the computer or computers / about or without about
which one is correct,whether(1) ,(2),(3) or 4) please explain.
(1)On the other hand,the computer may bring about some negative change.
(2)(1)On the other hand,Computers may bring about some negative change.
(3)On the other hand,the computer may bring some negative change.
(4)On the other hand,computers may bring some negative change.

首先我觉得你这四个句子当中的change都应该改成复数的changes会比较好一点.因为change在作为“变化,改变”讲的时候是可数名词,这个时候如果是有some的话应该加上复数的changes比较好一点；当change作零钱的时候讲的时候才是不可数名词,所以这个时候才可以说some change.
所以这些句子当中的change应该都改成复数形式比较好一点
第一句不太正确因为computer是一个可数的实意名词所以应该加上冠词或者用复数这里就单单用了一个computer的原型语法上不对
第二句是比较正确的.Computers这里不是强调有很多电脑,而只是说明电脑这一类东西,由于是可数名词所以要加复数
第三句语法上其实也没有错,但是一般可数名词想说那一类东西的话直接用名词的复数比用定冠词the 加名词单数要好一点因为只是指出这一种类而不是要强调这个种类 the通常有特指的意味
第四句和第二句差不多就是bring和bring about的区别,bring当然就是带来的意思了,在这个句子中说得通,而bring about有带来造成引起的意思意义更多在这个句子中的意义也是正确的而其中“引起造成”这个意思在这个句子中可能还更好一点
综上我觉得比较好的还是第二句和第四句其中最适合的我觉得还是第二句吧
On the other hand,Computers may bring about some negative changes.
