1.would you have come to his help,had you been free?正常语序是if you had been free,would you have come to his help?显然这是对已发生过的、过去的事情的假设
所以答句中用一般过去式 i was ,非虚拟语气
2.该句相当于if you prepare for the worst in advance,you will not feel too sad if you fail.主句将来式,if 从句一般现在式,故选prepare原形
1A 意思是：不好意思，我已经被预订了（已经答应要帮别人了）用过去时
2A 这个是祈使句。所以用原型
1.被动语态（过去式：was/were+过去分词）
2.祈使句（动词用原形）
1.因为主句中用了现在完成时和过去完成时，表示事情的发生有共性，所以答句应该用一般过去时，也表示的是一种对别人的尊敬的含义
2.第二句是一个祈使句，句中的and以为“就会”，表示顺承的关系，如果选C ,就应该去掉and
1 但我当时有事，叙事过去某个时候发生的事情用一般过去时态。
2 and 是并列连词，在这里连接的是两个并列的句子。
-你本可以帮她的，你那时不忙，对吗？
-是的，我不忙。不过，我已经答应要帮别人了！
用was表示过去时间。
提前做好最坏的准备，这样你就不会在失败时太难过了。
这是祈使句，用一般时态
