马老师:您好!我遇到一个难题,请您赐教。我儿子上小学二年级。平时考试,他总是有些马虎,难题几乎没错过,可是那些简单的小问题,却经常会多少出点错。因此,他的考试成绩总是得不了满分。我和老师想尽办法也不奏效。您说到底是他脑力不够,还是有什么毛病?请您帮我们走出困境,让孩子考出好成绩。我代表全家表示衷心的感谢!陕西西安温郁华 Mr. Ma: Hello! I encountered a problem, please enlighten me. My son is in second grade. Usually exam, he is always a bit sloppy, the problem is almost never missed, but those simple little problems, but often how many mistakes. Therefore, his test scores can not always get the perfect score. My teacher and I tried my best not to work. In the final analysis, he is not mentally challenged or is there anything wrong with him? Please help us to get out of the woods so that the child can test his grades. I’d like to express my heartfelt thanks on behalf of the whole family!
