问：老师，这里面Iamafraidtosleep.如何理解？是否很难入睡的意思？

问：老师这里面的not可以翻译成“而不是”吗，这里not作什么成分，表转折吗？另外setin如何理解？
1. I am afraid to sleep. I have been afraid to sleep for the last few weeks. I am so tired that, finally, I do sleep, but only for a few minutes. It is not a bad dream that wakes me; it is the reality I took with me into sleep. I try to think of something else. Immediately the woman in the marketplace comes into my mind.
比较以下两个表达：
be afraid to sleep：害怕睡觉；不敢睡。比如：睡觉做噩梦。
be afraid of sleeping：担忧睡着。比如：第二天一大早需要出差办事，赶火车等。
2. The eighteenth century, for example, produced from various sources a tendency to fix the language into patterns not always set in and grew.
not always set in and grew 是过去分词短语作定语，修饰 patterns。划线部分的意思是：把语言固定在不一直固定而是在进步的模式中。
