164. The commission proposed that funding for the park's development, which could be open to the public early next year, is obtained through a local bond issue.

1. that funding for the park's development, which could be open to the public early next year, is
   
2. that funding for development of the park, which could be open to the public early next year, be

3. funding for the development of the park, perhaps open to the public early next year, to be

4. funds for the park's development, perhaps open to the public early next year, be

5. development funding for the park, which could be open to the public early next year, is to be

Choice B is best. Choice A attaches the relative clause which could be open ... to the noun development, when, in fact, it is the park that could be open. Choice C omits that, the object of proposed that is needed to introduce the clause describing the proposal. C also uses to be unidiomatically where be is correct: the commission proposed [that] funding ... to be obtained is wrong. Choice D incorrectly uses perhaps open to the public ... to modify development; the phrase should modify park. Choice E, which seriously distorts meaning, says that the commission proposed development funding and that such funding could be open to the public ....

此题为什么要选择B呢？尤其不理解为什么最后用be？

我的分析思路：

which could be open to the public early next year肯定是修饰the park，所以AD排除，C用perhaps open to the public early next year不对，排除，E中的 is to be在意思上跟主语 the commission不匹配，所以选择B。也可以得到正确答案。

但是B的最后那个地方使用的是be，我不理解

是虚拟的问题,楼主可以把要虚拟的单词真理一下.在这里我提醒楼主注意suggest这里单词,有2个意思,建议/暗示,前者要虚拟,后者不要,做题注意对意思的理解.
