如题所述
只有在一般现在时里才存在单数第三人称加S的情况 比如：He liks watching TV (他喜欢看电视)
在一般过去时里要用动词的过去式，也就是加ed，此时不需考虑单数第三人称的情况。如：he liked watching TV
做题时先要判断好时态，如需用一般现在时再考虑单三情况。

三单和过去式并存时 只看过去式
He went to the beach yesterday.他昨天去了沙滩。
虽然主语是he 属于三单,但是因为是过去式 所以直接把goes变为went 但是不能再在went上加s

我没碰到过第三人称单数和过去式同时使用的情况，三单一般现在式，过去式加ed，分开使用就成。

还是加ED。
