1 . 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.

2 . I was driving my newly acquired motorcycle across the vastness of North Dakota when all of the sudden it froze up on the road. I would later be told the belt had slipped and this caused one of the pistons(活塞) to crack a cylinder (气缸) head, or something like that.
Anyway, I sat on the side of the road for what seemed like hours. I even pretended to have been in an accident, which didn't help. Finally, a young man pulled over and offered me a ride, but given that he already had two motorcycles in the back of his truck, he could only take me.
He drove me to the next town, where I asked to be dropped off. Rather than drop me off, he waited while I asked around if anyone could help me to pick up my motorcycle. One elderly gentleman was working and said that I could use his pickup! Can you imagine that a stranger gave me the keys to his pickup. It was quite an experience, I must say. So, as I drove back 20 miles to get my motorcycle, the gentleman who first stopped to help me followed me. We both put the motorcycle in the back of the truck, and then I followed him another 50 miles or so and we both unloaded the motorcycle at his place. Then, he followed me back to the small town so I could return the man's truck. I didn't have much cash on me, maybe $40, but I gave it to the man for the use of his truck.
Two strangers helped rescue me from spending the night on the side of the road in ND. I don't recall their names, but when I close my eyes I can see their faces as if it were yesterday. Thank you, strangers. You may be reading this right now.

Nike
In the Greek myth, Nike is the goddess of victory and the source of inspiration for soldiers. This logo represents the wing in the famous statue of the Greek goddess. Nike’s logo was designed by Carolyn Davidson in 1971 for $35, and was registered as a trademark in 1995.
McDonald’s
The logo was designed in 1962 by Jim Schindler to resemble the archshaped(拱形的) signs on the side of the company’s then walk-up hamburger stand. Later on, the two golden arches were combined together to form the M. The McDonald’s name was added to the logo in 1968.
Apple
There are different stories behind Apple’s logo. The first logo was a reference to the religious story of Adam and Eve, in which the apple represented the fruit of the Tree of Knowledge. One year later, the second logo was designed in 1977 by Steve Jobs and Ronald Wayne, and it described Sir Isaac Newton sitting under an apple tree. This logo didn’t stay long. One year later it was replaced almost immediately by graphic designer Rob Janoff’s “rainbow apple”, a rainbow-colored silhouette(轮廓) of an apple with a bite taken out of it. And then the rainbow-colored apple was replaced by the one-colored logo in 1998. It has not been changed so far.
Mercedes Benz
The Mercedes Benz logo, which was originally created by Gottlieb Daimler in 1909, consists of a simple description of a three-pointed star that represents its rule of the land, the sea and the air. The company was founded by Gottlieb Daimler and Wilhelm Maybach. Mercedes is the name of Maybach’s elder daughter, while Benz came as a result of a combination with Benz, Cie and DMG in 1926.
Adidas
The Adidas logo, which was created by the founder of the company Adi Dassler, represents mountains, pointing towards the challenges that are seen ahead and goals that can be achieved. The logo was used for the first time in 1967.

4 . A 1400-year-old Peruvian method of diverting (转向) water could supply up to 100 million cubic meters of water—equal to 40,000 Olympic-size swimming pools' worth of water—to Lima each year, according to a new study published in Nature Sustainability. It's one example of how ancient methods could support existing modern ones in countries without enough water.
More than a billion people across the world face water shortages. Man-made reservoirs store rainwater and water overflow for use during drier times. But reservoirs are costly, require years to plan and can still fail to meet water needs.
Peru's capital, Lima, depends on water from rivers high in the Andes Mountains. It takes only a few days for water to flow down to the city. So when the dry season begins in the mountains, the water supply quickly disappears. The city suffers shortages of 43 million cubic meters during the dry season. It solves this with modern structures such as man-made reservoirs. These reservoirs are not the only solution, however. Over a thousand years ago, indigenous (本地的) people developed another way to solve water problems.
Boris Ochoa-Tocachi is a researcher at Imperial College London and lead writer of the study. He explored one of the last remaining water-harvesting systems in the small mountain community of Huamantanga, Peru. The system was developed even before the ancient Inca civilization.
The 1,400-year-old system is designed to increase the water supply during the dry season by diverting and slowing water as it travels down the mountains. This nature-based method is made of special canals that guide water from its source to a series of water bodies and hillsides. The water goes slowly into the ground, then flows downhill through the soil and reappears in water bodies near the community.
The researchers measured how much the system slowed the flow of water by injecting special dye in the highlands and noting when it reappeared in water bodies. The dyed water started to surface two weeks later and continued flowing for eight months—a huge improvement over the hours or days it would normally take.

5 . TUVALU,a tiny country in the Pacific Ocean,has asked for help as it fears it will be swallowed up by the sea.Storms and huge waves are a constant threat and none of Tuvalu’s nine little islands is more than five meters above sea level.Salt water is already entering the country’s drinking water supply,as well as damaging plants that produce fruit and vegetables.Without urgent help,the country’s days are numbered.
But Tuvalu is not the first place to face sinking into the sea.Venice,a historic city in Italy best known for its canals,has sunk about 24cm over the past 100 years.Experts say that it will have sunk another 20～50cm by 2050.A century ago,St.Mark’s Square,the lowest point in the city,flooded about nine times a year.Nowadays,it happens more than 100 times.While Venice is slowly sinking into the mud on which it stands,Tuvalu’s rising sea level is caused by global warming.
The average global temperature has increased by almost 0.5 centigrade degree over the past century,scientists expect it to rise by an extra 1～3 degrees over the next 100 years.
Warmer weather makes glaciers(冰川)melt,adding more water to the ocean.The warmer temperatures also make water expand,so it takes up more space,causing the sea level to rise.The sea level has risen about 10～25cm in the last 100 years.
The main cause of global warming is human pollution.Through burning coal,oil and gas,people have been increasing the greenhouse gases in the atmosphere,such as CO2.This adds to the power of the greenhouse effect,making the planet even warmer.
Many scientists believe that,if the warming is not stopped,there will be huge climate changes.The sea level could rise by one meter this century.
Should this come true,the sea will swallow up millions of homes and the world will be flooded with“climate refugees”looking for somewhere to live.
1. We can infer from the first paragraph that.| A．Tuvalu is in danger of moving slowly downwards into the sea |
| B．all Tuvalu’s islands are about five meters above the sea level |
| C．drinking water in Tuvalu will be destroyed |

6 . For the 17 years my life was very happy. Then the first sad thing happened. My mother became very ill, and soon she knew that she was dying. Just before she died, she asked Elizabeth and me to go to her room. She held our hands and said, “Victor and Elizabeth, my children, I’m very happy because you love each other, and because one day you’ll get married. Everyone in the family loves you, Elizabeth. Will you take my place in the family, my dear? I can die happy if you look after them when I have gone.”
My mother died and we were very sad, because we loved her dearly. Elizabeth was brave and helped us; her sweet smile gave us some happiness in the unhappy days after my mother’s death. The time came for me to go to university. I didn’t want to leave my sad family, but we all knew that I should go. It was hard to leave, too, because the parents of my good friend Henry would not let him go to university with me. So I had gone alone.
On my first day at university I met my teacher, Professor Waldman, who was one of the greatest scientists in the world. He gave a wonderful talk to all the students who were starting at the university. He ended his talk by saying, “Some of you will become the greatest scientists of tomorrow. You must study hard and discover everything that you can. This is why God made you intelligent—to help other people.”
After the professor’s talk, I thought very carefully. I remembered the storm when I was 15; I remembered how the lightning had destroyed the tree. From then on, I wanted to use electricity to help people, and I wanted to discover the secrets of life. I decided to work on these two things.
I started to work the next day. I worked very hard and soon Professor Waldman and I realized that I could learn to be a very good scientist.
The professor helped me very much, and other important scientists who were his friends helped me, too. I was interested in my work and I did not take one day’s holiday during the next two years, I did not go home, and my letters to my family were very short.
After two years, I had discovered many things and I built a scientific machine that was the best in the university. My machine would help me answer the most important question of all. How does life begin? Is it possible to put life into dead things? To answer these questions about life I had to learn first about death. I had to watch bodies from the moment when they died and the warm life left them. In the hospital and in the university, I watched the dying and the dead. Day after day, month after month, I followed death, so it was a dark and terrible time.
I built a tall mast about 150 meters high, which is higher than the tallest building in the city, to catch lightning and send the electricity down to my machine in the lab. I believed I could use that electricity to give life to things that were dead.
Then one day, the answer came to me. Suddenly I was sure that I knew the secret of life.

Ken Roberts, the man who found the rabbit, had been looking for it nearly two years. Although he had been searching in the wrong area most of the time, he found it by logic, not by luck. His success came from the fact that he had gained an important clue at the start. He had realized that the words “One of Six to Eight” under the first picture in the book connected the rabbit in some way to Katherine of Aragon, the first of Henry VIII’s six wives. Even here, however, Williams had succeeded in misleading him. Ken knew that Katherine of Aragon had died at Kimbolton in Cambrideshire in 1536 and thought that Williams had buried the rabbit there. He had been digging there for over a year before he came up with a new idea. He found out that Kit Williams had spent his childhood near Ampthill, in Bedfordshire, and thought that he must have buried the rabbit in a place he knew well, but he still could not see the connection with Katherine of Aragon, until one day he came across two stone crosses in Ampthill Park and learnt that they had been built in her honor in 1773.
Even then his search had not come to an end. It was only after he had spent several nights digging around the cross that he decided to write to Kit Williams to find out if he was wasting his time there. Williams encouraged him to continue, and on February 24th 1982, he found the treasure. It was worth £3000 in the beginning, but the excitement it had caused since its burial made it much more valuable.

8 . Xia boyu，70， the first Chinese double amputee （被截肢者） to have reached the top of Mount Qomolangma， the highest mountain in the world， Du Juan reports．
On May 14， 2018， Xia， who is the same age as the People's Republic of china， made his dream come true by reaching the top of Qomolangma （Mount Everest） seven days after leaving Base Camp on the Nepal side of the mountain．
Success didn't come easy． He had failed to reach the 8，844﹣meter peak four times before becoming one of the few double amputees to reach the top of the world．
The first climb by a Chinese team to the peak of Qomolangma was in 1960． Xia， who was born in Chongqing in 1949， was chosen by the Chinese mountaineering team in 1974． In 1975， the second mountaineering team set off． All the teammates finally reached the top， but Xia suffered bad frostbite （W1）in his legs， which had to be amputated at the knees．
"It's beyond imagination how difficult it was to accept the fact that I would suddenly become a disabled person，" Xia recalls． "I could not imagine a future of sitting in a wheelchair， perhaps forever．"
When a doctor told him that with artificial limbs he could live a normal life like anyone else， and he would even be able to do a lot of physical exercise， his hopes rose and he made up his mind to climb Qomolangma again．
To prepare for his fifth attempt（尝试）on Qomolangma， every day he got up at five in the morning and completed 90 minutes of strength training at home． On Mondays， Wednesdays and Fridays he would ride a bike to Fragrant Hills， 30 kilometers from his home， walk to the top and then ride back home． On Tuesdays， Thursdays and Saturdays， he completed 10 km of speed walking．
"Without targets， people lose' direction， "Xia says． So I will keep climbing and contributing more ways to society．"

9 . There has been a lot of publicity (宣传) recently surrounding 5G, the next generation of wireless technology for the world. But what is this technology and how might it change our lives?
What is 5G?
5G stands for fifth generation, meaning the next step in the progression of technology to replace the current 4G system. 4G was the replacement for 3G, which came after 2G, and so on. These systems are wireless computer networks. Earlier “G” systems were designed to improve mobile communication operations. Each new technology brought major improvements in speed and greatly increased network capacity. The new 5G system promises more of the same. It is expected to permit more users to do more things-at a faster rate. Higher internet speeds and larger network capacity should result in better performance for device users connected to 5G. However, technology experts say there is a major way that 5G is different than the earlier systems. It will move well beyond mobile network technology to affect many more devices and industries than other “G” versions.
When will it be available?
Before we can all use 5G, wireless companies and phone makers will have to complete and deploy (部署) a whole new system. New phones and communication equipment must be built. American wireless companies have been preparing for the new system for some time. They have been creating new network equipment and buying broadcasting space to carry 5G signals. They have built news G antennas(天线)to serve American cities and towns. Wireless providers will invest at least $275 billion n 5G-related networks in the United States, the industry group CTIA reported. The first U.S, launch of 5G is expected to happen sometime this year. Industry experts expect it will take a few more year to go nationwide. It will take even longer to reach rural areas. China is expected to launch 5G sometime in 2020, while European nations are likely to build their systems more slowly over time.
1. Which system is widely used nowadays?| A．5G. | B．2G. | C．3G | D．4G. |
| A．It will allow more users to do more things. | B．The internet speed will be much higher. |
| C．The users will spend much less money on it. | D．It will affect more devices and industries |
| A．5G system has nothing to do with phone makers. |
| B．There is much work to do before 5G comes into use. |
| C．New phones will be much smarter than those used now. |
| D．4G system will be stopped as soon as 5G comes into use. |
| A．USA→China→European nations. | B．China→USA→European nations. |
| C．USA→European nations→China. | D．European nations→China→USA. |
10 . Scientists estimate that over 500 million species have died out throughout evolution. Here is a list of 4 incredible extinct animals.
Pinta Island Tortoise
| The giant tortoise of Pinta lived on the island Pinta of the Galapagos Islands,Ecuador. By the end of the nineteenth century,most of the Pinta Island tortoises had been wiped out due to hunting. The last known individual was a male named Lonesome George who died on 24 June 2012. In his later years,he was considered the rarest animal in the world. |
Falkland Islands Wolf
| The Falkland Islands wolf was the only native land mammal of the Falkland Islands. The animal was hunted for his beautiful fur,and the shepherds(牧羊人），considering it a threat to the sheep,poisoned him. On the islands,there were no forests in which the species could take shelter,and its lack of fear towards man made it easy prey to kill. The last known individual died in the late 19th century on the western island. |
Caucasian Wisent
| The Caucasian wisent which went extinct in 1926 inhabited(栖息）the Caucasus mountains. In 1910 their numbers were estimated in the hundreds. When state authority collapsed after the First World War,the remaining population fell victim to hunters. The decline can also be contributed to an outbreak of foot-and-mouth disease that was introduced with cattle. |
Javan Tiger
| The Javan tiger is an extinct subspecies of the tiger that was native to the Indonesian island of Java. Very little data was gathered about their behavior before they were driven to extinction. The reduction of its two main prey species,and the modification of its habitat led to the extinction of the subspecies in the 1980s. |
1. According to the passage,which shows the correct order of the animals' extinction?
① Pinta Island tortoise ② Falkland Islands wolf
③ Caucasian wisent ④Javan tiger
| A．②③①④ | B．②③④① |
| C．③②④① | D．③④②① |
