27、bial after the verb-ing. Verb-ing phrases can express the time, the reason, the result, and the condition. Sometimes we can change verb-ing phrases into adverbial clauses. (现在分词短语通常可以单独使用，也可以在其后面跟宾语和状语，用来表示时间、原因、结果、条件、方式或伴随情况等。通常可以转换成相对应的状语从句。)1Express the time (表示时间) We can use clauses introduced b
