1 . A schoolgirl saved her father’s life by kicking him in the chest after he suffered a serious allergic (过敏的) reaction which stopped his heart.Izzy, nine, restarted father Colm’s heart by stamping (踩) on his chest after he fell down at home and stopped breathing.Izzy’s mother, Debbie, immediately called 999 but Izzy knew doctors would never arrive in time to save her father, so decided to use CPR.However, she quickly discovered her arms weren’t strong enough, so she stamped on her father’s chest instead.Debbie then took over with some more conventional chest compressions (按压) until the ambulance arrived.Izzy, who has been given a bravery award by her school, said, “I just kicked him really hard. My mum taught me CPR but I knew I wasn’t strong enough to use hands. I was quite scared. The doctor said I might as well be a doctor or a nurse. My mum said that Dad was going to hospital with a big footprint on his chest.”“She’s a little star，” said Debbie, “I was really upset but Izzy just took over. I just can’t believe what she did. I really think all children should be taught first aid. Izzy did CPR then the doctor turned up. Colm had to have more treatment on the way to the hospital and we’ve got to see an expert.”Truck driver Colm, 35, suffered a mystery allergic reaction on Saturday and was taken to hospital, but was sent home only for it to happen again the next day. The second attack was so serious that his airway swelled, preventing him from breathing, his blood pressure dropped suddenly, and his heart stopped for a moment.He has now made a full recovery from his suffering.
What’s the right order of the events?
①Izzy kicked Colm. ②Debbie called 999.③Izzy learned CPR. ④Colm’s heart stopped.

2 . In many countries of the world, people can confidently tell you the meaning of their town or city, but most people who live in Manchester, Oxford or Birmingham would not be able to explain what the name of their city means. The name of every British town and city, however, has a long history. Two thousand years ago, most people living in Britain were Celts........This is why there are so many place names in England which end in “-chester” or “-caster” –Manchester, for example. ..........The Romans never reached Wales or Scotland, and many place names there are Celtic.........After the Romans left Britain, it was attacked by tribes called the Anglo-Saxons who were from the area of Europe that is now Germany and Holland............Twelve hundred years ago, the Vikings came to England from Scandinavia. They traded with the Anglo-Saxons but lived in their own villages. ........Finally, in 1066, England became Norman — the Normans gave us the place name “grange”, which means farm.........
Which of the following shows the correct order of the arrival of inhabitants in Britain?
| A．The Celts –The Romans – The Vikings –The Normans –The Anglo Saxons |
| B．The Romans –The Celts –The Vikings –The Anglo Saxons–The Normans |
| C．The Celts –The Romans –The Anglo Saxons–The Vikings –The Normans |
| D．The Romans –The Anglo Saxons–The Celts –The Normans –The Vikings |

4 . The history of microbiology begins with Dutch cloth maker named Antoni van Leeuwenhoek, a man of no formal scientific education. In the late 1600s. Leeuwenhoek, inspired by the magnifying lenses（放大镜）he used to examine cloth, built some of the first-microscopes. He developed technique to improve the quality of tiny, rounded lenses, some of which could magnify an object up to 270 times. After removing some plaque from between his teeth and examining it under a lens, Leeuwenhoek found tiny twisting creatures, which he called “animalcules”.
His observations, which he reported to the Royal Society of London, are among the first descriptions of microbes（微生物）. Leeuwenhoek discovered an entire universe invisible to the human eye. He found different microbes in samples of pond water, rain water, and human blood. He gave the first description of red blood cells, observed plant tissue, examined muscle, and investigated the life cycle of insects.
Nearly two hundred years later, Leeuwenhock’s discovery of microbes helped French chemist and biologist Louis Pasteur to develop his “theory of disease”. This concept suggested that disease originates from tiny organisms attacking and weakening the body. Pasteur’s theory later helped doctors to fight infectious diseases including anthrax, diphtheria, polio, smallpox, tetanus, and typhoid. All these breakthroughs were the result of Leeuwenhoek’s original work. Leeuwenhoek did not foresee this legacy.
In a 1716 letter, he described his contribution to science this way: “My work, which I’ve done for a long time, was not pursued in order to gain the praise I now enjoy, but chiefly from a strong desire for knowledge, which I notice resides in me more than in most other men. And therefore; whenever I found out anything remarkable, I have thought it my duty to put down my discovery on paper, so that the scientific community might be informed thereof.”

5 . Bricks are one of the oldest known building materials, dating back thousands of years. But researchers at Washington University in St. Louis have found a new use for bricks: as energy storage units. A team of engineers and chemists have found a way to transform an ordinary house brick into a pseudo-battery — allowing it to conduct and store electricity. The bricks are powerful enough to illuminate（点亮）an LED light bulb and cost only about $ 3 to make.
“I love the idea of adding value to things that are inexpensive, things that are affordable, things that we kind of take for granted, ”said Julio D’Arcy, an assistant professor of chemistry at Washington University and one of the researchers on this project.
The brick battery relies on the reddish pigment（色素）known as iron oxide, or rust, that gives red bricks their color. The scientists pumped the bricks with several gases that react with iron oxide to produce a network of plastic fibers. These microscopic fibers coat the empty spaces inside the bricks — and conduct electricity.
“What we’re trying to do is: we’re trying to make specialized plastics that are only used on the nano（纳米）scale — where we use very little of the plastic, and we can actually insert that plastic inside construction materials. ” The study is in the journal Nature Communications.
In the future, D’Arcy says, a brick wall could potentially serve a double purpose: providing structural support and storing electricity generated from renewable energy sources, such as solar panels.
The technology is still at least a few years away from being ready for the commercial market. And right now the energy storage capacity of the bricks is still pretty low — about 1 percent of a lithium battery. But the team is now testing ways to improve brick performance — because it looks like you can teach an old brick new tricks.

6 . When I was young at school, I loved to talk, which was not appreciated by Miss Jordan, my tenth-grade English teacher.
She wasn't a popular teacher because she was not good-looking and was so strict. Whenever she got upset, she would lower her head and look at you over the top of her glasses.
One day in her class, while I was busy talking, I didn't realize that she had stopped teaching. She stared straight at me. “Young lady, I would like to see you after school.”
For punishment she told me to write a thousand-word essay on education and it must be handed in by the following Wednesday. Well, that day came. I wasn't worried. It was a good paper. And I expected praise from her. The next day, however, she called me forward, looking at me over her glasses, and returned my paper. "Go back and rewrite. Remember, each paragraph must have a topic sentence." Then came the second time, the grammar. The third time, the spelling. The fourth time, the punctuation. The fifth, it wasn't neat enough. I was sick.
The sixth time, I rewrote the whole paper slowly, in ink, leaving generous space. Seeing it, she removed her glasses and smiled. She finally accepted the paper. After that, I put the whole thing out of my mind.
Two or three months passed, one day Miss Jordan said to us, “Class, do you still remember an essay contest held citywide? They have announced the winners. Yes, Mary has won the first prize."
I was amazed! It was the first time I had won a prize. Years later, I told a reporter the story and expressed my great thanks to Miss Jordan. Soon after that, I got a letter from Miss Jordan, and it said, "What I did wasn't that important. What mattered was the lesson you had learnt. When you wrote and rewrote that paper for me, you began to learn how to discipline yourself.”

7 . One night in March, five years ago, during happy hour at a bar in my hometown, I made a surprise announcement to my friends: I was going to shut down my law practice and attempt to travel around the globe in a year. What’s more, I would do it without taking any flights or making a single advance reservation of any kind. My announcement drew mixed reactions from my friends. Some offered support and encouragement, while others were more doubtful.
Once I’d said the words, there was no turning back. It took months to shut down my law practice and get things in order. Once I set off on my adventure in October 2016, I found that travelling without using planes was not easy. Trying to circle the globe in 16 months (it took me a bit longer than the initial 12 months I planned) made it even tougher. Even so, travelling overland was the most awe-inspiring way to truly understand the immensity of our wonderful planet.
I took three consecutive overnight buses to travel 3,000 km through Argentina, from Ushuaia, the world’s southernmost city, to the capital Buenos Aires. I would look out the windows for hours on end at the completely unspoiled plains, as if humans had never touched it.
It took seven consecutive days and nights on trains to get from Moscow to Beijing, each day spent gazing out the windows for hours as the West Siberian Plain swept by. Sometimes, I wouldn’t see a village or a human being for 10 hours. Later in my journey, it took 22 days on a cargo freighter to get from New Zealand through the Panama Canal and back to Philadelphia, to finish my round-the-world adventure.
It turned out that travelling with no reservations was far less difficult than I had imagined. Pulling into a city on a bus with a backpack, looking in a guidebook for a few suggestions of accommodations, and then finding an empty room was never much of a problem anywhere. It also kept me flexible and open about all my travel plans, which is advice I give everyone who asks—plan far less than you think you should.

8 . Yellowstone National Park became America’s first national park in 1872.The National Park Service was formed 44 years later. Yellowstone, which is mostly in the state of Wyoming, is considered as a great example of the National Park System. Humans have been present in Yellowstone for more than 11,000 years.
The first organized exploration of the area which lies close to the Continental Divide of North America took place in 1870.Those first organized explorers must have seen right away how special the land was. Yellowstone contains beautiful mountains, deep canyons, lakes and rivers.
The name Yellowstone comes from the river running through the area. At first known as Rock Yellow River, later it became known as the Yellowstone River. Yellowstone is home to many different species of plants. However, the park is most special because of what lies underneath it. It sits on top of an ancient super volcano. And it remains an active volcano. It is believed that the last time the volcano erupted was a half million years ago. The area has had three major eruptions in the last three million years. Experts say it may erupt again in another 1,000 to 10,000 years. But each year, there are thousands of earthquakes at Yellowstone. Most are too small to be felt by people visiting the park.
Yellowstone is filled with the beauty of many hot water springs. Of all the geothermal(地热的)places in the world, half are in Yellowstone. In places of geothermal activity, hot water and gases are trapped under the earth’s crust. In places like Yellowstone, they rush to the surface in the form of hot water and steam to form geysers(喷泉).There are more geysers and hot springs in Yellowstone than anywhere else on Earth. The most famous geyser is Old Faithful. It erupts about every hour or hour and a half. The eruption can last from one and a half minutes up to 5 minutes. The amount of hot water it pours in that time can be as much as 31,000 liters or more.

9 . It is difficult for doctors to help a person with a damaged brain. Without enough blood, the brain lives for only three to five minutes. More often the doctors can’t fix the damage. Sometimes they are afraid to try something to help because it is dangerous to work on the brain. The doctors might make the person worse if he operates on the brain.
Dr. Robert White, a famous professor and doctor, thinks he knows a way to help. He thinks doctors should make the brain very cold. If it is very cold, the brain can live without blood for 30 minutes. This gives the doctor a longer time to do something for the brain.
Dr. White tried his idea on 13 monkeys. First he taught them to do different jobs, then he operated on them. He made the monkeys’ blood back to the monkeys’ brains. When the brain’s temperature was 10℃, Dr. White stopped the blood to the brain.After 30 minutes he turned the blood back on. He warmed the blood again. After their operations the monkeys were like they had been before. They were healthy and busy. Each one could still do the jobs the doctor had taught them.
1. The brain operation was made possible mainly by ____.| A．taking the blood out of the brain | B．trying the operation on monkeys first |

10 . If you ever find yourself trapped in the wilderness without food, you'll have to figure out how to feed yourself. Many plants in the wild are edible, but many are also poisonous. So it is necessary to learn how to determine whether the plants you find can be eaten safely.
Avoid using this method without careful planning. Some plants can be deadly, and even if you follow these guidelines perfectly, there is always a chance that a plant will make you seriously ill. Prepare yourself for wilderness outings by learning about the local plants, and carry a guidebook to help you identify plants. Even if you are unprepared and cannot find food you know to be safe, remember that, depending on your activity level, the human body can go for days without food, and you’re better off being hungry than being poisoned.
Testing the plant in your mouth is dangerous, so go forward very slowly and carefully. First, hold a small portion of the prepared plant part against your lip for 3 minutes. Do not put the plant in your mouth. If you notice any burning, tingling (刺痛), or other reactions, discontinue testing. Second, place another small portion of the plant part on your tongue. Hold the plant on your tongue without chewing for 15 minutes. Discontinue testing if you notice any reaction. Third, chew the plant and hold it in your mouth for 15 minutes. Chew the plant well, and do not swallow. Discontinue testing if you notice any reaction. Fourth, swallow the small portion of the plant. Wait 8 hours. Do not eat or drink anything during this period except purified water. If you feel sick, immediately throw up what you eat and drink plenty of water. If activated charcoal (活性炭) is available, take that with the water.
