1.I (was having) my breakfast when the morning post came.
选项：A was having
解析：
1）be doing sth.when 表示“某人正做某事,就在这时候出现了另一件瞬间发生的事”,此处的 when 相当于并列连词的作用,意思是 and at that time.
2）从 when 引导的句子中的时态可知,这里指的是过去的事情,因此只能用过去进行时态.
2.“Did you check your paper?” “No,I (am checking) it now.”
选项：C am checking
解析：问话中用的是过去时态,指的是说话前有没有检查过论文.答话者回答的 No 意思是那个时候没有检查,然后进一步补充说明现在正在检查.
3.It (had been rainning) for a week and the streets were flooded.
选项：D had been raining
解析：
1) 从下文 the streets were flooded 可知这件事情发生在过去.
2）had been raining 是过去完成进行时,意思指雨是从过去的过去开始没完没了地下,一直下到到树木被淹没还没有停止.
4.He (was always sleeping) with his windows open.
选项：C was sleeping
解析：always 用在进行时态中带有责备或赞扬口气.这个句子可能表示下面的两种语气：
1) 责备：他总是开着窗户睡觉,真拿他没办法.
2) 称道：他有一副好身板,总是开着窗户睡觉,真羡慕他呀.
5.He hardly ever（makes) a mistake when he writes.
选项：B makes
解析：
1）下文 when he writes 提示本句指的是当前通常发生的事,因此时态应该定格在现在时态.
2）本句话的意思是“他写东西的时候几乎从来没有出过一个错误”.
