lily has some ideas about what she is going to be when she grows up 为什么用what 不用that
what的意思是:什么(职业)
that没有这个意思

what she is going to be 她打算当什么,what引导的名词性从句做about的宾语
不能用that来引导这个句子,它只能引导一个完整的句子做名词性从句,但she is going to be 并不是个完整句。

what 和 that 都可以引导从句,不同的是what 可以充当句子成分,不可以省略。that 不充当句子成分,可以省略。
本句中what做be 的表语,意为什么什么的事物,所以不能省略,若换成that ,没有这个意思,句子意思就不完整。所以要用what。

about 后面的部分为she is going to be 是宾语从句,在宾语从句里to be缺宾语,所以用what来引导宾语从句。这句话翻译为:莉莉对她长大以后会成为什么有一些想法。
