you can't swim in the sea.there are a lot of sharks in the sea.
我看答案是写成
you can't swim in the sea where there are a lot of sharks in the sea.
这里sea不是做主语吗?>怎么还可以用where啊
可不可一改成这样?
you can't swim in the sea that或者是which there are a lot of sharks in the sea.
为什么不可以用that?

Answer 1

Where在这里作状语 这不是个定语从句 是地点状语从句 所以说改成定语从句不对。Where there 是个很重要的句型，你就把它背过，当初我也不是很明白，缠了老师一下午最终还是记下了。多背背吧，以后用得着。这个句子后面稍显重复。改成you can't swim in the sea where there are a lot of sharks.地点状语从句。去点多余累赘in the sea~

Answer 2

那是in the sea ，是地点壮语，要用where 来引导。
改的话，可以改成you can't swim in the sea in which there are a lot of sharks .

Answer 3

英语不好
好像可以用where和that 不能用which吧
但是不管怎么说 答案中没有那么多in the sea吧

Answer 4

sea是先行词，要用where来引导，因为后面的从句there are a lot of sharks in the sea.是一个完整的句子所以不需要which,that。因为定语从句中which,that要不作主语要不作宾语。而where在这里是一个地点状语用来修饰先行词sea。
