I was eighteen years old, fresh out of high school with a bright future to look forward to, when I received the "big" news that I got cancer. This was a big deal for some one of my age to stand. What should I do? Lost in self pity or fight for myself? I chose the second.

After four months of treatments. I overcame my difficulties and started to be a new person--- someone who took nothing for granted and who learned to appreciate everything and everyone around me. Years passed and I received my certificate (证书) in medical assisting, met a wonderful man, moved to New York and got married. Truly, life couldn't have been any better.

For years, I had always kept in touch with St.Jude Children’s Hospital in Memphis, TN and the children living with cancer who were being treated there. What a truly beautiful place!

No patient was ever turned away regardless of ability to pay. As my 20-year anniversary(纪念日) of being a cancer survivor approached, I wanted to do something special. I organized a fund raiser. calling it“A Mission of Love." and Thanks to my generous family and friends, raised $4,000 for St.Jude’s. Three quarters of the money would be given as a donation(捐献)to the hospital, and what was left would go toward buying toys for the children. I also had organized a T-shirt painting activity for the hospital.

My husband and I flew to Memphis with 50 T-shirts and a huge bag of cloth

paint the day before Thanksgiving. We went to the toy store and filled three shopping carts with all kinds of toys. It was as though we were celebrities when the employees and other shoppers knew what we were doing.

On Thanksgiving Day we pulled into the front gate of St.Jude. After dropping the toys off, we went to a waiting area where some children were waiting anxiously to begin painting. They picked out their shirts and my husband and I helped them get started. To see them smile was one of the greatest gifts I could have ever received. When the activity was over, we dropped off the donation to a kind worker, and our visit came to an end.

Dorothy Lee and her husband were driving home from a study group one night when their car suddenly hit something. Mrs.Lee looked at her husband, who was driving, and saw his head move down and up several times and fall. In the next minutes Mrs Lee managed to avoid a serious accident while stopping the car, called 911 on her cellphone and tried to make her husband come back to life before an ambulance arrived. But at the hospital, soon after learning her husband had died of sudden heart trouble. Dorothy's heart appeared to give out as well. She experienced sudden sharp pains in her chest (胸腔), lost senses and knew nothing.

Doctor's of that hospital were surprised at finding: There wasn't any evidence of heart trouble. Finally. doctors thought that Mrs.Lee had suffered from a broken-heart syndrome (伤心综合症). The disease looks like heart trouble, but appears to have little connection with heart trouble. It is caused mainly by stress and other strong feelings. The disease is uncommon, making up for about 1% to 2% of people ---and about 6% of women----- who are likely to suffer such sudden heart trouble. It can be very dangerous sometimes, but for the most part patients recover quickly, with no lasting damage to their hearts.

If patients are hospitalized with the broken-heart syndrome, their hearts might be beating as little as 20% 0f what it should work. But within 48 t0 72 hours, many recover to the 60% level that is considered healthy. It is uncommon.

Mrs.Lee's heart was so weakened by her husband's death that she nearly died. The 63-year-old woman needed a special balloon pump(球囊泵) during the first days in the hospital. But in spite of warnings by her doctors, she attended her husband's funeral (葬礼) five days later.

The Olympic Stadium for the London Games is in Stratford in the northeast of London. The stadium will host the opening and closing ceremonies, as well as athletics events.

Designers say the Olympic Stadium will be the most sustainable ever built ---in fact, the motto of the stadium is "reduce, reuse, recycle". They have tried to avoid using too much steel, for example, as the metal is in short supply at the moment. They managed to use 75 percent less than other stadiums. The top part of the stadium was built from old gas pipes. The Olympic Stadium will be able to seat 80,000 spectators.

There are other stadiums, including an Aquatics(水上的)Centre for watersports---and, of course, the Olympic Park. The Olympic Park covers 2.5 square kilometers of land in east London. This land used to be a polluted industrial site, but now is covered in greenery. Around 2,000 trees have been planted so far. Lakes have been built and 300,000 wetland plants put in place, making it the largest ever river planting that have taken place in a UK city. Visitors can enjoy the surroundings from one of the bars or cafes onsite, or get involved with the markets and other events.

Stratford is known as a poor area of London, and organizers hope the bid will create many jobs for local people.

辽宁省大连市大连八中高三期中考试作文:人生不只有考题,还有诗和远方

人生不只有考题,还有诗和远方 作文题 阅读下面的材料,根据要求写作。 上海16岁女生武亦姝成为《中国诗词大会》比赛第二季冠军,很多粉丝惊呼这位00后少女,“满足了对古代才女的所有幻想”。在实际的学习中,武亦姝不但能背诵两千首古诗词,而且文理均衡。成功登顶后,她淡定地表达:“比赛结果都无所谓,只要我还喜欢诗词,只要我还能享受到它带给我的生活中的快乐,就够了。” 高考语文试卷,古诗文默写只占6分。不少学生甚至家长一直以来存在这样的质疑:为了只占几分的古诗文默写,值得让学生花那么多时间学习和背诵吗? 对此你有什么看法?写一篇文章表达你的看法。 要求:围绕材料内容及含意,选好角度,确定立意,明确文体,自拟标题;不要套作,不得抄袭,不少于800字。 命题说明: 本题来自辽宁省大连市大连八中高三期中考试。 命题方向 人文底蕴:人文积淀、审美情趣 科学精神:理性思维、批判质疑、勇于探究 学会学习:乐学善学、勤于反思 实践创新:问题解决 审题 限制性 1.真实情境的限制。作文要求考生表达自己的看法,考生在谈看法时一定要紧抓任务、围绕材料。材料主体是武亦姝夺冠事件,体现出她对古诗词的热爱和深厚的人文积淀。而在这样的背景下,却有一部分学生甚至家长因为高考古诗文默写分值低而对古诗文学习存在质疑:“为了只占几分的古诗文默写,值得让学生花那么多时间学习和背诵吗?”这是家长的质疑。“比赛结果都无所谓,只要我还喜欢诗词,只要我还能享受到它带给我的生活中的快乐,就够了。”这是武亦姝学习古诗词的初衷,即来源于内心真正的热爱。“武亦姝不但能背诵两千首古诗词,而且文理均衡”,这是命题人的暗示。考生要据此表达自己的看法,回应这部分人的质疑,不得脱离写作的真实情境。 2.典型任务的限制。材料的核心任务是回答学生甚至家长的质疑:“为了只占几分的古诗文默写,值得让学生花那么多时间学习和背诵吗?”考生的写作对象是心存质疑的学生和家长,要体现对象意识和交流意识,体现对这一质疑的思考。行文中在回应质疑时应联系武亦姝夺冠事件,分析花费时间学习和背诵古诗词到底值不值得,要围绕材料内容及含意表达看法。“写一篇文章表达你的看法”,限定文体为议论文。 3.价值判断的限制。认真审读材料,我们便能读出命题者鲜明的价值判断。不少学生甚至家长对学习背诵古诗词存在质疑,他们是站在应试、功利的角度来看待这一问题的,即看问题的角度很褊狭。命题人对武亦姝的案例陈述中隐含了一个价值判断:“武亦姝不但能背诵两千首古诗词,而且文理均衡。”这说明古诗词的学习不但不影响其他学科的发展,还能给我们的生活带来快乐,那么何乐而不为呢?这就需要考生在写作时能充分表达自己的看法,去除这部分人的功利心理。

辽宁大连市第八中学下册机械能守恒定律单元测试卷 (word版,含解析)

一、第八章机械能守恒定律易错题培优(难) 1.一足够长的水平传送带上放置质量为m=2kg小物块(物块与传送带之间动摩擦因数为 0.2 μ=),现让传送带从静止开始以恒定的加速度a=4m/s2开始运动,当其速度达到 v=12m/s后,立即以相同大小的加速度做匀减速运动,经过一段时间后,传送带和小物块均静止不动。下列说法正确的是() A.小物块0 到4s内做匀加速直线运动,后做匀减速直线运动直至静止 B.小物块0到3s内做匀加速直线运动,之后做匀减速直线运动直至静止 C.物块在传送带上留下划痕长度为12m D.整个过程中小物块和传送带间因摩擦产生的热量为80J 【答案】ACD 【解析】 【分析】 【详解】 物块和传送带的运动过程如图所示。 AB.由于物块的加速度 a1=μg=2m/s2 小于传送带的加速度a2=4 m/s2,所以前面阶段两者相对滑动,时间1 2 v t a ==3s,此时物块的速度v1=6 m/s,传送带的速度v2=12 m/s 物块的位移 x1= 1 2 a1t12=9m 传送带的位移 x2= 1 2 a2t12=18m 两者相对位移为 121 x x x ?=-=9m 此后传送带减速,但物块仍加速,B错误; 当物块与传送带共速时,由匀变速直线运动规律得 12- a2t2=6+ a1t2

解得t 2 =1s 因此物块匀加速所用的时间为 t 1+ t 2=4s 两者相对位移为2x ?= 3m ,所以A 正确。 C .物块开始减速的速度为 v 3=6+ a 1t 2=8 m/s 物块减速至静止所用时间为 3 31 v t a = =4s 传送带减速至静止所用时间为 3 42 v t a = =2s 该过程物块的位移为 x 3= 1 2 a 1t 32=16m 传送带的位移为 x 2= 1 2 a 2t 42=8m 两者相对位移为 3x ?=8m 回滑不会增加划痕长度,所以划痕长为 12x x x ?=?+?=9m+3m=12m C 正确; D .全程相对路程为 L =123x x x ?+?+?=9m+3m+8m=20m Q =μmgL =80J D 正确; 故选ACD 。 2.如图,滑块a 、b 的质量均为m ,a 套在固定竖直杆上,与光滑水平地面相距,b 放在地面上.a 、b 通过铰链用刚性轻杆连接,由静止开始运动,不计摩擦,a 、b 可视为质点,重力加速度大小为,则 A .a 减少的重力势能等于b 增加的动能

B .根据F 大于8N 的图线知,F =6N 时,a =0m/s 2,由 1mg a F M M μ= - 可知: 13100611 μ??=?- 解得 μ=0.2

由图示图象可知,当F =10N 时,滑块与木板相对滑动, B 的加速度为 2110.2310104m/s 11 B mg a a F M M μ??== -=?-= 故B 正确,不符合题意; D .当F =10N 时,A 、B 相对滑动,木块A 的加速度 22m/s A Mg a g M μμ= == 故D 正确,不符合题意. 故选C . 【点睛】 本题考查牛顿第二定律与图象的综合,知道滑块和木板在不同拉力作用下的运动规律是解决本题的关键,掌握处理图象问题的一般方法,通常通过图线的斜率和截距入手分析. 2.传送带广泛的应用于物品的传输、分拣、分装等工作中,某煤炭企业利用如图所示的三角形传送带进行不同品质煤的分拣,传送带以6m/s 的速度逆时针匀速转动,两边的传送带长都是1m ,且与水平方向的夹角均为37?。现有两方形煤块A 、B (可视为质点)从传送带顶端静止释放,煤块与传送带间的动摩擦因数均为0.5,下列说法正确的是( ) A .煤块A 、 B 在传送带上的划痕长度不相同 B .煤块A 、B 受到的摩擦力方向都与其运动方向相反 C .煤块A 比煤块B 后到达传送带底端 D .煤块A 运动至传送带底端时速度大小为2m/s 【答案】A 【解析】 【分析】 【详解】 B .煤块A 开始受到的摩擦力方向沿传送带方向向下,与运动方向相同,煤块B 下滑过程中受到的摩擦力方向沿传送带方向向上,与运动方向相反,选项B 错误; CD .对煤块A 根据牛顿第二定律可得 1cos37sin37mg mg ma μ?+?= 解得 2110m/s a = 煤块A 达到与传送带共速的时间 0116 s 0.6s 10 v t a = == 位移
