D faced with fierce pressure As they are

请确保您的答案是是对的，最好说下理由。

Answer 1

B was not ：could have avoided 虚拟语气，针对已经反生的事情，表示：本来能够避免但实际没能避免之意。所以实际情况是：当时不够小心.译文：jack原本能避免那个可怕的车祸，但是他当时不够小心。
D faced with fierce pressure As they are ：原句很显然需要有“虽然。。”的意思，才能和后面的进行转折。as表示虽然要倒装，倒装的形式之一是把系动词之后的表语部分提前，因此此句选D。如：虽然他很聪明，但这个题他不会：clever as he is, he can't understand this problem.
欢迎追问~~~

Answer 2

1D
这个是个虚拟语气，could have done表示与过去事实相反的情况，本可以做却没有
从句：If 主语+had+done 　　主句：主语+should/would/could/might+have done　
2 D
考察as结构引导状语从句，表"尽管"、"虽然",常用于倒装句式,引让步状从。倒装的时候把系动词后的部分提前
如：Old as he was, he still worked very hard. 他虽然年龄大了,但工作还很努力。
