B. Students are called on to be members of NatureBridge.
C. Some famous national parks in US are attractive to students.
D. Park rangers make visiting parks much more interesting.
2.Which of the following is the correct structure of the whole passage? (Para.＝Paragraph)
A.
B. 
C.
D.
