我选的B, A是错的,costs 不可以用单数is 另外关于than的用法有两个,要么倒装要么省略 倒装:bla bla bla than were they bla bla bla 省略:bla bla bla than (they) (were) bla bla bla ()()内容都可省略,变型成a greater proportion than were in any previous election 或者 a greater proportion than they in any previous election, 或者a greater proportion than in any previous election 举例:I am taller than (I) possibly could (be). |
