帮忙看看有无英语语法错误.Before I study Japanese,I always think Japanese

Before I study Japanese,I always think Japanese is easy to study,because I have already known some words’ meaning in Chinese.But to my surprise,during the study time,I found some interesting Japanese words having amazing meanings.Now,I will take 3 examples to you.
-----------------------------------------------------------------------------------------------------------
Why do Japanese have their power to face disaster and difficulties?Because of their faith .Japan don’t have samurai now,however,they also believe in the spirit of samurai.
Samurais are known to their faith and loyalty.Samurai often mentioned by writers to glorify.It is a honor to be a real samurai.A samurai must be treated a lot of skills,such as shooting,sword skills even dancing and traditional music.
The spirit of Samurai to Japanese likes western people believe in God and eastern people believe in Lord Buddha.I think it’s necessary to explain that we need a faith in our hearts.No matter what.
-----------------------------------------------------------------------------------------------------
In Japan,spring is not judged by the weather but the time when CHERRY BLOSSOMS bloom.
This year,Japan’s spring is later than that last year.Because of the bad weather.Japanese are strongly reckon that CHERRY BLOSSOMS may bring them lucky and happiness.
只能帮你这么多了....

（1）because I have already know(要用known，have done 是完成时)（2）Samurai （少了is） often mentioned by writers to glorify。（3）The spirit of Samurai to Japanese （少了is，be like 像什么，系动词） like western people 。（个人观点，如若差错，请批评指正。）

有一些语法错误Before I study Japanese应为Before I studied Japanese我认为是典型的中文式英语.(个人观点，有冒犯处，请原谅)
