　　A. made　 B. is making　 C. was making　 D. makes
　　答案C. 割伤手指是已发生的事情，应用过去时。同　时，when表时间的同时性，"玛丽在做衣服时"提供事情发生的背景，因此用过去进行时。
　　2) As she ___ the newspaper, Granny ___ asleep.
　　read； was falling　B. was reading； fell　C. was reading； was falling　D. read；fell
　　答案B.句中的as = when, while，意为"当……之时"。描述一件事发生的背景时，用过去进行；一个长动作发生的时候，另一个短动作发生。句意为 "在她看报纸时，奶奶睡着了。"句中的 fell (fall的过去时)，是系动词，后跟形容词，如：fall sick。
