21、Scientists at Purdue University created the world’s whitest paint — a discovery that not only adds yet another choice to the“which white should we paint this wall” dilemma, but also might help the climate crisis.
The paint was developed by Purdue mechanical engineering professor Xiulin Ruan and his team. It works through a passive cooling technology that offers great promises to reduce space cooling cost and global warming. “When we started this project seven years ago, we had saving energy and fighting climate change in mind,”Ruan said in a podeast (播客) episode of This Is Purdue. They wanted to create a paint that would reflect sunlight away from a building, dramatically decreasing the need for air conditioning.
Heating, cooling, and lighting account for 28 percent of the world’s total greenhouse gas emissions. And overusing air conditioning can overwhelm a city’s power grid and cause blackouts (停电). In a Queens blackout in 2006,175,000 people were left without power, which lead to 40 deaths. This paint could effectively be an alternative to air conditioners in some places.
The paint reflects 98.1%of solar radiation while also giving out infrared (红外线的) heat. Because the paint takes in less heat from the sun than it gives out, a surface coated with this paint is cooled below the surrounding temperature without using power. Covering a roof area of 1,000 square feet with the paint could create 10 kilowatts ofcooling power, the researchers found.“That’s more powerful than the air conditioners used by most houses,”Ruan told This Is Purdue.
You can’t buy the paint just yet, but researchers are partnering with a company to put the paint on the market. While individual action to fight elimate change can help save our planet, it’s important to note that the vast majority of the world’s greenhouse gas emissions can be traced back to 100companies. Maybe we can douse(浇) those companies with this white paint, too — it could be worth a shot.
【1】What is known about the paint?
A．It has different colors.
B．It doesn’t cost much.
C．It uses heating technology.
D．It is climate-friendly.
【2】What is the Queens blackout mentioned to show?

D．The result of global warming.
【3】Which aspect of the paint is talked about in Paragraph 4?
A．Its application.
B．Its function.
C．Its composition.
D．Its disadvantage.
【4】What can be learned from the last paragraph?
A．The quality of the paint needs improving.
B．The paint will bring profits to the 100 companies.

D．Individual efforts matter in creating the whitest paint.
22、Every year, millions of Americans see their personal information leak into the wrong hands. Maybe there’s spyware on their computer, or a service they use suffered a security reach, leaving customers at risk of exposure. Or perhaps their password is easy to guess: Security company Splash-Data reports that the most popular passwords in 2015 were 123456 and password.
Fear not: It is a lot easier than you might think to set up proper defenses. In fact, you can easily do it all a weekend. Here’s how.
Clean Your Computer And Smart-phone
Before you put new security measures into place, make sure your devices are as spotless as possible. This means installing a good antivirus program and taking the time to clear out any spy-or malware that may have already infected your system. Go with AVG Free Antivirus (free. AVg.com) or Avast! (avast.com) - each is free. Run a full system scan. This can take over an hour, so start it before settling into other plans. When you return to your computer, clear out anything that shouldn’t be there with a few simple steps (the program will guide you). These days, it’s also worth it to make sure your phone is safe from viruses. iPhones are less likely to be targeted by spy-ware, but Android users should download the Lookout app (lookout.com) to scan their devices and ensure everything is as it should be.
Security Your Wi-Fi
Now that your computer is clean, you should plug any holes in your home network. It’s fairly easy for potential criminals to gain access to your information if they’re able to share your connection - that’s why you want to be careful when using public Wi-Fi. For your home, the Federal Communications Commission recommends a few steps. Even though you put security measures into place a couple of years ago, it’s a good idea to refresh your setting. You may have to refer to the instructions for your wireless router or call tech support for help. Different routers will have different setup pages, so the actual step-by-step will vary, but the end result will be the same.
Dig Deep with Your Passwords
Everything you just accomplished could be for nothing if a thief has your existing passwords, so you need to change them for every service you use. Try it when you find yourself on those sites anyway.
What you’ve heard is true: Passwords should use a variety of special characters, numerals, letters, and case when possible. They should be close to random, and there should be a different one for each website you use. Doing this, and keeping track of it all, is a pain - which is why people don’t do it and wind up with stolen identities. Try Dashlane (dashlane.com), a password manager with powerful encryption（加密）that can securely keep track of the most ridiculous codes you can come up with. Best of all, it logs you into sites automatically, so there’s no need to worry about all those obscure keystrokes. Whew!
Never Answer Unwanted Email
Always check the security symbols when using an online site for shopping. If the lock icon encryption is not there, do not give out credit details. Also, check that the site is legal - never go to a site from a random email and start shopping online. Go to the site through a known URL or by searching for it on a search engine first.
Keep a separate credit card just for online shopping. This will make it easier to cancel if something bad does happen and your other credit card for “in real life” can still be used uninfluenced.
Don’t store information on any store’s website. It may be conventional but it’s also a possible loss to you if the site is hacked.
【1】The passage is mainly about ______.
A．ways of avoiding online identity theft
B．tips of freeing computers from viruses
C．measures to ensure network security
D．steps to keep track of passwords
【2】According to the passage, the risk of exposing personal information may possibly be caused by ______.
A．the applications of antivirus programs
B．the practice of using public Wi-Fi
C．the difficult access to the passwords
D．the separate credit card for online shopping
【3】To put new security measures into place, we need to ______.
A．clear out of everything in the system
B．make a random selection of network
C．get rid of potential spy-ware
D．refresh the infected system
23、Home sweet home
No matter how far you've travelled, there's always something special about coming home. It might be your comfortable bed or your mum' s special dish or walking round your local park that makes you feel so happy and comfortable there.
【1】. It's something you learn to deal with better as you grow older; from your first weekend away with school or a youth group, to a week-long holiday with friends, to moving out to university, it becomes ever easier. 【2】 I always long to go home about a week before it's time. It's the expectation of seeing your friends and family, smelling Dad' s apple pie, and feeling your own sheets.

You might not be able to get your favorite foods, but this will force you to try something new. 【4】 , but perhaps it' s more beautiful and sunnier! And although you'll miss friends and family, distance helps you appreciate the truly valuable relationships.
There's a new generation of " children of the world". With more people moving abroad, it's easy to feel like you have many different homes. However, I think this is positive-you lead an enriched life and you learn to value what, where and who really matters to you. 【5】 , you learn to make everywhere your home!
A. And when the world is your shelter
B. Your new town may not be familiar

24、 Connie Monroe clicks a button, turns her wrist and watches as her neighborhood floods. The reed-covered shorelines are first to go. Then, the baseball fields at Fleming Park. By the time seawater reaches the senior center, it has covered streets, flooding more than a dozen complexes that she can see.
Monroe moves her head up and down, side to side, taking in the simulated (模拟的) view. This is what could happen to Turner Station, a historic African American community, as sea levels rise.
“Everything’s underwater. The school is underwater. Our house is underwater,” Monroe says. A frown (皱眉) forms below the virtual reality headset. “Is the water really supposed to get that high?”
Climate change presents many challenges to coastal communities, but one of the most worrisome problems is: how do you show people — and convince them — of a possible future?
“It’s one thing to hear or read the news that sea levels could rise as high as 7 feet in Maryland by the end of the century under worst-case situations, but it’s another to imagine what that will look like in your own backyard,” says Jackie Specht, the coastal science program manager. “And if it’s hard to imagine, it’s hard to face and prioritize.”
Communicating the realness and immediacy of the climate threat is important to climate researchers and those aiming to prevent its causes. But it’s also paramount to communities faced with coming changes that are already unavoidable.
Climate projects need public support and input. That’s why Monroe and other residents at this recent community meeting are being directed to sit in metal chairs, put on virtual reality headsets and watch their homes flood.
Virtual reality is an immersive (沉浸式的) experience that can trick the human brain into thinking it’s real. But tricking people is not the goal of the sea level rise simulation being used at Turner Station, says Juliano Calil, one of the program’s developers.
The goal, he says, “is to help folks visualize the impacts of climate change and the solutions, and also discuss the trade-off between them.”
【1】What would you see in Turner Station as sea levels rise?
A.Shorelines covered by reeds. B.Baseball fields used as parks.
C.Streets blocked with bricks. D.Buildings drowned in water.
【2】What does Jackie Specht suggest in Paragraph 5?
A.People are relatively safer in their backyards.
B.People don’t feel on the scene through the news.
C.The severity of disaster is beyond imagination.
D.The sea level is bound to rise 7 feet in Maryland.
【3】Why is the virtual reality experience provided in the community meeting?
A.To prove climate threat. B.To seek public backing.
C.To help scientific research. D.To introduce VR technology.
【4】Which of the following best explains the underlined words “the trade-off” in the last paragraph?
A.The balance. B.The conflict.
C.The business. D.The similarity.
25、 The term “staycation” means vacations that you take at home or near your home rather than traveling to another place. It is is closely connected with less pollution, saving money and not contributing to the overwhelming disorder that takes place in some of the world's most touristic areas.
