21、 The blue planet is going green. Since the 1980s, satellite images have shown that leafy cover across the globe has grown by 2.3 percent per decade. A new study, published on February 11 in Nature Sustainability, helps explain why. One main driver is the “fertilization (施肥) effect”, brought about by humans burning fossil fuels. As CO2 increases in the atmosphere, this increases photosynthesis (光合作用) — as long as water, light, and nutrients are not limited. When plants take up more of the gas, they produce more food and new leaves.
But researchers also found another cause for the change in color: planting more crops and trees. China and India, the two most populous countries on Earth, have contributed about a third of the greening seen since 2000, mainly in the form of forests and farms.
In this most recent paper, scientists at Boston University took a closerlook at this greening trend. They used data from NASA’s Moderate Resolution Imaging Spectroradiometer (光谱辐射计), or MODIS, which uses advanced satellite technology to document the Earth’s surface on a near-daily basis. From 2000 to 2017, the researchers looked at the change in greenness in plant-covered regions, including croplands, forests, and grasslands.
The satellite data showed that globally, one-third of plant-covered areas are greening, while only five percent are browning. “Human land use management in many regions is more important than those indirect factors [ of climate change and CO2 fertilization ],” says Chi Chen, lead author of the study. “China and India, two developing countries, contribute the most in the increase in leaf area.” According to the study, the two nations contributed more greening relative to their plant-covered area than other countries.
While only 6.6 percent of the world’s vegetated area is in China, the country is responsible for 25 percent of the increase in global greening. The study found that most of China’s greening occurred in its forests, with croplands also contributing.

【2】What does Chi Chen think is the direct factor of the global greening?

A.China’s forests and grasslands.
B.India’s forests and farmlands.
C.China’s and India’s grasslands and croplands.
D.China’s and India’s forests and croplands.

23、A race is on in solar engineering to create almost impossibly-thin, flexible solar panels. Stanford University researchers announced they have achieved record efficiencies in a promising class of new materials—which can be thinner than a piece of paper.
According to the study published in the journal Nature Communications, it uses a new material called “transition metal dichalcogenides” (TMDs). They absorb incredibly high volumes of sunlight that reach their surface compared to other solar materials.
“Imagine an autonomous drone (无人机) that powers itself with a solar panel atop its wing that is less than six micrometers thick.” said Koosha Nassiri Nazif, co-lead author of the study.
Slimming down is necessary because the king of solar materials, silicon, is much too heavy, large and rigid for applications where flexibility, lightweight and high power are important and excellent.
While TMDs hold great promise, research experiments to date have struggled to change more than 2% of the sunlight they absorb into electricity. But the scientists believe they could practically reach 27% efficiency with electrical improvements. That would be comparable with today’s top solar panels, silicon included.
Nazif told Forbes that the new materials are great candidates for next-generation electronics and solar cells. Chipmakers like Intel and the Taiwan Semiconductor Manufacturing Company are already considering TMDs for their future technology. They could be used in a variety of mobile applications, including self-powered wearable devices and sensors, as well as giving a boost to lightweight airplanes and electric cars.
The ultra-thinness does come with engineering challenges, primarily in mass production. When transferring such a layer of TMD to a flexible, supporting material, the TMD layer is frequently damaged.
But the team thinks it is possible to overcome these challenges. Should they succeed, it could change solar power as we know it. “Silicon makes up 95 percent of the solar market today.” Nazif told Forbes. “This is why we aren’t seeing these applications for solar cells today; TMDs are going to change the landscape.”
【1】What is the biggest advantage of TMDs now?
A．They have the quality of remarkable thinness.
B．They can efficiently turn sunlight into energy.
C．They are comparable to top silicon panels.
D．They have excellent ability to reflect sunlight.
【2】What does Nazif stress in paragraph 6?
A．The appeal of TMDs to chipmakers.
B．The expectation for future tech.
C．The wide applications of solar energy.
D．The future prospects of TMDs.
【3】What can we expect of new solar panels in the future?
A．They could power all mobile devices.
B．They could be a competitive alternative.
C．They will revolutionize the energy market.
D．They will be produced on a large scale soon.
【4】Which of the following is the best title of this passage?
A．Most Efficient Solar Panels Have Hit the Market.
B．Stanford Scientists Develop a New Green Material.
C．TMDs Could Be Used for Lightweight Solar Panels.
D．Challenges Are to Be Overcome to Promote TMDs.
24、 One of the major producers of athletic footwear, with 2002 sales of over $10 billion, is a company called Nike, with corporate headquarters (总部) in Beaverton, Oregon. Forbes magazine identified Nike's president, Philip Knight, as the 53rd-ichest man in the world in 2004. But Nike has not always been a large multimillion-dollar organization. In fact, Knight started the company by selling shoes from the back of his car at track meets,
In the late 1950s Philip Knight was a middle distance runner on the University of Oregon track team, coached by Bill Bowerman. One of the top track coaches in the U, S., Bowerman was also known for experimenting with the design of running shoes in an attempt to make them lighter and more shock-absorbent. After attending Oregon, Knight moved on to do graduate work at Stanford University; his MBA thesis was on marketing athletic shoes. Once he received his degree, Knight traveled to Japan to contact the Onitsuka Tiger Company, a manufacturer of athletic shoes. Knight convinced the company's officials of the potential for its product in the U. S. In 1963 he received his first shipment of Tiger shoes, 200 pairs in total.
In 1964, Knight and Bowerman contributed $500 each to form Blue Ribbon Sports, the predecessor of Nike. The first employees hired by Knight were former college athletes. The company did not have the money to hire “experts”, those knowledgeable in the field. In its early years the organization operated in an unconventional manner that characterized its creative approach to the industry. Communication was informal; people discussed ideas and issues in the hallways, on a run, or over a beer. There was little task differentiation. There were no job descriptions, rigid reporting systems, or detailed rules. The team spirit and shared values of the athletes on Bowerman's teams carried over and provided the basis for the style of management that characterized the early years of Nike.
【1】Which of the following statements is true?
A．Nike is the most popular athletic brand.
B．Nike developed from Blue Ribbon Sports.
C．Knight in the 53rd richest man in the world.
D．Knight was once a long-distance runner.
【2】Why did Knight travel to Japan?
A．To advertise his product.
B．To seek for financial support
C．To apply for the selling right.
D．To learn their management.
【3】What difficulty did Nike face in its early stage?
A．A lack of professionals.
B．A lack of creativity.
C．A lack of team spirits.
D．A tack of communication.
