【合作学习，组内交流】2.■adj.和adv.的修饰词

哪些词修饰原级，哪些词修饰比较级，哪些词既可以修饰原级也可修饰比较级?用于修饰原级的词：very,so,too,quite,enough(后置）,pretty,alittle

用于修饰比较级的词：alittle,abit,alot,much,even,far既可以修饰原级也可修饰比较级：alittle,abit

more能放在比较级前修饰比较级吗？

■注意：

1.在含有连词than的比较级中，前后的比较对象必须是同一范畴，即同类事物之间相比较。例：Itisbettertogivethantoreceive.

2.要避免将主语含在比较对象中。eg.ShanghaiislargerthananyothercityinChina.(theothercities)

3.要注意冠词的使用。形容词后有名词时，前面才有可能有冠词。

例：Whichisthelargercountry,CanadaorChina?

4.最高级常用于“the+最高级+比较范畴”结构，表示“三者或三者以上（人或事物）比较。比较范畴可以用“in/of+名词的复数形式或代词的宾格”表示。若“范围”是与主语同范畴的词，用of；若为不同范畴的词，则常用in。例：Thispictureisthebestinthehall.
