    When I was at middle school, I have a nice classmate, that was the first foreigner I had ever met. She was friendly and very pretty. She was good in three languages, although he was born in China. It was interested that her father was a Frenchman while her mother came from England. All of them were teaching at a university at that time. She was crazy collecting stamps, listening to pop music, as well as playing the football. Her dream was to be an engineer, so she usually studied harder to achieve it. She often told funny stories in English to make us laughing. We all liked her.

    Every time you visit Disney World,there's something new to see. What began in 1971 as the Magic Kingdom now includes the high­tech,movie­mad Disney and Animal Kingdom. Each time the park expands,so do your chances to spend money. How can you save?As a family guide to Disney World,I've been to the park more than 25 times with my kids,and I've developed a few money­saving plans.

    {#blank#}1{#/blank#}Even if you're visiting for fewer days,it's a deal(the pass costs$229 for visitors ages 10 and up,$183 for kids ages three to nine and is free for kids under age three).Without the pass,you'll have to pay separately for Pleasure Island and the water parks. A single trip to Blizzard Beach,for example,would cost a family of four $100.

    {#blank#}2{#/blank#}The prices at some of the nicer restaurants,especially those in Epcot's World Showcase,are much lower at noontime than at dinner. It's wise to make reservations before you leave home. Call 407­W­DISNEY.

    {#blank#}3{#/blank#}F or $65,you can get a Magic Kingdom Club Gold Card(call 1­800­56­DISNEY).Card­holders get up to 20 percent off Disney hotel rooms,plus price breaks on character breakfasts,theme park tickets and goods from Disney stores.

    {#blank#}4{#/blank#}Character­theme dinner shows are expensive,costing a family of four about $140,and even a character breakfast,where Mickey or Donald Duck joins you for cakes,can set you back $50.If your budget is tight,try to meet the characters inside the theme parks and at free in­park shows. You can watch the Diamond Horseshoe show,for example,in the Magic Kingdom for no additional cost,while the similarly themed Hoop­Dee­Doo Musical Revue requires expensive tickets.

    {#blank#}5{#/blank#}By then,the kids will really know what they want,and you won't waste money on expensive things.

六•一儿童节,小文到公园游玩.看到公园的一段人行弯道MN(不计宽度),如图,它与两面互相垂直的围墙OP、OQ之间有一块空地MPOQN(MP⊥OP,NQ⊥OQ),他发现弯道MN上任一点到两边围墙的垂线段与围墙所围成的矩形的面积都相等,比如:A、B、C是弯道MN上的三点,矩形ADOG、矩形BEOH、矩形CFOI的面积相等.爱好数学的他建立了平面直角坐标系(如图),图中三块阴影部分的面积分别记为S1、S2、S3,并测得S2=6(单位:平方米).OG=GH=HI.
