1 . Smart phones are greatly changing the way we walk down the street. Office workers and young people are walking like the old as they check emails and messages.
Scientists have found mobile phones make us walk more slowly, with modest steps, to avoid falling over. The leader of the study said the walk is just like someone in their eighties. Researchers found people writing a text message walk more than twice as slowly as those without a phone, finding it harder to stay in a straight line.
The scientists examined 252 people walking while reading a text message, writing one, speaking on their phones or without their phones at all. Writing a text is the hardest activity, causing people to look down at their phone 46 percent more, and 45 percent longer, than when reading a message. This led people to walk 118 per cent more slowly than when they were without their phones. People walked almost a third more slowly while reading a text and 19 per cent while talking on the phone.
Smart phones were found to stop people from walking in a straight line, putting them at greater risk of running into other people, cars or street lamps. This increased the need to slow down and take more careful steps.
John Timmis said the idea for this study came from following someone walking down the street in the afternoon, who was walking as if he had had several drinks. I thought it was a bit early for that, then walked up alongside him and saw that he was on his phone. Simply being on the phone changes the way people walk.

2 . As Shanghai prepared to introduce mandatory(强制的) garbage sorting on July 1, games and toys that examined fun ways to spread information about the garbage sorting were to encourage younger people to take action.
A 15-second video of a game went on Chinese social media. In the video, players wearing VR(虚拟) headsets saw four different types of trash can in front of them, and had to throw different types of garbage into the right buckets(桶) to get points. Although it was not the only VR game in the place, visitors lined up around the booth to explore it because of the garbage-sorting theme.
“As a Shanghai, I am in great need of this game. Maybe I won’t need to check how to categorize(分类) each piece of garbage on my phone while going through all my garbage every day if I play this game more often, ” said ZhouZhou, a young Shanghai. But some social media users in Shanghai have complained about the difficulty of sorting different types of garbage.
Wu Xia, founder and CEO of VitrellaCore, the company that created the game, said the idea was to provide an interesting way of learning about garbage sorting. “It’s simple and easy to understand. People can practice sorting garbage without actually going through their trash, and it is a more effective method than using paper materials when training volunteers,” Wu said.

3 . How many phone numbers can you remember by heart? It’s probably fewer than you would like. Actually, you’re not alone. Some said that they couldn’t recall the phone numbers of their friends and neighbors. And others said that they couldn’t remember their relatives, phone numbers. In their eyes, there is no point in filling their heads with phone numbers if they’re all stored in smart phones that are with them almost all the time.
In fact, most people are suffering from a sort of digital amnesia(健忘). More than 90%℉ those agreed that they used the Internet as an online extension of their brains. Rote memorization(死记硬背) was once an important part of education, but we just need a click the computer or slide now. That’s making us worse at remembering things.
However, I believe that there are more risks to this new world of memory beyond losing our ability to recall some information such as who the 15th President was. That kind of information may always be a click away, but the important things are personal ones, like the way your parents smile at your wedding. It’s harder to recall or find online. If you’re relying on yourself to keep track of those memories, they will be much more meaningful.
1. Paragraph 1 is mainly used to ________.| A．serve as the background of memory | B．introduce the topic |
