文章主题一般会在开头部分就有所显露，但是最好还是在听完全部录音之后再选正确答案。开头部分说的是环境和循环再利用的话题，后面的部分也还是围绕这个内容展开的，可以确定这就是文章的主题。(A)选项中说的产品设计和(C)选项中说的瑞典的垃圾只是文章中提到的一部分，不能说是文章的主题。

听录音的时候要把注意力放在题目的中心the Swedishes，tax on black rubbish bags上。在第2句话中以举例的方式提到了瑞典这个国家，后面的内容就是正确答案的线索not just to throw things straight in the bin和reduce the rubbish。

【答案解析】中级问题
题目中使用的improve，the situation等词就是在The situation has improved in recent years，mainly because of这句话中集中出现的，所以我们很容易就可以找到应该留意的部分。Tighter controls and higher standers最终都可以被称为law。
