A．How B．What a C．How a D．What 50．________ useful information the article has given us! A．What B．What a C．What an D．How 参考答案 1．C 【详解】句意：——莉莉在英语演讲比赛中得了一等奖！——这是多么令人兴奋的消息啊！ 考查感叹句。根据“... exciting news it is!”可知，该句是感叹句，感叹句的中心词“news”是不可数名词，故用“What+adj+不可数名词+主谓！”结构。故选C。 2．A 【详解】句意：但是情况已经变得多糟糕啊！我现在夜里几乎无法入睡。我该怎么办？ 考查感叹句。感叹句中，how修饰形容词或副词，what修饰名词。根据“But...terrible the situation has become!”可知，本句是感叹句，中心词为形容词terrible，所以需用how引导此感叹句，此感叹句的结构是“how+形容词+主语+谓语”。故选A。 3．D 【详解】句意：——多么精彩的派对啊！——是的。它如此精彩，以至于我永远都不会忘记。 考查感叹句的用法。感叹句常用“What”或“How”引导，结构分别为What+(a/an)+形容词+名词+主语+谓语；How+形容词/副词+主语+谓语。本句中“excellent”是形容词，后面直接接主语“the party”和谓语“was”，符合“How”引导感叹句的结构。故填D。 4．A 【详解】句意：看到这么多人来这里庆祝我的晋升，真是个大惊喜！ 考查感叹句的用法。根据“…surprise to see so many of you here to celebrate my promotion!”可知，此处对应的感叹句结构是：what+a/an+名词+主谓！故选A。 5．C 【详解】句意：这个男孩多么聪明啊！他能读数百首诗。 考查感叹句。感叹句的句式“what+不定冠词+形容词+单数可数名词+(主谓)”；“what+形容词+复数可数名词+(主谓)”；“what+形容词+不可数名词+(主谓)”；“How+形容词或副词+(主谓)”。本句空后为形容词smart，用how引导感叹句。故选C。 6．C 【详解】句意：你给我们发了多么鼓舞人心的信息啊！ 考查感叹句结构。此句的中心词是单数名词message，应该用感叹句结构“What a/an+形容词+名词单数+主语+谓语”，encouraging为元音音素开头，不定冠词用an。故选C。 7．B 【详解】句意：电影《浪浪山小妖怪》多么迷人啊！我想再看一遍。 考查感叹句。分析句子成分可知，fascinating“迷人的”为形容词，the film Nobody为主语，is为谓语，符合感叹句结构“How+形容词+主+谓”，故选B。 8．B 【详解】句意：——Lulu在比赛中跑了第一名。——她取得了多大的进步啊！她过去在跑步方面很弱。 考查感叹句和used to的用法。used to be曾经是；be used to doing sth.习惯于做某事。第一个空，progress是不可数名词，感叹句结构应用“What +形容词+不可数名词+主谓!”；根据“She…weak in running.”可知，表示过去的状态，用used to be。故选B。 9．A 【详解】句意：——看这张照片。长春人正玩得多开心啊！——哇！他们正在庆祝冰雪节。 考查感叹句。fun“乐趣”是不可数名词，感叹句中用what修饰名词，不能用a。故选A。 10．A 【详解】句意：你昨天给我的建议多么重要啊！我成功解决了问题。 考查感叹句的用法。空处所在句为感叹句，中心词advice是不可数名词，用what引导感叹句，结构为“What + 形容词 + 不可数名词 + 主语 + 谓语!”。故选A。 11．C 【详解】句意：在手机上收发电子邮件是多么方便啊！ 考查感叹句。What引导的感叹句，修饰的中心词是名词；How引导的感叹句，修饰的中心词是形容词或副词。分析句子结构可知，本句中心词是形容词convenient，所以用How引导感叹句，其结构为“How+形容词+主谓！”。故选C。 12．C 【详解】句意：你在学习上取得了多么大的进步啊！我要向你学习。 考查感叹句的用法。感叹句有what和how两种引导方式，what修饰名词短语，how修饰形容词或副词。progress是不可数名词，不能用不定冠词a/an修饰。great progress为名词短语，需用what引导，故选C。 13．A 【详解】句意：这些天上海的天气多好啊！ 考查感叹句。What用于修饰不可数名词；What a用于修饰可数名词单数，且冠词后的词需以辅音因素开头；How用于修饰形容词或副词；What an用于修饰可数名词单数，且冠词后的词需以元音因素开头。“weather”是不可数名词，需用“What”引导感叹句，结构为“What +形容词+不可数名词+主谓”。故选A。 14．B 【详解】句意：——现在山区的人们可以直接乘高速列车去北京了。——多么令人兴奋的消息啊！ 考查感叹句的用法。该句的中心词news是不可数名词，应用“What + 形容词 + 不可数名词！”的结构。故选B。 15．C 【详解】句意：——通过看电影学习英语是多么有用的方法啊！——是的，我也这么认为。 考查感叹句。感叹句中，what修饰名词短语，how修饰形容词或副词。此处“useful way”为单数名词短语，需添加不定冠词，“useful”以辅音音素开头，故用What a。故选C。 16．C 【详解】句意：多好的天气啊！我们可以去湖上划船了。 考查感叹句和形容词辨析。good好的；bad坏的，糟糕的。根据空格后“weather it is!”可知，weather是不可数名词，该感叹句结构为：“What + adj. + +不可数名词+主谓!”，表示“多么……的……啊”，故排除A、B选项；又根据后半句“We can go boating on the lake.”可知，天气好，故形容词用good。故选C。 17．A 【详解】句意：老师告诉我们的消息多么重要啊！ 考查感叹句。句子的中心词为不可数名词news，感叹句结构应用“What+形容词+不可数名词+主语+谓语！”选项B和C中的冠词an/a用于可数名词，错误；选项How后应直接跟形容词或副词，但本句中心词为名词，故错误。故选A。 18．A 【详解】句意：天气真糟糕！我们不能出去玩。 考查感叹句的用法。根据“bad weather it is!”可知，weather是不可数名词，前面不能用冠词a。此处应用What引导感叹句，其结构为“What+形容词+不可数名词+主语+谓语”。故选A。 19．B 【详解】句意：——现在，无人驾驶飞机在许多方面都很有用。——多么聪明的发明啊！ 考查感叹句。根据“…smart invention it

考查感叹句的用法。感叹句中，How用于修饰形容词、副词或动词，What用于修饰名词。本句中心词是副词“fast”，修饰动词flies，因此用How引导感叹句。故选B。 21．A 【详解】句意：技术发展得越来越快，给我们带来了很多便利。电脑是多么重要啊！ 考查感叹句的用法。此句为感叹句，且中心词为形容词“important”，符合结构为“How+形容词+主语+谓语!”的感叹句。故选A。 22．B 【详解】句意：关于北极熊的纪录片向我们展示了它们的生活环境现在有多么危险。 考查感叹句引导词。what用于修饰名词；how用于修饰形容词或副词；what a用于修饰可数名词单数；how a语法错误。空白处后为形容词dangerous，需用how修饰形容词表示程度。故选B。 23．A 【详解】句意：在高峰时间骑自行车是多么方便啊！ 考查感叹句。How如何，用于形容词前；What什么，用于名词前；What a用于单数可数名词；What an用于元音开头的单数可数名词。中心词convenient是形容词，感叹句结构为How+形容词+主语+谓语。本句中心词为形容词，故用How。故选A。 24．C 【详解】句意：这场比赛多么惊人啊！所有机器人都能跑得这么快。 考查感叹句。感叹句中，how用于修饰形容词或副词，what用于修饰名词。分析句子“…amazing the game was!”可知，本句中心词为形容词amazing，因此用how引导感叹句。故选C。 25．A 【详解】句意：——Jane在英语考试中得了满分。——她取得了多么大的进步啊！ 考查感叹句。What什么；What a多么一个；How怎样、如何、多么；How
