set
1.set用作“放…（在那里）”解不及put通俗。
2.The sun has set和The moon is setting等句子里不可在set或setting后面加上down。
3.下面两句意思不同：
- I have set him a task. （我已经给他一件工作。）
- I have set him to a task. （我已经使他开始做一件工作。）
4.下面各句里的set的宾语后面都接现在分词：
- That set me thinking. （那件事使我思索起来。）
- The joke set all of us laughing. （这笑话使我们都大笑起来。）
- Her absence set them wondering. （她的缺席使他们奇怪起来。）
- The opening of the door set the bell ringing. （门一开使铃响起来。）
在这四句里的thinking，laughing，wondering和ringing前面加上to也可以，但不很普通。
下面各句里的set的宾语后面都接不定式：
- He set his son to saw wood. （他叫他的儿子锯木头。）
- She set her cat to catch mice. （她让她的猫捉老鼠。）
- Who set you to pick the flowers? （谁叫你采这些花的？）
把这三句里的to saw，to catch和to pick改作to sawing，to catching和to picking也可以。用了动名词便把那动作看作一件工作，如He set his son to saw wood是“他叫他的儿子锯木头”。He set his son to sawing wood是“他叫他的儿子做锯木头的工作”。
set myself（或yourself等）to...（不定式）作“决意…”解。例如：He has set himself to read through the long novel.
5.set to work（开始工作）和set... to work（使…开始工作）两种表达方式里的work是名词，不是动词。后面都可以接不定式。例如：I have set to work to learn German. 和I have set her to work to learn German. 有时接分词。例如：I have set to work learning German. 和I have set her to work learning German.
6.I have set to learning German（我已经开始学习德语）里的to可以被当作介词（learning是动名词），也可以被当作副词（learning是现在分词）。
