65．I can
【解析】句意：你能告诉我吗？我该如何处理这些问题？“How can I deal with all these problems ”是特殊疑问句，根据宾语从句要用陈述句语序，应变为“How I can deal with all these problems”。故填I；can。
66．he could
【解析】句意：“你怎样才能让你的记忆力更高效？”玛丽问她儿子。根据“Mary asked her son how”可知，句子变为间接引语时，实际就是改为how引导的宾语从句，故从句要用陈述语序，根据“his”可知，从句主语应为he，此处主句是一般过去时，从句也要要用一般过去时，can的过去式为could。故填he；could。
67．didn’t create
【解析】句意：他们在电影中创造了许多难忘的瞬间。此句是一般过去时的肯定句，变否定句时要借助于助动词did，否定是didn’t，didn’t后跟动词原形。故填didn’t create。
68．wonder whether you can
【解析】句意：你这周末能和我一起去购物吗？我想知道。空格处把一般疑问句Can you go shopping with me this weekend 改写为动词wonder的宾语从句，故用whether引导，同时“I”要变成“you”。故填wonder；whether； you； can。
69．shall we
【解析】句意：让我们成为更环保的人，好吗？Let’s开头的祈使句，其反意疑问句为shall we。故填shall we。
70．hasn’t it
【解析】句意：一切都变了，是吗？反意疑问句遵循“前肯后否，前否后肯”原则，前面为肯定含义，故后面反意疑问句用否定形式；本句时态为现在完成时，其助动词是has；当陈述部分主语是不定代词时，疑问部分主语用it代替。故填hasn’t it。
71．oughtn’t to
【解析】句意：你应该写信感谢她。ought to“应该”，为情态动词，变否定句直接在ought后加not，缩写为oughtn’t。故填oughtn’t；to。
72．instead of asking
【解析】句意：你最好骑自行车去学校。你最好不要求你的妈妈开车带你去学校。
根据两个句子的句意可知，“你最好是骑自行车去学校，而不是让妈妈开车带你去学校”。 句中“是……而不是……”，用instead of doing sth.来表达。故填instead；of；asking。
73．is taken care of
【解析】句意：我奶奶病了。我妈妈在家照顾她。原句改为被动语态，即奶奶被妈妈照顾，结构是be done。根据“takes”可知，时态是一般现在时，主语she是第三人称单数，故用be动词is，take用其过去分词形式。故填is；taken；care；of。
74．Are done
【解析】句意：学生们经常在课间做眼保健操。根据“do”可知，时态是一般现在时，改为被动语态的一般疑问句，主语eye exercises是复数，故将be动词are提前，置于句首，首字母大写，动词do用其过去分词形式。故填Are；done。
75．ought not
【解析】句意：你应该告诉她真相。ought to的否定形式为ought not to“不应该”。故填ought；not。
76．is not cleaned
【解析】句意：教室的窗户每天都擦。此句是含有be动词“is”的句子，变否定句需在“is”后加“not”即可，根据空格数可知“is”和“not”不用缩写，因此第一空填is；第二空填not；第三空填cleaned。故填is；not；cleaned。
77．is visited by
【解析】句意：每年都有许多外国人参观长城。被动语态的句子主语为“the Great Wall”，和谓语动词visit为被动关系，原句为一般现在时，应用一般现在时的被动语态“is/are done”，主语为单数，助动词用is，by后强调动作或行为的发出者，表示“被……”。故填is；visited；by。
78．Washing machines are made by the workers in that factory.
【解析】句意：这些工人们在工厂制造洗衣机。原句时态为一般现在时，所以改写后的句子使用一般现在时的被动语态（be done），将原来句子的宾语“washing machines”作为主语，主语是复数，因此be动词用“are”，动词“make”变为过去分词“made”；原句的主语“the workers”变为“by the workers”；地点状语“in that factory”不变，位于句末。故填Washing machines are made by the workers in that factory.
79．Lots of trees are planted along the streets by us every year./Lots of trees are planted along the streets every year./Every year lots of trees are planted along the streets by us./Every year lots of trees are planted along the streets.
【解析】句意：我们每年沿着街道种很多树。变为被动语态时，原句中的宾语“lots of trees”变为主语，表示复数，用are构成被动语态，谓语plant的过去分词为planted；地点状语“along the streets”置于谓语planted之后；原句中的主语“We”变为宾语，用宾格形式us，前面加介词by，意为“被”，时间状语every day可置于句末或句首。故填Lots of trees are planted along the streets by us every year./Lots of trees are planted along the streets every year./Every year lots of trees are planted along the streets by us./Every year lots of trees are planted along the streets.
80．Many vegetables are grown by farmers in the fields in spring.
【解析】句意：农民们春天在地里种了许多蔬菜。根据“Farmers”和“many vegetables”可知，变被动句时，原句的主语和宾语交换位置，宾语前加by，故“many vegetables”作主语，many的首字母m要大写，“Farmers”作宾语，首字母F要小写，其前加by，根据“grow”可知，被动语态句子中，谓语动词为“be+过去分词”，由“many vegetables”和“grow”可知，句子主语为复数，且时态为一般现在时，故应用be动词中的are，grow的过去分词为grown，句子余下结构照抄下来。故填Many vegetables are grown by farmers in the fields in spring。

参考答案及试题解析
1．Have yet
【解析】句意：科学家们刚刚在一份期刊上发表了他们具有开创性的研究成果。句子为现在完成时，改为一般疑问句需要助动词have提前，并大写首字母，而肯定句中的just在改为一般疑问句时，应改成yet并放在句尾，故填Have；yet。
2．Neither offers
【解析】句意：樱桃溪和查特菲尔德州立公园都提供允许狗不系绳的区域。改为否定句时，both...and...“……和……都”要变成neither...nor...“……和……都不”，句首首字母n要大写；neither...nor...遵循“就近原则”，即当neither...nor... 连接两个主语时，谓语动词的单复数形式需与nor 后的主语保持一致 ，nor后的主语“Chatfield State Park”表示单数，且时态是一般现在时，所以动词offer要变成第三人称单数形式offers。故填Neither；offers。

【解析】句意：尽管每个人都汗流浃背，但我们都感到很高兴，因为我们做得很好。根据“Everyone was in a sweat, but we felt happy.”可知，用although改写时需将although置于everyone之前，引导让步状语从句；用because扩写时需补充原因状语从句，说明高兴的原因是“做得很好”，符合原句中“虽然辛苦但内心满足”的逻辑。故填Although everyone was in a sweat, we all felt very happy because we had done a good job.
46．don’t plant
【解析】句意：他们每年种植不同种类的树。原句中的“plant”为实义动词，一般现在时否定句需要用don’t，后接动词原形。故填don’t；plant。
47．Did create
【解析】句意：我的宠物狗刚才把家里弄得一团糟。created是动词过去式，一般疑问句借助于助动词did，后面的动词用原形，故填Did；create。
48．hasn’t become

51．didn’t have
【解析】句意：他们昨天在公园野餐。改为否定句，had是实义动词，原句时态为一般过去时，所以否定句助动词用didn’t，其后加动词原形。故填didn’t；have。
52．Must we put
【解析】句意：我们必须把垃圾放进垃圾箱。分析句子可知，句子要改为一般疑问句，应该将情态动词Must提到句首，首字母大写；其他保持不变，主语是we“我们”；put“放”，作谓语动词。故填Must；we；put。
53．we can

58．can she
【解析】句意：我不相信她能解决这个问题。句子是宾语从句，主句结构是I don’t think...，此处疑问部分和从句保持一致，且此处是否定前移，故疑问句部分用肯定形式，用情态动词can，主语是she。故填can；she。
59．Can read
【解析】句意：通过读词组，我可以读得更快。原句为含有情态动词can的陈述句，变一般疑问句时，can提前， 后跟动词原形。故填Can；read。
60．don’t suppose can
【解析】句意：我想你能帮助我。此句是宾语从句，当宾语从句的主句主语是第一人称，谓语动词是think/suppose/believe时，需要否定前移，也就是在主句上否定。主语是I，需要使用助动词don’t，后加动词原形suppose；第三空填can。故填don’t；suppose；can。
61．can be taken
【解析】句意：你可以把书带回家。结合can可知，本句是含有情态动词的被动语态，结构为can be done。take的过去分词为taken。故填can be taken。

64．can it
【解析】句意：空气净化器很难清除大厅里难闻的气味。反意疑问句遵循“前肯后否，前否后肯”原则；hardly是否定词，句子应用前否后肯；疑问部分主语用代词it来代替The air cleaner。故填can；it。
65．I can
【解析】句意：你能告诉我吗？我该如何处理这些问题？“How can I deal with all these problems ”是特殊疑问句，根据宾语从句要用陈述句语序，应变为“How I can deal with all these problems”。故填I；can。
66．he could
【解析】句意：“你怎样才能让你的记忆力更高效？”玛丽问她儿子。根据“Mary asked her son how”可知，句子变为间接引语时，实际就是改为how引导的宾语从句，故从句要用陈述语序，根据“his”可知，从句主语应为he，此处主句是一般过去时，从句也要要用一般过去时，can的过去式为could。故填he；could。

71．oughtn’t to
【解析】句意：你应该写信感谢她。ought to“应该”，为情态动词，变否定句直接在ought后加not，缩写为oughtn’t。故填oughtn’t；to。
72．instead of asking
【解析】句意：你最好骑自行车去学校。你最好不要求你的妈妈开车带你去学校。
根据两个句子的句意可知，“你最好是骑自行车去学校，而不是让妈妈开车带你去学校”。 句中“是……而不是……”，用instead of doing sth.来表达。故填instead；of；asking。
73．is taken care of
【解析】句意：我奶奶病了。我妈妈在家照顾她。原句改为被动语态，即奶奶被妈妈照顾，结构是be done。根据“takes”可知，时态是一般现在时，主语she是第三人称单数，故用be动词is，take用其过去分词形式。故填is；taken；care；of。
74．Are done
【解析】句意：学生们经常在课间做眼保健操。根据“do”可知，时态是一般现在时，改为被动语态的一般疑问句，主语eye exercises是复数，故将be动词are提前，置于句首，首字母大写，动词do用其过去分词形式。故填Are；done。
75．ought not
【解析】句意：你应该告诉她真相。ought to的否定形式为ought not to“不应该”。故填ought；not。
76．is not cleaned
【解析】句意：教室的窗户每天都擦。此句是含有be动词“is”的句子，变否定句需在“is”后加“not”即可，根据空格数可知“is”和“not”不用缩写，因此第一空填is；第二空填not；第三空填cleaned。故填is；not；cleaned。
77．is visited by
【解析】句意：每年都有许多外国人参观长城。被动语态的句子主语为“the Great Wall”，和谓语动词visit为被动关系，原句为一般现在时，应用一般现在时的被动语态“is/are done”，主语为单数，助动词用is，by后强调动作或行为的发出者，表示“被……”。故填is；visited；by。
78．Washing machines are made by the workers in that factory.
【解析】句意：这些工人们在工厂制造洗衣机。原句时态为一般现在时，所以改写后的句子使用一般现在时的被动语态（be done），将原来句子的宾语“washing machines”作为主语，主语是复数，因此be动词用“are”，动词“make”变为过去分词“made”；原句的主语“the workers”变为“by the workers”；地点状语“in that factory”不变，位于句末。故填Washing machines are made by the workers in that factory.
79．Lots of trees are planted along the streets by us every year./Lots of trees are planted along the streets every year./Every year lots of trees are planted along the streets by us./Every year lots of trees are planted along the streets.
【解析】句意：我们每年沿着街道种很多树。变为被动语态时，原句中的宾语“lots of trees”变为主语，表示复数，用are构成被动语态，谓语plant的过去分词为planted；地点状语“along the streets”置于谓语planted之后；原句中的主语“We”变为宾语，用宾格形式us，前面加介词by，意为“被”，时间状语every day可置于句末或句首。故填Lots of trees are planted along the streets by us every year./Lots of trees are planted along the streets every year./Every year lots of trees are planted along the streets by us./Every year lots of trees are planted along the streets.
80．Many vegetables are grown by farmers in the fields in spring.
【解析】句意：农民们春天在地里种了许多蔬菜。根据“Farmers”和“many vegetables”可知，变被动句时，原句的主语和宾语交换位置，宾语前加by，故“many vegetables”作主语，many的首字母m要大写，“Farmers”作宾语，首字母F要小写，其前加by，根据“grow”可知，被动语态句子中，谓语动词为“be+过去分词”，由“many vegetables”和“grow”可知，句子主语为复数，且时态为一般现在时，故应用be动词中的are，grow的过去分词为grown，句子余下结构照抄下来。故填Many vegetables are grown by farmers in the fields in spring。
