动名词要点提示 动名词，就是动词后加ing 的形式，即doing sth. 它的作用相当于一个名词，在句中做主语或者宾语，所以叫做“动名词”。英语中，有些动词后通常接动名词，如appreciate, enjoy, cant help 等。另外，作介词宾语的话，肯定是用动名词。还有些动词短语后面的to 是介词，也要用动名词作宾语，如get used to doing sth, look forward to doing sth. 等。动名词可以有被动态（being done），如 being seen；它也有否定形式(not doing)，如not being able to；动名词前还可以加逻辑主语，如your coming to my party, him offering help to us 等。Exercises:1.
