at this time yesterday與this time yesterday沒(méi)有本質(zhì)的區(qū)別,意義是一樣的.同源賓語(yǔ)在結(jié)構(gòu)上與某些及物動(dòng)詞有關(guān)聯(lián),以名詞形式重復(fù)動(dòng)詞的全部或部分意義,是一種特殊的直接賓語(yǔ).例如：I dream a good dream.He will sing a song for us .
同源賓語(yǔ)只是一種習(xí)慣用法,并非任何動(dòng)詞都可以接同源賓語(yǔ).另外,有的同源賓語(yǔ)只是重復(fù)動(dòng)詞的意義,從詞源角度來(lái)看兩個(gè)詞并不同源.如：She only slept a wink last night.this time yesterday?????????????????? ????last ,next , this ??that ????????? ??????? ???? yesterday??theday before yesterday ?????????????????? ???????? ?? was / were + doing??this time yesterday ??at this time yesterday??????????????????????????????????????????????????????????????????????????????????ο???????????????????????at?????????????????????????????????????????,????????????????????
