1. By tradition, the 1(?) of Thanksgiving Day is to commemorate the early successful harvests celebrated by the white settlers 2(?) arrived in the New World.

The first celebrations in what is now Canada were held in Newfoundland in 1578 by the English navigator, Martin Frobisher. These were the usual harvest festivals after the year’s work. The first recorded celebration in 3(?) is now the USA 4(?) sometime in autumn in 1610, celebrated by the colonists at Jamestown, Virginia. 5(?), for these colonists it was not so much a celebration of the harvest — but the fact that supply ships had arrived 6(?) England. Due to the terrible winter 1609-1610, the colonists’ numbers had been 7(?) from 490 down to 60, and they were desperate. The first harvest-related Thanksgiving in the later USA was in 1621 at Plymouth, Massachusetts, a year 8(?) the arrival of the Pilgrims on the Mayflowe, and after their first successful year.

So the source of the Thanksgiving Day celebration in the USA is a combination of 9(?) farming harvest celebrations, the survival of the Jamestown colonists by the arrival of the supply ships, and the celebration of the Pilgrims. 10(?) the reason for the tradition, the Thanksgiving Day in our industrial society today is the time for family. （10分）(1) 第1空（1分）A.result

1. Have you ever found yourself completely disgusted by your own performance during a job interview? I have, and it was all my own fault. Here’s my worst job interview experience, along with some of the lessons I’ve learned sin ce.

Several years ago I wanted to be a federal officer. So I applied for several job openings, went through written tests and even managed to get an interview. I was very excited and felt prepared for anything. When I went in for the interview, I felt almost invincible.

That feeling lasted until they started asking me for specific examples of experience, particularly those dealing with teamwork and communication. My job at the time was almost all teamwork, yet, I blanked on examples. I lamely answered those questions by explaining that my previous job required teamwork and communication all the time without any detail.

In my experience, most interviewers will ask for a specific example at some point and they want to know exactly how you dealt with the issue. You’d better go over some examples

concerning your abilities before the interview and this might help you avoid going blank on those questions.

Another question they asked was, “What is your biggest weakness?” I gave the overused, canned ans wer of, “I’m a perfectionist, and it’s such a problem.” However, the old “make your weakness sound like strength” trick is clichéd, and failed me miserably. I actually saw one of my interviewers roll his eyes.

Interviewers don’t want to hear that you’re a perfectionist. Too many people say that. Here’s how that works: Regardless of the job, think of a skill you have, but aren’t great at, that may be related but not important to the position you’re seeking. Explain how you want to improve and what you’re doing. It shows your desire to grow, along with an understanding that you’re human.

There will always be questions that can rattle you during the job interview, but as long as you are well-prepared and always remain true to yourself, you will find the right job eventually! （10分）(1) The author applied for several jobs and got an interview successfully. （2分）错误

2. One Mother’s Day morning a troubling thought crossed my mind. You’ve never, ever, in your whole life, told your mother you love her. What if she dies and you have to live with that for the rest of your life?

What reason did I have for not telling Mum I loved her? I didn’t know I had to! Such words were never spoken in our home. My parents loved each other and they loved their five children, but our f amily didn’t hug and say mushy things such as “I love you.”

My parents were also loved by their parents, but there were no hugs and sweet talk there either. Mum’s mother had been a child immigrant to the country and worked as a domestic helper when she was just eight years old. Before that, she had lived in an orphanage in London. She had no memories of her mother. None.

Naturally, my grandmother wasn’t big on outward shows of affection. Hence, my mother didn’t receive any I-love-you either, and she wasn’t good at giving affection to her children,

except when they were in the baby and toddler stages.

Everyone in my family was supposed to translate warm meals, clean beds and good clothing as “love.” But, seeing love in action doesn’t make up for failing to hear the words “I love you”.

That Mother’s Day, I felt God speaking to me, telling me to break down that barrier. He told me that my mother needed to hear me say, “I love you.” And I needed to say it!

Mum lives three hours away, so it wasn’t possible to tell her face-to-face. I phoned.

At first, I wished her a happy Mother’s Day. Then we talked about the weather, other members of the family and Dad’s health. All the while, the words “I love you” were burning in my mind. When you’ve never said those words to someone, they don’t just roll off your tongue.

Finally, when I felt our conversation winding down, I blurted, “I love you, Mum.”

She said, “I love you too, dear,”just as if she’d been saying it to me all my life. （10分）(1) There are five children in the author’s family and they always say nice things to each other. （2分）错误

五. 阅读理解选择（共20题,共40分）

1. Alfred Nobel, a chemist, a great inventor and a peace-lover, was born on October 21, 1833 in Sweden. A little over a year before he died, he wrote his will and left about 94 percent of his money to the founding of five prizes, including physics, chemistry, medicine, literature and peace. According to Nobel’s will, the Peace Prize should be awarded to peace-lovers and those who have done the most or the best work for the peace of the world in the last years. Unluckily, Alfred did not see peace in his time. He died alone on December 10, 1896 suffering great pain.

In his will, Nobel did not leave an explanation why he founded a prize for peace. The prizes for chemistry and physics were easy to be seen as he was a trained chemical engineer. But the reason behind the peace prize is less clear. According to some people, his friendship with Bertha V on Suttner may have deeply influenced his decision to include peace as one of the prizes. She is a peace activist and the first woman peace prize winner. But some others said because Nobel had

some dangerous inventions, the peace prize was Nobel’s way to make up for the possible damage. But no one has got an answer for sure.

It is also unclear, while the other four Nobel prizes were managed in Sweden, why Nobel wished the Peace Prize to be managed in Norway instead. Some experts reasoned at the time of Nobel’s death, Sweden was controlling Norway by force, so Nobel might c onsider Norway a better place for the peace prize.

The Peace Prize has been awarded for more recent or immediate achievements than the other four Nobel prizes. Before World War I, the prize was often awarded to pioneers of the organized peace movements and active politicians working for international peace and agreements. Since World War II, the Peace Prize winners have been selected from areas like arms control, peace talk, human rights and work aimed at creating a better organized and more peaceful world. （10分）(1) Alfred Nobel is all but a(n) ___________. （2分）A.chemist

B.scientist

C.engineer

D.peace prize winner

答案：D

(2) What may be the most possible reason for the founding the Peace Prize? （2分）A.Nobel wanted Bertha Von Suttner to share his money.

B.Nobel was a scientist and wanted to praise other scientists.

C.Nobel wanted to do something for the peace of the world.

D.Nobel had a lot of money and had no son or daughter.

答案：C

(3) Why was the Nobel Peace Prize managed in Norway instead of Sweden according to some experts? （2分）A.Nobel believed he must do something for Norway.

B.Norway is Nobel's hometown.

C.Sweden was not so peace-loving at the time when Nobel founded the prize.

D.Sweden was stronger and richer at that time.

答案：C

(4) A Nobel Peace Prize winner can’t be a(n) ____________. （2分）A.politician

B.terrorist

C.activist

D.peace lover

答案：B

(5) Which of the following statements is true according to the text? （2分）A.Till now people have had no idea why Alfred Nobel set up the prize for physics.

B.Alfred Nobel may have been worried about the damages caused by his dangerous inventions.

C.The standard that the Peace Prize committee adopted to award the Peace Prize must be totally different before and after World War I.

D.The purpose of setting up the Peace Prize is just the same with that of the other four Nobel Prizes.

答案：B

2. " Michael Jackson was known as the “King of Pop”, but his huge success as a performer was not always easy.

Born in Gary, Indiana in 1958, Jackson was the seventh of nine children. He was five years old

when he began singing with his brothers in a group called The Jackson 5, and eleven when their first album was released.

The Jackson 5 became an immediate success. Their music set records. Michael, the lead singer and energetic dancer, was the star of the group.

In the 1970s, the group shortened their name to The Jacksons. Three years later, Jackson released “Thriller” on his own. The album was not just t he best selling album of all time, it also won many major Awards. And it helped establish the popularity of a new form of entertainment, Music Video.

Michael Jackson was a huge success, but he was also a very troubled man. He had many operations to change his face. He sometimes acted and spoke in a childlike way, for example, he once bought a huge property in California which he called “Neverland” after the children’s story “Peter Pan”. And he suffered from injuries and illness that led him to take many kinds of pain-killing medicines.

In 1993, a thirteen-year-old boy accused him of sexual abuse. Ten years later, a similar accusation led to a criminal trial which began in 2005. A jury cleared Jackson of all charges. He called the trial the hardest thing he had ever met in his life.

After his 2005 trial, the singer spent much of his time in Europe and the Middle East. He returned to the United States with the aim to make a victorious comeback. Michael Jackson died of heart failure on June 25, 2009, just days away from holding concerts in London.

《马原》大学期末考试必背知识点汇总

最新《马原》大学期末考试必背知识点汇总 第一章马克思主义是关于无产阶级和人类解放的科学 1、《共产党宣言》的发表，标志着马克思主义的公开问世 2、马克思主义产生的社会根源（或经济、社会历史条件）是资本主义经济的发展 3、马克思、恩格斯完成了从唯心主义同唯物义、从革命民主主义向共产主义的转变，为创立马克思主义奠定思想前提 4、在马克思主义创立过程中，第一次比较系统地阐述了历史唯物主义基本原理的着作是《德意志意识形态》 5、在马克思主义的经典着作中，被誉为“工人阶级的圣经”的着作是《资本论》 6、马克思主义经济理论的基石是剩余价值理论 7、世界上第一个无产阶级政党是共产主义者同盟 8、马克思主义理论区别于其他理论的显着特征是实践性 第二章世界的物质性及发展规律 9、唯物主义与唯心主义的对立和斗争中交织着辩证法与形而上学的对立和斗争 10、全部哲学，特别是近代哲学的重大的基本问题，是思维和存在的关系问题；唯物主义和唯心主义这两个专门的哲学术语有着特定的含义和确定的标准，不能随意乱用，也不能另立标准，否则会造成混乱。这里所说的特定含义和确定标准是指对世界本原究竟是物质还是精神的回答；存在和思维是否具有同一性，是哲学基本问题的第二方面的内容，对这个问题的不同回答，是划分可知论和不可知论的标准， 11、唯物主义一元论同唯心主义一元论对立的根本点在于世界本原问题 12、物质的唯一特性是客观实在性，“客观实在”是指存在于人的意识之外，不以人的意志为转移 13、相信“意念移物”，甚至相信可以用意念来直接改变物质结构，就是信奉主张精神主宰客观物质世界的主观唯心论 14、“心诚则灵，心不诚则不灵”的说法是夸大了意识能动作用的唯心主义观点 15、哲学物质概念与自然科学关于具体的物质形态和物质结构的概念之间共性与个性的关系（不是整体和部分的关系、系统与要素的关系） 16、列宁对辩证唯物主义物质范畴的定义是通过物质与意识的关系界定的 17、物质和意识的对立只有在非常有限的范围内才有绝对的意义，超过这个范围便是相对的了，这个范围是指物质和意识何者为第一性 18、对同一张事物的不同看法都是客观事物的主观映象 19、意识是客观世界的主观映象，这说明意识是客观精神的主观映象 20、“思想实验”体现了意识活动的创造性 21、运动是物质的存在方式和根本属性 22、“寒路神麦正当时”说明一切事物都处在永恒的运动、变化和发展之中 23、物质决定意识，意识对物质具有反作用。这种反作用也就是意识的能动作用，即人特有的积极认识世界和改造世界的能力和活动。 24、运动是物质的根本属性，是物质的存在方式 25、运动是物质的存在方式和根本属性，物质是运动着的物质，脱离运动的物质是不存在的 26、柏格森所说的运动变化不是指任何具体的事物的运动变化，而只是纯粹的“动作”，是没有物质承担者的运动
