Answer 1

【答案】stayed；it；importance；to do；helps；creative；a；correctly；at；that/which
【解析】①stayed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。
②it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。
③importance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importanc e。
④to 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。
⑤helps 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。
⑥creative 考查形容词。“creative”在这里作表语，用于形容词后面的名词“thinking”故填creative。
⑦a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，这里表示反之某一种数学问题，所以用a，故填a。
⑧correctly考查副词。“correctly”表示状语，用于形容动词“solved”，起到强调作用，这里表示很准确地解决了问题，故填correctly。
⑨at考查固定短语。“at night”意为“在晚上”，是固定用语，故填at。
⑩that/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。
