Passage Two Many objects in daily use have clearly been influenced by science. However, their form and function, their dimensions and appearance, were determined by technologists, designers, inventors, and engineers using nonscientific modes of thought. Many features and qualities of the objects that a technologist thinks about cannot be reduced to unambiguous verbal descriptions; they are dealt with in the mind by a visual, nonverbal process, pyramids, cathedrals, and rockets exist not because of geometry or thermos-dynamics (热动力学), because they were first the picture in the minds of those. The creative shaping process of a technologist’s mind can be seen in nearly every artifact that exists. For example, in designing a diesel engine, a technologist might express individual ways of nonverbal thinking on the machine by continually using an intuitive sense of rightness and fitness. What would be the shape of the combustion chamber Where should the valves be placed Would it have a long or short piston Such questions have a range of answers that are supplied by experience, by physical requirement, by limitations of available space, and not in the least by a sense of form. Some decisions, such as wall thickness and pin diameter, may depend on scientific calculations, but the nonscientific component design remains primary. Design courses, then should be an essential element of engineering curricula. Nonverbal thinking, a central mechanism in engineering design, involves perceptions, which is the special technique of the artists, not the scientist. Because perceptive processes are not assumed to need "hard thinking", nonverbal thought is sometimes seen as a primitive stage in the development of cognitive processes and inferior to verbal mathematical thought. If courses in design, which in a strongly analytical engineering curriculum provide the background required for practical problem-solving, are not provided, we can expect to encounter silly but costly errors occurring in advanced engineering systems. For example, early modes of high-speed railroad cars loaded with sophisticated controls were unable to operate in a snowstorm because the fan sucked snow into the electrical system. Absurd random failures that plague automatic control systems are a reflection of the chaos that results when design is assumed to be primarily a problem in mathematics. In the passage, what is the writer primarily concerned with
已知数据文件IN14.DAT中存有300个四位数,并已调用读函数readDat()把这些数存入数组a中。请编制一个函数jsValue(),其功能是:求出所有这些四位数是素数的个数cnt,再把所有满足此条件的四位数依次存入数组b中,然后对数组b中的四位数按从小到大的顺序进行排序,最后调用写函数writeDat()把结果输出到OUT14.DAT文件。 例如:5591是素数,则该数满足条件存入数组b中,且个数cnt=cnt+1。 9812是非素数,则该数不满足条件,忽略。 注意:部分源程序已给出。程序中已定义数组:a[300]、b[300];已定义变量:cnt。请勿改动主函数main()、读函数 readDat()和写函数writeDat()的内容。 [试题程序] #include<stdio.h> int a[300],b[300],cnt=0; int isP(int m) int i; for(i=2;i<m;i++) if(m%i==0)return 0; return 1; void jsValue() main() int i; readDat(); jsValue(); writeDat(); for(i=0;i<cnt;i++)printf("b[%d]=%d\n",i,b[i]); readDat() FILE *fp; int i; fp=fopen("IN14.DAT","r"); for(i=0;i<300;i++)fscanf(fp,"%d,",&a[i]); fclose(fp); writeDat() FILE *fp; int i; fp=fopen("OUT14.DAT","w"); fprintf(fp,"%d\n",cnt); for(i=0;i<cnt;i++)fprintf(fp,"%d\n",b[i]); fclose(fp);

TEXT C We have to admire Suzanne Somers’s persistence. She doesn’t give up--even when virtually the entire medical community is lined up against her. Three years ago, Somers wrote a best-selling book called The Sexy Years in which she promoted so-called bioidentical hormones as a more natural alternative to hormones produced by drug companies for menopausal women. Somers, now 60, claimed that these individually prepared doses of estrogen and other hormones, sold via the Internet or by compounding pharmacies, made her look and feel half her age. As the popularity of bioidenticals soared, major medical organizations like the American College of Obstetricians and Gynecologists grew so alarmed that they mounted publicity campaigns to convince Somers’s readers that these alternative treatments, which are usually custom made for each patient, haven’t been proven safe or more effective than traditional hormone therapy for symptoms like hot flashes. This month Somers is at it again with her latest book, Ageless. Subtitled The Naked Truth About Bioidentical Hormones, the cover features a coquettish shot of the actress unclothed from the collarbone up. Inside, she calls bioidenticals "the juice of youth" and also promotes the questionable dosage advice of a former actress and "independent researcher" named T.S.. Wiley who thinks menopausal women should have as much estrogen in their bodies as 20-year-olds. Now, even some of the pro-bioidentical doctors Somers quotes in her books are screaming foul. "Many of the claims throughout the book are scientifically unproven and dangerous," three of these doctors assert in a letter sent a few weeks ago to Somers’s publisher, Crown. Somers adamantly defends bet book and bioidenticals. "From a woman’s standpoint, this is the first time we’ve gotten some relief in a non-drug way," she says in an interview with NEWSWEEK. "Doctors are embarrassed that they don’t know about this," Somers says. "When doctors don’t have an answer, they like to pooh-pooh it." The word bioidentical is a marketing term, not a scientific one, and it means different things to different people. To most doctors, bioidentical refers to a wide variety of FDA-approved drugs that are virtually identical to the hormones produced by women’s ovaries. They come in many forms and doses, some of which have been used for years. Somers uses the term to refer to made-to-order treatments created by compounding pharmacies with dosages usually determined by the results of blood tests every two weeks (the method Somers herself uses), or regular saliva tests, a method most experts say is an unreliable way to measure a women’s specific hormone needs. Somers claims that she is so "in touch" with her body’s needs that she can "tweak" her hormones even without the benefit of these tests. Proponents of Somers’s program say only hormones prepared specifically for each woman can meet her unique needs. But since the Women’s Health Initiative, the FDA has approved many new hormone products, including some in very low doses. While the FDA process isn’t perfect, it’s certainly better than what consumers get with compounding products: no black box warning about side effects, no package insert, no data on relative safety, no check on advertising claims and no manufacturing oversight. Somers says these custom-made treatments are natural and not really drugs. That’s just not true. Bioidenticals may start out as wild yams or soybeans, but by the time this plant matter has been converted into hormone therapy, it is in fact a drug. All of these products--whether or not they’re approved by the FDA--are chemicals synthesized in a lab. Another thing you should know: there are only a few labs in the world that synthesize these hormones. Everyone--from small compounding pharmacies to big pharmaceutical companies gets their ingredients from the same places, Somers argues that bioidenticals are safer than FDA-approved hormones even though there are no high-quality studies to prove that assertion. In the absence of any reliable research to the contrary, most women’s health experts say it’s prudent to assume that all hormone products (FDA approved or not) carry the same heart disease and cancer risks. Which of the following statements is TRUE about some doctors Somers quotes in her books
A. Some doctors turn to support Somers’s bioidenticals.
B. Some doctors were in favor of Somers’s bioidenticals.
C. Suzanne Somers’s new book has some doctors crying good.
D. Some doctors wrote a letter to the magazine named Crown.
