你提的问题很仔细.看来我也要认真学习.
这个小词通常就是连接两个名词或是两个句子或是更多的句字.也有"加"的意思.2 and 3 is 5.
1.It's "No Parking" area,and we have to leave.
这里这个"and" 是讲明结果的意思.
2.My aunt Lucy is an actress.She must be at thirty-five years old
3.Thanks,and wish you have a nice holiday too.(这句是我向我的朋友写E-Mmail时他回复我的
这句就是连接的意思了.也可以不用逗号.Thanks.And I wish...写信很随意,也不是很讲究或是考虑语法的.第二条我觉得用and 是不太妥,因为当演员跟年龄不是并列的关心.但如果你想说她是个演员并且是个好演员,你就可以用了.My aunt Lucy is an actress and she has received numerous awards.
介绍个网站,有问题也可问它.
祝好!
