In this way, you will find the answer to this question. 用这种方法，你可以找到这个问题的答案。way主要有以下几种用法：表示“方法”，接不定式，.way to do sth这一结构等于.way of doing sth。Scientists are trying to find ways to prevent(of preventing) disease. 科学家们正在寻找预防疾病的方法。There are many ways of traveling(to travel), for example, by air. 旅行有许多方式，例如乘飞机。表示“路途”，“路线”，常构成on ones/the way to.“在的途中”。在这一结构中，介词to表示方向，后接名词。如果后面接地点副词如here, there, home时则不用to。Im on my way home.我正在回家的路上。Shes on her way to see the film.她正在去看电影的路上。表示“方向”。Look this way.看这边。 Go that way.往那边走。表示“距离”，“路程”。 Beijing is a long way from here.北京离这里很远。4. In England, tea didnt appear until around 1660.在英国，茶直到1660年才出现。此句是由until引导的时间状语从句。not. until 意为“只到才”。She didnt leave until I felt better.只到我感觉好点了，她才离开。【横向辐射】until的用法until常用作介词或连词，用来引导介词短语或从句在句子中作时间状语。在肯定句中，until与延续性、持续性动词连用，表示“直到为止”。I worked until late in the afternoon. 我一直干到下午很晚的时候。五、练评（包含“考点链接” 应用探究 6分钟）（ ）1.
