the missing boys were last seen 空格 near the river; a:playing ; b:to be playing,
我这儿的答案是b,
the missing boys were last seen 空格 near the river; a:playing ; b:to be playing,我这儿的答案是b,
选择A
理由 see somebody doing 是固定结构,无论see用的主动形式还是被动形式都用doing；
答案可能依据的是see sb do由主动变被动时要加上不定式符号to.
供参考.
a
b
答案应该选a:playing
see后面接双宾语有三种用法，see sb do sth, see sb doing sth, see sth done sth。这句话的意思是小孩最后被人看到是在河边玩，应该是强调一种他正在玩的时候被看到的状态，因此选进行时playing。
playing
答案错了
see sb. doing:看见某人在做某事
see sb. do sth看见某人做了某事
变被动后为Sb was seen doing (to do)不会出现to be doing
