Question

________ nearly all behavior is learned behavior is a basic assumption ________ has been put forward by social scientists.

A．What; that	B．That; what
C．What; what	D．That; that

Answer 1

D

D　句意：幾乎所有的行為都是學(xué)來的行為是社會學(xué)家提出的基本設(shè)想。“________nearly all behavior is learned behavior”為主語從句，該從句不缺任何成分，故用that引導(dǎo)；“________has been put forward by social scientists”為定語從句，先行詞為assumption，將先行詞代入定語從句后為：The assumption has been put forward by social scientists.由此可見先行詞在定語從句中作主語，故用that引導(dǎo)。
