有關英文句子問題詢問

假如你係在直接對話/通訊...不會講on the coming xday的。這是比較公式化的寫法-例如文件通告才會這樣。
I have decided to go to Causeway Bay with you this Sunday.

岩岩wash 完衫
的英文寫法是
Benny has completed washing his shirts.
留意不是說你的動詞錯has washed本身不是錯的動詞格式
只是英語人不會用has washed shirts這種語法
英文是比較要求描述精細和表達出來的(反觀中文很多時是以含意詞組...
例如啱啱洗完英文的動作是強調"做完"-"洗"這工序，所以不寫has washed(除非"洗"本就是那行動)而要寫has completed washing把wash動詞變為名詞(洗的工序)，而shirts亦要求表達清楚是甚麼shirts而不只是他洗了一堆衫(就算你是講他已經洗了一堆衫也要略詳細寫成He has washed many shirts / He has washed a large pile of shirts.才算是英文。

你寫的句子只能說是小學(學英文)形式的句子，並不是真正的英文句子。

---The present perfect tense in grammar is the form of a verb that shows a period of time up to and including the present (Is it up to the present tense?), and in English Language is usually formed with have and a past participle(=have decided=have washed;)
Perfect means being the form of a verb that shows a period of time up to and including the present (present perfect),past (past perfect), or the future(future perfect), (as in "He has gone.","He had gone.", "He will have gone."
About the tense:-
(1)I have decided to go to Causeway Bay with you (Tommy) coming Sunday.
present perfect=have and a past participle=have decided.
(2)Benny has washed shirts=added word just-Benny has just washed shirts;
present perfect=has and a past participle=has washed.
has just washed my shirts(=it seems to have just washed)(That's just perfect tense), (=has washed shirts already), (=has washed shirts just yet=not used with the simple past tense, yet with the present perfect tense.)It is considered more correct in British English to read:-has just washed----have already washed-----Has shirts been washed yet?

頂你唔順，我諗只有 TomingBB 先可以答你。同埋Benny 洗完衫變左男定女。
