Did you ever bring your phone to school? It doesn't seem bad to take a quick look at a phone message or an email in class. But a new study has found this can make students get lower grades in exams.

In the study, researchers (研究者) studied 118 students. These students took the same couse. They also had the same teacher and used the same textbooks. They couldn't use their digital devices (數(shù)碼設(shè)備)in half of their class. But they could use them in the ?ther half. Researchers found that using digital devices made students get lower scores in the final exam. Students díd worse in what they learned on device days. What's more, when some students used digital devices in class, even those not using their phones or computers got worse grades. Researchers say there are maínly two reasons for the resuls.First,students hardly ask questions when they are using their phones or computers. They talk less with their classmates and teachers. Second, even if a student doesn't want to look at the screen, he just can't help it.So remember to turn off your phone in class. This is good not only for you, but also for the whole class.

1.In the study, 118 students took the same course, had the same teacher and used the same textbooks.

2.In the study, students can't use any digital devices in the whole class.

3.Those not using their phones or computers got better grades on device days.

China was once known as the “Bicycle Kingdom”. Now, a young US man, David Wang, living in Beijing is using pieces of bamboo to replace(代替) parts of bicycles.

Two years ago, David opened the Bamboo Bicycle Beijing workshop in Langjia hutong. They cut and shape bamboo into bicycle frames(構(gòu)架). After connecting the pieces with special glue, they join wheels and other parts together.

After graduating from university, David came to China to continue his study. He has lived in China for more than 6 years and loves the city's ancient hutongs. However, he found people threw old bicycles everywhere in hutongs. “Beijing is becoming a big graveyard(墓地) of bicycles，” David said. He began picking up the given?up bikes and “saving” them, repairing, repainting, and renewing them.

Then one day he found a really old bicycle, which could not be “saved” in usual ways, so he began thinking of better materials to replace the frame. Bamboo came to his mind.

He searched online, and after three months of research and tries, communicating with factories and experts, he made his first bamboo bicycle. “It was amazing! It really works！” he recalled.

The bikes are not for sale—they're to encourage a love of cycling among people who live in Beijing. David hopes bamboo bicycles can create “a little bit more different culture in Beijing”．

Although it’s not easy for us to forgive people who hurt us, it is possible. “Forgiveness makes you more hopeful. And it’s good for our health,” says Frederic, PhD, the writer of the book called Forgive for God.

But how can we forgive others? It’s really a problem. Let’s see how we can do it? First, think of something beautiful and the people you love. Try to get yourself happy. Second, don’t wait for others to say sorry to you. If the people hurt you, he or she won’t say sorry to you. They may not just want to hurt you or they just don’t see things the same way. Third, try to see things in others’ shoes. You can write a letter to yourself from the offender’s point.(肇事者的觀點) That can make you understand others better and make yourself happier. Don’t forget to forgive yourself. For some people, forgiving themselves is the biggest challenge. And it also makes you more confident.

A young man once went into a town and bought himself a pair of trousers. When he got home, he went upstairs to his bedroom and put them on. He found that they were about two inches too long.

He came downstairs, where his mother and his two sisters were washing up tea things in the kitchen. “These new trousers are too long.” He said. “They need shortening (縮短)by about two inches. Would one of you mind doing this for me, please? ” His mother and sisters were busy and none of them said anything.

But as soon as his mother had finished washing up, she went quietly upstairs to her son’s bedroom and shortened the trousers by two inches. She came downstairs without saying anything to her daughters.

Later on, after supper, the elder sister remembered her brother’s trousers. She was a kind-hearted girl, so she went quietly upstairs without saying anything to anyone, and shortened the trousers by two inches.

The younger sister went to the cinema, but when she came back, she, too, remembered what her brother had said. So she ran upstairs and took two inches off the legs of the new trousers.
