use activity diagram to model a system
Only a flavouring.
I found to use activity diagram to build a system model is a good choice for me.Instead of modeling with sequence diagram,I model another model of filesharing with activity diagram.
Now I have finished the analysis model,base on this,I will make a design model in my spare time.
NCE L19:can,could,may,might
1.request permission;
polite:can(friends and equals)<could,may<might(superior)
2.may/might + infinitive
may/might + perfect infinitive
3.may/might as well + infinitive
for example:
I might as well play game( as learn english-it makes no difference).
remember some triangle functions
(1)sinA+sinB=2sin((A+B)/2)cos((A-B)/2);
(2)sinA-sinB=2cos((A+B)/2)sin((A-B)/2);
(3)cosA+cosB=2cos((A+B)/2)cos((A-B)/2);
(4)cosA-cosB=-2sin((A+B)/2)sin((A-B)/2);
I haven't finish today's learning plan-only finished 4 pages of 10 pages.That's ok,I am a lazy man today.I am not a machine.
"have" and "have got"-L18
When "have" expresses the meaning of "possess",it equal to "have got".
For example:
This sock has (got) a hole in it.
This room has (got) four windows.
But in the sentence below,it cann't be replaced by "have got":
They had a good time at the party.
its meaning is:to enjoy or suffer;experence,often as part of a group
At this viewpoint,"have" is a unversal word.for example:have meal,have letter,have a look,have it...
We can view these in LONGMAN dictionary.p701-702
No passion,only an aim
A ten pages a day,a lesson a day,one hundred a day...
No passion,no interesting,only aim.
Aim is first,other is second,other is surrounding this aim.
This is my life.
Persist.
I'll begin to learn Mathematics
Learning math has been started.
An initial plan,root on the book,ten pages a day.'A' first.
Today,it is a first ten pages.
Persist,I will finish it.
Wish me successful.
Mathematics(数学)
From a viewpoint,Mathematics is one of the bases of the program.
NCE L17:"must" versus "have (got) to"
There are two way in "must".
First,it says:this is your necessity,you have to face it.at this meaning,it has no PAST tense and FUTURE tense itself.
PAST TENSE:I had to do it.
FUTURE TENSE:I will have to do it.
Second,it says:this is your obligation.This is a deduction.at this meaning,it can express a past action: (modal + perfect inifitive) He must have done it.
Another point:
I have to do it.(no contraction)
I've got to do it.(the contraction is always used)
