In the video, a wolf called Green 1.  　 　(help) his keeper Li Weiyi out of a frozen lake. It quickly spread online and got millions 2.  　 　 likes.  The real story happened in 2010. Li was a 3.  　 　(paint) and when she was painting on the grassland, she found a weak baby wolf. The little wolf’s parents died 4.   　 of illegal hunting. Li decided 5.  　 　　(look) after him. She named the cub “Green” and raised him in Chengdu, but soon she realized that wild creatures belong to the wilderness rather than 6.  　 　(city). As a result, she teamed up with director Yi Feng to take Green back to the grassland for wildness training. After months of tough work, Green became the first human-bred wolf 7.  　 　　(success) accepted by a wild wolf pack worldwide.  Now the number of 8.  　 　(wolf) is becoming smaller.

Scientific research shows that they are born with certain unusual abilities for direction. A certain kind of ants, for example, can count their steps to avoid getting lost. They can go as far as 110 metres and bring food home. These ants live in the open desert, so they have nothing to guide them along the way. It’s like someone walking six kilometres through a dark forest. Some fish have an unbelievable sense of smell. They can smell even a single drop of their home water in a large sea area. Some seabirds have a similar ability. They can make a map of their flying area. Some animals can sense the earth’s magnetic field(磁场), while humans can’t. This magnetic field guides a certain kind of fish when they swim a long way to a place and then back. How can this kind of fish do that? It is still a mystery. Scientists have had no good answers yet. However, animals with such unusual abilities still have difficulty dealing with environmental changes caused by human activities. For example, many birds depend on stars for direction, but they get lost easily at night when city lights are kept on all night. To solve this problem, we can simply turn off some lights at night. Clearly, one small act by humans may mean a lot to animals. （　　）1. How can a certain kind of ants find their way? A. By imagining the way. B. By counting their steps. C. By bringing food together. D. By walking through a forest. （　　）2. What does the underlined word “mystery” in Paragraph 3 probably mean? A. Secret. B. Choice. C. Reason. D. Feeling. （　　）3. Which can be the best title for the passage? A. Birds’ Sense of Light B. Fish’s Sense of Smell C. Animals’ Sense of Direction D.

You may hear that groundhogs can predict(预测) the end of winter. Some of the sayings, like “If a cat sits with its back to the fire, hard weather can be expected.”, may sound unbelievable, but some may be true. Many animals do have stronger senses than humans. Do animals tell us when a storm is coming? Birds react to the drop in air pressure(气压) before a storm by flying low. Insects stay close to the ground and wolves howl because their ears can sense the pressure change. A good rule is that when animals act strangely, you probably should be careful with the environment around you. Do you know that the sound of crickets’ chirping(鸣叫) can tell you how hot the day is? Crickets are cold-blooded, so when the temperature in the air changes, the cricket’s body temperature changes with it. As the temperature rises, the cricket’s metabolism(新陈代谢) increases. When the heat rises, crickets chirp. To get the temperature in degrees Fahrenheit(℉), count the number of chirps in 14 seconds, and add 40. Do you have a tried-and-true weather animal that predicts the weather? 根据短文内容回答问题,每题答案不超过6个词。 1. Why can some animals know the weather changes? 　 　 　 　 　 2. What do birds do before the storm? 　 　 　 　 　 3. When should we be careful with the environment? 　 　 　 　 　 4. What can crickets’ chirps tell us? 　 　 　 　 　 5.

In recent years, scientists have done research on the feelings of cows, frogs and pandas.  　▲　 It says that humans can tell whether a chicken is happy or sad by listening to its calls.  ② The researchers put a bowl behind a door. Inside the bowl, sometimes, there was something chickens love to eat, such as rice or insects. Sometimes, there was nothing. When the chickens saw food behind the door, they seemed happy and produced fast and loud sounds, known as food calls. When there wasn’t food, the chickens made low and long noises to express disappointment. The researchers recorded all these sounds and studied their waves. ③ Then the researchers chose 16 recordings of such chicken noises. Half were from the chickens seeing the food and half were from the chickens finding no food. The recordings were played to 194 volunteers. 69% of the volunteers correctly understood whether the chickens were feeling happy or not, and some of them even had no experience of taking care of chickens. ④ The result shows that humans have the natural ability to understand the feelings of chickens. Hopefully, this finding can bring about new technology to help with chicken-raising, a big industry in many countries. Some scientists are already working on a smart computer program that can identify chickens’ feelings. This is good news for farmers who want to make the birds happier and healthier. （　　）1.

In the video, a wolf called Green 1.  　helped　(help) his keeper Li Weiyi out of a frozen lake. It quickly spread online and got millions 2.  　of　 likes.  The real story happened in 2010. Li was a 3.  　painter　(paint) and when she was painting on the grassland, she found a weak baby wolf. The little wolf’s parents died 4.  　because　 of illegal hunting. Li decided 5.  　to look　(look) after him. She named the cub “Green” and raised him in Chengdu, but soon she realized that wild creatures belong to the wilderness rather than 6.  　cities　(city). As a result, she teamed up with director Yi Feng to take Green back to the grassland for wildness training. After months of tough work, Green became the first human-bred wolf 7.  　successfully　(success) accepted by a wild wolf pack worldwide.  Now the number of 8.  　wolves　(wolf) is becoming smaller. Wolves are protected animals in our country, but we still need to do 9.  　more　(much) to protect them. The hot documentary tells us that wild animals are our friends. It asks us to love nature and build a better world for all living things. It is said that 10.  　the　 wolf king Green has passed away, but so far there has been no exact news.  五、阅读理解。 Some animals can easily find their way home after a long journey. How do they make it? Scientific research shows that they are born with certain unusual abilities for direction. A certain kind of ants, for example, can count their steps to avoid getting lost. They can go as far as 110 metres and bring food home. These ants live in the open desert, so they have nothing to guide them along the way. It’s like someone walking six kilometres through a dark forest. Some fish have an unbelievable sense of smell. They can smell even a single drop of their home water in a large sea area. Some seabirds have a similar ability. They can make a map of their flying area. Some animals can sense the earth’s magnetic field(磁场), while humans can’t. This magnetic field guides a certain kind of fish when they swim a long way to a place and then back. How can this kind of fish do that? It is still a mystery. Scientists have had no good answers yet. However, animals with such unusual abilities still have difficulty dealing with environmental changes caused by human activities. For example, many birds depend on stars for direction, but they get lost easily at night when city lights are kept on all night. To solve this problem, we can simply turn off some lights at night. Clearly, one small act by humans may mean a lot to animals. （　B　）1. How can a certain kind of ants find their way? A. By imagining the way. B. By counting their steps. C. By bringing food together. D. By walking through a forest. （　A　）2. What does the underlined word “mystery” in Paragraph 3 probably mean? A. Secret. B. Choice. C. Reason. D. Feeling. （　C　）3.

You may hear that groundhogs can predict(预测) the end of winter. Some of the sayings, like “If a cat sits with its back to the fire, hard weather can be expected.”, may sound unbelievable, but some may be true. Many animals do have stronger senses than humans. Do animals tell us when a storm is coming? Birds react to the drop in air pressure(气压) before a storm by flying low. Insects stay close to the ground and wolves howl because their ears can sense the pressure change. A good rule is that when animals act strangely, you probably should be careful with the environment around you. Do you know that the sound of crickets’ chirping(鸣叫) can tell you how hot the day is? Crickets are cold-blooded, so when the temperature in the air changes, the cricket’s body temperature changes with it. As the temperature rises, the cricket’s metabolism(新陈代谢) increases. When the heat rises, crickets chirp. To get the temperature in degrees Fahrenheit(℉), count the number of chirps in 14 seconds, and add 40. Do you have a tried-and-true weather animal that predicts the weather? 根据短文内容回答问题,每题答案不超过6个词。 1. Why can some animals know the weather changes? Because they have stronger senses. 2. What do birds do before the storm? They fly low. 3. When should we be careful with the environment? When animals act strangely. 4. What can crickets’ chirps tell us? How hot the day is. 5.

In recent years, scientists have done research on the feelings of cows, frogs and pandas.  　▲　 It says that humans can tell whether a chicken is happy or sad by listening to its calls.  ② The researchers put a bowl behind a door. Inside the bowl, sometimes, there was something chickens love to eat, such as rice or insects. Sometimes, there was nothing. When the chickens saw food behind the door, they seemed happy and produced fast and loud sounds, known as food calls. When there wasn’t food, the chickens made low and long noises to express disappointment. The researchers recorded all these sounds and studied their waves. ③ Then the researchers chose 16 recordings of such chicken noises. Half were from the chickens seeing the food and half were from the chickens finding no food. The recordings were played to 194 volunteers. 69% of the volunteers correctly understood whether the chickens were feeling happy or not, and some of them even had no experience of taking care of chickens. ④ The result shows that humans have the natural ability to understand the feelings of chickens. Hopefully, this finding can bring about new technology to help with chicken-raising, a big industry in many countries. Some scientists are already working on a smart computer program that can identify chickens’ feelings. This is good news for farmers who want to make the birds happier and healthier. （　D　）1. Which of the following can be put in “ 　▲　” in Paragraph 1?  A. Humans may not like animals. B. Scientists know nothing about it. C. Nobody knows why this happens. D. A new study adds chickens to the list. （　D　）2. Which is most probably the sound wave of a happy call by a chicken? （　B　）3. What is the best title for the passage? A. Chickens’ Food Calls B. Happy Chickens, Sad Chickens C. Farmers’ Best Choice D. Smart Farmers, Healthy Farmers 1 学科网（北京）股份有限公司 $
