高中英語連線副詞知識點
連線副詞:
可分為兩類,一類是用於連線句子或從句,常見的有therefore, otherwise, however, moreover, still, thus, meanwhile等;
另一類是用於引導從句或不定式,主要有when, why, where, how等。
例如:We all tried our best; however, we lost the game.
Tell me when we shall leave.
I do not know how to find him.
連線副詞的特點:
一、連線句子或從句的連線副詞
連線副詞的性質類似於並列連詞,使用時其前通常用分號或句號;
若其前用逗號,則通常帶有並列連詞***如and***。如:
I don't like it; besides, it's too expensive. 我不喜歡它,而且也太貴了。
We all tried our best; however, we lost the game. / We all tried our best. However, we lost the game. 我們都已盡了最大的努力,不過我們還是輸了。
注意,有的連線副詞***如however等***後通常有逗號與句子的其他成分隔開。另外,有的這類副詞還可位於句中或句末:
Peter is our youngest child, and we have three others besides. 彼昨是我們最小的孩子,我們另外還有三個孩子。
He may, however, come later. 不過,他也許一會兒就到。
We all tried out best. We lost the game, however. 我們都已盡了最大的努力,不過我們還是輸了。
二、引導從句和不定式的連線副詞
用於引導從句***名詞性從句***或不定式的連線副詞主要有when, why, where, how等。如:
Tell me when we shall leave. / Tell me when to leave. 告訴我什麼時候離開。
I don't know how I can find him. / I don't know how to find him. 我不知道如何找到他。
Where we can get the money is just our problem. / Where to get the money is just our problem. 到哪裡去弄到這筆錢正是我們頭痛的事。
That's why he speaks English so well. 那就是他為什麼英語講得這麼好的原因。
注:連線副詞why 後不能不定式,如可說 I don't know why I must leave.***我不知道我為什麼必須離開***,但不能說 I don't know why to leave。
連線副詞的句法特徵:
所謂連線代詞和副詞,實際上就是我們以前學過的疑問代詞和副詞,如who, whose, whom, what, which, when,where, why,how以及由how構成的片語。
1.連線副詞起對等連線詞的作用,連線兩個句子或子句,如:
however, so, then,moreover,concequencely,hence,also,besides,,otherwise,therefore,thus等。
I feel a bit tired. However, I can hold on.我有點累了,但我能堅持下去。
They talked about it for hours. Finally, they decided to go。他們對此商量了好幾個小時,最後他們決定去。
2.連線副詞通常位於子句的句首,有的也可位於句中。
They talked about it for hours. Finally, they decided to go。他們對此商量了好幾個小時,最後他們決定去。
finally作為連線副詞,放在句子的句首。
I have never been to Wales. I, therefore, don't know much about it.我從未去過威爾斯,因此我對它知道的不多。
therefore作為連線副詞,位於句子的句中。
3.有些連線副詞的含義彼此相同或相近,在使用時可以互相替換,而不會改變原句的含義。
The weather was cold. Therefore***Thus***, we stayed home.天氣寒冷,因此我們待在家裡。
therefore和thus的含義相近,因而也可以互相替換。
在應用時要注意以下兩點:
一是它們在構成疑問句時叫疑問詞,引導賓語從句時稱作引導詞。
一是它們和that不一樣,在從句中有含義,擔任相關的句子成分,所以不能省略,另外,它們須放在賓語從句之首,賓語從句必須是陳述句結構。
引導名詞性從句的連線詞可分為三類:
連線詞:that, whether, if, as if, as though***不充當從句的任何成分,但絕不能省略***
連線代詞:what, whatever, who, whoever, whom, whomever, whose, which, whichever.
連線副詞:when, whenever, where, wherever, how, however, why
不可省略的連詞:
1. 介詞後的連詞
2. 引導主語從句和同位語從句的連詞不可省略。
That she was chosen made us very happy.
We heard the news that our team had won.
大部分連線詞引導的主語從句都可以置於句末,用 it充當形式主語。
It is not important who will go.
It is still unknown which team will win the match.
高中英語現在完成時的被動語態知識點
1.現在完成時用法基本概念:表示過去發生的動作對現在造成的影響或結果;或表示過去已經開始,持續到現在的動作或狀態。
2.現在完成時用法基本構成:助動詞have/has+過去分詞 過去分詞的變化規則: 規則動詞的過去分詞由動詞原形加ed構成,不規則動詞的過去分詞 見不規則動詞表***教師給學生影印***
3.現在完成時用法中考考查範圍:
1***yet, already, just, before, never, ever, recently等表示時間的詞作時間狀語,表示過去發生的動作對現在造成的影響或結果 天津中考:
------What are you going to do this weekend? -------I ____yet.
A.haven not decided B.will not decide
C.have decided D.did not decide
2***since, for 引導的時間狀語,表示過去已經開始,持續到現在的動作或狀態
上海中考:The Oriental Pearl TV Tower________thousands of visitors since 1995.
A.attracted B.attracts
C.has attracted D. Will attract
3***this morning, this week, today, now等時間狀語用在現在完成時中
河北中考:-----______Betty this morning? ----Not yet, but she is sure to be here before noon.
A.Have you seen B.Will you see
C.Do you see D.Did you see
4***have/has been to 與have/has gone to 的用法區別
河南中考:Mike ______the bookshop .I have to wait for him.
A.went to B.was in
C. Has been to D.has gone to
4.現在完成時與一般過去時的區別: 現在完成時與一般過去時都表示過去的動作,但現在完成時強調這一動作與現在的關係,如對現在產生的影響、結果等;而一般過去時只表示過去的時間內發生的動作或存在的狀態,就過去的時間方面講,只能與一般過去時連用,而不能與現在完成時連用。 Tom has been busy now.湯姆現在很忙。***過去的動作對現在有影響*** Tom was busy last week.湯姆上星期很忙。***過去的動作對現在沒有影響***
5.判斷正誤:
1***When have you got here? When did you get here?
2*** I have had bought the book two days ago. I have had the book for two days.
3***I have just finished my homework. I have finished my home work a moment ago.
4***Have you ever met an American before? I have met an American last year. 瞬間性動詞***也可叫點動詞或不延續性動詞***表示的動作瞬間即可結束,不能再延續,因此不能與表示延續性的時間狀語連用。
5***I have left Wuhan for ten days. I have been away from Wuhan for ten days. It is ***has been*** ten days since I left Wuhan. Two months has passed since we arrived here. 瞬間動詞--------延續性動詞:應逐一記憶 become-----be begin to study----study borrow-----keep break------be broken buy---have close----be closed come---be here die-----be dead go-----be away get up---be up have got-have join---be in leave---be away lose----be lost marry---be married open---be open
