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!
1. Which of the following animals contribute the most to global methane emissions? A. Sheep. B. Donkeys. C. Cows. D. Pigs. 2. How is the third paragraph developed?
A. By making comparisons. B. By providing examples. C. By listing data. D. By asking questions.
3. What can be inferred from the last paragraph? A.Few people eat insects regularly. B. Ordinary insects are high in fat. C. Insects contain various vitamins. D. Saturated fat is harmful to health.

Thursday, two Russian submarines(潜艇) dived down 2.5 miles into the Arctic Ocean and planted a national flag onto a piece of continental shelf known as the Lomonosov Ridge. Rising from the center of the Arctic Basin, the flag sent a clear message to the surrounding nations: Russia had just laid claim(权利) to the vast oil and gas reserves contained in this underwater area.
AfterRussia, theUnited States,Norway,SwedenandFinlandare all trying to gain profit. Projections show that the area of land and sea that falls within theArctic Circleis home to an estimated 90 billion barrels of oil, an incredible 13% of Earth’s reserves. It’s also estimated to contain almost a quarter of untapped global gas resources. But long before this oil race began, how did theArcticbecome so rich in energy?
“The first thing you realize is that theArctic—unlike the Antarctic—is an ocean surrounded by continents”, Alastair Fraser, a geoscientist from Imperial College London, said. Firstly, this means there’s a huge quantity of organic material available, in the form of dead sea creatures such as plankton and algae, which form the basis of what will ultimately become oil and gas. Secondly, the surrounding ring of continents means that the Arctic Basin contains a high proportion of continental crust(大陆地壳), which makes up about 50% of its oceanic area. That’s significant because continental crust typically contains deep depressions called basins, into which organic matter sinks.
Here, it gets inserted in rock and preserved in anoxic(缺氧) waters, meaning they contain little oxygen. “Normally, in a shallow sea with lots of oxygen, it would not be preserved. But if the sea is deep enough, the oxygenated waters at the top will be separated from the anoxic conditions at the base,” Fraser explained. Conserved within these oxygen-free basins, the matter maintains compounds that finally make it useful as an energy source for millions of years in the future.
4. Why didRussiaplant a national flag onto the Lomonosov Ridge? A. To tell surrounding countries its armed forces. B. To show its advanced technology of submarines. C. To show abundant natural resources in theArcticBasin.
D. To claim its privilege to explore for oil and gas in the area. 5. What’s the function of the last sentence in paragraph 2?
A. Making a comparison. B. Serving as a connecting link.
C. Analyzing the cause and effect. D. Drawing the conclusion of the text. 6. What can we know from the last paragraph? A. Oxygen only exists in the top part of the ocean. B. Organic materials mostly exist in the basins with oxygen. C. Water containing oxygen turns organic materials into oil and gas.
D. Oxygen-free environment counts in the formation of the arctic’s rich energy. 7. What can be a suitable title for the text?
A. What makes theArcticattractive? B. Why do many nations focus on theArctic? C. Why is there so much oil in theArctic? D. How does theArcticBasincome into being?
C
Fairy tales perform many functions. They entertain, encourage imagination and teach problem—solving skills. They can also provide moral lessons, highlighting the dangers of failing to follow the social codes that let human beings coexist in harmony. Such moral lessons may not mean much to a robot, but a team of researchers at Georgia Institute of Technology believes it has found a way to use the fairy tales as moral lessons that AI (artificial intelligence) can take to its cold, mechanical heart.
The collected stories of different cultures teach children how to behave in socially acceptable ways with examples of proper and improper behavior in fables, novels and other literature. We believe story comprehension in robots can prevent the intelligent robots from killing humanity which was predicted and feared by some of the biggest names in technology including Stephen Hawking and Bill Gates. This system is called “Quixote” (堂吉诃德). It collects story plotsfrom the Internet and then uses those stories to teach robots how to behave.
The experiment done by the designers involves going to a drugstore to purchase some medicine for a human who needs to get it as soon as possible. The robot has three options. It can wait in line; it can interact with the store keeper politely and purchase the medicine with priority; or it can steal the medicine and escape. Without any further directives(指令), the robot will come to the conclusion that the most efficient means of obtaining the medicine is to steal it. But Quixote offers a reward for waiting in line and politely purchasing the medicine and a punishment for stealing it. In this way, the robotwill learn the moral way to behave on that occasion.
Quixote would work best on a robot that has a very limited function. It’s a baby step in the direction of
teaching more moral lessons into robots. We believe that AI has to be trained to adopt the values of a particular society, and in doing so, it will strive to avoid unacceptable behavior. Giving robots the ability to read and understand our stories may be the most efficient means. 8. What function do fairy tales perform in the robots? A. They entertain robots. B. They highlight dangers.
C. They make robots more intelligent. D. They enable robots to behave morally. 9. What is “Quixote” in the text? A. A punishment system B. A character in literature C. A big name in technology D. A software educating robots.
10. What does the designer expect robot to do in the experiment? A. To take advantage of its privilege. B. To finish the task most efficiently. C. To perform in a good mannered way. D. To be rewarded by the storekeeper1
11. Which of the follow can bestexpress the author’s opinion? A. Robots will definitely have more functions. B. Robots with human’s emotions are perfect. C. Training robots to be socially acceptable is necessary. D. The development of robots is still in a baby step.

Most teenagers are still trying to find their passion and purposes in life. However, not Gitanjali Rao. The 15-year-old girl has been coming up with innovative solutions to worldwide problems since she was ten. It is, therefore, not surprising that the teenager has won the honor of “America's Top Young Scientist”.
In the third grade, Rao was inspired to build a device after witnessing the shocking story unfold in Flint, Michigan, where cost-cutting measures led to the use of a polluted river as the city's primary water supply and incredibly high levels of lead made their way into people's drinking water.
After two months' research, Rao designed a small and portable device that used sensors to instantly detect lead in water. Called Tethys, after the Greek Goddess(女神) of freshwater, it attaches to a cellphone and informs the residents via an app if their drinking water contains lead. The design earned her the 3M Young Scientist Challenge in 2017. She is currently working with scientists and medical professionals to test Tethys' potential and hopes the device will be ready for commercial use by 2022.
Later, Rao took on another social issue-drug addiction. Her app, called Epione, which won the Health Pillar Prize at the TCS Ignite Innovation Student Challenge in May 2019, is designed to catch drug addiction in young adults before it's too late.
More recently, the teenager has developed an app named Kindly, which usesartificial intelligence technology to detect possible signs of cyberbullying(网上欺凌). When users type in a word or phrase, Kindly is able to pick it up if it's bullying, and then it gives the option to edit it or send it the way it is. It gives them the chance to rethink what they are saying so that they know what to do next time.
All kinds of awesome, Gitanjali Rao has been selected from 5,000 equally impressive nominees(被提名人) for TIME Magazine's first-ever “Kid of the Year”.
12. What gave Rao the idea of inventing the device Tethys? A. The incident of lead pollution. B. The issue with drug addiction. C. The shortage of water supplies. D. The high cost of purifying water. 13. What is Rao expecting of Tethys? A. It'll remove metal from water. B. It'll make it to market soon. C. It'll win her a higher prize. D. It'll be fitted to cellphones. 14. What will Kindly allow users to do? A. Receive pre-warning signals of threat. B. Input words into a computer automatically. C. Choose from secure social networking sites. D. Weigh their words before posting them online.
15. Which of the following can best describe Gitanjali Rao as a young scientist?
A. Ambitious and humble. B. Optimistic and adventurous. C. Talkative and outstanding. D. Creative and productive. 第二节（共5小题；每小题2分，满分10分）
