5> 在将来时的从句中常用when, 且从句必
须用一般现在时。
You shall borrow the book when I have
finished reading it. 6> when还用在表示 “一……就……”的
句型中。 Hardly/Scarcely had I entered my room when the telephone rang.
原因状语从句中应注意的问题
as, because, for, since 的区别 1> as作为从属连词引导原因状语从句时,语气 不如because 强烈。它引导的从句常放在 句首, 说明原因, 后面的主句则说明结果。 2> because 引导从句时, 语气最强, 直接回答 why的问句。她引导的句子是语意中心所 在, 一般在句后。 (最强答why）
当主从句动作同时发生, 且从句动作
为延续性动词时, 三者可互换。 When/While/As she was making a phone call, I was writing a letter.

高中英语When引导的三类从句_共19张PPT_
“when she thinks back to when she first met her husband”里边套有另一个从句 “when she first met her husband”。 第一个when从句不难理解,它是一个时间状语从句,when可译成“当„„时”。 第二个when从句较为特殊:从结构上看,这个 when从句是作介词to的宾语,所以是一个宾语 从句;从when的意义上看,这里的when没有疑问的意味,而是相当于说“the day when”。所 以从句“when she first met her husband”可以改写成一个定语从句 “the day when she first met her husband”,表示“第一次遇到她丈夫的那天”。
如何区分when引导的名词从句与时间状语从句
其实,区分两者的方法很简单,大家只需要判断when从句在主 句中充当何种成分即可:如果when从句在主句中充当主语、表 语或宾语,它就是名词从句(分别属于名词从句中的主语从句、 表语从句或宾语从句);否则,when从句便是时间状语从句(同位 语从句除外)。
由此可见,翻译when引导的名词从句时,when的含义需依 具体的语境而定,有时可译成“什么时候”,有时可译成 没有疑问意义的表达。 需要指出的是,当when引导时 间状语从句时,when通常译成“当„„的时候”或“在„„之 后”。
我们再来看下面这句话: 3. To her, the arguments about little things and other obstacles she and her husband face are f

中考英语语法之状语从句 )(共23张PPT)
八、让步状语从句 定义：让步状语从句，是指状语从句中的一种，其本身也是状语从句。一般翻译为“尽管……”或 “即使……”，就是我们日常生活中用的“退一步说…”的感觉。 //引导词// though/although/as（虽然，尽管） even if/though（即使，尽管） whether/no matter whether...or(not)（不管...是否，不管是...还是） //注意// 1. though, although,as的区别 A. though, although的主句中可以用 yet, still, nevertheless,但不可使用but。 B. though引导的从句可以倒装，也可以不倒装； as引导的从句必须倒装； although引导的从句不能倒装。
as 1. 表示“当...时候”，强调同时发生，不指先后。 2. 说明两种正在发展或变化的情况，表示“随着”，表示时间的推移。 3. 表示“一边...一边...”。 4. 强调两个动作紧接着发生。 5. 表示“虽然，尽管”。 6. 其他含义“正如，正像”，“作为”，“由于，因为”
before 1. 一般意为“在...之前” “...才”，“...就” “还没有...”“免得”“不知不觉” “宁可，宁愿”，“否则，要不然”。
//注意// for也可以表示原因，属并列连词，但不是说明直接原因，而是对某种情况加以 推断，用于表示补充说明理由。
三、地点状语从句 定义：地点状语从句表示地点、 方位。 引导词：where, wherever 1. 地点状语从句由where, wherever引导。 //注意// where与wherever的区别：where表特定的地点，而wherever表示非特定的地点。 wherever=to/at any place where 2. 地点状语从句与定语从句的区别 where引导定语从句时，从句前应有一个表示地点的名词作先行词； 而状语从句前则无先行词。
