Here's some advice: First,remember_(identify)noun clauses by their function in a sentence.A noun clause can act as a subject,object,or predicative.For example,"you said just now is very important"is a subject clause, where”_”acts as the subject of the clause. Second,pay attention to non-finite verbs in noun clauses.When a noun clause follows"whether"or"how", it often uses the structure"whether/how+(do)".For example,"I don't know whether(join)the club" uses the infinitive after "whether'. Third,avoid common mistakes.For instance,the reason for your failure is_you didn't study hard,not ”why”.Also,in indirect speech,always use陈述句语序："She asked me where I_(Iive)', Finally,practice combining noun clauses and non-finite verbs.For example,"The key is how _(improve) your skills"uses a predicative clause with"how infinitive".Remember,(master)these rules takes time, but it's worth(try). 答案区 演练-：1B2.C3.A4B5B6.C7.D8.C9B10B 演练二：1.if/whether2.What3.that4.to study5.how6.What7.whether/how 8had seen 9.Learning 10.not to be 演练三：1.to identify2.What3.what4.todo5.to join6.that7.lived8.to improve 9.Learning 10.trying 7
