【解析】

【详解】

【答案】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。

【名师点睛】

考查冠词。冠词是高考英语中的难点和重点,考生在冠词试题上失分较多,主要是缺乏语感,对一些知识点掌握不够透彻。本题中首先根据Beethoven排除选项B,因为不定冠词an用于以元音音素开头的单词前。通常情况下人名前是不加冠词的,但是如果指一个像某个名人的人时,在这个人名前加不定冠词。

20.I knew ________ John Lennon,but not ________ famous one.

A./;a B.a;the

C./;the D.the;a

【答案】B

a John Lennon一个叫做John Lennon的人,表泛指;第二空表特指。

高考英语真题分项详解名词和冠词解析版

专题10 名词和冠词 【2020年】 1.(2020·新课标I卷)The far side of the moon is of particular 64 (interesting) to scientists because it has a lot of deep craters (环形山),more so than the familiar near side. 【答案】interest 【解析】考查名词。句意:月球背面让科学家尤其感兴趣。根据空前的形容词particular可知,空处应填名词,interest是不可数名词,be of interest to sb.意为“(某物)使某人感兴趣”。故填interest。 2.(2020·新课标I卷)Next I broke the eggs into a bowl and beat them quickly with chopstick. 【答案】将chopstick改为chopsticks 【解析】考查名词复数。句意:下一步我把鸡蛋打到一个碗里,然后用筷子快速搅拌。chopstick是可数名词,意为“筷子”,通常以复数形式出现,故将chopstick改为chopsticks。 3.(2020·新课标II卷)Chinese New Year is a 61 (celebrate) marking the end of the winter season and the beginning of spring. 【答案】celebration 【解析】考查名词。句意:中国新年是一个庆祝冬天的结束和春天的开始。不定冠词a后接名词形式。故填celebration。 4.(2020·新课标II卷)Luckily,I will go home in two weeks for summer vacations. 【答案】将vacations改为vacation 【解析】考查不可数名词。句意:幸运的是,两周后我就要回家过暑假。分析句子,vacation译为“假期”是个不可数名词,后面不可加s表示复数。Summer vacation 译为“暑期”是固定搭配。故将vacations改为vacation。 5.(2020·新课标III卷)Filled with 64.(curious),the artist packed his bags and left. 【答案】curiosity 【解析】考查名词。句意:怀着好奇心,艺术家收拾行囊离开了。with为介词,后跟名词curiosity作宾语,表示“好奇心”。故填curiosity。 6. (2020·江苏卷)The health security systems of many countries are undergoing considerable ______. A. reservation B. transformation C. distinction D. submission 【答案】B 【解析】考查名词词义辨析。句意:许多国家的卫生安全系统正在经历重大变革。A. reservation预订;

【英语】高考英语冠词练习题及答案 一、单项选择冠词 1.In _______ gesture to help preserve history, the locals are repairing _______ large percentage of the historic sites steadily. A.the; the B.a; a C.the; a D./; the 【答案】B 【解析】 考查固定短语和冠词。句意“为了保护历史,当地居民正在修复一大批历史古迹。”in a gesture to do sth.“为了做某事”,是固定搭配;排除A、C;泛指一大批用a large percentage of...。故选B。 2.“Long time no see” is _____ sort of informal, but it is part of _____ language that Americans use daily. A.the; a B.a; the C.不填;the D.a; a 【答案】C 【解析】 考查冠词的用法。第一空考查短语:sort of 几分,有点,所以前不加冠词,第二空是特指,后面有定语从句修饰,所以先行词前需加the。因此答案选C。 3.—What about _____ job? —It’s too difficult _____ job for me. A.the; a B.the; the C.a; the D.a; a 【答案】A 【解析】 试题分析:考查冠词。本句第一句使用定冠词the表示特指那份工作;第二空使用a泛指一份工作。句意:—那份工作怎么样?—对我来说这是一份太难的工作啊!冠词的考查集中在定冠词the表示特指;不定冠词a/an表示泛指。另外要注意一些固定搭配中冠词的使用。特别注意抽象名词具体化的用法,如honor,success,failure,surprise,pleasure等名词抽象名词具体化的用法。故A正确。 考点:考查冠词 4.Mrs. Taylor has______ 8-year-old daughter who has_____ gift for painting --- she has won two national prizes. A.a; a B.an; the C.an; a D.the; a 【答案】C 【解析】 试题分析:考查冠词。泰勒有一个八岁的女儿,8的英语发音为eight,首字母发音为元音,应该用an修饰;have a gift for …有做、、、的天赋。故选C。 考点:考查冠词
