Presently she began again. `I wonder if I shall fall right THROUGH the 
earth! How funny it'll seem to come out among the people that walk with their heads 
downward! The Antipathies, I think--' (she was rather glad there WAS no one listening, 
thistime, as it didn't sound at all the right word) `--but I shall have to ask them what 
the name of the country is, you know. Please, Ma'am, is this New Zealand or Australia?' 
(and she tried to curtsey as she spoke--fancy CURTSEYING as you're falling through the 
air! Do you think you could manage it?) `And what an ignorant little girl she'll think me 
for asking! No, it'll never do to ask: perhaps I shall see it written up somewhere.'
Down, down, down. There was nothing else to do, so Alice soon began 
talking again. `Dinah'll miss me very much to-night, I should think!' (Dinah was the cat.) 
`I hope they'll remember her saucer of milk at tea-time. Dinah my dear! I wish you were 
down here with me! There are no mice in the air, I'm afraid, but you might catch a bat, 
and that's very like a mouse, you know. But do cats eat bats, I wonder?' And here Alice 
began to get rather sleepy, and went on saying to herself, in a dreamy sort of way, `Do 
cats eat bats? Do cats eat bats?' and sometimes, `Do bats eat cats?' for, you see, as she 
couldn't answer either question, it didn't much matter which way she put it. She felt that 
she was dozing off, and had just begun to dream that she was walking hand in hand with 
Dinah, and saying to her very earnestly, `Now, Dinah, tell me the truth: did you ever eat 
a bat?' when suddenly, thump! thump! down she came upon a heap of sticks and dry leaves, 
and the fall was over.

《Alice's Adventures In Wonderland》 CHAPTER1
by Lewis Carroll
Alice was beginning to get very tired of sitting by her sister on the 
bank, and of having nothing to do: once or twice she had peeped into the book her sister 
was reading, but it had no pictures or conversations in it, `and what is the use of a 
book,' thought Alice `without pictures or conversation?'
So she was considering in her own mind (as well as she could, for the 
hot day made her feel very sleepy and stupid), whether the pleasure of making a 
daisy-chain would be worth the trouble of getting up and picking the daisies, when 
suddenly a White
Rabbit with pink eyes ran close by her.
There was nothing so VERY remarkable in that; nor did Alice think it so 
VERY much out of the way to hear the Rabbit say to itself, `Oh dear! Oh dear! I shall be 
late!' (when she thought it over afterwards, it occurred to her that she ought to have 
wondered at this, but at the time it all seemed quite natural); but when the Rabbit 
actually TOOK A WATCH OUT OF ITS WAISTCOAT- POCKET, and looked at it, and then hurried on, 
Alice started to her feet, for it flashed across her mind that she had never before seen a 
rabbit with either a waistcoat-pocket, or a watch to take out of it, and burning with 
curiosity, she ran across the field after it, and fortunately was just in time to see it 
pop down a large rabbit-hole under the hedge.
In another moment down went Alice after it, never once considering how 
in the world she was to get out again.
The rabbit-hole went straight on like a tunnel for some way, and then 
dipped suddenly down, so suddenly that Alice had not a moment to think about stopping 
herself before she found herself falling down a very deep well.
Either the well was very deep, or she fell very slowly, for she had 
plenty of time as she went down to look about her and to wonder what was going to happen 
next. First, she tried to look down and make out what she was coming to, but it was too 
dark to see anything; then she looked at the sides of the well, and noticed that they were 
filled with cupboards and book-shelves; here and there she saw maps and pictures hung upon 
pegs. She took down a jar from one of the shelves as she passed; it was labelled `ORANGE 
MARMALADE', but to her great disappointment it was empty: she did not like to drop the jar 
for fear of killing somebody, so managed to put it into one of the cupboards as she fell 
past it.
`Well!' thought Alice to herself, `after such a fall as this, I shall 
think nothing of tumbling down stairs! How brave they'll all think me at home! Why, I 
wouldn't say anything about it, even if I fell off the top of the house!' (Which was very 
likely true.)
Down, down, down. Would the fall NEVER come to an end! `I wonder how 
many miles I've fallen by this time?' she said aloud. `I must be getting somewhere near 
the centre of the earth. Let me see: that would be four thousand miles down, I think--' 
(for, you see, Alice had learnt several things of this sort in her lessons in the 
schoolroom, and though this was not a VERY good opportunity for showing off her knowledge, 
as there was no one to listen to her, still it was good practice to say it over) `--yes, 
that's about the right distance--but then I wonder what Latitude or Longitude I've got 
to?' (Alice had no idea what Latitude was, or Longitude either, but thought they were nice 
grand words to say.)
Presently she began again. `I wonder if I shall fall right THROUGH the 
earth! How funny it'll seem to come out among the people that walk with their heads 
downward! The Antipathies, I think--' (she was rather glad there WAS no one listening, 
thistime, as it didn't sound at all the right word) `--but I shall have to ask them what 
the name of the country is, you know. Please, Ma'am, is this New Zealand or Australia?' 
(and she tried to curtsey as she spoke--fancy CURTSEYING as you're falling through the 
air! Do you think you could manage it?) `And what an ignorant little girl she'll think me 
for asking! No, it'll never do to ask: perhaps I shall see it written up somewhere.'
Down, down, down. There was nothing else to do, so Alice soon began 
talking again. `Dinah'll miss me very much to-night, I should think!' (Dinah was the cat.) 
`I hope they'll remember her saucer of milk at tea-time. Dinah my dear! I wish you were 
down here with me! There are no mice in the air, I'm afraid, but you might catch a bat, 
and that's very like a mouse, you know. But do cats eat bats, I wonder?' And here Alice 
began to get rather sleepy, and went on saying to herself, in a dreamy sort of way, `Do 
cats eat bats? Do cats eat bats?' and sometimes, `Do bats eat cats?' for, you see, as she 
couldn't answer either question, it didn't much matter which way she put it. She felt that 
she was dozing off, and had just begun to dream that she was walking hand in hand with 
Dinah, and saying to her very earnestly, `Now, Dinah, tell me the truth: did you ever eat 
a bat?' when suddenly, thump! thump! down she came upon a heap of sticks and dry leaves, 
and the fall was over.
Alice was not a bit hurt, and she jumped up on to her feet in a moment: 
she looked up, but it was all dark overhead; before her was another long passage, and the 
White Rabbit was still in sight, hurrying down it. There was not a moment to be lost: away 
went Alice like the wind, and was just in time to hear it say, as it turned a corner, `Oh 
my ears and whiskers, how late it's getting!' She was close behind it when she turned the 
corner, but the Rabbit was no longer to be seen: she found herself in a long, low hall, 
which was lit up by a row of lamps hanging from the roof. 
There were doors all round the hall, but they were all locked; and when 
Alice had been all the way down one side and up the other, trying every door, she walked 
sadly down the middle, wondering how she was ever to get out again.
Suddenly she came upon a little three-legged table, all made of solid 
glass; there was nothing on it except a tiny golden key, and Alice's first thought was 
that it might belong to one of the doors of the hall; but, alas! either the locks were too 
large, or the key was too small, but at any rate it would not open any of them. However, 
on the second time round, she came upon a low curtain she had not noticed before, and 
behind it was a little door about fifteen inches high: she tried the little golden key in 
the lock, and to her great delight it fitted!
Alice opened the door and found that it led into a small passage, not 
much larger than a rat-hole: she knelt down and looked along the passage into the 
loveliest garden you ever saw. How she longed to get out of that dark hall, and wander 
about among those beds of bright flowers and those cool fountains, but she could not even 
get her head though the doorway; `and even if my head would go through,' thought poor 
Alice, `it would be of very little use without my shoulders. Oh, how I wish I could shut 
up like a telescope! I think I could, if I only know how to begin.' For, you see, so many 
out-of-the-way things had happened lately, that Alice had begun to think that very few 
things indeed were really impossible.
There seemed to be no use in waiting by the little door, so she went 
back to the table, half hoping she might find another key on it, or at any rate a book of 
rules for shutting people up like telescopes: this time she found a little bottle on it, 
(`which certainly was not here before,' said Alice,) and round the neck of the bottle was 
a paper label, with the words `DRINK ME' beautifully printed on it in large letters.
It was all very well to say `Drink me,' but the wise little Alice was 
not going to do THAT in a hurry. `No, I'll look first,' she said, `and see whether it's 
marked "poison" or not'; for she had read several nice little histories about 
children who had got burnt, and eaten up by wild beasts and other unpleasant things, all 
because they WOULD not remember the simple rules their friends had taught them: such as, 
that a red-hot poker will burn you if you hold it too long; and that if you cut your 
finger VERY deeply with a knife, it usually bleeds; and she had never forgotten that, if 
you drink much from a bottle marked `poison,' it is almost certain to disagree with you, 
sooner or later.
However, this bottle was NOT marked `poison,' so Alice ventured to 
taste it, and finding it very nice, (it had, in fact, a sort of mixed flavour of 
cherry-tart, custard, pine-apple, roast turkey, toffee, and hot buttered toast,) she very 
soon finished it off.
`What a curious feeling!' said Alice; `I must be shutting up like a 
telescope.'
And so it was indeed: she was now only ten inches high, and her face 
brightened up at the thought that she was now the right size for going through the little 
door into that lovely garden. First, however, she waited for a few minutes to see if she 
was going to shrink any further: she felt a little nervous about this; `for it might end, 
you know,' said Alice to herself, `in my going out altogether, like a candle. I wonder 
what I should be like then?' And she tried to fancy what the flame of a candle is like 
after the candle is blown out, for she could not remember ever having seen such a thing.
After a while, finding that nothing more happened, she decided on going 
into the garden at once; but, alas for poor Alice! when she got to the door, she found she 
had forgotten the little golden key, and when she went back to the table for it, she found 
she could not possibly reach it: she could see it quite plainly through the glass, and she 
tried her best to climb up one of the legs of the table, but it was too slippery; and when 
she had tired herself out with trying, the poor little thing sat down and cried.
`Come, there's no use in crying like that!' said Alice to herself, 
rather sharply; `I advise you to leave off this minute!' She generally gave herself very 
good advice, (though she very seldom followed it), and sometimes she scolded herself so 
severely as to bring tears into her eyes; and once she remembered trying to box her own 
ears for having cheated herself in a game of croquet she was playing against herself, for 
this curious child was very fond of pretending to be two people. `But it's no use now,' 
thought poor Alice, `to pretend to be two people! Why, there's hardly enough of me left to 
make ONE respectable person!'
Soon her eye fell on a little glass box that was lying under the table: 
she opened it, and found in it a very small cake, on which the words `EAT ME' were 
beautifully marked in currants. `Well, I'll eat it,' said Alice, `and if it makes me grow 
larger, I can reach the key; and if it makes me grow smaller, I can creep under the door; 
so either way I'll get into the garden, and I don't care which happens!'
She ate a little bit, and said anxiously to herself, `Which way? Which 
way?', holding her hand on the top of her head to feel which way it was growing, and she 
was quite surprised to find that she remained the same size: to be sure, this generally 
happens when one eats cake, but Alice had got so much into the way of expecting nothing 
but out-of-the-way things to happen, that it seemed quite dull and stupid for life to go 
on in the common way.
So she set to work, and very soon finished off the cake.
