修改建议：这个句子的结构应该是无可厚非的(语法就不说啦)，但是，按照雅思评分的标准，句式稍微做一下调整，会更漂亮： 如：It; is; clear; that; rush; hours; emerge; in; the; early; morning; as; well; as; in; the; early; evening; which; is; most; busy/the; busiest; in; a; day; as; a; whole; in; London. 或者改成 It; is; demonstrated; that; rush; hours; emerge; in; the; early; morning; as; well; as; in; the; early; evening; which; is; most; busy/the; busiest; in; a; day; as; a; whole; in; London. 这样一个小小的调整，其句子修改前后的效果是显而易见的。
