Unit 4 Fun, Oh, Boy, Fun, You Could Die from it.
Key to the Exercises
Text comprehension
I. Decide which of the following best states the author's view on fun.
C
II. Judge, according to the text, whether the following statements are true or false.
1. T (Refer to Paragraphs 5 to 10.)
2. T (Refer to Paragraph 7.)
3. F (Refer to Paragraphs 11 and 12. Big occasions like Christmas, wedding days, and honeymoons are supposed to be fun; however, they are not necessarily occasions of fun as the author points out in Paragraph 12 that "not much is (fun).")
4. T (The statement suggests that fun does not only come from playing or enjoying oneself on weekends but also from working and the fulfillment of one's duty during weekdays.)
5. F (When saying that those days made her really regretful that she had to grow up, Jordan is not lamenting over the passage of the innocent childhood days. Instead, with this example, she aims to elucidate the essence of fun.)
III. Answer the following questions.
1. Refer to Paragraphs 2 and 5. Most people believe that fun is and should be readily available whenever they want it. If there isn't fun, they would make fun, or if something is not fun, they would make it fun. In a word, they deserve fun which is within their reach.
2. Refer to Paragraph 10. Advertisements, or TV commercials, help to develop the modern fun fetish by setting examples and showing how much fun we should have got from consuming all the items being advertised.
3. Refer to Paragraph 1
4. Jordan was twelve when she, as she remembers, had an especially wonderful time. She had a fun night to look forward to that day and she had lots of candies and her friend kept imitating a sailor's posture and words. All these were simple forms of fun yet appealing to a girl of twelve. More importantly, she was a simple, innocent girl without a dulled and insatiable appetite for fun; that is why she could feel the fun of simple joys.
4. The author employs the technique of negation -- i.e. defining a term through showing what it is not -- in defining the concept of fun. Fun, according to Jordan, is not a family visit to Disney World; neither is it celebrating big occasions. Fun
is in simple pleasures of life which lie rather in one's work and the fulfillment of one's duty.
5. An open question; answers may vary.
IV. Explain in your own words the following sentences.
1. Nowadays, people believe that they can have fun whenever they want it, and that they should have fun; otherwise they would be leading a dull and bitter life as a puritan.
2. We have long assumed that fun was easy to have, but now we are paying a price for that shallow-mindedness, i.e., our party is hardly as much fun as it is expected to be.
Structural analysis of the text
Paragraph 12 is the turning point where the writer switches from negation to affirmation. With the last three paragraphs presented mostly affirmatively, the tone is thus turned from irony to matter-of-factness.
Rhetorical features of the text
Here is another example: "Think of all the things that got the reputation of being fun. Family outings were supposed to be fun. Sex was supposed to be fun. Education was supposed to be fun. Work was supposed to be fun. Walt Disney was supposed to be fun. Church was supposed to be fun. Staying fit was supposed to be fun." (Paragraph 6) The underlined part in the quotation displays the repetition of the pattern: "?was supposed to be fun," which shows, by way of illustration, how one might spare no effort to find fun in everything.

请编一个函数fun，它的功能是：根据以下公式求π的值(要求满足精度0.0005，即，某项小于0.0005时停止迭代)： 程序运行后，如果输入精度0.0005，则程序输出多少。 注意：部分源程序存在PROG1.C中，请勿改动主函数和其他函数中的内容，仅在函数fun的指定的部位填入你编写的若干语句。 试题源程序如下： #include ＜stdio.h＞ #include ＜math.h＞ double fun(double eps) { } main() { double x; printf("Input eps:"); scanf("%lf",&x); printf("\neps=%lf, PI=%lf\n",x,fun(x)); } 分析： (1)本题所用基本算法应为累加。假设累加值放在变量s中，累加项放在变量t中，累加操作由语句s=s+t;来实现。 (2)若称为第1累加项，则其前的1为第0累加项，其后的一项为第2累加项，按给定的公式可知，从第1累加项开始，后一项的累加项是前一项的值乘以。所以当前的累加项应当是：t=t*n/(2.0*n+1.0)。表达式右边的t中是前一项的值，表达式左边的t为当前的每累加累加项。请注意，不要写成：t*n/(2*n+1)而进行整除。 (3)若第0累加项的1作为s的初值，语句：s=s+t;执行n次，就把第1到第n项累加到了s中。每进行一次累加，n值增1。 (4)把以上操作放在循环中。按本题规定，当某项小于eps(0.0005)时停止迭代，因此若用while循环，可用t＞=eps作为控制循环进行的条件：while( t＞=eps ){ s+=t; n++; t=t*n/(2.0*n+1); } (5)注意应给所用变量赋适当的初值。 (6)退出循环后，函数的返回值应是：2*s。 请编一个函数fun，其中n所指存储单元中存放了数组中元素的个数。函数的功能是：删除所有值为y的元素。已在主函数中给数组元素赋值，y的值由主函数通过键盘读入。 注意：部分源程序存在PROG1.C中，请勿改动主函数和其他函数中的内容，仅在函数fun的指定的部位填入你编写的若干语句。 试题源程序如下： #include ＜stdio.h＞ #define M 20 void fun(int bb[],int *n, int y) { }
试题1 请编写一个函数fun，它的功能是：将两个两位数的正整数a、b合并形成一个整数放在c中。合并的方式是：将a数的十位和个位数依次放在c 数的千位和十位上，b数的十位和个位数分别放在c数的个位和百位上。例如；当a＝45，b＝12，调用该函数后c＝4251。函数形式void fun(int a,int b,long *c)。并写主函数验证，a,b两数从键盘输入。 #include 第01套给定程序中函数fun的功能是将形参n所指变量中各位上为偶数的数去除剩余的数按原来从高位到低位的顺序组成一个新的数并通过形参指针n传回所指变量。例如输入一个数27638496新的数为739。请在程序的下划线处填入正确的内容并把下划线删除使程序得出正确的结果。注意源程序存放在考生文件夹下的BLANK1.C中。不得增行或删行也不得更改程序的结构给定源程序include ltstdio.hgt void fununsigned long n unsigned long x0 i int t i1 whilen tn __1__ ift2 __2__ xxti ii10 n n /10 n__3__ main unsigned long n-1 whilengt99999999nlt0 printfquotPlease input0ltnlt100000000: quot scanfquotldquotampn funampn printfquotnThe result is: ldnquotn 解题思路第一处t是通过取模的方式来得到n的个位数字所以应填10。第二处判断是否是奇数所以应填0。第三处最后通形参n来返回新数x 所以应填x。给定程序MODI1.C中函数fun 的功能是计算n。例如给n输入5则输出120.000000。请改正程序中的错误使程序能输出正确的结果。注意不要改动main函数不得增行或删行也不得更改程序的结构给定源程序include ltstdio.hgt double fun int n double result 1.0 if n 0 return 1.0 while n gt1 ampamp n lt 170 result n-- return result main int n printfquotInput N:quot scanfquotdquot ampn printfquotnnd lfnnquot n funn 解题思路第一处条件语句书写格式错误应 版本：matlab 2010a Matlab datafun函数的相关用法 目录： 1.conv2 (2) 2.conv (3) 3.convn (4) 4.corrcoef (4) 5. cov (5) 6. cumprod (6) 7. cumsu (7) 8. deconv (7) 9. detrend (8) 10. diff (9) 11. fft2 (9) 12. fft (11) 13.fftshift (12) 14. filter2 (12) 15. filter (13) 16. hist (13) 17. histc (14) 18. ifft2 (16) 19. issorted (17) 20. max (19) 21. mean (20) 22. median (20) 23. min (21) 24. mode (22) 25. prod (23) 26. sort (24) 27. sortrows (26) 28. std (27) 29. sum (28) 30. var (30) 1.conv2 功能简介 进行二维卷积操作 使用方法 C=conv2(A,B) C=conv2(Hcol,Hrow,A) C=conv2(...,'shape') 说明：对于 C=conv2(A,B) ，conv2 的算矩阵 A 和 B 的卷积，若 [Ma,Na]＝size(A), [Mb,Nb]=size(B), 则size(C)=[Ma+Mb-1,Na+Nb-1]; C=conv2(Hcol,Hrow,A) 中，矩阵 A 分别与 Hcol 向量在列方向和 Hrow 向量在行方向上进行卷积;C=conv2(...,'shape') 用来指定 conv2 返回二维卷积结果部分，参数 shape 可取值如下： 》full 为缺省值，返回二维卷积的全部结果; 》same 返回二维卷积结果中与 A 大小相同的中间部分; valid 返回在卷积过程中，未使用边缘补 0 部分进行计算的卷积结果部分，当size(A)>size(B) 时，size(C)=[Ma-Mb+1,Na-Nb+1]。 应用举例A=magic(5) A= 17 24 1 8 15 23 5 7 14 16 4 6 13 20 22 10 12 19 21 3 11 18 25 2 9 B=[1 2 1;0 2 0;3 1 3] B= 1 2 1 0 2 0 3 1 3 C=conv2(A,B) C= 17 58 66 34 32 38 15 23 85 88 35 67 76 16 55 149 117 163 159 135 67 79 78 160 161 187 129 51 23 82 153 199 205 108 75 30 68 135 168 91 84 9 33 65 126 85 104 15 27 相关函数 filter2第01套 给定程序中,函数fun的功能
