短文改错（共10小题，每小题1分，满分10分）
For most people, it is almost impossible to operate on a computer without a mouse, let alone surf the Internet. A well-chosen mouse is really handy, flexible and convenience in controlling the screen. Without the functions of inserting, deleting, moving and copying, it enables us to edit text, browse web pages and download that we want. It can even bring us a flood of musics, movies and PC games. Just imagining, all that can be done with a cute mouse.
A convenient tool can certain make our work easier, and it doesn’t always help in a positive way. Too much ready information on our fingertips leaves a little room for knowledge pursuing. Too many ready answers make us less excited in finding truth. Relying too much on mouse clicking make us much lazier and less creative.去掉 on

(答案→)去掉 on 解析：【小题1】去掉 on 动词operate作为操作时，是一个及物动词，后面直接加宾语，不需介词。【小题2】convenience---convenient 本句要使用convenient与前面的flexible同样都是形容词。【小题3】Without---With 本句中没有否定的含义，是指有插入，删除，移动和复制等功能，电脑可以让我们进行编辑等操作。【小题4】 download^all 或that---what 本句可以使用宾语从句用what引导；也可以使用定语从句，that指代all在句中作为动词want的宾语。【小题5】musics---music 名词Music是不可数名词，没有复数形式。【小题6】imagining---imagine 本句是祈使句，just后面直接加动词原形。【小题7】certain---certainly 本句中使用副词certainly修饰动词短语make …在句中作状语。【小题8】and---but 上下文之间是转折关系。方便的工具能让给我们的工作更加容易，但是并不能总是起积极作用。上下文之间存在着转折关系。【小题9】去掉a 本句中含有否定的含义，太多的信息给我们留下的空间是很少的。【小题10】make--- makes 本句使用动名词做主语，谓语动词用单数形式。
