题目内容
In every language there are two great classes of words which, taken together, consist of the whole vocabulary. First, there are those words with which we become acquainted in daily conversation, which we learn, that is to say, from the members of our own family and from our familiar associates, and which we should know and use even if we could not read or write. They concern the common things of life, and all the goods in trade of all those who speak the language. Such words may be called "popular", since they belong to the whole people; and are not the exclusive possession of a limited class. On the other hand, our language includes a large number of words which are comparatively seldom used in ordinary conversation. Their meanings are known to every educated person, but there is little occasion to use them at home or in the market place. Our first acquaintance with them comes not from our mother’s lips or from the talk of our schoolmates, but from books that we read, lectures that we hear, or the more formal conversation of highly educated speakers who are discussing some particular topic in a style raised above the habitual level of everyday life. Such words are called "learned". And the distinction between them and "popular" words is of great importance to a right understanding of the language. From the passage, we can infer that ______.

函数ReadDat()的功能是实现从文件ENG62.IN中读取一篇英文文章，存入到字符串数组xx中。请编制函数encryChar()，按给定的替代关系对数组xx中所有字符进行替代，仍存入数组xx的对应的位置上，最后调用函数WriteDat()把结果xx输出到文件PS62.DAT中。 替代关系：f(p)=p*13mod256(p是数组xx中某一个字符的ASCII值，f(b)是计算后新字符的ASCII值)，如果计算后f(p)的值小于等于32或其ASCII值是偶数，则该字符不变，否则将f(p)所对应的字符进行替代。 注意：部分源程序已给出。 原始数据文件的存放格式是每行的宽度均小于80个字符。 请勿改动函数main()、读函数ReadDat()和写函数WriteDa()的内容。 #include＜conio. h＞ #include＜stdio. h＞ #include＜string. h＞ #include＜ctype. h＞ unsigned char xx[50] [80]; int maxline=0; int ReadDat (void); void WriteDat(void); void encryChar() void main() clrscr (); if ReadDat ()) printf ("数据文件ENG62. IN不能打开! \n\007"); return; encryChar (); WriteDat (); int ReadDat (void) FILE *fp; int i=0; unsigned char *p; if ( (fp=fopen ("ENG62. IN", "r") ) ==NULL) return 1; while (fgets (xx [ii, 80, fp) !=NULL) p=strchr(xx[i], ’\n’); if (p) *p=0; i++; maxline=i; fclose (fp); return 0; void WriteDat() FILE *fp; int i; fp= fopen ("ps62.dat", "w"); for (i=0;i＜maxtine; i++) printf ("%s\n", xx [i] ); fprintf (fp, "%s\n", xx [i] ); fclose (fp);
遗传素质的成熟程度制约着身心发展和______。
企业拥有一宗土地面积为20亩的国有出让土地，规划建设40000m2综合大楼和20000m2公寓，预计2年建成后即全部售出。企业甲在完成前期投入后，拟将该宗地转让给房地产开发商乙。 经调查，该城市相似地段相同功能的综合楼售价为6000元/m2，公寓售价为4500元/m2，同类结构的综合楼工程建筑费及专业费为2100元/m2，公寓为1800元/m2，在建筑期间，建筑费及专业费第一年投入40%，第二年投入60%，银行贷款年利率为5.5%，开发利润为总售价的15%，销售税税率为售价的5.5%。 根据上述情况，回答以下问题。 经甲乙双方协商，房地产开发商乙准备以开发完成后的部分房地产按售价的90%给甲作为地价的补偿，开发后的房地产销售税费由乙统一支付，如不考虑甲的前期投入和土地转让税费，试问甲除可得到14000m2综合楼外，还可分得( )m2的公寓。
