老师好，在网上看到一个句子，
When Reader’s Digest asked Pien if there was anything she wanted to share as this crisis spread out, here’s what she had to say...
句中的this crisis指的是新冠。
1. 定语从句可依据需要选择时态，状语从句呢？新冠现在仍在蔓延，句中的spread可否用一般目前时？
2. 主从句感觉逻辑上、时态上，稍微有点儿别扭，想请教老师，这么用时妥当的吗？改成here was what she...不对的吧？
1 as引导的是时间状语从句。as从句与与主句谓语需要是同一个时间。所以不能把spread改为目前时。as从句谓语和新冠目前是不是还存在没任何关系。一百年后没新冠了，这个句子仍然可以说，时态还是正确的。
2 这个句子的when从句并非主句的时间状语，而是Here is what she had to say...这个倒装句中的主语从句的时间状语。用一个“时髦”的术语，这个when从句修饰what从句，整体是个嵌入分句，是主句here is sth这个倒装句中一个句子成分——主语从句。所以这个句子是没错误的。只是为了强调，而把主语从句的时间状语提前到了句首。改一下顺序，你就了解了：
Here is what she had to say...when Reader's Digest asked Pien if there was anything she wanted to share as this crisis spread out.
