英语中逗号与分号的区别、用法

Answer 1

逗号一般出现在长句子中，一般在连接词前，比如说and、but等。
分号一般很少出现。

当你看见有but, and, also, as well as, because, so 等等的字眼时. 例句:

I didn't wake up on time this morning so I was late for school. (逗号在 so 前面是可有可无, 一般不会写因为第二个句子自己不能独立, 不能算完整所以可有可无, 只是为原本的句子做注解而已)

当两个句子都是独立时, 逗号就一定得在but, and, also, as well as, because, so
等等词后面用上, 如:
I didn't wake up on time this morning.
I had a very bad headache. 两句都是独立句. 加在一起时, 逗号必须出现:
I didn't wake up on time this morning, because I had a very bad headache.

如果是用however, therefore, thus, on the other hand诸如此类的, 其实是要用 ; <<分号
例句: I didn't wake up on time this morning; therefore, I was late for school.
2. I didn't wake up on time this morning; however, I didn't have to anyway as it is a public holiday.

逗号与分号加在一起的的例句:
I didn't wake up on time this morning, I even ran into traffic, and my bike was broken; therefore, I was very late when I finally got here.

Answer 2

dima,b
a=1
b=2
printa,b
printa;b
你把这段代码运行一下下，就知道逗号和分号的区别了。至于冒号，一楼说的对，是用于在一行中写两个以上语句的分隔符。如a=1:b=2:printa,b:printa;b，等同于上面代码的写法。

Answer 3

逗号表示很短的停顿。1，用于并别名词，形容词，动词，短语之间。
2，用于描述性定语之前
3，用于同位语之前
