1、九年级中考英语语法讲解.连词并列连词either.-or用法either.or.主要用于表示选择，其意为要么.要么.*或者.或 者.，用于连接两个性质相同的词或短语。如：You can have either this one or that one.你拿这个或那个者S可以。You must either go at once or wait till tomorrow.你要么马上走，要么等到 明天。We can finish the work either this week or next week.不是这星期就是下星 期我们就可完成这项工作。在具体使用not only.but also.
2、时还应注意以下几点：1. either.or.连接两个成分作主语时，谓语动词通常与其靠近的主语保持一 致。如：Either you or I am to go.你或我必须有人去。Either he or you are right.要么他对，要么你对。但在非正式文体中，有时也会一律用复数谓语。如：If either David or Janet come, they will want a drink.大卫或珍妮特来的话， 是会要喝酒的。2. either.or.除可连接两个词或短语外，有时也可连接两个句子。如：Either you must improve your work or I sh
3、all dismiss you.要么你改进工作, 要么我就辞退你。Either youll leave this house or III call the police.你要是不离开这座房子， 我就叫警察来。3. either.or.的否定式可以是not eitheror,也可以是neithernor。 如：He didnt either write or phone.=He neither wrote nor phoned.他既没写信 又没打电话。注意，正如不能说either.not 一样（但可说not.either）,英语习惯上也不说 either.or.not,如不能说：Either
4、he or his wife hasnt come.可改为：Neither he nor his wife has come.并列连词not only.but also.的用法not only.but also.表示不仅而且冰既又，用于连接两个性质相同 的词或短语。如：Not only men but also women were chosen.不仅仅是男的，女的也有被选 中的。We were not only hungry, but also tired.我们不但饿了，而且也累了。She likes not only music but also sport.她不但喜欢音乐而且喜欢运动。S
5、he not only plays well, but also writes music.她不仅彳艮会演奏,而且还会 作曲。We go there not only in winter, but also in summer.我彳门不仅冬天去丹的L, 而且夏天也去。另外，在使用not only.but also时还应注意以下几点：1. 有时可将but also分开用，即将but视为普通的并列连词，用于连接两个 句子，然后将also用于句中（用谓语动词用在一起）。如：Hes not only very fast, but hes also got marvellous technique.他不
6、仅彳艮快, 而且技术高超。2. 该结构中的also有时可以省略，或将also换成too, as well （置于句末）。 如：He not only washed the car, but polished it too as well.他不仅冲洗汽车, 而且还擦拭了它。His name is known not only in Japan, but in China.他不仅在日本出名，而 且在中国也出名。3. 有时因为语境的需要，not onlybut also也可能用于连接两个性质不同 的词或短语，但这多半因为承前省略的原因。如：He not only goes to work on we
7、ekdays, but also on weekends.他不仅工作 日去上班，在周末也去上班。句中的not only后接的是谓语goes to,而but also后接的却是状语on weekends,可视为but also后承前省略了谓语动词goes to worko4. 当not only.but also连接两个主语时，谓语动词的数原则上与其相近的 主语保持一致。如：Not only the students but also their teacher is enjoying the film.不仅学生 们在欣赏这部影片，他们的老师也在欣赏这部影片。5. 为了强调，可将not only
8、置于句首，此时其后的句子通常要用部分倒装的 形式。如：Not only has she been late three times, she has also done no work.她不仅 仅迟到了 3次，她还没干一点活。Not only do they need clothing, but they are also short of water.他们不但 需要衣服，而且还缺水。有时也可见到不倒装的情形，此时主要见于but also后接省略结构的情况（省 略只剩下主语）。如：Not only my mother was unhappy, but Marian, too.不仅我母亲不快乐，
9、玛 丽安也不快乐。but与however的用法区别两者均可表示转折或对比，意为但是、可是、然而”等，但有区别：1. 表示转折时，but是连词。如：He is young but very experienced.他虽年轻，但经验很丰富。He has three daughters but no sons.他有 3 个女儿，但没有儿子。He likes sports, but his wife likes music.他喜欢运动，而他妻子则喜欢音乐。2. however表示然而、可是时，有的词书认为它是连词，有的词书认为 它是副词。之所以将其视为副词，也许是因为像许多副词一样不仅能位于句首， 而
10、且能位于句中（注意前后使用逗号），甚至句末（注意其前也用逗号）。如：Later, however, he changed his mind.可是他后来改变了主意。He hasnt arrived. He may, however, come later.他还没有至L 不过他等会 儿可能会来。He said that it was so; he was mistaken, however.他说情况如此，可是他 错了。注：以上各例中的however不能换成but,但可用but来改写。如：He said that it was so, but he was mistaken.他说情况如此，可他错了。
11、3. 当连接两个句子时，其前通常应用分号，或另起新句。如：Its raining hard; however, I think we should go out. / Its raining hard. However, I think we should go out.雨下得很大，但我想我们还得出去。注：上例中的however不能换成but,但可用but来改写(注意所用标点 的变化)。如：Its raining hard, but I think we should go out.比较so和such其规律由so与such的不同词性决定。such是形容词,修饰名词或名词词 组，so是副词,只能
12、修饰形容词或副词。so还可与表示数量的形容词many, few, much, little连用，形成固定搭 配。such + a(n) + n. such + n. (pl.) such +n.(pl.) such +n.不亩数so + adj.so + adj. + a(n) + n. so + adj. + n. (pl.)so + adj. + n.不可数so foolishso nice a flowerso many/ few flowers so much/little money, so many peoplesuch a foolsuch a nice flower such
13、nice flowers such rapid progress such a lot of peopleso many已成固定搭配，a lot of虽相当于many,但a lot of为名词性的, 只能用such搭配。so.that与such.that之间的转换既为so与such之间的转换。英语连词用法集锦一.并列连词和连词短语并列连词用来连接平行的词、词组或从句。常见的连词有and ,but ,or ,so ,both.and , either.or,neither.nor, not only. but also 等。1. and1) .and表示 、和、且在肯定句中连接并列的成分。He
