Answer 1

the reason 主句主语
why he came late 从句

that he didnt catch the early bus表语从句
1) 谓语动词在句中可单独作谓语，而非谓语动词不能单独作谓语。

玛丽教我们英语。（teaches 动词作谓语）
Mr.Victor came to our classroom to have a talk with us last week.
维克托先生上周来我们教室和我们谈话。 （to have a talk.... 不定式作目的状语）
2) 谓语动词受主语的人称和数的限制，而非谓语动词形式没有这种限制。
Larke likes the pop music.
拉克喜欢流行音乐。 （动词用单数第三人称形式，作谓语）
Larke has nothing to do today.
拉克今天没什么事要做。（do 用原形，补充说明nothing）
非谓语动词的特征
1 如果非谓语动词是及物动词，后面须跟宾语。
Studying English is my favorite.
学习英语是我的爱好。（studying 后跟宾语）
To help him is my duty.
帮助他是我的责任。（help 后跟宾语）
2 非谓语动词可以带有自己的状语或逻辑主语。
Working under such a condition is terrible.
在这样的环境下工作太可怕了。(under such a condition 是 working 的状语)
It's too difficult for him to master English in such a short time.
他在这么短的时间内掌握英语太难了。（for him 作不定式的逻辑主语）
3 非谓语动词仍有语态和时态的变化。
I am sorry to have kept you waiting long.
对不起让你久等了。（to have kept...是不定式的完成形式）
Seen from the mountain, the city looks much more beautiful.
从山上看，这座城市美丽多了。（Seen from...是分词的被动形式）
4 非谓语动词在句中可以当成名词或者形容词来使用。
Our coming made him happy.
我们的到来使他很高兴。（coming 起名词作用）
There are two big swimming pools here.
