I like the rain  (the is optional but I think it is better with it)
I like the rain.  I like to stand by the window watching the rain. There is a river near my home.  While it is (its is a possessive noun, different from it is) raining I look out through the window; the river is misted, opening its mouth swallowing the rain and at that moment I like to hear the sound of joy from the rain running into the river. I like walking in the rain with an umbrella.  when it is raining all people look funny.  Some people without an umbrella run fast, som other people get completely wet (you can also use soaked). Some people cursing the rain look very unhappy.  Some women with beautiful dress watch out for splashes when the cars pass by. I like walking in the rain with an umbrella, hearing the sound of the rain dropping on my umbrella, like music. I really like the rain's sound. I love this rainy evening. Hearing the rain's sound, thinking of the past time and old friends I have not seen for a long time...
Tonight it's raining! (end it with an exclamation point to give it more force).

English illiterate

I do not speak English, you can not write an essay in a foreign language

Dear Lily,

You were able to write a full sentence in English.  You should feel proud of yourself.  I will help you with English and I hope you help me with Chinese.

Here is the correct sentence:

English illiterate (this was written correctly!)

I do not speak English, I can not write an essay in a foreign language.  (Only one correction.  Keep writing please, I will help you) 

Weather in chendu

Chendu relocates in south west of china.four seasons are clear.spring is warm summer is hot and rainey and muggy.autumn is Rainey and cloudy,winter is mostly cloudy and warm ,seldom sunny because chengdu relocates in a basin .i dislike winter because I seldom see the sun .

Lina, remember to capitalize proper nouns like Chengdu.  This is an important rule in English.  Names of people, places, countries, etc, must always be capitalized.

Also, always start with a capital letter after a period.  

Relocates:  to switch places, to go to a different place
Locates:  position, situation or whereabouts

NOTE:  These two words are easy to confuse because they sound similar.  The secret is in recognizing the "re" before "relocates", which in this case gives the word a different meaning.

Rainey, as Mark already corrected it, the word is rainy.  Just remove the "e" from it.  

Please keep writing, you have a natural way of expressing your thoughts in English and I honestly encourage you to keep doing it.  Congratulations on a job well done!
