[正]Manynewbuildingshave beenbuiltsince2000．

[析]

謂語(yǔ)部分結(jié)構(gòu)不全,時(shí)態(tài)部分不完整。

試分析：[正]Manynewbuildingshav512)[誤]Somethingbadhasbeen happenedtohim．

[析]

被動(dòng)語(yǔ)態(tài)誤用。happen為不及物動(dòng)詞，不及物動(dòng)詞沒(méi)有被動(dòng)語(yǔ)態(tài)。

[正]Somethingbadhashappenedtohim.

2)[誤]Somethingbadhasbeen52[正]Thedoorhasopenedofitself．

[析]

有些動(dòng)詞如open,break,drop

等既可作及物動(dòng)詞，又可作不及物動(dòng)詞，若不強(qiáng)調(diào)誰(shuí)是動(dòng)作發(fā)出者，我們通常用主動(dòng)語(yǔ)態(tài)。of

itself意思是“自動(dòng)地”。因此,此句不可用被動(dòng)語(yǔ)態(tài)。3)[誤]Thedoorhasbeenopenedofitself．

[正]Thedoorhasopenedofits534)[誤]IhaveintroducedtoMrLi．

[析]introduce為及物動(dòng)詞,I是 introduce的承受者。
