Sarah and Janet have been friends ever since they (start) school. They do everything together: study, read, watch TV, surf the Internet, play sports and listen to music. Anyone has a problem can ask the other help. When Sarah was in the third grade, some of the other students made fun of her she was shy. Janet told the other students to stop (make) fun of Sarah, and she helped Sarah overcome her shyness. In the (five) grade, Janet had (difficult) in doing her maths exercises. She studied hard, she just couldn't understand the homework. Sarah helped Janet with her homework and (patient) explained every exercise to Janet. After six months, Jane did much better and even got "A" in the maths exam.
