但写上总不会错，这是肯定的，就是写的时候要规范。
我是大连地区的，我们要求可以不写单位，只在最终结果后注明单位就可以。
最直接的方法，问你们的物理老师，他最清楚你们地区的要求。
分析：
（1）由AB是⊙O的直径，AB⊥DA，可得AD是⊙O的切线，又由DC是⊙O切线，根据切线长定理即可求得答案；
（2）连接BF、CE、AC，由切线长定理求出DC=DA=4，求出DO=5，CM、AM的长，由勾股定理求出BC长，根据△BGC∽△FGE求出CG/GF=BC/EF=3/5，则CG=3/8CF；利用勾股定理求出CF的长，则CG的长度可求得．
解答：
（1）证明：
∵AB是⊙O的直径，AB⊥DA，
∴AD是⊙O的切线，
∵DC是⊙O切线，
∴DA=DC．
（2）解：连接BF、CE、AC， />由切线长定理得：DC=DA=4，DO⊥AC， ∴DO平分AC，在Rt△DAO中，AO=3，AD=4，由勾股定理得：DO=5， ∵由三角形面积公式得：1/2DA•AO=1/2DO•AM， 则AM=12/5，同理CM=AM=12/5， AC=24/5． ∵AB是直径， ∴∠ACB=90°， 由勾股定理得：BC=√[6^2-(24/5)^2]=18/5． ∵∠GCB=∠GEF，∠GFE=∠GBC，（圆周角定理） ∴△BGC∽△FGE， ∴CG/EG=BC/EF=18/(5/6)=3/5 在Rt△OMC中，CM=12/5，OC=3，由勾股定理得：OM=9/5， 在Rt△EMC中，CM=12/5，ME=OE-OM=3-9/5=6/5，由勾股定理得：CE=(6/5)√5， 在Rt△CEF中，EF=6，CE=6/5√5，由勾股定理得：CF=(12/5)√5． ∵CF=CG+GF，CG/EG=3/5， ∴CG=3/8CF=3/8×[(12/5)√5]=(9/10)√5]． 各省市中考英语选择题集锦 （一） 长沙市二、语法选择(共15小题，计15分)从A、B、C、D4个选项中选择正确答案填空。 26.
