题目

18and that the most beautiful discovery that true friends make is that they can grow separately without growing apart.
而最重要的发现是真正的朋友不会因为分隔两地而产生隔阂.
1.“that”在这起什么作用,反正不是引导词,怎么译?
2.“and that the most beautiful discovery that true friends make”这里是不是省略了“what”?应该这样：and that the most beautiful discovery that what true friends make…….对不?一般是在什么情况下会用到类似这样的省略?
3.“ that they can grow separately without growing apart”中without growing apart修饰谁?句型分析,怎么翻译?“分隔两地而产生隔阂”这句中哪有“两地”“产生隔阂”?“ separately”修饰“grow”吗?“grow”在这译为什么?
