21、Just as our bodies produce waste every day — which is why we need to shower and use the toilet —our brains produce harmful waste proteins. But how can our brains “shower” themselves?
A 2013 study found the answer. Researchers at the US University of Rochester studied the brains of mice and discovered that they cleaned themselves while the mice slept. A kind of fluid in the brain, called cerebral spinal fluid (CSF脑髓液), was found to increase dramatically during sleep, washing away waste proteins that had been building up between braincells in waking hours.
“This study shows that the brain has different functional states when asleep and when awake,” Maiken Nedergaard, the lead researcher, told NBC News. It also explains why we can’t think clearly after a sleepless night while a good night’s sleep leaves us feeling sharp and refreshed.
Now a new study, published on October 31 in Science, digs a little deeper into our brains’ self-cleaning procedure. Instead of mice, this time humans were the test subjects.
Researchers at Boston University, US, monitored the brain waves of 13 healthy adults who were sleeping, using accelerated FMRI, which is capable of recording faster changes inside the brain than a regular FMRI machine. They found that every 20 seconds, blood flowed out of the brain, making room for a large amount of CSF to come in and “clean”. This cycle coincided (巧合) with the rhythm of the brains slow waves — an electrical activity that happens when we’ re in deep sleep.
It’s still unknown how these brain activities are connected. But the mere fact that they are connected is exciting enough, since it allows researchers to piece together possible new explanations for misunderstood diseases.
For example, slow-wave sleep has been proven to play a role in strengthening our memories. This may explain why people with Alzheimer’s often have fewer and weaker slow brainwaves. Based on this new study, there could be one more explanation for diseased brains: They are not clean.
Nedergaard, leader of the 2013 study, is also excited about the new findings. “Maybe the most important take-home message is that sleep is a serious thing,” she told Scientific American. “You really need to sleep to keep a healthy brain because it links electrical activity to a practical housekeeping ‘function’.”

22、No spacecraft will ever land on the sun. the sun is a flaming ball of gas that reaches thousands of degrees Fahrenheit. But next year, a ship from Earth will fly closer to it than any man made craft has flown before. The mission(任务)is a big development for scientists and, maybe, for everyone else.
In September 2018, NASA plans to launch the Parker Solar Probe. After a journey of nearly 90 million miles, it will fly within 3.8 million miles of the sun. within two months of launching, the probe is expected to reach the sun’s corona(日冕). That’s the sun’s outer atmosphere of gases.
Getting there won’t be easy. Designing a spacecraft tough enough to hold up to the sun’s heat has proved difficult. But that hasn’t stopped engineers from trying. Temperatures in the corona can reach millions of degrees. The probe will limit itself to regions where things get no hotter than 2,500oF. That’s still a heavy heat load for a spacecraft. But a 4.5-inch-thick heat shield(罩)will protect the probe’s camera and scientific instruments.
NASA says the data the probe collects could provide knowledge into the physics of stars. Our sun is special to us. But as a star, it’s rather common. So the better we understand how it works, the better we understand all stars of its mass and color.
Perhaps the most important is what the probe may show us about solar storms. During solar storms, charged particles stream through the solar system. They can disable communications satellites and shut down powder systems. One study has found that a very intense solar storm could cause up to $2 trillion in damage in the US alone. It could also black out the East Coast for a year.
Understanding solar storms might allow us to predict them and protect ourselves. That could make even a mission with a billion-plus price tag one of NASA’s great bargains.
【1】What can we learn about the probe?
A. It’ll fly closer to the sun that the previous ones
B. It’s the first man made instrument to fly to the sun
C. It’ll get to the core of the sun in nearly two months
D. It’ll fly about 3.8 million miles to reach the corona.
【2】What is the challenge for the engineers?
A. Directing the probe to collect data
B. Reducing the temperature of the probe
C. Building a shield against the heat
D. Limiting the probe to proper regions
【3】What might be the best title?
A. Exploring the stars B. Getting close to the sun
C. Designing a spaceship D. Protecting the earth
【4】Where does the value of the mission lie?
A. Monitoring satellites B. Exploring solar energy
C. Developing scientific instruments D. Forecasting solar storms
23、Why Walking in Nature Makes You a Better Worker?
We’re busy at work, distracted (注意力分散的) by technology and often live in urban environments far from wild spaces.【1】. The average American, for example, spends about 90% of their life indoors. But what happens if we maketime for an hour outside each day?
【2】. You’ll have to go out for a walk, which is beneficial if most of your day involves sitting in front of a screen. Research shows short breaks can improve work enthusiasm, and a quick break in natural light will deliver a shot of vitamin D.
There are also a lot of mental benefits when you are in nature-you are happy and your brain can make sense of life. “When people are all out in nature, even in urban nature, people tend to have more positive emotion and energy than when they are indoors.【3】,” said Lisa Nisbet, associate professor at Canada’s Trent University.
The idea that nature is good for us has been gaining grounds since the 1980s.【4】. Afterwards, shinrin-yoku, the Japanese concept, which is the practice of taking a short, leisurely visit to a forest for health benefits, followed that. Researchers of shinrin yoku have since found plenty of physical and mental benefits, while global studies suggest spending time in nature can, for example, restore our ability to focus, increase our creativity, and even help us live longer.
Of course, many of us live in cities with no ready access toforests or the wilderess.【5】. Various studies have shown that green environments in cities have beneficial effects.
A．We also don’t get out much
B．But it doesn’t have to be a forest
C．People can get to a forest for a hike
D．In other words, people are happier in nature
E．There are some obvious benefits when being outside
F．Green and blue spaces are better than busy city streets
G．First came the theory that humans have a basic desire to be connected with nature
24、Far out in the lake was a large wooden platform on which stood an improbably high diving board—a kind of wooden Eiffel Tower. It was, I’m sure, the county’s tallest wooden structure and no one had ever been known to jump from it.
So it was quite a shock when our teacher, Mr Milton, announced that he would dive off the high board that very afternoon.
Word of his questionable plan was already spreading through town as Mr Milton swam out to the platform.He was just a tiny, stick figure when he got there but even from such a distance the high board seemed almost to touch the clouds. Once at the top, he paced the enormously long board, then took some deep breaths and finally stood at edge. He was going to do it.
Several hundred people had gathered at the shore to watch. Mr Milton stood for quite a long time, then he raised his arms, took one massive bounce and launched himself into a perfect dive. It was beautiful. He fell with perfect style for what seemed minutes.The crowd fell silent.The only sound to be heard was the faint whistle of his body tearing through the air toward the water far，far below.
But about three quarters of the way down he seemed to have second thoughts and began suddenly to panic, waving his arms and legs like someone having a bad dream.When he was perhaps thirty feet above the water, he gave up on waving and spread his arms and legs wide，apparently hoping that it would somehow slow his fall.
It didn’t.
He hit the water at over six hundred miles an hour.The impact was so loud that it made birds fly out of their trees three miles away.I don’t think he entered the water at all.He just bounced off it, about fifteen feet back into the air. After that, he lay still on the surface, spinning like an autumn leaf.
He was brought to shore by two passing fishermen in a rowboat and placed on an old blanket where he spent the rest of the afternoon.Occasionally he accepted small sips of water, but otherwise was too shocked to speak. From head to toe, he was covered with deep red bruises.
...It was the best day of my life.
