正確：The old worker insisted that he wasn't old and went back to the working post again.
主語(yǔ)是the old worker,并列謂語(yǔ)insisted和went (back),insisted帶一個(gè)從句：從句主系表結(jié)構(gòu),he wasn't old
went back寫(xiě)成back勉強(qiáng)可以,很不講究,back作動(dòng)詞表后退主要指倒退的動(dòng)作而不是狀態(tài),例如馬向后退了兩步：the horse backed steps.
正確：The old worker insisted that he wasn't old and should be sent back to the working post.
主語(yǔ)是the old worker,謂語(yǔ)是insisted,帶一個(gè)并列結(jié)構(gòu)的從句：從句主語(yǔ)he,第一部分系表結(jié)構(gòu),wasn't old,第二部分情態(tài)動(dòng)詞構(gòu)成的被動(dòng)語(yǔ)態(tài),should be sent back to the working post again
這句等于：
The old worker insisted that he wasn't old and (insisted that he) should be sent back to the working post.
不要聽(tīng)別人瞎說(shuō),這里的should是不可以省略的.
錯(cuò)誤：The old worker insisted that he wasn't old ,and be sent back to the working post again.
主句主語(yǔ)the old worker,從句主語(yǔ)he,不能直接接be sent back.
被動(dòng)語(yǔ)態(tài)的主語(yǔ)如果是人,一般表達(dá)一種狀態(tài),某某被怎樣怎樣了,某某將被怎樣怎樣,或某某正在被怎樣怎樣.insist堅(jiān)持,后用被動(dòng)語(yǔ)態(tài)的事情：一,不能是過(guò)去的事情；二,不可能正在進(jìn)行；三,施事者是別人也無(wú)法保證將來(lái)一定能夠?qū)崿F(xiàn),因此只能是應(yīng)該被怎樣表將來(lái)可能的一種狀態(tài).
