There ________ many changes to Beijing over the past years.| A．are | B．have | C．has been | D．have been |
|
答案
| D |
解析
试题分析：There be句型表示“某地(或某时)存在有某人(或某物)，而并非某地(某人、某物或某时)拥有什么东西”，句中有若干个名词作主语，动词be常与后面主语中的第一个名词在数上一致。have一般表示某人有某物。句意：在过去几年中，北京发生了许多变化。结合语境可知本句描述的是现在已经完成的动作，本句主语many changes表达复数含义，故选D。
点评：There be句型表示“某地(或某时)存在有某人(或某物)，而并非某地(某人、某物或某时)拥有什么东西”，其实质是倒装句。其也有时态变化，要借助于不同的助动词。但是当助动词是be动词时，一般可以省略，只用一个be动词就行。 |
