求大神帮忙解决一道英语阅读题
After an absence of thirty years,I decided to visit my old school again.I had expected to find changes,but not a completely different building.As I walked up the school drive,I wondered for a moment if I had come to the right address.The dirty red brick houses had been swept away.In its place stood a bright,modern block.A huge expanse of glass extended (延展) across the face of the building,and in front,there was a well-kept lawn (草坪) where previously there had been “an untidy gravel (沙石) yard”.

答案

42.B.从第二句话得出.我期待学校能有一些改变,但我没料到会看到一栋完全不同的建筑.说明了学校变化大,很难辨认了.
43.A 错就错在completely上.
44.C.首先排除D,这个人是他们的校长,所以肯定不是一个淘气的孩子.A选项也可以排除,因为此题问的是must be肯定是,校长不一定就是他的老师.排除B选项是因为old这个词,校长是严肃的,文章中也说过新校长是年轻人,但这并不代表之前的校长就年迈啊.选C是因为文中说到Mr.ghastly had iron discipline(铁的纪律)所以说他是一个严厉的校长.
45.D 作者通篇都在赞扬新学校,所以态度是积极的.AB是消极的,所以不选.不选C是因为题中说作者很开心学校还是原来的样子很明显是错的,因为学校完全变了.
