“such that”是英语中连接形容词/代词与从句的常用短语,核心含义是“如此…以至于”“使得”,用于说明前文事物的特征、结果或条件。它的用法可分为三大类,以下结合语法结构和例句详细说明:
“such that”本质是通过从句补充前文的信息:
若前文是名词/代词(被“such”修饰),则从句说明该事物的具体特征或结果;
在数学/逻辑中,直接表示“使得”(引出条件)。
结构:such + [形容词 +] 名词 + that从句
“such”修饰名词,“that”引导从句说明前文内容导致的结果(that在从句中不充当成分)。
修饰单数可数名词:`such a/an + 形容词 + 名词 + that`
e.g. He told such a funny joke that everyone laughed for minutes.(他讲了个如此好笑的笑话,以至于大家笑了好几分钟。)
修饰复数可数名词/不可数名词:`such + 形容词 + 名词 + that`
e.g. They have such kind parents that all their friends envy them.(他们的父母如此善良,以至于所有朋友都羡慕他们。)
e.g. The storm caused such heavy damage that the town took months to recover.(暴风雨造成了如此严重的破坏,以至于小镇花了数月才恢复。)
倒装结构:若“such”置于句首强调结果,句子需部分倒装(助动词/系动词提前):e.g. Such was her excitement that she couldn’t stop smiling.(她如此兴奋,以至于笑个不停。)
结构:名词 + such that从句
“such that”连在一起,引导定语从句解释前文名词的具体特征(相当于“of a kind that”)。此时“such”指代前文名词的属性,“that”在从句中可充当成分(主语/宾语等)。
e.g. We need a solution such that both sides can accept it.(我们需要一个双方都能接受的解决方案。)
(“such that”修饰solution,说明“解决方案”的特征——“双方能接受”)
e.g. There are situations such that you have to make a quick decision.(有些情况需要你快速做决定。)
在学术语境中,“such that”直接表示“使得”,引出变量或集合需满足的条件(类似“for which”)。
e.g. Find a number \( x \) such that \( x^2 = 9 \).(找一个数\( x \),使得\( x \)的平方等于9。)
e.g. Let \( S \) be a set such that all elements are integers.(设集合\( S \),使得其所有元素都是整数。)
两者都与“such”搭配,但功能不同:
such…that…:结果状语从句(强调“结果”,that不做成分);
such…as…:定语从句(强调“举例/特征”,as在从句中做成分)。
e.g.
1、 She bought such books that she spent all her money.(她买了如此多的书,以至于花光了钱。)→ 结果
2、 She bought such books as I recommended.(她买了我推荐的那种书。)→ 举例(as作recommended的宾语)
用法类型 | 结构示例 | 含义 |
---|---|---|
结果状语从句 | such + 名词 + that从句 | 如此…以至于(结果) |
定语从句 | 名词 + such that从句 | …的(特征) |
数学/逻辑 | 变量/集合 + such that条件 | 使得(满足某条件) |
“such that”是正式文体(学术、写作)中常用的连接手段,日常口语中更倾向用“so…that…”(so修饰形容词/副词),但掌握“such that”能让表达更精准、严谨。
