参考答案
【语篇导读】面对塑料袋被禁止的政策,塑料袋生产商雇用一些科学家来证明塑料袋对环境的影响不像人们想象中的那样糟,同时分析了塑料袋、纸袋以及可循环利用的环保袋各自的利弊。
1.D 细节理解题。根据第二段最后一句中的 plastic bag makers are hiring scientists like Stein t make the case that their prducts are nt as bad fr the planet as mst peple assume 可知,塑料袋生产商雇用史蒂文·斯坦是为了向人们证明塑料袋不像人们想象中的那样对地球有害,即为了支持塑料袋的使用。
2.A 词义猜测题。根据画线词前的 S many end up in tree branches r alng highways that a grwing number f cities d nt allw them at checkuts.The bags are hibited in sme 90 cities in Califrnia，including Ls Angeles.可知，很多地方已禁止使用塑料袋。由此可推知，画线词应指的是对塑料袋的禁令。
【微技能】根据上下文信息判断指代内容
任何一篇文章中的句子在内容上都不是绝对孤立的，都与句子所在的段落及整篇文章有关。在做推断词语指代的内容这类题时，学生应利用上下文提供的情景和线索，进行符合逻辑的综合分析并依此来推测其所指代的内容。
本题中，根据画线词前的 these 一词可知，headwinds指的是前文出现过的内容，所以我们可以据此锁定解题依据的范围，即这一段的前三句。再细读这三句话可知，加利福尼亚州的90个城市都禁止使用塑料袋。由此可判断 these headwinds 指代上文提到的“禁止使用塑料袋”，后文也介绍了针对这样的情况厂家想出的对策。因此 Bans n plastic bags正确。
3.D 细节理解题。根据第四段第三句 Hwever，lnger lasting reusable bags ften require mre energy t make 可知，更加耐用的环保袋在生产过程中需要耗费更多的能源。
4.A 主旨大意题。通读全文内容可知，本文主要介绍了塑料袋、纸袋以及可循环利用的环保袋各自的利弊，故A项为最适合本文的标题。
