1 . Virtually, there is nothing that man cannot do. Only what he has to do is keep doing and doing without being discouraged. Success will come someday or other, though it may apparently be the conception about something that it cannot be done.
What the world-famous scientist Sir Isaac Newton had done by twelve years’ constant hard work was burnt out by his pet dog. But that could not discourage him a little.
All the great men in history have written their names in golden letters by means of perseverance.
A.Every action has its reaction. |
B.It is a unique precondition to success in life. |
C.In human life, perseverance plays a very important role. |
D.Their success will always remain as perfect examples to us. |
E.Columbus has left us an adventurous story of perseverance. |
F.The task that is easily done at the first attempt is undoubtedly very easy. |
G.He was able to do it again through years of hard work and perseverance. |
2 . From the moment we are born, we interact with the world through movement. We move our lips to smile or to talk. We extend our hand to touch. How does our brain remember this wide range of motions? How does it learn new ones? How does it make the calculations necessary for us to grab a glass of water, without dropping it, squashing it, or missing it?
Technion Professor Jackie Schiller from the Ruth and Bruce Rappaport Faculty of Medicine and her team examined the brain at a single-neuron (单神经元) level to shed light on this mystery. They found that calculation happens not just in the interaction between neurons, but within each individual neuron. It turns out that each of these cells is not a simple switch, but a complicated calculating machine.
This discovery, published recently in the Science, promises changes not only to our understanding of how the brain works, but better understanding of conditions ranging from Parkinson’s disease to autism. And if that isn’t enough, these same findings are expected to advance machine learning, providing inspiration for new architectures.
“We used to think of each neuron as a sort of whistle, which either rings, or doesn’t,” Prof. Schiller explains. “Instead, we are looking at a piano. Its keys can be struck at the same time, or in order, producing an infinity (无限) of different tunes.” This complex music playing in our brains is what enables us to learn and perform an infinity of different, complex and precise movements.
These same findings can also serve as an inspiration for the machine learning community. Deep neural networks, as their name suggests, attempt to create software that learns and functions somewhat similarly to a human brain. Although their advances constantly make the news, these networks are primitive compared to a living brain. A better understanding of how our brain actually works can help in designing more complex neural networks, enabling them to perform more complex tasks.

3 . Some 20 percent of adults are procrastinators (拖延症患者). Everyone might put off a task or two, but long-term procrastinators do it at home, at school, at work and in their relationships.
For years, researchers have focused on the personalities of people who procrastinate. The results suggest procrastinators may be impulsive (冲动), worriers and have trouble regulating their emotions. But procrastinators are not lazy. They’re actually very busy doing other things than what they’re supposed to be doing. Though procrastinators may think they perform better under pressure, studies have reported the opposite. And when deadlines are uncertain, procrastinators tend to delay their work.
When people put off a tough task, they feel good-in the moment. Procrastinating is a way to avoid the negative emotions linked to the task. But the relief it provides is only temporary, and many seek out ways to stop procrastinating.
In fact, most research today suggests procrastination is a behavioral pattern, which means it’s something you can change, regardless of whether you’re impulsive. What works best is still under research. Some scientists have reported success with time management. But the evidence for that is all over the map. That’s because poor time management is a symptom not a cause of procrastination.
For some procrastinators, seemingly obvious tips can work. Researchers advise students to simply put down their smartphones. Silencing notifications or studying in the library rather than at home can regulate distractions and keep people on task. But that won’t be enough for many people. Stubborn procrastinators may benefit from cognitive behavioral therapy (认知行为疗法). This type of therapy, which involves managing thoughts and emotions and trying to change behavior, seemed to be the most helpful. Still, not many studies have examined treatments, and there’s room for improvement.

4 . In a lot of other states in America, warm sunny days mean lazy afternoons are spent on the beach. In Oregon, people pack hiking shoes with their bathing suits. Here are 3 incredible hikes for you.
Cascade Head Preserve
Distance: 6.8 miles
Difficulty: Moderate
Nearest Town: Lincoln City
Managed by the international nonprofit The Nature Conservancy, the Cascade Head Preserve is an excellent hike that typically marks the division between the north and central Oregon coast. There are upper and lower trailheads (小道的起点), with about 3.4 miles of trails between the two.
Cape Lookout
Distance: 5 miles
Difficulty: Easy
Nearest Town: Tillamook
Of all the capes on the Oregon coast, Cape Lookout might be the most famous, projecting 1.5 miles into the ocean. Visitors can tackle the five-mile, round-trip hike to the tip of the cape where they can enjoy several incredible views over the Pacific Ocean. Separate trails lead down to South Beach and the Campground.
Clatsop Loop Hike
Distance: 3 miles
Difficulty: Easy
Nearest Town: Cannon Beach
There are several trails that traverse (横越) Tillamook Head at Ecola State Park, but the Clatsop Loop Hike is known for its breathtaking Cliffside views and quiet forested paths. Take the seaside trail from Indian Beach to the Hikers Camp, then take the forested path back.

Last Saturday, all the seniors of our school visits a digital exhibition. The exhibition was named “A Panorama of Rivers and Mountains 3.0”, what is a perfect combination of traditionally art techniques and innovative digital technology.
The exhibition hosting by the City Art Gallery, enjoyed huge popularity between us. The highly immersive experience allowed us admire one of the most treasured work of art from the Song Dynasty with our own eyes. The highlight was the real time interaction, enabling us to lose ourselves in the vast and beautiful scenery in the person. This experience will stick in your minds, for we felt the charm of both Chinese magnificent landscape or high tech.

When I was eight, my father bought me the new bike for my birthday. My brother offered to teach me how to ride. At first, they rode and let me watching. Then he explained me the skills of controlling the bike. Still puzzling, I got on the bike, but it doesn’t move as expected. I lost my balance and fall off the bike. At once I burst into tear because I saw blood on the ground. While I stood up, my left leg hurt bad. Later, I learned to ride a bike. But this experience told me that though some lessons were painful to learn them, yet we could benefit a lot.
