It is known to us __________ it was not until 1938 ________ the first colour TV programme began to be broadcast in the world.
A．that, whichB．/, /C．that, thatD．which, that
C

試題分析：第一空是that引導的主語從句，第二空是強調(diào)句型it is...that...；句意是直到1983年世界上第一個彩色電視節(jié)目播出，是眾所周知的。
點評：此題較易，主要考查that引導的從句，關鍵是句子成分分析，一個是主語從句，一個是強調(diào)句型。
