練:(1)when i got off the crowded bus,i found my pocket and the disk in it with the important documents gone.
a.picked b.stolen c.missing d.lost
提示:從搭配關系來看，應該用pick，因為pocket習慣搭配pick，但wallet等不搭配pick，要和steal等連用。
答案:a
(2)when i entered the playground,i found a lot of girls volleyball excitedly.
a.play b.played c.playing d.plays
提示:從句子結構看，選項作賓語補足語，排除d項；girls與play volleyball之間有主動關系，且當時正在進行，故選c項。
答案:c
