Harvesting has begun earlier than usual. 变成了How much earlier has harvesting begun? 不是从句成分要是陈述句的吗?怎么变了之后,有has,请老师们讲详细点,谢谢,学生基础很差。
Harvesting has begun earlier than usual.
How much earlier has harvesting begun?
哪来的从句?这是一般疑问句,has 提前了。语序没问题。
先不说语序问题,但就这个句子提问来看,这样提问“时间”,是不可以的:
How much earlier has harvesting begun? (误)
答语是什么呢?根据问句答语会是:
Harvesting has begun ten days earlier. 与原句不符,回不到原句的意思。
如果提问时间,就应该根据划线部分提问:
Harvesting has begun earlier than usual.
How early has harvesting begun? (正)
