高考臨近，以下是有兩道易錯(cuò)的非謂語(yǔ)動(dòng)詞作狀語(yǔ)考題，希望對(duì)大家有所幫助！
請(qǐng)看下面的兩道題：
1. _________from the operation, the patient had to stay in hospital for another two weeks.
A. Having not fully recovered
B. Having not been fully recovered
C. Not having fully recovered
D. Not having been fully recovered
【答案與解析】此題容易錯(cuò)選D，其實(shí)正確答案是C，此題考查分詞作狀語(yǔ)的用法。由于非謂語(yǔ)動(dòng)詞的否定形式總是將否定詞置于非謂語(yǔ)動(dòng)詞之前，而不是之后或之中，故可可排除A和B;而recover是不及物動(dòng)詞，不能用過(guò)去分詞表被動(dòng)，故可排除D。即答案選C。
2. _________ in China once a year, the National Day is one of the most popular festivals in China.
A. Celebrating B. Celebrated C. Having celebrated D. Having been celebrated
【答案與解析】此題容易錯(cuò)選D，其實(shí)正確答案是B，此題考查分詞作狀語(yǔ)的用法。由于celebrate 和the National Day是動(dòng)賓關(guān)系，故可排除A和C;又因?yàn)閛nce a year這個(gè)時(shí)間狀語(yǔ)，強(qiáng)調(diào)的是動(dòng)作一般狀態(tài)而不是完成，所以選B。
