/sually contains one or two Chinese characters. Chinese people often name a baby with their best wishes in mind, like wishes for good health, bright future and happiness. Some names imply the birth time, birth place, weather or even a natural phenomenon at the time of the baby's birth. In terms of choosing the characters, parents still need to consider how they sound when combined into a name. They definitely wouldn't want their child to be teased or given a bad nickname because of the pronunciation.
Yours, Li Hua

[sup]4[/sup] Then we did it on our own, and he walked around to help us. With the help of the craftsman, our hard work paid off.[sup]5[/sup] We could make dough figurines finally. At last we took photos with the craftsman. How happy we all were! 范文二: A Day with a Craftsman Last Friday we experienced a nice day with a craftsman, who was invited to teach us how to make a piece of dough.[sup]1[/sup] This Friday we will move on to a new unit, and I'm writing to inform you of some details. When the craftsman entered the classroom, we students all applauded to welcome him. Two boys helped him with the tools.Hardly had he sat down at a table when he began to show us the basic skills of making dough figurines.[sup]2[/sup] We all paid special attention to what he was doing behind him.[sup]3[/sup] Then we began to do it -by ourselves while the craftsman walked around and made necessary explanation for us.[sup]4[/sup] At last we learned to make dough figurines and took photos with him.

When the craftsman came into the classroom, we gave him a warm welcome and two hoys helped him with the tool box. First, he showed us the basic steps and skills of making dough figurines. We stood around him and watched him attentively. Then we started to have a try ourselves. The old man walked around and helped us patiently. Finally, put the figurines we made on the table and took pictures with the old craftsman. Seeing the figurines we made by ourselves, we were all very excited. We hope we can have more activities of this kind in the future!

BBC C(II )证明:连结 A 1B,设 A 1 B AB 1=E,连结DE.由已知得,四边形 A 1ABB 1为正方形,则 E 为 A 1B 的中点 .因为D是BC 的中点,因此 DE ∥A 1C.又因为 DE 平面 AB 1D,A1C 平面 AB 1D,因此 A 1C∥平面 AB 1D.(III )由( II )可知 A1 C∥平面 AB 1D ,因此 A 1与 C 到平面 AB 1D 的距离相等,因此.由题设及 AB=AA 1=2,得 BB 1=2,且.因此= ×,因此三棱锥A1 -AB 1D 的体积为.19.已知椭圆 C:(b>0)的一个焦点坐标为(2,0).(I )求椭圆 C的方程;( II )已知点E( 3, 0),过点(1, 0)的直线l (与x 轴不重合)与椭圆C交于M, N两点,直线ME与直线x=5 订交于点F,试证明:直线FN与x 轴平行 .【答案】(I)=1;( II )证明看法析.【分析】试题剖析:(Ⅰ)由题意可知因此,即可获得求椭圆的方程;(Ⅱ)①当直线的斜率不存在时,易证直线与轴平行②当直线的斜率存在时,设直线的方程为.因为点,因此直线的方程为.令,因此.由消去得. 明显恒成立 .因此这时可证,即.因此直线轴 .试题分析:(Ⅰ)由题意可知因此. 因此椭圆的方程为.(Ⅱ)①当直线的斜率不存在时,此时轴. 设,直线与轴订交于点,易得点是点和点的中点,又因为,因此,因此直线轴.②当直线的斜率存在时,设直线的方程为.因为点,因此直线的方程为.令,因此.由消去得.明显恒成立.因此因为,因此.因此直线轴 .综上所述,因此直线轴 .20.已知函数 f ( x)=xcos+a , a∈R.(I )求曲线 y=f ( x)在点 x= 处的切线的斜率;( II )判断方程 f '(x)=0( f '(x)为f(x)的导数)在区间(0,1)内的根的个数,说明原因;( III)若函数F( x) =xsinx+cosx+ax在区间(0,1)内有且只有一个极值点,求 a 的取值范围 .【答案】( I ) .

The"Doorman"On a trip to California, my family stopped for lunch. As we walked toward the entrance to the restaurant, a man, with a 16 beard and dirty hair, jumped up from a bench and opened the door for us. Regardless of his 17 , he greeted us in a friendly way.Once inside, my daughters whispered, "Mom, he 18 ." After we ordered our lunch, I explained, telling the kids to look 19 the dirt. We then watched other customers approach the restaurant but many 20 him. Seeing this rudeness truly upset me. The day I became a mother, I had resolved to set a good 21 for my children. Yet sometimes when things didn't go right, being a good example was 22 . When our meal arrived, I realized I had left the car-sick pills in the truck. With the windiest trip ahead, the kids needed them, so I 23 myself from the meal and went for them.Just then, the "doorman" was opening the door for a couple. They rushed past him without even acknowledging his 24 Letting them in first, I said a loud "thank you" to him as I 25 .When I returned, we talked a bit. He said he was not allowed inside 26 hepurchased food. I went back and told my family his 27 . Then I asked our waitress to add one soup and sandwich. The kids looked 28 as we had already eaten, but when I said the order was for the "doorman", they smiled. When it was time to 29 our trip, I noticed the "doorman" enjoying his meal. Upon seeing me, he stood up and thanked me heartily. He then 30 his hand for a handshake and I gratefully accepted.I suddenly noticed his tears in eyes-tears of 31 .What happened next drew great astonishment: I gave the doorman a 32 ! He pulled away, with tears 33 down his face.Back in truck, I fell into deep thought. While we can't choose many things in life, we can choose when to show gratitude. I said thanks to a man who had 34 held open a door for me, and also said thanks for that 35 to teach my children by example.16. A. heavy B. long C. messy D. grey17.
