My father often_plays____(play)basketball on computer My uncle____(play)sports every day
Bill_doesn't play__(not play)computer games on weekdays.
Let`s_play__(play)games
I_don't have___(not have)a baseball怎么做卅1句子考察的是一般现在时。My fathe是第三人称单数，所以play要加s。My uncler同理。2还是一般现在时，Bill为第三人称单数，所以助动词do变does。3祈使句Let's do sth.要用动词原形。4一般现在时，主语是第一人称，所以助动词do不变。
