1 What do "where", "which" and "when" refer to in each sentence?
2 Which sentences contain a clause with essential information and which with extra information? If you take away the clauses, do the sentences still make sense?
3 Which clauses are separated by a comma, the ones with essential information or the ones with extra information?
活动1参考答案：1 In sentence (a)"where" refers to "the waiting area"; in sentence (b) "which" refers to "...laughter produces chemicals to make people feel better"; in sentence (c) "when" refers to "the time".
2 Sentence (c) contains a clause with essential information, sentences (a) and (b) contain clauses with extra information. If we take away the clause of sentence (c), the meaning of it is incomplete. If we take away the clauses of sentences (a) and (b), the two sentences still make sense.
3 Sentences (a) and (b) with extra information are separated by commas.
