I found a list of most frequently used English words they are not in contexts but I believe they will be useful. many of them will be new for me. and I should learn them. they will be stored in my memory like if they been written with a pencil. they could be removed. when I study them for the next time, they will stuck faster. and each time I study them.. they will be more stable on my memory and I will not forget them easily.. I will be able to recognize a lot of them in contexts I guess.. unless I learned a different meaning of the word than what it shown on the particular context :|
