If you thought the toilet paper shortage was bad, just wait. Meat may be next in America. 1., John H. Tyson, chairman of the board of Tyson Foods, warned that the COVID-19 pandemic is forcing the company to shut all the stores across the country. “This means one thing,” he wrote. “2. As pork, beef, and chicken plants are being forced to close, even for short periods of time, millions of pounds of meat will disappear from the supply chain.” The ripple effect will make its way to consumers, Tyson noted, as “There will be limited supply of our products available in grocery stores until we are able to reopen our facilities that are currently closed.” The Tyson plant in Waterloo, Iowa, was one that closed, having been linked to 182 cases of the coronavirus, which is nearly half the entire county's total. In addition to that facility, pork processing plants for Smithfield Foods in Sioux Falls, South Dakota, and JBS in Worthington, Minnesota, also closed indefinitely earlier this April.3. The U.S. Department of Agriculture (USDA) reported record-high red meat, beef, and pork production in March. However, according to the United Food and Commercial Workers International Union, representatives of more than 250,000 industry workers, slaughter(屠宰) capacity is trending down 25% for pork and 10% for beef as 13 plants have closed. 4. In a report, Julie Niederhoff, an associate professor of supply chain management at Syracuse University, was optimistic. “We’re not going to run out of food. 5.” Also, Niederhoff claimed that the state of the food chain remains enough, despite shortage of a particular brand or type of food. A.Demand from consumers is rising as many are sheltering at home. B.The food supply chain is fragile. C.The government will take some measures. D.Because some of its 100,000 workers have fallen ill. E.The COVID-19 pandemic is very serious. F.These three plants make up about 15% of pork production in the U.S.. G.We’re going to run out of maybe your one particular favorite food.
He looked like a pirate. With his handkerchief tied in a knot behind his little nine-year-old head, he looked like a pirate, a sad pirate. The first time little David came to our camp, he was hairless and worn out from medical treatments. He was also very angry. Paul Newman's camp counselors (指导老师 ) were hoping to fill David's days with fun and laughter. But David stayed inside himself, wanting to be alone, or in a corner of the cabin. At this camp for children with life-threatening illnesses, we had seen some pretty tough children worn out by cancer recover full of energy despite their illness. But we saw little progress in David no matter what we tried with him. Five days into the eight-day session saw a quiet, sad little pirate. Then something happened on that fifth night. Something at camp that we would call "huge". It was cabin night. That's the time when campers and counselors spend lime together in each individual cabin instead of an all-camp activity. Campers love cabin nights because there's always a bedtime snack. On the cabin table that night were bags of potato chips. David slowly walked over to the table, leaving his comer to join the rest of us. He took one of the bags of the potato chips and started smashing(弄碎) it with his little fists, as all the other campers looked on in disbelief, I wondered what the cabin counselor would do. The college-age volunteer counselor positioned a bag of chips on die table in front of himself, and he, too, started smashing it with his fist. The campers went crazy as everyone ran to the table to get in on the fun of smashing potato chips with their fists. Somehow everyone knew, everyone sensed, that anger within him was now being released. For the last couple days of the session, David was a different kid. He was a little nine-year-old boy again, trying to fill the hours of each remaining day at camp with as much fun as could be possible. Several days after the session, David came back again. This time, there wasn't anything he wouldn't try to fit in to his day. He sure was having a great time at camp. David asked me if I needed an altar(祭坛)boy when I celebrated Mass in the woods. Sure enough, he was my altar boy. I remembered how carefully he listened to me when I talked about death. 1 said it's only a doorway. You walk through the door and there's the Lord God and behind God a whole line of people waiting to hug you. After Mass, he said to me, "Hey Fatha, a door, huh?" A couple more days of fun passed and tonight was the talent show. The tradition is that campers and counselors dress up in costumes, and everyone gets a standing applause for singing and dancing or simply just acting like fools on stage. The show had begun: lights, camera, action. Unfortunately, the only action taking place in our row of seats was little David making his way from counselor to counselor to say an early good-bye to camp. He had become quite ill and had to go to the hospital because of this new crisis. When this little nine-year-old pirate stood in front of me, he gave me a hug and a big wet kiss on my cheek. 1 was crying. He was crying. A whole row of counselors was in tears. After the hug and kiss, he put his hands on my shoulders, and tears still in his eyes, said: "See you on the other side of the door, Fatha." 1.The camp counselors failed to fill David's beginning days with fun and laughter, mainly because David_____. A.behaved like a pirate B.remained in a bad mood C.was left alone at the camp D.was teased by other campers 2.Seeing David smashing the potato chips, the counselor did the same thing in response because he _____. A.would like David to eat more of them B.hoped all the other campers would join C.found it possible to help David release anger D.wanted to show that he was as angry as David 3.What can we learn from this article? A.The camp was intended for those talented in singing and dancing. B.The purpose of the camp was to give diseased children caring love. C.The camp was popular among the children who enjoyed their vacation here. D.Medical treatment could be provided to diseased children at the camp. 4.Which of the following does NOT show the change in David? A.David came back to the camp for a second session after the first ended. B.David had become quite ill and had to go to the hospital because of this new crisis. C.David made his way from counselor to counselor to say an early good-bye to camp. D.David stood in front of me and gave me a hug and a big wet kiss on my cheek. 5.What do you think the theme of the story is? A.Children with deadly diseases are usually difficult to get along with. B.People should have patience with children with life-threatening illnesses. C.People should tell children with life-threatening illnesses to care nothing about death. D.Love and proper guidance can help people look at something negative in a positive way.
Summer brings flowers and dirt and barbeque smoke. In the most wintery places, there isn’t much outside on cold days except snow, strong wind and cars warming up. Pine needles, wood smoke and snow---these are the smells of winter, and for people who live with different seasons, wintry weather brings its own set of olfactory(嗅觉的) experiences. But why does the cold of winter smell different from the heat of summer? One reason is that odor (气味) molecules move much more slowly as the air temperature drops, said Pamela Dalton, an olfactory scientist at the Monell Chemical Senses Center in Philadelphia. That means that there are simply fewer smells to smell on a cold, crisp day than there are on a hot and humid one. It’s the same reason why hot soup smells more than cold soup does and why the garbage truck leaves behind the strongest smells on steamy summer days. What’s more, our noses don’t work quite well when the surrounding air is cold, Dalton said. In experiments that require biopsies(活组织检查) of olfactory receptors that lie deep inside the nose, researchers at Monell have discovered that the receptors “bury themselves a little more deeply in the nose in winter,” she said, “possibly as a protective response against cold, dry air.” There is a strong psychological factor in our sense of smell, Hirsch added, and what we expect to smell has a big influence on what we actually smell. In The Invalid’s Story by Mark Twain, for example, a man is stuck on a train next to what he thinks is a rotting dead body but is actually a box of cheese that smells extremely unpleasant. So strongly affected by the smell, he spends too long looking for fresh air on the freezing platform and develops a fever that ends up killing him. “What you think of a smell have powerful effects on you whether you like it and whatever you think it to be,” Hirsch said. “So, if you go outside in winter and you are used to smelling snow or nuts in the fire or whatever you happen to smell outside, that’s what you will interpret smells to be.” To cope with lack of smells in winter, many people try to burn more candles with pleasant smell, cook more sweet stews(炖菜) and bake more cookies, which creates a greater contrast between the indoor and outdoor environments. “You’re probably fond of indoor smells in the winter,” Dalton said. “Homes are closed up, and windows are closed. We concentrate on the smells of cooking and living.” 1.According to the second paragraph, Pamela Dalton will probably agree that _________. A.air temperature affects smells’ spreading direction greatly B.hot soup is more popular with people in winter than cold soup C.there are not many smells available to be smelled in winter D.a garbage truck is easier to break down in cold winter 2.The author used the story written by Mark Twain to show that _________. A.one can easily feel terrible smell in a small space B.one’s mind and thoughts can affect the sense of smell C.no one can survive when there is lack of fresh air D.one’s opinion on smell is quite different from others 3.Which of the following is NOT the measure people take to deal with lack of smells in winter? A.Closing doors and windows B.Cooking stews C.Burning candles D.Baking cookies

阅读下面短文，根据所给情节进行续写，使之构成一个完整的故事。 About ten years ago, my wife and I took a trip to the Grand Canyon in Arizona. I didn't like to carry all my keys in my pocket during a hike, so I took away the key to the car and left the rest in the car. When we came back, I put the key somewhere in the car without reattaching it to the key ring. Then we made a fire, cooked some food, and went to sleep in the back of the SUV. The next morning, we were cleaning up our campsite when I saw a bird inside my car. I walked over, and it flew away. When we got in the car to go home, I couldn't find the key. We searched and searched even emptying out the car completely, but it was gone. Then it hit me that the bird must have taken it. After all, those birds are known for stealing shiny things and decorating their nests with them. Keys are shiny. The bird was the thief! It made perfect sense to me. So I decided to find its nest. But there is a problem: As everyone knows, the Grand Canyon is a little large in area, so I didn't like my chances of actually finding a certain nest belonging to a certain bird in a certain tree in all that space. But what other choice did I have? My wife was not encouraging me. She said, “Are you crazy? You'll never find it! The Grand Canyon is the biggest hole on Earth!” I didn't answer and walked steadily forward until her laughter died away. I struggled to keep hope as I searched dozens of trees and tracked every singing bird. It was like searching a needle in the sea. But, oh, how great my victory would be when I held the missing key from the bird's nest. 注意: 1.所续写短文的词数应为150左右； 2.至少使用5个短文中标有下划线的关键词语: 3.续写部分分为两段，每段的开头语已为你写好； 4.续写完成后，请用下划线标出你所使用的关键词语。 Paragraph l: After two hours of searching, I finally gave up and returned to the car. _________________________________________________________________________________________________________________________________________________________________________________________________________________________ Paragraph2: The next day, we stopped at a service centre for lunch. _________________________________________________________________________________________________________________________________________________________________________________________________________________________

Haw wondered why he had always thought that a change would lead to something worse.Now he realized that change could lead to something better. “Why didn't I see this before?”he asked himself. Then he raced through the Maze with greater strength and agility.Before long,he found a Cheese Station and became excited as he noticed little pieces of New Cheese near the entrance. They were types of Cheeses he had never seen before,but they looked great.He tried them and found that they were delicious.He ate most of the New Cheese bits that were available and put a few in his pocket to have later and perhaps share with Hem.He began to regain his strength. He entered the Cheese Station with great excitement.But,to his disappointment,he found it was empty.Someone had already been there and had left only the few bits of New Cheese. He realized that if he had moved sooner,he would very likely have found a good deal of New Cheese here. Haw decided to go back and see if Hem was ready to join him. As he retraced his steps,he stopped and wrote on the wall: The quicker you let go of old cheese,the sooner you find new cheese. After a while,Haw made his way back to Cheese Station C and found Hem.He offered Hem bits of New Cheese,but was turned down. Hem appreciated his friend's gesture but said,”I don't think I would like New Cheese.It's not what I'm used to.I want my own Cheese back and I'm not going to change until I get what I want.” Haw just shook his head in disappointment and reluctantly went back out on his own.As he returned to the farthest point he had reached in the Maze,he missed his friend,but realized he liked what he was discovering.Even before he found what he hoped would be a great supply of New Cheese,if ever,he knew that what made him happy wasn't just having Cheese. He was happy when he wasn't being run by his fear.He liked what he was doing now. Knowing this,Haw didn't feel as weak as he did when he stayed in Cheese Station C with no Cheese.Just realizing he was not letting his fear stop him,and knowing that he had taken a new direction,nourished him and gave him strength. Now he felt that it was just a question of time before he found what he needed.In fact,he sensed he had already found what he was looking for. He smiled as he realized: It Is Safer To Search In The Maze Than Remain In A Cheseless Station Haw realized again,as he had once before,that what you are afraid of is never as bad as what you imagine.The fear you let build up in your mind is worse than the situation that actually exists. He'd been so afraid of never finding New Cheese that he hadn't even wanted to start looking. But since starting his journey,he had found enough Cheese in the corridors to keep him going. Now he looked forward to finding more.Just looking ahead was becoming exciting His old thinking had been clouded by his worries and fears. But that had changed in the days since he had left Cheese Station C. Now he realized it was natural for change to continually occur,whether you expect it or not change could surprise you only if you didn't expect it and weren't looking for it. When he realized he had changed his beliefs,he paused to write on the wall: Old Beliefs Do Not Lead You To The New Cheese Haw hadn't found any Cheese yet,but,as he ran through the Maze,he thought about what he had already learned. Haw now realized that his new beliefs were encouraging him to behave in a new way.He was behaving differently from the way he had when he had kept returning to the same cheeseless station. He now knew that when you change what you believe,you change what you do. You can believe that a change will harm you and resist it.Or you can believe that finding New Cheese will help you,and embrace the change. It all depends on what you choose to believe. He wrote on the wall: When You See That You Can Find New Cheese,You Change Course 1.From the first eight paragraphs,it can be concluded that A.Haw was eager to eat up all Cheese bits. B.Haw cared much more about himself than Hem. C.Haw had been reluctant to change himself before. D.Haw has been dreaming of himself enjoying Cheese. 2.The sentences Haw wrote on the wall are intended to show A.Haw would inspire others to make changes with him. B.Haw had a strong desire to find New Cheese to share with Hem. C.Haw wanted Hem to find him by following the tracks on the wall. D.Haw has been changing his mind and action to reach his goal gradually. 3.Which of the following can express the main idea of the passage? A.Old habits die hard. B.A diversity leads to prosperity. C.Action speaks louder than words. D.Someone barks up the wrong the tree. 4.From the passage, which words can be used to describe Haw? A.Stubborn but selfless. B.Caring and ambitious.

Air pollution may be causing baldness, scientists have shown for the first time. A new study found that fine particulate matter emitted by cars would damage the skin that holds hair follicles (毛囊) in place. A series of laboratory tests on human cells showed that levels of the crucial proteins needed for hair to grow and be retained decreased when they were exposed to pollution particles. While there is a growing body of evidence showing how these tiny particles can damage internal health, including by entering the bloodstream through the lungs, this is the first to demonstrate such a risk to the surface of the body. The study was conducted by exposing cells from the human follicle dermal papilla cells(HFDPCs), to various concentrations of PM10-like dust and diesel particles (柴油颗粒). After 24 hours the researchers performed a process, known as western blotting, to detect the levels of specific proteins in the cells. The results showed that the presence of PM10 and diesel particles decreased levels of B-catenin, the protein responsible for hair growth. The study also revealed that the levels of three other proteins — cyclin D1, cyclin E and CDK2, which are responsible for hair growth and hair retention, were decreased by PM10-like dust and diesel particles in a “dose-dependent” manner. Dr Hyuk Chul Kwon, who led the study at the Future Science Research Centre, said, “While the link between air pollution and serious diseases such as cancer and lung diseases is well established, there is little-to-no research on the effect of particulate matter exposure on the human skin and hair in particular. Our research explains the mode of action of air pollutants on HFDPCs, showing how the most common air pollutants lead to hair loss.” Sources of PM include the burning of fossil fuels — petrol and diesel, as well as other solid fuels,and other industrial activities such as building, mining and the manufacturing of building materials like bricks. “While it is difficult to escape from the surrounding pollution, limiting the time for walking in busy streets, especially during rush hour, should help reduce exposure,” said Dr Kwon. “If you are exercising outdoors, try to do so in areas that are less polluted and do not spend too much time waiting at traffic hot spots such as traffic lights.” 1.What did the new study find?

Cells in our brain usually send a “stop eating” signal when we've eaten enough. But in a study, researchers found that after mice ate fatty food for just two weeks, their brains brake on overeating failed. Researchers at the University of Washington in Seattle conducted the study.They shared their findings in Science.Garret Stuber is a professor at the University of Washington.He and his team mainly focused on one brain area known-to be connected with eating behavior.This brain area contains many different kinds of cells.Researchers noticed big differences between the glutamatergic nerve cells(谷氨酸神经细胞)of the fat mice and those of the thin mice.And the earlier work by Stuber's group had suggested that these cells act like a brake on overeating.When the researchers stopped these cells from working,mice suddenly overate.They also fattened up. But it wasn't clear how these cells' activity changed as the mice changed from being slim to being fat. “Being fat doesn't just happen overnight,”notes Stuber.To study that gradual fattening up,his group did a new study.They fed mice with high-fat food.Now and again,they used a microscope to look at how well the animals 'glutamatergic nerve cells could send out signals.During the process,they found the activity of these glutamatergic nerve cells slowed,even before the mice became fat.That cell sluggishness(怠惰)continued as the mice grew larger over a 12-week period. The results suggest that the high-fat diet is removing the brake on overeating and becoming fat,”says Stephanie Borgland,a professor at the University of Calgary in Canada. Stuber's group doesn't know whether these brain cells will go back to normal if the mice stop eating the fatty food and slim down.It would be hard to keep monitoring the same cells over the months it would likely take for the mice to return to a healthy body weight,”explains Stuber.And it's hard to say whether similar cells control the same thing in humans. “Having high-fat diets probably affects a much wider family of cells than those studied here,” Stuber notes. “Changes,” he says, “are probably happening across the brain.” Understanding those things might help us find better ways of limiting overeating. 1.What did researchers find in the study? A.Mice tended to become sluggish if they often overate. B.Having high-fat diets affected many kinds of brain cells. C.Mice began to overeat after eating fatty food for a period. D.The number of brain cells would drop when mice overate. 2.Why was a new study conducted? A.To prove that fatty food was bad for health. B.To know more about that gradual weight-gain. C.To collect more information about the mice 's cells. D.To observe how long it would take for the mice to grow fat. 3.What does the last but one paragraph mainly show? A.It's still difficult to answer some questions. B.It's hard to find the similar brain area in humans. C.It's wrong to apply what suits animals to humans. D.It's necessary to keep monitoring the mice for long. 4.Where is this text most likely from? A.A personal diary. B.A useful guidebook. C.A science magazine. D.An adventure novel
Fire Prevention Information The University of Adelaide employs a full-time staff of fire prevention professionals. They inspect all campus buildings and test and maintain all sprinkler(喷水灭火装置)systems, fire alarms and fire extinguishers(灭火器).They also provide educational programs or fire safety in the residence hall. Whenever you move to a new area, you should locate the fire alarm purl stations and the two exits nearest your room. Fire Alarms The floors of all campus buildings are equipped with manual fire alarm systems which include fire alarm pull stations and pipes.Most are also equipped with automatic fire alarm systems consisting of heat detectors,smoke detectors and sprinklers.For your safety,never tamper with(胡乱摆弄)these systems.False fire alarms are illegal and may lead to imprisonment. Fire Drills A fire drill will be conducted in your residence hall every semester.During a fire drill,please do the following: Take your room key and ID,close and lock the door to your room. Exit immediately from the nearest emergency exit;do not use a lift. Meet outside of your residence hall and wait for further instructions. Fire Extinguishers Fire extinguishers are located on each floor and in each apartment.Use a fire extinguisher only if you have been trained to do so.Irresponsible use of a fire extinguisher can create a dangerous situation for other residents and could result in damage to personal property.Misuse of a fire extinguisher will result in fines. Smoke Detector A smoke detector is on the ceiling in your room.Some buildings also have heat detectors on the ceilings.Do the following to ensure the safe operation of your smoke detector: If your smoke detector is working properly,the red light should be on.If the red light is not blinking(闪动)，contact residence hall staff immediately. Do not cover or block your smoke detector in any way. If a smoke detector sets off an alarm and there is no fire or smoke,inform your hall staff. 1.What is the main duty of the fire prevention professionals? A.To provide part-time jobs for students. B.To lead the students to the nearest exits. C.To check and maintain fire prevention equipment. D.To train teachers to be fire prevention professionals.. 2.What do the automatic fire alarm systems include? A.Pipes and smoke detectors. B.Smoke detectors and sprinklers. C.Fire alarm pull stations and pipes. D.Sprinklers and fire alarm pull stations 3.What do we know about the use of fire extinguishers? A.Using them wrongly results in punishment.
