One afternoon, while I was doing my homework, then suddenly I heard someone knocking at the door. I rose my head, looking out of the window to see who it was. A man of about 50 broad shoulders and glasses were standing on the door steps. He was tall, wearing in an old army coat. He grew a wild beard. A big black hat was pulling forward over his eyes so that it was hard to see her face clearly. His shoes were old but worn out. It was a big hole in one of his socks. He had with him a black box in one hand. Only after I took a few more closer looks at him I recognize that he was my neighbor ten years ago.then 去掉

(答案→)then 去掉 解析：文章介绍作者在做作业的时候，发现有人敲门，结果看见一个陌生的男子，仔细的看了他几眼才认出这是他10年前的邻居。【小题1】当我在作业的时候，我听到有人敲门。While引导的时间状语从句，后面是主句，then 去掉【小题2】我抬起头，看看是谁。Rise是不及物动词， raise是及物动词，raise one’s head抬起头【小题3】一个50来岁的有着宽阔肩膀戴眼镜的男子站在门口。50之后加with，用with介词短语做定语。【小题4】主语是A man of about 50 broad shoulders and glasses中心词是a man谓语用单数： were ---- was 【小题5】他很高戴着一个军帽。Wear是及物动词，in去掉【小题6】一个大的黑色的帽子被向前拉遮住了眼睛。A hat和pull是被动关系，用pulled【小题7】因为这是一个男的，用形容词性物主代词his【小题8】.他的鞋子很旧也破了。这两个形容词是并列关系：but----and【小题9】袜子上有一个大洞。用There be句型：It ---- There 【小题10】只有在我更仔细的看了他几眼我才认出这是我10年前的邻居。Only+时间状语从句，后面的主句用部分倒装：I前加did

你的回答很对
