70．难怪他今天没来上学，原来他生病了。 ________ ________ he didn’t come to school today. He is ill. 【答案】 No wonder 【详解】原句中“难怪”是关键词，表示“难怪”的短语是no wonder，它是“It’s no wonder that”的省略形式，引导主语从句，位于句首，首字母需大写。 71．令人惊讶的是，这个小女孩能背诵这么多古诗。 It is ________ that the little girl can recite so many ancient poems. 【答案】amazing 【详解】原句中的“令人惊讶的是”是关键词，“令人惊讶的是”译为amazing，形容词，此处作表语。 72．由于天正在下雨，我们不得不取消运动会。 ________ it is raining, we have to cancel the sports meeting. 【答案】As/Since 【详解】根据中英文对照可知，此处缺少“由于”。空格后“it is raining”是完整句子，需用引导原因状语从句的连词As或Since，二者均表示“由于、既然”，常用于句首。故填As/Since。 73．参加文化交流活动对于中学生来说是很重要的。 It’s important for middle school students to join in the ________ ________ activities. 【答案】 cultural exchange 【详解】原句中“文化交流”是关键词，此处用形容词cultural（文化的）作定语，修饰后面的名词成分，“交流”对应名词exchange，组合起来cultural exchange activities就是“文化交流活动”，符合句意。 74．We should stay away from buildings during an earthquake.（对画线部分提问） ________ ________ we do during an earthquake? 【答案】 What should 【详解】句意：地震期间我们应该远离建筑物。划线部分为“stay away from buildings”，意思是“远离建筑物”，表示具体的行为动作，对其提问用疑问词“what”来引导，表示“做什么”。原句中有情态动词“should”，在疑问句中应将“should”提到主语“we”之前，放在“what”之后。 75．我们在英语周活动中玩得很开心。 We ________ ________ ________ in the English Week activities. 【答案】 had great fun 【详解】原句中“玩得很开心”是关键词。根据英文句子结构可知，“玩得很开心”此处的英文表达是have great fun。因为句子描述的是过去发生的事情，所以要用一般过去时，have的过去式是had。 76．You should eat more vegetables to stay healthy. (改为同义句) ________ ________ eat more vegetables to stay healthy. 【答案】 You’d better 【详解】句意：你应该多吃蔬菜来保持健康。原句中should是情态动词，意为“应该”，表示建议。You’d better do sth.意为“你最好做某事”，也用于表达建议，可将原句中的You should替换为You’d better，故填You’d；better。 77．如果你发现油锅起火，不应该用水。   If you find a pan of hot oil on fire, you ________ use water. 【答案】shouldn’t 【详解】原文“不应该”是关键词，对应的单词是shouldn’t，情态动词。 78．你最好不要吃太多垃圾食品。 You ________ ________ ________ ________ too much junk food. 【答案】 had better not eat 【详解】原句中“最好不要”是关键词，“最好”是固定结构：had better ，否定形式是had better not。本句是一般现在时，had better没有人称变化，后跟动词原形，eat“吃”是动词。故填had；better；not；eat。 79．为了保持健康，你最好避免晚上熬夜。 To keep healthy, you’d better ________ ________ ________ ________ at night. 【答案】 avoid staying up late 【详解】原句中“避免晚上熬夜”是关键信息，表示“避免做某事”的短语是avoid doing sth.，“熬夜”是stay up late。本句中had better后接动词原形，因此avoid用原形；avoid后接动名词形式，stay用staying。 80．我们最好不要在教室里大声喧哗。 We ________ ________ ________ make a loud noise in the classroom. 【答案】 had better not 【详解】原句中“最好不要”为关键信息，对应固定搭配had better not do sth.。 81．过马路时，我们最好小心。 We ________ ________ ________ ________ when crossing the road. 【答案】 had better be careful 【详解】原句中“最好”和“小心”是关键词；表示“最好做某事”的固定搭配是had better do sth；表示“小心”的固定短语是be careful，had better后接动词原形。 82．你最好不要进入那个房间。 You ________ _________ _________ _______ the room. 【答案】 had better not enter 【详解】原句中“最好不要”和“进入”是关键词，表示“最好做某事”用had better do，否定形式为had better not do，后接动词原形。“进入”为英文enter，此处用动词原形。 83．她最好别用电话跟我保持联系。 She _______ ________ _______ ________ _______  _________ with me by phone. 【答案】 had better not keep in touch 【详解】原句中“最好别”、“保持联系”是关键词，had better not do sth“最好别做某事”，后接动词原形，固定搭配；keep in touch with sb “和某人保持联系”，动词短语。 84．他们最好能将这个短剧表演出来。 They _________ _________ __________ _______ the short play. 【答案】 had better act out 【详解】根据中英文对照可知，此处缺少“最好能将……表演出来”。“最好做某事”用固定搭配had better do sth.；“表演出来”用动词短语act out，且had better后接动词原形。 85．你最好把黑板上那些单词抄下来。 You ________ ________ ________ _________ the words on the blackboard. 【答案】 had better copy down 【详解】根据中英文对照可知，句子缺少“最好”和“抄下来”。“最好”可翻译为had better。空格后“the words”是名词短语，缺少谓语动词。动词短语“抄下来”：copy down。had better后接动词原形。故填had；better；copy；down。 86．杰克不应该从事教师工作。 Jack _____________ __________ _________a teacher. 【答案】 shouldn’t/should work/not as/be 【详解】原句中“不应该从事……工作”是关键词，“shouldn’t”表示“不应该”；“work as…”表示“从事……工作”，后面一般接表示职业、职务等名词。故填shouldn’t；work；as。 87．晚餐后你应该去散散步。 You _______ ________ ________ _______ _____ after dinner. 【答案】 ought/should to/go take/for a walk 【详解】原句中“应该去散散步”是关键词。表示“应该”的表达，常见的有“should”和“ought to”；表示“去散步”的短语常见的是“take a walk”和“go for a walk”。结合5个空，若选择“should”与“go for a walk”，“should”为情态动词，后接动词原形“go”；若选择“ought to”与“take a walk”，“ought to”后接动词原形“take”。故填should；go；for；a；walk/ought；to；take；a；walk。 88．很多学生在公园里做游戏玩得很开心。 ________ ________ ________ students ________ ________ ________  ________ games in the park. 【答案】 A number of have great fun playing 【详解】原句中“很多”、“做游戏玩得开心”是关键词，表示“很多”的短语是“a number of”，“a”位于句首，应该用大写“A”；表示“玩得开心”的短语是“have great fun”，其中“great”为形容词修饰不可数名词“fun”，“have fun doing sth.”为固定句型，意为“做某事很开心”；表示“做游戏”的短语是play games，play应用动名词形式playing。故填A；number；of；have；great；fun；playing。 89．难怪他这么开心，同时他也学到了很多东西。 ________ ________ he is so happy, and he learns a lot ________ ________ ________ ________. 【答案】 No wonder at the same time 【详解】前两空：原句中“难怪”是关键词，表示“难怪”的短语是No wonder，在句中作状语。后四空：原句中“同时”是关键词，表示“同时”的介词短语是at the same time，在句中作时间状语。 90．我们的努力让这次演出圆满成功，所有人都对结果很满意。 Our hard work ________ the show ________ ________ ________, and everyone ________ ________ ________ the result. 【答案】 made a big/great/complete success was happy/satisfied with 【详解】根据句意，句子为一般过去时态。第一空意为“让”，应填made；第二至四空是名词短语，意为“圆满成功”，翻译为a big/great/complete success；第五至七空意为“对……满意”，英文为be happy/satisfied with。复合不定代词作主语当作单数。故填made；a；big/great/complete；success；was；happy/satisfied；with。 10 同步新教材，周周有练习，月月有重点！ 15 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 $ 2025-2026学年一线教师制作新教材英语同步精品系列资料，名师遴选！ 2025-2026学年一线教师制作新教材英语同步精品系列资料，名师遴选！ 学校:___________姓名：___________班级：___________考号：___________ Unit6 Learning by doing 单词短语句型语法进阶练90题 说明：此专题分三种题型，大家根据实际情况选择进行专项训练！ 一、单项选择 1．You ________ eat or drink in the library.
