One possible version:
Come and join us, clear your plate!
Boys and girls,
Good morning, everyone. I am Lily. I am in Class 28, Grade Nine. I study in No.12 Middle School. It’s my honor to give a speech in front of you.
Do you like food? What’s your favorite food? Do you know how the farmers plant rice and corn?
In our daily life, we can’t live without food. Food is very important, isn’t it? But I am sorry to see many people waste food. Some people throw away the rest food into the dustbin. Why don’t they plan to prepare suitable food. When you go to have dinner with your friends in the restaurant, have you ever ordered too much food?
My dear friends, we know many people in South Africa are lack of food. If there is bad weather, rice can’t grow. So we must stop wasting food. From now on, come and join “clear your plate” compaign. When we have dinner with our family in the restaurant, we never order too much food. If there is some food left, pack it home. Don’t put it off, take actions!
That’s all. Thank you!
