It was a really eye-opening trip. First, we saw a life-size model of a blue whale in the main hall. It was 30 meters long! The guide told us an adult blue whale can weigh up to 180 tons, as heavy as 30 elephants. It is the largest animal that has ever lived on Earth. Next, we went to the plant exhibition area. The most interesting plant there was the Venus flytrap. The guide showed us a video of the plant catching a fly. When the fly stepped on its leaf, the leaf closed so quickly that the fly had no time to fly away. We also learned about cacti (仙人掌) in the desert area. Cacti store water in their thick stems (茎) so they can live for months without rain. Before we left, we watched a short video about endangered animals. The guide told us that hundreds of kinds of animals and plants are disappearing every year because of human activities. I felt a little sad, but I also learned that everyone can do small things to help protect nature. This trip let me see how amazing the natural world is. I decided to join the school nature club to learn more about plants and animals. ( )1. Who did the writer go to the Natural History Museum with? A. His/Her parents B. His/Her classmates and biology teacher C. His/Her pen pal D. His/Her grandparents ( )2. How heavy can an adult blue whale be? A. 18 tons B. 80 tons C. 180 tons D. 800 tons ( )3. What can the Venus flytrap do, according to the passage? A. It can change its color to hide. B. It can catch and eat small insects. C. It can grow 1 meter a day. D. It can live in deserts without water. ( )4. What does the underlined word "store" in Paragraph 3 mean in Chinese? A. 储存 B. 消耗 C. 制造 D. 蒸发 ( )5. What did the writer decide to do after the trip? A. To keep a cactus as a pet. B. To study all plants and animals. C. To join the school nature club. D. To work in the museum in the future. Passage B We asked three students to talk about the most amazing plant or animal they know. Zhang Na: I think the most amazing animal is the giraffe. Giraffes are the tallest animals on land—adult giraffes can be 6 meters tall. The most interesting thing is that a giraffe's neck is more than 2 meters long, but it has the same number of neck bones as a human being! Giraffes' long legs help them run very fast to run away from lions. Liu Tao: For me, chameleons are the most amazing animals. Most people know chameleons can change their skin color to match the environment, so their enemies cannot find them easily. But do you know their eyes can look in two different directions at the same time? That means they can look for food and watch for danger at the same time! Wang Hao: I think ants are the most amazing creatures. They are so small, but they can carry things 50 times heavier than their own body weight. They also work in groups all the time: when they find food, they will leave a special smell to tell other ants, and they work together to carry the food back home. They are really hard-working. ( )6. How long is a giraffe's neck, according to Zhang Na? A. About 1 meter. B. More than 2 meters. C. 6 meters. D. The same as a human's neck. ( )7. Why can chameleons keep themselves safe? A. Because they can run very fast. B. Because they can change colors to hide. C. Because they are bigger than their enemies. D. Because they can fly away quickly. ( )8. How much weight can an ant carry? A. Things as heavy as its own body. B. Things 5 times heavier than its body. C. Things 15 times heavier than its body. D. Things 50 times heavier than its body. ( )9. Which of the following is TRUE? A. Giraffes have more neck bones than human beings. B. Chameleons' eyes can look in two directions at the same time. C. Ants usually look for food alone. D. All three students talked about amazing plants. ( )10. What is the main idea of the passage? A. How to protect amazing animals. B. Facts about animals living in the rainforest. C. Three students' favorite amazing animals. D. Why students should learn biology well. 四、情景对话 七选五（共5小题，每小题2分，满分10分） 根据对话内容，从方框内的选项中选出能填入空白处的最佳选项，有两个为多余选项，作答时请将答案写在横线上。 A: Hi Li Wei!
