參考答案
【語篇導讀】面對塑料袋被禁止的政策,塑料袋生產商雇用一些科學家來證明塑料袋對環(huán)境的影響不像人們想象中的那樣糟,同時分析了塑料袋、紙袋以及可循環(huán)利用的環(huán)保袋各自的利弊。
1.D 細節(jié)理解題。根據(jù)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,塑料袋生產商雇用史蒂文·斯坦是為了向人們證明塑料袋不像人們想象中的那樣對地球有害,即為了支持塑料袋的使用。
2.A 詞義猜測題。根據(jù)畫線詞前的 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，畫線詞應指的是對塑料袋的禁令。
【微技能】根據(jù)上下文信息判斷指代內容
任何一篇文章中的句子在內容上都不是絕對孤立的，都與句子所在的段落及整篇文章有關。在做推斷詞語指代的內容這類題時，學生應利用上下文提供的情景和線索，進行符合邏輯的綜合分析并依此來推測其所指代的內容。
本題中，根據(jù)畫線詞前的 these 一詞可知，headwinds指的是前文出現(xiàn)過的內容，所以我們可以據(jù)此鎖定解題依據(jù)的范圍，即這一段的前三句。再細讀這三句話可知，加利福尼亞州的90個城市都禁止使用塑料袋。由此可判斷 these headwinds 指代上文提到的“禁止使用塑料袋”，后文也介紹了針對這樣的情況廠家想出的對策。因此 Bans n plastic bags正確。
3.D 細節(jié)理解題。根據(jù)第四段第三句 Hwever，lnger lasting reusable bags ften require mre energy t make 可知，更加耐用的環(huán)保袋在生產過程中需要耗費更多的能源。
4.A 主旨大意題。通讀全文內容可知，本文主要介紹了塑料袋、紙袋以及可循環(huán)利用的環(huán)保袋各自的利弊，故A項為最適合本文的標題。
