Question

问几道sat语法问题，请大家帮忙！！！！！！！！！！！！！！

1. <A class of fresh faced, eager kindergartners arriving each Sept by school bus> to begin learning in the public school system.
C. when each Sept a class of fresh faced, eager kindergartners arrives by school bus
D. Each Sept a class of fresh faced, eager kindergartners arrives by school bus
答案是D，但是我觉得是C。 D中感觉有两个句子了啊，C为什么不对？
2. By running an additional performance, the drama club members raised a <profit larger in ticket sales than if they added the profits from bake sales, car wahses, raffles, and donations.>
C. larger profit from ticket sales than the total profits from bake sales, car washes, raffles, and donations
我觉得原文就可以了啊，有平行嘛，为什么一定要选C？
3. At the annual dessert festival, <carefully crafted> pastries <are presented> in elegant displays, drawing people from near and far to take part in <this> <yearly event>
答案说没错， annual和yearly不算重复？
4. The only student <to be awarded> a community service medal, the senior class president <has accumulated> more hours of service <than any> other student when he helped build homes<in> Guatemala last summer.
答案说是B，要怎么改？ C好像没有平行的感觉，错了吧
5. A person who uses hand tools <to accomplish> only <such tasks as> hanging pictures and fixing window shades <need not> purchase the <most cutting-edge> power tools developed for professionals.
答案说是没错，但是我觉得C应该用needs
6. Janet sent Howard to Richard's camp <for the summer>, <neber dreaming> that three weeks <would go by> before <hearing from> Howard,
答案说D错了，怎么改？为什么？

有点多，O(∩_∩)O谢谢大家

Answer 1

第一题C中用when句子成分不完整，只有包含when的从句，没了主句。D中只有一个简单的句子结构，楼主为什么说有两句话？
第二题比较对象是profit，所以larger要放在profit之前，而不是后面，且主句冗长，什么if they add都可以不要
第三题只有出现如annual yearly event这样的情况才是重复，他那个只不过的单词的替换而已，如果把后一个改成annually这个句子也是对的
第四题少连接词，应该是who/that has accumulated，应该是个定语从句
第五题need做情态动词，不用更改
第六题中hearing的主语变成three weeks了，所以不对，要加上Janet然后把hearing改成heard

Answer 2

1.D中是一个句子，逗号前后是并列的修饰成分。D比C简洁。
2 比较的时候要比同类相哦，profit 和if they added the profits 动词名词比不了。 larger profit 和total profits 才能比嘛
