68.He found it increasingly difficult to read, ______ his eyesight was beginning to fail.

A. and B. for C. but D. or

【答案】B。解析:此题考查原因状语从句。“his eyesight was beginning to fail”是“he found it increasingly difficult to read”的原因,因此本题应选用可以表示原因的连词for引导原因状语从句。故选B。

69. If it ______ for his invitation the other day, I should not be here now.

A. had not been B. should not be C.were not to be D.should not have been

【答案】A。该句是错综时间虚拟条件句。主句“I should not be here now.”表达的是与现在事实相反的情况;意为:现在我就不会在这里了;而根据if从句中表示过去的时间状语“the other day前些日子”可知,此处表达的应该是与过去事实相反的情况,所以要使用过去完成时;故选A。

70.It ______ Mike and Mary who helped the old man several days ago.

A. was B. are C. were D. had been

【答案】A。解析:本题考查的是强调句式。强调句式由“It is/was + 被强调成分+that/who…”构成。由于句中的动作是发生在过去,故选A。
