题1：Since 1995, ______ people call the Year of the Internet, the world has turned flat thanks to the net work.. A. which B. when C. in which D. by which time 答案：A 详解：______ people call the Year of the Internet为定语从句，其先行词为1995。此处1995为call的宾语，所以选which。
题2：The old town has narrow streets and small houses ______ are built close to each other. A. they B. where C. what D. that 答案：D 详解：_____are built close to each other 是定语从句，其先行词为narrow streets and small houses。从句中缺少主语指物，因此用that。句意：这个老城镇拥有建的彼此靠近的狭窄的街道和狭小的房屋。
题3：We went to the West Lake yesterday, , not surprisingly, was crowded with visitors from all over the world． A. where B. which C. that D. when 答案：B 详解：第一个逗号之后是一个非限制性定语从句，其先行词为the West Lake。把从句中的插入语not surprisingly删去之后，就可明显地看出从句缺少主语，所以选which。
题4：Between the two parts of the concert is an interval, _______ the audience can buy ice-cream. A. when B. where C. that D. which 答案：A 详解：_______ the audience can buy ice-cream是定语从句，其先行词为interval。因为从句缺少时间状语in the interval，所以选when。
题5：The time is not far away ________ modern communications will become widespread in China’s vast countryside. A. as B. when C. until D. before 答案：B 详解：因为先行词是the time，且在定语从句中作状语，所以用when引导。此题的先行词与定语从句被主句谓语分开了，要善于辨别。
