During the summer holiday, some students might have been busy with traveling, summer camps and all kinds of courses. But a special group of Chinese middle school students decided to taste the hardship of life outside school.
Twelve students in a big city sold vegetables at a local market together. Within 12 days, they made more than 1,500 yuan.
Among them, the oldest is 21 years old, while the youngest is just 10. They are all cousins in a big family and eight of them are from rural areas.
“Compared to traveling, such social practice connects us and makes us learn how tough our parents are,” said Dalin, 18, to the City Morning Post. Dalin, a senior high graduate, and her 12-year-old brother Xiaolin came up with the idea.
They learned to work hard to sell their vegetables. Every morning they had to wake up at 3 o’clock. Some of them went to the farmer’s market to buy vegetables. Some of them went to the local market to take up a temporary stall(临时摊位). To lower the cost, they learned to bargain(讲价) with the sellers.
At about 6:30 am, they began to sell vegetables. They peddled(吆喝) loudly to attract customers. After several days, they got some experience, too.
For example, it was better to put vegetables in order and bigger ones on top. When the vegetables are too heavy, they should give customers an extra plastic bag.
When they finally packed up and went home, they had a small meeting. Everyone took notes and shared their feelings.
“We are tired,” said Dalin. “but we gained a lot.”
1.In the writer’s opinion, the 12 students’ action was ________.
A.popular B.encouraging C.strange D.terrible
2.The cousins decided to sell vegetables at a market to ________.
A.show how able they were B.have less hardship of life
C.learn how hard their parents work D.prepare for their future traveling
3.It’s clear that ________.
A.they took up the temporary stall in turn
B.they all gave each customer an extra plastic bag
C.Dalin and Xiaolin got the idea of selling vegetables
D.the elder sold vegetables when the younger took notes

One day, on a small farm in Maine, a man sat in a barn watching a large spider(蜘蛛) on a web. The man was E.B. White -- or Andy, as he was called -- who thought spiders were wonderful creatures. He thought one day he might like to write a children’s book about a spider.
But writing was hard work for Andy. He had written articles and essays and poems.He had also written one children’s book, Stuart Little. But Andy could never just rush to turn an idea into an article or a book. He told his editor (编辑) that he needed to let his ideas ripen.
So for years, Andy continued to think about writing a children’s book about a spider. He did some of his best thinking while he walked slowly around his farm.
Once while he was cleaning his barn, he found a spider’s egg sac (卵囊). Andy wanted to see the eggs hatch(孵蛋). But he was going to leave for New York City. So he found a small box and carefully placed the egg sac inside. When he got to his hotel, he put the box on the dresser. The next morning , there were hundreds of baby spiders rushing across the dresser!
Years later, Andy finally began writing Charlotte’s Web, the story of a spider named Charlotte and a pig named Wilbur.

You may charge(充电) your phone every day, but do you clean your phone as much? Whatever your hands touch, your phones touch. It has been discovered that some phones have 18 times more bacteria and viruses (细菌病毒) than any surface in a public restroom. So it won’t surprise you that a 2011 University of London study found that one in six of our phones have bacteria and viruses on them.
The research on bacteria and viruses led to the invention of PhoneSoap. It is not actually liquid (液体). It is a phone charger that uses the electromagnetic radiation (辐射) to kill 99.9 percent of bacteria and viruses, cleaning your phone while it charges.
“Certain types of bacteria and viruses are really on our phones,” says Wes Barnes, the PhoneSoap founder. “It would be the fastest, most powerful way to kill them .”
PhoneSoap looks like a little metal suitcase. Your phone rests in to charge and get cleaned at the same time. Instead of plugging your phone into the wall, you’d plug it into the PhoneSoap charger box. The process only takes a few minutes but, Barnes says, “The idea is that you can leave it in there overnight if you want to keep charging. and it cleans the phone fully.”
The founder found the right companies and then started shipping the product in late November. By last week’s International Consumer Electronics Show in Las Vegas, PhoneSoap was very popular with people. The founder has left his present job and is selling PhoneSoap without a stop. “We sell out PhoneSoap every day, and we will try to provide enough PhoneSoap” Barnes says. “It’s been a great challenge.”
