基本上 let alone 不用再句首,只用在句中。连接两个句子,有进 一步比较之意,译为:更不用说 给你几个例句。

let alone 后面跟 do 和 doing 的区别 let alone 后面结构主要取决于其前面对比内容结构,即要与其前面 结构保持一致!

例如1.Protecting the air,let alone improving it,is a challenge. 别说要改善空气了,现在就是保护它也很难. 2. The central government has struggled to count this debt,let alone control it. 对此中央政府连贷款金额都无法汇总,更别说对贷款进行调控. 3.
