4. ______________(据报道，这个地方卫生组织25年前就成立了)when Dr. Mark became its first president.

5. The patients’ heath failed to _______________________ (严重恶化需要精心护理.).

答案与解析：

1. his wife was kept in the dark

本题考查固定搭配，词组in the dark 可以表达的意思有“蒙在鼓里，在暗处，秘密的”，符合题意.

2. Unless you sign a contract with the insurance company for your goods

本题考查对连词unless用法的掌握。unless表示"除非......否则"，相当于"if...not"，常用于引导条件状语从句。

3. the power of the medium is exaggerated

本题考查宾语，exaggerate为动词，意思为“夸大”，符合文章.

4.It is reported that the local health organization was established 25 years ago/The local health organization is reported to have been established 25 years ago

本题考查形式主语it及被动语态的用法。It is reported that...意为"据报道......"，it为形式主语，后面的that从句为句子的真正主语，表示"卫生组织成立"应该用被动语态。另外，本句也可以直接用报道的对象the local health organization充当主语，原来从句中的谓语动词转换成相应的不定式的完成式。

5. such an extent that he was put into intensive care

本题考查程度句型such…that…的用法，such an extent that意思是“这样一个程度，以至于…”.
