精准度(3):句子成分错误版本：Young people live with their parents can save a lot of money.
正确版本：Living with parents can save young people a lot of money.
精准度(4):动词使用-错误版本：Students should wear uniforms go to school.

⒉提高多样性
多样性⑴:定语(修饰名词)-形容词/介词短语/定语从句/分词短语-每一篇文章里至少各自使用一次
练习：只有一个孩子的家庭-families which have only one child – families with only one child – families having only one child
多样性⑵：状语从句-表达逻辑关系+提升语法宽度：时间/条件/原因/结果/伴随/让步
