Reading English aloud in the morning is a good way to learn English. 2. Cheating on an exam ruins one's character. 考试作弊毁坏人的性格。 3.Being careless is not a good habit.4.As is known to all,_____________( 吸烟) does harm to people’s health.5.Mary’s (不可用Mary) being ill made her mother upset.6.His (不可用Him) ________________________________ (不按时起床) made his mother angry.smokingnot getting up on time2、动名词作主语时,对于一些比较长的动名词短语,一般采用"It is …"和"There is …"两种句式来表示。例如: It is no use waiting for him any longer. 等他是没有用的。 There is no joking about such matters. 这种事开不得玩笑。 3、动名词作主语与不定式作主语的区别:动名词作主语通常表示抽象的或泛指的动作,不定式通常表示具体的动作或行为,如:It’s no use crying over spilt milk. (抽象,泛指)He realized that to go on like this was no use. (具体)4、在实际运用中,一般可以互换,差异不大。但在下列几种情况中不能互换:当表语是动名词时,主语也要用动名词;当表语是不定式时,主语也要用不定式,如: Seeing is believing. = To see is to believe.5、动名词和不定式作主语,一般都可以使用形式主语it,而将动名词或不定式放在句尾。但是在下列句型中,一般宜用动名词,不宜用不定式来代替:It’s no use doing … It’s no good doing… It’s a waste of time doing …二、作表语1、动名词作表语与现在分词作表语的区别:动名词作表语时相当于名词,说明主语的含义及内容,它与主语是同等关系,主语与表语互换位置不影响句子的基本含义,但不可用副词来修饰。如:My job is looking after the children. = Looking after the children is my job.Our duty is serving the people. = Serving the people is our duty.以上两处是动名词作表语,可以和主语互换位置,不影响句子的基本含义。What I hate is _________________________(talk) with such people.我讨厌与这样的人说话。talking2、现在分词作表语时相当于形容词,说明主语的特征、性质、状态等,主语与表语不可互换位置,但可用very, quite等副词来修饰,如:令人......的。The situation is encouraging. 形势鼓舞人心的。This cake is very inviting. 蛋糕诱人。The volleyball match we watched was very exciting.3、动名词作表语与不定式作表语的区别:动名词作表语时表示比较抽象的一般行为、习惯;不定式作表语时表示具体的某一次动作,特别是将来的动作,试比较:My favorite sport is swimming.The first thing for us to do is to improve our pronunciation.三、作宾语1、能用动名词作宾语的动词有两类:一类是只能用动名词作宾语的动词,其中有:advise, allow, permit, avoid, consider, enjoy, finish, give up, cannot help, imagine, include, keep, keep on, mind, miss, put off, delay, escape,practise, resist, suggest, depend on, think about, set about, succeed in, worry about, burst out, insist on, can’t stand, be used/accustomed to, get used to, devote…to…, look forward to, pay attention to, get down to, key to,approach to,lead to, stick to, 等。另一类是既可以用动名词,又可以用不定式作宾语的动词,其中有:begin、start, forget、remember ,regret ,hate、like、plan、prefer、 try、stop、need、can’t afford等。(1) 动名词跟在及物动词后做宾语。例如: I enjoy working with you.After hearing the funny story, all of us couldn't help laughing ear to ear.
