What do you usually do to get pocket money from your parents? In western countries, many children do chores to get pocket money. They usually start to do this at 10 years old.
School students have to do homework and study for tests. They don’t have a lot of free time in the week. They often do chores at the weekend.
Young kids only do easy chores. So they don’t get much money. But that’s all right. Many of them only want to buy candy. And candy is cheap! They help wash up after dinner and feed the family cat or dog.
When they get older, kids want to buy more and more things. They want things that are more expensive than candy. Then they have to work harder! They often wash the family car, cut the grass, walk the dog and cook dinner.
Some jobs are a good way for kids to learn new things. For example, they can learn to use a lawnmower(割草机) or how to cook. Of course, their parents help them at first.

In some science fiction movies, evil robots refuse to die, no matter how hard people fight back.
Now science fiction has become science fact. For the first time, scientists have made a robot that can take a beating(挨打) and keep on going. Scientists from Cornell University made the robot, which looks like a spider with four legs.
Until now, even the most advanced(先进的) robot was almost certain to break down when it was damaged(毁坏). That is because its computer inside simply doesn’t know how to make the machine work after its shape has changed.
To deal with this problem, the scientists put eight motors(发动机) and two sensors(传感器) that read how the machine is working. They all give signals to the machine’s software. Using this information, the computer can then figure out the machine’s shape at any moment.
The new technology is a big advance in robot-making, scientists say, and it’s far from scary. It may someday help scientists create better artificial(假的) arms and legs and give new freedom to people who lose them. It might also help scientists understand how people and animals figure out their own sense of place in space.
“It has been difficult to design robots that can work well when the environment changes or when it’s damaged,” says Olaf Sporns of Indiana University in US. “With this work, we are nearer to solving this problem.”
【小题1】Why do robots easily break down when they are damaged?

Kelly Christopher, a student at Lutheran High School in California, US, loves oranges. One day last week, she used a pole(竿子) to pick oranges off trees and collect them in baskets. It's the first time in her 15 years she's picked fruit from trees.

 "This is quite different from buying oranges in the supermarket," said Christopher. "Every time I eat an orange, I'll remember this experience."

Christopher was one of the 30 student volunteers at Soil Born Farms. She volunteered as part of a project which was set up in 2009 to help homeowners in South Land Park pick oranges and other fruits out of their backyards. Before, the fruit would rot on the ground or get eaten by animals. Now the fruit is donated to those who need it.

"It is good for many people", said Randy Stannard, who works for the project. "The homeowner gets fruit picked and more people can have healthy food."

"Two harvests (收成 ) were organized in 2009 and volunteers picked 3,000 pounds (1,360kg) of fruit", Stannard said. In 2010, the number was 20,000. This year, Soil Born Farms hopes to get 40,000 pounds. They will harvest every weekend from January to April.

Shannon Galloway, Christopher's science teacher, brought her students into the project this year.

"You're making use of a resource that might be wasted," she said. "I think it's meaningful to everyone."

Donato Frazier, 15, always climbs up a ladder(梯子) and gets on the top of the tree.

"Standing on the treetop is pretty cool," Frazier said. "I can see clearly that many baskets are filled up, and even see that many people are eating healthy fruit because of our volunteer work."
