saw 后面也可以看成一个宾语从句，如果看成宾语从句的话，后面的谓语应该用过去进行时，即were doing ，和主句的时态一致。
如果D改为 were doing ，就可以选择D。
选择B
playing
表示当时正在发生的动作或状态
I saw some boys playing basketball on the playground when I passed by just now.
刚才我经过的时候我看见一些男孩子们在操场上打篮球。
选D，缺的是非谓语动词，所以用现在分词，没发现没有 do 么，如果出现了会很难办，因为用do也马马虎虎
选择D。考查非谓语动词的用法。感官动词see的复合结构用法如下：
see sb. doing sth. “看见某人在做某事”（强调动作的片段）
see sb. do sth. “ 看见某人做某事” （强调动作的全过程）
由于上文的时间状语从句强调动作片段，所以选择D。
答案选D，see someone doing
肯定是d。see …doing…
B

隰县18391124626： 1.when i walked past her room,I heard her ()an english songs A,singing B,was singing c,sang - ？
漫治扶济： 1.singing是现在分词作宾补,表示动作在当时正在发生着,强调进行性,是因为有时间状语when i walked past her room在体现,就是这个时间下,宾语在发生的动作;而B是谓语动词形式,这里要用非谓语动词;因为句中已经有了谓语动词的heard,另外,her也不是主语2.scared本身是一个形容词,做了表语,are是复数的、一般现在时的系动词.
隰县18391124626： I saw an old man - ___(lie)on the ground when I walked past.这里为什么要用lie的过去分词 - ？
