我们做翻译推理时，为了加强训练，需要多刷类似的题目，但真题有限，遂使用JS代码写一个简单的随机出题程序（其实是2021年写的代码）。

一、核心功能

首先，翻译推理常见的连接词如：

• 如果……那么……
• 若……则……
• 只要……就……
• 所有……都……
• 为了……一定（必须）……
• ……是……的充分条件

那么我们可以定义连接词的数组为：

let s1=["除非", "只有", "只要", "除非", "为了", "为了"]
let s2=["否则", "才", "就", "否则", "一定", "必须"]

然后需要语法完整，并定义一些人名：

let s0=["小明", "小红", "小张", "小李", "小郑", "小赵"]
let s3=["去看电影", "去吃饭", "去电影院", "去上课", "去考试", "去睡觉", "去消费", "买手机", "买电脑", "去上班"]

然后随机一些选项，从s3数组取，并加上“→”即可。

那么随机题目的完整函数如下：

...
         setQues(){
				this.uNum++
				//1:推导 2:相同语句
				let qType = this.cswRandom(1,2)
				switch(qType){

二、完整代码展示

现在随机出题完毕，需要让用户作答训练，且都喜欢使用手机训练，于是这里采用Uniapp（基于Vue）开发，可以编译成WEB端网页、微信小程序、app等。
