Question

【题目】The number of children who have lost parents to AIDS ___ to rise to over 26 million in 2017.

A. are expected B. is expecting

C. are expecting D. expected

Answer 1

【答案】D

【解析】

试题分析：句意：到2017年，那些因艾滋病而失去父母的孩子数量预期会增加到送二千六百万。其中who引导定语从句修饰children。整个句子的主语The number of children，作主语时，谓语动词用单数形式。主语与动词expect之间是被动关系，故选D。
