This book will be ___in your studies. A.of helpful B.of great use C.great importances D.with

This book will be ___in your studies. A.of helpful B.of great use C.great importances D.with car是选b吗为什么

Answer 1

是应该选B
因为把B选项代入句子中，从语法和翻译的角度而言都是能说得通的：This book will be of great use in your studies.这本书将会对你学业大有用处。
be of great use是固定搭配，意思是“大有用处”
而A选项中应该改为of help,因为of之后要接名词，不是形容词
C选项少一个of，应该是 of great importance
而D选项从含义和语法上都讲不通
