Question

几道SAT语法问题

1. (To those of us) who had heard the principal of the high school talk about the budget , the news of the staff cuts was not surprising.
从语感上，我知道括号里是对的，可是直接to us不是更简洁吗？加those是为什么？

2. It was obvious that all of the candidates had planned A.( carefully ) for the televised debate, B.( for each ) C.( answer to ) the opening question showed evidence D.( of having been ) rehearsed.
答案是no error D括号是什么语法？这里的having been是不是主语错误，接在evidence后面，有点混乱。。

3. (As a place that is home to 131 species of fish，the Cahaba River is flowing) for 190 miles through the heart of Alabama.
正确答案 Home to 12 species of fish, the Cahaba River flows 这里的home是作动词吗，那不需要改成Homing吗？

4. In winter, when the ponds froze over, the villagers went skating, (and the most venturesome of whom played chase and executed complicated turns on the ice).
正确答案 with the most venturesome playing chase and executing
这里是什么语法？with直接引出后半句？

详细点！谢谢！
home作名词，那这里是同位语吗？

Answer 1

第一个绝对不能改成 to us。因为后面who引导的定语从句修饰的是those而不是us。比如你可以说to those who had heard...,但是不能说to us who had heard...除非你这是非限定性定语从句，who前面要加逗号才行。
第二个是没错误的，B后面的for是因为，然后showed的主语是each（后省略了candidate), 如果你觉得evidence后面主语混乱，可以理解成the candidates showed evidence of their having been rehearsed这样也没错。至于时态，因为是已完成的 当然是完成时。
第三个home不是动词，可以理解为形容词，作为。。。的家的。homing显然不对。
第四个显然不能用and 因为后半句根本就不是完整的一句话。and只能连接并列的句子和短语成分（包括单词），总之后面不是完整的句子是不能用and的。并不能理解成是with引出的后半句。如果将句子倒一下语序，改成 In winter, when the ponds froze over, with the most venturesome of whom played chase and executed complicated turns on the ice, the villagers went skating.可能好理解一点。with后面只是个定语

Answer 2

1纯属语感，个人喜好，不是语法问题
2plan of doing sth,另，been rehearsed肯定不对，不用过去是表被动吧
3不是动词，唯一的名词，不用加冠词
4with用法相当于汉语里，一群人去滑冰，“其中”有特别勇敢的。。。明白？

Answer 3

1）who had heard ...是those的定语从句，而非修饰us，试分析一下语意上的区别；

2）show evidence of sth. / doing sth. / having done sth. 本题从时间先后的角度分析；

3）此处home为名词，home的动词语意与“家”无关，home为形容词时后面必须加名词（定语形容词）；

4）with引导的伴随状语，也有人认为是独立主格。

Answer 4

1楼和3楼解释都很对

唯独希望2楼确实看懂了再发表意见

showed evidence 是指each candidates have been rehearsed answering every opening question.

语法丢很久了，但我不认为其中有什么问题。
