v 倍数的表达：如twice(荔枝妹经常做错这类型的题 所以稍微补充一下 )

　　1. twice as +adj./adv +as…(注意修饰的名词是否可数)

　　如twice as much/many as…

　　2. twice可直接跟名词(也可为代词，如that)

　　3. twice+what从句

　　4. twice +adj.+than… (adj要比较级，如twice more than)

　　Ø not only…but also (参考一月JJ总结整理&皮皮总结)

　　1. not only…but (also)… 表示的关系是递进，其中also可以省略。单独出现but also，表转折。

　　2. 正常语序中，not only…but (also)…连接两个相对称的并列成分，要注意平行，主语与谓语单复数一致。

　　3. 连接两个主语时，谓语动词要和与其最近的主语保持人称和数的一致。

　　例Not only the students but also their teacher is enjoying the film.

　　4. 当not only…but also…连接两个分句且not only提在句首时，not only引导的句子倒装，里面的每一个动词都要部分倒装，而but also分句不受影响;

　　另外，倒装的时候，but also中间有时会加一个主语，是可以对的。

　　Not only does the sun give us light, but also it gives us heat.

　　Not only did he speak English correctly, but he also speaks it fluently.

　　5. 特别提醒：留意句子逻辑意思，区分句子是否真的需要not only but also表递进。同时同一个分句里面若同时有also和as well，意义重复，不正确。

　　鉴于最近的狗太少了，所以整理的平行的知识点有点杂乱。希望大家考完试可以多回忆一下具体考的是什么平行结构，这样才好整理出真正能帮到大家的语法JJ。这里平行的知识点感谢2月的JJ整理者荔枝!
