【suchthat和sothat区别】在英语语法中,“such that”和“so that”都是用来引导目的状语从句的结构,但它们在用法、语序和语气上有着明显的区别。正确理解这两个短语的差异,有助于更准确地表达句子的意思。
一、
1. such that
“such that”通常用于描述一个结果或状态,后面接的是一个完整的句子,强调的是“如此……以至于……”。它常用于正式或书面语中,结构为:
such + 名词 + that + 主语 + 动词。
例如:He is such a good student that he always gets high marks.
2. so that
“so that”则表示目的,意思是“以便……”,强调的是动作的目的性。其结构为:
so + 形容词/副词 + that + 主语 + 动词。
例如:She studied hard so that she could pass the exam.
需要注意的是,“so that”引导的从句中,主语和动词可以是原句的主语,也可以是另一个主语,而“such that”中的主语一般与主句一致。
