【題目】"Can you solve the problem yourself?" Our science teacher asked Bob. (改為賓語從句)

Our science teacher asked Bob _________he _________solve the problem himself.

【答案】whether/ if could

【解析】

句意：我們的科學(xué)老師問鮑勃：“你能自己解決這個(gè)問題嗎？”

主句是一般過去時(shí)，從句使用過去的某種時(shí)態(tài)，此句“Can you solve the problem yourself?”是一般現(xiàn)在時(shí)，需改為一般過去時(shí)。賓語從句的語序是陳述語序，如果“一般疑問句”做賓語，需借助if/whether引導(dǎo)，再改為陳述語序。故答案為 (1). whether/ if (2). could。
