Which film 三、用所给单词的正确形式填空 1．Miss Wu (teach) us English last term. 【答案】taught 【详解】句意：吴老师上学期教我们英语。根据时间状语“last term”提示，此处在描述过去发生的事，句子应用一般过去时，故动词teach应用过去式。故填taught。 2．I (learn) how to swim last summer vacation. 【答案】learned/learnt 【详解】句意：去年暑假我学会了如何游泳。由last summer vacation可知时态是一般过去时，动词用过去式。故填learned/learnt。 3．They (hear) a strange noise in the forest and felt scared. 【答案】heard 【详解】句意：他们在森林中听到了一个奇怪的声音，感到害怕。根据“They...a strange noise in the forest and felt scared.”和所给单词可知，时态为一般过去时，hear“听”，过去式为heard。故填heard。 4.We (see) some beautiful flowers in the park last weekend. 【答案】saw 【详解】句意：上周末我们在公园里看到一些漂亮的花。由last weekend可知时态是一般过去时，动词用过去式。故填saw。 5.If the bottle is (fill) with milk, take it away and don’t drink it at once. 【答案】filled 【详解】句意：如果瓶子里装满了牛奶，就拿走，不要马上喝。be filled with意为“装满”，固定词组。故填filled。 6.Although his parents with him, he still became an actor. (agree) 【答案】disagreed 【详解】句意：尽管他的父母不同意，他还是成为了一名演员。根据“Although his parents … with him, he still became an actor.”可知，前后两句表示转折，因此此处应表示不同意，disagree“不同意”，动词；根据“became”可知，句子为一般过去时，因此用disagreed。故填disagreed。 7.It took me about three hours (get) to Beijing by plane. 【答案】to get 【详解】句意：乘飞机到北京花了我大约三个小时。It takes sb. some time to do sth.“做某事花费某人多长时间”。空处填动词不定式。get“到达”，其不定式为to get。故填to get。 8.The man (drink) a lot of water after he walked for a long time. 【答案】drank 【详解】句意：这个男人在走了很长一段时间后喝了很多水。根据“he walked for a long time”可知句子时态为一般过去时，drink喝水，过去式为drank，故填drank。 9.Susan (ride) her bike to the park last Saturday morning. 【答案】rode 【详解】句意：苏珊上周六上午骑自行车去公园了。句中“last Saturday morning”表明句子时态是一般过去时，所填动词在句中作谓语，ride是动词原形，其过去式为rode。故填rode。 10.The work was tiring but I (enjoy) it. 【答案】enjoyed 【详解】句意：这项工作很累，但我享受它。根据句子的结构和时态“was tiring”（过去时），应使用过去式形式的动词enjoy。故填enjoyed。 四、单项选择 1. —Did you ______ any fruit yesterday? —Yes, I ______ some apples. A. buy; bought B. bought; buy C. buy; buy D. bought; bought 答案：A 解析：助动词“Did”后接动词原形，第一空用“buy”；答语时态与问句一致，用一般过去时，“buy”的过去式是“bought”。故填A。 2.—What did you do yesterday evening, Gina? —I ______ Titanic 3D in the City Cinema. A. watch B. watched C. am watching D. will watch 答案：B 解析：“yesterday evening”表明时态是一般过去时，“watch”的过去式是“watched”。故填B。 3. —Did you and your friend hear what the guide said in the park? —______. We were busy talking with each other at that time. A. Yes, we were B. No, we weren’t C. Yes, we did D. No, we didn’t 答案：D 解析：问句是以“Did”开头的一般疑问句，回答也用“did”；根据“忙着聊天”可知没听到，应作否定回答。故填D。 4. —__________ was your school trip? —It was great. A. What B. How C. Where D. When 答案：B 解析： 根据答语“It was great.”可知，问句是询问学校旅行怎么样，用how提问，故选B。 5.They __________ to the park and had a picnic yesterday. A. go B. goes C. went D. are going 答案：C 解析：  由“yesterday”可知句子时态为一般过去时，go的过去式是went，所以选C。 6.She used to __________ a lot of TV, but now she likes reading. A. watch B. watches C. watching D. watched 答案：A 解析：“used to do sth.”表示“过去常常做某事”，to后接动词原形，所以选A。 7. The teacher told us __________ down the new words. A. write B. to write C. writing D. wrote 答案：B 解析：“tell sb. to do sth.”表示“告诉某人做某事”，是固定搭配，所以选B。 8.—What did you do on the farm? —We __________ some strawberries and took them home. A. pick B. picks C. picked D. are picking 答案：C 解析： 问句是一般过去时，答句时态也应为一般过去时，pick的过去式是picked，选C。 9. —Where ______ you ______ your friends tomorrow? —At the park. A. do; meet B. are; meeting C. did; meet D. will; meeting 答案：B 解析：根据tomorrow可知，句子询问的是将来的动作。现在进行时可以表示按计划或安排即将发生的动作，其结构为be + 动词的现在分词。主语是you，be动词用are，meet的现在分词是meeting，所以用are meeting，B选项正确。A选项do; meet是一般现在时的疑问句形式；C选项did; meet是一般过去时的疑问句形式；D选项will后应接动词原形，will; meeting结构错误，所以A、C、D选项错误。 10.He didn't ______ his homework last night. A. does B. did C. do 答案：C 解析：一般过去时的否定句中，助动词didn't后接动词原形，所以用do，选C。 5、 完成句子 1. 上周我们学校组织了一次去博物馆的旅行。 Our school __________ __________ __________ __________ to the museum last week. 2. 起初，我觉得这个问题很难。 __________ __________ __________, I thought the problem was very difficult. 3. 请把这些书从桌子上拿走。 Please __________ these books __________ the desk. 4. 他过去常常在放学后打篮球。 He __________ __________ play basketball after school. 5. 她在聚会上玩得很开心，把作业忘得一干二净。 She __________ __________ __________ __________at the party and forgot all about her homework. 6.他们想出了一个帮助男孩的好办法。 They a good way to help the boy. 7.我同桌今天早上因为坐错了车迟到了。 My deskmate because he the wrong bus this morning. 8.杯子装满了果汁。 The glass is juice. 答案 1. went on a trip 解析 “go on a trip to...”表示“去……旅行”，根据“last week”可知，时态为一般过去时，go的过去式是went on a trip。 2. At the beginning 解析：“at the beginning”为固定短语，意为“起初，一开始” 。 3. remove; from 解析： “remove...from...”表示“把……从……移开/拿走”，please后接动词原形。 4. used to 解析：“used to do sth.”表示过去常常做某事 。 5. had a great time 解析： “have a great time”表示“玩得开心”，根据“forgot”可知，时态为一般过去时，have的过去式是had。 6.thought of 解析：根据中英文对照可知，此处缺少“想出”的英文表达。“想出”译为think of。又因为句子描述的是过去发生的事情，所以要用一般过去时，think的过去式是thought，故填thought；of 。 7. was late took 解析：“迟到”be late；“坐（车）”take。根据“this morning”可知用一般过去时，主语“My deskmate”是单数，其后用be动词was，take的过去式为took。故填was；late；took。 8. full/filled of/with 解析：根据中英文对照可知，英文句子应用短语be full of或be filled with表示“装满”，句中已有be动词is。故填full/filled；of/with。 题型一 完形填空 Dear Cindy, I’m writing to you from Sydney.
