最近雅思口语出现了一个新话题trees，这让很多烤鸭们不知所措，在考场上回答的不是很理想。因此，环球教育老师为考生们解读有关“树”的话题，究竟可以从哪些角度去进行扩展。
   在Part1中考官可能会问到一下几个问题：
   Do you like trees？Why？
   What kind of trees do you like best？
   Do people like to protect trees? Why？
   What is the effect of trees?
   Is it comfortable to live in a place with lots of trees?
   ……
   
   针对于是否喜欢树，相信大多数考生的答案都是喜欢。为什么喜欢？因为树能够改善环境，因为在夏天树可以为我们遮阴，因为有些树很漂亮，可以作为景观进行观赏等等。
   你喜欢哪种树？相信很多考生连树的名称都说不出几个吧，建议在考前好好准备一下，利用网络资源扩充一下这方面的词汇。
   下面是对于树的优缺点的列举：
  The effect/benefit of trees
   1 They can make a city, as a whole, a bit less windy or a bit more windy, if that’s what you want.
   2 They can make it a bit cooler if it’s a hot summer day in an Australia city, or they can make it a bit more humid if it’s a dry inland city.
   3 Trees can make the local area more shady, cooler, more humid and much less windy.
   4 In fact trees and planting of various kinds can be used to make city streets actually less dangerous in particular areas.------Trees help to filter the wind.
   5 By planting a belt of trees at the side of the road, you can make things a little quieter.
   
   Negative effects
   1 Although trees can significantly improve the local climate, they do however take up a lot of space.
   2 There are root system to consider and branches block the window and so on.
