Code:

String [] data = loadStrings("data.txt");
for(int i = 0; i < data.length; i ++){
  if((int)((float)i / 2) == i / 2){
    println(data[i]);
  }
}

To read the second word of a line, first split the line into an array of words, and then access the second element in the array.  The first example in the split reference should help: http://processing.org/reference/split_.html

st33d's reply prints every even-numbered line (counting from 0) in your file.  An easier way to check for this is to use the modulo operator, %, like so:

Code:

  if (i%2 == 0) {
    // i is an even number
  }
