1The word "ubiquitous" (Line 2, Paragraph 3) most probably means_____. A.tomnipresenB.popularC.commonD. usual 参考答案： A 猜词题。根据上下文来判断该词的意思，文章第四段讲述当时由于加拿大教会和环境组织因害怕制造容器大量使用塑料，所以发动了许多运动。而因为Nalgene瓶子可以重复使用，具有环保特征，因此在校园和许多地方应该是普及了，到处能看得到了。答案为A。----------------------------------------2Which one of the following statements is TURE of the local law passed by San Francisco’s board of governors?
