You can relax if remembering everything isn't your strong suit. Recent research makes the case that being forgetful can be a strength—in fact, selective memory can even be a sign of stronger intelligence.
Traditional research on memory has focused on the advantages of remembering everything. But looking through years of recent memory data, researchers found that the neurobiology of forgetting can be just as important to our decision-making as what our minds choose to remember.
Making intelligent decisions doesn't mean you need to have all the information at hand. It just means you need to hold onto the most valuable information. And that means clearing up space in your memory palace for the most up-to-date information on clients and situations. Our brains do this by creating new neurons(神经元)in our hippocampus, which have the power to overwrite(重写)existing memories that are influencing our decision-making.
If you want to increase the number of new neurons in our brain ’ s learning region,try exercising. Some aerobic exercise like jogging, power walking and swimming has been found to increase the number of neurons making important connections in our brains.
When we forget the names of certain clients or details about old jobs,the brain is making a choice that these details don't matter. Although too much forgetfulness can be a cause for concern,the occasional lost detail can be a sign of a perfectly healthy memory system. The researchers found that our brains facilitate decision-making by stopping us from focusing too much on unimportant past details. Instead,the brain helps us remember the most important part of a conversation.
We can get blamed for being absent-minded when we forget past events in perfect detail. These findings show us that total recall(记忆)can be overvalued. Our brains are working smarter when they aim to remember the right stories, not every story.
1.How can we help our brains produce more neurons? '
A. By having deep sleep frequently.
B. By practicing swimming regularly.
C. By doing mental labor repeatedly.
D. By learning new skills constantly.
2.Which of the following can best replace “facilitate” underlined in paragraph 5?
A. postpone B. repeat
C. promote D. abuse
3.What conclusion can be drawn from the text?
A. Memory loss is well worth noticing.
B. Decisions can’t be made without memories.
C. We shouldn't stress total recall too much.
D. Forgetting is even more important than remembering.

请阅读下面短文,并根据所读内容在文章后表格中的空格里填入一个最恰当的单词。
注意:每个空格只填一个单词。
You can relax if remembering everything is not your strong suit. Recent research makes the case that being forgetful can be a strength—in fact, selective memory can even be a sign of stronger intelligence.
Traditional research on memory has focused on the advantages of remembering everything. But looking through years of recent memory data, researchers Paul Frankland and Blake Richards of the University of Toronto found that the neurobiology(神经生物学) of forgetting can be just as important to our decisionmaking as what our minds choose to remember.
“The goal of memory is not the transmission of information through time. Rather, the goal of memory is to help improve decisionmaking. As such, transience(转瞬即逝) is as important as persistence in memory systems,” their study in Neuron states.
Making intelligent decisions does not mean you need to have all the information at hand, it just means you need to hold onto the most valuable information. And that means clearing up space in your memory palace for the most uptodate information on situations. Our brains do this by generating new neurons(神经元) in our hippocampus(海马体), which have the power to overwrite existing memories that are influencing our decisionmaking.
“If you're trying to deal with the situation and your brain is constantly bringing up multiple conflicting memories, that makes it harder for you to make a wise decision,” Richards told Science Daily.
If you want to increase the number of new neurons in your brain's learning region, try exercising. Moderate aerobic exercise like jogging, power walking, and swimming have been found to increase the number of neurons making important connections in our brains.
When we forget the names of certain clients and details about old jobs, our brain is making a choice that these details do not matter. Although too much forgetfulness can be a cause for concern, the occasional lost detail can be a sign of a perfectly healthy memory system. The researchers found that our brains facilitate decisionmaking by stopping us from focusing too much on minor past details. Instead, the brain promotes generalization, helping us remember the most important gist of a conversation.
“One of the things that distinguishes an environment where you're going to want to remember stuff versus an environment where you want to forget stuff is this question of how consistent the environment is and how likely things are to come back into your life,” Richards said.
If you're an analyst who meets with a client weekly, your brain will recognize that this is a client whose name and story you need to remember. If this is someone you may never meet again, your brain will weigh that information accordingly.
These findings show us that total recall can be overrated. Our brains are working smarter when they aim to remember the right stories, not every story.

Can you believe everything that you read? It seems as if every day, some new articles come out about a new discovery about this or that. For example, water is bad for you, or good for you. The answer depends on which scientific study has just come out. People cannot decide which food items are healthy, how pyramids were constructed, and why dinosaurs disappeared. When we look for answers we sometimes can believe persuasive researches and scientists. But how trustworthy are they really? Here are two examples of scientific hoaxes (骗局).
As far back as 1726, Johann Beringer was fooled by his fellow scientists into thinking he had made an amazing discovery. The fossils of spiders, lizards, and even birds with the name of God written on them in Hebrew were unlike anything that had been found before. He wrote several papers on them and was famous for those only to have it revealed that they were planted by jealous colleagues to ruin his reputation.
When an early human being was discovered in 1912, scientists at this time were wild with excitement over the meaning it had for the theory of evolution. There were hundreds of papers about this Piltdown man over the next fifty years until it was finally discovered to be a complex hoax. The skull (头骨) of a man had been mixed with the jawbone of an orangutan (猩猩) to make the ape (猿) man.
The next time you read the exciting new findings of a study of the best scientist, do not automatically assume that it is true. Even qualified people can get it wrong. Though we certainly should not ignore scientific research, we do need to take it with a grain of salt. Just because it is accepted as the truth today does not mean it will still be trustworthy tomorrow.
1.What is the reason why Johann Beringer was fooled?
A.His fellow scientists wanted to make fun of him.
B.His workmates are eager to become famous too.
C.These scientists made a mistake because of carelessness.
D.His colleagues was jealous of him and did so to destroy his fame.
2.The excited scientists thought that this Piltdown man ________.
A.was in fact a complex hoax
B.was a great scientific invention
C.contributed to the theory of evolution
D.had the skull like that of an ape
3.What does the underlined phrase “with a grain of salt” in Paragraph 4 mean?
A.Happily. B.Generally.
C.Doubtfully. D.Completely.
4.What can we learn from the passage?
A.Hebrew is probably a kind of language.
B.Truths of science will never be out of time.
C.People believe scientists because they are persuasive.
D.We are advised to believe famous scientists.

What will you do if you can’t eat everything bought in the canteen? 1. According to a survey, what students waste every year could feed over 10 million people.
2. According to Xinhua News Agency, the food wasted by Chinese people is about 50 million tons of grain every year, which could feed 200 million people.
Food waste, which has become a global issue, serves as a mirror that reflects various cultural and social issues in different countries. In the West, for instance, consumerism, the belief that it’s a good thing to use a lot of goods and services, is often to blame for food waste. 3. Chinese people are well known for being hospitable and generous. Many even feel that they lose face if their guests have eaten all the food. On campus, a generation of single children is less aware of the food waste issue. Students nowadays are well protected by their families and hardly have any concept of how much toil others go through in order to provide them with the food they eat.
4. There are over 925 million hungry people in the world, most of whom live in underdeveloped countries and areas. They don’t have enough food to eat. Many children die for lack of nutrition each year in some African countries. And farmers work very hard to grow the crops. 5. It’s also important that everyone should think about how they can do their bit to reduce food waste.
A. Students’ waste is extremely serious.
B. China, in turn, features its own eating culture.
C. But canteen waste is extremely the tip of the iceberg.
D. Students can never realize the serious food crisis.
E. Compared with them, some live in a different world.
F. So there’s no excuse that we should waste our food.
G. Most of us would simply throw away any leftover food.
