2.     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

答案选c

我选的e,因为我觉得后面的rental rates是解释前面如何can no longer afford to buy homes的

不太理解c后面的那个yet转折该如何理解?

谢谢!

根据全题目的意思~~~these families can no longer qualify to buy homes是用来描述middle-income families ,他们之间并不是并列关系,用for比较恰当.

还有rising rental rates不是解释前面如何can no longer afford to buy homes...yet有And despite this; nevertheless的意思

所以~~答案是c~~

leaving them with no equity or tax write-offs to offset the expenditures

是伴随状语，指之前已经迫使他们花多余25％的钱来支付房钱，从而使得他们无力抵消日常的花销

for these families是指中产阶级，因此for表原因没什么问题

yet做的是转折
