C语言编程问题 该程序是完成两个数字的加减乘除 不知道为什么菜单项目会连续出现两次。
getch()修改为
chargetch(void)
{
charc;
puts("Entertheoperationofyourchoice:");
puts("a.adds.subtract");
puts("m.multiplyd.divide");
puts("q.quit");
scanf("%c",&c);//%c前空格用于过滤上次输入留在缓冲区的回车
returnc;
}
英语句子中会出现两个连续的to吗?
当然可能了。 I went to see my doctor to make sure that I was better.(两个不定式) He told the news to his father to make him happy. (第一个介词,第二个不定式)by 和on 的用法
介词by可以用来表示方位、时间、手段等,其用法在高考中曾多次出现。下面结合高考试卷和其它一些例句做一下归纳: 一、by+地点名词。表方位,意为:“在…旁边”。如:by the lake/river/tree/window/door等。 She searched the top of the hill and stopped to rest on a big rock by the side of the path.(NMET90)她搜索了山顶,然后停下来在路边的一块大石头上休息。 After supper she would sit down by the fire,sometimes for高中英语语法:There is no limit..........(有两种句型,一个是加to sth,还有一种是什么)
1. “more than one + 单数名词”虽有复数概念,但习惯上用单数动词。 2. C.except that except可以跟从句。 except + 从句 He cannot hide his feelings, except when the waiters ask if everything is all right. 除了在服务生问他是否觉得不舒服时之外,他无法掩藏自己的感觉。 (P24) 本句中含有介词except + when引导的从句作状语,很多同学对此不理解,其实except除了接名词、代词、介词短语、动词不定式外,还可接从句。如: 1. Everybody excit was planted where its tough roots which grow up to five feet long could help hold back the soil
分解各从句: A. it was planted (somewhere) 它被种植(在某处) B. its tough roots could help hold back the soil 它坚韧的根能帮助它抓牢泥土 C. (its roots) grow up to five feet (它的根)长到了五英尺 句法分析: ①A句为句子主干。主语:it。谓语:plant。地点状语:somewhere。 ②B句为A句的地点状语从句,以where引导。主语:its tough roots。谓语:could help。这里的hold是过去分词一般式 (done)作状语,修饰谓语动词,进一步说明谓语展开全文阅读
