Stressed and unstressed syllables in poetry - help needed?

[Calc Guy]

In the poem, "I wandered lonely as a cloud" by William Wordsworth, I am having problems marking these two lines:

Fluttering and dancing in the breeze.

Continuous as the stars that shine

To put them in context, the poem goes:

I wandered lonely as a cloud
That floats on high o'er vales and hills,
When all at once I saw a crowd,
A host of golden daffodils;
Beside the lake, beneath the trees,
FLUTTERING AND DANCING IN THE BREEZE.

CONTINUOUS AS THE STARS THAT SHINE
And twinkle on the milky way
They stretched in never-ending line
Along the margin of a bay:

Thanks for any help!
