140.    As the housing affordability gap widens, middle-income families are especially hard-hit, and these families can no longer qualify to buy homes, and rising rental rates force them to use far more than the standard 25 percent of their incomes for housing, leaving them with no equity or tax write-offs to offset the expenditures.
(A) and these families can no longer qualify to buy homes, and
(B) since these families can no longer afford to buy homes, furthermore
(C) for these families can no longer afford to buy homes, yet
(D) and these families can no longer afford to buy homes; however,
(E) and these families can no longer afford to buy homes, for
C，我选的是B，我觉得有递进的意思，但为什么这里用的是转折？还有since在这里表原因用法有错误吗


？

furthermore错，不能做连词。yet一方面....另一方面

C说是转折的意思，但我还是觉得递进的意思比较贴切，说middle-income hard hit, 因为他们买不起房子，而且，rent rate还怎么样，递进的关系很明显呀

jnlvo兄说furthermore不可以做连词，可能是一个解释，但我不太明白，那如果我在这里要表递进，该怎么说呢？

我在金山词霸上看到这一句，这里的furthermore作什么用？

Furthermore, these child-raising families may raise other people's children in addition to their own.

谢谢！

在金山词霸中的Furthermore作为副词可修饰整个句子,但在B选项中需要的是个连词,故不能用Furthermore.

大全上说since 表因果关系不是最好,我不太理解.

有那位大侠能给我解释一下because,since,for,as该四者表因果关系连词的各自用法吗!!!!!

以下皆是记忆之事，尽供参考～

for 指的是非直接原因，而且因果效果比较弱；

because直接原因，as，since ＋句子；

我看到了总结再回贴吧～
