In regard to ship
I find in oxford dictionary "ship" also can be used as a verb to refer to sending goods by other means of transport apart from by ship, as follow:
Your order has been shipped by air / sea / rail. You should receive it by this weekend.
If goods are sent by truck, how to express this by using "ship", for example, your order has been shipped by road /trunk ?
one more question, can I put "by" in front of " this weekend" as the above sentence shown ?

If you note in my sentences above any grammar mistakes or incorrect words, please kindly point them out , thanks in advance.

Answer

"Your order has been shipped" is normal, and probably more common than "been sent". In this context the word has lost it's close connection to the noun "ship". The verb came from a time when ships were a common way to send things. 
Now it has a very similar in meaning to "send". It is a verb extensively used in business. Most large companies have a shipping/receiving department for goods arriving and leaving the building.

You sent things by air, rail, truck, taxi, the post office, or courier - always "BY". No one says "by road" or "by trunk" - trunk is an outdated word.
