老师好， H7N9 is a virus caused by bird flu. And it has a huge threat to our heath, so it's necessary for us to take some effective measures to protect us against H7N9. 怎样把这句话改成which引导的非限制性定从?
解题思路： 定语从句
解题过程：
1. H7N9，which is a virus caused by bird flu， has a huge threat to our heath, so it's necessary for us to take some effective measures to protect us against H7N9.
2. It's necessary for us to take some effective measures to protect us against H7N9，a virus caused by bird flu， which has a huge threat to our heath.
H7N9，是两个句子中都提到的名词，可以把它当做先行词，因为这是个专有名词，适合用非限定性定语从句。
如有不同意见，欢迎附加讨论。
最终答案：略
