21、More than one-third of the world’s food is wasted or thrown away. This adds up to an unbelievable 1.3 billion tons of waste a year, most of which rots in landfills, emitting (排放) methane and contributing to climate change.
But one of the most promising and simple solutions lies in the problem itself: this wasted food — if composted ( 堆 肥 ) — could slow climate change and improve soil quality. When food waste break down in composting facilities or even in backyard compost piles, they don’t produce methane, and they result in carbon-rich soil. Higher quality soil also continues to absorb more carbon from the atmosphere, helping to fertilize plants and contributing further to fighting against climate change. Increasing the amount of carbon in the world’s soil by just 0.4 percent a year would stop the rise of carbon dioxide in the atmosphere. Returning one ton of organic matter to each hectare of soil would increase production of cereal crops each year by millions of tons.
While it is true that people can compost in their yards, community gardens, schools or even on their kitchen counters, larger-scale efforts, including infrastructure ( 基 础 设 施 ) and reward system for consumers, would take it to the next level. Imagine that consumers could just leave food leftovers in a bin for pickup, or drop them off at a local store, earning a few cents a bucket, just like what has been offered for recycling bottles or newspapers. Moreover, in the case of composting, the reward system would be sustainable because the end-product of compost can be sold to farmers.
There have been important steps recently toward keeping food waste out of landfills. But food still makes up the largest part of city landfills. Until that changes through increased composting, we are wasting a lot more than food. We are wasting the opportunity to slow climate change and ensure adequate future food supply for the world.
【1】What is the consequence of food waste?
A．Food shortage.
B．Climate change.
C．Less farming land.
D．Worse soil quality.
【2】What can we learn about the carbon-rich soil?
A．It emits large amounts of carbon.
B．It stimulates the production of carbon-dioxide.
C．It increases by 0.4 percent every year.
D．It benefits both plants and the environment.
【3】Which of the following does the author agree with?
A．Taking steps to ban landfills is urgent.
B．Composting on a large scale is helpful.
C．The end-product of compost is affordable.
D．It is just a matter of time before food waste stops.
【4】What is the best title for the text?
A．Where Landfills Go
B．Why Farmers Compost Food Waste
C．What Modern Farming Brings Us
D．How Wasted Food Could Save the Planet
22、China’s first domestically-developed passenger jet, C919, was delivered to China Eastern Airlines in Shanghai in late 2022. The plane, developed by the Commercial Aircraft Corporation of China (COMAC), was issued a certificate of airworthiness by the country’s aviation (航空) regulator, the Civil Aviation Administration of China.
Its certification signifies that China has the ability to independently develop world-class large passenger aircraft, and marks an important milestone for the country’s large aircraft industry. American aerospace manufacturer (制造商) Boeing and France-based Airbus have long dominated the commercial aircraft market. The C919, as part of China’s goal to develop homemade civil planes, is trying to compete with medium-range passenger planes from the two global giants.
The C919 narrow-body jet is China’s first trunk jetliner developed in accordance with international standards of airworthiness and with independent intellectual property rights. It has a wingspan of nearly 36 meters, a length of about 39 meters and a tail height of around 12 meters. The single-aisle plane has 158 to 192 seats. About 60 percent of the planes in the global civil plane industry, and 80 percent of the planes on the Chinese market, belong to this category in terms of the number of seats. Its aerodynamically-designed wings made from advanced metals and composites help improve fuel efficiency while reducing noise in the cabin. Its cockpit (驾驶舱), with the latest navigation technology and the so-called “fly by wire” computer controls, makes the C919 competitive with other narrow-body jets.
Narrow-body aircraft with 150 to 200 seats have been the most widely used planes in the global civil aviation market, and the C919 was designed and developed to meet the huge market demand for this type of planes. COMAC said the company is also preparing for gaining an airworthiness certificate from the European Aviation Safety Agency, aiming for the global market. And if the C919 could prove it’s safe, reliable and fuel-efficient in commercial operations, and has a competitive price, it will of course be welcomed by the global market.
【1】What does the C919’s certification mean?
A．Chinese aircraft manufacturing ha superior to American.
B．The C919 is the best-equipped commercial aircraft in the world.
C．China has the ability to develop medium-range passenger planes.

24、 Researchers at the University of Maryland have turned ordinary sheets of wood into transparent material that is nearly as clear as glass, but stronger and with better insulating properties(隔热性). It could become an energy efficient building material in the future.
Wood is made of two basic ingredients: cellulose, which are tiny fibres, and lignin (木质素),which is a glue-like material that bonds the fibres together to give it strength. The lignin also contains molecules called chromophores, which give the wood its brown color and prevent light from passing through.
Early attempts to make transparent wood involved removing the lignin, but this involved harmful chemicals, high temperatures and a lot of time, making the product expensive and somewhat fragile. The new technique is so cheap and easy that it could literally be done in a backyard.
Starting with pieces of wood a meter long and one millimeter thick, the scientists simply brushed on a solution (溶液)of hydrogen peroxide using an ordinary paint brush. When left in the sun, or under a UV lamp for an hour or so, the peroxide remove color from the brown chromophores but left the lignin undamaged, so the wood turned white. Next, they filled the wood with a tough transparent epoxy, which filled in the spaces in the wood and then hardened. This made the white wood transparent.
As window material, it would be much more resistant to accidental breakage. The clear wood is lighter than glass, with better insulating properties, which is important because windows are a major source of heat loss in buildings. It also might take less energy to produce clear wood because there are no high temperatures involved.
Transparent wood could become an alternative to glass in energy efficient buildings, or perhaps coverings for solar panels in harsh environments. There could be no end of uses.
【1】What is the second paragraph mainly about?
A．The classification of wood strength.
B．The characteristics of wood.
C．The causes of wood color.
D．The structure of wood.
【2】How did the researchers make wood transparent in the past?

B．By reducing chemicals.
C．By lowering the temperature.
D．By changing the experiment site.
【3】What is the function of the epoxy?
A．To make the wood stronger.
B．To take away the brown color.
C．To turn the wood transparent.
D．To fill the spaces in the wood.
【4】Which can be a suitable title for the text?
A．Replacing Glass with Wood
B．Turning Wood Transparent
C．Energy Saving Material
D．Eco-friendly Alternative
25、Many people learn at an early age to associate the color red with danger. So might it make sense to print medication ________ in red ink? And since the color blue is known to call to mind the freedom of open skies, might it help artists to ________ in a studio painted in that color? According to new research into how the brain reacts to ________ , the answer to both of these questions is yes. The study revealed that the color red seems to improve a subject’s attention to ________ , while blue appears to stimulate creativity—all without the subject realizing that his or her brain is being influenced.
“People are not ________ this effect at all,” marveled the study’s lead researcher Juliet Zhu, who studies the effects of environmental cues on behavior. To study the brain’s response to specific colors, Zhu’s team administered a series of ________ tests to college students. For most of the tests, the students were placed in front of a computer screen that was colored either red or blue.
The researchers found that when the screen was red, subjects performed better on detail-oriented tasks. In one test, ________ , students were asked to memorize a list of words. Zhu found that students who studied the list displayed on a red screen were able to recall more words than students who studied the list on a ________ screen.
In other tests, creative abilities seemed to be ________ by looking at the color blue. For instance, the students were asked to brainstorm potential uses for bricks. Students sitting in front of blue screens tended to come up with ideas that were ________ , such as “make a paperweight” and “build a pet scratching post.” Students sitting in front of a red screen, on the other hand, were more likely to list ________ uses for bricks, such as “build a house.”
Researchers concluded from the tests that seeing red causes people to take the extra time to think ________ when performing detail-oriented tasks, such as ________ , proofreading— and, of course, reading those all-important warning labels. ________ most people learn early in their development that red signifies potential danger, Zhu said, seeing red perhaps helps people to slow down in order to perform at their best in a potentially risky situation. Seeing blue, on the other hand, produces images of the sky, freedom and peace. Perhaps these images, researchers supposed, ________ feelings. “It’s really this learned association with these colors that drives these different motivations,” Zhu said.
