今天是第二次考了。第一次710，因为头一天晚上大儿子拉肚子，只睡了3个小时，觉得没发挥好，不甘心国一个月又考了一次，多了30分，很满意了，不再考了。感谢老公支持，带了一晚上孩子，让我考前睡了一个好觉。 我想要说的是年轻的学弟学妹们要有信心，跟你们比起来我不年轻了，而且已经是两个儿子的妈了，还在考，还要上班。大家好好努力。 AI：麻烦哪位找找题号，我没找着。 The best teachers should expect students to challenge popular ideas...

During the past few years, however, our revenues have declined; meanwhile, the Allegro Musical Instrument Company introduced a line of inexpensive digital pianos and then saw its revenues increase. In order to increase Largo’s sales and in fact outsell Allegro, we should introduce a line of digital pianos in a variety of price ranges. Our digital pianos would be likely to find instant acceptance with customers, since they would be associated with the prestigious Largo name.” Math： 1。DS 说一个商店在last 13 天中每天卖书的中位数，第一个：last 7 day每天卖43本，第二个条件好像是告诉13天一共卖了144本，记不清了。 2。有一个等边直角三角形，从直角顶点出发，画一条垂直于底边的垂线，问那条垂线与其中一个直角边的夹角是多少？
