　　结构划分：

　　①But it has already sparked significant controversy

　　②with the United States trade representative opening an investigation into

　　③whether the tax discriminates against American companies,

　　④which in turn could lead to trade sanctions against France.

　　重点单词：

　　spark v. 引发，触发

　　controversy n. 争论，争议

　　representative n. 代表；adj. 有代表性的

　　investigation n. 调查

　　discriminate against 歧视

　　sanction n. 制裁

　　语法分析：

　　本句的主干部分是“But it has already sparked significant controversy”，意思是“但是，它已经引发重大争议”。With结构则作状语：其中whether从句跟在介词的后面为宾语从句，该从句中，the tax为主语，discriminates against 为动词短语作谓语，American companies为宾语。which in turn could lead to trade sanctions against France为定语从句，其中which作主语，could lead to 谓语，trade sanctions为宾语。

　　参考译文： 但是，它已经引发重大争议，美国贸易代表开始调查这项税收是否歧视美国公司，这又可能导致对法国的贸易制裁。
