我的长难句练习

从上个星期开始跟着海豚姐练习真题长难句，感觉很有意思。于是，我找了份长难句的资料（徐绽的）自己练习翻译。这个帖子我是想把翻译中感觉困难的句子贴出来大家讨论~~~

下面是今天的句子：
1999 passage 4
but they were divided on whether to go further by calling for a federal law that would impose a complete ban on human cloning.

浅析
句子主干they were divided on whether to go further,对是否更进一步(做...)，他们意见不一。
by calling for a federal law 通过呼吁立法（使之进一步<go further>）
that would impose a complete ban on human cloning.定语从句，修饰law.
