Non-defining relative clauses非限定性定语从句
Relative clauses add extra information to a sentence by defining a noun. They are usually divided into two types –defining relative clauses and non-defining relative clauses. 定语从句是对句子里的名词加入额外的信息。一般来讲,有两种类型的定语从句—限定性定语从句和非限定性定语从句。 Non-defining relative clauses 非限定性定语从句 Look at this sentence. 看看这个例句 • My grandfather, who is 87, goes swimming every day.‘who is 87’ is a non-defining relative clause. It adds extra information to the sentence. If we take the clause out of the sentence, the sentence still has the same meaning. ‘who is 87’是非限定性定语从句,它给句子增加了额外的信息,如果我们把从句从句子里拿出来,句子的意义没有受影响。 Look at some more examples. 看看更多的例句 • The film, which stars Tom Carter, is released on Friday.• My eldest son, whose work takes him all over the world, is in Hong Kong at the moment. • The car, which can reach speeds of over 300km/ph, costs over $500,000. Non-defining relative clauses add extra information to sentences. 非限定性定语从句给句子增加了额外的信息。 Defining or non-defining? 限定性还是非限定性? Remember that defining relative clauses are used to add important information. The sentence would have a different meaning without the defining relative clause. 请记住,限定性定语从句是给句子增加了重要的信息,句子如果没有了定语从句,其意义不同。 • I’m going to wear the skirt that I bought in London.The defining relative clause tells us which skirt. 限定性定语从句告诉我们是哪个短裙。 • The skirt, which is a lovely dark blue colour, only cost £10.The non-defining relative clause doesn’t tell us which skirt – it gives us more information about the skirt. 非限定性定语从句不会告诉我们是哪个短裙,它给我关于短裙的更多信息。 Non-defining relative clauses can use most relative pronouns (which, whose etc,) but they CAN’T use ‘that’ and the relative pronoun can never be omitted. 而非限定性定语从句能用关系代词which和whose等等,但是它们不能用that,其句子中的关系代词也不可以被省略。 • The film, that stars Tom Carter, is released on Friday.Non-defining relative clauses are more often used in written English than in spoken English. You can tell that a clause is non-defining because it is separated by commas at each end of the clause. 相比起口语,非限定性定语从句更多地用于书写英语,你能辨认出哪个是非限定从句,因为习惯会在每个从句的结尾,用逗号分开。 |
