▲Investors and brokers have also found themselves under investigation by the authorities. And despite official declarations that the crisis is over, many believe there is further to fall, especially with the economy continuing to slow.
▲红色部分的 many believe there is further to fall 中，many believe 是主句，there is further to fall 是宾语从句。这个宾语从句是一个 there be 句式，其中的 further 是主语（它在此为形容词，可视为其后省略了名词 space 等），to fall 是定语。句子意思是：很多人还是相信（指股市）会进一步下挫。
▲全句大意：投资者和经纪商也发现他们自己受到了当局的调查。尽管官方宣告危机已经过去，但很多人还是相信（指股市）会进一步下挫，尤其是因为经济形势还在继续放缓。
