　　55. Many house builders offer rent-to-buy programs that enable a family with insufficient savings for a conventional down payment to be able to move into new housing and to apply part of the rent to a purchase later.

　　(A) programs that enable a family with insufficient savings for a conventional down payment to be able to move into new housing and to apply

　　(B) programs that enable a family with insufficient savings for a conventional down payment to move into new housing and to apply

　　(C) programs; that enables a family with insufficient savings for a conventional down payment to move into new housing, to apply

　　(D) programs, which enables a family with insufficient savings for a conventional down payment to move into new housing, applying

　　(E) programs, which enable a family with insufficient savings for a conventional down payment to be able to move into new housing, applying

　　答案解析如下：

　　(A)programs that enable a family with insufficient savings for a conventional down payment to be able to move into new housing and to apply

　　【错误】 简洁明了：“enable……to be able to……”存在语义重复。

　　(B)programs that enable a family with insufficient savings for a conventional down payment to move into new housing and to apply

　　【正确】 “enable”与其逻辑主语“programs”正确地保持了主谓一致。“to move……”和“to apply……”正确地用“and”平行在一起，叙述了“enable”的具体内容。

　　【大意】 许多住房建筑商提供了rent-to-buy项目，该项目使一个无力支付传统购房定金的家庭先入住新房并将部分租金分配到之后的购买价格中。

　　(C)programs; that enables a family with insufficient savings for a conventional down payment to move into new housing, to apply

　　【错误】 代词指代：“that”之前有“;”，且“programs”和“enables”主谓不一致，因此“that enables……”无法继续做“programs”的定语从句。那么“that”就是一个单纯的代词，GMAT所考察的标准书面英语中，代词this、that、these、those如果单独使用(“those students”、“that of……”这样的结构就属于不单独使用)，其指代不明，因为书面语不能用手去指这指那。

　　(D)programs, which enables a family with insufficient savings for a conventional down payment to move into new housing, applying

　　【错误】 主谓一致：“enables”的逻辑主语是“programs”，主谓不一致。

　　(E)programs, which enable a family with insufficient savings for a conventional down payment to be able to move into new housing, applying

　　【错误】 简洁明了：见(A)。

　　【最优解题思路推荐】

　　(D)定语从句的动词与其逻辑主语主谓不一致，立即排除。

　　(C)中代词“that”单独使用指代不明，排除。

　　“enable……to be able to”语义重复，排除(A)和(E)。因此选择(B)。
