答案和解析
61.stayed 考查时态.此处是现在完成时态,stay的过去分词是stayed.
62.it 考查it用法.it作形式宾语,真正的宾语是动词不定式短语to think clearly the next day.
63.importance 考查名词."of+抽象名词"构成的短语相当于该抽象名词的同根形容词,即of great important=very important.
64.to do 考查动词不定式.be able to意为"能,会",后接动词原形.
65.helps 考查主谓一致.本文讲述的是一般事实,用一般现在时态,因主语sleep是单数三人称形式,谓语动词用单数三人称形式.
66.creative 考查形容词.thinking是名词,其前用形容词作定语.
67.a 考查冠词.problem是可数名词,其前用不定冠词a表示泛指.
68.correctly 考查副词.solve是动词,用副词修饰.
69.at 考查介词.at night意为"在夜里",是固定搭配.
70.that/which 考查定语从句.分析句子结构可知这是一个定语从句,先行词information在从句中作宾语,用关系代词that/which.
