请问not only...but also...的用法：下面的两个句子哪个对?还是两个都对?(要有把握才能答哦!)1、You must not only wash the dishes but also sweep the floor.2、You not only must wash the dishes but also sweep the floor.这个猜测对吗：not only but also的主句若为同一动词第二个就可省掉,若为两个不同的动词,则不能省掉：如：I not only speak English very carefullu,but very clearly as well.You must not only wash the dishes but sweep the floor as well.not only but also 是否和not only but as well意思和用法是一样的?

也可以写成强调句Not only u must wash the dishes but sweep the floor

1中的第1句对 后面的那句的must造成歧义
对
可以

Not only do I speak English very carefully, but very clearly as well.
Not only must you wash the dishes but sweep the floor as well.

1.第一句对,第二句错
2.是这样的
3.意思相同,用法也类似.also放在句中,as well放在句尾.

1.第一句正确.
2.是省略动语,而不是also,not only.but also 不动词短语,固定搭配．
3．Ont only...but also不但．．．而且．．．．not only...but as well,不仅．．．但这样更好．不一样．

1、not only…but also…的用法
用于连接两个表示并列关系的成分，着重强调后者，其意为“不仅……而且……”；其中的also有时可以省略。如：
She not only plays well, but also writes music.
她不仅很会演奏，而且还会作曲。
He not only writes his own plays, he also acts in them.
他不仅是自编剧本, 还饰演其中的角色。
Not only men but also women were chosen.

He works not only on weekdays but on Sundays as well.
他不仅平时工作，星期日也工作。
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。
说明：若连接两个成分作主语，其谓语通常与靠近的主语保持一致。如：
Not only you but also he has to leave. 不只是你，他也得离开。
若连接两个句子，not only后面的句子要用倒装，如：
Not only did he speak more correctly, but he spoke more easily. 他不仅说得更正确，而且讲得更不费劲了。
2、neither…nor…的用法
用于连接两个表示并列关系的名词，用于否定两者，其意为“既不……也不……”、“……和……都不”。如：
It’s neither too cold nor too hot.
天气既不太冷也不太热。
Neither boys nor girls are interested in it.
男孩子和女孩子对此都不感兴趣。
说明：通常应连接两个相同性质的句子成分，但有时后一成分可能省略与前一成分相同的词。若连接两个成分作主语，其谓语通常与靠近的主语保持一致。如：
Mary neither likes maths nor (likes) history.
玛丽既不喜欢数学也不喜欢历史。
Neither Jim nor Jack was at home.
吉姆和杰克都不在家。
但在非正式文体中也可一律用复数。如

Neither Jim nor Jack were at home.
吉姆和杰克都不在家。

Either you or I am wrong. 不是你错了就是我错了。
Are either you or I wrong? 是你错了还是我错了?
说明：通常应连接两个相同性质的句子成分，但有时后一成分可能省略与前一成分相同的词。若连接两个成分作主语，其谓语通常与靠近的主语保持一致。如：
You can either have tea or coffee.
你喝茶也行，喝咖啡也行。
