常见误区
❌ 错误:“This book intends to teach English.”(书不能“主动意图”)
✅ 正确:“This book is intended to teach English.”
注意:“intend” 是及物动词,通常由**人**作主语。当主语是**物**时,必须使用被动语态 “be intended to”。
近义表达
- be meant to —— 更口语化(例:This button is meant to turn off the device.)
- be designed to —— 强调设计目的(例:The car is designed to save fuel.)
- be supposed to —— 有时可互换,但更侧重“应该”或“按规定”
