Rocky Lyons was five years old when his mother，Kelly，was driving along the country road with him.He was asleep on the front seat of their truck，with his feet resting on her lap.As his mom drove carefully down the winding country road，she turned onto a narrow bridge.The truck hit a rock and slid off the road.She attempted to bring it back up onto the road by pressing hard on the gas pedal(踏板) and turning the steering wheel(方向盘) to the left.But Rocky’s foot got caught between her leg and the steering wheel and she lost control of the truck.

The truck fell into a 20?foot ravine(峡谷)．When it hit bottom，Rocky woke up.“What happened，Mama？” he asked.“Our wheels are pointing toward the sky.”

Kelly was seriously wounded and blinded by blood.“I’ll get you out，Mama，”announced Rocky，who had surprisingly escaped injury.He climbed out from under Kelly，slid through the open window and tried to yank his mother out.But she didn’t move.

“Just let me sleep，” begged Kelly，who was out of consciousness.Rocky insisted，“Mom，you can’t go to sleep.”

Rocky managed to push Kelly out of the truck and told her he’d climb up to the road and stop a car to get help.Fearing that no one would be able to see her little boy in the dark，Kelly refused to let him go alone.Instead they slowly moved up to the road.The pain was so great that Kelly wanted to give up，but Rocky wouldn’t let her.

Rocky kept repeating the inspirational phrase，“I know you can，I know you can.”When they finally reached the road，Rocky broke into tears seeing his mother’s torn face clearly for the first time.Waving his arms and shouting, “Please stop！” the boy stopped a truck.His mother was sent to hospital.

It took 8 hours to rebuild Kelly’s face.She looks quite different today—“I used to have a straight long nose，thin lips and high cheekbones；now I’ve got a flat cheeks and much bigger lips”—but she has few scars and has recovered from her injuries.

Rocky’s heroics were big news.Everyone was surprised at this little boy’s power.“It’s not like I wanted it to happen，” the boy explained.“I just did what anyone would have done.” “If it weren’t for Rocky，I’d have died，” said his mother.

Bicycles are a great way to get around. They’re fun to ride, especially down hills. And, as you speed along the road, you might also think of ways in which you could improve your bike— make it safer, more efficient, or more comfortable. In fact, the two-wheeled machines make for some cool science projects.
This year's Intel International Science and Engineering Fair (ISEF), held last May in Cleveland, featured（had）three bicycle projects from three countries. Like many of the other experiments presented at ISEF, the bike projects showed that some of the most interesting scientific research often begins by taking a closer look at things you care about.
Renato Angulo Chu had even grander ambitions. The 12th-grader from Lima, Peru, wanted to address some of his country's economic troubles.
"I see a problem in my country," Renato said. "If you go to the forests in Peru, in some places you cannot find electricity. If you go with my bicycle, you can turn on the lights."
Renato, 16, spent 3 years designing his special Multibike. The device looks like a fixed exercise bike. It has wires fixed along the frame and a blender strapped (fastened) to the back. Turning the pedals operates the blender. The same principle can be used to sharpen knives or sweep city streets.
The Multibike can work either as a fixed bike or as a bicycle able to travel city streets and country roads. It's made from inexpensive materials, and the user gets exercise while pedaling to operate a machine.
"You pedal the bike, and you can mix any drink you want," Renato said. More importantly, he added, the same concept could be used to bring light to houses in remote regions of the rainforest.
【小题1】What can we learn from the first paragraph?

Canada, the world’s second-largest country, has a massive Atlantic coastline (海岸线). So, the best way to experience it is by car.
★ One week
Cross over to Wolfville and the Bay of Fundy via HWY 12. Spend a day criss-crossing the country roads and grassy hills of Cape Blomidon to catch some of the most impressive views of the Fundy tides (潮水).
The next day, drive east, stopping at wineries (酿酒厂) and shopping for unique jams and other local foods at Tangled Garden, where you can also cool down with a herb-flavored ice cream.
Drive through the rural roads and maybe get lost on the way to Maitland to sign up for a day of white-water rafting, which can be relaxing and one of the most exciting experiences in your life.
On the last day, head back to Halifax via east coast Martinique Beach, one of the longest beaches in Nova Scotia, a beautiful place for stretching legs and bird watching.
★ Two weeks
With more time, you can go directly up to Cape Breton, along the circuitous (迂回的) roads of the “Cabot Trail”, over high sea vista points, where you have to watch for moose (驼鹿) on the road.
Those with more time can go to Newfoundland and continue on the “Viking Trail” that links the Gros Morne National Park with Leif Eriksson’s historic Viking settlement.
★ When to go
Outside of June to October the coast will be extremely cold and most businesses will be shut.
★ Where to stay
● Lennox Inn 1791 (Lunenburg): Canada’s oldest continually operating hotel.
● The Olde Lantern Inn & Vineyard (Grand Pre): in the heart of winery and Fundy tide country.
★ Where to eat
● Fleur de Sel (Lunenburg): widely considered this coast’s finest restaurant.
● Hall’s Lobster Pound (Hall’s Harbour): pick your lobster, get it boiled and enjoy it on a park bench.

In the 19th century, Americans from the eastern states moved out west to settle in the rich new lands along the Pacific Coast. The most difficult part of their trip was crossing “the Great American Desert” in the western part of the United States by horse and wagon.
The western desert can be very dangerous. There is little water and there are few trees. But the desert also has scenery of great beauty. Tall towers of red and yellow stone rise sharply from the flat, sandy valley floor. The scene has been photographed many times and appears in movies and on TV.
In Arizona, man-made dams across the Colorado River have made two large lakes in the middle of the dry desert country. At Lake Powell, the red stone arch of Rainbow Bridge rises high above the blue lake.
There are few roads. Many areas of Lake Powell’s shore can only be reached by boat or on foot. But hikers in this empty desert land sometimes find very old native American pictures, painted on the rocks.
In Death Valley, California, the summer temperature rises to 130°F—165°F. There is less than inches of rain each year. Death Valley is the lowest place in America---925 meters below sea level. In the 1800s, many travelers died when they tried to cross this waterless valley in the terrible heat.
Although the desert is dry and seems empty, there is plenty of life if you look closely. Snakes and rats have learned how to live in the desert heat. They live underground and come out at night, when it is cool. Plants such as cacti need very little water. When it does rain in the desert (sometimes only once or twice a year), plants grow quickly, and flowers open in a single day. For a short time, the desert is covered with brilliant (very bright) colors.
