But I cannot sing aloud Quietness is my farewell music; Even summer insects heap silence for me Silent is Cambridge tonight! 对于建立的文本文件，使用read()读文件在屏幕上显示并进行词频统计。

freq = {}
for word in words:
    if word in freq:
        freq[word] += 1
    else:
        freq[word] = 1

print('\n词频统计结果：')
for word, count in freq.items():
    print(f'{word}: {count}')

Very quietly I take my leave
As quietly as I came here;
Quietly I wave good-bye
To the rosy clouds in the western sky.

The golden willows by the riverside
Are young brides in the setting sun;
Their reflections on the shimmering waves
Always linger in the depth of my heart.

The floating heart growing in the sludge
Sways leisurely under the water;
In the gentle waves of Cambridge
I would be a water plant!

That pool under the shade of elm trees
Holds not water but the rainbow from the sky;
Shattered to pieces among the duckweeds
Is the sediment of a rainbow-like dream?

To seek a dream? Just to pole a boat upstream
To where the green grass is more verdant;
Or to have the boat fully loaded with starlight
And sing aloud in the splendor of starlight.

But I cannot sing aloud
Quietness is my farewell music;
Even summer insects heap silence for me
Silent is Cambridge tonight!
