Question

Never mind. You've just caught ________ a cold.

1. A.
   a bit
2. B.
   a bit of
3. C.
   a little
4. D.
   a little of

Answer 1

B
a bit和a little常可换用，但在修饰名词时有区别：a little可直接修饰不可数名词，而a bit则需与of搭配。如：a little money / a bit of money；a little cold / a bit of a cold（有点感冒）。如果a little与of搭配，则a little用于预指后文，即of后的名词为特指。如：I've only read a little of the book.（这书我只读过一点。）
