A．watched; heard B．was watching; heard C．watched; was hearing D．was watching; was hearing 【答案】B 【详解】句意：昨晚我父亲正在看电视时，突然听到花园里传来一声巨响。 “when”引导的时间状语从句中，主句表示过去正在进行的动作（看电视），用过去进行时“was watching”；从句表示过去发生的短暂动作（听到声音），用一般过去时“heard”。 33．—What were your parents doing ________ you left home this morning? —My mother was sweeping the floor ________ my father was doing the dishes. A．while; when B．when; while C．when; since D．while; while 【答案】B 【详解】句意：——今天早上你离开家的时候，你的父母正在做什么？——我妈妈正在扫地，而我爸爸正在洗碗。 when和while都有“当……时候”的意思，when引导的从句谓语动词可以是延续性动词，也可以是非延续性动词，while引导的从句谓语动词必须是延续性动词，且强调主从句两个动作同时发生；since表示“自从……以来”。根据语境可知，第一个空，表示“当……时候”，且从句中的left为非延续性动词，因此用when引导；第二个空，表示两个动作同时发生，且从句中的“was doing the dishes.”为延续性动词，因此用while引导。所以应填when；while。 34．—________ you staying at home when the tsunami came? —No, I ________. I was training with my friends in a gym. A．Are; am not B．Were; am not C．Were; wasn’t D．Did; didn’t 【答案】C 【详解】句意：——海啸来的时候你待在家里吗？——不，我没有。我当时正在健身房和朋友训练。 “when the tsunami came”和“I was training with my friends in a gym.”提示时态为过去进行时。问句主语you搭配Were；答句主语I搭配was，否定形式为 wasn’t。 35．The naughty children nearly ________ while they ________ snowmen in the yard. A．fell over; were making B．fell down; made C．fell off; were making D．fell into; making 【答案】A 【详解】句意：淘气的孩子们在院子里堆雪人时差点摔倒。 fell over摔倒；fell down跌倒；fell off从……上掉落；fell into陷入。while引导时间状语从句时，表示主句动作发生在从句动作正在进行的过程中，因此主句用一般过去时，从句用过去进行时，结构为“was/were+doing”；此处表示孩子们堆雪人时差点摔倒，fell over符合语境。 36．—What ________ you ________ when the power went out in the classroom just now? —I ________ notes carefully with my deskmate. A．do; do; took B．were; doing; was taking C．did; do; was taking D．are; doing; took 【答案】B 【详解】句意：——刚才教室里停电的时候你正在做什么？——我正在和同桌认真记笔记。 根据“when the power went out in the classroom just now”可知，此句是描述过去某一时刻正在发生的事情，所以问句和答句都要用过去进行时，其结构是“was/were+动词现在分词”，问句主语是“you”，be动词用were，答句主语是“I”，be动词用was。因此第一空填were，第二空填doing，第三空填was taking。 37．While my father ________ the emergency generator, my mother ________ the children into the basement at that moment. A．checked; was leading B．was checking; led C．was checking; was leading D．checked; led 【答案】C 【详解】句意：当我父亲正在检查应急发电机时，我母亲正带领孩子们进入地下室。 while引导时间状语从句，表示两个动作在过去同时正在进行，此处两个动作可持续进行，因而用过去进行时“was/were+动词现在分词”，主从句主语都是第三人称单数，be动词用was。 38．I ________ my homework when the telephone ________ last night. A．did; rang B．was doing; was ringing C．did; was ringing D．was doing; rang 【答案】D 【详解】句意：昨晚电话响的时候我正在做作业。 当电话响这个动作发生时，做作业这个动作正在进行，所以前一个空应该用过去进行时“was doing”，后一个空强调电话铃响这个瞬间动作，用一般过去时“rang”。 39．It ________ heavily all day, so we had to stay inside. A．rained B．was raining C．rains D．is raining 【答案】B 【详解】句意：雨下了一整天，所以我们不得不待在室内。 考查动词时态。rained下过雨（过去式）；was raining过去一段时间一直在下雨/当时正在下雨（过去进行时）；rains下雨（第三人称单数现在时）；is raining现在正在下雨（现在进行时）。根据“It...heavily all day, so we had to stay inside.”可知，雨下了一整天，描述的是过去段时间一直持续的动作，应用过去进行时。故选B。 40．—What do you think of the movie last night? —When I got there it ______, so I only watched the end. A．finished B．had finished C．was finishing D．has finished 【答案】C 【详解】句意：——你觉得昨晚的电影怎么样?——当我到达的时候它快要结束了，所以我只看了结尾。 考查动词时态。根据“so I only watched the end.”我只看了结尾，可知电影快结束了，还没有结束，用过去进行时代替过去将来时，故选C。 12 同步新教材，周周有练习，月月有重点！ 11 同步新教材，周周有练习，月月有重点！ 学科网（北京）股份有限公司 $
