Question

It's ________ book that I keep ________ it in my free time.

A. so an interesting; read
B. such an interesting; reading
C. so an interesting; reading
D. such an interesting; read

Answer 1

答案B
点拨：此题考查so和such在用法上的区别。so和such都表示“如此，这样”，但他们的位置不同。“such+a /an+形容词+名词单数”这个结构可改成“so+形容词 +a /an+名词单数”，但“such+形容词+不可数名词”的结构不可改变。另外“so many /much+名词”是固定结构，不能用such; keep doing sth. “一直做某事”。
