Yes-no問句改成間接問句的句型 (課本P.67)
※Yes-no問句改成間接問句時，不是用Wh-疑問詞，而要用whether(是否)或if(是否)來引導此間接問句。
★ Yes-no疑問句中含be動詞：形成間接問句時，主詞和be動詞互換。
|
Be動詞 + 主詞 + …？ à主要子句 + whether/if + 主詞 + be動詞？ 例：Is Jenny tall? à Do you know whether/if Jenny is tall? |
練：Is it raining outside?
à I don’t know_____________________________________________
★ Yes-no疑問句中含助動詞do, does, did：形成間接問句時，動詞需視主詞人稱的單複數和時態作變化。
|
助動詞 + 主詞 + 原形動詞 …？ à主要子句 + whether/if+主詞 + 動詞？ 例：Does he open the window? à Please tell me whether/if he opens the window. |
練：1. Do you want to go swimming?
à I’m not sure ________________________________________
2. Did she turn off the lamp?
à Can you tell me ___________________________________________
★ Yes-no疑問句中含和助動詞 will, can, should…或have/has + p.p.：形成間接問句時，主詞和助動詞互換。
|
助動詞 + 主詞 + 原形動詞 …？à主要子句 + whether/if + 主詞 + 助動詞+ 原形動詞？ 例：Can the damage be reduced?à Tell me whether/if the damage can be reduced. |
練：Will they join the club?
à I want to know ________________________________________
練：Have you been to Japan?
à I’m not sure ________________________________________
★ 比較1：引導間接問句的whether和if意思上相同，但不同的是，whether的子句可以加入”or not”，而if的子句通常不加。
例：I don’t know whether she likes me (or not). I don’t know if she likes me or not.
★ 比較2：
- a. 當從屬連接詞if做「如果」解釋，要表達「未來」時，條件句(副詞子句)的動詞需用現在簡單式。例：If David joins the game tomorrow, we will win.
- b. 當if做「是否」解釋，要表達「未來」時，間接問句(名詞子句)的動詞需用未來式。
例：I don’t know if David will join the game tomorrow.
