名詞性從句的功能分別為:做主語、做賓語、做介詞賓語
還是圍繞著:that、whether、6W1H(疑問句),他們做以上三種句子,都均有部分變化
名詞性從句做主語:
同時形式主語it的轉變
Whether he can do it remains to be seen. 當主語過重,可用形式主語--> it remains to be seen whether he can do it(真正的主語就變後面),需要我們區分它
Where he lives is still doubt ---> it is still doubt where he lives
That he must to practice basketball can be able to competition in next week
---> it can be able to competition in next week that he must to practice basketball
名詞性從句做賓語(需要分清形式主語it和賓語之間的區別,因為都將名詞性從句放在後頭)
句型表述為 主語+不完全及物動詞(vt)+賓語,這是英語中五大句型之一
I wonder whether he can finish the work
I don’t know how better to learn english
S+vt+o
名詞性從句做介詞賓語
分兩種情況
(1)介詞後面可以直接+whether或疑問詞(6W1H),但不能直接+that從句
例子: i am worried about (that X) + whether he could hold on the door handle
I an worried about how he can bear the pain
(2) 如需+that從句,則需要添加額外的詞語也分三種情況
第➀種情況:介詞+the fact +that從句
The fact作為賓語,而that從句是the fact 的同位語(可以簡單理解補充the fact的意思)
例子:i am worried about the fact (賓語o) + that he without care danger(同位語)
I am sure of(介詞)the fact that the team has won the game (has 第三人稱過去式)
第➁種情況:如果不用the fact ,在介詞後面 +that ,那麼句型將會需要分三步
●去掉that
●將名詞變成所有格(名詞+’s,he->his, i-->my, you-->your )
●動詞變動名詞
註:
1.因that去掉沒有形成常規主語,因此後面的需要變化成常規主語,這種方法較為固定,需要以記憶為主,他將that從句隱藏,轉換了動名詞的從句。
2.有助動詞do、does、did、will、would都需要去掉。
例子:
I am worried about that he plays around all day-->i am worried about his playing around all day
I am worried about that he didn’t sleep --> i am worried about his not sleeping
I have a dream about that the team will win the competition--> i have a dream about the team’s winning the competition
但有2個助動詞比較特別,can 、may則需要變化相關句型
Can---> be+ing likely to
May--->be+ing able to
I am worried about that he can drive the car on the road,because he just take the licence--->
I am worried about his being likely drive the car on the road ,because he just take the licence
第➂種情況:去掉介詞形成句型 be+adj+that從句,that從句就是adj的賓語,這樣改動最少,而且快捷,需要注意前面是否是形容詞,不過介詞前面大部分都是形容詞,後面用從句,只是作為補充說明前面的情況,寫作時避免錯誤,可靈活多用些簡單的,避免出錯
例子:
I am worried about that he can’t finish the task--->i am worried that he can’t finish the task
That遇介詞概括就是:
●第➀保留介詞和that,但需要加the fact ;第➁保留介詞,去掉that,改變從句特性;第➂保留that,去掉介詞
●第➀➂是最常用的,第➁則當句子看到介詞是,需要想到that是否被去掉,同時將句子還原
補充that:
第➃種,特殊用法,習慣性句型
in that =because 因為
Notwithstanding that =even 儘管
以上介詞賓語,名詞性從句的特點(總結的就是that比較多事)
從上概括名詞性功能分主語、賓語、介詞賓語,他們各有特點,而當介詞賓語時,需要特別注意that的用法,因為還是那句就他多事,而且也常用that作為引導
