Answer 1

【答案】

【1】an

【2】without

【3】after

【4】of

【5】curiosity

【6】when

【7】called

【8】helpful

【9】it

【10】who

【解析】

试题分析：

【1】an 因excellent以元音音素开头，应用不定冠词an。

【2】without 根据前面说a college degree is not always necessary可知，此处填without，表示“没有”。

【3】after 表示一段时间之后应用介词after。

【4】of because of是复合介词，意为“因为”，后接名词或代词。

【5】curiosity 此处需用名词作主语，curious的名词形式是curiosity。

【6】when 此处表示时间，句意表示“当它们通常不会这样的时候”，用when引导时间状语从句。

【7】called this method与call存在被动关系，应用过去分词作定语。

【8】helpful very后应接help的形容词helpful，表示“有益的”。

【9】it it指代前一句提到的this method。

【10】who who用来引导定语从句，在从句中作主语，先行词是people。

【名师点拨】

不定冠词a和an的用法。a用在以元音音素开头的词前，表示“一”；an用在以辅音音素开头的词前，表示“一”。比如小题1，university这个词以辅音音素开头，所以前面加a，表示一所大学。an important meeting 一个重要的会议；an interesting story 一个有趣的故事；an old man 一位老人；an hour 一小时；an honest boy 一个诚实的男孩；an American lawyer一个美国的律师； a useful tool 一个有用的工具；a European friend一位欧洲的朋友。
