1、had arrived表示虚拟“她加入到的话”,是在虚拟条件,而could have arrived是用来虚拟结果的.
比如这个例句：If I had taken your advice,I would have passed the exam.
2、问题的意思是：-很抱歉,简.对你没有起到太大的帮助.
-当然有帮助了.事实上,作用相当大.
这个"sure it was" 是用来与后面的”it was most helpful“相连的.B、C、D的话就是没有帮助,和后面的句子就会有歧义了.
希望可以帮助亲.

. could have arrived
是指本应该到，却未到
Jane在事实上认为这是一个很大的帮助

1.-- Jenny has failed to seek advice from Professor Li on the problem again.
-- What a shame! If only she ___ before he went abroad on business.
A. arrived B.had arrived C.should have arrived D. could have arrived
B的语法可以理解...不过D的问题在哪里呢？
答：这个问题不太好回答。
这是虚拟语气，表示一种愿望，针对过去发生过的事情。if only可以换成：How I wish 或I wish+(that)从句。
从对话看，詹妮没能在李教授去国外出差之前到。（She didn't arrive before Professor Li went abroad on business.
第二个人说：真可惜了。要是。。。就好了。=How I wish that she had arrived before ....
wish后的宾语从句，其时态要前进一格，原来是过去时，所以用过去完成时，这你懂的。
我们再来看D项：
How I wish that she could have arrived before ....
宾语从句中，没有这样的时态。 could have done sth. 表示虚拟时，是用在if -虚拟条件句之主句中的。也是对过去发生过的事情的假设。表示：假如。。。的话，她就能到了。比如：
If she had got up earlier, she could have arrived before Professor Li went abroad on business.

2.-- Sorry,Jane. That wasn't of much help to you.
--Oh,___ . As a matter of fact , it was most helpful.
A. sure it was B. it doesn't matter C. of course not D. never mind
为什么选A呢...实在不理解这逻辑= =
答：逻辑就：当对方说的是否定句时，如果你表示不同意，用Yes. 同意用No.
从后句判断，简是不同意对方的说法的（对不起，没帮上你什么忙）。
她回答说：哦，哪里啊！（不！），这当然有帮助了。事实上，很有帮助！
如果你选C，则表示：对，确实是一点帮助都没有。B和D是认为，没有什么帮助，但安慰对方，不必感到内疚。（B。没关系。D。别放心上）。
