to+V 放句首为动词不定式，用法与V+ing差不多，多用于后面所说的事情还没有发生。例：To be a author is my dream.
V+ing 放句首是动名词，其相当于名词，例：Doing lots of exercise is good for health.
一般来讲，to+ v. 表主动，表将来，表一次行动作。
-ing 表主动，表进行。
动词不定式与动名词的一些用法：）
不定式与动名词都可以在句中作主语、宾语、表语和定语,但用法不尽相同。
1．作主语
一般情况下,不定式与动名词作主语可以互换,也常常可以用it充当形式主语,而把不定式和动名词放在句子的后半部分。但二者也有区别,不定式常常指某次具体的、将要发生的行为;而动名词则表示一般的、抽象的行为。例如:
To save money now is not easy. 现在攒钱不容易。
Saving money is a good habit. 攒钱是个好习惯。
2．作定语
不定式多为后置定语,动名词多为前置定语;不定式多表示将来的动作,动名词只能表示事物的属性、用途等。例如:
He is looking for a room to live in.他正在找一间房子去住。
Take these sleeping pills and you\'ll sleep better. 吃了这种安眠药,你会睡得更好。
3．作宾语：
有些动词后只能跟不定式作宾语,不能跟动名词作宾语;有些动词后常跟动名词作宾语,不能跟不定式作宾语;有些动词后跟不定式和动名词作宾语皆可,
如果表示一种命令的口吻的话 那么可以看作是祈使句 这个句子应该是动词原形放在句子的开头 但是很多情况下 动词前面会有一个please(请)来修饰
例如:Open the door!开门
如果句子没有一种命令的语气时 而是单纯的动词含义时 应该是动词的doing形式作主语
例如:Eating too much is bad fou you!吃的太多对你不好! (另外 注意 刚才2楼那为的第二个例句 应该是 Eating )
祈使句动词一般放句首。
Come on!
动名词做主语的时候一般放句首。
Eatting vegetables is good for health.
祈使句动词一般放句首。
Come on!
动名词做主语的时候一般放句首。
Eating vegetables is good for health.
一般需要做主语时放句首,比如拳击是个很好的运动翻译成:boxing is a good sport
