SAT数学试题及答案x

SAT数学试题及答案x

SAT数学试题及答案x1. 题目:一个矩形的长是宽的两倍,如果矩形的面积是48平方单位,那么矩形的宽是多少?答案:设矩形的宽为 \( w \) ,则长为 \( 2w \) 。

根据面积公式 \( \text{面积} = \text{长} \times \text{宽} \) ,我们有\( 2w \times w = 48 \) 。

解这个方程得到 \( w^2 = 24 \) ,所以\( w = \sqrt{24} = 2\sqrt{6} \) 。

因此,矩形的宽是\( 2\sqrt{6} \) 单位。

2. 题目:一个圆的半径是5单位,求这个圆的周长。

答案:圆的周长公式是 \( C = 2\pi r \) ,其中 \( r \) 是半径。

将 \( r = 5 \) 代入公式,得到 \( C = 2\pi \times 5 =10\pi \) 。

所以,这个圆的周长是 \( 10\pi \) 单位。

3. 题目:如果一个数 \( x \) 的三倍加上5等于20,求 \( x \) 的值。

答案:根据题目,我们有方程 \( 3x + 5 = 20 \) 。

解这个方程,首先从两边减去5得到 \( 3x = 15 \) ,然后除以3得到 \( x = 5 \) 。

因此,\( x \) 的值是5。

4. 题目:一个三角形的底边长为8单位,高为6单位,求这个三角形的面积。

答案:三角形的面积公式是 \( \text{面积} = \frac{1}{2}\times \text{底} \times \text{高} \) 。

将底边长8单位和高6单位代入公式,得到 \( \text{面积} = \frac{1}{2} \times 8 \times 6 = 24 \) 。

所以,这个三角形的面积是24平方单位。

5. 题目:如果一个函数 \( f(x) \) 满足 \( f(x+2) = 2f(x) \) ,并且 \( f(1) = 3 \) ,求 \( f(5) \) 的值。

Answer the questions on the basis of what is stated or implied in the passages and in any introductory material that may be provided.Question 1-4 are based on the following passages.Passage 1The eighteenth-century botanist Carolus Linnaeus’enormous and essential contribution to natural history was to devise a system of classification whereby any plant or animal could identified andslotted into an overall plan. Yet Linnaeus himself would probably be the first to admit that classification is only a tool, and not the ultimate purpose, of biological inquiry. Unfortunately, this truth was not apparent to his immediate successors, who for the nest hundred years were to concern themselves almost exclusively with classification.Passage 2I am a heretic about Linnaeus. I do not dispute the value of the tool he gave natural science, but I am wary about the change it has effected on human relationship to the world. From Linnaeus on, much of science has been devoted to sorting masses into individual entities and arranging the entities neatly. The cost of having so successfully itemized and pigeonholed nature is to limit certain possibilities of seeing and apprehending. For example, the modern man thinks that he or she can best understand a tree (or a species of tree) by examining a single tree. But trees are not intended to grow in isolation. They are social creatures, and their society in turn supports other species of plants, insects, birds, mammals, and micro-organisms, all of which make up the whole experience of the woods.pared to the author of Passage 2, the author of Passage 1 regards Linnaeus with more(A)cynicism(B)bafflement(C)appreciation(D)nostalgia(E)resentment2.Unlike the author of Passage 1, the author of Passage 2 make use of(A) scientific data(B) literary allusion(C) historical research(D) personal voice(E) direct citation3.Both passages emphasize which of the following aspects of Linnaeus’ work(A)The extent to which it contributed to natural science(B)The way in which it limits present-day science(C)The degree to which it revived interest in biology.(D)The decisiveness with which it settled scientific disputes(E)The kinds of scientific discoveries on which it built.4.The author of Passage 1 would most likely respond to the opening of Passage 2 (Line 12-17) byarguing that the author of Passage 2 has(A)demonstrated that Linnaeus should be better known as a scientist that he currently is(B)minimized the achievements of those scientists who built on Linnaeus’ work(C)refused to appreciate the importance of proper classification to scientific progress(D)failed to distinguish the ideas of Linnaeus from those of his followers(E)misunderstood Linnaeus’ primary contribution to natural historyQuestion 5-10 are based on the following passage.The following is an excerpt from a translation of a novel written in Spanish by an author from Colombia. In a fanciful manner, the novelist portrays the townspeople of an isolated village.Dazzled by so many and such marvelous inventions, the people of Macondo did not know where their amazement began, They stayed up all night looking at the electric bulbs fed by the electric plant that Aureliano Triste had brought back when the train made its second trip, and it took time and effort for them to grow accustomed to its obsessive noise.They became indignant over the living images that the prosperous merchant Bruno Crespi projected on the screen in the theatre with the lion-head ticket windows, for the character who had died and was buried in one film, and for whose misfortune tears of affliction had been shed, would reappear alive and transformed into an Arab sheik in the next one. The audience, who paid tow cents apiece to share the difficulties of the actors, would not tolerate such an outlandish fraud and they broke up the seats. The major, at the urging of Bruno Crespi, explained in a proclamation that the cinema was a machine of illusions that did not merit the emotional outbursts of the audience. With that discouraging explanation many felt that they had been the victims of some new trickery and theydecided not to return to the movies, considering that they already had too many troubles of their own to weep over the acted-out misfortunes of imaginary beings.Something similar happened with cylinder phonographs brought from France and intended as a substitute for the antiquated hand organs used by the band of musicians. For a time the phonograph records had serious effects on the livelihood of the musicians. At first curiosity increased the business on the street where they were sold and there was even word of respectable persons who disguised themselves as workers in order to observe the novelty of the phonograph at firsthand, but from so much and such close observation they soon reached the conclusion that it was not an enchanted mill as everyone had thought and as some had said, but a mechanical trick that could not be compared with something so moving, so human, and so full of everyday truth as a band of musicians, It was such a serious disappointment that when phonograph became so popular that there was one in every house they were not considered objects for amusement for adults but as something good for children to take part.On the other hand, when someone from the town had the opportunity to test the crude reality of the telephone installed in the railroad station, which was thought to be rudimentary version of the phonograph because of its crank, even the most incredulous were upset. It was as if God had decided to put to the test every capacity for surprise and was keeping the inhabitants of Macondo in a permanent alteration between excitement and disappointment, doubt and revelation, to such an extreme that no one knew for certain where the limits of reality lay.5.The word “obsessive” (line 5) most nearly means(A)enthusiastic(B)persistent(C)obvious(D)infatuated(E)hardworking6.The “fraud” (Line 11) that upset the citizens of Macondo was related to the(A)excessive charge for admission(B)outlandish adventures of the characters on the screen(C)fact that the events depicted on the screen did not actually occur(D)types of difficulties the actors faced(E)implausible plots of the stories that were told7.The citizens lost interest in their phonographs because(A)the machines lack the heart and soul of true musicians(B)few people were able to operate them(C)the machines were too difficult to observe firsthand(D)many musicians lost their job because of them(E)the children were breaking them faster than they were made8.The citizens of Macondo were distressed by the arrival of telephone because they(A)did not know where it come from(B)had expected a more socially beneficial invention(C)could envision the change it would bring to daily village life(D)no longer felt able to make the usual assumptions about their world(E)were fearful that it would have serious affects on their continued employment9.The aspects of the new inventions that most disappointed the citizens was that these inventions(A)were not all fashioned with crank(B)did not have any real educational value(C)were not at all what they seemed to be(D)were meant purely for entertainment(E)were so intricate they ere difficult to operate10.The major purpose of the passage is to(A)illustrate the influence the distinguished residents of Macondo had on the other citizens(B)describe the new scientific inventions that were introduced to Macondo(C)depict a diverse crowd reacting in unison to a magical performance(D)describe the people’s responses to the influx of technical advances(E)delineate old-fashioned ideas about the virtue of nature over technologyQuestions 11-15 are based on the following passage.This passage is from the preface to a 1997 book by a United States journalist detailing a disagreement between doctors and family members about a child’s medical treatment at a hospital in California.Under my desk I keep a large carton of cassette tapes. Though they have all been transcribed, I still like to listen to them from time to time.Some are quiet and easily understood. They are filled with the voices of American doctors, interrupted occasionally by the clink of a coffee cup or beep of a pager. The rest—more than halfof them—are very noisy. They are filled with the voices of the Lees family, Hmong refugees from Laos who came to the United States in 1980. Against a background of babies crying, children playing, doors slamming, dishes clattering, a television yammering, and an air conditioner wheezing, I can hear the mother’s voice, by turns breathy, nasal, gargly, or humlike as it slides up and down the Hmong language’s eight tones; the father’s voice, louder, slower, more vehement; and my interpreter’s voice, mediating in Hmong and English, low and deferential ineach. The hubbub summons sense-memories: the coolness of the red metal folding chair, reserved for guests, that was always set up when I arrived in the apartment; the shadows cast by the amulet that hung from the ceiling and swung inthe breeze on its length of grocer’s twine; the tastes of Hmong food.I sat on the Lees’ red chair for the first time on May 19, 1988. Earlier that spring I hadcome to Merced, California, because I had heard that there were somemisunderstandings at the county hospital between its Hmong patients and medical staff. One doctor called them“collisions,” which made it sound as if two different kinds of people had rammed into each other, head on, to the accompaniment of squealing brakes and breaking glass. As it turned out, the encounters were messy but rarely frontal. Both sides were wounded, but neither side seemed to know what had hit it or how to avoid another crash.I have always felt that the action most worth watching occurs not at the center of things but where edges meet. I like shorelines, weather fronts, international borders.These places have interesting frictions and incongruities, and often, if you stand at the point oftangency, you can see both sides better than if you were in the middle of either one. This is especially true when the apposition is cultural. When I first came to Merced, I hoped that the culture of American medicine, about which I knew a little, and the culture of the Hmong, about which I knew nothing, would somehow illuminate each other if I could position myself between the two and manage not to get caught in the crossfire. But after getting to know the Lees family and theirdaughter’s doctors and realizing how hard it was to blame anyone, I stopped analyzing thesituation in such linear terms. Now, when I play the tapes late at night, I imagine what they would sound like if I could splice them together, so the voices of the Hmong and those of the American doctors could be heard on a single tape, speaking a common language.11. In line 12, “summons” most nearly means(A) sends for(B) calls forth(C) requests(D) orders(E) convenes12. It can be inferred from lines the last five lines in the third paragraph that “collisions”wasNOT an apt description because the(A) clash between Hmong patients and medical staff was indirect and baffling(B) Hmong patients and the medical staff were not significantly affected by the encounters(C) medical staff was not responsible for the dissatisfaction of the Hmong patients(D) misunderstandings between the Hmong patients and the medical staff were easy to resolve(E) disagreement reached beyond particular individuals to the community at large13. Which of the following views of conflict is best supported by lines 26-28 (“These . . . one”)in the last paragraph(A) Efforts to prevent conflicts are not always successful.(B) Conflict can occur in many different guises.(C) In most conflicts, both parties are to blame.(D) You can understand two parties that have resolved their conflicts better than two parties thatare currently in conflict.(E) You can learn more about two parties in conflict as an observer than as an involved participant.14. According to lines 28-32 (“When I . . . crossfire”), the author’s initial goal was to(A) consider the perspectives of both the American doctors and the Lees family to see what insightsmight develop(B) serve as a counselor to the county hospital’s Hmong patients in order to ease their anxieties(C) work out a compromise between the Americandoctors and the Lees family(D) acquire a greater knowledge of how the Americanmedical culture serves patients(E) try to reduce the misunderstandings between the American doctors and the Lees family andpromote good will15. At the end of the passage, the author suggests that it would be ideal if the(A) differences between the Lees family and the American doctors could be resolved quickly(B) concerns and opinions of the Lees family and the American doctors could be merged(C) American doctors could take the time to learn more about their Hmong patients(D) Hmong patients could become more vocal indefense of their rights(E) Hmong patients could get medical treatment consistent with their cultural beliefsSAT答案Answers:ⅠSentence completion1-5 AACEA 6-10 ACBCA 11-15 EEDCAⅡImproving Sentences & Identifying Sentence Errors1-5 DEDBB 6-10 DEEEB 11-15 CBDEBⅢPassage-based reading1-5 CDADB 6-10 CADCD 11-15 BAEAB。

SAT试题——长篇阅读练习SAT Reading Comprehension Test 110 mins - 7 questionsThe extract is taken from a book written sixty years ago by a British scientist in which he considers the relationship between science and society.The pioneers of the teaching of science imagined that itsintroduction into education would remove the conventionality,artificiality, and backward-lookingness which were characteristic;of classical studies, but they were gravely disappointed. So, too, in5 their time had the humanists thought that the study of the classicalauthors in the original would banish at once the dull pedantry and superstition of mediaeval scholasticism. The professionalschoolmaster was a match for both of them, and has almostmanaged to make the understanding of chemical reactions as dull10 and as dogmatic an affair as the reading of Virgil's Aeneid.The chief claim for the use of science in education is that itteaches a child something about the actual universe in which he is living, in making him acquainted with the results of scientific15 discovery, and at the same time teaches him how to think logicallyand inductively by studying scientific method. A certain limitedsuccess has been reached in the first of these aims, but practically none at all in the second. Those privileged members of thecommunity who have been through a secondary or public school20 education may be expected to know something about theelementary physics and chemistry of a hundred years ago, but they probably know hardly more than any bright boy can pick up from an interest in wireless or scientific hobbies out of school hours.As to the learning of scientific method, the whole thing is palpably25 a farce. Actually, for the convenience of teachers and therequirements of the examination system, it is necessary that thepupils not only do not learn scientific method but learn precisely the reverse, that is, to believe exactly what they are told and toreproduce it when asked, whether it seems nonsense to them or30 not. The way in which educated people respond to such quackeriesas spiritualism or astrology, not to say more dangerous ones such as racial theories or currency myths, shows that fifty years ofeducation in the method of science in Britain or Germany hasproduced no visible effect whatever. The only way of learning the35 method of science is the long and bitter way of personalexperience, and, until the educational or social systems are altered to make this possible, the best we can expect is the production of aminority of people who are able to acquire some of the techniques of science and a still smaller minority who are able to use and40 develop them.1. The author implies that the 'professional schoolmaster' (line 7) hasA. no interest in teaching scienceB. thwarted attempts to enliven educationC. aided true learningD. supported the humanistsE. been a pioneer in both science and humanities.2. The author’s attitude to secondary and public school education in the sciences isA. ambivalentB. neutralC. supportiveD. satiricalE. contemptuous3. The word ‘palpably’(line 24) most nearly meansA. empiricallyB. obviouslyC. tentativelyD. markedlyE. ridiculously4. The author blames all of the following for the failure to impart scientific method through the education system exceptA. poor teachingB. examination methodsC. lack of direct experienceD. the social and education systemsE. lack of interest on the part of students5. If the author were to study current education in science to see how things have changed since he wrote the piece, he would probably be most interested in the answer to which of the following questions?A. Do students know more about the world about them?B. Do students spend more time in laboratories?C. Can students apply their knowledge logically?D. Have textbooks improved?E. Do they respect their teachers?6. Astrology (line 31) is mentioned as an example ofA. a science that needs to be better understoodB. a belief which no educated people holdC. something unsupportable to those who have absorbed the methods of scienceD. the gravest danger to societyE. an acknowledged failure of science7. All of the following can be inferred from the text exceptA. at the time of writing, not all children received a secondary school educationB. the author finds chemical reactions interestingC. science teaching has imparted some knowledge of facts to some childrenD. the author believes that many teachers are authoritarianE. it is relatively easy to learn scientific method.SAT阅读:Reading Comprehension Test 1参考答案1.Correct Answer: BExplanation:When we look back to line 7, we read, "The professional schoolmaster was a match for both of them, and has almost managed to make the understanding of chemical reactions as dull and as dogmatic an affair as the reading of Virgil's Aeneid."This tells us that the schoolmaster has made learning dull. And so we eliminate answers C and E which imply he has done something good.But to be sure of the answer we should also read the previous sentences. We learn that, "The pioneers of the teaching of science imagined that its introduction into education would remove the conventionality, artificiality, and backward-lookingness which were characteristic of classical studies......" This section tells us that otherpeople tried to alter the nature of education, but the "professional schoolmaster was a match for both of them". He therefore prevented (thwarted) these attempts, and the answer is B.2.Correct Answer: EExplanation:To find the attitude, try asking yourself whether the author is positive, negative or neutral to the subject. Then look for the evidence. Here, it is obvious that he thinks that nothing very valuable is learned in school about science and scientific method. He is therefore negative. Eliminate the neutral (A and B) words, and the positive (C), and then decide between D and E. He seems to be expressing contempt rather than mocking. And so E is the best choice.3.Correct Answer: BExplanation:Go back to the text and find a word of your own to replace‘palpably’before you even look at the choices. We read, "As to the learning of scientific method, the whole thing is palpably a farce." Here, I could substitute ‘obviously’or ‘clearly’. As it happens, one of the words is there in the choices. (B). If it had not been there, there would have been something sufficiently similar to make a choice.4.Correct Answer: EExplanation:Be careful on ‘except’questions. You are looking for something the author does not do.He does blame poor teaching, (lines 7-10), exams (line 26), social and education systems (line 36), lack of direct experience (lines 34-38), but he never blames the students. Hence answer E.5.Correct Answer: CExplanation:This is an ‘inference’question. We need to find out what the author’s main complaint is. This concern of the author will tells us what he would like to see. From lines 11 to 18 in particular we learn that he is especially interested in whether a student can apply his or her knowledge. So, we conclude that answer C is best.6.Correct Answer: CExplanation:Astrology is mentioned as a ‘quackery’. Quackery is something that claims to be true but is actually based on falsity. He implies that people are fooled by astrology, but he also implies that there are other more ‘dangerous’ideas. So we eliminate A, B and D. It is not likely that astrology is a ‘failure of science’, but it is something that scientists would not approve of. Hence answer C.7.Correct Answer: EExplanation:This is an ‘except’question. Be careful! You are looking for something that cannot be inferred from the text. We can find evidence that the author finds reactions interesting (line 9), and that children have learnt some facts (beginning of the second paragraph), and that he thinks teachers are strict (line 10 and part of paragraph 2). We can also infer from the use of the phrase ‘privileged members’(line 18) that he believes that not all received secondary education. But we find that he thinks it is hard to learn scientific method- ‘The only way of learning the method of science is the long and bitter way of personal experience". And so we choose E.。
