英语中逗号,和and又什么作用?
Large files need a lot of upload traffic and considering the average low upload rates of today's service providers,it is just natural that the downloads take their time.
这里的and前是一句简单句,and吧它和后面的句子练成一句是吗?
这里逗号的作用是什么?
it指的是前面的一正句嘛?

是构成并列句（又称“并列复合句”）.
并列句的连接方式有两种：
1.分号
2.逗号 + 连词 (and ,or ,but ,for 等,用以表达两个分句间的逻辑关系)
被连接的两个句子,可以是简单句,也可以是主从复合句,甚至并列复合句.连接后,就成为一个句子.
构成并列句的两个分句应该有逻辑联系,不能毫不相干.
and的主要作用是把两句或多句连在一起，使意思更加通顺，更加连贯。
我想应该是吧
