Yeah, There is no doubt that the earth is becoming warmer and that it is human activity that has caused this global warming rather than a random but natural phenomemon. You guys got the correct answer. And boys and girls, please pay attention to the noun “doubt”, can you tell me whats the relationship between the noun “doubt” and that clause? Great, that clause aims to explain the content of doubt. So it is apposition. And in English, we call this kind of clause appositive clause. Got it? Since you have known the basic definition of appositive clause, this time Ill give you more examples. Please look at the PPT, here are some sentences for you and you should find out the conjunctions of these appositive clause. Two minutes for you. Here we go. Any volunteers? Linda, you have a try. Wonderful. “that, whether, who, when, what.” Great. Boys and girls, look at these two sentences on the blackboard. The first one is “The news that our team has won the match made me happy.” The second one is “ The news that she told me was true.” Can you tell me the differences between the two sentences. Now you can work with your partner and talk about it. OK, guys, have you got the differences? Hmm, Jack, you have a try. Wow, you said the first sentence is appositive clause. Because that clause is to explain the content of the “news”, while the second one is attributive clause. And that clause is to modify antecedent news. Jack you give us a perfect explanation. Do you guys agree with him? I cant agree more.So class, now lets have a conclusion about appositive clause.
