例如：
As you are already 18 years old, you should know what to do and what not to do. (你已經(jīng)18歲了，應(yīng)該知道什么該干什么不該干。)
這個(gè)句子用because連接就不太合適。好在軍隊(duì)職稱(chēng)考試中并不要求作這種分辨。
…for 注意：一般只能放在主句后面，即主句 + for從句，例如：
He must have gone to bed, for it is too late. (他肯定已經(jīng)睡了;現(xiàn)在已經(jīng)很晚了。)—— 該句不能用because
now that / seeing that / considering that (由于…)
Seeing that this problem was settled, they proceeded to the next one.(鑒于這個(gè)問(wèn)題已經(jīng)解決，他們開(kāi)始進(jìn)行下一個(gè)問(wèn)題。)
…in that(在于…)一般放在主句后面，例如：
Humans are superior to animals in that they can use languages as a tool to communicate. (人比動(dòng)物高等，因?yàn)槿四芤哉Z(yǔ)言作為工具進(jìn)行交際。)
