作“离开，溜走”解时，这五个短语多用于口语。其区别是：get along表示一般性的“离开”；go along作此解时用于祈使句，表示因不耐烦而要求对方“离开”，其后带with you；push along多用于暂时告别的场合，表示“离开”不久又会见面；run along 多用于长辈对孩子讲话的场合；toddle along尤指与朋友见面后分手。

along, toward, to
1.along表示“动向”时，方向性不明确，意为“沿着”；toward的方向性很强，意为“朝，向”；to除表示方向性之外，还有“到达”的意思。试比较下面一组句子：

他沿着河岸走。
He walked toward the bank.
他朝河岸走去。
On his way to the bank,he met a friend.
在去河岸的路上，他遇见一个朋友。
