If you saw another kid ride her bike too fast around a corner and fall down, you might ride your bike more slowly on that turn. Yes, we humans are very sensitive to others' mistakes. And the same is true for other animals. Animals mess up all the time. They might eat poisonous leaves, fall off a tree or let their prey (猎物) slip away. By watching others fail, an animal can avoid making the same mistakes, thus improving its chance of survival.
Scientists suspected that one part of the brain helps animals process information about others' errors. Cells in that part appear to become more active when a person sees someone else making a mistake. But researchers didn't know whether individual cells in this part of the brain play different roles in detecting errors.
To investigate the brain's response to errors in more detail, the researchers taught a game to two macaques, a type of monkey. One monkey could press a yellow or green button while the other watched. If the first monkey pressed the right button, the team gave both animals a treat. Every couple of rounds, the two monkeys switched roles. Meanwhile, the scientists monitored individual cells in the animal's brains.
When the first monkey messed up the game by pressing the wrong button, a group of cells in the second monkey's brain fired. But if the second monkey also made the wrong choice during its turn, some of the cells in that group didn't respond. Those unresponsive cells reacted specifically to mistakes made by others, not to the monkey's own mistakes.
Scientists believe other parts of the brain also might help people process information about another's errors. "You start to think about this other person and see things from his angle. " Ellen de Bruijn, told Science News. She studies the brain at the University of Leiden in the Netherlands. According to Paragraph 1 , animals' ability to learn from others' mistakes ______.
| A．used to be ignored by humans |
| B．ensures that they will never fail |
| C．is being lost because of humans |
| D．helps them to survive better |
The underlined word "detecting" in Paragraph 2 probably means "______".
| A．correcting | B．making | C．sensing | D．drawing |
In the experiment mentioned, those unresponsive cells are only sensitive to ______.
| A．the same buttons | B．others' mistakes |
| C．one's own mistakes | D．the monkey's brain |
Last Thursday, Michael and Linda stood behind large food trucks distributing meals to 4,000 homeless people for their wedding reception on the border town of Kilis. The couple had decided that instead of hosting their friends and family for a traditional feast reception, they would feed the victims from an earthquake-stricken area.
The idea came from the bridegroom's father, Ted, who volunteers for a Turkish relief organization. For the past few years, the organization has distributed daily meals to thousands of people who've suffered from natural disasters. He approached a representative of the organization and suggested that the family cover part of the costs of feeding them for the day.
Then he told his son, who was surprised by the suggestion, but soon won over. When he told that to the bride, she was really shocked but finally accepted because in southeastern Turkey there is a real culture of sharing with people in need. They love to share their food, their table and everything they have. And afterwards she was quite amazed about it. So, they arrived at the distribution center on Thursday to spend the day serving food and taking photographs with their grateful recipients（接受者）．
On Tuesday evening, the newly married couple were still pleased with their decision to quit a personal celebration for one with a greater good. "It's like sharing a dinner with your friends and family who have this kind of thing on a daily basis or sharing something with people who don't even have the most basic things," Michael said. "Hopefully, this will also give the start for other wedding dinners to be held here with our brothers and sisters in need."Why did so many people crowd in Kilis?
| A．To attend Michael and Linda's wedding. |
| B．To support the organization. |
| C．To escape the damaging earthquake. |
| D．To help distribute free daily meals. |
How did the couple celebrate their wedding?

| B．They shared their happiness with the homeless in Kilis. |
| C．They afforded the entire cost of the day for feeding victims. |
| D．They took photos with the grateful victims. |
What does the underlined word "approached" in Paragraph 2 mean?
| A．took in | B．moved towards |
| C．came across | D．consulted with |
We can know from the text that __________________..
| A．Kilis is a place which lies in southeastern Turkey |
| B．Ted was a representative of the organization |
| C．Linda adopted the suggestion immediately she heard it |
| D．Michael doubted if more new couples would follow him |
My students often tell me they don’t have “enough time” to do all their schoolwork. My reply is often brief –You have as much time as the president. I usually carry on a bit about there being 24 hours per day for everyone, and suggest that “not enough time” is not an acceptable explanation of not getting something done.
Once in graduate school, I tried to justify myself to one of my professors by saying that I was working. His answer to me was, “That’s irrelevant. What’s important is the quality of your work.” Since then I have had time to reflect on the “hard worker” dodge(伎俩), and I have come to some conclusions – all relevant to the issue of how much time we have.
If you look at the matter analytically, you can identify two parts of the problem. There is, of course, the matter of “time”, which we can think of as fixed. Then there is the issue of “work” during that time, which can vary in intensity. But, as my professor suggested, it’s not diligence but the quality of the product that is important.
That led me to a new idea, the quality of work. That concept is perhaps best explained by a sign I once saw on the wall in someone’s office – Don’t work harder but work smarter! There’s a lot of sense in that idea.
If you can’t get more time, and few of us can, the only solution is to improve the quality of work. That means thinking of ways of getting more out of the same time than we might otherwise get. That should lead us to an analysis of our work habits. Since “work” for students usually means “homework”, the expression “work habits” should be read as “learning habits”.
Then, as a smart student, you will seek to improve those skills that you use in study, chiefly reading and writing. If you learn to read better and write better, there are big benefits that pay off across the board in all your studies.From the passage, we know that the author is _____.
