是不是need doing的主语是人?

是不是need doing的主语是人? need doing 的用法 need to be done的问题主语（人） need/want/require to do 主语（物） need/want/require doning那need to be done前面是人还是物啊? 关于cost的用法...cost的主语一定是doing sth 或者是sth.不可以是人,那么It 这个形式主语做主语行吗? 谢谢请就doing sth 或者是sth造两个句. the room needs to be big enough for three people物是主语不应该是need doing吗? like doing sth中主语是第三人称单数的话,like是不是变成likes? require to do 还是 require doing我知道,主语是sth时,require doing 等于 require to be done.我想问的是：当主语是人时,又没有被动含义时,require的用法是否像need一样,是 sb require to do sth比如“我需要休息” need to do和 need doing的区别.是人和物的区别吗? need do/need to do/need doing的意思 英语there is no need doing还是to do 答案给的是doing 为什么 need的实意动词和情态动词的用法区分（后加物）need 作为情态动词,后接动词原形,一般用在疑问句和否定句中作为实义动词,人作主语时后接to do ； 物作主语时后接doing 或 to be done It's cold ,you need doing What about doing sth?的doing sth做主语吗? 分析英语语法结构We need to know what others are doing.书上说what others are doing是从句作宾语,我觉得宾语应该是to know啊?what others are doing是不是宾语补足语?那need是什么成分？ need to do 还是need doing ...我的车需要修理是my car need repairing 还是my car need to be repaired? 人做主语时,是spend to do sth还是spend doing sth是人做主语时,花掉某样物品. while doing 是一种省略主语+be的用法 那有没有when doing这种省略?请问 need doing 是需要被做有被动的意思这个词组里面的NEED是实意动词还是情态动词?
