- 试题详情及答案解析
- The number of people who can afford to buy their own houses ________ more than 80%, but a number of houses _________.
| A．are; hasn’t been built | B．are; has built |
| C．is; haven’t been built | D．is; have built |
- 答案：C
- 试题分析：考查动词时态、语态和主谓一致。“负担得起买他们自己房子的人的数量超过了百分之八十，但是大量的房子已经被建成。”The number of +复数名词作主语后面的谓语动词用复数形式，故第一空填is; a number of +复数名词作主语后面的谓语动词用单数，根据句意，第二空表示已经完成且主语和谓语动词之间是被动关系，故第二空填haven’t been built,所以选C
考点：考查动词时态、语态和主谓一致。
