变为同义句为She didn't buy food。
同义句得运用所学的词汇、语法知识和句型结构填写句子,使句子结构完整、逻辑合理、语法知识无误、意思与所给句子相同。
用同义词或同义词组对原句中的某些词或词组进行替换,注意转换后的词或词组的词形变化要与句子其他成分相适应。如:
1. That day we could see flowers here and there.
That day we could see flowers __________.
答案:everywhere
解析:everywhere与here and there都表示“到处”。
用反义词或词组的否定式表达与原句相同的意思,主要考查学生对反义词(词组)的积累和换位思维的能力。如:
1. It’s clear that this visit is different from last time.
It’s clear that this visit is not the___ ___last time.
答案:same as
解析:be different from意为“与……不同”;the same as意为“与……相同”,其否定式与be different from同义。
运用主动语态与被动语态的变化来转换同义词,但此时要特别注意时态、动词一致性。如:
1. Everyone should give back his library books on time.
Library books should____ ____ ____ on time.
答案:be given back
解析:被动句中含有情态动词should,因此助动词用be。
