sothat和so...that在含义和用法上都存在明显的区别。sothat和so...that都可以表示“以便”或“为了”,但sothat更强调结果,而so...that更强调原因。
例如,使用sothat时,句子通常描述的是为了达到某个目的而采取的行动或方法,例如:I got up early sothat I could catch the bus.(我早起是为了赶公交车。)而使用so...that时,句子描述的是某件事导致的结果或影响,例如:She worked hard sovthat she passed the exam.(她努力学习以便通过考试。)
此外,sothat和so...that在用法上也有所不同。sothat通常引导目的状语从句,而so...that可以引导结果状语从句或目的状语从句。例如:The teacher spoke clearly sothat all the students could understand him.(老师讲得很清楚,以便所有学生都能听懂他的话。)(目的状语从句)She worked hard sovthat she passed the exam.(她努力学习以便通过考试。)(目的状语从句)He built a house so large that it could accommodate 50 people.(他建造了一座如此大的房子,以至于可以容纳50人。(结果状语从句))
总的来说,sothat和so...that的主要区别在于含义和用法上。sothat更强调结果,引导目的状语从句;而so...that更强调原因,可以引导结果状语从句或目的状语从句。
