【解析】听力原文：

Good morning, this is Helen Green with this edition of Morning Hours on the air. Now if you've got nothing to do today, why not go to the ease part of the city and get digging. That's the message from No. 1 Senior High School, which is organizing a tree planting event near East Mountain.

No. 1 Senior High School is a member of the environmental group of the city. In order to improve the environmental education of its students and get more people organized, the school is planning to plant a total of 1,400 trees paid by the government over the next few days.

They are hoping to plant half of them today and they are looking for volunteers to come along and help. No experience is neccessary, as there will be experts to give directions and the equipment will be provided. But if you have any tree planting tools, please do bring them along in case of a lot of people come and want to start digging at the same time.

Every one is welcome to come along anytime between 10 and 4 o'clock. Because you will be working in the mountains, I don't think you need my advice of what sort of shoes or clothes you have to wear. And of course, gloves will be essential to protect your hands if you're actually doing the digging. So it could be really a nice day out for all the families. Enjoy your day.
