根据上句It is home to nearly 400 species of fish.长江是将近400种鱼类的产地和首字母的提示可知,空处的词应是形容词“普遍的、普通的common”,故答案为common

3

句意:这种鱼可能在2005年到2010年的某个时间灭绝。

根据语境,这种鱼在2005年到2010年的某个时间灭绝,只是科学家的一种估计;再结合首字母,空处的词应是副词“可能likely”,故答案为likely

根据它的昵称“大象鱼”和首字母提示可知,空处的词应是名词“鼻子nose”,因位于冠词a之后,单数形式即可,故答案为nose

7

句意:中华鲟是一种古老的物种。

根据下句It first appeared in the Jurassic period(侏罗纪时期).它第一次出现在侏罗纪时期和首字母的提示可知,空处的词应是形容词“古老的ancient”,做定语修饰名词species,故答案为ancient

8

句意:在存在了两亿年之后,这个物种因为人为活动最后灭绝。

根据常识可知,大部分物种的灭绝都与人为因素有关;再结合首字母提示,空处的词应是名词“活动activity”和human一起构成“人为活动、人为因素”,人为活动有很多,所有用复数,故答案为activities

9

根据下句The Chinese paddlefish was only the first to disappear.中华鲟仅仅是第一个消失的和首字母提示可知,空处的词应是名词“危险danger”,故答案为danger
