How to Active Brain Cells
Scientists used to think that your brain stopped growing new cells once you reached adulthood. Happily, current research shows that it isn’t true! As you get older, you can continue to grow new brain cells.
Get regular aerobic (有氧的) exercise.
Research shows that regular aerobic exercise over a long period of time can better stimulate brain cell growth than other forms of exercise. Add aerobic activities, such as swimming, power walking, or jogging, into your regular routine.1.
Do stress-relieving activities.
Activities that reduce stress and give you a sense of wellbeing can encourage the growth of new brain cells.2. You can do some yoga, read your favorite book, or listen to relaxing music.
3.
Antioxidant-rich foods can prevent damage to your current brain cells and promote the growth of new, healthy cells. Omega 3 fatty acids may also help improve your brain health. Add plenty of brain-boosting foods into your diet, such as vegetable oils, nuts, green tea, blueberries and fatty fish.
Maintain an active social life.
4. It’s also good for your brain. Socializing helps keep your brain cells active, preventing some of the loss of brain function. If you can’t socialize in person, reach out to your friends over the phone or on social media.
Get plenty of good-quality life.
If you’re an adult, try to get 7 – 9 hours of sleep each night. If you’re a teen, aim for 8 – 10.
Your brain heals itself from the day’s stresses while you sleep.5.You can improve your sleep by going to bed and waking up at the same time every day.

F.Fortunately, there are treatments that can help you restore your brain’s health.
G.It also processes information you picked up during the day, helping you to learn and preserve new memories.
If you were like most children, you probably got upset when your mother called you by a brother’s or sister’s name. How could she not know you? Did it mean she loved you less?
Probably not. According to the first research to deal with this topic head-on, misnaming the most familiar people in our life is a common cognitive (认知的) error that has to do with how our memories classify and store familiar names.
The study, published online in April in the journal Memory and Cognition, found that the “wrong” name is not random but is always fished out from the same relationship pond: children, friends, brothers and sisters. The study did not examine the possibility of deep psychological significance to the mistake, says psychologist David Rubin, “but it does tell us who’s in and who’s out of the group.”
The study also found that within that group, misnamings occurred where the names shared initial or internal sounds, like Jimmy and Joanie or John and Bob. Physical resemblance between people was not a factor. Nor was gender.
The researchers conducted five separate surveys of more than 1,700 people. Some of the surveys included only college students; others were done with a mixed-age population. Some asked subjects about incidents where someone close to them – family or friend – had called them by another person’s name. The other surveys asked about times when subjects had themselves called someone close to them by the wrong name. All the surveys found that people mixed up names within relationship groups such as grandchildren, friends and brothers and sisters but hardly ever crossed these boundaries.
In general, the study found that undergraduates were almost as likely as old people to make this mistake and men as likely as women. Older people and women made the mistake slightly more often, but that may be because grandparents have more grandchildren to mix up than parents have children. Also, mothers may call on their children more often than fathers, given traditional gender norms. There was no evidence that errors occurred more when the misnamer was frustrated, tired or angry.

B.It hardly occurs across gender boundaries.
C.It is most frequently found in extended families.
D.It most often occurs within a relationship group.
4.Why do mothers misname their children more often than fathers?

B.They become worn out more often.
C.They communicate more with their children.
D.They generally take on more work at home.
In order to help cope with the vast number of student questions in the online class, Knowledge-Based Artificial Intelligence, Professor Ashok Goel of Georgia Tech developed an artificially intelligent teaching assistant. This online course is a core requirement of Georgia Tech’s online Master of Science in Computer Science program. Professor Goel already had eight teaching assistants, but that wasn’t enough to handle the vast number of daily questions from students.
Many students drop out of online courses because of the lack of teaching support. When students feel isolated or confused and reach out with questions that go unanswered, their motivation to continue begins to fade. Professor Goel decided to do something to remedy this situation and his solution was to create a virtual assistant named Jill Watson, which is based on the IBM Watson platform.
Goel and his team developed several versions of Jill Watson before releasing her to the online forums. At first, the virtual assistant wasn’t too great. But Goel and his team sourced the online discussion forum to find all the 40,000 questions that had ever been asked since the class was launched. Then they began to feed Jill with the questions and answers. After some adjustment and ample time, Jill was able to answer the students’ questions correctly 97% of the time. The virtual assistant became so advanced and realistic that the students didn’t know she was a computer. The students, who were studying artificial intelligence, were interacting with the virtual assistant and couldn’t tell it from a real human being. Goel didn’t inform them about Jill’s true identity until April 26. The students were actually very positive about the experience.
The goal of Professor Goel’s virtual assistant next year is to take over answering 40% of all the questions posed by students on the online forum. The name Jill Watson will, of course, change to something else next semester. Professor Goel has a much rosier forecast on the future of artificial intelligence than, say, Elon Musk, Stephen Hawking, Bill Gates or Steve Wozniak.

It is reported in the national press that a letter written by Charles Darwin in 1875 has been returned to the Smithsonian Institution Archives (档案馆) by the FBI after being stolen twice.
“We realized in the mid-1970s that it was missing,” says Effie Kapsalis, head of the Smithsonian Institution Archives. “It was noted as missing and likely taken by an intern (实习生), from what the FBI is telling us. Word got out that it was missing when someone asked to see the letter for research purposes,” and the intern put the letter back. “The intern likely took the letter again once nobody was watching it.”
Decades passed. Finally, the FBI received a tip that the stolen document was located very close to Washington, D.C. Their art crime team recovered the letter but were unable to press charges because the time of limitations had ended. The FBI worked closely with the Archives to determine that the letter was both authentic and definitely Smithsonian’s property.
The letter is in fairly good condition, in spite of being out of the care of trained museum staff for so long. “It was luckily in good shape,” says Kapsalis, “and we just have to do some minor things in order to be able to unfold it. It has some glue on it that has colored it slightly, but nothing that will prevent us from using it. After it is repaired, we will take digital photos of it and that will be available online. One of our goals is to get items of high research value or interest to the public online.”
It would now be difficult for an intern, visitor or a thief to steal a document like this. “Archiving practices have changed greatly since the 1970s,” says Kapsalis, “and we keep our high value documents in a safe that I don’t even have access to.”

A.It was recovered by the FBI.
B.It was put in the archives for research purposes.

D.It was purchased by the Smithsonian Archives.
2.What did the FBI do after the recovery of the letter?
A.They pressed criminal charges in vain. B.They kept it in a special safe.
C.They arrested the suspect immediately. D.They proved its authenticity.
3.What will the Smithsonian Institution Archives do with the letter according to Kapsalis?
A.Reserve it for research purposes only. B.Make it available online.
C.Keep it a permanent secret. D.Turn it into an object of high interest.
4.What can be a suitable title for the text?
A.A Letter by Charles Darwin Returns to the Smithsonian
B.The Smithsonian Tightens Security Measures
C.The Smithsonian Charges an Intern with Theft
D.The FBI Cracks a Criminal Case
