1 . On Friday, Japanese researchers announced a population clock that showed a dangerous situation that the Japanese nation would disappear in 1,000 years if the falling birth rate kept the present level. Researchers in the northern city of Sendai said that Japan’s population of children aged up to 14, which now stands at 16.6 million, was falling at the rate of one child per 100 seconds. It would lead to a terrible result that there would be no children left in Japan in 1,000 years.
“If the rate keeps falling at that rate in our country, there will only be one child who is able to enjoy the following Children’s Day left on May 5th,3011,” said Hiroshi Yoshida, a professor at Toholu University. “But 100 seconds later, a national disaster that there are no children left in Japan will happen,” he added, “The nation’s people will disappear for the birth rate has fallen to the level that every woman has no more than two children, which started in 1975.” Yoshida said they created the population clock to make Japanese people pay close attention to that problem for their nation’s future.
Another study showed that Japan’s population was expected to fall to one third of the present population amount: 127.7 million in the next century. The Japanese government predicted that the birth rate would just become 1.35 children per parents within 50 years.
At the same time, Japanese life expectancy which is expected to ascend from 86.93 years in 2010 to 90.93 years in 2060 for women and from 79.64 years to 84.19 years for men has already been one of the highest in the world. More than 20 percent of the Japanese are aged 65 or over.
It means that Japan has become one of the countries with aging populations in the world. The problem of aging populations is a headache for the government and the Japanese economy because there are fewer and fewer workers who can make money for the country. However, the government has to face the terrible situation that it needs to offer a growing number of pensions.

2 . This past July was the hottest recorded month in human history. Heat waves brake temperature records worldwide. It’s more than just a matter of sweaty discomfort. As climate change worsens, access to artificially cooled spaces is rapidly becoming a health necessity.
Yet standard air-conditioning systems leave us trapped in a negative feedback cycle: the hotter it is, the more people use the air condition er and the more energy is consumed as a result. Cooling is the fastest-growing single source of energy use in buildings, according to the International Energy Agency. Breaking the cycle requires new innovations that will help bring cooler air to more people with less environmental impact.
Standard air-conditioning systems cool and dehumidify (除湿) through a relatively inefficient mechanism: in order to condense (冷凝) water out of the air, they overcool that air past the point of comfort. Many new designs therefore separate the dehumidification and cooling processes, which avoids the need to overcool. For example, some new air conditioner designs pull water from the air with desiccant (干燥剂) materials. The dried air can then be cooled to a more reasonable temperature. Massachusetts-based start-up Transaera claims that the system it is developing could use 35 percent less energy than the average standard air-conditioning unit.
However, the gains in efficiency might not help us get rid of the impact of air-conditioning. “It won’t work to simply replace every existing air conditioner with a better model and call it a day,” says Nicole Miranda, an engineer at the University of Oxford. “Instead, a truly coder future will have to employ other strategies. It’s critical to bring greenery and water bodies into cities to take advantage of natural airflow.”
“Cooling is a challenge involving many aspects,” says Sneha Sachar, an expert at the nonprofit organization ClimateWorks. “There isn’t one strategy or one answer. We need a combination of better buildings and cities, better technologies and a better understanding that the true cost of air-conditioning extends beyond electric bills.”

3 . The Hadza hunter-gatherers of Tanzania live a life that has not changed much over ten thousand years. They have no crops, no house animals, no permanent shelters. In spite of long exposure to agriculturalist groups around them, the Hadza have maintained their lifestyle.
The story of the spread of agriculture is the story of growing population density (密度). Villages formed, then cities, then nations. Agriculture’s rise, however, came with a price. It introduced infectious diseases, social inequality, occasional famines (饥荒) and war. Professor Jared Diamond of UCLA (University of California, Los Angeles) has called the adoption of agriculture “the worst mistake in human history”— a mistake from which we have never recovered.
Looking at the Hadza, you can see why he came to this conclusion. They do not engage in warfare. They do not live densely (稠密地) enough to be threatened by an infectious outbreak. They have no known history of famine (饥荒). The Hadza diet is more stable (稳定 的) and varied than that of most of the world’s citizens. They live almost entirely free of possessions. They enjoy an extraordinary amount of leisure time, “working” — actively pursuing food — only four to six hours a day.
The chief reason the Hadza have been able to maintain their lifestyle so long is that their homeland is not an inviting place. Recently, however, population growth has brought a flood of people into Hadza lands. The region has generally been viewed by outsiders as unused, a Place in need of development. The Hadza, who by nature are not a combative (好战的) people, have almost always moved away instead of fighting.
There are many things to envy about the Hadza, mostly what free spirits they appear to be. Free from schedules, jobs, bosses, bills, traffic, taxes, laws, social duties and money. But who of us could live like them? It’s incredibly risky. Medical help is far away. One bad fall from a tree, one bite from a snake, and you’re dead. The fact is that it’s too late for us to go back to the Hadza lifestyle. Of greater concern is that soon it may be impossible for them to maintain theirs.

| C．The formation of village. | D．The appearance of a city. |
| A．They are always busy in all seasons |

4 . When given the choice, about 85% of people say they would not want to know about some negative event far in the future. Yet recently millions around the globe have downloaded FaceApp, which allows users to see how they might age in real life.
Many had fun with joking that they love the FaceApp old filter (滤镜). Beneath the humor is a serious subject: How do we learn to relate to our future selves? It’s important that we try to because it could help strengthen the long-term decisions that we make. However, we often fail to make sacrifices for the older versions of ourselves.
More than half of the respondents in a recent survey of 2, 800 Americans said they rarely or never thought about what their lives might be like 30 years from now. This isn’t surprising, since most of us are firmly rooted in the present and thinking about the distant future can seem like a distant priority. My ongoing research might also offer an explanation: We tend to think about our future selves as if they are someone different from who we are today. In an effort to narrow these empathy (共情) gaps, my research workmates and I have tried to humanize (使人性化) people’s future selves in the same way others have tried to humanize charity receivers. Given that a photograph of one hungry child can spark emotional reactions, and cause viewers to donate, we have provided participants with vivid images of their distant selves.
That seems helpful. In a recently completed project in Mexico, we found that exposure to future-self images led more people to add to their pensions (养老金). Despite this research, I’m not sure that the app users will suddenly increase their pension and care about their health. The silly app isn’t paired with an immediate opportunity to change any of these things.
The lesson from FaceApp shouldn’t be that we need to combine hi-tech visuals with savings for retirement. The lesson, then, leads to a question: What more can be done to urge us to think about, care for who we will one day become?
1. What can we learn about FaceApp?| A．It provides future-self images. | B．It is the most downloaded app. |

| D．They consider future selves the same as today’s. |
| A．Completing a project in Mexico. |
| B．Offering aging images of participants. |
| C．Raising reflections among viewers. |
| D．Giving a photograph of a hungry child. |
| A．Positive. | B．Objective. |
| C．indifferent. | D．Unfavorable. |
5 . Do you like to bury your head in a good book? Getting absorbed in a good story is a great way to relax. It improves your literacy, and, according to some experts, it’s good for your health as well.
For the purist, the only way to digest a good story is with a paperback or hardback book. Being in print, it’s possible to feel and even smell the book. And of course it’s very portable.
The e-book has become popular in schools, too, and according to one school in London, it’s encouraged more children to read.
The recent lockdowns due to the coronavirus pandemic have certainly given us all time to read more, and in the UK at least, sales of physical books have risen strongly.
| A．Last year, some 202 million paperbacks and hardbacks were sold. |
| B．Reading books does not rate highly among Britons as a leisure activity. |
| C．For adults, e-books are certainly a lightweight way of accessing our favourite literature on the move. |
| D．But for those who can’t or don’t want to look at the text in a book, there are audiobooks to listen to. |
| E．Research has shown that readers remember more information reading from paper books than e books. |
| F．But the traditional book has had a rival (竞争对手) in recent years from e books, which are read on e-readers or tablets. |
| G．Studies show that it can increase our emotional intelligence as we understand a range of perspectives and motivations. |
6 . By March 2018, Cape Town’s biggest reservoir (储水库) had dropped to just 11 percent of its capacity. The city was close to turning off the taps. “I’ve never experienced anything like it,” said Samantha Reinders. Like everyone else here, Reinders learned to wash, cook and drink using just the official daily limit—50 liters. Posters were put up everywhere, telling 400,000 people in Cape Town how far the reservoirs had dropped. They also showed the countdown until “Day Zero”. Finally, in June, the rains returned. People ran outside to feel the water flow on their faces. Cape Town’s water shortage was over, at least temporarily. “Day Zero” had never quite arrived.
Afterward, an international group of scientists analyzed Cape Town’s drought and water shortage. They studied computer models and rainfall records. Finally, they came to a conclusion: Climate change wasn’t the culprit (罪魁祸首) of the drought. It hadn’t begotten the drought. But it had tripled (使成三倍) the chance that a drought would occur.
Friederike Otto is a climate scientist at Oxford University in England and lead author of that study. The risk of drought could triple again by the end of the 21st century, she said. That’s when global temperatures are predicted to rise another 1 degree Celsius.
Co-author Piotr Wolski said that better planning could help in the future. The area could manage its water reservoirs more carefully. People could fix leaky dams and make use of a variety of water sources instead of only reservoirs. “Drought may or may not translate into a crisis (危机),” he pointed out.
In many ways, said Reinders, the water crisis made a change to the city. Most people, across race, gender, religion and class, did their best to save water and help their neighbors out. And most were sticking to the water-saving habits they had learned. “I think this is the new normal. And that is pretty much the word on the street,” said Reinders.
1. What does Paragraph 1 show about Cape Town?| A．It experienced a severe drought. |
| B．It was carrying out a water-saving campaign. |
| C．It needed one more reservoir urgently. |
| D．It was repairing its water-supply lines. |
| A．Caused | B．Stopped | C．Expanded | D．Worsened |
| A．Never too late to mend. | B．Be aware of the potential leaky dams. |
| C．Save for a rainy day. | D．Make full use of the water reservoirs. |
| A．To call on people to show kindness to others. |
| B．To stress people’s efforts to save water. |
| C．To encourage people to stick to their good habits. |
| D．To show the beneficial sides of the water crisis. |

8 . As data and identity theft becomes more and more common, the market is growing for biometric(生物测量) technologies—like fingerprint scans—to keep others out of private e-spaces. At present, these technologies are still expensive, though.
Researchers from Georgia Tech say that they have come up with a low-cost device(装置) that gets around this problem: a smart keyboard. This smart keyboard precisely measures the cadence(节奏) with which one types and the pressure fingers apply to each key. The keyboard could offer a strong layer of security by analyzing things like the force of a user’s typing and the time between key presses. These patterns are unique to each person. Thus, the keyboard can determine people’s identities, and by extension, whether they should be given access to the computer it’s connected to—regardless of whether someone gets the password right.
It also doesn’t require a new type of technology that people aren’t already familiar with. Everybody uses a keyboard and everybody types differently.
In a study describing the technology, the researchers had 100 volunteers type the word “touch” four times using the smart keyboard. Data collected from the device could be used to recognize different participants based on how they typed, with very low error rates. The researchers say that the keyboard should be pretty straightforward to commercialize and is mostly made of inexpensive, plastic-like parts. The team hopes to make it to market in the near future.
1. Why do the researchers develop the smart keyboard?| A．To reduce pressure on keys. | B．To improve accuracy in typing. |
| C．To replace the password system. | D．To cut the cost of e-space protection. |
| A．Computers are much easier to operate. |
| B．Fingerprint scanning techniques develop fast. |
| C．Typing patterns vary from person to person. |
| D．Data security measures are guaranteed. |
| A．It’ll be environment-friendly. | B．It’ll reach consumers soon. |
| C．It’ll be made of plastics. | D．It’ll help speed up typing. |
| A．A diary. | B．A guidebook | C．A novel. | D．A magazine. |
9 . Sometimes you'll hear people say that you can't love others until you love yourself. Sometimes you'll hear people say that you can't expect someone else to love you until you love yourself. Either way, you've got to love yourself first and this can be tricky.
Sure we all know that we're the apple of our parents' eyes, and that our Grandmas think we're great talents and our Uncle Roberts thinks we will go to the Olympics, but sometimes it's a lot harder to think such nice thoughts about ourselves. If you find that believing in yourself is a challenge, it is time you build a positive self-image and learn to love yourself.
Self-image is your own mind's picture of yourself. This image includes the way you look, the way you act, the way you talk and the way you think. Interestingly, our self-images are often quite different from the images others hold about us. Unfortunately, most of these images are more negative than they should be. Thus changing the way you think about yourself is the key to changing your self-image and your whole world.
The best way to defeat a passive self-image is to step back and decide to stress your successes. That is, make a list if you need to, but write down all of the great things you do every day. Don't allow doubts to occur in it. It very well might be that you are experiencing a negative self-image because you can't move past one flaw or weakness that you see about yourself. Well, roll up your sleeves and make a change of it as your primary task. If you think you're silly because you aren't good at math, find a tutor. If you think you're weak because you can't run a mile, get to the track and practice. If you think you're dull because you don't wear the latest trends, buy a few new clothes. But remember, just because you think it doesn't mean it's true.
The best way to get rid of a negative self-image is to realize that your image is far from objective, and to actively convince yourself of your positive qualities. Changing the way you think and working on those you need to improve will go a long way towards promoting a positive self-image. When you can pat yourself on the back, you'll know you're well on your way. Good luck!
