答案对,原因不太明了!这样也许更清晰——
1、选C.
句子意思：
我们未被告知他们【是否】会按时来.【如果】他们到了,我将立刻告知你.
考点：
if 的不同意思和引导不同从句的时态搭配.
关键：
if表示【是否】,引导宾语从句.时态依据句子意思和前后关系搭配使用.
这里,句子意思表示【是否将会来】,因此,用一般将来时.
if表示【如果】,引导条件状语从句.主句用一般将来时,if从句用一般现在时代替一般将来时.
所以,只有C正确.
2、
It is( )book that it is sold out within 30 minutes
A.such interesting a B.so a interesting
C.so interesting a D.a such interesting
选C.
考点：
such...that和so...that连接单数可数名词的结构.
知识链接：
such+a/an+形容词+单数可数名词
so+形容词+a/an+单数可数名词
例如：
She is such a good teacher that we all respect her.
=She is so good a teacher that we all respect her.
祝你开心如意!

C
根据句意：我们还没被告知，他们是否准时到，假如他们准时到，我马上告诉你。
“是否”if可用于将来时， “假如”if需用一般时代替将来时。
