英语句子里,双逗号中间的是插入语还是同位语 In group to remain in existemce,a profit-making organization must,in the long run,produce something consumers useful or desirable. 分析一下这句话的成分
插入语可以插在句子的前面后面和中间.譬如: I think that Mr.Zhou will be back this afternoon. =Mr.Zhou,I think,will be back this afternoon. =Mr.Zhou will be back this afternoon,I think. 同位语必须在特定的词之后.譬如: My grandmother,the owner of this house,is kindhearted. 还有一种情况,就是伴随状语.譬如: I,smiling,embraced her. She,went out,tears in her eyes.
