A
Experts say that if food were a country, it would rank second behind theUSas one of the biggest greenhouse gas polluters. The reason is the rising demand for meat. Animal farming is responsible for 14.5 percent of global methane emissions. While cowsare the worst contributors, pigs, sheep, donkeys and other animals play a part as well.
Animal agriculture also causes land to become damaged, water to be polluted and forests to get destroyed. With the world population forecast to rise to 9.8 billion by 2050, things are only looking worse for our already decreasing natural resources. While going vegetarian would help, meat consumption is too deep-rooted in most Western diets to allow for such a sharp, permanent change. That is why experts are advocating substituting some of the beef, chicken, or pork with ordinary insects!
Insects, which grow into adults within a matter of months, if not weeks, are ready for consumption much faster than domestic animals. They also require much less room, use less water and food, and produce far less greenhouse gas than animals.
Of the 1.1 million insect species worldwide, scientists have identified 1,700 as eatable. Among them are ants, grasshoppers, grubs, and earthworms. Just like animals, each insect has a different taste. Tree worms taste just like pork, and grubs are similar to smoked meat.
While eating insects might be a new concept for Western people, over 2 billion people worldwide consume insects as a regular part of their diet. Besides being delicious, insects are high in protein, have very few calories, and are free of the saturated fat found in animal meat. Insects can be prepared in many ways. Creative cooks can use them to cook protein-rich soup, make baked treats, and even fry a few with vegetables. So eat insects--- both your body and Mother Earth will thank you for it!

“We are running out of space and the only places to go to are other worlds... Spreading out may be the only thing that saves us from ourselves. I am convinced that humans need to leave Earth.” These are the words of the famous scientist Stephen Hawking, spoken at a science festival inNorwayin 2017, a year before his death.
Hawking was not alone in this view. Many experts feel that the only way for humanity to last far into the future is to colonize other planets. That way, if an asteroid, a terrible disease, nuclear war, or some other disaster strikes Earth, civilization as we know it would still have a chance. Mars is one of the most tempting destinations. NASA, theUnited Arab Emirates, the private company SpaceX, and the organization Mars One all have plans to send humans there. “Either we spread Earth to other planets, or we risk going extinct, SpaceX founder Elon Musk said at a conference in 2013.
But not everyone agrees that colonizing Mars or any other planet is such a great plan. The most common argument against going is that it’s just too expensive or dangerous. It will take huge amounts of money and other resources just to get people there, let alone set up a place for them to live. It’s not even clear if humans could survive on Mars. One of the biggest dangers there is deadly radiation that bombards the planet.
Maybe all the time and money people would pour into a Mars mission would be better spent on more urgent projects here on Earth, like dealing with poverty or climate change. Some experts argue that handling a problem like an asteroid strike or disease outbreak while staying here on Earth would be much easier and less expensive than surviving on a new planet.
In addition, moving to a new planet could harm or destroy anything that already lives there. Mars seems uninhabited, but it could possibly host microbial life. Human visitors may destroy this life or permanently change or damage the Martian environment. Some feel that’s too much of a risk to take.
What do you think? Should humans colonize outer space or stay home?
4. What can be inferred from the passage?
A. Many experts insist that humans should take the risk.
B. Mars is the most attractive destinations for human beings.
C. Hawking firmly believes the only way to save humans is moving to Mars.
D. All the other experts don’t agree with Hawking’s idea.
5. Why do some experts disagree with the plan to colonize Mars?
A. It will cost much more money to settle on Mars than on Earth.
B. It is too long a distance from the Earth to the Mars.
C. Human visitors will bring diseases to Martian environment.
D. The deadly radiation that bombards the planet is the biggest danger.
6. What’s the writing purpose of the passage?
A. To raise people’s awareness of protecting the environment.
B. To present different opinions on whether to move to the Mars.
C. To arouse readers’ reflection on whether to colonize outer space.
D. To inspire people to deal with the environmental problems.
7. In which section of a magazine is the passage most likely from?
A. Fiction.
B. Current affairs.
C. Social Studies.
D. Science.
C
This year researchers expect the world to snap 1.35 trillion photographs, or about 3.7 billion per day. All those pixels (像素) take up a lot of room if they are stored on personal computers or s phones, which is one reason why many people store their images in the cloud. But unlike a hard on drive which can be encrypted to protect its data, cloud storage users have to trust that a tech platform will keep their private pictures safe. Now a team of Columbia University computer scientists has developed a tool to encrypt (加密) images stored on many popular cloud services while allowing authorized users to browse and display their photographs as usual.
Malicious (恶意的) attempts to access or leak cloud-based photographs can expose personal information. In November 2019, for example, a bug in the popular photograph storage app Google Photos mistakenly shared some users' private videos with strangers. Security experts also worry about employees at cloud storage companies on purpose accessing users' images.
So the Columbia researchers came up with a system called Easy Secure Photos (ESP), which they presented at a recent conference. “We wanted to see if we could make it possible to encrypt data while using existing services,” says computer scientist Jason Nieh, one of the developers of ESP. “Everyone wants to stay with Google Photos and not have to register on a new encrypted-image cloud storage service.”
To overcome this problem, they created a tool that preserves blocks of pixels but moves them around to
effectively hide the photograph. First, ESP's algorithm (算法) divides a photograph into three separate files, each one containing the image's red, green or blue color1 data. Then the system hides the pixel blocks around among these three files (allowing a block from the red file, for instance, to hide out in the green or blue ones). But the program does nothing within the pixel blocks, where all the image processing happens. As a result, the files remain unchanged images but end up looking like grainy black-and-white ones to anyone who accesses them without the decryption (解密) key.
8. What's probably the main purpose for people to store images in the cloud?
A. To save storage room.
B. To make photos beautiful.
C. To try a new storage way.
D. To keep their privacy safe.
9. Why might employees in cloud storage companies be distrusted by experts?
A. They sell users' passwords.
B. They have invented new tools.
C. They often let out personal information.
D. They may steal a glance at users' images.
10. What's the advantage of ESP?
A. It can provide clear images.
B. It can decrease the upload time.
C. It can classify images automatically.
D. It can encrypt data on the original platform.
11. What does paragraph 4 mainly talk about?
A. Method of decryption.
B. Image-processing technique.
C. Separate files of images.
D. Data analysisof color1 s.
D
Yu Chenrui, 29, is a maker of automata (机关人偶) in Chengdu, Sichuan province. Automata are built to look like humans or animals and give the illusion (错觉) of being able to move ontheir own, “The art form amazes me, because it combines various skills, from storytelling to mechanics, and the pieces are built with a sense of humor,” Yu says. His creations have caught the attention of well-known artists and his fancy pieces of art have attracted collectors worldwide.
Interested in handcrafts as a boy, Yu first encountered automata designed by Japanese artist Kazuaki at an exhibition in 2015 when he studied at the Communication University of China in Beijing. “It was like meeting a
like-minded friend, ” Yu says, recalling the moment. As an art and design major, he began to learn the craft by himself and, with the support of his tutor, he kept studying and examining automata in school.
When he graduated in 2016, Yu landed a job at an advertising agency in Beijing. He stayed on at the company for three years because, at that time, he was not sure that he could make a living out of his hobby. While working as a designer Yu kept exploring and advancing his skills in wood carving and mechanics. Eventually, despite the job’s good salary, it was not enough to make up for not following his true passion. Finally, in 2018, Yu quit his job and returned to Chengdu to open his automata workshop.
To keep himself occupied while running his workshop, he planted blueberries, raspberries and cherries. He watered, weeded and added fertilizer (肥料) every day. “Daily routines helped me calm down and inspire my creativity, which resulted in an automaton called To Observe the Autumn,” Yu says.
Over time, Yu’s reputation grew and his business flourished (兴旺). Many of Yu’s creations are built with a dash of wisdom, a sprinkle of humor and are inspired by observations of real life. Yu knows that there are many more creative ideas waiting to be expressed. “It feels quite good to be fully devoted to automata creation and I am still searching for myself.”
12. What can we learn from the first paragraph?
A. Yu is equipped with various skills.
B. Yu is a person full of sense of humor.
C Yu is now gaining recognition worldwide.
D. Yu is following the latest trend in handcraft.
13. Why did Yu quit his job in Beijing?
A. He couldn't make a living out of it.
B. He wanted to pursue his own dream.
C. He missed his family in Chengdu.
D. He thought he had a lot experience.
14. According to Yu, what contributes to his creativity as an automata artist?
A. The fruits he grows.
B. Success of his business.
C. His devotion to the job.
D. Observation from daily life.
15. Which of the following can best describe Yu’s story?
A. There is no end to learning.
B. Great hopes make great man.
C. Actions speak louder than words.
D. Experience is the mother of wisdom.
