原文：“It is a question of discipline,” the little prince said to
me later on. “When
you’ve finished your own toilet in the morning,
then it is time to attend to the
toilet of your planet, just so, with the greatest
care. You must see to it that
you pull up regularly all the baobabs, at the very
first moment when they can
be distinguished from the rosebushes which they
resemble so closely in their
earliest youth. It is very tedious work,” the
little prince added, “but very easy.”
And one day he said to me: “You ought to make a
beautiful drawing, so
that the children where you live can see exactly
how all this is. That would
be very useful to them if they were to travel some
day. Sometimes,” he added,
“there is no harm in putting off a piece of work
until another day. But when it
is a matter of baobabs, that always means a
catastrophe. I knew a planet that
was inhabited by a lazy man. He neglected three
little bushes. . . ”
So, as the little prince described it to me, I
have made a drawing of that
planet. I do not much like to take the tone of a
moralist. But the danger of
the baobabs is so little understood, and such
considerable risks would be run by anyone
who might get lost on an asteroid, that for once I am breaking through
my reserve. “Children,” I say plainly, “watch
out for the baobabs!”
My friends, like myself, have been skirting this
danger for a long time, without
ever knowing it; and so it is for them that I have
worked so hard over this
drawing. The lesson which I pass on by this means
is worth all the trouble it has
cost me.
Perhaps you will ask me, “Why is there
no other drawing in this book as magnificent and impressive as this drawing of
the baobabs?”
The reply is simple. I have tried. But with the others I have not been
successful. When I made the drawing of the baobabs I was carried beyond
myself by the inspiring force of urgent necessity.
我的理解，这里have worked…..与it has cost….这两个事件用现在完成时，因为这边作者不知道过去事件发生的具体时间。
如果是“说话人关心的是过去事件导致的结果，该结果体现在现在，不关心过去” 我认为是不对的，比如I have eaten an apple.
我过去吃完一个苹果，吃完苹果是过去事件，这个事件影响到了现在的我，比如我可能还想吃一个或者太饱了。那么随后一定会加一句I am ful. 或者I want another one.所以这个现在时的意义时后面必须会加一句表示对于现在我的影响，影响如何。
