Question

They promised to develop a software package by the end of this year, ________ they might have.

A．however difficult	B．how difficult
C．whatever difficulty	D．what difficulty

Answer 1

C

和difficult，difficulty搭配的狀語從句的連詞分別是however difficult, whatever difficulty, 根據(jù)they might have 可知，此處句型為sb have difficulty (in) doing something，因此排除A.B。句意為他們承諾在今年年底要開發(fā)一個軟件包，無論可能會有什么樣的困難。無論有什么樣的困難，即whatever difficulty they have 或者no matter what difficulty they have,或者however difficult it might be, no matter how difficult it might be. 排除D項。故選擇C項。
