條件句的動詞時態

1. If we  take (to take) the MRT, we  will arrive (not/to arrive) in time.
2. If it  rains (to rain), the children  won't go (not/to go) for a walk.
3. If Dick  doesn't buy (not/to buy) the book, his friends  will be (to be) angry with him.
4. If she  doesn't read (not/to read) the novel, she  won't pass (not/to pass) the literature test.
5. If I  do not argue (not/to argue) with my father, he  will lend (to lend) me his car.

條件句是由主(主要子句)、從(從屬子句)句的動詞依所使用的時態來描述結果的可能性。第一類條件句的 If-子句時態用現在簡單式，主要子句時態為 will/won't + 動詞原式，表示未來有可能實現的假設。
