问题 填空题

MOD(17,-3) 函数的返回值是______。

答案

参考答案:-1

解析: MOD函数是求余函数,格式是:MOD(<数值表达式1>,<数值表达式2>),功能是:返回两个数值相除后的余数。<数值表达式1>是被除数,<数值表达式2,是除数。余数的正负号与除数相同。如果被除数与除数同号,那么函数值即为两数相除的余数;如果被除数与除数异号,则函数值为两数相除的余数再加上除数的值。
由于被除数与除数异号,则函数值为两数相除的余数再加上除数的值,即2+(-3)=-1。

阅读理解

In my long years of teaching, I often ask my student to read the texts until they can recite(背诵) them, and I tell them that recitation is an important part of their homework. However, some of my students are tired of doing so, thinking that it is both hard and useless. They argue that it takes a long time to recite a text from memory and text itself never appears in a test paper.

In my opinion, it naturally takes time to recite a text, but it is worth doing so. When you are able to recite a text, you are sure to be familiar with the words and expressions. When you need them in reading or writing or doing exercises, they will come to your mind quickly, and so you will give quick response to all kinds of language situation. How can we say that it is useless?

Besides, many students complain that they soon forget what they were once able to recite. This is true, but you don’t need to worry. While you are reading and forgetting the texts, your language level is being raised. Sure you don’t remember your Chinese texts that you once read in the primary school, but now you are able to read novels and newspaper. So, recitation of the texts will help you improve your language ability.
