21、Is it amazing to generate electricity by getting moisture(水汽)from the air surrounding you? Such devices, called MEG, have already been created with some regular items such as a piece of fabric. However, the researchers found it quite challenging with balancing and maintaining moisture content between where it shouldn’t be and where it is required to be.
To fix this problem, the team led by Tan Swee Ching from National University of Singapore created a new MEG.
One part of the fabric in their device is coated with a special gel(凝胶). This is what they called the wet region. The special water-absorbing gel is able to take in more than six times its original weight. This is the very thing used to harvest moisture coming from the air around. The other end of this device is the dry region, which doesn’t have the gel. They specifically designed the fabric this way to make sure that the area stays dry and that the water is trapped only in the wet region.
The wet-dry regions ensure water is maintained just in the wet area, even if this device is left in an open damp environment fora month. This demonstrates how effective the device is when it comes to maintaining its stable electrical output.
The MEG device also has immediate potential applications, one of which is to make a portable power source. “With this unique structure, the electric performance of our MEG device is significantly improved in comparison with the previous ones, thus making it possible to power many common electronic devices, such as health monitors and wearable electronics,” Tan said.
“The invention can be massively produced because it’s easy for factories to get their hands on commercially available raw materials. When it is perfected, many people can finally get their hands on this small, yet powerful tool that they can easily and readily apply in the devices used for their daily use,” Tan added.

22、I was born with a rare disease that prevented the normal growth of my right arm. I was heart-broken at school. Those cruel experiences won’t affect me now, but back then they struck me very hard.
My parents realised playing with Lego was a great way to improve my flexibility, so they bought me a set when I was five. I built planes and cars, and even a prosthetic (义肢的) arm, though I had already decided I didn’t need a prosthetic arm — it was very expensive, and I was doing just fine.
I made one because it’s fun. I have since made several new versions. And my latest model is the most advanced and comfortable. It has a control unit that can send and receive orders from sensors on the arm to the motors, with cables that contract like muscles.
A lot of people don’t have the ability to buy a prosthetic. I hate it when people have to pay up to €100,000 for a prosthetic. They shouldn’t pay that much — it’s not a luxury. My goal is to try to make some that more people can afford.
When I was 19, the parents of an eight-year-old boy got in touch to ask if I could build him a prosthetic. His arms and legs are underdeveloped as part of his condition, so I made two prosthetic arms using Lego units costing only €15. His smile when he used them for the first time was very encouraging.
To me, my creations don’t necessarily tell the story of how I overcame my condition with Lego; they’re about how I overcame the tough period almost every day at school.

23、For more than a decade, a team of researchers have studied the dynamics of the Greenland Ice Sheet as it responds to a warming climate. But while much of their focus has been on waters impacts on ice sheet change, their most recent research findings have overturned the order of their thinking. Meierbachtol, Harper and their team discovered that changes in the ice sheet have a real impact on the massive groundwater system underlying Greenland.
This latest discovery occurred thanks to a marriage of drilling techniques. International cooperators made an angled hole 650 meters through bedrock underneath a Greenland glacier (冰川)to measure groundwater conditions under the ice. Meanwhile, researchers drilled 32 holes from atop the glacier, through nearly a kilometer of ice, to measure water conditions at the area between ice and bedrock, which forms an important boundary controlling groundwater flow below. After drilling, the team fixed sensors in the ice column and at the ice sheet bed to measure ice dynamics and water conditions as water flows under the ice.
“By studying areas covered by ice 10,000 years ago, we have known that the huge mass and vast amounts of water from melting ice can impact the underlying groundwater,” Meierbachtol said. “It’s generally accepted that the groundwater is sleeping over decades to centuries and its response to ice sheet change is long: thousands of years. But what we’ve shown here is that it is immediate.”
This new understanding could have important subsequent effects on how Greenland’s thinning impacts the Arctic. The thinning ice could reduce the rate of groundwater flow to the ocean, changing the water temperature and salinity (盐度)balance that is important for ocean circulation (循环)patterns. “In thinking about the complex feedbacks from Greenland’s ongoing change, we have really ignored the groundwater component,” Harper said.
【1】How do the researchers feel about the result of the recent study?

A．It has a very large volume.
B．It is inactive for a long time.
C．Its component is complex.
D．Its temperature is changeable.
【4】Which of the following is a suitable title for the text?
A．Water Impacts the Greenland’s Ice Sheet
B．Longlasting Effects of Global Warming on the Arctic
C．Newly Discovered Groundwater Resources in Greenland
D．Greenland’s Groundwater Changes with Thinning Ice Sheet
24、I did a crazy thing last weekend. I signed my family up for a six-mile hike out in the Yunmeng Mountains in Huairou District, Beijing.
Ever since we arrived in Beijing two years ago, my family has never walked around in any Beijing park for longer than two miles. I had signed up on Beijing Hikers’ hike several times before, but had always backed out at the last minute because of my son and husband’s protest. This time, I was not getting out of it!
When we woke up early on Saturday morning, it was raining cats and dogs. My husband turned to me and said, “Perfect hiking weather!”
But, I wasn’t backing down. If the other hikers thought that the weather was safe for hiking, then we were going! I did not regret even when our tour bus drove right into the heavy rain. Luckily, the rain stopped before we entered the mountains.
For the hike I had packed various snacks. When one treat stopped providing motivation for my 6-year-old son to put one foot in front of the other, I would turn to another to keep him moving. After I ran out of snacks, the guide cleverly asked him to look out for the red ribbons(丝带) that the Beijing Hikers use to mark the trail, and allowed him to collect them for her. This trick helped keep him moving for the first five miles of the well-kept road along the White River. However, the last mile was almost vertical(垂直的). While the kid had been moving like a snail for most of the walking part, he became a mountain goat when it came to the vertical climb. He actually led the group alongside the guide, leaving me and my husband far behind! We couldn’t even see him through the trees, and could only hear his merry voice carried by the wind.
Just then I turned to my husband and asked whether we would do it again. He replied, “I might feel much better if I were lying in bed dreaming about this hiking.”

【3】What did the author’s husband imply in the last paragraph?
A．He loved hiking in the rain.
B．He was too sleepy to walk.
C．He preferred staying at home.
D．He didn’t have the final say.
【4】What can we know about the author according to the text?
A．She is romantic.

25、One day, while I was walking to work, I decided to bring some flowers that I had picked from my garden that morning. On the way, I _________ a stranger and presented the flowers to him with a smile card. _________ by the sense of joy I felt from giving flowers to another person, and may be _________ his day, I wanted to do it again.
When I got to my office, I had the _________ of anonymously (匿名) leaving flowers around the workplace. The impersonal (无人味) _________ of the building where I work makes me _________. It just feels a little boring sometimes, _________ it’s a nice building with great light. I _________ lots of people might feel the same way, so why not put a little _________ there, and throw in an inspirational quote (引言) while I’m at it? __________, who doesn't like flowers?
So, for the past month, I’ve been __________ flowers in a little cup on the sink in the bathroom. Each week, I __________ the flowers and the quote. It always feels __________ for me to read quotes like Henry David Thoreau’s “If one advances confidently in the direction of his dreams, he will meet with a __________ unexpected in common hours.” and Gandhi’s “The fragrance(香味) always __________ on the hand that gives the rose.” If anything, I figured, it at least makes me __________ each time I visit the bathroom.
Then today, when I walked in, I noticed __________ flowers in the cup, and a quote that someone else had written! It __________, “Be the change you wish to see in the world.” ------- Gandhi.This little act __________ me that, at the end of the day, we’re all just people with hearts __________ the various roles and different hats we may wear in the workplace.
I did a little dance and am smiling wide for the rest of the day!
