We Can’t Live Without Bees
Imagine / 'm d n/ you go to the supermarket in your area, but there are almost no fruits, vegetables, honey/'h ni/, milk, eggs, or chocolate. How would you feel Disappointed/d s 'p nt d/ Angry Sad At this moment you realize people, plants, and animals are all connected /k 'nekt d/. We need each other to live, and bees are one of the best examples of this connection /k 'nek n/.
Bees are very hard-working animals, and their greatest work is pollination /p l 'ne n/ . On one trip, they often visit 50 to 100 flowers. As they fly from one flower to another, they take pollen/'p l n/ with them. This action /' k n/ helps plants grow. In fact, without /w ' a t/ their work, about 80 per cent /p 'sent/ of the plants in the world cannot grow. For this reason, m any scientists believe that bees are the most important animals on this planet /'pl n t/.

Bees are also one of the most interesting animals in the world. For example, they work hard together to make their homes. In order to store /st (r)/ honey, they create honeycombs /'h nik m/. Another interesting thing about bees is how they communicate /k 'mju n ke t/. When a bee finds new food, it uses a dance to tell the others where and how far away the food is.

范文参考
Good morning, ladies and gentlemen. I’m glad to stand here to give you a speech. Today, my topic is “Let’s do something to protect the blue whales”.
Blue whales are the largest and the heaviest mammals in the world and they live in the ocean. They feed on some of the tiniest animals in the ocean. Blue whales are in danger now.
Firstly, they have less food to eat because the water is polluted. Secondly, they have fewer babies due to the bad weather conditions. Thirdly, people kill them for food, which makes it hard for them to survive.
In my opinion, our government should stop people from killing them and make plans to protect them. Besides, we can do research on sewage management. What’s more, we can raise money to make signs to tell people about the importance of protecting blue whales. At last, we can also collect litter to help protect their living environment.
