Answer 1

1.what 引导了一个主语从句，在从句中充当desire to do的宾语。在名词性从句当中，缺少主宾表的话，一般都填what。
在杨利伟成功环绕地球飞行后，我们宇航员最想做的事情就是在太空漫步。
2. that引导一个表语从句, is 是系动词，所以that引导的是表语从句。从句中是一个事实，没有疑问在里面，所以用that。
3、That's why后跟结果，That's because 后跟原因。
eg.He didn't catch the bus, that's why he was late.
He was late, that's because he didn't catch the bus.
4、that 这里为一个代词，代指前面的important questions
One of the most important questions 是主语
they had to cinsider 是定语从句，修饰主语
was是系动词 _that__ of public health 是表语追问

额，最后一题那个为什么一定填that ， what which this 都没有指代作用么？
还有那个of public health 为什么不是定语修饰that

谢谢了

追答

what, which是没有指代作用，它们一般用来引导从句。只有that可以代替句单数可数名词或不可数名词，以避免重复。

Answer 2

1、 _what_ our astronauts desire to do is walk in space
what 引导了一个主语从句，即waht our astronauts desire to do 就是这个句子的主语，其意义就是用一个句子的形式当做一个主语
2、 _that__ singing stars are centered on by masses of teenagers today
that引导一个表语从句，singing stars are centered on by masses of teenagers today全部都是表语，也就是is后面的句子成分
3、that's because 译为：那是因为....
4、that 这里为一个代词，代指前面的important questions
One of the most important questions 是主语
they had to cinsider 是定语从句，修饰主语
was是谓语
_that__ of public health 是宾语
此局完整的是：
One of the most important questions which they had to cinsider was that of public health
