[size=14.007px]The number of plant and animal species that [size=14.0084px]humans are known to have forced to extinction[size=14.007px] in the last half millennium is over 800.
[size=14.007px]a.
[size=14.007px]b. humans are known as having forced to become extinct.
[size=14.007px]c. humans are known for forcing to become extinct.
[size=14.007px]d. are known that humans forced to become extinct.
[size=14.007px]e. are known as having forced to extinction by humans.
[size=14.007px]
[size=14.007px]A选项,我觉得 整个划线部分修饰前面的species
[size=14.007px] be known to 不是应该表示被动吗,为啥是人 被所熟知。
[size=14.007px] 还有一种理解,我觉得是humans are known 来修饰species,但是这样不应该加be动词啊。
[size=14.007px]求助!!!!!
