5. This is the hotel _th__a_t/_w__h_ic_h_ we visited last year. 6. This is the hotel _w_h__e_re_ Lincoln once lived.
认识先行词和连接词
Could you still remember the time that/which we spent together ? 先行词是time,从句中缺spent“度过”的宾语，when只能做从句的时 间状语，所以用关系代词that/which做从句的宾语。
答题技巧
• 1. 确定定语从句的位置，即不完整的部分就是从句。 • 2. 找出先行词，是指人还是指物。 • 3.划分从句的句子成分，即划分主谓宾。 • 4. 根据2、3两条确定关系词。
