This passage connected Europe in the West with China in the East, and allowed the exchange of goods, technology, and ideas between the two civilizations. Although merchants could make huge profits travelling the road, it was not without risk.Travelers commencing their journey from this city could take a northern route that would taked face the Gobi Desert, arguably the greatest danger of the Silk Road.The Gobi Desert, the largest desert in Asia, consists mainly of rocky, hard earth. This feature made it easier for traders to travel across, compared to sandy deserts like the neighboring Taklamakan Desert. Like other deserts, the Gobi Desert is dry and hot, and therefore the biggest challenge travelers faced was obtaining enough water for themselves as well as for their camels.So, rest stops were created along the route, allowing travelers to rest, eat and drink. These places also promoted the exchange of goods, and even ideas, amongst the travelers who stoppedtravelers could avoid spending too much time in the desert, which would make them targets for robbers, another danger of the Silk Road.Once through the Gobi Desert, travelers would continue their journey into Iran, Turkey, and finally Europe. Whilst this part of the journey may have been less dangerous, it is not entirely without its perils.28_.A. making huge profitsB. traveling the Silk RoadC. exchanging goods and ideasD. connecting different civilizations29.

What is the passage mainly about?A. The origins of the Silk Road.B. The benefits of the Silk Road.C. The difficulties faced by Silk Road travelers.D. The cultural exchanges among Silk Road travelers.D: King Hiero contracts the ancient Greek polymath Archimedes ( ) to detect fraud in the manufacture of a golden crown.

Archimedes accepts the challenge and, during a subsequent trip to the public baths, realizes that the more his body sinks into the water, the more water is displaced—making the displaced water an exact measure of his volume. Realizing he has hit upon a method to determine whether the King’s crown was made of gold or silver, the young Greek leaps out of the bath and rushes home naked crying “Eureka! Eureka!” Or, transla ted: “I’ve found it! I’ve found it!”Too bad, however, Archimedes probably never uttered the phrase in that way.First and foremost, Archimedes himself never wrote about this episode, although he spent plenty of time detailing the laws of buoyancy (浮力). The oldest authority for the naked-Archimedes eureka story is Vitruvius, a Roman writer, who included the tale in his introduction to his ninth book of architecture. “Vitruvius may have gotten it wrong,” says Chris Schmitt, a mathematician at the University of Berlin and a self-described Archimedes fan. “The method attributed to Archimedes in the story works in theory so it sounds right, but when you actually try it, you find that the real world gets in the way.”In fact, Schmitt is one of a long line of scientists, including Galileo, who have read the account and thought, “That can’t be right.” As Galileo wrote, Archimedes could have achieved a far more precise result using his own law of buoyancy and an accurate scale. In fact, the surface tensi on of water can make the volume of a light object like a crown immeasurable. “There may be some truth to it,” Schmitt adds. “Archimedes did measure the volume of things but the eureka moment was maybe due to his original discovery concerning buoyance, not to sitting in the bathtub and then running through the streets naked.”Much like Newton’s apple, the exclamation persists because of the enduring power of the story: a golden crown, a life in the balance, a naked mathematician. The suspect foundations of the eureka moment take nothing away from the word’s ability to uniquely and concisely convey the flash of inspiration.32. According to the first paragraph, how would Archimedes measure the volume of the crown?A. He would weigh himself with and without the crown.B. He would weigh the crown first and then put it into water.C. He would go to the public baths wearing the crown on his head.D. He would sink the crown into water and measure the water displaced.33. What did Galileo probably think of the naked-Archimedes eureka story?A. He believed the word “eureka” was said in another situation.B. He suspected Archimedes didn’t run through the street naked.C. He doubted Archimedes carried out the experiment independently.D. He thought Archimedes would not have used the method described.34. What can be inferred from the underlined sentence in the last paragraph?A. The word “eureka” is still widely used today.B. The word “eureka” is now a formal scientific term.C. Most people accept the authenticity of the original story.D. People are still inspired by the achievements of Archimedes.35. What is the purpose of this text?A.

Haley set up a station at a table with the dress and some color1 ed markers so that her students could draw on it, having first seen the idea on Pinterest.After the kids had finished the design, she then surprised them all by wearing the dress to class, sharing pictures of herself in it on Facebook in a post that has since been shared over 200, 000 times.For teachers looking to do something similar for their own students, Haley said that she bought the dress off Amazon for less than $ 20 about six months ago and pre-washed the dress before she started the project. She used markers from Walmart. But she said these things can be bought in other places. She said, “To do the project, I set up a station at a table with the dress and markers. It takes anywhere from two weeks to a month to complete as we just work on it here and there when time allows. You'd better give the students enough time so they don't have to hurry.”“Teachers have been sharing their dresses, T-shirts, etc. with me that they've been creating since the 1950s with the same idea. It is amazing, and I love the fact that you are sharing them with me! Thank you all so much for your kindness and support,” she wrote on Facebook.Asked why she came up with the idea, Haley told Scary Mommy. “We don't have art in our school, so, I always try to do little creative projects when possible.”4.

To exciteher students' creativity.CExperts are warning about the risks of extremely picky(挑剔的)eating after a teenager living on a diet of chips and crisps developed lasting sight loss. Eye doctors inBristolcared for the 17-year-old after his sight had gone to the point of blindness. Tests showed he had serious vitamin deficiency(缺乏). Dr. Denize Atan, who treated him at the hospital, said, “His diet was basically a portion of chips from the local fish and chip shop every day. He also used to snack on crisps and sometimes white bread and ham, and not really any fruit and vegetables.”The teenager saw his doctor at the age of 14 because he had been feeling tired and unwell. At that time he suffered from vitamin B12 deficiency, but he did not stick with the treatment or improve his poor diet. Three years later, he was taken to theBristolEyeHospitalbecause of progressive sight loss.He was not overweight or underweight, but he had lost minerals from his bones, which was really quite shocking for a boy of his age. In terms of his sight loss, he met the standards of being blind. “He had blind spots right in the middle of his sight,” said Dr Denize Atan, “That means he can’t drive and would find it reallyarduousto read, watch TV or recognize faces.”Dr Denize Atan said that parents should learn about the harm that can be caused by picky eating, and turn to experts for help. For those who are concerned , she advised, “It’s best not to be anxious about picky eating , and instead calmly introduce one or two new foods with every meal.” She said multivitamin tablets can supplement(补充) a diet, but cannot take the place of eating healthily. “It’s much better to take in vitamins through a varied and balanced diet,” she said, adding that too manycertain vitamins , including vitamin A, can be harmful ,“so you don’t want to overdo it.”8. What does Dr Denize Atan imply in paragraph 1?A. The diet of the boy is not balanced.B. Fruit and vegetables are rich in vitamins.C. Picky eating is common among teenagers.D. The cause of the boy’s disease is unknown.9. Why did the boy go to see his doctor at the age of 14?A. To improve his poor diet.B. To get some help to lose weight.C. To be treated for his discomfort.D. To slow down his progressive sight loss.10. What does the underlined word “arduous” in paragraph 3 probably mean?A. Important.B. Easy.C. Necessary.D. Difficult.11. What does the last paragraph mainly talk about?A. Reasons why the boy is seriously ill.B.Suggestions for the boy’s family to care for him.C. Advice for parents worried about picky eating.D. Waysof taking in enough vitamins and minerals.DOver the years, NASA has successfully sent several rovers (飞行器) to Mars. While the science laboratories continue to provide important information on the Red Planet, they keep the space exploration rovers staying closeto the original landing place.To get a more comprehensive (详尽的) view of Mars, the US Space Agency plans to make a small test helicopter with the Mars 2020 Rover, which will be sent off in July 2020.The football-sized “marscopter” weighs about four pounds.It can fly at about ten times the speed of helicopters on Earth. The light weight and fast speed are important for the helicopter to be able to fly in the thin Mars atmosphere, which is about just one percent of that of Earth. “To make it fly in that thin Mars atmosphere, we had to make everything ready, and make it as light as possible while being as strong and powerful as it can possibly be. “Mimi Aung, Mars helicopter project manager, said in a meeting.Upon landing on the Red Planet, the Mars 2020 Rover will find a proper location to send of the helicopter. The helicopter will start with a short climb, no higher than 10 feet, and hover (盘旋) for just 30 seconds before landing back on the Mars surface. If all goes well, five more flights of longer distances, for 90 seconds each, will be conducted over the next 30 days. The short journeys will be recorded by a small camera and sent back to the scientists on Earth.If the plan goes on well, the first helicopter to fly in another world, will open up a whole new way to explore Mars.

AMama and I spend mornings cleaning up the dirt that blows into our house. Mama says all the dust is due to the drought. The dirt sifts into everything. It covers our clothes. We have to wash the dishes before each meal. We rarely drive the truck because Papa fears the dust from the road will ruin the motor.When my sister, Faye, and I walk to school, we wear kerchiefs over our mouths so we don’t breathe in the dirt. On days when the air is so bad that they close the school, we stay home and help Mama put wet sheets over the windows. But the dirt always finds a way in.Last Sunday, there was no dirt in the air, only bright spring sunshine and a clear blue sky. After lunch, Papa headed out to the field to check on the cattle while I played with Faye in the yard. The temperature suddenly dropped. I looked to the west and saw a huge black cloud of dust. All the birds flew away. “I must warn Papa,” I thought to myself. To avoid her panicking, I gently told Faye to go back inside where she would be safe, and then headed off to the field.The storm hit so fast, and in an instant the day turned into night. By the time I entered the cow field the fine sand was whipping across my face. I screamed for Papa, hoping my voice would lead him back.The dirt and sand stung my skin like a thousand bees. Although I was terrified, I refused to turn back. My dad was stranded and needed my help. Covering my face with one hand, I groped my way toward the truck and opened the door. First I tried turning the truck’s lights on and off, hoping that Papa would see them flashing, but the sandstorm let no light escape. Then I pushed the horn again and again, so Papa would hear it. I pushed until I had no more strength in my arms.Suddenly, Papa’s face appeared at the window. My heart leaped with surprise and relief. He opened the door and climbed onto the seat next to me. He then pulled me into his arms and said, “Oh, Iris, you saved me!”Finally, the wind subsided and the dust began to settle. Dirt was piled up to the window on one side of the truck and halfway up the door on the other. Papa kicked against the door, opening it far enough to let us out.Sand and soil drifts were everywhere, but we were safe.21. What is the main function of the first two paragraphs?A.

This passage connected Europe in the West with China in the East, and allowed the exchange of goods, technology, and ideas between the two civilizations. Although merchants could make huge profits travelling the road, it was not without risk.The main Silk Road started in Chang’an (known today as Xi’an), the early Han capital. Travelers commencing their journey from this city could take a northern route that would take them across China’s northwestern provinces. After this, they woul d face the Gobi Desert, arguably the greatest danger of the Silk Road.The Gobi Desert, the largest desert in Asia, consists mainly of rocky, hard earth. This feature made it easier for traders to travel across, compared to sandy deserts like the neighboring Taklamakan Desert. Like other deserts, the Gobi Desert is dry and hot, and therefore the biggest challenge travelers faced was obtaining enough water for themselves as well as for their camels.So, rest stops were created along the route, allowing travelers to rest, eat and drink. These places also promoted the exchange of goods, and even ideas, amongst the travelers who stopped there. Usually, the rest stops were placed within a day’s journey of each other. In this way, travelers could avoid spending too much time in the desert, which would make them targets for robbers, another danger of the Silk Road.Once through the Gobi Desert, travelers would continue their journey into Iran, Turkey, and finally Europe. Whilst this part of the journey may have been less dangerous, it is not entirely without its perils.28. The underlined word “it” in the first paragraph refers to ________.A. making huge profitsB. traveling the Silk RoadC. exchanging goods and ideasD. connecting different civilizations29. Why was the Gobi Desert easier to cross than other deserts?A. The desert’s surface was easier to walk on.B. Camels for transportation were easier to find.C. It was smaller and could be crossed in less time.D. There were more natural water sources available.30. What can we guess about the rest stops in the Gobi Desert?A. Travelers were offered free accommodation.B. They were located around the edges of the desert.C. Travelers staying there were often attacked by criminals.D. They were shared by travelers from different countries.31. What is the passage mainly about?A. The origins of the Silk Road.B. The benefits of the Silk Road.C. The difficulties faced by Silk Road travelers.D. The cultural exchanges among Silk Road travelers.DLet’s begin with the story: King Hiero contracts the ancient Greek polymath Archimedes (阿基米德) to detect fraud in the manufacture of a golden crown. Archimedes accepts the challenge and, during a subsequent trip to the public baths, realizes that the more his body sinks into the water, the more water is displaced—making the displaced water an exact measure of his volume. Realizing he has hit upon a method to determine whether the King’s crown was made of gold or silver, the young Greek leaps out of the bath and rushes home naked crying “Eureka! Eureka!” Or, transla ted: “I’ve found it! I’ve found it!”Too bad, however, Archimedes probably never uttered the phrase in that way.First and foremost, Archimedes himself never wrote about this episode, although he spent plenty of time detailing the laws of buoyancy (浮力). The oldest authority for the naked-Archimedes eureka story is Vitruvius, a Roman writer, who included the tale in his introduction to his ninth book of architecture. “Vitruvius may have gotten it wrong,” says Chris Schmitt, a mathematician at the University of Berlin and a self-described Archimedes fan. “The method attributed to Archimedes in the story works in theory so it sounds right, but when you actually try it, you find that the real world gets in the way.”In fact, Schmitt is one of a long line of scientists, including Galileo, who have read the account and thought, “That can’t be right.” As Galileo wrote, Archimedes could have achieved a far more precise result using his own law of buoyancy and an accurate scale. In fact, the surface tensi on of water can make the volume of a light object like a crown immeasurable. “There may be some truth to it,” Schmitt adds. “Archimedes did measure the volume of things but the eureka moment was maybe due to his original discovery concerning buoyance, not to sitting in the bathtub and then running through the streets naked.”Much like Newton’s apple, the exclamation persists because of the enduring power of the story: a golden crown, a life in the balance, a naked mathematician. The suspect foundations of the eureka moment take nothing away from the word’s ability to uniquely and concisely convey the flash of inspiration.32.According to the first paragraph, how would Archimedes measure the volume of the crown?A.He would weigh himself with and without the crown.B.He would weigh the crown first and then put it into water.C.He would go to the public baths wearing the crown on his head.D.He would sink the crown into water and measure the water displaced.33.What did Galileo probably think of the naked-Archimedes eureka story?A.He believed the word “eureka” was said in another situation.B.He suspected Archimedes didn’t run through the street naked.C.He doubted Archimedes carried out the experiment independently.D.He thought Archimedes would not have used the method described.34.What can be inferred from the underlined sentence in the last paragraph?A.The word “eureka” is still widely used today.B.The word “eureka” is now a formal scientific term.C.Most people accept the authenticity of the original story.D.People are still inspired by the achievements of Archimedes.35.What is the purpose of this text?A.To introduce the famous scientist Archimedes.B.To examine the credibility of the eureka story.C.To explain how the word “eureka” was created.D.To urge people not to use the word “eureka” anymore.第二节( 共5小题; 每小题2分，满分10分)根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。

Regarded as the “Lungs of Central China", the forest coverage reaches over 90 percent of the area. Due to the special climate, it is neither too hot in summer nor too cold in winter. Sometimes clouds stretch around mountains, rewarding tourists with unforgettable views. Besides, the area is home to some rare animals such as golden monkeys, white bears and antelope.The Three-Gorge Tribe scenic spotLocated in the area of the Xiling Gorge in the city ofYichang, it has the beauty of landscape paintings. The spot is a “ProtectedCenterof the Popular Culture and Art of the Three Gorges”.

Most plastic is made from fossil fuels. Millions of tons of greenhouse gas are released from the development of these resources and plastic production and burning.The end life of plastic is just worrisome. Less than 10% of the plastic produced has been recycled. Even more of it has been burned. But the vast majority of plastic has been buried inland, and it is increasingly polluting the environment. We hear mostly about ocean plastic and the harm done to sea creatures that mistake plastic bags and bits for food. But microplastic is even more worrisome. Plastic doesn't break down biologically but instead breaks down into tiny particles（a very small piece of something）, which have been found in every corner of the planet, on land and in the air, in drinking water and food sources.Yet the public has not given this global environmental disaster the attention it requires. Instead, they have viewed single-use plastic—which makes up about 40% of plastic used each year—as a litter issue that can be solved through better recycling and waste management. That attitude must change because the recent global breakdown of the market for recycling has made it clear that it has never been, nor ever will be, able to keep up with plastic trash use.California has been the forerunner of plastic waste reduction—it was the first state to ban single-use plastic bags and may be the first state to transform the way goods are packaged. The state also came close to passing an act which would have required that products sold in plastic packaging in the state have a proven recycling rate of 75% by 2032. California, though influential, can't solve this crisis alone. The US has long been producing a greatamount of plastic trash and it should engage in reducing the use of plastic as well.4. Why does the author mention the release of greenhouse gas in paragraph 1?A. To show the harm of plasticB. To warn of the climate change.C. To call for the development of fossil fuels.D. To highlight the importance of plastic equipment.5. What's the author's attitude towards the public opinion on single-use plastic?A. Favorable.B. Tolerant.C. Curious.D. Opposed.6. What's California's role in reducing plastic waste?A. A pioneer.B. A failure.C. An objector.D. A predictor.7. What can be the best title for the text?A. Microplastic Products Are HarmfulB. Waste Recycling Is an Urgent MatterC. Plastic Waste Pollution Is a Wake-up CallD. Global Environmental Disasters Are IncreasingCWith graduation days being celebrated all over the country, a student who has to use a wheelchair honored his mother on his graduation day in a special way. Easley High School graduate, Alex Mays surprised people present when he got up and walked across the stage at Clemson's Littlejohn Coliseum.“I was really happy—it made me feel good,” Alex said.Alex was not given a chance to live right from his birth. He was born at 25 weeks and weighed just 1 pound, 10 ounces at birth. When he was very young, he had a disease and lost the ability to walk. After his mother's death in 2013, Alex had several other difficult life changes until he came to live with his grandparents, Dousay and her husband, Dewayne. Dousay said that when Alex came to live with them, they decided to bring him up in the best possible way they could.Last fall, Alex said that he would walk across the stage to get his diploma to honor his late mother. He practiced hard and worked with a physical therapist for 9 months to complete his plan.The only help Alex got was from his mom's best friend, Tonya Johnson, who pushed his wheelchair to thestage wearing one of his mother's favorite shirts. “I had support from my family. I couldn't have done it without them,” Alex said.“Alex made everyone in the building feel encouraged that day” Pickens County School District public information specialist John Eby said. “The school teachers knew he was going to get up to get his diploma, but the distance he walked was a surprise, even to them,” Eby said.“Some of life's most important tests aren’t given in a classroom; Alex tested himself and passed with flying color1 s,” Eby added.8. In what way did Alex honor his late mother on his graduation day?A. By dressing like her.B. By saying sorry to her.C. By inviting her best friend.D. By walking to get his diploma.9. What can we learn from Paragraph 3?A. Alex was born healthy.B. Alex went through a lot.C. Alex had a purpose in life as a child.D. Alex has lived with his grandparents all the time.10. What did Alex also express on his graduation day?A. His big regret in life.B. His feelings for hisschool.C. His thanks for his family.D. His will to complete his study.11. Which of the following words can best describe Alex?A. Strong-minded.B. Warm-hearted.C. Cool-headed.D. Easy-going.DIn Colombia a group, named WebConserva, is carrying out a project in the San Lucas Mountains with the help of coffee growers.The San Lucas area is one of the most unexplored places in Colombia, which is home to many thousands of species of animals and plants. Yet gold mining and coca farming have dealt a blow to its ecosystem. To limit additional development in the San Lucas area, the group helps coffee growers by linking them with processors from around the country.Colombia has more different kinds of living things than any other country except neighboring Brazil. In 2016, the Colombian government signed a peace deal with the Revolutionary Armed Forces of Colombia ending years of civil war. As a result, more land became accessible for use, with deforestation(毁林) coming along. Government information shows that in 2017, almost 220,000 hectares of forest were destroyed compared to around 124,000 hectares in 2015.To date, the project includes 10 families who farm 400 hectares of coffee plants, which costs about $77,000 dollars a year. WebConserva hopes that, in time, 200 families will be included. At that level, 20,000 hectares of untouched forest could be protected. In San Lucas, the families promise not to cut down trees to expand their crops or to hunt wild animals from the forests. In return, they receive $ 250 to $ 300 per 125 kilograms of coffee, an enviable amount there. Arcadio Barajas is among those taking part. His new coffee plantation(种植园) makes a barrier between cattle farms and forests where wild animals like the jaguar live and hunt. In this way, he doesn't have to kill wild animals to protect his cattle.Barajas said that pulling down the forest to plant coca and killing wildlife were against his will. Now he feels that growing coffee lets him be astewardof the land. "I'm taking care of the environment, the forest and the animals," he said.12. Why does WebConserva set up the project?A. To help local farmers make money.B. To expand areas of coffee growing.C. To link processors with coffee growers.D. To conserve biodiversity in the Mountains.13. What happened after Colombia’s civil war was over?A. Colombia helped many needy families.B. Colombia lost lots of areas of forests.C. Colombia started to save damaged forests.D. Colombia became more peaceful than Brazil.14. Which is probably a function of Barajas's coffee plantation?A. A method of protecting cattle and wildlife.B. A substitute for hunting of wild animals.C. A barrier between man and wild animals.D. A shelter for cattle against human hunters.15. What does the underlined word "steward" mean in the last paragraph?A. Farmer.B. Master.C. Guardian.D. Explorer.第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。

The oldest authority for the naked-Archimedes eureka story is Vitruvius, a Roman writer, who included the tale in his introduction to his ninth book of architecture. “Vitruvius may have gotten it wrong,” says Chris Schmitt, a mathematician at the University of Berlin and a self-described Archimedes fan. “The method attributed to Archimedes in the story works in theory so it sounds right, but when you actually try it, you find that the real world gets in the way.”In fact, Schmitt is one of a long line of scientists, including Galileo, who have read the account and thought, “That can’t be right.” As Galileo wrote, Archimedes could have achieved a far more precise result using his own law of buoyancy and an accurate scale. In fact, the surface tensi on of water can make the volume of a light object like a crown immeasurable. “There may be some truth to it,” Schmitt adds. “Archimedes did measure the volume of things but the eureka moment was maybe due to his original discovery concerning buoyance, not to sitting in the bathtub and then running through the streets naked.”Much like Newton’s apple, the exclamation persists because of the enduring power of the story: a golden crown, a life in the balance, a naked mathematician. The suspect foundations of the eureka moment take nothing away from the word’s ability to uniquely and concisely convey the flash of inspiration.32.According to the first paragraph, how would Archimedes measure the volume of the crown?A.He would weigh himself with and without the crown.B.He would weigh the crown first and then put it into water.C.He would go to the public baths wearing the crown on his head.D.He would sink the crown into water and measure the water displaced.33.What did Galileo probably think of the naked-Archimedes eureka story?A.He believed the word “eureka” was said in another situation.B.He suspected Archimedes didn’t run through the street naked.C.He doubted Archimedes carried out the experiment independently.D.He thought Archimedes would not have used the method described.34.What can be inferred from the underlined sentence in the last paragraph?A.The word “eureka” is still widely used today.B.The word “eureka” is now a formal scientific term.C.Most people accept the authenticity of the original story.D.People are still inspired by the achievements of Archimedes.35.What is the purpose of this text?A.To introduce the famous scientist Archimedes.B.To examine the credibility of the eureka story.C.To explain how the word “eureka” was created.D.To urge people not to use the word “eureka” anymore.第二节( 共5小题; 每小题2分，满分10分)根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。
