二分球：8个
三分球：4个
罚球：6个
设：2分球个数为x,3分球个数为y,罚球个数为z
列方程式：2x+3y+z=34(1)
x+y+z=18(2)
x=2y(3)
解（1）,（2）,（3）个三元一次方程.

解 设麦蒂投三分球x个,则投两分球2x个 罚球y个
x+2x+y=18①
3x+2×2x+y=34②
②-①,得：
4x=16
x=4
把x=4代入①,得：
12+y=18
y=6
三分：4个 两分：4×2=8个 罚球6×1=6分
答：他投入4个三分8个两分,罚球得6分

解题思路：根据圆周角定理可知，∠PBQ=∠PCQ，因为∠PCQ是三角形PCA的外角，所以∠PCQ＞∠PAQ．

应传球给乙．
理由：如图，设AQ与圆相交于点C，连接PC
因为∠PBQ=∠PCQ＞∠PAQ，
即乙射门的角度更大．
所以仅从射门角度考虑，应将球传给乙，由乙射门好．

点评：
本题考点： 圆周角定理．

考点点评： 本题考查了圆周角定理，同圆或等圆中，同弧或等弧所对的圆周角相等，都等于这条弧所对圆心角的一半，并且圆外角＜圆周角＜圆内角．

EFF是指出场效率：
介绍一下公式:
出场效率＝{(得分+篮板+助攻+抢断+盖帽)-[(投篮数-命中数)+(罚球数-罚球命中数)+失误]}/出场次数

可以翻成"他还会干什么呢?"/"还有呢?"/"然后呢?"之类的.你的第一个理解是对的.
You can even do this!what else can't you do?
You can't even do this!what can you do?
