单选题
2. Water pollution, together with old tins and other forms of garbage, ______ many problems in our large, industrial city today.
【正确答案】
A
【答案解析】 水污染,以及用过的锡罐和其他类型的垃圾,在的工业化大城市中引起很多问题。上述四个选项中,三个表达复数概念,一个为单数,这时要注意其对应的主语是单数还是复数概念。本句的主语是water pollution,紧跟其后的介词短语不是主语的一部分,而是状语。此外,如果主语后面有as well as,as much as,rather than,more than,no less than,along with等引导的词组时,其谓语的单数形式与此短语无关,而通常按语法一致的原则,即按主语的单复数而定。例如:The captain,as well as the coaches,was disappointed in the team.队长和教练们对球队的表现很失望。
