We hold the answers to about all of life's questions in our hands today. But that means our brains are feeling free to take some rest. According to the Daily Mail, our growing reliance on（依赖） the Internet for fact checking is making our memories worse.
Scientists at Harvard University found people now regard Google and other search engines as an outside part of their own brains, rather than a tool. Writing in the Journal Scientific American, Harvard psychologists Daniel Wegner and Adrian Ward warn that people who believe their memorable facts that are saved online are much worse at remembering them.
"The Internet is also unlike a human memory partner; it knows more and can produce the information more quickly, You can find almost all information today easily through a quick Internet search. It may be that the Internet is taking the place of people's memory."
In a series of tests, researchers found it was easy for people to remember information well if they believed it would be deleted.
Those who thought it was stored on a computer were more forgetful, even if they were asked to keep the information in mind.

VI ．任务型阅读。（每空 2 分，共8 分）
The movie Big Hero 6 has delighted audiences of all ages and the biggest reason for its success is the film's superhero, Baymax.
Baymax was made by Hiro's older brother, Tadashi. He wanted to help a lot of people in need and Baymax was how he would do it. At first Baymax was used as a personal healthcare assistant robot to heal the sick and injured. If you are his "patient", he will tell you, "There, there, it will be all right" and he won't leave you alone until you're well again.
After Tadashi died, Hiro upgraded Baymax and changed it into a rocket-fueled fighting machine who can fly above the city of San Fransokyo and take out any enemy. The robot carries Tadashi's selfless personality and through him, Hiro can still keep a little piece of his brother always.
There are some cool things about Bymax. As a robot, Bymax feels no pain, and he carries some special abilities. Bymax can fix himself if necessary. All he needs is some Scotch Tape. The funniest thing about Baymax may be his little footsteps. With a fat body and tiny legs, the superhero has to say "I am not fast," But that doesn't stop him from heading out into the world.
71. Is Big Her0 6 a successful movie?
72. Who was Bymax made by?

One possible vision Dear editor, Last week our class had a discussion about playing “Growing” and “Stealing”games. Some students think that they can grow vegetables, plant trees and flowers on the farm .They enjoy the life in the countryside. At the same time they can earn some e-money and buy more “seeds”, “pets” and even “houses”. They can have the exciting experience of success. Sometimes, some students put some “bugs” in the friends’ gardens. They think they become closer because of the game. They have fun together and reduce their stress. Some students don’t understand this game .They think they are mad about the game, and they are not confident enough to face the real world. It is a waste of time for the students. They don’t have enough time to study. Being a “thief” also makes them feel sad. I think playing the game can make us feel relaxed, but we must spend most of our time studying. Study must come first. Yours, Li Ming
