2.比较man 和 human being比较man 和 human being
man和 human being都有“人”的意思。human being是可数名词，a human being表示单个的人，human beings 则泛指所有的人，或指“人类”；man表示“人类”时为不可数名词。
例如：he was the only human being on the island. 他是那个岛上唯一的人。
man can do anything. 人类可以坐任何事情。
earth 意为“在地球上”
例：we live on earth.
than 意为“超过；多于”，相当于介词over,如：
there are more than 5000 adjectives in that dictionary. 那本词典中收录了5000多个形容词。

more than “多于”，常和数词连用。

【注意】as……as和not as/so……as后与人称代词连用时，用主格或宾格均可，如：he is as tall as i (me).但人称代词后有动词时，必须用主格，如：

learn 表示“学习，学会”的意思，而learn about表示“了解，学到关于…的内容”。如：

such as 表示举例，意为“例如，诸如此类的，像……那样的”，相当于like或for example。

拓展】such as & for example
①such as一般用来列举同类人或物中的几个例子，插在被列举的例子和前面的名词之间，as后没有逗号。在使用such as时应注意后面列举事物的数量不能等于前面所提事物的总和，若相等时用namely或that is. 如：
he has been to many countries, such as america, japan and germany.
he can speak three foreign languages, namely chinese, english and french.
for example一般只举同类人或物中的一个为例，作插入语，可置于句首、句中或句末。
for example，air is invisible.
