你开始上班时,就要早起一些了,是吗?
Youll have to cross the line by the footbridge.
你必须从天桥过马路。
C 第三人称的例句
这时must主要用于书面指令或指导:
Railway company:Passengers must cross the line by the footbridge.
铁路公告:旅客必须由天桥过马路。
Office manager:Staff must be at their desks by 9∶00。
办公室经理:工作人员必须在9∶00前到达各自的办公桌前。
Regulation:A trailer must have two rear lamps.
规章:拖车必须有两盏后灯。
只不过是讲述或评论他人的义务时,则用 have to:
In this office even the senior staff have to be at their desks by 9∶00.
在这个办公室,就连高级职员也要在9∶00前到达他们各自的办公桌前。
She has to make her childrens clothes.She cant afford to buy them.
她必须自己给孩子们做衣服穿。她买不起。
Theyll have to send a diver down to examine the hull.
他们必须派潜水员下水去检查船体。
如果用 must代替上面例子中的 have to,就可能意指说话的人有权下命令这样做。
