such a/an+ 形容词+单数可数名词；such+形容词+不可数名词/可数名词复数。
boy 为可数名词单数形式，所以此处需要冠词修饰，泛指“一个”，排除C；honest ['ɒnɪst] 是以元音音素开头，前面用不定冠词an 修饰，排除A/D。
monitor of our class在句子中是插入语，解释说明Benny的身份，因此前面不用冠词。
故选B。
【点睛】不定冠词的用法不定冠词有两个，a 和 an。
a用在辅音音素开头的单词前面；an用于以元音音素开头的单词前。
如：a book, an apple。
1）不定冠词用在单数可数名词前表示“某一个”。
如：There is a policeman at the door.门口有个警察。
2) 不定冠词用在单数可数名词之前，表示“任何，每个”。
如：A car must be insured.汽车一定要上保险。
3) 不定冠词和名词连用作表语或同位语，主要说明某个人或东西所属类别。
如：She is a teacher. 她是个老师。
We all thought him a suitable person for the job.我们都认为他是适合做这个项目的人。
4）不定冠词用于某些固定短语中。
如：have a try试一下 take a break 休息一下 have a good time 玩得痛快make a living 谋生 as a matter of fact 事实上 in a word 总而言之2．C解析：C【解析】句意：——你父亲怎么啦？——他牙疼，所以他昨天去看牙医了。
have a toothache牙疼，故选C。
3．D解析：D【解析】句意：——树后面的那个女孩是谁？——哪一个？带伞的那个？根据Who is _____ girl behind the tree可知，在问句中这里特指树后面的女孩是谁，应使用定冠词the。
再根据The one with _____ umbrella可推测，此处泛指一把雨伞，表示“一个”，应用a/an。
又知a/an 的用法：a用于辅音音素开头的词前，an用于元音音素开头的词前，且umbrella/ʌmˈbrelə/是以元音音素开头的，所以此处应用an；故答案选D。
4．A解析：A【解析】句意：在英国上高中一年对我来说是一次激动人心的经历。
考查冠词辨析题。
a是不定冠词，泛指，一个，用于辅音因素开头的单数可数名词前；an不定冠词，泛指，一个，用于元音因素开头的单数可数名词前；the定冠词，特指，用在独一无二名词前，像地球，月亮，太阳。
前句中的high school（高中）是表示校名的专有名词，不需用冠词；后句中的exciting以元音音素开头，需用不定冠词an。
根据句意语境，可知选A。
5．A解析：A【解析】句意：电影《复仇者联盟3：无限战争》是如此令人兴奋，我想再次观看它。
