When reading a text, whether it's in English or not, it's a good idea to put yourself in the writer's shoes. On the other hand, it is good for writers to write with the reader's feelings in mind.
The easiest way to get a feel for the writer is to identify the words in the sentence that you think are the most important. Or identify some key words or phrases.

英語に限らず、文章を読むときに、その書き手の気持ちになって読むとよい。
逆に、書き手は、読み手の気持ちになって書くとよい。

書き手の気持ちになる一番簡単なのは、その文の中で、一番大事だと思う単語を特定(identify)する方法です。あるいは、鍵となるいくつかの語または熟語を特定します。
