➢ 如何判断是否是独立主格结构？
1）构成：名词the level +现在分词going up;

构成 名词 / 代词 + 分词（现在分词；过去分词；不定式；形 容词；副词；名词；介词短语）
1）动词不定式表示动作没有发生或即将发生； The manager looks worried，many things to settle. 经理看上去很着急, 有这么多的事情要处理。

2. Yesterday I went fishing, something I hadn’t done in years.
3. Some women are normally inactive but then all of a sudden start a program of intense exercise, an action that breaks the laws of sports science.
（不定式to settle表示事情还没有处理） 2) 过去分词形式表示动作已经结束；
