这里有这样的语法点:动名词做主语+it 形式主语.句子本来是Being your age is not easy.(Being是be动词be的动名词形式)为了避免头重脚轻,用it做形式主语,真正的主语被放到了后面.同理,后半部分句子的真正主语是to have these feelings,这里又是不定式做主语了。对比一下你会发现,两句话的主语都是由动词组成,但动词不能直接作主语,需要用到它的非谓语形式(这里分别是动名词和不定式),才会有了这样的表达方式。一个句子有两个主语不矛盾吗在这个句子中,整个句子是由and连接的并列句,不只有两个主语,更是两个完整的主系表结构。 其他时候,一个句子一个句子也可以有两个主语。You and I are talking about grammar.(你和我在讨论语法)主语就是两人(你和我)。

会做么People often remember what they were doing when they heard the news of important events in history.这个句子的event为什么要加s?event是一个可数名词,如果是单数形式,前面必须有冠词(a、an、the)或者物主代词(my、your之类的),没有的话就需要用复数。On this day,Dr.Martin Luther King was killed.这个句子的killed是什么词?was killed是这句话的谓语动词,was作为助动词与动词kill的过去分词构成了被动语态。I had trouble thinking clearly after that because I was very afraid.这个句子的think为什么要加ing?think前面省略了介词in,介词后面的动词要用ing形式。He got angry with me after that.这个句子的get为什么要用过去式形式?什么是方式状语?Children should learn to do things by themselves.这个句子的thing为什么要加s?I got the latest CD player as a birthday present yesterday.It was just a dream come true!这个句子的latest是什么意思?I've always wanted to visit New York,so going there on vacation next month will be a dream come true for me.这个句子的want为什么要加ed,还有go为什么要加ing?
