Answer 1

【答案】stayed；it；importance；to do；helps；creative；a；correctly；at；that/which
【解析】本文谈论睡眠的作用。
（1）stayed考查完成时态。根据前面 “Have you ever”可知，这里表示现在完成时，所以动词应用过去分词，故填stayed。
（2）it考查形式主语。It在这里表示形式主语，指代前面的“you”，故填it。
（3）importance考查名词。And前后连词的词性相同，根据前面“skill”可知，是名词，所以后面也应该接名词，故填importance。
（4）to do考查短语。“be able to do”意为“能够去做某事”，是固定用法，故填to do。
（5）helps 考查动词。前面的主语“sleep”是不可数名词，表示睡眠，后面的动词应该接第三人称单数形式，故填helps。
（6）creative考查形容词。“creative”在这里作表语，用于形容后面的名词“thinking”，故填creative。
（7）a考查冠词。Answer是不及物动词，后面接名词的时候中间需要用冠词连词，这里表示泛指某一种数学问题，所以用a，故填a。
（8）correctly考查副词。“correctly”表示状语，用于形容动词“solved”，起到强调作用，这里表示很准确的解决了问题，故填correctly。
（9）at考查固定结构。“at night”意为“在晚上”，是固定用法，故填at。
（10）that/which考查定语从句。先行词是“information”，引导词在从句中不作成分，故填that/which。
