改错:
What can we do to fight pollution?First,we must put【删掉the】 rubbish into rubbish bins.【Sencond拼错了,是second】,we mustn't use too many plastic bags.【改Then为Third(这里用then不适合)】,we must plant more trees.We must 【改“take a bus or ride a bike or walk to school”为get to school either by bus,bike or on foot】.【改And为In addition或Furthermore】 we must 【改close为turn off】all the lights and fans when we leave a room.We must close all 【删掉the】 windows when we use 【改the 为an】air-conditioner.
注:"Second,we mustn't use too many plastic bags"这句话虽然没有语法错误.但是你的题目是“What can we do to fight pollution".你给的是”我们不该做什么“的答案,但是给一个”我们该做什么的“肯定句式更好些.因此,建议把这一句话改为"Second,we must reduce the amount of plastic bags we use." (我们应当减少用塑料袋的数量).
fight后面against可加可不加.
