Mr. Wu     (teach) us for two years and he’s already very popular. I think this is because he really enjoys      (teach) English. He loves it, in fact. He’s got so much energy, and this is one class you do not fall       (sleep) in! He talks loudly and      (fast), and waves his hands about a lot when he gets       (excite). He’s really amazing when he gives us lessons. I respect him a lot.
