Such good use has been made of his spare time (as) his English has improved a lot为什么是填as呢?that不行吗?

问题描述:

Such good use has been made of his spare time (as) his English has improved a lot
为什么是填as呢?that不行吗?

我觉得就应该用that分析:原名变为主动:He has made such good use of his spare time that his English has improved a lot.他利用业余时间是如此充分结果他的英语进步很大.这里的such...that...(that引导的是结果...
