try to use as much english as possibleusing native language is not illegal
not bad if he mixes both languages
videos with english subtitles
songs he likes in english language
also this type of people who say nothing in L2 are usually low confidence in speaking and they are selfish characters so each time he speaks english don �t immediately correct him... or at least in the beginning let him make mistakes and just correct 1-3 mistakes each time...
from my own experience these type of students suddenly one day they start talking as soon as they feel they have enough lexicon to use... they don �t like making mistakes or the worse being corrected.
So give him new words with examples to learn
It �s a difficult situation i can feel ya....
