sat的几个语法问题?
1 one of the playwright's hopes was that the play would shock theatergoers; instead,it suceeded only in confusing them.为什么这里用would呢?
2 sb was an artist (( who serves)) apprenticeships before going on to a successful career.括号部分为什么错了?
3 my dog won more awards at obedience trials than my brother's dog.这里的答案是狗和狗作比较,但是我怎么觉得是狗做这件事进行比较呢(另一个答案than my brother's dog wins)请问我的想法哪里错了?

1 是时态问题.was 和would 相对一致.如果是is的话,would就变成will了-----is 和will相对一致:one of the playwright's hopes IS that the play WILL shock -- -. 2 如果括号里面是 who serves as / who served as...哦哦,2确实应该是serve as,不过后面有before结构前面到底是用完成时一般现在 还是 一般过去时? 3 若选项为than my brother's dog won对吗?1 before going on to a successful career强调的是一种现象,与“时间”没有关联。2-- --than my brother's dog won中的won应该由did这个助动词替换。又如:She doesn't walk as quickly as he does (does代替walks)She didn't walk as quickly as he did (did代替walked)
