It was on a warm autumn day that my father and I walk into my new high school. After registered in the classroom, I was taken to my dormitory by the volunteer. Altogether I had five roommates, two of which arrived later. I got to know my new roommate immediately. Although I was quite unwilling to say “Goodbye” to my father, but he had to leave to my hometown in the evening. I suddenly realized I had grown up and that I had to look after me and live independently. Not until then I know my senior high school life had real begun.

【解析】试题分析：作者介绍自己的父亲陪他一起去报名上高中的事情。
1.考查时态。纵观全文可以看到本文是描述过去的事情的，故用过去时态，walk改成walked。
2.考查动名词。After是介词，后接动词要用动名词形式，故用registering。
3.考查冠词。此处是泛指某间教室，不是特指，故用the。
4.考查连词。此处为定语从句，先行词是roommates，室友，是人，关系代词用whom，做宾语。
5.考查名词单复数。此处我的新室友有好几个人，故用复数。
6.考查连词。Although和but不能同时使用，只能用一个，Although位于句首，不能去，故去掉but。
7.考查介词。此处是固定短语：leave for：意为去哪里，这里指回家，故用for。
8.考查代词。此处意为我得照顾我自己，需用反身代词myself。
9.考查倒装句。Not until 位于句首需对主句部分倒装，部分倒装需借助于助动词，根据时态和谓语动词，可以确定助动词是did，放在I的前面。
10.考查副词。此处为副词修饰动词，用really。
