They are also a symbol of good luck here. The elephant is our national animal. On 13 March, we celebrate Thai Elephant Day. Elephants look very different from other animals. They are huge. They have large ears and long trunks. They can pick up and carry heavy things with their trunks. Elephants are like us in some ways. They are very playful and love to play in the water. They are great swimmers. They are also clever. For example, they can remember one another and places with food and water after many years. Elephants are very kind too. They look after other elephants when they don’t feel well. The big elephants also help the baby ones. Elephants are an important part of Thai life and culture. However, they are in danger. They live in forests, but people cut down too many trees. People also kill elephants for their ivory. Let’s save the forests and not buy things made of ivory. Every elephant counts. 16．Why does Malee love elephants? 17．What can elephants do with their trunks? 18．How are elephants like us? 19．Why are elephants in danger? 20．What should we do to save elephants? 四、选词填空 beauty   watch   dangerous   scare   they   symbol   make   kill   real   tiger Which animal do you think is “the king of the animals”, the elephant, the lion or the tiger? I think the tiger is “the king of the animals”. Because you can find some black lines (线) on the 21 forehead (前额). The lines look like Chinese word “Wang”. It’s one of the 22 of the king in Chinese. Tigers are dangerous animals. They like eating meat. They have yellow and 23 fur with black lines. Tigers can run very fast. People like 24 them in the zoo, but they usually feel 25 when tigers walk to them. Most people think tigers are dangerous, but they don’t know tigers are in 26 now. People cut down many trees, so tigers are losing 27 homes. There are only about 70 Siberian tigers in China. Lots of people want 28 them for their fur. We must save tigers and not buy things 29 of their fur. They 30 need our help. 1 学科网（北京）股份有限公司 $$ Unit 1 Section B（ 1a-1d） (分层练习） 一、单项选择 1．The elephant is ________ Thailand’s ________.
