Thank you a lot for your corrections. Let me know if everything is OK now.

1) First, Chaucer describes the genle spring rain, which ends the drought of March.
2) Then he mentions the plants whose life source has such a powerful liquid that it sprouts the flowers.
3) Finally, he refers to Zephyrus, the harbinger of spring, which blows gently over each grove.
4) In Greek mythology, Zephyrus was the gentle god of the west wind. The wind is personified and it is said to bring nature back to life.
5) Another example of personification in line 8 where “his half course” refers to “the young sun” .
6) Aries, the first sign of the Zodiac, or the Ram, has the strongest sun in March and April. This implies that it is the end of April.
7) The little birds are singing because they also experience the regenerative powers of spring.

1. gentle (sp)

2. ... that it makes the flowers sprout.

4. delete "it"

5. add "is" before "in line 8"

The rest is fine.
