No one knew Prince Edward Street as well as Pierre Dupin. He had delivered milk to the families on the street for thirty years. For the past fifteen years a large white horse named Joseph pulled his milk wagon. Joseph was a gentle horse with beautiful spirit shining out of its eyes, so Pierre named him after Saint Joseph.
Every morning at five, Pierre arrived at the milk company's stables to find Joseph waiting for him, Pierre would call, “Good morning, my old friend.”， as he climbed into his seat, while Joseph turned his head toward the driver. And the two would go proudly down the street. Without any order from Pierre, the wagon would roll down three streets. Then it turned right for two streets, before turning left to Saint Catherine Street. The horse finally stopped at the first house on Prince Edward Street. There, Joseph would wait perhaps thirty seconds for Pierre to get down off his seat and put a bottle of milk at the front door.
Pierre knew every one of the forty families that got milk. The cooks knew that Pierre could not read or write; so, instead of leaving orders in an empty milk bottle, they simply sang out if they needed an extra bottle.
Pierre also had a wonderful memory. When he arrived at the stable he always remembered to tell Jacques, the foreman(领班) of the stables, “The Pacquins took an extra bottle this morning; the Lemoines bought a pint of cream ...” Most of the drivers had to make out the weekly bills and collect the money. But Jacques, liking Pierre, never asked him to do this.
One day the president of the milk company came to inspect the early morning milk deliveries.Jacques pointed to Pierre and said:”See how the horse listens and how he turns his head toward Pierre? See the look in that horse's eyes? You know, I think those two share a secret. I have often felt it. He is getting old. Maybe he ought to be given a rest, and a small pension.”
“But of course，” the president laughed. “He has been on this job now for thirty years. All who know him love him. Tell him it is time he rested. He will get his pay every week as before.”
But Pierre refused to leave his job. He said his life would be nothing if he could not drive Joseph every day. “We are two old men，” he said to Jacques. “Let us wear out together. When Joseph is ready to leave, then I too will do so.”
Then one cold morning Jacques had terrible news for Pierre. Jacques said，”Pierre, your horse, Joseph, didn't wake up. He was very old, Pierre.” Jacques said softly. “He is over in his stall, looking very peaceful. Go over and see him.” Pierre took one step forward, then turned. “No ... no ... I cannot see Joseph again. You ...， you don't understand, Jacques.”
For years Pierre had worn a large heavy cap that came down low over his eyes.It kept out the bitter cold wind. Now, Jacques looked into Pierre's eyes and he saw something that shocked him. He saw a dead, lifeless look in them.
“Take the day off, Pierre，” Jacques said. Pierre walked to the corner and stepped into the street.There was a warning shout from the driver of a big truck ... there was the screech(尖锐的刹车声) of rubber tires as the truck tried to stop. But Pierre heard nothing.
Five minutes later a doctor said, “He's dead ...， killed instantly.”
“I couldn't help it，” the truck driver said. “He walked in front of my truck. He never saw it, I guess. Why, he walked as though he were blind.”
The doctor bent down. “Blind？Of course, this man has been blind for five years.” He turned to Jacques, “Didn't you know he was blind？”
“No ...no ...” Jacques said softly. “None of us knew. Only one ... only one knew－a friend of his, named Joseph ... It was a secret, I think, just between those two.”

The latest IPCC report does not mince words(直言不讳地) about the state of our planet: we must act now to achieve global change at a scale that has “no documented historical precedent(先例)” in order to avoid the climate disaster that would result from a 2 degree C rise in average global temperature. Climate change already affects the world's most helpless people including poor rural communities that depend on the land for their livings and coastal communities. Indeed, we have already seen the clear asymmetry(不对称) of suffering resulting from extreme weather events, such as hurricanes, floods, droughts, wildfires and more.
So far, advocates and politicians have tended to focus on reducing fossil fuel(矿物燃料) consumption through technology and/or policy, such as a sharp carbon tax, as climate solutions. These proposals are, of course, essential to reducing manmade carbon emissions(排放)-71 percent of which are produced by just 100 fossil fuel companies.
Yet the international focus on fossil fuels has overshadowed(使......显得不重要) the most powerful and cost-efficient carbon-capture technology the world has yet seen: forests. Recent scientific research confirms that forests and other “natural climate solutions” are absolutely essential in reducing climate change. In fact, natural climate solutions can help us achieve 37 percent of our climate target, even though they currently receive only 2.5 percent of public climate financing.
Forests' power to store carbon dioxide through the simple process of tree growth is staggering:_one tree can even store an average of about 48 pounds of carbon dioxide in one year. Recent research show undamaged forests are capable of storing the same amount of the carbon dioxide emissions of entire countries such as Peru and Colombia.
For this reason, policy makers and business leaders must create and strengthen ambitious policies to prevent deforestation, and support the sustainable management of standing forests in the fight against climate change. Protecting the world's forests ensures they can continue to provide essential functions aside from climate stability, including producing oxygen, filtering water and supporting biodiversity. Not only do all the world's people depend on forests to provide clean air, clean water，oxygen, and medicines, but 1.6 billion people rely on them directly for their livelihoods.
1.According to the passage, climate change ________.
A. will surely achieve at a scale that is more serious than ever before
B. will only affect people living in the poorest rural regions
C. is likely to lead to more frequent extreme weather events
D. is entirely determined by fossil fuel consumption
2.What's the finding of the new research?
A. Reducing fossil fuels is the most powerful and cost-efficient technology.
B. Forests are vital to reducing climate change due to their storage power.
C. Most of our climate targets can be accomplished with the help of natural climate solutions.
D. Natural climate solutions have proved less efficient than conventional solutions.
3.The underlined word “staggering” in Paragraph 4 means ________.
A. astonishing B. speeding C. embarrassing D. shrinking
4.What's the author's purpose of writing this article?
A. To compare two different approaches to dealing with climate change.
B. To argue against the view that focus on fossil fuels reduction counts.
C. To urge scientists to do more research into natural climate solutions.
D. To point out forests are the most powerful weapon for fighting climate change.
We've all heard the saying: practice makes prefect! In other words, acquiring skills takes time and effort. But how exactly does one go about learning a complex subject such as tennis, calculus, or even how to play the violin? An age-old answer is: practice one skill at a time. A beginning pianist might rehearse scales(音阶) before chords(和弦). A young tennis player practices the forehand before the backhand. Learning researchers call this “blocking”， and because it is common and easy to schedule, blocking is dominant in schools, training programs, and other settings.
However another strategy promises improved results. Enter “interleaving”， a largely unheard-of technique that is catching the attention of cognitive(认知) psychologists and neuroscientists. Blocking involves practicing one skill at a time before the next (for example, “skill A” before “skill B” and so on, forming the pattern “AAABBBCCC”), while in interleaving one mixes practice on several related skills together (forming for example the pattern “ABCABCABC”).
Over the past four decades, a small but growing body of research has found that interleaving often outperforms blocking for a variety of subjects, including sports and category learning. Yet there have been almost no studies of the technique in unplanned, real world settings-until recently. New research in schools finds that interleaving produces dramatic and long-lasting benefits for an essential skill: math. Not only does this finding have the potential to transform how math is taught, it may also change how people learn more generally.
Researches are now working to understand why interleaving produces such impressive results. One important explanation is that it improves the brain's ability to tell apart between concepts. With blocking, once you know what solution to use, or movement to do, the hard part is over. With interleaving, each practice attempt is different from the last, so rote(死记硬背) responses don't work. Instead, your brain must continuously focus on searching for different solutions. That process can improve your ability to learn critical features of skills and concepts, which then better enables you to select and produce the correct response.
A second explanation is that interleaving strengthens memory associations. With blocking, a single strategy，temporarily held in short-term memory, is sufficient. That's not the case with interleaving-the correct solution changes from one practice attempt to the next. As a result, your brain is continually engaged at regaining different responses and bringing them into short-term memory. Repeating that process can strengthen neural connections between different tasks and correct responses, which improves learning.
Both of these accounts imply that increased effort during training, either to discriminate correct responses or to strengthen them, is needed when interleaving is used. This corresponds to a potential drawback of the technique, namely that the learning process often feels more gradual and difficult in the beginning. However, that added effort can have better, longer-lasting results.

A. Studying related skills together has many impressive results.
B. Learning relevant skills together contributes to people mastering skills quickly.
C. Focusing on different skills at a time saves people time and efforts in the beginning.
