Each passage is followed by several questions or unfinished statements. For each of them there are four choices marked A, B, C and D. Choose the one that fits best according to the information given in the passage you have just read.(A)Rosalind Franklin always liked facts. She was logical and precise, and impatient with things that were otherwise. She decided to become a scientist when she was 15. She passed the examination for admission to Cambridge University in 1938, and it sparked a family crisis. Although her family was well-to-do and had a tradition of public service and charity, her father disapproved of university education for women. He refused to pay.An aunt stepped in and said Franklin should go to school, and she would pay for it. Franklin’smother also took her side until her father finally gave in.She was invited to King’s College in London to join a team of scientists. The leader of the team assigned her to work on DNA with a graduate student. Franklin’s assumption was that itwas her own project. The laboratory’s second-in-command, Maurice Wilkins, was on vacation atthe time, and when he returned, their relationship was puzzling. He assumed she was to assist hiswork; she assumed she’d be the only one working on DNA. They had powerful personalitydifferences as well: Franklin direct, quick, decisive, and Wilkins shy, hesitant, and passive.In 1953, Wilkins changed the course of DNA history by disclosing, without Franklin’s permission, her Photo 51 to competing scientist James Watson, who was working on his own DNA model with Francis Crick at Cambridge. Upon seeing the photograph, Watson said, “My jaw fell open and my pulse began to race,”according to author Brenda Maddox who wrote the book Rosalind Franklin: The Dark Lady of DNA.The two scientists did in fact use what they saw in Photo 51 as the basis for their famous model of DNA, which they published on March 7, 1953, and for which they received a Nobel Prize in 1962. Crick and Watson were also able to take most of the credit for the finding: they included a footnote acknowledging that they were “stimulated by a general knowledge” of Franklin’s and Wilkin’s unpublished contribution, when much of their work was rooted in Franklin’s photo and findings. Franklin didn’t know that these men based their article on her research, and she didn’t complain either, likely as a result of her upbringing. Franklin “didn’t do anything that would invite criticism… (that was) bred into her,” Maddox said.66. Wilkins’ relationship with Franklin was characterized by __________.A. unity and harmonyB. confusion and competitionC. cooperation and miscommunicationD. misunderstanding and conflict67. What does Watson mean by saying “My jaw fell open and my pulse began to race”?A. He was confused that Crick had not made this discovery.B. He was surprised that Wilkins had discovered this information.C. He was satisfied with the importance of Photo 51.D. He was anxious about the progress Wilkins and Franklin had made.68. What is Brenda Maddox’s main intention according to the quote in the last paragraph?A. To re-evaluate the importance of the DNA model.B. To criticize King’s College and Cambridge.C. To emphasize Franklin’s importance in science.D. To deny Watson’s and Crick’s contribution to science.69. Franklin’s career as a scientist demonstrates _________.A. that her work was pointing at the most difficult problemB. that she was the only female scientist during the periodC. the importance of DNA in modern scienceD. that perseverance leads to success and recognition of field scientists(B)ReviewsCultual Breaks by Brian AldissReviewed by Paul KincaidBrian Aldiss is an amazing and frustrating writer. When he is on song, hisstyle is forceful, disturbing and delectable. But he is a restless writer. Hecame into his own in the enthusiastic and experimental atmosphere of theNew Wave, and he has been driven to try the new and the different eversince. That he is still experimenting now, 50 years after his firstappearance, is a measure of a man who has never been prepared to settleback on his laurels. The Secrets of Jin-Shei by Alma AlexanderReviewed by Donna McMahonWith so many fantasy novels using European-derived settings and mythology, ancient China makes a refreshing change. The landscape is tempting and yet familiar enough to feel very real, and the author uses magic sparingly, in ways appropriate to her society. This and the complex detail put into the backdrop makes the novel feel very much like historical fiction.Straken by Terry BrooksReviews by Nathan BrazilThe third novel in the High Druid of Shannara series jumps straight backinto the story where it left off. It continues the quest of unlikely hero Penderrin Ohmsford. Now equipped with the means to break in –andback out- of the Forbidding, where his aunt, the overthrown Ard Phys of Druids, is stranded, Pen must first get back to Paranor. His rescue attemptcan only begin from within the chamber where Grianne Ohmsford disappeared. Unfortunately, this will deliver him straight into the hands of those responsible for his aunt’s disappearance.70. The reviewer admires Brian Aldiss’ ability to ___________.A. write so many novelsB. continue to be inventive in his writingC. write disturbing plotsD. have a writing career spanning over four decades71. Why does the setting of Jin-Shei appeal to the reviewer?A. It is a good science of fiction setting.B. It is mysterious.C. It is a less common choice of setting.D. It is very magical.72. Terry Brook’s novel continues a series on ___________.A. the adventures of an unsuspecting hero and his attempts to rescue his auntB. a quest about the High Druid of Shannara in a secret chamber in ParanorC. the disappearance of a druid which foils the plans of the enemiesD. liberating a stranded aunt who is key to the knowledge of the Forbidding (C)Aisling’s mother died at midsummer. She had fallen sick so suddenly that some of the villagers wondered if the fairies had come and taken her, for she was still young and beautiful. She was buried three days later beneath the hawthorn tree(山楂树) behind the house, just as twilight was darkening the sky.Maire Solanya, the village greenwitch, came that evening to perform the old rituals over the grave. She stood at the foot of the mound of black soil. Aisling and her father stood at the head of it, resting on the simple headstone, was the burning candle. Aisling’s father had lit it shortly after Elinor died, and it would burn all night. The gravestone was a plain piece of slate carved with her name: Elinor. Grass and tree roots would grow up around it as the years passed, until it would seem as if it had always been there.Maire Solanya said in her low, clear voice, “Life to life, from breath to breath, we remember Elinor.” She held a round loaf of bread in her hands. She tore off a small piece and ate it, chewing deliberately, before handing the loaf to Aisling’s father. He pulled off his own piece, then passed it to his daughter. It was still warm, and it smelled like her mother’s kitchen after baking. But it hadn’t come from her mother’s hands, and that realization made a lump rise in her throat. The bread was tasteless.Maire Solanya took the loaf from her, its crust(面包皮) gaping open, and placed it on the gravestone next to the candle. Aisling couldn’t shake the feeling that her mother had merely gone out on an errand and would come home at any moment and wonder what the three of them were doing. It didn’t seem possible that she was buried there, at the foot of the hawthorn tree, in the ground. It was easier to believe the village rumors than to sit with the ache inside herself.She remembered those rumors now, while she stood with her father and Maire Solanya in a tense silence. Everyone had always said that Elinor had some magic in her, and everyone knew that fairies – if they existed – were drawn to that. So Aisling’s father had ordered all the old rituals, even though he did not believe in them, just in case. She was not entirely sure what she herself believed, but she knew that her mother would want them to do these rituals for her, and that was enough.When the sun slipped below the horizon, the greenwitch said, “Sleep in peace, Elinor,”and scattered a gold powder over the grave to bind Elinor to the earth. On the freshly turned soil, the gold glittered like fairly dust.73. Aisling and her family are most likely __________.A. fairlies in disquiseB. simple village folkC. wealthy farmersD. experienced bakers74. Maire Solanya performed the rituals in order to __________.A. express thanks to the fairiesB. protect the hawthorn treeC. respect Elinor’s wishesD. capture Elinor’s spirit75. Which of the following does not describe Elinor?A. A believer in magic.B. Practical.C. Skilled at baking.D. Youthful.76. Which statement best describes Aisling’s belief in fairies?A. She is uncertain and finds the idea unsettling.B. She finds the idea comforting but is unsure.C. She is certain they exist and wishes they would bring back her mother.D. She believes strongly in the power of their rituals but not in their existence.77. Why did Aisling find the bread “tasteless”?A. It reminded her of her mother’s absence.B. It was a terribly rude thing to eat at her mother’s funeral.C. Solanya was really a poor baker in the village.D. There had not been sufficient ingredients to make the bread.Section CDirections: Read the passage carefully. Then answer the questions or complete the statements in the fewest possible words.How was it that an American ship came to be sunk by American mines in a port held by American forces?Built in1931, the luxury liner SS President Coolidge was a 10-year veteran(退伍军人) of the Pacific before she was pressed into service by the military and converted to carry troops.On October 26, 1942, towards the end of her first year of World War II service, the Coolidge hit an American mine in the east entrance of the Segond Channel on Espiritu Santo, one of the islands of the New Herbrides(now Vanuatu), and sank in 36 meters of water.Though all but two of the 5000 officers and men aboard were saved, the loss of the ship was a military scandal. She had escaped the Japanese during the worst part of the war in the Pacific, only to be lost because of a series of disastrous American mistakes.The master of the Coolidge, Henry Nelson, claimed he hadn’t been warned that the harbor was mined. Worse, in terms of wartime security, neither of the two US destroyers the Coolidge had encountered had challenged her. Nor had they relayed the vital information about the mines. “The first warning was from a signal station further in the harbor telling me to stop, that we were approaching danger,” he wrote.‘I, in turn, stopped the engines and backed the engines, but with the speed we were moving, we still went too far and we struck two mines. I immediately, with the speed we had left, headed the ship to the beach, and ordered “abandon ship ”, which was done and completed in 45 minutes.’‘No one mentioned to me, no one informed me, that there was a mine field in Espiritu Santo. Had there been some knowledge of mines, I never would have approached anywhere visible.’Captain Nelson was exonerated(免罪) by a court of inquiry but those responsible did not escape blame. The port director’s office at Noumea and the inefficiency of an experienced commanding officer of a navy patrol(巡逻队) and pilot boat were blamed.Today, the Coolidge is one of the world’s best wreck dives. Much of her original luxury decoration remains, including The Lady, perhaps the most photographed underwater icon in the world. Military equipment she wastransporting can also still be seen.(Note: Answer the questions or complete the statements in NO MORE THAN TEN WORDS.)78. The ship was “pressed into service by the military” suggests that it was ______________.79. What caused the sinking of the ship?80. Why did the ship still hit the mines after the captain stopped the engines?81. Why was the sinking of this ship a “scandal”?第II卷（共47分）I.

早已到毕业考的备考环节，大家应当以如何的心态去学习呢？
最先，大家应当授课上课认真听讲，积极发言，不耍心眼，不违背课堂秩序，它是最关键的，写作期终环节应以如何的心态学习培训。

假如你确保自身是以12分的精神实质来上课的，你的上课品质就能获得确保。

一样，积极发言也很重要，在课上要积极地和老师映衬，不可以坐着坐位上跟一个观众们一样，那般，教师就不清楚你到底学没学好，中小学六年级作文《作文期末阶段应以怎样的态度学习》。

然后，便是工作的难题。

课堂的作业要在课堂上进行，不必当做课外作业。

常言道：“今日事，今日毕。

”课外作业要保证保证质量，要用心、准时进行。

尽可能要单独进行，确实不容易再去问他人。

假如那样，你的课外作业才可以具有训练的实际效果。

最终，便是下课了的难题了。

下课时，要把没做完的工作做完了再与同学们讲话。

次之，工作做完后，尽可能能保证备考以前课的专业知识、课前预习一二节课的內容，那样你也就会带上难题去授课，品质会高些。

我坚信，假如你按之上的做法去学习，你的考试成绩一定会遥遥领先！。

期终评语

易广云期终评语易广云：你是一个很强的人，不仅学习强，身体也很强。

上课积极回答问题，参与课堂活动，为人诚实，开朗。

相比开学，言行举止更加文明了，与同学说话更有耐心了。

同时作为组长，更加团结每位组员，有团队意识。

不过，你的体力不如你的身体强，平时还是要多跑跑步。

与同学开玩笑时，说话可以更有艺术些，少肢体上的接触就更好了。

2011年下期期终评语易广云：你是一个在学习上你是位肯下工夫，上课也很认真听讲的同学。

作为组长，你乐意为了“养根轩”而尽心尽力，同时也想积极带好团队。

同时，你总是精力充沛，课堂上是活力四射，回答问题的声音不绝于耳。

并且能够带动一部分同学都会跟着你来。

这样很好，如果能够带来很好的影响的话希望你能在下个学期多发挥一些积极作用，减少一丝丝“噪音”就会更加有好的影响力。

2012年上期期终评语广云同学：在父母老师的监督配合下，你还是取得了不错的成绩。

课本剧表演你尽心尽力，秦始皇被你演出了另一番“气质”出来。

“玩”是一门“艺术”，它的真正价值、境界是在于日常学校工作为主、玩为辅，不影响自己日常中重要的事情完成。

过分沉溺于此会是玩物丧志。

本学期中，在你自己的努力下，在古代，“云”有祥和之寓意，希望你在班上的表现也能有祥“和”的特点。

2012年下期期终评语广云同学：很明显，在本学期期中之前，你对自己的学习降低了要求，玩心重了，所以你期中考试的成绩并没有取得你应该有的成绩。

亡羊补牢，犹未晚也。

进入生地复习和期末复习，你在学习态度端正了许多，学习也努力了许多，希望你从此以后，能够学习刻苦，收起玩心，以你的水平，长郡本部一定会是你的高中学校！定高目标，取高成就！2013年上期期终评语02易广云：进入初三以来，你发生了很大的转变，有了长远的进步。

在学习上变得认真、主动，改正了喜欢玩的缺点，在课堂方面，做了纪律委员后，对课堂做出一定的榜样带头作用，并维护了课堂纪律，希望你继续保持，老师期待你更大的进步！2013年下期期终评语。

When we see a powerful work of art, you feel it 21._______ deep within your core, giving us the power to make real-life changes.It has the power to educate people about almost anything. It creates awareness and 22._______information in a way that could be absorbed by many 23._______. In a world where there are those who don’t even have access to good education; art makes education an even greater equalizer of society.It breaks cultural, social, and economic barriers. While art hardly really solves poverty or 24._______ social justice on its own, it can be used as a leveled playing field for discourse and expression. The reason why everyone can relate to art is that everyone has emotions and personal experiences. Therefore, anyone can learn to appreciate art regardless of their social background, economic 25._______, or political affiliation.It 26._______ higher orders of thinking. Art doesn’t just make you absorb information. Rather, it makes you think about current ideas and inspire you to make your own. This is why creativity is a form of intelligence – it is a special ability that unlocks the 27._______ of the human mind. In fact, studies have shown that 28._______ to art can make you better in other fields of knowledge.The truth is that people have recognized how powerful art can be. Many times in history have we heard of people being criticized, threatened, censored, and even killed because of their artwork. Those 29._______ for these reactions, may it be an aggressive government or a dissident group, take these measures against artists knowing how much their works can affect the politics in a 30._______ area. In the hands of good people, however, art can be used to give back hope or instill courage in a society that’s undergoing a lot of hardshipsII. Reading Comprehension (1*15 + 2*16 = 47分)Section ADirections:For each blank in the following passage there are four words or phrases marked A, B, C and D. Fill in each blank with the word or phrase that best fits the context.Children are introduced to the arts in many different ways. Participation in the arts improves personal confidence, problem solving skills, and even memorization and social skills. As young brains develop, it is vital that the creative side of the brain receive equal attention to the __31__ side of the brain to ensure maximum education. Unfortunately, there are those who believe creativity holds little or no value. However, they could never be farther from the __32__.According to a National Education Association research report, “Teenagers and young adults of low socioeconomic status（SES）, who have a __33__of in-depth arts involvement, show better academic outcomes than low-SES youth with less arts involvement.” This research report shows that the arts strengthen the academic hemisphere of the brain. According to recent studies, as the brain focuses on math problems or reading, only certain areas of their brain are __34__. However, when teenagers and young adults are listening to music, drawing a picture or engaging the mind __35__, multiple areas of the brain are working at the same time. __36__, more areas of the brain are strengthened, resulting in stronger overall brain activity.With all the benefits of arts education, it is __37__ that some educational boards still believe sufficient education can be reached without the benefits of the arts. In January 2017, the Utah State Board of Education__38__an official command that added two classes to the school curriculum, requiring all students between sixth and eighth grades to take those courses. This __39__ limited the opportunity for the students to take elective arts courses.

For each of them there are four choices marked A, B, C and D. Choose the one that fits best according to the information given in the passage you have just read.(A)Nancy Meherne lives a simple life by the sea, gardening and surfing at Scarborough Beach just a walking distance from her house. The 92-year-old’s board was made in New Zealand in the 1970s. Unlike its owner, it’s a little seriously worn out (its blue and red pattern is long gone)—but it’ s easy to carry and suits her just fine. Often wearing just a swimsuit, despite summer water temperatures ranging from 14℃ to 18℃, the grandmother of seven walks to waist-deep water, waits for the perfect wave and jumps on.Born in Wellington in 1929 at the beginning of the Great Depression, Meherne says her life has been full of interesting or exciting moments. In her early 20s, after training and working as a schoolteacher, she left New Zealand by ship to study and work in England and other countries in Europe, spending her weekends and holidays exploring the region, taking free rides, sleeping on train platforms and staying in youth hotels.Her travels also took her to India, Afghanistan, Syria, Lebanon and Pakistan where she taught at a school for three months. After returning to New Zealand, Meherne raised three children with her husband, Doug, while teaching in primary schools. Her teaching philosophy was similar to her life philosophy, “You’ve got to have fun.”She remembers seeing the ocean for the first time and being shocked at its grandness. A keenswimmer and surf life saver in her youth, Meherne says she didn’t take up surfing until her late 30s or early 40s when she was living in Sumner and started borrowing her son’s board. “I never did try and stand up, but I loved it. I’d go whenever I could.”Meherne will be 93 in August, 2022 and says she will keep surfing for as long as she is able to “do a little jump” to get on the waves. Her husband Doug says, “She has certainly kept the bar pretty high there. She has aged but she hasn’t got old—you know what I’m saying?”46. We can learn from the first paragraph that ___________.A. Meherne surfs near her homeB. Meherne started surfing in the late 1970sC. Meherne’s worn board is too old to be usedD. summer water temperatures are unbearable for Meherne47. Which of the following words can best describe Meherne’s early life?A. Aimless and relaxingB. Hard and challenging.C. Busy and pitiful.D. Full and adventurous.48. What does Meherne’s husband Doug mean by saying the words in the last paragraph?A. Meherne has kept pushing and now reached her limit.B. Despite her growing age, Meherne is still quite energetic.C. Considering her growing age, Meherne is no longer fit for surfing.D. Meherne has set so high a standard that other surfers can never reach.49. Based on the information in the passage, which statement is true?A. Students graduated in May 2021 should line up at Grad Plaza and walk to the check-in area.B. Children under 5 can’t access the Stadium unless accompanied by an adult with a valid ID.C. Invited guests can print their registered tickets for scanning at the entrance of the Stadium.D. It’s advised that all attendees should wear a mask during the ceremony and not remove it.50. According to the passage, who can successfully pass the bag check security screening?A. Alex who wants to take group photos using an extendable hand-held selfie stick.B. Brandon who’s rushing to the Stadium right from JFK airport with a carry-on baggage.C. Christina’s father who brings a 24 oz. metal bottle of homemade champagne to celebrate.D. Dana’s grandmother who has a seizure disorder and is accompanied by her seizure alert dog.51. If a graduate’s parents live in Penn Station area, how can they get to the Stadium cost-effectively?A. Take the 7 train from Grand Central Terminal to the Mets-Willets Point station.B. Take the LIRR from Penn Station and all the way to Mets-Willets Point station.C. Take the New Jersey Transit from Penn Station and get off at Mets-Willets Point station.D. Take the LIRR to 61st Street-Woodside Station and get a taxi to the Mets-Willets Pointstation.(C)The medieval artists didn't know about perspective; they didn't want to make their people look like real, individual people in a real, individual scene. They wanted to show the truth, the eternal quality of their religious stories. So these artists didn't need to know about perspective.In the European Renaissance period, artists wanted to show the importance of the individual person and his or her possessions and surroundings. A flat medieval style couldn’t show this level of reality and the artists needed a new technique. It was the Italian artist Brunelleschi who discovered the technique of perspective drawing. At first the artists of the Renaissance only had single-point perspective. Later they realized that they could have two-pointed perspective and still later multi-point perspective.With two-point perspective they could turn an object (like a building) at an angle to the picture and draw two sides of it. The technique of perspective which seems so natural to us now is an invented technique, a part of the “Grammar of painting”. Like all bits of grammar there are exceptions about perspective. For example, only vertical and horizontal surfaces seem to meet on eye level. Sloping roof tops do n’t meet on eye level.For 500 years, artists in Europe made use of perspective drawing in their pictures. Nevertheless, there are a range of priorities that artists give in displaying individual styles. Crivelli wanted to show depth in his picture and he used a simple single-point perspective. Cezanne always talked about space and volume. Van Gogh, like some of the other painters of the Impressionist period, was interested in Japanese prints. And Japanese artists until this century were always very strong designers of “flat” pictures. Picasso certainly made pictures which have volume and depth. However, he wanted to keep our eyes on the surface and to remind us that his paintings are paintings and not illusions.It is technically easy to give an illusion of depth. However, a strong two dimensional design is just as important as a feeling of depth, and perhaps more important.52. According to the passage, which is the main concern for medieval artists?A. the individual person and his/her possessions and surroundingsB. real people, real scenesC. eternal timeless truth of the earthD. themes of religious stories53. The discovery of perspective was the result of ____________.A. Renaissance artists’ desire to prove that the medieval artists could show level of realityB. the need to turn an object at an angle and draw more than one side of itC. the subject being shifted from religious stories to individual person and surroundings.D. natural evolution of human senses54. The word “Grammar ” in paragrap h 3 is closest in meaning to ___________.A. constructionB. grammatical rulesC. rules and regulationsD. tones and volume55. The following artists’ priorities in style shift away from perspective except____________.A. CrivelliB. CezanneC. Japanese artistsD. Brunelleschi56. It can be inferred from the passage that Renaissance artists ______________.A. embraced the medieval style of eternal truthB. needed to develop a new approach towards painting to show a new level of realityC. were inspired by vertical and horizontal surfaces in inventing the technique of perspectiveD. saw two dimensional design more important than a feeling of depth57. The passage mainly discusses_______________.A. the difference between medieval and Renaissance artB. how the technique of perspective influenced the modern artC. the discovery of the technique of perspectiveD. the contribution of Renaissance artistsSection CDirections: Complete the following passage by using the sentences given below. Each sentence can be used only once. Note that there are TWO MORE sentences than you need.Food Might Still Be Okay Longer Than You ThinkMany products often come with expiration dates to indicate a predetermined shelf life, like food and medicine. Once the indicated date has passed, these products are generally deemed unfit for use or consumption— 58. _____________________According to the U.S. Environmental Protection Agency, the average person generated about 2.68 pounds of municipal solid waste per day in the 1960s, which include food, plastic, and paper waste. This amount increased to 4.74 pounds in the 2000s, finally reaching 4.9 pounds in 2018. The disposal of expired but usable or consumable goods can contribute to overall waste. By minimizingthis, an individual may be able to reduce the amount of waste they produce.Here’s what expiration dates generally mean for various products and when consumers can safely overlook them. For most products, the date on the packaging label is not an expiration date, but a ‘best by’ or ‘sell by’ date, says Londa Nwadike, extension associate professor of food safety at the Kansas State University and the University of Missouri. 59. _____________________ Although expired food may not be at its peak deliciousness, it should still be safe to consume.60. _____________________ If a product is discolored, moldy, abnormally soft, or it generally looks and/or smells bad, throw it out immediately—no matter how carefully it was stored.61. _____________________ Perishable foods should be kept in the refrigerator or the freezer to avoid spoilage. Foods that do not require refrigeration for safety have lower risk and they can generally be consumed safely longer, she adds. For instance, dry pasta can still be eaten one year after opening it if it was stored in the pantry.III.

3、相同的相互结合的孔和轴之间的关系称为配合。

4、国家标准规定将螺纹的旋合长度分为三组，即、和。

5、孔轴配合时，如果ES= ei ，那么此配合是配合；如果ES=es ，那么此配合是配合；如果EI=es ，那么此配合是配合。

6、尺寸公差是尺寸的允许，因此公差值前不能有。

7、孔的上极限偏差用表示，轴的下极限偏差用表示。

8、螺纹与组成螺纹精度等级，分为、和三级。

9、一零件尺寸为φ90j7（020.0015.0+-），其上极限偏差为 μm,尺寸公差为 mm10、螺距误差包括两部分，即与旋合长度有关的和与旋合长度无关的。

从互换性角度看，螺距的是主要的。

11、根据形成间隙或过盈的情况，配合分为、和三类。

12、代表过渡配合松紧程度的特征值是和。

13、通端螺纹量规检验螺纹的，止端螺纹量规控制螺纹的。

14、螺纹公差带是公差带，以基本牙型的轮廓为。

公差带由其相对于基本牙型的因素和因素组成。

15、配合公差是允许或的变动量，它等于组成配合的和之和。

配合公差越大，则配合的程度越大。

16、孔的公差带在轴的公差带之时为间隙配合，孔与的轴的公差带相互时为过渡配合，孔的公差带在轴的公差带之时为过盈配合。

二、判断题（20分）1、普通螺纹一般以螺纹的顶径作为其公称直径（）2、具有互换性的零件应该是形状和尺寸完全相同的零件。

（）3、螺纹升角是指在中径圆柱上，螺旋线的切线与垂直于螺纹轴线的平面的夹角（）4、某一零件的实际（组成）要素正好等于其公称尺寸，则该尺寸必然合格。
