第一题 would 是情态动词 情态动词后面要接动词原形
你可以还原成陈述句 或许好理解些
you would knock before coming in ,please.coming 或许对你有迷惑作用 但是come之所以用ing是因为介词before
第二题 只有D是非谓语动词 ,非谓语才能作主语 the last man to leave the house作主语 由于不是主语从句 所以没有需要用到谓语成分
B项是现在进行时的被动 但在这里语境好像不合适 因为消防队 头头 是自己出来的 如果是抬出来的 可能用B恰当些 因为现在进行时的被动语态表示此时此刻某事正在被做
比如 The sports meeting is being held in our school.
They are said to have finished doing their task这个对,因为表示据说他们已经完成任务
to 表示动词不定时符号时 它后面肯定接动词原形 故不能接finished ,这里have是助动词 有表完成的意思
据说 有几种句型可以相互转换 it's said…… etc.
people said……
They are said……
希望可以帮到 如有不懂 烦请继续追问
关于楼上的回答，我把第二题再跟你说细点，首先这很明显是要选个定语，谓语是was，A项不符合，B项时态不对，即使这样用意思也不对，C项现在分词的完成式一般是不作定语的
