直接引语变间接引语中的yesterday怎么变

Answer 1

白天就用yesterday夜晚就用last night。
时间状语的变化直接引语变间接引语时，有些时间状语根据情况也要相应的改动。
如：如将now改为then，将today 改为that day，将tonight改为that night改为，将yesterday改为the day before，将this month改为that month，将last week改为the week before，将three years ago改为three years before，将tomorrow改为the next day，将next year改为the next year，等等。
如：
1.He said， “I’m verybusy now。” 他说，“我现在很忙。”
→He said that he was very busy then。他说他当时很忙。
2.He said， “I want toleave today。” 他说，“他想今天离开。”
→He said that he wanted to leave that day。他说他想那天就离开。
3.He said， “She leftyesterday。” 他说，“她昨天离开了。”
→He said that she had left the day before。他说她前一天就离开了。
4.She said， “I’ll tellyou tomorrow。” 她说：“我明天告诉你。”
→She said that she would tell me the next day。她说她第二天告诉我。
