Farm days were happy but there were sometimes some things you didn’t expect. One day, I was sent by my father to buy some tools for our farm. As a 17-year-old boy, I liked 16 better than driving our truck, 17 this time I couldn’t cheer up. My father had told me I’d have to ask for credit(赊账) at the store.Seventeen is a/an 18 age, when a young man wants respect more than anything else. It was 1976, and the ugly 19 of racial discrimination(歧视) was still a fact of life. I had seen my friends ask for credit and then stand, head down, while the store owner 20 whether they were good for it. I knew black youths just like me who were 21 like thieves by the store clerk each time they went into a store.My family was honest. We paid our debts. But before harvest, cash was short. Would the store owner 22 us?Wall James, the store owner, stood behind the cash desk, talking to a farmer. I nodded as I passed him on my way to the shelves. When I brought my 23 to the cash desk, I said 24 , “I need to put this on credit.”The farmer gave me a 25 look. But Wall’s face didn’t change. “Sure,” he said quickly. “Your dad is 26 good for it.” He 27 to the other man. “This boy is one of John Tuck’s sons.”The farmer nodded in a neighborly way. I was filled with pride. “John Tuck’s son.” Those there words had opened a door to an adult’s respect and trust.That day I discovered that the good name my parents had 28 brought our whole family the respect of our neighbors.

If you intend using humor in your talk to make people smile, you must know how to identify shared experiences and problems. Your humor must be relevant to the audience and should help to show them that you are one of them or that you understand their situation and are in sympathy with their point of view. Depending on whom you are addressing, the problems will be different. If you are talking to a group of managers, you may refer to the disorganized methods of their secretaries; if you are addressing secretaries, you may want to comment on their disorganized bosses.Here is an example, which I heard at a nurses' gathering, of a story which works well because the audience all shared the same view of doctors. A man arrives in heaven and is being shown around by an Angel. He sees wonderful accommodations, beautiful gardens, sunny weather and so on. Everyone is very peaceful, polite and friendly until, waiting in a line for lunch, the new arrival is suddenly pushed aside by a man in a white coat, who rushes to the head of the line, grabs his food and stomps over to a table by himself. "Who is that?" the new arrival asked the Angel. "Oh, that's God." came the reply, "but sometimes he thinks he's a doctor."If you feel awkward being humorous, you must practice so that it becomes more natural. Include a few casual and apparently off-the-cuff remarks which you can deliver in a relaxed and unforced manner. Often it's the delivery which causes the audience to smile, so speak slowly and remember that a raised eyebrow or an unbelieving look may help to show that you are making a light-hearted remark.Look for the humor. It often comes from the unexpected. A twist on a familiar quote "If at first you don't succeed, give up" or a play on words or on a situation. Look at your talk and pick out a few wordsor sentences which you can turn about and inject with humor.31:To make your humor work, you are supposed to ________.A. make fun of the disorganized people.B. address different problems to different people.C. show sympathy for your listeners.D. take advantage of different kinds of audience32: The joke about the doctors implies that, in the eyes of nurses, they are ________.A. very clear about their godlike roleB. very busy even during lunch hours.C. impolite to new arrivalsD. not fond of having lunch with the nurses33:What’s the possible meaning of the underlined word in paragraph3? ________.A. intentionalB. urgentC. unpreparedD. excellent34:To achieve the desired result, humorous stories should be delivered ________.A. as casually as possibleB. as awkwardly as possibleC. in well-worded languageD. as quickly as possible35: The best title for the text may be ________.A. Different Humor methodsB. Various kinds of humorC. Add humor to speechD. Use humor effectively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,选项中有两处为多余选项。

解答:∵三角形斜边长6cm, 面积为6cm 2,∴三角形斜边上的高为2cm斜边上的高把三角形分成两个直角三角形,旋转得到两个圆锥,两个圆锥的底面半径等于1cm ,两个圆锥的高之和等于6cm ,∵圆锥体积 =(底面积×高)÷3,∴这两个圆锥的体积 =(π×22×6)÷3 = 8π (cm 3)2.略3.甲:乙=4:5,甲比乙少多少?解答:乙为5份,甲为4份,甲比乙少1份,1份占乙的1/5。
4.口袋中有红、黑、白、黄四种球给10个,他们的外形和重量都一样,至少摸出多少个球才能保证有2个颜色相同的球?解答:略。
5.选A 的有10人,占20%;选B 的有16人;选C 的占n%;选D 的有6人,占12%,求n 为多少? 解答:∵选A 的10人,占20%,∴总人数是50人。
选C 的人数50-10-16-6=18人,占18/50=36%。
6.如图,三角形纸板、正方形纸板、圆形纸板面积相同,都为60平方厘米,阴影部分面积和为40平方厘米,3张纸板盖住的总面积为100平方厘米,则黄色部分面积为多少?解答:∵ 1白色 + 2阴影 + 3黄色 = 1801白色 + 1阴影 + 1黄色 = 100∴ 1阴影 + 2黄色 = 80∵1阴影 = 40∴2黄色 = 40∴1黄色 = 207.一项工程,甲单独完成需要30天,乙单独完成需要60天,则两人合作需要多少天完成?解答:假设共有60份工作,甲的工效是2份/天,乙的工效是1份/天,工效和是3,合作要20天。
8.甲乙共有20多本书,甲给乙若干本,乙就比甲多3/4,乙给甲同样多本书,甲就是乙的1.2倍,甲乙一共有多少本书?解答:假设第一次给过之后,甲有4份书,那么乙就有7份书,他们共有11份书,一份为1本、3本都不行,只有当一份是2本时,符合20多本的要求,即22本。
