首先,我明白he she it 係要+s,因為第3身單數[雖然唔係幾知咩野黎]
但係點解they唔洗+s呢?不只一個人呀
eg,most people like going on hoilday
第2,the new bmw sports car [has] a top speed of 220 km %.用has係因為220個數字?
the sun goes down in the west.點解又要+s呢?
最後一問,我是在other 知識睇到的

不明之處係.有個回答: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]
咁,唔係要用was or were咩?
