A containing

B in which containing

C contains

D that contain

选D的话, 数不对. 要用

that contains

多谢！！！！

Drinking water which is excessive amounts of fluorids may leave a stained or mottled effect on the enamel of teeth.

补全以后的结构应该是这样的吧

错误肯定不只一个

出现了3个谓语. 必须改掉两个.

这道题我后来有想了一下。是不是首先have been时态没有依据？而且好像应该是be known as

当时考虑的是located 和 seperated 并列所以选择了B. 所以即使改了A还是觉得不正确。

郎文上的用法to have a particular name。

  

be known as

have never been known to do something

望指正

2. Coral formations have known as fringing reefs are located close to shore, separate from land only by shallow shallow water.

have known>>>known,    这里separate做形容词，分开的，分离的
