即∠NBF=∠MBN 又∵BN=BN ，BM=BF ∴△BNM ≌△BNF ∴MN=NF 又∵NF=NC+CF ∴MN=AM+CN⑵ 图3猜想MN=CN —AM27.（2012黑龙江鸡西，27，10分）为了迎接“五·一”小长假的购物高峰，某运动品牌服装专卖店准备购进甲、乙两种服装，甲种服装每件进价180元，售价320元；乙种服装每件进价150元，售价280元. ⑴若该专卖店同时购进甲、乙两种服装共200件，恰好用去32400元，求购进甲、乙两种服装各多少件？ ⑵该专卖店为使甲、乙两种服装共200件的总利润（利润=售价—进价）不少于26700元，且不超过26800元，则该专卖店有几种进货方案？ ⑶在⑵的条件下，专卖店准备在5月1日当天对甲种服装进行优惠促销活动，决定对甲种服装优惠每件a （0＜a ＜20）元出售，乙种服装价格不变，那么该专卖店要获得最大利润应如何进货？【答案】解：⑴设购进甲种服装x 件，则购进乙种服装（200—x ）件. 根据题意得：180x+150（200—x ）=32400 解得：x=80 ∴设购进甲种服装80件，则购进乙种服装120件.⑵设购进甲种服装y 件，则购进乙种服装（200—y ）件. 根据题意得：26700≤（320—180）y+（280—150）（200—y ）≤26800BACDM NF 2 3 1BACDMN图1图2BACD MNB A CDMN图3解得：70≤y≤80 ∵y 是正整数 ∴共有11种方案.⑶设总利润为W 万元.W=（140—a ）y+130（200—y ）=（10—a ）y+26000 ①当0＜a ＜10时，10—a ＞0，W 随y 增大而增大. ∴当y=80时，W 有最大值，此时购进甲种服装80件，乙种甲种服装120件. ②当a=10时，⑵中所有方案获利相同，所以按哪种方案进货都可以. ③当10＜a ＜20时，10—a ＜0，W 随y 增大而减小. ∴当y=70时，W 有最大值，此时购进甲种服装70件，乙种甲种服装130件.28.（2012黑龙江鸡西，28，10分）如图，在平面直角坐标系中，已知Rt △AOB 的两条直角边OA 、OB

But the houses are changing all the time.( )61. What will the house of the future look like? Could it have gardens on its walls, or a pool with fish for dinner? Architects (建筑学家) believe that they may come true one day.The only thing for sure is the houses will be as green as possible in the future.( )62. Many architects in the world would like to build a house like a leaf, the surface of the house collects sunlight during the day. The energy can be used to heat water, produceelectricity, and even make fresh air for the room. The“root”(根) of the house is deepunder the ground. It uses the soil to control the room‟s temperature.( )63. Like a lizard (蜥蜴), changing color with the weather is the most important design of a lizard house. When it‟s in the bright sun, the cover of the house will turn white toprotect it from strong heat. During dark days, it turns dark and takes in as much lightand heat as possible to produce energy.( )64. This design is perhaps for the future of food. It has a garden on the outside wall of the house. People can plant tomatoes, carrots and green tea on them. So every morning,you just need to walk outside and collect your meals.( )65. Looking to the future isn‟t the only way to be green. Sometimes, the old ways of building houses can also help cut down energy use. For example, a chimney (烟囱) canbe a useful air conditioner because it is easier for hot air to run out of the chimney.答案：61—65 DECBA( B )【2012黑龙江鸡西】People enjoy traveling around the world during their holidays.
