Burning coal to provide energy adds planet-warming carbon dioxide, or CO2, to Earth’s atmosphere. As the planet heats up, experts warn that simply cutting greenhouse gas emissions (排放) will not be enough to avoid possibly disastrous levels of global warming. CO2 must also be obliterated from the atmosphere, they say.
Existing experimental machines that remove CO2 directly from the air are too costly to be widely used. But a new report from the U.S. National Academy of Sciences, Engineering and Medicine says effective carbon-removal technology already exists. It is not costly, or even complex science. It’s forests.
The report explains that planting trees and overseeing forests are cost-effective ways to clean the air. They also work well across large areas. Forests used to cover much of the Appalachian Mountains in the eastern United States. In the state of West Virginia, a kind of mining known as strip mining (露天开采) left the land there bare, without trees. Now experts are working to bring back the forests that once covered much of the state.
West Virginia’s Monongahela National Forest is home to a rare group of trees. They are called virgin (原始的) woods; they have never been touched by humans. Shane Jones, a biologist with the U.S. Forest Service, says the trees there were missed by mistake when the surrounding forest was cut down for wood many years ago. That mistake turned out to be a good thing; red spruce (云杉) forests such as those in the Monongahela are extremely effective at taking CO2 out of the atmosphere and locking it into the soil.
Experts say, nature offers powerful tools to fight climate change.

It was about 10:15 p.m., when Janice Esposito arrived at the Bellport train station, New York, jumped into her Honda Odyssey, and began the 20-minute drive home. She’d just returned from visiting her mother. When she turned left on Montauk Highway, out of nowhere a car T-boned her minivan, forcing her backward some 100 feet onto the railroad tracks. She sat in the minivan, bruised (挫伤) but mostly shocked.
As it happened, Pete DiPinto, a volunteer firefighter and retired teacher, 64, was getting ready for bed. When he heard the noise of metal on metal and broken glass coming from not far outside his bedroom window, he grabbed a flashlight and, still dressed in his pajamas (睡衣), ran out of the door. “Any firefighter would have done that,” he later said. “We’re always on duty.”
The first car he came upon was the one that had hit Esposito. Once concluding the driver was OK, DiPinto looked around and spotted Esposito’s minivan straddling (横跨) the railroad tracks. And then he heard the bells signaling an oncoming train.
DiPinto dashed to the minivan and struck on the driver’s side window. She just looked at him, her eyes unfocused. “I don’t know where I am,” she said. “Honey, you’re on the railroad tracks,” DiPinto shouted. “We have to get you off right now!” He pulled on the handle, but the door was jammed shut. The heavy train, traveling at 65 miles per hour, was whistling toward them. DiPinto ran to the passenger side and threw open the door. He pushed aside the deflating (放气) airbags, grabbed Esposito’s arms, and pulled her across the seat and helped her out to safety behind a signal box a few feet away. Within six seconds, the train crashed into the minivan. “It was like a Hollywood movie,” DiPinto told reporters the next day.
The Ambulance chief told CBS New York, “The hero arrived in pajamas, not in a fire truck.”

Time Management
What time is it? Most people are pretty accurate in their answer. And if you don’t know for sure, it’s very likely that you can find out. 1.; there may be clock on the wall, desk, or computer screen; or maybe you’re riding in a car that has a clock in the dashboard (仪表板).
2. even if you don’t have a timepiece of some sort nearby. Humans have an internal clock that regulates the beating of our heart, the pace of our breathing, the discharge of chemicals within our bloodstream, and many other bodily functions.
3.. Even if we ignore it, it’s still going by ticking away, second by second, minute by minute, hour by hour. So the main issue in using your time well is, “Who’s in charge?” 4.. Or we can take control of it and make it our partner.
By taking control of how you spend your time, you’ll increase your chances of becoming a more successful student. Perhaps more importantly, the better you are at managing the time you devote to your studies, the more time you will have to spend on your outside interests.
The aim of time management is not to schedule every moment so we become slaves of timetable that governs every waking moment of the day. 5.. Rather than letting the day go by, largely without our awareness, what we are going to discuss next can make us better able to control time for our own purposes.
A.We are the master of time
B.Your body keeps its own beat
C.You can find timepiece everywhere
D.There may be a watch on your wrist
E.Time is something from which we can’t escape
F.Instead, the aim is to inform us how we use time
G.We can allow time to slip by and let it be our enemy
The Notre Dame (巴黎圣母院) fire has been put out, but its wooden roof have been largely damaged. The terrible accident causes a sudden sharp pain to people around the world, “What a pity that we cannot see the damaged parts of the wonder anymore.”
But the good news is that there is at least one way of seeing them, namely via a video game called Assassin's Creed: Unity. In this game, the player can travel to one city after another and enter the buildings exactly like what they are in reality, and see Notre Dame as it was before the fire. In addition, with VR technology, which is already quite mature, one can even look around the undamaged Notre Dame as if it is still there. Maybe digital technology could help to better protect architectural cultural heritage.
The idea of digitizing ancient buildings, making digital models of them so their data can be saved, dates back to the 1990s and the necessary technology has continued to advance since then. By scanning the ancient buildings with lasers, building 3D models with hundreds of images, as well as measuring everything precisely, engineers can make a copy as “same” as the real one.
As computers and smartphones are hugely popular，the digital replica or digital copy has great pratical value. First, it allows tourists to feel the cultural relics without touching them, which helps protect them. The virtual tour of Dunhuang Grottoes in Gansu Province is a good example of this as tourists can view the paintings without standing near them. Furthermore, it can make the digitized cultural relics more famous by spreading awareness about them via the Internet. In 2000, a virtual tour of the Great Wall became very popular at the Hannover World Expo, which increased the number of foreign tourists visiting it in the following years. Above all, it preserves all the information of the cultural relics. Even if the original ones are damaged one day, people can still know what they were like and can build a replica if desired.
Time is the biggest problem to architectural heritage. Maybe we will have better technologies in the future，but the digital technology offers a practical way to preserve architectural cultural heritage at the moment.
