狀語從句
單擊此處添加標題
時間狀語從句
1.when、while和as的用法
when “在……時候”,可與延續性動詞或短暫性動詞連用;從句動作可以發生在主句動作之前、之后或與主句動作同時發生
while “在……期間;與……同時”,一般只可與延續性動詞連用,從句動作與主句動作同時發生
as “當……時;隨著”,常與延續性動詞連用,從句動作與主句動作同時或幾乎同時發生
例句:When I met my boss, I seemed very nervous.
One Sunday morning, while the children were reading, I stepped to the doorway of the yard to take a break.
高考題常見陷阱:
While I got home, it began to rain.
When I got home, it began to rain.

got 是短暫動詞
真題實戰:
1. (2023浙江卷)_______ I was about to leave, it began to rain heavily.
2. (2021全國I 卷) _________ the discussion was going on, someone took a photo secretly.
做題方法:
1. 看從句動詞----是短暫性還是延續性
2. 是否需要強調“同步進行”或“對比”
When
While
2.before與since的用法
(1)before表示“在……之前;還未……就……;還沒來得及……就……”,常用于以下句型。
It will be+一段時間+before... 多久之后才……
It won't be long before... 不久之后就……
It was+一段時間+before... 過了多久才……
例句:It didn't take long before he finished his task.(翻譯句子)
(2)since表示“自從……”,其引導的從句在句中作狀語時,主句常用現在完成時或現在完成進行時,從句常用一般過去時。
since表示“自從……以來”,常用于“It is/has been+時間段+since從句”句型。該句型表示“自從……已經多長時間了”,從句的時態常用一般過去時。
3.till、until和not...until...的用法
(1)until/till意為“直到……為止”,表示某動作一直延續到某時間點才停止,此時主句謂語動詞是延續性動詞且為肯定形式。
例句:We will explore every solution till/until we find an answer. 我們要探尋一切解決方案,直到找到答案為止。
(2)not...until...“直到……才”,表示某動作從某時間點開始發生,主句謂語動詞是短暫性動詞。
We didn’t realize the danger until it was too late.
4.表示“一……就……;剛……就……”的常用表達
(1)表示“一……就……”的表達有as soon as、immediately、directly、the moment、the minute、 the instant、instantly等。
例句:(2023·新高考Ⅱ卷)I promised to take care of Tiffy and call them as soon as we got to Kansas City. 我答應照顧Tiffy,一到堪薩斯城就給他們打電話。
(2)表示“剛……就……”的表達有no sooner... than...、 hardly/scarcely...when...等。該結構中,主句謂語動詞應用過去完成時,而than與when引導的從句謂語動詞應用一般過去時。此外,如果no sooner、hardly、scarcely等置于句首,主句應部分倒裝。
例句:She had no sooner said it than she burst into tears.
=No sooner had she said it than she bursy into tears.
Scarcely had the game started when it began to rain.
考點2 讓步狀語從句
1.although、though、while等常引導讓步狀語從句。
Though/Although/While regular exercise is very important, it's never a good idea to exercise too close to bedtime. 盡管定期鍛煉很重要,但臨睡前鍛煉絕不是個好主意。
2.as引導的讓步狀語從句要用倒裝結構,即將從句中的表語、狀語或動詞原形置于句首;若表語是單數名詞,前置時要省略冠詞。此時as可與though互換。
Child as/though he is, he has helped me a lot.他盡管是個孩子,卻幫了我很多。
3.“特殊疑問詞+ever”引導讓步狀語從句,意為“無論……”,可與“no matter+特殊疑問詞”結構互換。
4.whether... or...引導讓步狀語從句時意為“不論……還是……”。
考點3 條件狀語從句
1.條件狀語從句的常見引導詞:if、unless(=if... not)、so/as long as (只要)、on condition that (條件是)、if only、provided that (如果)、in case (萬一;如果)、suppose/supposing that (假設;如果)、assuming that(假定;假設)、unless等。
2.條件狀語從句的時態:在條件狀語從句中,常用一般現在時表示將來的含義;用現在完成時表示即將完成的情況;用一般過去時表示過去將來的含義。
考點4 地點狀語從句
地點狀語從句通常由where、wherever引導。
例題:1. Molai built at the top of each sapling (幼樹)a bamboo platform, __________ he placed earthen pots with small holes to collect rainwater.
2. ―Tom doesn't seem so enthusiastic as he was two years ago.
―Yes. He's really reached a point in his career ___________he has to decide what to do next.
3. I write my motto _______I can see it easily.
考點5 原因狀語從句
because: 表示直接原因,語氣較強,能回答由why提出的問句
as :常表示顯而易見的原因,語氣較輕
in that(因為)、now that(既然;由于)、since(既然):表示雙方都知道的原因,語氣較弱
for : 表示推斷的理由,是對前面分句的內容加以補充和說明。
例句:As Monday is a national holiday, all goverment offices will be closed.
It rained last night, for the ground is wet this morning.
考點6 結果狀語從句

2.
3. so that
so +

many/much/few/little +名詞
+that 從句
such +
+that 從句
adj. +a/an+可數名詞復數/不可數名詞
a/an +adj.+可數名詞單數
a lot of/lots of + 名詞
注意:當“so+adj./adv.”或“such+n.”置于句首時,主句要部分倒裝。
例句:So excited am I that I vannot wait to do sth.
考點7 目的狀語從句
in order that/so that 表示“以便……;為了……”,它們引導的狀語從句中常用情態動詞
in case (that)表示“以防出現某種情況”
例句:(2023·全國甲卷)It's a surprise they haven't managed to grow square ones so that they can pack them easily. 令人驚訝的是,他們沒有設法種植方形的,這樣他們就可以方便地把它們打包。
考點8 方式狀語從句
引導方式狀語從句的有as if、as though等。
as if/as though引導的方式狀語從句與事實相反時,從句通常用虛擬語氣;與現在的情況相反時,用一般過去時;與過去的情況相反時,用過去完成時;與將來的情況相反時,用“would/could/might+動詞原形”。
狀語從句的省略
狀語從句的省略,是高考中經常考察的點。
狀語從句什么時候可以省略?
當從句的主語和和主句的主語一致,并且從句謂語中含有be 動詞時,可以將主語和be 動詞同時省掉。
例句: when he was reading, he took notes.
When reading, he took notes.
Though she was tired, she continuing walking.
Though tired, she continuing walking.
