People usually think sharks live alone, but a new study suggests that bull sharks have friends they like to spend time with. Scientists watched 184 sharks over six years. The sharks were fed together inside a protected area. Researchers could go deep down and watch them. The team recorded their actions, such as sharks leading and following each other and how close together the sharks swam. They found that both male (雄性的) and female (雌性的) bull sharks like to play with females, but males form more social relationships. This might be because males are smaller than females, so having more friends protects them from larger sea animals. The researchers said that like other animals, bull sharks might learn new skills, find food and stay safe from enemies by social connections. “As humans, we build different kinds of social relationships. And these sharks are doing similar things,” said Natasha Marosi, who led the research. The scientists said understanding bull sharks’ actions can teach us more about how they live together and move around, which can help with shark protection. 1．What does the new study find about bull sharks? A．They live alone. B．They like humans. C．They have friends. D．They feed each other. 2．What might be the reason for male sharks to form more social relationships? A．They need protection. B．They want to be leaders. C．They need more areas. D．They want to meet females. 3．What is the last paragraph mainly about? A．The meaning of the study. B．The cause of human action. C．The advantage of social life. D．The way of shark protection. 4. How does the author develop the passage? A. By following the time order B. By telling a story C. By giving examples D. By comparing facts B Scientists are creating robots that can be used in many different areas of life. Recently a new kind of robot which looks like a penguin has been developed. The penguin robot helps scientists get closer to emperor penguins (帝企鹅) to know more about their behaviour. Emperor penguins are famous as shy animals. They usually feel nervous and run away when scientists go towards them. This will cause problems to their hearts. To solve it, a team of scientists created a remote control vehicle (遥控车). This vehicle allowed the scientists to study the penguins from over 200 metres away. It could move up to the penguins slowly and quietly without making them run away. It was also used to help make the documentary March of the Penguins. The scientists still wanted to watch emperor penguins much closer. After trying many times, they developed their latest robot which was like a little grey penguin. It had four black wheels, two black arms and a black-and-white painted face. The wheels were prepared for the robot to walk on the thick snow easily. This new robot didn’t scare (惊吓) the penguins. They even sang songs to welcome the robot and listened for a response. But the penguins were very unhappy when there was no answer. The scientists didn’t programme (编写程序) the penguin robot to make a sound. Next time they will have the robot sing songs. Thanks to the robots, scientists could do much more research on emperor penguins. 5．Why was the penguin robot developed? A．To know about scientists’ heart problems. B．To help scientists walk on the thick snow. C．To learn about emperor penguins’ behaviour. D．To help emperor penguins look for more food. 6．How do emperor penguins feel when scientists go towards them? A．Sad. B．Angry. C．Excited. D．Nervous. 7．What does the word “response” in Paragraph 3 mean? A．Plan. B．Answer. C．Lesson. D．Reason. 8．What will the penguin robot do next time according to the passage? A．Sing songs. B．Swim in the sea. C．Take photos. D．Dance on the snow. 9．What is the passage mainly about? A．Penguins in the film. B．Penguins in the zoo. C．Robots for daily housework. D．Robots for studying penguins. 八、请阅读下面语篇，根据其内容，从所给的选项中选出能填入空白处的最佳选项，使其意思通顺，并在答题卡上将该项涂黑。选项中有一项为多余选项。 Imagine you have just cleaned your classroom. Then a strict teacher in school walks in, looks around, and gives you a big smile. 1 But this time the testers are birds. In recent years, groups of rare (稀有的) birds like black storks and egrets have been seen along the Fenhe River. 2 These birds are very picky: they only live near clean water. Their arrival makes the river full of life. Things were quite different in the past. There were few rare birds. 3 Because the river was polluted seriously. Then the government started a plan to bring the river back to life. Workers spared no effort to turn dirty water into clean water. 4 These wetlands helped clean the water. The water quality has improved a lot. 5 There are more plants growing in the wetlands. More and more birds choose the Fenhe River as their winter home. When people take care of nature, nature gives back. The balance between humans and nature has become a reality in Shanxi. A．Why was that? B．They rest along the river banks playing happily. C．The results of people’s hard work are easy to see. D．The Fenhe River is the mother river of Shanxi Province. E．That is exactly what is happening along the Fenhe River. F．What’s more, they cleaned and added wetlands along the river. 九、短文填空 阅读短文，在空白处填入一个适当的单词或用括号内所给词的正确形式填空，使短文通顺、连贯。 I’ve photographed Africa’s wild places for more than 30 years.
