GWD-23-Q31 STILL CONFUSED...

According to some botanists, invasive plants are the second most serious threat, after habitat loss, to native species of plants and animals and to the maintenance of biologically diverse ecosystems.

threat, after habitat loss, to native species of plants and animals and to the maintenance of biologically diverse ecosystems

threat, after habitat loss, to native species of plants and animals and for maintaining biologically diverse ecosystems

threat, after losing their habitat, to native species of plants and animals and also to maintenance of biologically diverse ecosystems

threat to native species of plants and animals and for maintaining biologically diverse ecosystems, after habitat loss

threat to native species of plants and animals as well as to maintaining biologically diverse ecosystems, after losing their habitat


依旧不明白C有什么特别不好的地方？
我觉得就是没有A简洁而已，可是 after losing their habitat,我觉得指代也没什么不清楚，逻主也对啊。。。

句中讲了两个threat 前面的invasive plants 后面应该对应的就是habitat loss了

谢谢fengshou，一语惊醒梦中人～～～
突然看懂了，谢谢～～～

但是A中为什么要用the？

fannybeibei

是指to the maintenance of 么？
我当时也想过，但是我觉得这里加不加the都是可以的，可以认为是泛指，也可以认为是特指maintenance of biologically diverse ecosystems

觉得自己没有理由支持来说清楚，花子落落sorry了。。。

fengshou

没有the给我的感觉就是maintenance裸奔了。。。

我觉得做这道题的思路可以是这样的：
首先为了保持平行应该用threat to and to,所以将B、D排除
然后E选项to maintaining明显语法错误，所以排除
最后剩下A、C。但是C中的their明显指代不清。题目要表到的意思是：威胁有两个，首先是habitat loss,然后是invasive plants 。那么这里的habitat loss到底值得是谁的habitat呢，我觉得值得是后面的plants and animals ，反正绝对不是前面的invasive plants 。如果你用their的话，their紧跟在invasive plants 后面，很容易让人觉得指代的是invasive plants ，会出现指代错误的问题。再说，habitat loss与 invasive plants 都是名词，从保持一致上看比losing their habitat好。

thanks, Gabriel
你说得真好

我理解and also 不能表示并列，必须去掉also
