想問present continuous and present simple的分別

第一句用this year ---今年正在工作,是持續性,
第二句用this year----今年之內完成,有時間限制,不會無止境地興建同一間車房.
用present simple tense----表示每日都做的事情,一種習慣性,永遠的事實.
until next month and weekends---在指定時間之內完成

sometime present continuous tense can be used as future tense. so here the second sentense mean he is going to build a garger this year.

你呢度兩句都係用緊present continuous喎

但第二句就用build(present simple)會合理d,因為

present continuous用在一個特定時間裡面動作不斷發生,而現在進行的
而present continuous亦有強調現時動作的作用

present simple 用在一個特定時間發生的事

我諗你唔明既係動作(即係work,build之類)同個時間既關係,而唔係this year就一定用present simple或者present continuous,而係你有冇需要話俾人聽你呢樣野係現在進行中,如果唔洗既話,就咁present simple就ok

如果第二句用is building,就會好似變左要講你鄰居由現時到今年都起緊個車房,唔係好合理

1. present continuous because 現在進行 - is working
2. present simple = present tense = 現在式
