= = 中国初三就是美国高一,美国初中两年,高中四年
美国高一的科学课是学生物的,没有物理题化学题.
高一数学也是分两批的,学习不好的学一元一次方程 y=mx+b.学习好的学几何,从点线面学起.
我现在上高中最后一年,前几年的学习资料都扔了,如果你问我高三数学题我或许还能给你找一些,抱歉.
我在我的SAT复习书上给你找到2个题.
（1）if 2x+3=9,what is the value of 4x-3.这个不用翻译吧.答案9
（2）Edna and Nancy leave the house of a common friend at the same time and walk for 4 hours.Edna walks due east at the average rate of 4 kilometers per hour and Nancy walks due north at the average rate of 3 kilometers per hour.What is the straight-line distance between them,in kilometers,at the end of the 4 hours?翻译：Edna往东走,4千米每小时,Nancy往北走,3千米每小时,问4小时后,他们相距多远.用勾股定理画三角算,答案是20.
去看SAT的题好啦
基本就是美国初中内容为主的
Edna and Nancy leave the house of a common friend at the same time and walk for 4 hours. Edna walks due east at the average rate of 4 kilometers per hour and Nancy walks due north at the average rate of 3 kilometers per hour. What is the straight-line distance between them, in kilometers, at the end of the 4 hours?
