Were ID. Was I 答案C. 在虚拟条件状语中如果有were, should, had这三个词，通常将if省略，主语提前, 变成 were, should, had +主语的形式。但要注意，在虚拟条件状语从句中，省略连词的倒装形式的句首不能用动词的缩略形式。如我们可说 Were I not to do, 而不能说 Werent I to do。 5）_ your address，I would have written to you.A. Did I know B. Were I to knowC. Had I known D. If I should know此题应选 C。这是虚拟语气的倒装形式。专心-专注-专业
