日积月累

1、三思而后行：Look before you leap.

2、三句话不离本行：They talked shop.

3、入乡随俗：When in Rome do as the Romans.

4、昙花一现：A nine days' wonder

　　A nine days' wonder means person or thing that attracts attention for a short time but is soon forgotten，昙花一现的人或事物。

这里的nine days形容时间很短，并非表示“九天”这一具体的时间。

5、百闻不如一见：Seeing is believing.

6、才疏学浅：be wanting in ability and shallow in knowledge
