16．There's nothing like experiencing history to understand it．So instead of reading  about the U．S．Civil War in textbooks，some schoolchildren in Virginia are creating videos related to the conflict，in which the northern Union and southern Confederate states fought over several issues，including slavery，from l861-1865．
    In one scene，children act as two Union generals，meeting at the Kaploan Klver in central Virginia．The l2-and l3-year-olds are producing a mini-video on the key role temporary pontoon bridges（浮橋）played during the war．After building and crossing a  pontoon bridge，Union soldiers defeated a Confederate army in the Battle of the  Wilderness．
    In another scene，students act as soldiers who are marching to the river with guns．Today，the area is part of a national military park．Park Educational Coordinator Peter Maugle shows the children how to hold the fake guns．"Hopefully they will understand why these places are important through projects and programs like this，and they will make an effort to keep these places preserved for future generations，''he said．
    Another background is a plantation where much of the Battle of the Wilderness was fought．At this location，another group of children is focusing on the diary of a woman who lived in the region during the war．Student director John Ashley says the experience has made him think more about the human aspect of the war．Filmmaker Ghil Hong donated his time to help the students，who have understood it quickly．"They are trying to convey the emotions during the Civil War．They really focus on wanting the story to be accurate，''Hong added．
    With help from advisors，the children also research，write，and edit the videos．Alexis Albert got a chance to try out directing and learned a lot about Civil War history in the process．"It helps me more as a student understand it more than reading a book and looking at words，"he said．
    The project is sponsored by the Journey Through Hallowed Ground，which raises  awareness of historical sites from Pennsylvania to Virginia，including many Civil War battlegrounds．

14．閱讀下面的短文，然后按照要求寫一篇150詞左右的英語短文．
Education does Count（excerpt）-Bill Gates
Hundreds of students send me e-mail each year asking for advice about education．They want to know what to study，or whether it's OK to drop out of college since that's what I did．
My basic advice is simple and heartfelt．"Get the best education you can．Take advantage of high school and college．Learn how to learn．"
It's true that I dropped out of college to start Microsoft，but I was at Harvard for three years before dropping out-and I'd love to have the time to go back．As I've said before，nobody should drop out of college unless they believe they face the opportunity of a lifetime．And even then they should reconsider．
In my company's early years，we had a bright part-time programmer who threatened to drop out of high school to work full-time．We told him no．
Quite a few of out people didn't finish college，but we discourage dropping out．
Having a diploma certainly helps somebody who is looking to us for a job．
There's not a perfect correlation between attitudes in high school and success in later life，of course．But it's a real mistake not to take the opportunity to learn a huge range of subjects，to learn to work with people in high school，and to get the grades that will help you get into a good college．
【寫作內(nèi)容】
1．以約30個詞概括這段短文的內(nèi)容；
2．然后以約120個詞談談你對教育的看法，內(nèi)容包括：
   （1）為什么有些學生想中途放棄學業(yè)去創(chuàng)業(yè)；
（2）你認為讀書與事業(yè)之間的關(guān)系是怎樣的；
（3）你自己有何打算．
【寫作要求】
1．在作文中可以使用自己親身的經(jīng)歷或虛構(gòu)的故事，也可以參照閱讀材料的內(nèi)容但不得直接引用原文中的句子；
2．作文中不能出現(xiàn)真實姓名和學校名稱．
[評分標準]
概括準確，語言規(guī)范，內(nèi)容合適，篇章連貫．

15．In the latest romance-drama，Descendants of the Sun （《太陽的后裔》），a handsome soldier Yoo Shi-jin（柳時鎮(zhèn)） （Song Joong-ki）（宋仲基） meets the pretty doctor Kang Mo-yeon（姜暮煙） （Song Hye-kyo）（宋慧喬） in a hospital，and he doesn't hesitate to hit on her．
The dialogue，which takes place early in the first episode，immediately indicates that this is no ordinary South Korean drama．There's no family feud，or secret crush，or love tangles，or guesses and misunderstandings．The 16-episode show is set in the fictional war-torn country of Uruk（烏魯克）．Song Joong-ki is the leader of a special warfare command unit，while Song Hye-kyo plays a doctor who works for a humanitarian medical organization．Both are sent in the midst of disaster and disease as part of their work with UN peacekeeping troops．Both know and show clearly what they want and what they hate．
But what stands out the most are Song's skills as a pick-up artist（撩妹技能）．
Boldness and creativity are the key weapons in his arsenal．When Kang invites Yoo to drink wine with her，Yoo，who is not allowed to drink alcohol as a soldier，says，"There is a way"before kissing her．Forget about the"eighth-episode rule"．This kiss happens in the fourth．
Humor also does the trick．On their first date in a cinema，Yoo says，"This is the most exciting moment of my life．The moment I am with a beautiful woman before the theater lights go out．"When Kang tries to give Yoo a hard time，Yoo jokes，"I mistook you for a beautiful woman because it's dark．"
And actor Song Joong-ki，who just came back from two years of military service last May，makes sure he delivers his pick-up lines just right．
"In Deep Rooted Tree （《樹大根深》） and The Innocent Man （《善良的男人》），he[Song Joong-ki]showed he had the steel to play fearless and heartless men-that he could be taken seriously as an actor，despite his pretty face．In Descendants，he hits the emotional core of every scene，whether he has to be bold and amorous，guarded and mysterious，or sad，"said critic Foong Woei Wan in The Straits Times．

32．What is the relationship between Song Joong-ki and Song hye-hyo？B
A．lover           B．colleague           
C．a(chǎn)ctor           D．doctor-patient
33．Why say that the Descendants of the Sun is no ordinary South Korean drama？B
A．Because actors know and show clearly what they want and what they hate．
B．It broke the previous Korean old story．
C．It exits family feud and love tangles．
D．The pick-up artist is unique and special．
34．When the Descendants of the Sun tells us that heterosexual（異性） contacts is important to have some quality includingD．
①humor       ②Boldness and creativity    ③bold          ④emotional
A．①②B．①②③
C．②③④D．a(chǎn)bove all
35．What is the article mainly about？A
A．Introduce a drama called the Descendants of the sun．
B．Song Zhongji could be taken seriously as an actor，despite his pretty face．
C．The Descendants of the sun open a new pattern to pick-up woman．
D．The reason why the Descendants of the sun gain success．

4．Home to me means a sense of familiarity and nostalgia（懷舊）．It's fun to come home．It looks the same．It smells the same．You'll realize what's changed is you．Home is where we ran remember pain，live，and some other experiences； We parted here； My parents met here； I won three championships here．

I'm lucky because I know my first home still exists．It exists in my mind and heart，on a physical property（住宅） on West 64th street on the western edge of Los Angeles．It is proof I lived，I grew and I learned．
Sometimes when I feel lost，I lie down and shut my eyes，and I go home．I know it's where I'll find my family，my dogs，and my belongings．I purposely leave the window open at night because I know I'll be blamed by Mom．But I don't mind，because I want to hear her say my name，which reminds me I'm home．
43．Why does the author call her parents'bed her"safe zone"（Paragraph 3）？B
