1.However,as the evidence began to accumulate,experts from the Zoo felt obliged to investigate, for the descriptions given by people sho claimed to have seen the puma were extraordinary similar.这一句as引导什么从句?as有哪些用法,关于as引导从句有哪些知识点?for是连词吗?for引导从句吗?
2.As no pumas have been reported missing from any zoo in the country,……这里的missing等于have done 吗?另外,zoo竟然是不可数名词吗?
3.课下注释5:puma fur was found clinging to bushes中,clinging是主语puma fur的主补。 为什么不是宾补?be found doing,可以理解成宾补吗?
