阅读下列短文，从每题所给的四个选项(A、B、C和D)中，选出最佳选项。
A
With hospitals and nursing homes tending to thousands of patients every year accidents can and do happen. These incidents whether they are through carelessness or otherwise, can leave patients feeling powerless. That?s not the case.
“There is grow ing public awareness. People are feeling they have more rights and they have tools in hand to make a complaint,” said Ralph Montano, spokesman for the California Department of Public Health, which regulates hospitals and long-term care facilities in the state.
That department received more than 6000 complaints about hospitals in 2007; in the most recent year statistics are available. The complaints can be about mixed-up lab results, medicine errors, foreign objects left in a patient during surgery or a host of other topic.
Similarly, the California department of Aging received 43,000 nursing home complaints in 2014. Some said patient abuse or neglect of patients; others reported missing items. And some commented on the quality of the food.
But finding the channels through them to put forward a complaint can be tiring and time consumption. Many consumers simply don?t bother, and some become lost in the system. Whether the complaint is against a hospital or a long-term care facility, the process is similar—and many people can help, including the facility?s staff, insurance company representatives and state regulators.
If you want to make a complaint while in the hospital, Patti Harvey, vice president of quality and patient care services for Kaiser Permanente in Southern California, recommends talking with the bedside nurse. If that doesn?t work, you can talk with other people higher in the chain of command, up to the hospital administrator. If the problem isn?t still taken care of—say you disagree with your treatment plan or have a problem with your doctor—member service offices at each hospital can help address your concerns.
1. Why are there more complaints from patients?
A. Because there are more departments to deal with complaints.
B. Because in the hospital there are more accidents than before.
C. Because it?s convenient for people to put forward complaints.
D. Because hospitals have more and more rights.
2. Many consumers don?t make a complaint because __________.
A. complaints are bad for a long-term care facility
B. few accidents happen
C. many complaints are lost
D. it takes time to make a complaint
3. The last paragraph mainly tells us _________.
A. to solve problems with the hospital quickly
B. something about Patti Harvey
C. how to make complaints in the hospital
D. we should say we disagree with the treatment plan
4. Who can help if you complain against a hospital or a long-term care facility?
A. Jack—a representative of an insurance company.
B. Peter—a medical officer from the government.
C. Rudy—a headmaster of a medical university.
D. Tom—a teacher of a medical school.
B

When other nine-year-old kids were playing games, she was working at a petrol station. When other teens were studying or going out, she struggled to find a place to sleep on the street. But she overcame these terrible setbacks to win a highly competitive scholarship and gain entry to Harvard University. And her amazing story has inspired a movie, “Homeless to Harvard: The Liz Murray Story” shown in late April.
Liz Murray, a 22-year-old American girl, has been writing a real-life story of willpower and determination. Liz grew up in the shadow of two drug-addicted parents. There was never enough food or warm clothes in the house. Liz was the only member of the family who had a job. Her mother had AIDS and died when Liz was just 15 years old. The effect of that LOSS became a turning point in her life. Connecting the environment in which she had grown up with how her mother had died, she decided to do something about it.
Liz went back to school. She threw herself into her studies, never telling her teachers that she was homeless. At night, she lived on the streets. “What drove me to live on had something to do with understanding, by understanding that there was a whole other way of being. I had only experienced a small part of the society,” she wrote i n her book Breaking Night.
She admitted that she used envy to drive herself on. She used the benefits that come easily to others, such as a safe living environment, to encourage herself that “next to nothing could hold me down”. She finished high schoo l in just two years and won a full scholarship to study at Harvard University, but Liz decided to leave her top university a couple of months earlier this year in order to take care of her father, who has also developed AIDS. “I love my parents so much. Th ey are drug addicts. But I never forget that they love me all the time.”
Liz wants moviegoers to come away with the idea that changing your life is “as simple as
making a decision”.
9. The main idea of the passage is __________.
A. what a hard time Liz had in her childhood
B. how Liz managed to enter Harvard University
C. how Liz struggled to change her life
D. why Liz loved her parents so much
10. What actually made her go towards her goal?
A. Willpower and determination.
B. Envy and encouragement.
C. Decisions and understanding.
D. Love and respect for her parents.
11. When she wrote “What drove me to live on… I had only experienced a small part of the society”, she meant that _________.
A. she needed to travel more around the world
B. she would do something for her own life
C. she could hardly understand the society
D. she had little experience of social life
D
Philadelphia, Pennsylvania is America?s fifth largest city. Once a major American colonial city, it is the home of America?s first library, its first hospital, and its first zoo. Now it is also the first US city to be named a World Heritage City. On November 6, 2015, Philadelphia joined more than 260 other cities that have been recognized for their influence on the world. These cities include Paris, France, Florence, Italy, and Cairo, Egypt.
“Today marks the start of a new and exciting chapter in the history of Philadelphia,” remarked Philadelphia Mayor Michael Nutter when the announcement was made. “As a World Heritage City, Philadelphia is being officially recognized on the global stage for its wealth of contributions to the world.
To be named a World Heritage City, a city must be home to a UNESCO World Heritage site. UNESCO World Heritage sites are selected for their universal value and significance. For Philadelphia, the site is Independence Hall.
Independence Hall is where two of the most important documents in US history—the Declaration of Independence and the US Constitution—were adopted. The Declaration of Independence, approved on July 4, 1776, united the 13 former British colonies and declared them independent from British rule. The US Constitution, signed in 1787, established the American democratic system of government. A democracy is a system of government in which the people elect their leaders. The Constitution later spelled out the basic freedoms American citizens have.
Philadelphia Deputy Mayor Alan Greenberger says the city?s selection as a World Heritage City also reflects its educational, cultural, and economic achievements. The city is home to dozens of colleges and universities, and many museums, such as the Philadelphia Museum of Art. “Philadelphia has rightfully earned its place as one of the greatest cities in the world.”
Greenberger says.
12. We can learn from Paragraph 1 that Philadelphia ________.
A. is known for many America?s firsts
B. has been famous as a World Heritage City
C. has the best American hospital
D. has contributed a lot to the global economy
13. In Paragraph 2, Michael Nutter is talking about _________.
A. the World Heritage City
B. the significance of the city?s selection
C. the history of Philadelphia
D. the contributions of the city
14. What opinion does Alan Greenberger hold?
A. It?s easy for the city to win the honor.
B. The honor will bring the city a better future.
C. It won?t be long before the city takes off.
D. The city really deserves the honor.
15. What could be the best title for the text?
A. Philadelphia Makes a Difference
B. Philadelphia Develops a Lot
C. Philadelphia Makes History
D. Philadelphia Wins Global Respect
第二节（共5小题；每小题2分，满分10分）
根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。
Weighing the Options
Making decisions when shopping is often a tough call. Even if you?re satisfied with the first dress you try on, would you go on looking for alternatives, comparing styles and prices, until literally dropped dead?
Psychology researchers have studied how people make decisions and concluded there are two basic styles. “Maximizers” like to take their time and weigh a wide range of options—sometimes every possible one—before choosing. “Satisficers” would rather be fast than thorough.
16. __________ S o even if they see what would seem to meet their requirements, they can?t make a decision until after they?ve examined every option to make sure that they?re making the best possible choice. Researchers followed 548 job-seeking college seniors at 11 schools from October through their graduation in June. They found that the maximizers landed better jobs. 17. _________.
“The maximizer is kicking himself because he can?t examine every option and at some point had to just pick something,” they say. “Maximiz ers make good decisions and end up feeling bad about them. 18. _________
Satisficers also have high standards, but they are happier than maximizers. Maximizers tend to be more depressed and to report a lower satisfaction with life, their research found.
Faced with so many choices in our lives, we need to learn how not to waste time and energy on our decision-making.
19. ________ For instance, if you?re picking a restaurant for a lunch meeting, first deciding
on a certain part of town or type of cuisine can narrow your options.
Once you?ve arrived at a decision, stick with it. 20. __________ To limit the number of options you can set a time limit for decision-making. Say you are buying a new bag, you could spend an amount of time studying features, price and value—but if you give yourself only five minutes to make a decision, and there are only these bags you can consider, you?ll save time. You?ll be happier with your decision, too.
A. The other is to make decisions more accurately at the beginning.
B. Satisficers make good decisions and end up feeling good.
C. First of all, decrease your range of options.
D. Comparing is often a must when you make a decision.
E. Maximizers are people who want the best.
F. Just accept that no decision is ever completely perfect.
G. Their starting salaries were 20 percent higher but they felt worse about their jobs.

Hi Worried:
I?m sorry to know that you?re having such a bad time at the moment. The truth is everyone will have one of those periods when things seem to be wrong, so you don?t have to worry so much. The important thing is to learn to control your temper so that you may not do or say anything you?ll regret. Here are three useful tips:
First, talk to someone you trust about how you feel. This is a good way of letting your anger out without hurting others or yourself. Second, go outdoors and play team games with your friends，as physical exercise is an effective way to get rid of anger .And third, remain optimistic about your future. Such a positive attitude towards life can be helpful in lifting your spirits.
I hope you?ll soon feel calmer and carry on as normal.
Your
s,
Mike

高一物理期中考试总结发言稿整理 【】期中考试过后大家一定要给自己做个总结，了解自己的情况，以后才能加以改正。小编为大家整理了高一物理期中考试总结发言稿，希望大家喜欢。 期中考试结束了，大家从初中进入高中已经半个学期了。在此期间，大家一定会感到不适应。进人高中后，学习就登上了一个新台阶。新的教材、新的教学要求，在大家面前设下一道道难关。因此很多同学在诸多方面就出现了很多不适应。 如今，我们的成绩有目共睹，有喜有忧，但无论如何，这都已经成为了过去，我想说的是：山外有山，成绩好的同学，百尺竿头，更进一步，成绩不尽人意的同学查找原因，迎头赶上。期中考试后，我们该做的最重要的是查找问题，找出不足，勿需讳言，我们也应该清醒地看到，在我们个别同学中还有许多问题，各学科发展不平衡，同学们的成绩还存在很大的差距，我们中有些同学的学习态度还很不端正，学习目的不明确，行动不自觉，上课听课不专心，学习气氛不浓厚导致成绩不好。有些同学还想用初中的学习方式对待高中的学习，在老师的“卡压”下学习，在家长的训斥中读书，进入高中一旦松开这些，就没有学习的自觉性，须知高中学习的主动性比什么都重要，内因远远大于外因。 我依稀记得，在军训场上我们挥汗如雨，我们严于律己。尽
管军训早已远去，但我们不该忘记在军训时宣下的誓言，我们宣誓：要把军人的作风纪律融入到我们的学习生活中，刻苦学习，努力拼搏。现在，有大好的机会摆在我们面前，只要我们去珍惜每一个学习机会，不放过课堂上老师讲的每一个重点，不落下课后布置的每一项作业，我们就能兑现我们的誓言，实现我们的梦想! 说到梦想，我相信我们都有自己的梦想。在我们中考报考志愿，选择高中而不是职高的时候，我们的大学梦就已经很明确了，不是么?班里有一个同学曾经问过我：你认为人生什么时候最美好?她给我的回答是上大学的时候。是的，大学是美好的，我一直怀揣着这一梦想，在他的驱使下，我每天认真听课，努力学习。其实，我和大家一样，有时睡眠不足，上课昏昏欲睡。每到这时，我就不停在心里对自己说，不能睡，也许就是打个盹的功夫，就把重点错过了，也许到了高考时，就因为这个知识点没掌握而与大学梦失之交臂!于是我坚持到了下课，坚持到了放学。在这里，我想和大家分享一下我防止犯困的小秘诀，在你觉得你快睡着之前，盯着老师，在老师问一个问题之后，快速大声回答，刺激你的神经，这样睡意就会渐渐消失，而且这堂课还会非常高效。在你下次犯困的时候，不妨试试这一方法。 除了课堂听讲，培养自学习惯也是学习的关键。在初中大部分同学是在老师的督促检查下学习的，没有自学习惯，但进

高一物理期中考试总结整理(教师版) 【】马上就要期中考试了，小编为大家整理了高一物理期中考试总结，供大家参考，希望大家喜欢。 高一物理期中考试总结 这次期中考试,我校高一备课组自行命题。范围是《运动的描述》,《匀变速直线运动的研究》。题型是选择题10题共40分，实验题2题共14分,计算题4题共46分.考虑到这是升上高中后的第一次大型考试,试题相对较容易,平均分期望值为60分左右.但由于我们复习时间比较紧张,学生基础薄弱,考试结果年段平均分为52.7,没有达到了我们的要求，需要我们继续改进教学方法。 学生答卷中暴露出的主要问题及对策 1 基本概念和规律的理解不透彻 不少学生还没有顺利地实现从初中到高中的过渡,学习方法还用初中的那一套,死记硬背公式,对概念和规律的理解还停留在表面上,似懂非懂.从选择题的答题情况分析,可看出部分学生对基本概念和基本规律的理解不透彻,胡乱猜选答案;从计算题第8,9,13题的答题看出学生对匀变速运动的基本公式理解不清,运用不熟练,解题时乱套公式;从计算题第10题的答题看出学生对自由落体运动规律没真正理解,第16小题对追击问题不熟练,不懂得抓住关键点来计算.今后要加强学习方法的指导,一些初中的过时的学习方法要敢于抛弃,探索适
合于自己高中学习的正确的学习方法.特别是要不断对学生强调学物理重在理解,不要把物理变成无理. 2 实验题做得不理想 实验题中一道是根据纸带分析运动性质并求速度,另一道是考查打点计时器测定加速度的实验器材,两题通过率都较低.今后我们的实验课教学要讲效率,培养学生良好的实验习惯,讲清实验原理,步骤,数据处理和误差分析等,争取把每个实验课堂过关,提高实验能力. 3 分析物理过程的能力较差 这次考试发现学生对运动过程的分析比较混乱.例如计算题第14题空降兵先做自由落体运动后做匀减速直线运动; 第15题是研究竖直上抛运动特点;第16题刚好相遇的临界点是刚要追上时两车速度相同.许多学生不能正确分析以上三题的运动过程.今后解运动学问题时,要求学生认真审题,明确物理图景,画出物理过程示意图,再运用所学过的运动学公式解题. 4 解题不够规范 第13,14,15,16题计算题，解答时没有写出必要的文字说明,有的学生甚至连解字都没写.我们今后教学中解题规范要常抓不懈,减少考试中不必要的失分. 5 班级之间不够平衡 班与班之间平均分最高分与最低分相差约10分.科任老师对

高中物理教师期中考试总结 高中物理教师期中考试总结 这次期中考试,我校高一备课组自行命题。范围是《运动的描述》,《匀变速直线运动的研究》。题型是选择题10题共40分，实验题2题共14分,计算题4题共46分.考虑到这是升上高中后的第一次大型考试,试题相对较容易,平均分期望值为60分左右.但由于我们复习时间比较紧张,学生基础薄弱,考试结果年段平均分为52.7,没有达到了我们的要求，需要我们继续改进教学方法。 学生答卷中暴露出的主要问题及对策 1基本概念和规律的理解不透彻 不少学生还没有顺利地实现从初中到高中的过渡,学习方法还用初中的那一套,死记硬背公式,对概念和规律的理解还停留在表面上,似懂非懂.从选择题的答题情况分析,可看出部分学生对基本概念和基本规律的理解不透彻,胡乱猜选答案;从计算题第8,9,13题的答题看出学生对匀变速运动的基本公式理解不清,运用不熟练,解题时乱套公式;从计算题第10题的答题看出学生对自由落体运动规律没真正理解,第16小题对追击问题不熟练,不懂得抓住关键点来计算.今后要加强学习方法的指导,一些初中的过时的学习方法要敢于抛弃,探索适合于自己高中学习的.正确的学习方法.特别是要不断对学生强调学物理重在理解,不要把物理变成"无理". 2实验题做得不理想
实验题中一道是根据纸带分析运动性质并求速度,另一道是考查打点计时器测定加速度的实验器材,两题通过率都较低.今后我们的实验课教学要讲效率,培养学生良好的实验习惯,讲清实验原理,步骤,数据处理和误差分析等,争取把每个实验课堂过关,提高实验能力. 3分析物理过程的能力较差 这次考试发现学生对运动过程的分析比较混乱.例如计算题第14题空降兵先做自由落体运动后做匀减速直线运动;第15题是研究竖直上抛运动特点;第16题刚好相遇的临界点是刚要追上时两车速度相同.许多学生不能正确分析以上三题的运动过程.今后解运动学问题时,要求学生认真审题,明确物理图景,画出物理过程示意图,再运用所学过的运动学公式解题. 4解题不够规范 第13,14,15,16题计算题，解答时没有写出必要的文字说明,有的学生甚至连"解"字都没写.我们今后教学中解题规范要常抓不懈,减少考试中不必要的失分. 5班级之间不够平衡 班与班之间平均分最高分与最低分相差约10分.科任老师对弱班要特别加强师生之间的情感交流,帮助学生增强学习信心,激发学习热情,要做好分层教学,偏爱后进生,针对性辅导和布置作业. 通过这次考试，我们要把以前好的做法要继续坚持，继续加强集体备课,深入研究高中物理课程标准;开好每周一次的"物理研究课",课后认真评课;编写出较高质量的适用于我校学生的自编练习;注重
