Always forgetting your long passwords(密碼)? Worried about being hacked(被攻擊)?All these worries will soon become history. Scientists have found that upper-casing(大寫(xiě))your password can help you reduce the chance being hacked.
Usually passwords are six letters or more.However,50 percent of people choose a common word or simple key combination for their password. The most used passwords are 123456, abcdef and abc123. In fact, if your passwords are in lower-case(小寫(xiě)),it will be easily hacked by a hacker. According to a study, it only takes a hacker ten minutes to hack a six-letter password which is in lower-case, but if you make the letter in upper-case, it can take up to ten hours. So if you want to make your account much safer, you should make your password upper-case. Of course, you can also add numbers or symbols to your password. Most of the time a hacker’s computer has to work for 18 days to break a password, but if you choose a nine-letter password that includes numbers and symbols, it can take a hacher’s  computer 44,530 years to break it.

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."                                          
小題1:Christopher and other students went to pick fruits from real trees because they wanted to _____.
A．have some fresh fruit for themselves
B．make some money by selling fruit
C．provide people with more healthy fruit
D．buy some cheap fruit from their neighbors
小題2:When was the project set up?
A．In 2008. B．In 2009.C．In 2010. D．In 2011.
小題3:What will happen to the fruit if they don’t help the homeowners pick it?
A．The fruit will rot or be eaten by small animals.
B．People who need the fruit will come to pick it.
C．The fruit will be used as a resource for research.
D．Homeowners will pick the fruit and sell it.
小題4:What does the underlined word resource mean?
A．資源B．調(diào)查C．對(duì)策D．娛樂(lè)
小題5:How do the students feel about their work?
A．It’s interesting and easy.
B．It’s meaningless and hard.
C．It’s meaningful and exciting.
D．It’s tiring and boring.
