i really don't understand this..can someone explain?

f.e.Divide into immediate constituents:
1.Full-scale computers have a large number of programs
2.We must change all the programs tomorrow
3.Tomorrow will be a holoday free

Thank you for using the Jiskha Homework Help Forum. Here are some explanations of immediate constituents:

1. http://en.wikipedia.org/wiki/United_States_House_of_Representatives

2. http://www.thefreedictionary.com/immediate+constituents

3. http://www.britannica.com/eb/article-9042190/immediate-constituent-analysis

What you are to do is linguistically explain the word order.
