答案

86.class→classes
87.√ 
88.it→they
89.what→how
90.去掉the
91. Learned后加why
92.is→are
93.look前加to
94.learn改为learning
95. Practically改为practical

解析

86.class→classes此题考查名词的数。根据all of them可以确定class要用复数形式。 
87.√ 
88.it→they此题考查代词的用法。they指代classes。 
89.what→how此题考查从句的连接词的用法。what在宾语从句中作宾语，而这个句子中的谓语动词works是一个不及物动词，后面不接宾语。 
90.去掉rain前的定冠词the此题考查冠词的基本用法。rain在这里是泛指。
91. 在learned和it rained之间加why此题考查从句的连接词的用法。这句话的意思是“我知道了为什么下雨”。 
92.is→are此题考查主谓一致。这是一个存在句，在下行中的mysteries可知，要用系动词are。 
93.在mysteries和look into中间加to此题考查动词不定式的用法。to look into作mysteries的定语。 
94.Learn改为learning此题考查非谓语动词。在介词后要用动名词作宾语。
95.Practically改为practical此题考查形容词的用法。seemed是系动词，后接形容词作表语。
