Here are some methods that can effectively help you learn.
Don't expect to learn much by just watching, listening or reading. Instead, try to build your own story. For example, you can be driven to a store 20 times and still not know the road. 1 ． .
Go over a piece of information repeatedly. Most of the information we absorb in a typical day is not only forgettable. 2 ． . Do you really want to remember forever what all the strangers you passed today on the sidewalk were wearing? So how does your brain know whether something should be put into your long-term memory or not? Repeat it over a period of time!
3 ． . If you try to go over it too late, the original memory will be nowhere to be found. But if you wait only a few minutes to review it, it's too quick for you to signal your brain to put it into long-term memory.
4 ． . Flashcards, whether they're physical or virtual, are a great way to do memory practice because they help space out attempts to remember, and you can come back to them easily periodically( 周期性地 ).
But you have to follow certain rules in order to make better use of the flashcards. The No.1 rule is that you need to guess the answer before looking at the card. Even if you think it is hopeless for you to remember, try. 5 ． .Wait long enough between practice sessions. You have to make it a struggle to remember.
A ． Actually, it should be quickly forgotten
B ． The second rule is that you need to make it hard
C ． Used in the right way, flashcards can be of great help
D ． Therefore, repetition is very important for long-term memory
E.But once or twice you try to drive there and you'll know the road by heart
F.Burning an idea into memory by going over it again and again in a single session
G.The key for repetition is that you can neither wait too long nor try to review it too fast
Find Your Adventure at the Space and Aviation( 航空 ) Center
If you’re looking for a unique adventure, the Space and Aviation Center (SAC) is the place to be. The Center offers programs designed to challenge and inspire with hands-on tasks and lots of fun.
More than 750,000 have graduated from SAC, with many seeking employment in engineering, aviation, education, medicine and a wide variety of other professions. They come to camp, wanting to know what it is like to be an astronaut or a pilot, and they leave with real-world applications for what they’re studying in the classroom.
For the trainees, the programs also offer a great way to earn merit badges( 荣誉徽章 ). At Space Camp, trainees can earn their Space Exploration badge as they build and fire model rockets, learn about space tasks and try simulated( 模拟 ) flying to space with the crew from all over the world. The Aviation Challenge program gives trainees the chance to earn their Aviation badge. They learn the principles of flight and test their operating skills in the cockpit( 驾驶舱 ) of a variety of flight simulators. Trainees also get a good start on their Wilderness Survival badge as they learn about water- and land-survival through designed tasks and their search and rescue of ＂ downed ＂ pilot.
With all the programs, teamwork is key as trainees learn the importance of leadership and being part of a bigger task.
All this fun is available for ages 9 to 18. Families can enjoy the experience together, too, with Family Camp programs for families with children as young as 7.
Stay an hour or stay a week — there is something here for everyone!

As data and identity theft becomes more and more common, the market is growing for biometric( 生物测量 ) technologies—like fingerprint scans—to keep others out of private e-spaces. At present, these technologies are still expensive, though.
Researchers from Georgia Tech say that they have come up with a low-cost device( 装置 ) that gets around this problem: a smart keyboard. This smart keyboard precisely measures the cadence( 节奏 ) with which one types and the pressure fingers apply to each key. The keyboard could offer a strong layer of security by analyzing things like the force of a user’s typing and the time between key presses. These patterns are unique to each person. Thus, the keyboard can determine people’s identities, and by extension, whether they should be given access to the computer it’s connected to—regardless of whether someone gets the password right.
It also doesn’t require a new type of technology that people aren’t already familiar with. Everybody uses a keyboard and everybody types differently.
In a study describing the technology, the researchers had 100 volunteers type the word “touch” four times using the smart keyboard. Data collected from the device could be used to recognize different participants based on how they typed, with very low error rates. The researchers say that the keyboard should be pretty straightforward to commercialize and is mostly made of inexpensive, plastic-like parts. The team hopes to make it to market in the near future.
1 ． Why do the researchers develop the smart keyboard?
A ． To reduce pressure on keys. B ． To improve accuracy in typing.
C ． To replace the password system. D ． To cut the cost of e-space protection.
2 ． What makes the invention of the smart keyboard possible?
A ． Computers are much easier to operate.
B ． Fingerprint scanning techniques develop fast.
C ． Typing patterns vary from person to person.
D ． Data security measures are guaranteed.
3 ． What do the researchers expect of the smart keyboard?
A ． It’ll be environment-friendly. B ． It’ll reach consumers soon.
C ． It’ll be made of plastics. D ． It’ll help speed up typing.
4 ． Where is this text most likely from?
A ． A diary. B ． A guidebook C ． A novel. D ． A magazine.
The 65-year-old Steve Goodwin was found suffering from early Alzheimer’s. He was losing his memory.
A software engineer by profession, Steve was a keen lover of the piano, and the only musician in his family. Music was his true passion, though he had never performed outside the family.
Melissa, his daughter, felt it more than worthwhile to save his music, to which she fell asleep each night when she was young. She thought about hiring a professional pianist to work with her father.
Naomi, Melissa’s best friend and a talented pianist, got to know about this and showed willingness to help.
“Why do this?” Steve wondered.
“Because she cares.” Melissa said.
Steve nodded, with tears in his eyes.
Naomi drove to the Goodwin home. She told Steve she’d love to hear him play. Steve moved to the piano and sat at the bench, hands trembling as he gently placed his fingers on the keys.
Naomi put a small recorder near the piano. Starts and stops and mistakes. Long pauses, heart sinking. But Steve pressed on, playing for the first time in his life for a stranger.
“It was beautiful.” Naomi said after listening to the recording. “The music was worth saving.”
Her responsibility, her privilege, would be to rescue it. The music was still in Steve Goodwin. It was hidden in rooms with doors about to be locked.
Naomi and Steve met every other week and spent hours together. He’d move his fingers clumsily on the piano, and then she’d take his place. He struggled to explain what he heard in his head. He stood by the piano, eyes closed, listening for the first time to his own work being played by someone else.
Steve and Naomi spoke in musical code lines, beats, intervals, moving from the root to end a song in a new key. Steve heard it. All of it. He just couldn’t play it.
Working with Naomi did wonders for Steve. It had excited within him the belief that he could write one last song. One day, Naomi received an email. Attached was a recording, a recording of loss and love, of the fight. Steve called it “Melancholy Flower”.
Naomi heard multiple stops and starts, Steve struggling, searching while his wife Joni called him “honey” and encouraged him. The task was so hard, and Steve, angry and upset, said he was quitting. Joni praised him, telling her husband this could be his signature piece.
Naomi managed to figure out 16 of Steve’s favorite, and most personal, songs. With Naomi’s help, the Goodwin family found a sound engineer to record Naomi playing Steve’s songs. Joni thought that would be the end. But it wasn’t.
In the months leading up to the 2016 Oregon Repertory Singers Christmas concert, Naomi told the director she had a special one in mind: “Melancholy Flower.”
She told the director about her project with Steve. The director agreed to add it to the playing list. But Naomi would have to ask Steve’s permission. He considered it an honor.
After the concert, Naomi told the family that Steve’s music was beautiful and professional. It needed to be shared in public.
The family rented a former church in downtown Portland and scheduled a concert. By the day of the show, more than 300 people had said they would attend.
By then, Steve was having a hard time remembering the names of some of his friends. He knew the path his life was now taking. He told his family he was at peace.
Steve arrived and sat in the front row, surrounded by his family. The house lights faded. Naomi took the stage. Her fingers. His heart.
