{01}We have just heard a warning on the radio _____________ a typhoon may be on its way．

A.what

B.when

C.which

D.that

解析：             
试题分析： 考查同位语从句。句意：我们在收音机听到一个警告，台风即将来临。A warning后面跟着一个同位语从句，由that来引导说明警告的内容，on one’s way 即将来临；         
考点 : 考查同位语从句
本题选D。
{02 ________ you are supposed to do ________ you don"t like a thing is change it. Don"t complain.

A.That; why	B.What; when
C.What; where	D.That; how

解析：B　句意：当你不喜欢一件事情时，你应该做的是改变它。不要抱怨。“________you are supposed to do”为主语从句，该从句缺少宾语，表示“事物”且语境中并无选择含义，故用what引导；“________you don"t like a thing”为时间状语从句，作are supposed to do的状语，说明其时间，故用when引导。因为主语从句“What you are supposed to do”中含实义动词do，故is后的表语需为省去不定式符号的不定式，故change作表语。
本题选B。
