- 试题详情及答案解析
- It wasn’t until he was diagnosed with cancer ______ he realized the significance of health.
| A．when | B．that | C．which | D．what |
- 答案：B
- 试题分析：考查强调句。句意：知道他被诊断出癌症，他在意识到健康的重要性。判断是否为强调句，把It wasn’t until和空去掉，看是否为完整的句子。去掉后发现本句为he was diagnosed with cancer，he realized the significance of health.为独立完整的句子，因此为强调句。故选B。
考点：考查强调句
