一、 2020年全国Ⅰ卷的考题
Because the moon's body blocks direct radio communication with a probe, China first had to put a satellite in orbit above the moon in a spot 63 it could send signals to the spacecraft and to Earth.
第63空, 对不少考生来说都是 "拦路虎". 定语从句中先行词为时间或地点名词, 关系词是用代词还是副词, 需要看它在从句中充当的成分来决定. 本题先行词为spot, 在定语从句中充当地点状语, 63题应该填where.
