这个问题需要长篇论文来回答,看来好像是英语文学硕士的考题吧,在这里我们不能做充分解答.给你下面一个答案,你自己另外补充吧.
There are at least two figures of speech used by Shakespeare in Hamlet Act 3 Scene 1:
1.Simili
be thou as chaste as ice,as pure as
snow,thou shalt not escape calumny.Get thee to a
nunnery,
2.Aporia
(Aporia is a form of rhetoric in which a claim is put in doubt by developing arguments on both sides of an issue.It expresses a contradiction or a paradox.)
To be,or not to be:that is the question.
Whether 'tis nobler in the mind to suffer
The slings and arrows of outrageous fortune,
Or to take arms against a sea of troubles,
And by opposing end them?To die:to sleep;
No more; and by a sleep to say we end
The heart-ache and the thousand natural shocks
That flesh is heir to,'tis a consummation
Devoutly to be wish'd.To die,to sleep;
To sleep:perchance to dream:ay,there's the rub;
For in that sleep of death what dreams may come
When we have shuffled off this mortal coil,
Must give us pause:there's the respect
That makes calamity of so long life;
For who would bear the whips and scorns of time,
The oppressor's wrong,the proud man's contumely,
The pangs of despised love,the law's delay,
The insolence of office and the spurns
That patient merit of the unworthy takes,
When he himself might his quietus make
With a bare bodkin?who would fardels bear,
To grunt and sweat under a weary life,
But that the dread of something after death,
The undiscover'd country from whose bourn
No traveller returns,puzzles the will
And makes us rather bear those ills we have
Than fly to others that we know not of?
Thus conscience does make cowards of us all;
And thus the native hue of resolution
Is sicklied o'er with the pale cast of thought,
And enterprises of great pith and moment
With this regard their currents turn awry,
And lose the name of action.
