1)當(dāng)let后只有一個(gè)單音節(jié)動(dòng)詞,變被動(dòng)語態(tài)時(shí),可用不帶to 的不定式。例如:
They let the strange go.他們放陌生人走了。
——> The strange was let go.
2)當(dāng)let 后賓補(bǔ)較長時(shí),let 通常不用被動(dòng)語態(tài),而用allow或permit 代替。例如:
The nurse let me go to see my classmate in the hospital. 那護(hù)士讓我去探望住院的同學(xué)。
----> I was allowed / permitted to see my classmate in the hospital.
