1 John and I _____ friends for eight years 。we first got to know each other at a christmas party。But we____ each other a couple of times before that 。
A had been :have seen B have been: have seen C had been :had seen D have been:had seen 答案：D 译文：约翰和我成为朋友有8年了。我们起初是在一个圣诞节晚会上彼此了解的。
但我们在此前曾经见过几次面。 解析：第一空，有for eight years 一段时间确定用现在完成时态，第二空是在christmas party前就已经见过面，christmas party是过去的一个时间过去的过去用过去完成时态。 2 All morring as she waited for the medical report from the doctor,he nervousness____。
A has grown B is growing C grew D had grown 答案：C 译文：整个早上她在等医生的医疗报告的同时，紧张的情绪也随之而增。 解析：由waited可以看出应该用过去时，这里并没有体现过去的过去，而是与此同时，所以选C适合。
