many
1.a great many（很多）比a good many（相当多）语气重。两种表达方式后面直接接名词，不用of，如可以说a great（或good）many books。不可说a great（或good）many of books。但在a great（或good）many of my（或his，these等）books等表达方式里的of当然不可省去。
2.a many（=a great many）现在不算正当。
3.many a作many times a...（许多的，一个又一个的）解，后面接单数名词，那动词也是单数形式。例如：Many a man has tried it before.
4.下面各句都不合习惯：
- The books are many here.（该改作The books are plentiful here或There are many books here。）
- The books are a great（或good）many here.（该改作There are a great［或good］many books here。）
- His books are many.（该改作He has many books。）
- His books are a great（或good）many.（该改作He has a great［或good］many books。）
The books are many和His books are many有时可以说，但通常含有“虽然多”或“确实多”的意思。例如：
- The books are many, but the pictures are few.
- His books are many, though his pictures are few.
- The books are many, but they are all poorly selected.
- His books are many, though they are all poorly selected.
5.I don't write many letter是“我写信不多”。I don't like many wines可能是“有许多种酒是我所不喜欢的”，但也可能是“我不喜欢许多种酒（只喜欢二三种酒）”。
