Answer 1

答案：
解析：

1．class→classes　class作“课堂、班级”解时，是可数名词。这里用复数，表示泛指。 　　2．√ 　　3．it→they　those classes应该由复数代词替代。 　　4．what→how　works在此句中属不及物动词，不可用连接代词what作其宾语，只可用连接副词how作其状语。 　　5．去掉the　这里rain系泛指，故应删去定冠词。 　　6．it rained前加why　上文提到，下雨是一个奥秘。现在某节课上，我知道了它的奥秘，即知道了“为什么会下雨”。 　　7．is→are　there＋be句型的中主语是mysteries，所以谓语动词应用are。 　　8．look into前加to　这里需用动词不定式作定语，修饰mysteries。 　　9．learn→learning　动词作介词宾语，需用动名词形式。 　　10．practically→practical　seem在此句中作系动词用，故后应用形容词作其表语。
