关于第一题，但IF是“是否”的意思时，从句时态不是会受到主句过去时态的影响吗？那不是应该选C吗？
第二题也一样，主句是过去式，从句不是应该也是过去式吗？

could表示委婉的语气,比can更客气,不是过去时.
1.b 句中有tomorrow所以要考虑将来时,排除A、C选项； 宾语从句中从句部分要用陈述句语序,故答案为b.
2.a 宾语从句中从句部分要用陈述句语序,可排除c、d选项； 飞到香港要花多长时间是一个客观事实,不是发生在过去的事情,所以用一般现在时,故答案为a.
解答宾语从句一类的习题关键要考虑用“陈述句语序”,这是主要出题点.

第一题：c；意思：你能告诉我明天是否会下雨？（could表示委婉，婉转的语气）
第二题：a；意思：你能告诉我乘飞机去香港要多长时间吗？

b a
第一题“能告诉我明天是否会下雨吗？”是一个将要发生的动作。所以用will，宾语从句还要倒装，选b。
第二题 “你告诉我到香港多长时间吗？”只是问当香港的时间，不是强调我要去香港花多长时间，所以相当于是常识性的东西，不是一个将要发生的动作。其实在a中加will take也不错
另外前面的could是说话的委婉语，不是过去式，和时态没关系...

第一题：B A 肯定排除，没有疑问词 C和D if it will rain tomorrow等于whether it will rain tomorrwo，都是宾语从句，if\whether引导选择形势宾语从句。
第二题： A

作宾语从句，关键看时态、人称和语序，所以D错，could表委婉语气，并不是过去式。选B
第二题也一样，could表委婉语气，故选A
