　　语篇解读：每个人都想健康、快乐，但疾病或事故难免发生，因此懂得一些家庭护理知识就尤为重要了。

　　1．A.Sometimes　　　　　　 B．Unfortunately

　　C．Actually D．Naturally

　　解析：选B　sometimes"有时"；unfortunately"不幸地"；actually"事实上"；naturally"自然地"。上文说"人人都想健康快乐"，然后笔锋一转，"________，疾病或事故可能会没有预兆地降临"，上下文有明显的句意转折，只有unfortunately可以表达出这层意义。

　　2．A.reason B．notice

　　C．warning D．signal

　　解析：选C　reason表示"原因"；notice表示"通知"；warning表示"警报"；signal表示"信号"。without warning意为"没有预兆；没有警报"，"疾病或事故可能会没有预兆地降临"，与上文中的"人人都想健康快乐"相呼应。

　　3．A.weak B．patient

　　C．ill D．healthy

　　解析：选C　weak表示"虚弱的"；patient表示"耐心的"；ill表示"生病的"；healthy表示"健康的"。因前面提到"疾病"，后面又提到cared for，由此可以推知C项正确。

　　4．A.wait for B．look for

　　C．look after D．look at

解析：选C　wait for"等待"；look for"寻找"；look after"照顾"；look at"看......"。生病的人应是得到家人的照顾，即选择"look after"。
