All of my hard work paid off. My mom had spent a lot on my attending a private high school, so I made sure to push myself: I volunteered, took part in various clubs, and graduated with honors. I was so excited to start a new part of my life.Soon enough, the big day came, but it wasn't like what I had thought. The first two weeks were the most difficult days of my entire life. Every night I would cry myself to sleep. I was missing my family, my home and everything in my hometown so much and I didn’t know how to deal with my broken heart.To distract myself, I threw myself into my studies. I also found a ton of jobs. In any free time, I started forcing myself to go to the gym. I wanted to keep every part of my day busy so I wouldn’t think about how lonely I felt. Soon after, I began to control my eating, considering it another solution to my homesickness. But soon there was something wrong with me.Finally, I went to see a doctor. When the doctor told me I had no choice but to take time away from school, I started to fear. How could I stop? School was what I was best at. “I’m not so bad,” I thought in my head. But the result was that I was taken to hospital again a month later and my mother camewoefully. I had to take a semester off from school, and go to the treatment center near my home.If there are girls who are suffering similarly, I hope you know that there is hope and that you should have a positive attitude towards life. Though you may feel alone, there are so many people who can understand your struggle. That’s why I want to share my story.4. Why did the author push herself during high school?A.

Not only is the American rock group his favorite band, it was also his first ever concert.Taylor's mother, Nikki Hooper, says that she and her husband have always been huge fans of the Foo Fighters. In addition to traveling far and wide to see their shows, they even named their son after the drummer, Taylor Hawkins. So when the band played in their home city, they decided it was finally time for their son to see their beloved rock and rockers in concert.“He's been listening to them since he was born — mainly because his dad and I are super fans.” Mrs Hooper told BBC. “We called the event organizers and they said it would be no problem, but that we should know it would be a loud music event, so we gotTaylorsome special headphones. When we got there everyone was so welcoming to him.”Throughout the show, the audience continuously madeTaylorand his parents move closer to the stage. Furthermore, Mrs. Hooper helped her son stand out from the crowd by making him a sign that said he was a 5-year-old attending his first concert.When Foo Fighters front man Dave Grohl finally saw the sign and read it aloud into the microphone, the crowd began chanting for them to bring the youngster onto the stage. That's exactly what he did. When the stage managers brought the boy to the stage, Grohl asked Taylor to show the crowd how to dance.The small boy then danced to the whole song, making him an “Inter net wonder”.Taylordidn't just walk away from the show with memories, either;the band also invited him backstage to give him a number of gifts, includinga pair of Taylor Hawkins's drumsticks.8.

The family had John Smothers, his wife and their five-year-old daughter.One night after supper the little girl was ill with a serious stomachache, and John Smothers hurried downtown to get some medicine. He never came back. The mother was very sad over her husband's disappearance, and it was nearly three months before she married again, and moved to San Antonio. The little girl recovered and in time grew up to womanhood. After a few years had rolled around, the little girl also married in time, and she also had a little girl of five years. She still lived in the same house where theydweltwhen her father had left and never returned.By an unbelievable coincidence her little girl was taken with the same stomachache on the same night of the disappearance of John Smothers, who would now have been her grandfather if he had been alive. “I will godowntown and get some medicine for her,” said John Smith(for it was he whom she had married). “No, no, dear John,” cried his wife. “You, too, might disappear forever, and then forget to come back.” So John Smith did not go, and together they sat by the bedside of little Pansy. After a little while Pansy seemed to grow worse, and John Smith again wanted to go for medicine, but his wife would not let him.Just then, the door suddenly opened and an old man with long white hair entered the room. “Hello, here is grandpa,” said Pansy. She had recognized him before any of the others. The old man drew a bottle of medicine from his pocket and gave Pansy a spoonful. She got well immediately. “I was a little late,” said John Smothers, “as I waited for a street car.”12. What happened after John Smothers disappeared?A. His daughter took some medicine.B.

请你参与并完成小题。
出师表(节选)诸葛亮臣本布衣,躬耕于南阳,苟全性命于乱世,不求闻达于诸侯。
先帝不以臣卑鄙,猥自枉屈,三顾臣于草庐之中,咨臣以当世之事,由是感激,遂许先帝以驱驰。
后值倾覆,受任于败军之际,奉命于危难之间,尔来二十有一年矣。
先帝知臣谨慎,故临崩寄臣以大事也。
受命以来,夙夜忧叹,恐托付不效,以伤先帝之明,故五月渡泸,深入不毛。
今南方已定,兵甲已足,当奖率三军,北定中原,庶竭驽钝,攘除奸凶,兴复汉室,还于旧都。
此臣所以报先帝而忠陛下之职分也。
送东阳马生序(节选)宋濂当余之从师也,负箧曳屣行深山巨谷中。
穷冬烈风,大雪深数尺,足肤皲裂而不知。
至舍,四支僵劲不能动,媵人持汤沃灌,以衾拥覆,久而乃和。
寓逆旅,主人日再食,无鲜肥滋味之享。
同舍生皆被绮绣,戴朱缨宝饰之帽,腰白玉之环,左佩刀,右备容臭,烨然若神人;余则缊袍敝衣处其间,略无慕艳意,以中有足乐者,不知口体之奉不若人也。
盖余之勤且艰若此。
