句子中，哪些情况动词加ing?

首先，经常用的是句子表示现在进行时态的；动词作主语时要用现在分词形式，即加ing；还有种句式是现在进行表将来的：be going to.

be动词(is.am.are).介词后面加ing形式。还有固定的词组搭配要记住 某些动词后出现非限定性动词时只能用动名词作宾语，不能用不定式。常见的此类动词有：advise, allow, permit, avoid, consider, enjoy, finish, give up, cannot help, imagine, include, keep, keep on, mind, miss, put off, delay, practise, resist, suggest, depend on, think about, set about, succeed in, worry about, burst out, insist on, can’t stand, be used to, get used to, devote…to…, look forward to, pay attention to, get down to等。如： they went on walking and never stopped talking. 他们继续走，说个不停。 i found it pleasant walking along the seashore. 在海滩上走真是乐事。 （2）作介词的宾语 we are thinking of making a new plan for the next term. 我们正考虑为下学期制定新的计划。 shall we have a rest or get down to doing our work? 我们休息呢还是开始干活？ （3）作形容词的宾语 the music is well worth listening to more than once. 这种曲子很值得多听几遍。 we are busy preparing for the coming sports meet. 我们正为马上到来的运动会忙着做准备。 3、作表语 动名词作表语时句子主语常是表示无生命的事物的名词或what引导的名词性从句。表语动名词与主语通常是对等的关系，表示主语的内容，主语、表语可互换位置。 your task is cleaning the windows. 你的任务就是擦窗户。(cleaning the windows is your task.) what i hate most is being laughed at. 我最痛恨的就是被别人嘲笑。 (being laughed at is what i hate most.) 4、作定语 动名词作定语往往表示被修饰词的某种用途。如： a walking stick ＝a stick for walking=a stick which is used for walking a washing machine=a machine for washing=a machine which is used for washing a reading room=a room for reading=a room which is used for reading a measuring tape=a tape for measuring=a tape which is used for measuring sleeping pills=pills for sleeping=pills which is used for sleeping
