8）I can’t help to finish her work, because I haven’t finished mine yet. I can’t help crying when I heard the news.
小结：
1．特征： 单个的动词-ing形式作主语，谓语动词用单数。 2.句型：
1）doing 作主语句型： Doing …. + V + O 2）但有些含有动名词的句型，为避免句子主语
太长，通常用it作形式主语，-ing形式作真正 的主语。下面列举几种最常见的句型：
Eg. It’s no use crying over spilt （倾倒出）milk. ① It +be +no good /use doing…做…无益/无
=My coat needs to be washed.
Eg2. I look forward to receiving your letter.
②下列动词常以动词不定式（to do）作宾语。
三个希望两答应 hope; wish; want ; agree; promise
两个要求莫拒绝 demand; ask; refuse 设法学会做决定 manage; learn; decide 不要假装在选择 pretend ; choose
动词want，need，require作“需要”解时，后面的动词 用动名词作宾语时，且与句子主语有逻辑上的动宾关系， 这个动名词的主动式表示被动意义。
3)give up, can’t help, look forward, have
trouble …. +doing
Eg1. My coat needs washt everything done on time.
Let’s try doing the work some other way. try to do sth.: 设法、努力做某事 try doing sth.: 尝试做某事
7）He said nothing but just went on working. After her early teaching career she went on to become a doctor.
consider, finish, delay 喜欢 设想 不介意
fancy, enjoy, appreciate, 面对 坚持 不放弃 imagine,
mind 避免 冒险 请原谅 face, insist on, give up
2)need, require, want + doing = need to be done 注意:主动表被动
3) I regret to tell you that you can’t work here any more. I regret not taking your advice.
regret to do sth 对马上要发生的事抱歉、 遗憾，常和say, tell, inform 等词连用。 regret doing sth. 后悔做过某事。
