在做主被動置換題目時遇到的問題,想請問各位:
1.Does Prof.Shapiro teach that course ? No, he doesn't
→(被動) [Is] that courses be taught by Prof. Shapiro? No, it [is] not taught
by him.
書上沒有提及be V 與助動詞的置換,查過網路好像是因為一般V在疑問句or否定句下無法
表達,需要助動詞的幫助,想請問be V與do/does是可以隨意置換嗎? 還是有主被動的限制
? 從這邊看好像是被動用be V, 主動用do/does
2.When was ink first used? No one knows when [ink was] first used.
[]中可以順序可以對換嗎? →No one knows when [was ink] first used.
