Advantages of Organic Farming
In my eyes, compared to chemical farming, organic farming enjoys its overwhelming superiority. The reasons are as follows.
Firstly, organic food is healthier and safer as in organic farming, poisonous chemicals like pesticides are forbidden from being used on crops. Furthermore, organic farming is environmentally friendly. For instance, organic farmers use natural waste from animals as fertilizer, which is harmless to the environment. Lastly, farmers can increase their income buy selling organic food at high price. As people tend to pursue a green life, they are more likely to buy organic fruit and vegetables despite the high prices.
All in all, with incomparable advantages, therefore, organic farming is expected to benefit more people in the future.

3.你的看法
正反观点+理由
自己观点及理由
Recently our class had a heated discussion about
whether we should help strangers. Opinions are divided
on this issue.
Some people are in favor of it, saying that
helping others is a traditional virtue, which can bring love
and warmth to the people in need. Additionally,
helping others means helping us, because everyone
needs help. However,others have the opposite opinion.
They argue that helping others can sometimes bring us
trouble. What's worse, maybe we are misunderstood
by some people. 　
In my opinion, we should try our best to help others
when they are in need of help, but first we should avoid
getting into trouble．
