"Now, Alice," said her friend Mrs. Jackson, "is he such a terrible student?" "That's just the 3 ," the other woman replied. "Tom is my best student. The problem is that he's now so lazy that he never gets his 4 done. He hasn't handed me 5 of his homework for three weeks and I'd be surprised 6 he did now." 7 before had Mrs. Jackson seen Miss Smith look so unhappy. "Have you 8 with him about it?" she asked.
