5. alive活着的；存在的
Who’s the greatest man alive ?
〖点拨〗alive ; living ; live ; lively ; life ; lives 这些词都有“活着”之意，它们的用法各不相同。
1）alive 意为“活着”，侧重说明生与死之间的界限，既可指人，也可指物；可用来作表语，后置定语或宾补。虽有死的可能，但还活着。例如：
The badly wounded soldier was still alive when taken to the hospital .
He is dead , but his dog is still alive . 他死了，但他的狗仍然还活着。
No man alive is greater than he . 在活着的人中没有人比他更伟大了。(注：此时 alive 含有“在所有活着的……之中”)

living 还可用于短语，例如：make a living 谋生。
3）live “活着的”，通常指物，不指人，常用来作定语放名词的前面。还指“实况转播的”。例如：

We use this tense to show that something is being done at the present time .
For the present we do not need that book , so please go on reading it yourself .

〖明晰〗这三个短语都可表示“某一天”，但用法不同。
