Answer 1

【答案】

【1】stayed

【2】it

【3】importance

【4】to do

【5】helps

【6】creative

【7】a

【8】correctly

【9】at

【10】that/which

【解析】

【1】stayed考查完成時(shí)態(tài)。根據(jù)前面 “Have you ever”可知，這里表示現(xiàn)在完成時(shí)，所以動(dòng)詞應(yīng)用過去分詞，故填stayed。

【2】it考查形式主語。It在這里表示形式主語，指代前面的“you”，故填it。

【3】importance考查名詞。And前后連詞的詞性相同，根據(jù)前面“skill”可知，是名詞，所以后面也應(yīng)該接名詞，故填importance。

【4】to do考查短語。“be able to do”意為“能夠去做某事”，是固定用法，故填to do。

【5】helps 考查動(dòng)詞。前面的主語“sleep”是不可數(shù)名詞，表示睡眠，后面的動(dòng)詞應(yīng)該接第三人稱單數(shù)形式，故填helps。

【6】creative考查形容詞。“creative”在這里作表語，用于形容后面的名詞“thinking”，故填creative。

【7】a考查冠詞。Answer是不及物動(dòng)詞，后面接名詞的時(shí)候中間需要用冠詞連詞，這里表示泛指某一種數(shù)學(xué)問題，所以用a，故填a。

【8】correctly考查副詞。“correctly”表示狀語，用于形容動(dòng)詞“solved”，起到強(qiáng)調(diào)作用，這里表示很準(zhǔn)確的解決了問題，故填correctly。

【9】at考查固定結(jié)構(gòu)。“at night”意為“在晚上”，是固定用法，故填at。

【10】that/which考查定語從句。先行詞是“information”，引導(dǎo)詞在從句中不作成分，故填that/which。
