the usage of 'except'

If "except" is at beginning of the sentence,"except for" is used,it is equal to "apart from".

i.e.

Except for/Apart from this thing,everything else is good.

All students go to cinema except John.

"must" and "may,might"

He looks very sadly,he must have gotten a bad score at last test.(express the deduction from known facts);

He may have gotten a bad score at last test.(express the possibility or conjecture)

If it is a logical reasoning then the word-'must' is used,or if it is a subjective guess then the word-'may' or 'might' is used.'May' express a stronger possibility than 'might'.

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).

"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

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)

  Remember words with LP5800.After finishing the strange words remembering of high school,I will remember ST words formally.

  Doing exercise of NCE 2 is a bit difficult to me,I planed finishing it within 3 months company with reading and remembering words.

  In order to realize my goal,I should be in a long fighting,the goal should be reached by bit add bit,so,despite the boredom feeling bothering me sometimes,I will learn something every day without interspace.Only in this way,can I achieve the aim.
