V-ing用法与图表观点类写作
自主探究语法:V-ing作定语,状语和宾补
V-ing短语在名词/代词后作定语
V-ing作宾语补足语
V-ing作状语
单个V-ing在名词/代词前作定语
V-ing完成式为having done, 强调动作先发生
1. JustDance is a website belonging to all dance lovers.
2. The lady running the website had the idea after she watcher her daughter dancing.
3. The website welcomes inspiring stories from dance lovers.
V-ing作定语 (attributives)
回归课文
1. Anybody going online should be careful about their personal information.
2. With access to the Internet come some truly life-changing advantages.
1.充当定语的现在分词短语一般位于修饰的名词或代词之后,若是单个单词则位于被修辞词之前。
2.现在分词与过去分词都可以充当定语。区别在于:V-ing表进行,与被修饰词构成主动关系;V-ed表完成,与被修饰词构成被动关系。
比较: fallen leaves 与 leaves falling from the branches

范文赏析
Personally, I am against bringing mobile phones to campus. While they are useful tools, they often do more harm than good in a school setting.
Admittedly, phones allow students to contact parents in emergencies and access learning apps. However, like Pandora's box, they bring distractions. Many students can easily feel distracted by games or social media during class, which is harmful to their academic performance.
Therefore, I believe schools should limit phone use on campus. A focused learning environment benefits everyone.
