答：本题考词汇,考句子理解和翻译.
作为一个高中老师,说实话,throw a party是第一次见到,猜测是举办了一个聚会,但为什么要用throw一词,不解.in welcome of sb.in celebration of 也没见过,需要查词典.
前两个是常见的介词短语,A表示“为了.的荣誉”,“向.表达敬意”,B.表示“支持”,容易排除.
CD很有可能没有这样的介词短语,要么是in the welcome of .在欢迎.in the celebration of ...在庆祝.结构不对,意思也不通.所以很有可能是A.
在做题时,不能查词典,只好这样先做了.
没有查到in welcome of sb.的用法.好不容易在两本词典上找到了in welcome的短语用法：
wel·come3 / `welkəm / noun ★★《7in 1》
1.[count or uncount] an act of welcoming or greeting someone:
in welcome:He held his hand out in welcome.
《21世纪》：
in welcome
(以表) 欢迎
又一处：
welcome
1.noun an instance or manner of greeting someone
•you will receive a warm welcome
| [mass noun] he went to meet them with his hand stretched out in welcome
可惜一直没有找到in welcome of sb.的例句.但并不能表示就不能这么用.
搜索网络,发现有这样的用法：
Kaohsiung Sister City Association hosts a dinner in welcome of...
Kaohsiung Sister City Association hosts a dinner in welcome of Deputy Mayor Chi-Yu Chen.Post Date:2011/6/18.Kaohsiung Sister City Association hosts a ...
APEC Foundation hosts a lunch in welcome of Deputy Mayor Chi-Yu Chen ...Kaohsiung Sister City Association hosts a dinner in welcome of...
这样看来,这一题很难判断那一题能得分了.如果是传统固板的考官出的题,为A.如果是新潮的考官出的,则为C.
我认为本题设计有误.楼主责疑有理.
