3.We don't know the love of our parents _______ we become parents ourselves one day. A.untilB.afterC.whenD.since【答案】A【解析】句意:直到有一天我们成为父母,才知道父母的爱。
本题考查连词。

很明显本句是时间状语从句。

8.(2024重庆卷) 30.—Coach, can I continue with the training?—Sorry, you can’t ______you haven’t recovered from the knee injury.A. untilB. beforeC. asD. unless【答案】C【解析】考查状语从句。
状语从句(一)1. 时间状语从句:1) 由as, while引导时,表示主句和从句的动作同时发生,或一个动作在另一个动作或状态的过程中;2) 由after, when引导时,表示主句动作在从句动作之后;例:1995年1月四级第58题Michael used to look hurt and surprised when ________.A) scolding B) to scold C) having scolded D) scolded本题从句主语与主句主语全都,这种状况下,状语从句的主语时常省略,这是要留意状语从句中的谓语动词应用现在分词还是过去分词。
全句的意思是:麦克尔过去受到责难时,看起来又难过又惊异。
麦克尔是被责难,因而应当用过去分词,所以答案是D。
3) 由before, when引导时,表示主句动作发生在从句动作之前;例:1997年6月四级第44题I had just started back for the house to change my clothes ______ I heard voices.A) as B) when C) after D) whole本题前半部分的意思是:我刚动身回屋换衣服,后半部分的意思是:我听到有人说话。
前半部分用过去完成式,后半部分用一般过去时。
前半部分的动作发生在后半部分之前。
为表达这一情景,前半部分作主句,主句中一般用just,hardly,后半部分作从句,用连接词when引出。
答案是B。
when从句可能表示多种意义,这里它表示一种原来没有预料到的新状况消失。
又是这一新状况打断了主句表示的正在进行的活动,或制止了即将发生的状况。
在这种状况下,主句常用进行式、完成式或be about +inf.之类。
我们来看下面的例题:例:1996年1月四级第45题I felt somewhat disappointed and was about to leave ______ something occurred which attracted my attention.A) unless B) until C) when D) while全句的意思是:我感到有些绝望,刚要离开时,发生了一件事,吸引了我的留意力。

A.in that由于,不能放在主句之前;B.now that 既然,引导缘由状语从句;C.as though好像;D.in case以防.依据句意和上下文可知这里使用now that 引导缘由状语从句。

常见的有以下四种情况:一、条件状语从句的主句是一般将来时,那么从句常常用一般现在时如:When I grow up, I’ll be a nurse and look after patients我长大后要当一名护士,照顾病人二、如果主句是祈使句,那么从句通常要用一般现在时如:Don’t laugh a t me when I make a mistake.我犯错误的时候不要笑话我。
三、如果主句是含有情态动词的一般现在时,根据需要从句多用一般现在时如:You should be quiet when you are in the reading room在阅览室时应保持安静四. 如果if的条件状语从句遇到变换间接和直接时 , 祈使句应用not to....如; She said not to close the window常见的时间状语从句的连词有:as soon as,when,while ,as,until等。

用作副词,修饰形容词和副词。
主要结构有:1.so +adj.+a/an +可数名词单数+that从句;2.so+adj./adv.+that从句;3.so+many/few/much/little+复数可数名词+that从句such(adj.)表示“如此”“这样”的意思。
用作形容词,修饰名词。
主要结构有:1.such+a/an+adj.+单数可数名词+that从句;2.such+adj.+不可数名词+that从句;3.such+adj.+复数可数名词+that从句。
所以选B。

本句是时间状语从句,四个选项都可做引导词;根据Leonardo didn't win an Oscar和答语中的but he never gave up.,结合句意结构和语境,可知until符合句意,故选D。
8.— What were you doing ______ I knocked at the door?— I was sleeping.A.unless B.onceC.when D.while【答案】C【解析】【详解】试题分析:句意:-我敲门时,你在做什么?-我在睡觉。

本题表示“当……时”,knock是非延续性动词,故选C。
考点:考查连词辨析。
9.________it’s Sunday tomorrow, we have to go to school.A.Though B.Since C.As D.Because【答案】A【解析】【详解】句意:尽管明天是星期天,我们不得不还要上学。
考查从属连词。
根据后文we have to go to school我们不得不去上学。
可知前面从句应表示让步状语。
故选A。
10.— Do you think Jack will catch up with us?— I believe so._______ he loses himself in computer games.A.If B.Unless C.Or D.But【答案】B【解析】【详解】句意:—你认为杰克会赶上我们吗? —我认为会,除非他沉迷于电脑游戏。
A. If如果;B. Unless除非;C. Or否则;D. But但是。
根据本题语境,可知,回答为如果他不沉迷于电脑游戏,他就能赶上我们,如果不,即为除非。
故选B。

他说世界上没有水就没有生命。
A. if如果;B. unless除非,如果不;C. although尽管。
如果没有水。
世界上没有任何东西可以生存。
结合句意可知,此句是unless引导的条件状语从句,unless=if not,故答案为B。
【点睛】if引导的条件状语从句,当主句是一般将来时,从句用一般现在时表示将来的含义,就是我们常说的“主将从现”,unless也有类似的用法,unless作为连词引导条件状语从句时,可以表示“如果不”或“除非”,unless=if not,如:We will go to the park if it doesn’t rain tomorrow. 可以改写为:We will go to the park unless it rains tomorrow.12.In summer, food will go bad quickly ________ we put it into a fridge.A.if B.unless C.as soon as D.while【答案】B【解析】【详解】句意:夏天,除非我们把食物放进冰箱里,否则食物很快就会变坏。
A. if如果;B. unless除非;C. as soon as一……就;D. while正当……的时候。
根据生活常识,在夏天只有放在冰箱里的食物才能保证不变质,unless除非,如果不,相当于if not,引导条件状语从句,故答案为B。
