这里关键是时态 你如果直接说"than in the 1960's",就是这个意思: fewer people will enter X in the 1980s than (will people) in the 1960's Make sense? No!!!! Because "in the 1960's" is a past time indicator, you have to change the tense. fewer people will enter X in the 1980s than did people in the 1960's. 如果我现在说:fewer people will enter X in the 2030's than in the 2020's. 这没问题,因为同样可以用将来时表示。 所以说一旦有tense shift, 或者单复数的变化,必须补出来。这其实是parallelism的要求。
As a result of the continuing decline in the birth rate, fewer people will enter the labor force [in the 1980’s] than did [in the 1960’s and 1970’s]
看到这样一句话,说这里的did不可省。。。为什么啊?!我觉得可省啊!省略就是时间状语的比较,没啥不可以啊~~求教NN~~

赞~~ 再补充一下,有些童鞋可能问怎么知道1980是将来,1960、1970是过去,句中有个continuing,说明decline 已经发生,同样可以推理出很少有人进入劳动市场了,这件事也发生了,因此用did。 |
