Answer 1

答案：A

翻译：大量的棉花已经被船运到世界各地，而大量的竹篮将要被出口到一些西方国家。

解释：出题考查quantity的用法。
1. a large quantity of和large quantities of都可以修饰可数名词复数或不可数名词。
且如果这两组短语做句子主语时，谓语动词的数采用就远原则，即和quantity的数保持一致。
如果是quantity，则谓语动词用单数；如果是quantities，则谓语动词用复数。
2. 第一空为quantities，所以谓语动词用复数形式have，不用单数形式has，排除BD；
第二空为quantity，所以谓语动词采用单数形式is，不用复数形式are，排除C。
所以正确答案为A。
