2、 after, since ,before ,whether as soon as, sothat, suchthat, so that, because ,though/ although ,in order that ,asas 二. 并列连词的用法 并列连词可以分为四类：and 类，表示并列关系， but 类，表示转折关系， or 类，表示选择关系， so 类，表示因果关系。分述如下： （一）表示并列关系的 and 类连词 1. and“和，并且” ，连接并列关系的项 例：She lives and works there. 2. bothand“既也” 例：Both Jim and J

3、ack are Americans. 3. eitheror“或者或者” 连接并列主语时谓语动词一般根据第二个主语的变化而变化。 例：Either you or I am right. 4. neithernor“既不也不” 连接并列主语时谓语动词一般根据第二个主语变化而变化。 例：Neither you nor she is right. 5. not onlybut also“不但而且” 例：I play not only the piano, but also the violin. （二）表示转折关系的 but 类连词。 1. but“但是” 例：He is old, but he l

4、ooks very young. 2. yet“然而” 例：She is young, yet she is very clever. 3. however“然而” 例：He wanted to go there, however, he didnt know the way. 4. while“然而” 例：I am good at swimming while my father is good at skating. （三）表示选择关系的 or 类连词。 1. or“或者，否则” 例：You or I am right. 2. otherwise“否则” 例：Get up at once,

5、 otherwise you will be late for school. （四）表示因果关系的 so 类连词。 1. so“因此，所以” 例：Its raining heavily now, so I have to stay at home. 2. therefore“因此，所以” 例：She cant come here today, therefore you neednt wait for her. 3. for“因为” 例：The days are short now, for its December. 三. 从属连句的用法 （一）引导时间状语从句的从属连句，如 when,

6、while ,as soon as, as, till, until, since, once, after, before 等。 1. when“当时候” ，既可表示时间的“某一点” ，也可表示“一段时间” 。因此主句 和从句有时用进行时态，有时用一般时态。 例：He went to bed when he finished his homework. 2. while“正当时候” ，表示的是“一段时间” ，它引导的从句里的谓语动词不能是点 动词，而应是延续性动词。从句中的行为动词应用进行时态。 例：She was skating while you were riding in the p

7、ark. 3. as“同时” 例：We sang as we danced. 4. since“自从以来” ，从句多用一般过去时，主句多用现在完成时。 例：We havent seen each other since we met last. 5. as soon as “一就” 例：Ill buy it as soon as I have enough money. 注意：当主句是一般将来时态，它引导的时间状语从句要用一般现在时态。 6. till/until“到时，直到才” 。当主句的谓语动词是瞬间动词时，主句要用 否定结构，即 notuntil/till，当主句的谓语动词是延续性动词时

8、，主句可用否定结构， 也可用肯定结构。 例：I waited till you called me. 注意：当主句是一般将来时态时，它引导的时间状语从句要用一般现在时态。 I taught them English until/till they left this school. 7. once“一旦” 例：Once you meet me ,you will find I am a funny person. 注意：当主句是一般将来时态时，它引导的时间状语从句要用一般现在时态。 8. after“在之后” ，before“在之前” 。当 before 引导的从句是过去时态时，主句 一般用过

9、去时态完成时态，但也可以用一般过去时态。 例：We were really very tired after we visited so many places. Before you come here, please call me. （二）引导原因状语从句的从属连词，如 because, for, as, since 等 1. because“因为” ，表示直接原因并且强调造成结果的原因。回答 why 引导的问句时只 能用 because。 例：Because we are late ,we have to hurry. 2. for“由于”其引导的从句并不表示原因，而只是为主句中所说的

10、话提供推断的理 由并加以解释，用以说明前面所说的话。通常主句在前，且 for 前常有逗号。 例：She must be afraid of snakes for she is a girl. 3. since“既然”表示间接或附带的一些显而易见或对方知道的原因，语气比 because 稍弱。 例：Since you like it, take it. 4. as 的语气最弱，多用于日常会话中，它引导的从句常放在主句前。 例：As it is raining heavily, youd better go there by taxi. 【模拟试题模拟试题】 （答题时间：30 分钟） 选择填空：
