Answer 1

答案：
18．will be held    考查时态及语态   根据句中的时间状语"next Thursday"可知，此处表示下周四将要发生的动作，故用一般将来时；由于主语The exam与动词hold构成被动关系，所以此处应使用一般将来时态的被动语态；故用will be held．   
19．which    考查关系代词    本句为非限定性定语从句；由于先行词essays（作文）指物，在该从句作主语；故用关系代词which．        
20．what  考查连接代词   此处用在动词短语 go over之后，引导宾语从句；由于该从句中缺少宾语，意为：…的（知识）；故用连接代词what．
21．as well as    考查句意理解以及连词    本句的意思是：更确切地说，我的意思是，你不但应该复习所有你更正过的试卷与你的课堂笔记，而且还应复习课本上的知识；此处用来连接并列宾语，意为：不但…而且…；故用连词as well as．
22．to ask    考查固定短语   hesitate to do sth．意为：犹豫/迟疑地做某事；故用to ask．
