    3. 名词从句
     名词从名包括主语从句、宾语从句,其中有介词与形容词的宾语从句、表语从句和同位语从句。
    1 )主语从句
     主语从句常出现在 “it is + 名词、形容词、分词 + 主语从句 ” 的形式中。例如:
    It is reported that Taiwanese pop singer Meng Tingwei will hold a solo concert in Shanghai someday this month.
    It must be pointed out that you have failed to meet the deadline.
    It usually happened that I was late because of traffic jams.
     主语从句还可用 when, where, how, why, whether 等连接副词,和 who , whom , whose , what , which , whoever , whatever , whichever 等连接代词来引起。例如:
    How to arrange the meeting is not your task.
    Whose candidate will win the election is the question both political parties are asking.
    When I leave is my own decision.
    Whoever will go to the party won't change my mind of staying at home.
    2 )宾语从句
     宾语从句可由 that, 疑问代词或副词 how, why 和 where 等引出。例如:
    To postpone the conference until next month indicated that they were unprepared.
    Nearly all the staff agreed with what I said.

    Everyone worried about her because no one was aware of where she had gone.
    Could you offer more details except that it happened at night?
     由 what, whether, how 引导的宾语从句可用在介词后,而由 that 引导的从句只跟 but, besides, except, in, save 之后。例如:
    I can hardly believe in what they have done.
    He doesn't know my phone number except that the city code is 021.
     一些表语性的形容词,如: alarmed, amazed, annoyed, astonished, certain, confident, disappointed, glad, pleased, proud, sad, shocked, sure, surprised, worried, ect. 作表语时,后面可跟由 that, how 等引导的宾语从句。例如:
    I was amazed how he could pass the exam without attending the lectures.
    He is confident that he will pass the Band 6 examination.
    She was surprised how simple his problem was.
    We are all pleased that he will be able to pass the final examination.
    3 )表语从句
     表语从句对主语的内容起解释和阐述的作用;若表语从句用 that 引起, that 起连接作用,不能省略。表语从句也可用连接词 how, when, where, why, what 引起。由  because 引起的表语从句通常只用在 “this/that/it is because” 结构中。例如:
     On thing I admire most about them is that they are hospitable.
    She works too hard. That is why she is exhausted.
    I must point out that where you intend to build a super-market is where the elderly do exercise everyday.
    4 )同位语从句
     同位语从句是由两个或两上以上同一层次语言单位组成的结构,其中前项与后项所指相同,句法功能相同。同位词从句由 that 引导,也可由 whether, how, why,  where, when 等来引导。例如:
    She ignored the teacher's instruction that she must study hard.
    The question whether or not I should help him in such a case troubled me greatly.
