A．tried; managed B．managed; managed C．tried; tried D．managed; tried 【答案】A 【详解】句意：——昨天我试图解出这道物理题但失败了。你呢？——在老师的帮助下，我成功解出来了。 考查动词辨析。tried试图；managed完成；根据第一空“but failed”可知动作未成功，用“tried”；第二空“with the help of my teacher”表明成功完成，用“managed”。故选A。 47．Before, I ________ short hair. Now, my hair ________ long. A．have; is B．had; was C．had; is D．had; has 【答案】C 【详解】句意：以前，我留着短发。现在，我的头发变长了。 考查动词时态。第一空：根据时间状语“Before”，可知动作发生在过去，应用一般过去时。“have”的过去式是“had”，因此第一空填“had”；第二空：根据时间状语“Now”，可知描述当前状态，应用一般现在时。句子主语“my hair”是不可数名词，视为单数，长是头发的属性，因此使用be动词，对应的be动词用“is”，故选C。 48．—Who cooked breakfast this morning? —My sister ______. She always gets up early. A．is B．was C．does D．did 【答案】D 【详解】句意：——今天早上谁做的早餐？——我姐姐做的。她总是起得很早。 考查动词时态。is是；was是(过去式)；does做(现在时)；did做(过去式)。根据问句“cooked”可知是过去时，答句需用过去时did替代cooked以避免重复。故选D。 49．________ you ________ your homework yesterday?
