A．enough good B．good enough C．enough well D．well enough 【答案】D 【详解】句意：——你觉得世界杯怎么样？——酷！我认为Leo Messi踢得足够好。他是最棒的。 考查词汇辨析及enough用法。good好，形容词；well好，副词。此处修饰动词played应用副词；enough修饰形容词或副词时，应后置。故选D。 2．—How old is your younger sister? —She is seven now. She will be ________ to go to school this September. A．enough old B．old enough C．young enough 【答案】B 【详解】句意：——你的小妹妹多大了？——她现在七岁了。今年九月份她就足够大可以去学校。 考查enough后置用法和形容词辨析。enough old错误表达；old enough足够大（年龄）； young enough足够年轻。根据“to go to school this September”可知，可以去上学，应该是年龄足够大，故选B。 3．The water in this village is not ________. A．enough clean to drink B．enough clean drinking C．clean enough to drink D．clean enough drinking 【答案】C 【详解】句意：这个村子的水不够干净，不能喝。 考查enough的用法。短语not enough to do sth意为“不够……以至于不能做某事”；enough作副词意为“足够地”，可修饰形容词和副词，但必须后置。故选C。 4．The classroom is not ________ for more than 40 students together. A．enough large B．large enough C．so large D．too large 【答案】B 【详解】句意：这间教室不够大，不能容纳40多名学生。 考查副词辨析和enough后置。so如此，常用于so…that句型；too太，常用于too…to句型，enough足够，修饰形容词时放在其后，表示主语所指的对象有足够的能力去做某件事，此处表示这间教室不够大，以致不能容纳40多名学生。故选B。 5．The boy didn’t do his homework ________, though he had ________. A．enough carefully, time enough B．careful enough, enough time C．carefully enough, enough time D．enough careful, time enough 【答案】C 【详解】句意：这个小男孩写作业不够细心，尽管他有足够的时间。 考查enough的用法以及副词的用法。enough修饰形容词或副词时需要后置；修饰名词时，enough放前放后均可。修饰动词短语“do his homework”应用副词carefully，故选C。 6．— What do you think of the film? — I think it’s _________ , but some people think it’s so _________. A．enough wonderful; bored B．wonderful enough; boring C．enough wonderful; boring D．wonderful enough; bored 【答案】B 【详解】句意：——你觉得这部电影怎么样？——我认为它足够精彩，但是有人认为它很无聊。 考查定语后置及形容词辨析。boring令人无聊的；bored感到无聊的。enough修饰形容词、副词时，放在形容词、副词后面，排除A和C；it指物，此处表示它是令人无聊的，用boring。故选B。 7．The book without any pictures is not ________ for children to read. Many children don’t like it. A．enough interesting B．interesting enough C．enough interested D．interested enough 【答案】B 【详解】句意：这本没有图片的书对孩子们来说不够有趣。许多孩子不喜欢它。 考查形容词辨析和enough后置。interesting有趣的；interested感兴趣的。此处修饰物“The book”，排除CD；enough修饰形容词应后置。故选B。 8．Our classroom is ________ to hold 51 students. A．enough big B．enough clean C．clean enough D．big enough 【答案】D 【详解】句意：我们的教室足够大到可以容纳51个学生。 考查形容词辨析和enough的用法。enough修饰形容词，要放在形容词的后面；根据“hold 51 students”可知，强调的是大而不是干净，所以填big enough。故选D。 9．The girl isn’t ________ to lift the heavy box. A．too strong B．strong enough C．so strong D．very strong 【答案】B 【详解】句意：这个女孩不够强壮，举不起这个重箱子。 考查副词用法。too strong太过强悍；strong enough足够强壮；so strong非常强壮；very strong非常强壮。根据“The girl isn’t...”可知，指的是这个女孩“不够强壮”，举不起这个重箱子。故选B。 10．The girls are ________ to look after themselves. A．too old B．old enough C．enough old D．young enough 【答案】B 【详解】句意：女孩们已经长大了，可以照顾自己了。 考查固定搭配和形容词辨析。too...to...“太……而不能……”；形容词+enough+to do sth.“足够……去做某事”；old“年纪大的”；young“年轻的”。根据“The girls are...to look after themselves.”可知，此处指女孩们已经足够大了可以照顾她们自己，old enough to look after themselves“足够大去照顾自己”，enough修饰形容词时需要放在形容词后面。故选B。 11．If you work ________, you will make a progress. A．enough hard B．hard enough C．enough hardly D．hardly enough 【答案】B 【详解】句意：如果你足够努力，你就会取得进步。 考查词义辨析及enough后置。hard努力地；hardly几乎不。此处指努力工作，故用hard修饰动词work。enough修饰形容词或副词，应后置。故选B。 12．The goal-keeper acted __________ to catch the ball. A．enough quickly B．so quickly C．quickly enough D．such quickly 【答案】C 【详解】句意：守门员动作够快，接住了球。 考查enough。enough“足够的”修饰副词要后置，排除A；such修饰名词，quickly是副词，排除D；so+形容词+that从句，是固定句型，该句子结构不符合；故选C。 13．Mr. Wu is ________ to spend a lot of time explaining things for us. A．very much patient B．enough patient C．patient very much D．patient enough 【答案】D 【详解】句意：吴先生很有耐心，花了很多时间为我们解释事情。 考查enough的用法。very much“非常”通常用于修饰动词，故A、C选项可排除。当enough“足够的”修饰形容词时，应把enough放在形容词之后，故选D。 14．I don’t have ________. Are you ________ to help me buy some food? A．enough time; kind enough B．enough time; enough kind C．time enough; enough kind 【答案】A 【详解】句意：我没有足够的时间。请帮我们买一些食物好吗？ 考查enough的用法。enough作为限定词时，意为“足够的”，置于名词之前修饰名词，所以第一空使用enough time；enough作为副词时，意为“足够地”，修饰形容词时，需要置于形容词之后，所以第二空使用kind enough。故选A。 15．The lift is ________ hold 15 people. A．enough big B．enough big to C．big enough D．big enough to 【答案】D 【详解】句意：这个电梯够容纳15人那么大。 考查enough位置。enough修饰形容词、副词时，要放在被修饰词之后。排除A/B选项，此处是“形容词+enough to do sth”的结构，故选D。 16．As a Grade 9 student, it’s not ________ to be hard-working. You have to try your best. A．too late B．late enough C．too good D．good enough 【答案】D 【详解】句意：作为一名九年级的学生，勤奋还不够好。你必须尽自己最大的努力。 考查固定句式。too late太晚；late enough足够晚；too good太好；good enough足够好；固定句式：too...to do sth...太而不能做某事；adj.+enough to do sth.足够……去做某事。根据“你必须尽自己最大的努力”可推测，空处表达“光是勤奋还不够好”。故选D。 17．His son isn’t ________ to plan everything well. A．careful enough B．enough careful C．enough carefully D．carefully enough 【答案】A 【详解】句意：他的儿子不够细心，没法把所有事情都规划好。 考查副词和形容词用法。enough足够地；careful细心的，形容词；carefully细心地，副词。根据“His son isn’t…”可知，此处作表语，需要用形容词；enough作副词修饰形容词时，需要放在所修饰词之后。故选A。 18．—Why do you recommend Sandy to be a volunteer for the meeting? —She is ________ to notice small changes around her and ready to give help in need. A．too careful B．careful enough C．too careless D．careless enough 【答案】B 【详解】句意：——你为什么推荐桑迪成为会议志愿者？——她足够细心，能注意到周围的小变化，并随时准备在需要时给予帮助。 考查形容词和副词用法。too careful太仔细；careful enough足够细心；too careless太粗心；careless enough足够粗心。根据“She is…to notice small changes around her and ready to give help in need.”可知，此处指她足够细心，能注意到周围的小变化，enough+形容词+to do sth.“足够……去做某事”，应用careful enough。故选B。 19．At the Rice Noodle Festival, different kinds of rice noodles are ________ to let you have a bite of Yunnan’s special tastes from many different places. A．so rich B．too rich C．rich enough D．enough rich 【答案】C 【详解】句意：在米线节上，不同种类的米线丰富到足以让你品尝到来自许多不同地方的云南特色风味。 考查enough后置。so rich如此丰富，通常需要搭配that从句；too rich太丰富，后跟动词不定式表示“太丰富而不能”；rich enough足够丰富，后跟动词不定式表示“足够丰富以至于”；enough rich错误表达。根据“different kinds of rice noodles are ... to let you have a bite of Yunnan’s special tastes from many different places.”可知，此处表示不同种类的米线足够丰富，让你能品尝到来自许多不同地方的云南特色风味，空后是动词不定式，用rich enough。故选C。 20．—Do you think we students can use the Chinese AI Model DeepSeek easily? —Certainly! It is ________ for us to learn to use. A．too easy B．easy enough C．too difficult D．difficult enough 【答案】B 【详解】句意：——你认为我们学生可以轻松使用中国人工智能模型Deepseek吗？——当然！它对我们来说很容易学会使用。 考查enough用法和形容词辨析。too easy太容易；easy enough足够容易；too difficult太困难，difficult enough足够困难。too...to do“太……而不能做某事”，enough to do“足够做某事”；根据“Certainly!”可知，说话者认为学习使用Deepseek足够容易。故选B。 二、完成句子(本大题共10小题，每小题2分，共20分) 21．The problem is too difficult for me to work out. (改为同义句) The problem isn’t me to work out. 【答案】 easy enough for 【详解】句意：对于我来说这个问题太难了以致于我不能解出来。too...for sb.to do sth.“对于某人来说太……而不能做某事”，同义结构为be+not+adj.+ enough for sb. to do sth.“对于某人来说不是足够……做某事”，其形容词和“too...to”结构中的形容词应是反义词，difficult的反义词为easy。故填easy；enough；for。 22．He is too young to attend school. （改为同义句） He is attend school. 【答案】 not old enough to 【详解】句意：他太小了，还不能上学。too...to...表示“太……而不能”，可用be not+adj+enough+to do sth结构进行替换，故填not；old；enough；to。 23．汤姆太害羞了而不敢在别人面前演讲。 Tom is too give a speech . 【答案】 shy to in public 【详解】“太……而不能……”too+adj.+to do；“害羞”shy，形容词；“在别人面前演讲”也就是“当众演讲”，用in public表示“当众”，固定短语，在句中作状语。故填shy；to；in；public。 24．他说得太快，不能清楚地表达自己的想法。 He speaks fast his ideas clearly. 【答案】 too to express 【详解】too…to…“太……而不能……”，express“表达”，to后用动词原形。故填too；to；express。 25．His brother is so short that he can’t reach the apple on the tree. (改为同义句) His brother isn’t to reach the apple on the tree. 【答案】 tall enough 【详解】句意：他如此矮以至于它够不到树上的苹果。“so short that”可以转化为not+形容词+enough to do sth“去做……是不够……的”，故第一空填写short的反义词“tall”。tall“高的”，tall enough“足够高”故第二空填写enough。故填tall；enough。 26．成年熊猫足够强壮，能够独自居住。 Adult pandas are on their own. 【答案】 strong enough to live 【详解】be strong enough to do sth“足够强壮去做某事”，live“居住”。故填strong；enough；to；live。 27．Sarah六岁，足够大可以上学了。 Sarah is 6 years old and is to school. 【答案】 old enough to go 【详解】be old enough to do sth.“足够大去做某事”，go to school“去上学”，故填old；enough；to；go。 28．我们的国家已经足够强大去面对和解决各种难题。 Our country has been and deal with different problems. 【答案】 strong enough to face 【详解】根据题干可知，strong enough to do sth“足够强壮做某事”；face“面对”。故填strong；enough；to；face。 29．我不够高，够不着那幅画。 I’m not the picture. 【答案】tall enough to reach 【详解】tall“高的”；enough“足够”，修饰形容词需后置；reach“能伸到/够到”。tall enough表示“不够高”，本句用不定式表结果，故填tall enough to reach。 30．他的弟弟太小而不能去参军。 His brother is young join the army. = His brother is young he can’t join the army. =His brother is not old join the army. 【答案】 too to so that enough to 【详解】too+形容词+to do sth.“太……而不能”，相当于so+形容词+that+从句，表示“如此……以至于……”，还可以用形容词+enough+to do的形式，故填too；to；so；that；enough；to。 三、短文填空(本大题共20小题，每小题2分，共40分) 阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。 Some birthday customs are quite similar in many parts of the world—birthday candles, birthday games, and birthday cakes.
