今天打掃工作的故事

我的朋友前幾天說他認識一位需要打掃服務的人。我們安排今天早上我自己一個人去他家。但是約的九點沒人開門。我打電話對方不接，就打電話給朋友。他也不知道發生什麼事。我發現這個人是他同事但是很少一起工作也很少交談。但是那個同事突然埋怨說了家裡太髒要找人來打掃，我的朋友就推薦我。我等了半個小時還是無法聯絡所以我就走了。直到中午他就打電話給我說抱歉說他忘了，然後問我下午可以來嗎？但是我下午沒空，而且我跟他說，早上的時間我還是要他付錢因為浪費時間。還好他的態度沒差，很願意，不跟我吵架。我之前有經驗態度實在太差的客戶。

It means that the votes have all been cast and Britain has voted to leave the EU.

If only you corrected my writing ^^* -> Please correct my writings

Because I was am eager to improve my English speaking ability in order to be a global talent communicate globally. I took a year off from my university and went to Seoul. And then, I registered for an English academy and moved into an accommodation for examiners.
My class started at 7:30, and a group study finished at in evening. After that, I studied more until night. I shadowed listening listened to audio files while on my way home. I was going back home. And I practiced pronunciation in the shower. I fell asleep, after reviewing what I had learned that day.
It was dreadfully hard and lonely, but I got through that 6 months course. And eventually my English ability has was improved so much that my friends couldn’t believe it.
After the course, I headed for Australia to use English. I got to know Australian culture and new perspectives to see the world saw the world with a new perspective, living with Australian friends whom I still keep in touch with.
With these kind of patience and my enthusiasm to help me improve my English ability rapidly, I can hope to bring about good results to Bosch.
