1. 表示许多多个，通常只用作定语。如：
I have various letters to write. 我有好几封信要写。
Various people said they had seen the accident. 许多人都说目睹了这次事故。
2. 表示各种各样的形形色色的种种的等，多用于名词前作定语，但有时也用作表语。如：
For various reasons I’d prefer not to meet him. 由于种种原因我还是不见他为好。
We’re making changes in various directions. 我们正在多方面进行改革。
His excuses are many and various. 他的理由（借口）既多又是五花八门。
3. various与different的区别：
(1) various表示各种各样的各不相同的等，主要指彼此不同且种类繁多，强调异而多。如：
There are various ways of cooking an egg. 鸡蛋有各种各样的煮法。
There’s been snow today in various parts of the country. 今天全国各地都下了雪。
(2) different表示不同的，指的可能是种类不同、不相像、不一样、不是同一个等，只强调异，不强调多。如：
Mary and Jane are quite different. 玛丽与简大不一样。
This is not what I want; I want a different one. 我要的不是这个，我要一个不同的。
(3) 比较下面两句：
He gave various reasons (=a number of different reasons) for being late. 他为自己的迟到举出了种种理由。
This time he gave different reasons (=not the same as last time) for his being late. 这次他为自己的迟到举出了不同的理由。
(4) 由于various不仅强调异而且强调多，所以其后接的名词通常用复数；而different强调的只是异而不是多，所以其后的名词可以是单数或复数。
