except do和except to do的规律


【问】

  1. The government has few options except ____ (keep) interest rates high.
  2. She had nothing to do except ____ (spend) money.

答案:1. to keep 2. spend

问题:except后用do和to do有何规律?

【答】

except前如果有实义动词do,如2句,则用except do;如果except前没有实义动词do,如1句,则用except to do。

再如:

  • He wouldn’t talk about work, except to say that he was busy.

前半句没有do,所以用except to say。

注意,这里说的do是实义动词的do,而不是助动词的do。例:

  1. We do not know what to say, except to keep silent.
  2. We do not know what to do, except keep silent.

1句中的do是助动词,不是实义动词,所以except后是to keep;2句中的第二个do是实义动词,意为“做”,所以except后是keep。
