2012年广东高考英语题,语法填空网上参考答案2疑问,
Mary will never forget the first time she saw him.He suddenly appeared in class one day,16 (wear) sun glasses.He walked in as if he 17 (buy) the school.And the word quickly got around that he was from New York City.
For some reason he sat beside Mary.Mary felt 18 (please),because there were many empty seats in the room.But she quickly realized that it wasn’t her,it was probably the fact that she sat in 19 last row.
20 he thought he could escape attention by sitting at the back,he was wrong.It might have made it a little 21 (hard) for everybody because it meant they had to turn around,but that didn’t stop the kids in the class.Of course whenever they turned to look at him,they had to look at Mary,22 made her feel like a star.
“Do you need those glasses for medical reasons?” the teacher asked.The new boy shook his head.“Then I’d appreciate it if you didn’t wear them in the class.I like to look at your eyes when I’m speaking to you.” The new boy looked at the teacher 23 a few seconds and all the other students wondered 24 the boy would do.Then he took 25 off,gave a big smile and said,“That’s cool.”
请问17题,填had bought 还是 would buy?24填 what,还是whether/if?

2012年广东高考英语题,语法填空网上参考答案2疑问,Mary will never forget the first time she saw him.He suddenly appeared in class one day,16 (wear) sun glasses.He walked in as if he 17 (buy) the school.And the word quickly got around
17：had bought
as if后面的句子当表示非事实时,应用虚拟语气,因为他不是来买这个学校的,所以用虚拟,根据原则：主句有现在时间（跟现在相反）,as if后面的句子用一般过去时;主句有将来时间用would+动词原形；主句有过去时间,用过去完成时.因为有walked表示过去时间,所以应该用过去完成时虚拟.主句没有将来时间,所以不用would buy.
24:what
all the other students wondered ___24___ the boy would do.是宾语从句,宾语从句中缺少这个男孩将做“什么事情”的含义,而且及物动词do后面缺少从句宾语,而表示“什么事情”的引导词,只有what ,what代指sth.
如果句子加多一个从句宾语it,如下：
all the other students wondered ___24___ the boy would do it.
此时用whether和if都可以,表示其它学生想知道是否这个男孩会按照老师说的取下大阳镜.
