21、 The electricity bill for an average family with 2 children is worth about 1 full salary per year, but the revolutionary EcoVolt could put 50% of that money back into your pocket.
In 2017, a revolutionary new product called EcoVolt hit the market. Initially it was separated from the general public, all because it offered the opportunity for average families to save up to 50% of their monthly energy costs. EcoVolt is a small, simple, affordable, and easy to use plug in unit that stops unnecessary power from entering the electrical cables and overloading the network, EcoVolt is the utility (公用事业) provider' s best-kept secret. They 've been trying to hide it from the everyday power consumer and even have banned the sale of it in retail shops —just to maximize their profit. However, thanks to the internet, the secret is now out, and everyday customers are now attaining the rewards of less power consumption overall, as well as less power used by household appliances. Your household appliances (家用电器) may last longer than previously. Basically, EcoVolt provides the opportunity for you to save between 30 and 50 percent on your energy bill. That's a phenomenal saving and leaves few questions as to why this has been hidden from consumers.
The benefits of EcoVolt are huge, and researchers are convinced this device could spell the end of unaffordable power bills that can cripple the average wage earner at the end of the month. Scientists initially spent many months trying to expose its efficiency, but those studies now prove that EcoVolt should be common in every household.
It's easy to connect, simply by plugging it into your wall, and it's suitable for both standard homes and apartments connected to a power grid (电网). It also has a counter which shows how you're making more efficient use of your energy, all the while allowing you to gain the rewards of a more everlasting household appliance lifecycle.

22、The confidence people place in science is frequently based not on what it really is, but on what people would like it to be. When I asked my students how they would define science, many of them replied that it’s an objective way of discovering certainties about the world. But science cannot provide certainties.
Actually, doubt and science often go hand in hand. Science, when properly functioning, questions accepted understandings and brings both new knowledge and new questions —not certainty. Doubt does not create trust, nor does it help public understanding. So why should people trust a process that seems to require a troublesome state of uncertainty without always providing solid solutions?
As a historian of science, I would argue that it’s the responsibility of scientists and historians of science to show that the real power of science lies precisely in what is often regarded as its weakness: its drive to question and challenge accepted understandings. Indeed, the scientific approach requires changing our understanding of the natural world whenever new evidence arises from either experimentation or observation. Scientific findings are temporary understandings that involve the state of knowledge at a given moment. In the long run, many of them are challenged and even overturned. Doubt might be troubling, but it pushes us towards a better understanding. Certainties, reassuring as they may seem, prevent the scientific process.
Scientists understand this, but in the dynamic between the public and science, there are two opposite misconceptions (误解). The first is a form of blind scientism — a belief that science is unquestionable and has the capacity to solve all problems. Such an idealized representation actually ignores the universal existence of controversy, conflict and error at the very heart of the scientific world.
【1】What’s the real power of science according to the author?
A.It provides solid solutions.
B.It defends accepted understandings.
C.It discovers certainties about the world.
D.It keeps bringing questions and challenges.
【2】What does the underlined word “reassuring” probably mean?
A.Disappointing.
B.Surprising.
C.Comforting.
D.Challenging.
【3】What may be the belief of the second misconception?
A.Science is unchallengeable and a cure-all.
B.Science is unreliable and of little use.
C.Science is objective but impractical.
D.Science is doubtful but useful.
【4】What can be the best title for the text?
A.Why Is Doubt Vital to Science?
B.Why Should We Trust Scientists?
C.What Is the Weakness of Science?
D.What Is Scientists’ Responsibility?
23、The benefits of taking a nap.
Naps can charge your brain’s batteries
Taking a nap may make you more alert for the period right after you wake up and maybe hours into the day. A short sleep may also make you feel more relaxed.
You’ll have lower risk for heart problems
Taking a nap once or twice a week could lower the risk of heart attacks or strokes, according to a 2019 study published in the journal Heart.
After tracking more than 3,400 people between the ages of 35 and 75 for slightly more than five years, the researchers found that those who indulged in occasional napping -- once or twice a week, for five minutes to an hour -- were 48% less likely than those who didn’t nap to experience a heart attack, stroke or heart failure.
It might even help you get into shape
A 2020 study focusing on women found the more sleep-deprived the women were, the more likely they were to consume added sugar, fatty foods and caffeine.
A lack of quality sleep could lead to overeating because inadequate sleep is believed to stimulate hunger and suppress hormone signals that communicate fullness. The findings were important because women are at high risk for obesity and sleep disorders, the researchers said, which can both be driven by a high intake of food. Napping has been found to improve the overall quality of even nighttime sleep.
And boost your creativity
The right side of your brain might experience a mental spark during a nap, research has suggested. The right side is the hemisphere most associated with creative tasks, such as visualization and thinking, while the left is more analytic.
Researchers monitoring the brain activity of 15 people found that the right side of their brain communicated busily with itself as well as with its left counterpart. The left side of the brain, however, remained relatively quiet. In a January 2020 study of 2,214 Chinese adults ages 60 and older, participants who took afternoon naps for five minutes to two hours showed better mental agility than those who didn’t nap.
【1】What was the study in 2019 based on?
A.sleep time
B.subject age
C.study size
D.sleep rate
【2】Accordingto the 2020 study, the sleep-deprived women like eating ________ .
A.fruit and sea food
B.vegetable and wine
C.dessert and coffee
D.noodles and snacks
【3】How did the author develop the last paragraph?
A.By description.
B.By making comparison.
C.By showing figures.
D.By offering an example.
24、There has been a lot of publicity (宣传) recently surrounding 5G, the next generation of wireless technology for the world. But what is this technology and how might it change our lives?
What is 5G?
5G stands for fifth generation, meaning the next step in the progression of technology to replace the current 4G system. 4G was the replacement for 3G, which came after 2G, and so on. These systems are wireless computer networks. Earlier “G” systems were designed to improve mobile communication operations. Each new technology brought major improvements in speed and greatly increased network capacity. The new 5G system promises more of the same. It is expected to permit more users to do more things-at a faster rate. Higher internet speeds and larger network capacity should result in better performance for device users connected to 5G. However, technology experts say there is a major way that 5G is different than the earlier systems. It will move well beyond mobile network technology to affect many more devices and industries than other “G” versions.
When will it be available?
Before we can all use 5G, wireless companies and phone makers will have to complete and deploy (部署) a whole new system. New phones and communication equipment must be built. American wireless companies have been preparing for the new system for some time. They have been creating new network equipment and buying broadcasting space to carry 5G signals. They have built news G antennas(天线)to serve American cities and towns. Wireless providers will invest at least $275 billion n 5G-related networks in the United States, the industry group CTIA reported. The first U.S, launch of 5G is expected to happen sometime this year. Industry experts expect it will take a few more year to go nationwide. It will take even longer to reach rural areas. China is expected to launch 5G sometime in 2020, while European nations are likely to build their systems more slowly over time.
【1】Which system is widely used nowadays?
A.5G.
B.2G.
C.3G
D.4G.
【2】Which of the following is NOT 5G system’s advantage to the other Gs?
A.It will allow more users to do more things.
B.The internet speed will be much higher.
C.The users will spend much less money on it.
D.It will affect more devices and industries
【3】What can we learn from the last paragraph?
A.5G system has nothing to do with phone makers.
B.There is much work to do before 5G comes into use.
C.New phones will be much smarter than those used now.
D.4G system will be stopped as soon as 5G comes into use.
【4】In which order will the following countries use 5G system according to the passage?
A.USA→China→European nations.
B.China→USA→European nations.
C.USA→European nations→China.
D.European nations→China→USA.
25、 Today we continue our series on ecology and conservation with a look at a particularly endangered member of the black bear family. One in ten black bears is ________ born with a white coat, which is the result of a/an ________ gene that surfaces in a few. Local people have named it ‘the spirit bear’. And according to the legends of these communities, its snowy fur brings with it a special power. Because of this, it has always been highly ________ by them—so much that they do not speak of seeing it to anyone else. It is their way of protecting it when strangers visit the area.
The white bear’s ________ is quite interesting. The bear’s strong relationship with the old-growth rainforest is a complex one. The white bear relies on the huge centuries-old trees in the forest in many ways. ________, the old-growth trees have extremely long roots that help prevent erosion (腐蚀) of the soil along the banks of the many fish streams. Keeping these banks undamaged is important because these streams are home to salmon, which are the bear’s main food ________. The bear’s feeding habits nurture the forest ________. As the bears eat the salmon, they abandon the skin and bones in great amounts on the forest floor, which provide vital nutrients. These produce vegetation that ________ thousands of other types of life forms, from birds to insects and more.
Today, the spirit bear lives off the coast of the province of British Columbia on a few islands. There is great concern for their survival since it is estimated that less than two hundred of these white bears remain. The best way to protect them is to make every effort to preserve the ________ balance of their forest environment—in other words, their ecosystem.
The greatest ________ to the bear’s existence is the loss of its habitat. Over many years, logging companies have stripped the land by ________ a large number of trees. In addition, they have built roads which have fractured the areas where the bear usually ________, and many hibernation sites have also been lost. The logging of the trees along the streams has damaged the places where the bears fish. To make matters worse, the number of salmon in those streams is declining because there is no legal ________ on fishing at the moment.
All these ________ have a negative impact on the spirit bear’s very existence, which is made all the more fragile by the fact that reproduction among these bears has always been ________ low. While it is important to maintain the spirit bear’s habitat, there also needs to be more emphasis on its expansion. The move is justified as it will also create space for other bears that are losing their homes.

26、阅读下面材料,根据其内容和所给段落开头语续写两段,使之构成一篇完整的短文。
When my daughters reached the third and fourth grades, I occasionally allowed them to walk to and from school alone if the weather permitted. One warm spring day, a little dog followed them home after school. It had short legs and long lovely cars, with a fawn-colored coat. It was the cutest dog I had over seen and the girls begged me to keep it.
The dog was barely twelve weeks old. It had no collar or identifying marks of any sort, I didn't know what to do. I thought about running an advertisement in the lost-and-found but I really didn't want to. It would break the kids' hearts if someone should show up. Besides, its owners should have watched it more closely.
By the end of the week the dog was part of our family. It was very intelligent and good with the girls. The following week something told me to check the lost-and-found section in the local paper. One particular advertisement jumped out at me and my heart pounded with fear at what I read. Someone was begging for the return of a lost dog in the neighborhood of our grade school. They sounded desperate. My hand shook. I couldn't bring myself to pick up the phone.
Instead, I pretended I hadn't seen the advertisement. I quickly put paper away in the drawer and continued with my dusting. I never said a word about it to the kids or my husband.
By now we had named the dog. It looked like a Molly, so that was what we called it. It followed the girls everywhere they went. When they went outside, it was one step behind them. .When they did housework, it was there to lend a hand.
There was only one problem with this otherwise perfect picture: my conscience was bothering me. I knew in my heart I had to call that number and see if our Molly was the dog they were desperately seeking. It was the most difficult thing I've ever done.
注意:1.续写词数应为150左右;
2.请按如下格式在答题卡的相应位置作答。
With mixed feelings, I finally picked up the phone.
