英语翻译I learnt many things from my classmates ,such as studyin

1.楼主正解.
such as视为一个介词,所以后面如果是动词,则变成动名词形式.
所以后面用studying和being.
2.such as后面当然可以加and.
and表示对such as后面的例子的并列连接.
1）如果有and so on,则such as后面列举的例子中不能再出现and；
2）如果没有and so on,则一般such as后面的例子中一直使用逗号,但是最后两个例子用and连接即可.
当然如刚好只是两个例子,则之间用and连接.
3.如：
I have many friends,such as Tom,Lucy,Lily and so on.
I have many friends,such as Tom,Lucy and Lily.
I have many friends,such as Tom and Lucy.
