Time difference

There's a 17 hours time difference between Vancouver and Tokyo. When I first came to Vancouver, I couldn't sleep at night. Moreover, I was always sleepy in the daytime. It was a very hard experience for me. We have only one time zone and no summer time daylight savings time ("summer time" makes it seem like you don't have the summer season) in Japan. It took a long time to get used to the time difference.

"Subscribe to" is what you would say when you subscribe to a newspaper or magazine. It is the term used for that. However, Amazon has launched a platform that manages what you subscribe to. They say "subscribe with Amazon" as using Amazon to manage your subscriptions. So only ever use "subscribe to" when talking about subscriptions.

The scary blond

This is a true history of my town. In Aracaju, state capital of Sergipe in Brazil, there is a scary blonde woman scary. She rides in a motorcicle with another person. She has cotton on the her nose and on the her heard. There is blood in the cotton. When it gets nigth  dark (or you can say 'when night comes') around 10 pm, she starts to scare all the people that walks in place whithout someone. She stops in the front at of schools to scare the school lookout. She and your pilot (pilot?) stay next to de the driver´s car and scare them. The perfect place which she uses to scare is a dark place. She gets next to you and makes you shake and get scared.

In English it is important to remember that we conjugate it/she/he with an s ending, which is your most common error. ("it/she/he USES' is correct 'it/she/he USE' is incorrect)

Statements - New vocabulary.

1- I will store these groceries in the pantry. THEREAFTER, I will do the dishes. ('thereafter' is usually used when referencing the past so this example seems off. 'I stored the groceries in the pantry, Shorty thereafter, I did the dishes.')
2- She enjoyed CHANTING that song ['part' is better here] in the song.
3- He's kind of a GREEDY guy.
4- Some people MOCKED him the first time he made a mistake dancing with the group.

(Correct and make suggestions if you are a native English speaker or an English teacher. Thanks in advance)

5- Our friends came here to URGE us to go to the bar and drink.
6- He was such as so angry that he only BLURTED out to her “get out here!” (I think blurted has an unexpected connotation, 'He blurted out the answer without raising his hand.')
7- Izalco’s volcano was called “LIGHTHOUSE of the Pacific” because of its long LAVA ERUPTION.
8- In 2005 Santa Ana’s volcano had an ASH ERUPTION.
9- They are earning BIG BUCKS!
10- I don’t think I HAVE THE PIPES when I speak English. (Pipes usually refers to singing, not just speaking in general, 'I don't think i have the pipes to sing that song.')

Besides those slight definition changes the grammar looks good.

Reading

As Like you, I'm learning a foreign language. And  Something that I realized is that if you combine the language learning with a daily activity that you like, you will not only learn faster, but the learning process will be more entertaining.

There are a lot of methods to learn and improve in a foreigner language, and one of my favorites is reading. because If you read often in your target language, you will improve your language skills in a lot of ways: you will increase your vocabulary, you will improve your pronunciation, you will understand better the grammar better, and you will also acquaint yourself with the culture of some countries where people speaks your target language (something useful if you are learning ['want' might be a better word here] to travel).

Fortunately, on the internet you can find a lot of learning resoursces designed to for people who enjoy reading, so all you need is to search something that you like.
