三、必背文段
Without doubt, organic（有机的） food, just as anything else, comes with the pros and
cons（利弊,优缺） On the one hand, the world’s population is under great pressure now, which
makes it clearly impossible for organic food to be available to everyone. But on the other hand,
organic food is healthier and more eco-friendly. Only by ingesting[ɪnˈdʒest]（摄入） organic
food can we avoid many health risks and side effect(副作用） of non-organic food. More land
around the world is being dedicated to organic farming. As for the problem of population, I’m sure
资料整理【淘宝店铺：向阳百分百】that it will be solved as technology develops.
I have a dream that one day all of us will be able to get organic food. When that day comes,
we will be able to live a truly healthy life free from worries and risks. Let’s support organic food.
