at hand、on hand、in hand
这三个词组都含“在手头”、“在手边”的意思，用法区别甚微，只是侧重不同而已。
at hand 有二个基本用法：① “在手边”、“在附近”；②“即将到
来”。常用 close、near、 ready 前置修饰之。
●“在手边”、“在附近”，侧重强调就在手边、近处，随时可用之，含 have
something easy to reach，which can be used if needed 的意思。在句中可
作状语、补语或
后置定语。

表语。

追答in hand 侧重强调手中掌控的的物或事，随时可用，随时可做（in one's
possession ready to be used or done），也可表示手头正在进行的事。所以
in hand 除了表示“在手头”、“在手边”的意思外，还可表示“控制中”或“在进
行中”。
