The conditions under which I can do my best active reading

First, I need a quiet environment. This is the most important. I feel it really hard for me to read or study in noisy surroundings,particularly when I read a foreign article. I cannot concentrate my energies when some one is talking loudly around me.

Second, I can understand better if I clear up my mind before reading. I will miss some points if I am considering other things when I read. If I still cannot concentrate on my reading, I will read it out loud.

Third, I always like to underline some key words or take some notes in margins. This helps to remember what I am reading. 

Finally, rereading is helpful to get more information and understanding. At this moment, I also find underlining and notes are useful. And I will use dictionary at the second or third time reading to remove the gaps. Sometimes I do not understand somewhere at first, but after second reading I will get it.
