问题 The old radar-and-radio system is becoming______, as new digital technology provides airline pilots with satellite signals to aid in navigation.
选项 A、absent
B、missing
C、without
D、obsolete
答案D
解析 空格内应该填入一个形容词，作为其前becoming的表语。因此可以排除用作介词的(C)without。由as后的内容可以推断，短句要表达“陈旧的雷达无线通信系统已经报废了”的意思。因此表示“脱离时代的，旧式的，无法使用的”这一意思的(D)ob—solete最为合适。
