类似词语：anything; something; nothing; anywhere; somewhere warm 暖和的地方； nothing serious 没什么严重的；
eg:
There is something interesting in today’s newspaper.
今天的报纸上有一些有趣的事。

3. None of us likes pollution.
众所周知，没有人喜欢污染。
none与no one 的区别：
① none 指三者或三者以上的“没有，都不”，既可指人也可指物，后常跟of 的短语; 作主语时，谓语动词既可用单数也可用复数；构成“none of +名词/代词”结构，当名词是不可数名词时，谓语动词用第三人称单数；当名词是复数时，谓语动词用单复数均可。
eg:
He has read none of these books.（指物）这些书他一本都没看过。
None of my friends like/ likes drawing.（指人）我的朋友们没有一个喜欢画画。

② no one只指人，后不能跟of 的短语; 作主语时，谓语动词只用作单数。eg:
No one is here. 没有一个在这儿。
③ none回答how many/ much的问题；no one回答who的问题。
eg:
—How many students come to school by taxi —None.
——有多少的学生搭出租车来上学？ ——没有人。
—Who is in the room —No one.
——谁在房中？ ——没有人。

4. Everyone should care for wild animals and plant more trees. 每个人都应该保护野生动物并且多种一些树木。
everyone 表示“每个人”，只指人，不能指物，不接of短语，它强调整体，如果后面接表范围的of短语，则写成every one.
eg:
He knows everyone in our class. 他认识我们班里的每一个人。
6. We should do everything we can to protect the environment. 我们应尽一切努力保护环境。
此句we can 作everything 的定语， 省略了引导词that及从句中的谓语do，意为“一切能做的事情”。
