雅思写作语法学习：必要定语从句和不必要定语从句 Essential and Nonessential Adjective Clauses 必要定于从句和不必要定语从句 Remember that an adjective clause is a dependent clause that acts like an adjective in the sentence. This means that it gives more information about a noun or pronoun in the sentence. 定语从句是一个从属分句，在句中作形容词。可以给出更多关于句中名词或代词的信息。 Sometimes the information given by the adjective clause is essential. An essential adjective clause is one that is needed for the sentence to make sense. If you took it out, you would not know all the information that you need to know. 有时，定于从句提供的信息至关重要。句中需要这一从句使句子的意思更完整。如果缺少此从句，就了解不到完整的信息。 At other times, the information given by the adjective clause is nonessential. A nonessential adjective clause is one that is not necessary. The sentence still makes sense and you know everything you need to know even without the clause. So, you could take it out. 有些时候，定语从句提供的信息不是那么重要。没有这一从句，句子也有意义，而且意思完整。因此可以删掉这一从句。 When a sentence has a nonessential adjective clause, the clause is set apart with commas. This shows that it is not essential. 如果一句中有不必要定语从句，就会用逗号把从句隔开，表示这句话并不是必须的。 |
