一、选择题
1.B
解析:B
【解析】
【详解】
考查冠词。句意:据说,这座桥建于明朝。根据句子的语境,bridge是指具体某一座桥,属特指,故用the;某个朝代的前面要用the。故选B。
2.C
解析:C
【解析】
句意:你以前看过这部电影吗?嗯,我在一个圣诞节看过,但是不记得具体是哪一年了。the是定冠词,一般用于特指的名词前;a是不定冠词,一般用于泛指的,有后置定语的一般都用the。题中the film是特指这部电影,圣诞节是泛指的一个,故选C。
考点:考查定冠词the和不定冠词a的用法区别。
3.A
解析:A
【解析】
考查冠词。a big breakthrough一个大的突破;bring back to life使活泼, 使生动, 使苏醒,根据句意选A。
4.D
解析:D
【解析】
考察冠词用法,根据题意,你不认为奥巴马是一个成功人士吗?这里是泛指,用不定冠词。是的,我这样认为。他在美国深受大众欢迎。这里的大众指的是美国的大众,为特指,故用定冠词。所以选D。
5.C
解析:C
【解析】
【详解】
考查冠词词义辨析。句意:——你觉得关于盲人的故事怎么样?——它是如此鼓舞人心,以至于我不假思索想去阅读一下。指代“盲人”,英语中用“the+形容词”;“a+序数词”表示又一次,再一次。故选C。
6.D
解析:D
【解析】
【详解】
本题考查冠词。解题步骤:1.确定第一空:danger表示“一件危险的人或物”时,是可数名词,此处泛指“一件危险的事情”,应使用不定冠词a,从而排除A/C项;2.确定第二空:根据空前but we still feel we have可知,此处特指“改善环境的力量”,应使用定冠词the。句意:雾霾已经对我们的生活构成一大威胁,但是我们仍然觉得我们有能力改善环境。故选D。
7.C
解析:C
【详解】
句意:多有用的机器人啊!它可以帮助我们做危险的工作。
考查感叹句。句子中心词是单数名词robot,且句子是省略主谓的感叹句,符合结构“What+a/an+adj+单数名词+主谓!”,useful是辅音音素开头的单词,应用a修饰,故选C。
8.A
解析:A
【解析】
试题分析:句意:-吉刚才姆开车走了一小时。-他花了这么短的时间就完成了这么长的路!冠词作为一种虚词,只能和名词一起使用。英语中的冠词分为不定冠词和定冠词。不定冠词有两个,a 和 an。a用在辅音开头的单词前面;an用于以元音开头的单词前。不定冠词用在单数可数名词前面,表示这个人或事物是泛指的不确定的一个,相当于中文的“一个”。定冠词和名词连用,表示某个或某些特定的人或东西。所以选A。
考点:考查冠词。
9.A
解析:A
【详解】
句意:——这台新电脑是你妈妈送给你的生日礼物吗? ——是的。我从没见过比这更好的。
考查冠词。a/an不定冠词,表泛指;the定冠词,表特指;第一个空后的 new computer被“your mother gave you as your birthday present”限定,因此,此处的新电脑表示特指,用定冠词the;第二个空是:否定词+比较级,表示最高级。故选A。
二、选择题
10.B
解析:B
【详解】
句意:我的父母养成了去玄武湖散步的习惯。
考查代词辨析。this这个,指近物;it它,没有远近之分;that那个,指远物;one一个,指代上文提到过的同类事物中的一个,但不是上文提到的那一个事物,如果指同类事物中的一些,要用ones;分析句子可知,句子使用固定结构: make it (形式宾语)+宾语补足语 (形容词/名词)+真正的宾语;make it a habit to do sth. 养成一个习惯做某事,这里的it指代的就是go out for a walk around Xuanwu Lake,所以此处使用代词it。故选B。
11.C
解析:C
【详解】
句意:当我在新西兰学习时,我妈妈试着为我做一些不同的菜。
考查不定代词和形容词的位置。something一些东西,一般用于肯定句及表示请求建议的疑问句中;anything也表示一些东西,用于否定句及疑问句中。题目所给的句子是一个肯定句,因此需用something,排除B/D;当形容词修饰不定代词时,要后置。故选C。

15.D
解析:D
【详解】
句意:对不起,这里不允许抽烟。如果你一定要抽的话,你会被按规定罚款的。
考查情态动词辨析。can能、会;will将要;may可以;must必须、一定。根据主句“you will be fined according to the rules.”可知,应是如果你一定要抽的话。故选D。
六、选择题
16.A
解析:A
【详解】
句意:我们在初中度过了多么快乐的时光!
考查感叹句。感叹句的结构:What+形容词+不可数名词+主语+谓语!What a/an+形容词+单数可数名词+主语+谓语!How+形容词/副词+主语+谓语!此处fun是不可数名词,因此用what修饰,故选A。

考查条件状语从句的时态和语态。will invite一般将来时;invite一般现在时;will be invited一般将来时的被动语态;am invited一般现在时的被动语态。根据主句“I will go with you”可知,if引导的条件状语从句应用一般现在时表示将来;又根据从句主语和动词之间是动宾关系,故从句应用一般现在时的被动语态,构成形式为be done;主语“I”是第一人称,助动词应用am;invite的过去分词是invited。故选D。
18.B
解析:B
【详解】
句意:除非对方要求,否则不要和他讨论这个问题。
考查一般现在时的被动语态。ask问,要求,是一个动词。根据句意“Don’t discuss the problem with your partner”可知,这里是建议不要和同伴讨论这个问题,由此可知unless从句中的主语“you”和ask是被动关系,即“你被要求去讨论”,应用被动语态。unless引导条件状语从句,从句中应用一般现在时态,故选B。
八、选择题
19.B
解析:B
【详解】
句意:乔,替我接电话。我正在厨房学习如何包饺子。
考查动词时态。“我”正在厨房学习如何包饺子,没时间接电话,所以请求乔帮忙接电话;某一时刻正在做某事,应为进行时态。故选B。

【详解】
句意:——快点,玛丽,电影已经开始十分钟了。——等一下。我在商店里买一些零食。
