(单选题)
What is the first paragraph mainly about?
A.Plastics are never highly recyclable.
B.Plastics are widely used in our lives.
C.Plastics have both advantages and disadvantages.
D.Plastics take hundreds of years to be broken down.
参考答案:C
参考解析:
概括归纳题。根据第一段第二至五句“Things made of plastics can be very strong and last a long time…And very few kinds are highly recyclable.”可知,塑料结实耐用,更易成型;需要上百年才能降解,且几乎不能循环利用;所以本段既讲了塑料的优点也讲了缺点。故选C。
