【只用that不用who的八种情况】在英语学习中,关系代词“that”和“who”常常让人混淆。虽然两者都可以引导定语从句,但在某些情况下只能使用“that”,而不能使用“who”。为了帮助大家更好地理解和掌握这一知识点,本文将总结出只用 that 不用 who 的八种常见情况,并以表格形式进行清晰展示。
一、
1. 先行词是不定代词:如 everything, anything, nothing 等。
2. 先行词是指示代词:如 this, that, these, those。
3. 先行词既有人又有物:当先行词同时包含人和事物时,只能用 “that”。
4. 先行词被最高级修饰:如 the best, the most important 等。
5. 先行词被 only, any, all, no, some 等限定词修饰。
6. 从句中缺少主语或宾语时:如果从句中没有明确的主语或宾语,通常使用 “that”。
7. 非限制性定语从句中:虽然一般不用于非限制性从句,但有时也可用 “that”,不过此时更常见的是 “which”。
8. 在强调句型中:如 “It is... that...” 结构中,只能用 “that”。
这些情况在语法学习中非常重要,掌握它们有助于避免常见的语法错误,提升语言表达的准确性。
