1. 先行词the reason的后面是定语从句，B，D不能引导定语从句，且引导词作explained的宾语，而why只能作定语从句中的原因状语。答案C（that作explained的宾语，被省略）
2． Lily 虽然拼命的想要把门打开，但还是不能把门打开。As(虽然，尽管)引导让步状语从句时，从句中有副词修饰动词，把副词放句首，其它不动；有形容词/名词在从句中作表语时，形容词/名词放句首（不要把be等系动词也放句首），（过去分词相当于形容词作表语时，也要放句首）名词放句首要省略冠词；从句中有助动词/情态动词，要把情态动词/助动词后的动词原形放在句首 答案B open可以作形容词表开着的状态，也可作动词打开。 How soon will the door be open(形容词作表语，表开着的) how soon will the concert be open/opened(开始的) close作形容词（接近，靠近） closely(亲密地) close作动词（关闭） closed作形容词表关着的状态
3． Quite 是副词，student是名词作表语，都要放句首（不要看到有情态动词may就把be—-系动词原形给放句首，在这里be是student作表语的标志，如果把be动词放句首，那么不就和只把表语放句首（只能把作表语的那个名词放句首，不能把be动词也带到句首去）发生矛盾了吗）。答案D
4. 学生们当然知道很多单词，表达式，但他们写不出一篇好文章来，像这样的例子（情况）我能想出好多。Case（情况，例子）作先行词时，由where来引导定语从句。 答案D
5． 刘翔为了赛跑伤愈复出是很可能的。Chance后面的从句就是说明chance（可能性）的具体内容，这时关系词引导的从句就是同位语从句。排除D 引导名词性从句的关系词都能引导同位语从句，但只有that只起连接的作用，不作任何成分，没有任何含义。If不做成分，表“是否”，which作主语，宾语，表语，定语，表“哪一个”答案A sth is that=there is sth that(多数情况下都是由that引导同位语从句)
