定语从句,状语从句it is needful to keep in mind the conditions of ill

将复合句拆分为两个简单句方便你理
it is needful to keep in mind the conditions of ill-health.
he worked almost continually under the conditions of ill-health.
这里状语almost continually的位置不限
【改成二号位状语】it is needful to keep in mind the conditions of ill-health under which he almost continually worked.
【改成三号位状语】it is needful to keep in mind the conditions of ill-health under which he worked almost continually.
这样表达也都是正确的,仅仅是状语在一号位、二号位和三号位的位置变换,不引发歧义.
再问： almost continually的位置不限 状语可以随便放吗？为什么这么放呢？谢谢您的回答，我采纳啦！！
再答： 你好，状语在句中的位置基本可互相转换，目的仅是平衡句子结构，也就是说你之前提问中的情况是不限定的，没有特殊的原因规定要放在一号位，写作翻译时也是一样，可灵活插入状语，不必拘泥于一种形式。O(∩_∩)O
