When Christopher Columbus landed on the then unnamed Costa Rica in 1502, he saw many Indians wearing gold earrings. So he thought the land must be rich in gold. He named the place Cos ta Rica, which means “rich coast” in Spanish.

Though little gold was found, Costa Rica today is indeed rich with coffee and bananas. Coffee is the most important product in Costa Rica and most of it is exported (出口) to other countries like America and Wes t Germany. Bananas are the country’s second most important export.

Costa Ricans also grow many other crops such as fruits, corn and beans for their own use. Costa Ricans love colors and their houses are painted in bright colors.

Education is very important to the Costa Ricans. Almost every village has a school and education is a must for children between seven and fourteen years of age. Boys and girls go to separate (单独的) schools. Classes begin in March and end in November. The other three months of the year are harvest time and the children have to help their parents to pick coffee beans.

B ★

Christian Eijkman, a Dutch doctor, left the Netherlands for the island of Java. Many people on the island had a disease called beri-beri. He was going there to try and find a cure.

At first, Eijkman thought some kind of germ (细菌) caused beri-beri. He raised some chickens. He didn’t eat them, but made experiments on them. The local people were quite surprised at that. One day he noticed that his chickens became sick when they were fed the food most Javanese ate — refined white rice (精炼米). When he fed them with unrefined rice, also known as brown rice, they recovered. Eijkman realized that he had made an important discovery — that some things in food could prevent disease. These things were named vitamins (维生素). The Javanese were not getting enough vitamins because they had actually removed the part that contains vitamins. Later, other diseases were also found to be caused by the lack of vitamins in a person’s food.

Today many people know the importance of vitamins and they make sure they have enough vita mins from the food they eat. If they don’t, they can also take vitamin pills.

61. The underlined word “cure” in Paragragh 1 probably means ______.

A. a medical treatment

B. a kind of vitamin

C. a kind of germ

D. a kind of rice

62. Christian Eijkman went to the island of Java to ______.

A. spend his holiday

B. find ways to grow better crops

C. do some research about the island

D. help the Javanese with their illness

63. Why did Christian Eijkman raise some chickens?

A. To eat them.

B. To carry out his experiments.

C. To give the Javanese a surprise.

D. To make money by selling them.

64. If a person doesn’t get enough vitamins in his diet, he’d better ______.

A. eat more rice

B. eat more meat

C. eat some chicken

D. eat vitamin pills

65. We can learn from the passage that ______.

A. beri-beri was caused by chickens

B. the Javanese didn’t like vitamins

C. Christian Eijkman’s experiment was successful

D. the Javanese’s disease was caused by a kind of germ

C ★★

America is a mobile society. Friendships between Americans can be close and real, yet disappear soon if situations change. Neither side feels hurt by this. Both may exchange Christmas greetings for a year or two, perhaps a few letters for a while —then no more. If the same two people meet again by chance, even years later, they pick up the friendship. This can be quite difficult for us Chinese to understand, because friendships between us flower more slowly but then may become lifelong

feelings, extending (延伸) sometimes deeply into both families.

Americans are ready to receive us foreigners at their homes, share their holidays, and their home life. They will enjoy welcoming us and be pleased if we accept their hospitality (好客) easily.

Another difficult point for us Chinese to understand Americans is that although they include us warmly in their personal everyday lives, they don’t show their politeness to us if it requires a great deal of time. This is usually the opposite of the practice in our country where we may be generous with our time. Sometimes, we, as hosts, will appear at airports even in the middle of the night to meet a friend. We may take days off to act as guides to our foreign friends. The Americans, however, express their welcome usually at homes, but truly can not manage the time to do a great deal with a visitor outside their daily routine. They will probably expect us to get ourselves from the airport to our own hotel by bus. And they expect that we will phone them from there. Once we arrive at their homes, the welcome will be full, warm and real. We will find ourselves treated hospitably.

For the Americans, it is often considered more friendly to invite a friend to their homes than to go to restaurants, except for purely business matters. So accept their hospitality at home!

66. The writer of this passage must be ______.

A. an American

B. a Chinese

C. a professor

D. a student

67. Which of the following statements is TRUE according to the passage?

A. Friendships between Americans usually extend deeply into their families.

B. Friendships between Americans usually last for all their lives.

C. Americans always show their warmth even if they are very busy.

D. Americans will continue their friendships again even after a long break.

68. From the last two paragraphs we can learn that when we arrive in America to visit an American friend, we will probably be ______.

A. warmly welcomed at the airport

B. offered a ride to his home

C. treated hospitably at his home

D. treated to dinner in a restaurant

69. The underlined words “generous with our time” in Paragraph 3 probably mean ______.

A. strict with time

B. serious with time

C. careful with time

D. willing to spend time

70. A suitable title for this passage would probably be “______”.

A. Friendships between Chinese

B. Friendships between Americans

C. Americans’ hospitality

D. Americans’ and Chinese’s views of friendships

D ★★★

The other day I heard a few local musicians talking:

“I hate all the terrible pian os in this town. I hate that rubbish they play on the radio. They can’t even understand a bit of music.”

“I’m never playing in that club again. Too many drunks and nobody listens to us.”

But, one younger musician said, “There are a few clubs that book my band a few nights a month, and I’m trying to find other places to play. I’m also looking to book a few summer festivals this year.”

I’ve heard that you are the average of the five people whom you spend the most time with, or to put it another way, you are who your friends are.

Attitudes are important. Whether they’re positive or negative, they’re rubbing off on you. If you’re around people who complain about lack of work and about other musicians, or blame (责怪) others, and you play the role of victim (受害者), chances are you will start to as well. So it’s time to take a look at the people you call “friends”.

This is an easy exercise: Make a list of the people who you hang out with, and simply stop spending time with the negative people on your list. Set a new standard (标准) for yourself and don’t become friends with people who fall below that standard.

Keep successful people around you and your own chances for success will be much better. Ask them how they do it. Ask if they will help you get the work you’re looking for, or maybe give you some advice to help you on your career path.

71. Which of the following would be the best title for this passage?

A. A friend in need is a friend indeed

B. How to make friendship last for ever

C. You are who your friends are

D. Friends are the most important in one’s success

72. The underlined sentence “they’re rubbing off on you” in Paragraph 6 means ______.

A. they’ll push you ahead

B. they’ll influence you

C. they’ll cover your shortcomings

D. they’ll help you achieve your goal

73. The musicians’ words at the beginning are written mainly to show ______.

A. the musicians’ living conditions are quite poor

B. people have poor taste in music

C. people have different attitudes towards the same thing

D. young people have greater chances of succeeding

74. By taking the exercise mentioned in Paragraph 7, you can ______.

A. improve a lot in making more friends

B. come to the right way of making friends

C. develop a better relationship with your friends

D. arrange the time with your friends properly

75. The passage is mainly written for ______.

A. musicians

B. managers

C. negative people

D. people wanting to succeed

简单机械单元测试题 含答案(word)

简单机械单元测试题含答案（word） 一、简单机械选择题 1．如图甲所示，是建筑工地上的塔式起重机示意图，它是通过电动机带动如图乙所示的滑轮组起吊物料的．如果这个滑轮组把6×103N的重物在10s内匀速提升l0m，绳索自由端的拉力F=2.1×103N，不计一切摩擦和绳重，则下列说法中正确的是 A．拉力做的功是2.1×104J B．拉力F的功率是2.1×103W C．该滑轮组的动滑轮共重300N D．该滑轮组的机械效率是80% 【答案】C 【解析】 由图乙知道，滑轮组绳子的有效股数是n=3，即绳子自由端移动的距离是： s=3h=3×10m=30m，所以拉力做的功是：W总=Fs=2.1×103 N×30m=6.3×104 J，故A错误；拉力做功的功率是：P=W总/t=6.3×104N/10s=6.3×103 W，故B错误；若不计绳重和摩擦，则由F=（G+G动）/n可知，动滑轮的总重是：G动 =nF-G=3×2.1×103 N-6×103 N=300N，故C正确；拉力做的有用功是：W有=Gh=6×103 N×10m=6×104 J，滑轮组的机械效率是：η=W有/W 4J/6.3×104J×100%≈95.2%，故D错误，故选C． 总×100%=6×10 2．关于机械效率的问题，下列说法中正确的是（） A．做的有用功越多，机械效率一定越高B．单位时间内做功越多，机械效率一定越高 C．省力越多的机械，机械效率一定越高D．额外功在总功中所占比例越小，机械效率一定越高 【答案】D 【解析】 【详解】 A、做功多，有用功不一定多，有用功占总功的比例不一定高，所以机械效率不一定高，故A错误； B、有用功占总功的比例与单位时间内做功多少无关，故B错误； C、省力多的机械的机械效率往往偏低，故C错误； D、额外功在总功中所占比例越小，说明有用功在总功中所占的比例越大，机械效率就越高，故D正确；故选D． 【点睛】 ①总功＝有用功+额外功；②有用功和总功的比值叫机械效率；③由机械效率的定义可知，机械效率的高低只与有用功在总功中所占的比例有关，与做功多少、功率大小无关． 3．山区里的挑夫挑着物体上山时，行走的路线呈“S”形，目的是 A．加快上山时的速度 B．省力

She was helping him compose (作曲) his first piece of music. Sergei was only five years old. He had overheard his parents discussing a terrible famine (饥荒) in India. The picture Sergei had of those hungry people in his mind caused him to write a story, in the form of musical notes. Sergei could not read music, so he picked out a tune on the piano keys, and his mother recorded the notes. Sergei titled it “Indian Gallop.” Sergei's mother began giving him piano lessons for 20 minutes a day, and his ability grew quickly. She had a great love for music, too, and Sergei often lay awake in bed at night and listened to her play the piano. Sergei's parents found a famous music teacher for him. The teacher shouted at Sergei when he didn't practice reading and playing music. Sergei later wrote, “I wanted to compose great musical plays, and instead I was given all sorts of boring tasks.” Yet he persisted with his studies and grew up to be a great composer. In 1936 a children's theater asked Sergei to write music that would teach children about different instruments. He was happy and wrote the piece in a week, calling it Peter and the Wolf. Sergei's Peter and the Wolf was enjoyed by children as well as adults. The first time Sergei played the piece on the piano, the children listening to it loved it so much that they made him play the ending three extra times. He was excited. Today Sergei Prokofiev is remembered not only for his contributions (贡献) to classical music, but also for his sense of fun. 21. When he was five, Sergei _____. A. could read music

人教版高一英语必修二单元测试题全套带答案 Unit 1 单元测试题 第二部分：阅读理解（共两节，满分40分） 第一节（共15小题；每小题2分，满分30分） 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 Insects (昆虫) are a very healthy food. They have almost as much protein (蛋白质) as meat from a pig or cow and are low in fat. Eating insects is also very good for the environment since they need less land and water than larger animals. Marcel Dicke, who studies insects, explained in a talk how insects also produce more meat from the food they eat. For example, imagine a farmer feeds a cow 10 pounds of food. Those 10 pounds of food produce about 1 pound of meat for people to eat. However, imagine the farmer gives a certain number of insects 10 pounds of food. Those 10 pounds of food produce 9 pounds of meat for people to eat! Eating more insects can also help people in poor areas. Many people can raise and sell insects, which can provide jobs and food. But insects will not replace (替代) animal meat very quickly. First, people in some countries would have to change how they think about eating insects. Many people in North America and Europe eat a lot of meat like beef and pork. But they do not traditionally eat insects. In fact, for many people in the west, eating insects sounds crazy! They believe insects are dirty and dangerous. Insects make them feel uncomfortable. Some people are trying to deal with this problem. For example, David George Gordon wrote a book named “The Eat-A-B ug Cookbook”, which tries to show people that insects can be delicious. Other insect experts travel around telling people about the benefits (好处) of eating insects. But they still have a lot of work to do. 21. Eating insects _____. A. is not healthy B. makes people put on fat
