2019外研社选择性必修一第五单元课文(中英互译)Unit 5 Understanding ideas
A Journey of Discovery发现之旅1 The captain of the ship, the Beagle, wanted someone who would “profit by the opportunity of visiting distant countries yet little known”. The person who answered the call was not the captain’s first choice. It was a young man who had left medical school without completing his degree. What’s more, he had recently received a letter from his father predicting that he would be “a disgrace to yourself and all your family”. Despite all this, his adventures on this ship would lead to one of the most important scientific discoveries of all time.贝格尔号的船长想要招募这样一名船员，这名船员将能“借此机会访问遥远而鲜为人知的国家并从中受益”。
然而来应聘的人并不是船长心中的理想人选。
这个年轻人从医学院肄业，并且在他刚收到父亲的来信，信中预言他将会成为“自己和全家人的耻辱”。
尽管如此，他的这次乘船探险之旅将带来有史以来最重要的一项科学发现。
2 The young man in question, Charles Darwin, was a geologist and naturalist, fascinated by rocks, plants and animals. He left England on the ship, the Beagle, in 1831. The journey gave him the chance to study various living things in their natural environments. After Darwin had spent some time in South America, his room on the ship was crowded with samples of the plants and animals he had collected. As he studied these, he asked himself the question: how did different species come to exist?我们提到的这个年轻人就是地质学家和博物学家查尔斯·达尔文，他对岩石和动植物有着浓厚的兴趣。

Birds may fly from one part of the world to another, perhaps stopping at feeding grounds on the way. Whales and turtles travel through huge areas of the ocean. A report says that changes in anyone of the places where these animals stay can cause serious problems. "Obviously these animals have developed their traveling ways over thousands of years. But climate change is almost certain to be extreme over the next 25 to 50 years. And it is impossible for these animals to change their habits fast enough, " said the report writer Dr. Robert Hepworth.Turtles are e hit hardest by rising temperatures. Scientists s have found that at higher temperatures, turtles have far more female eggs than male ones. In parts of Malaysia, turtles are only giving birth to female babies. And some turtles are more likely to develop cancer as the waters get warmer.With birds, the main problem is the harm to important areas at the end of their travels or at resting places along the way. About one-fifth of migratory birds are now in danger because of these changes, including the rising sea level, land loss and morestrong storms.Some other animals are now in great danger. For example, the North Atlantic right whale is losing their food because of the changing ocean flow; The white-nosed dolphin is out-competed（淘汰）by other kinds in warmer waters.The report is not all bad news. Even with the temperature changing, protecting the environment can still help migratory animals return. "We need governments to start taking action all over the world. The clock is ticking. We should make full use of every minute," said Dr. Hepworth. And now some projects are already working! Whales are changing their feeding habits, finding new feeding grounds and new foods to eat.4. Why does this rising temperature mean the end of some migratory animals?A. They stop moving through several environments.B. They can't adapt to the changes during their travelling.C. Their t travelling habits will be changed fast enough.D. They keep flying from one part of the world to another.5. What is the result of the warming according to the passage?A. The North Atlantic right whale may find new food.B. Some turtles may develop cancer with the warm waters.C. 1/5 of migratory birds change their feeding habits.D. The white-nosed dolphin may have only female babies.6. What does the underlined sentence "The clock is ticking. " mean?A. It takes time to achieve the project.B.

If you exercise out of doors, your body will learn to breathe more deeply, allowing even more oxygen to get to your muscles（肌肉）and your brain.Recently, people have begun studying the connection between the natural world and healing（治愈）. 3 In these places patients can go to be near nature during their recovery. It turns out that just looking at green, growing things can reduce stress, lower blood pressure, and put people into a better mood（情绪）. Greenery is good for us. Hospital patients who see tree branches out their window are likely to recover at a faster rate than patients who see buildings or sky instead. 4 It gives us a great feeling of peace.5 While the sun's rays can age and harm our skin, they also give us beneficial vitamin D. To make sure you get enough vitamin D-but still protect your skin-put on sunscreen right as you head outside. It takes sunscreen about fifteen minutes to start working, and that's plenty of time for your skin to absorb a day's worth of vitamin D.A. Fresh air cleans our lungs.B. So what are you waiting for?C.

■ Read the passage and finish the tasks.(1)As we all know, many animals migrate. Some migrating animals move to a place which has a better temperature. Some go to find food or water. During the trip, they face more challenges than we can imagine.One challenge is distance. Some migrating animals take very long trip. For example, one great white shark swam about 20,000 kilometers in nine months.Another challenge is to find enough food and water during their journeys. For example, each Mali elephant needs more 200 liters (公升)of water each day. To get this, they need to go from one waterhole to another.In addition, migrating animas have to avoid other animals that want to eat them. For example, the zebra has to stay away from the lion. Traveling as a group helps keep them safe. By working as a group, migrating animals can survive some of the world's most wonderful journeys.1) According to the passage, which animal migrate?2) Do you know some other animals that migrate?

Unit5 Understanding ideas提升测评I.阅读理解（2019山东济南外国语学校高一下月考）According to the new research from the University of Cambridge in England, sheep are able to recognize human faces from photographs.The farm animals, who are social and have large brains, were previously known to be able to recognize one another, as well as familiar humans. However, their ability to recognize human faces from photos alone is novel.The recent study, the results of which were published in the journal Royal Society showed the woolly creatures could be trained to recognize still images of human faces, including those of the former President Barack Obama and actress Emma Watson.Initially, the sheep were trained to approach certain images by being given food rewards. Later, they were able to recognize the image for which they had been rewarded. The sheep could even recognize images of faces shown at an angle, though their ability to do so declined by about 15 percent—the same rate by which a human’s ability to perform the same task declines.“Anyone who has spent time working with sheep will know that they are intelligent and individual animal are able to recognize their handlers,” said Professor Jenny Morton，who led the Cambridge study. “We’ve shown with our study that sheep have advanced face-recognition abilities, comparable with those of humans and monkeys.”Recognizing faces is one of the most important social skills for human beings, and some disorders of the brain, including Huntington’s disease, which affect this ability.“Sheep are long-lived and have brains that are similar in size and complexity to those of some monkeys. That means they can be useful models to help us understand disorders of the brain, such as Huntington’s disease, which develops over a long time and affects cognitive abilities. Our study gives us another way to monitor how these abilities change,” said Morton.1. According to the new research, what’s unusual about sheep?A. They have large brains.B. They can recognize their owners.C. They can tell animals from humans.D. They can recognize human faces from photographs.2. What can be inferred from the passage?A. Sheep have a higher face-recognition ability than monkeys.B. The new discovery is beneficial to the study how the cognitive ability changes.C. The sheep’s face-recognition ability says the same when photos are shown at an angle.D. The sheep’s face-recognition ability may prevent some disorders of the brain.3. What’s the best title of the passage?A. A New Discovery about SheepB. How Do Sheep Recognize Each Other?C. A Wonderful ScientistD.
