[即境活用]
5.after having followed the thief for half an hour，they________him in a large department store.
a.lost the sight b.caught sight
c.out of sight d.lost sight of
解析：選d。考查動詞搭配。lose sight of“看不見”，為及物動詞短語；而out of sight雖意為“看不見”，但它不能獨立作謂語；a、b表達形式有誤，故d項正確。
6.for miles around me，there was nothing but a desert，without a single tree or plant ________.
a.on earth b.for instance
c.in sight d.at place
解析：選c。句意：我周圍幾英里范圍內除了沙漠什么都沒有，放眼望去甚至沒有一棵樹或植物。in sight在視野內。on earth“究竟；在世界上”；for instance“例如”；at place不是固定用法。
