In my opinion,Wordsworth aimed at simplicity and purity of the language,fighting against the controvertional forms of the 18th century.The poet was a passionate lover of nature and his descriptions of lakes and rivers,of meadows and woods,of skies and clouds are exquisite.
I think it will be helpful if you try to gain more knowledge of the Romantic Period,the background and the features of the time.You can also find help in those masters' beautiful Chinese translations.Wish you good luck.
