以下是3個例句供您參考：It is supposed to be a car,but it is a truck.本來期望是輛小車的,可卻是個卡車.He was supposed to be at the meeting.他本應出席那個會議的.We were supposed to be on the train,not he...謝謝你的句子，順便幫我看看這兩個也對嗎？謝謝It's supposed to snow next week. 下周因該要下雨It's supposed to have a sand storm in the spring.兩句都沒問題，就是第2句的 sand storm 最好連起來寫，是一個詞，指“沙塵暴”。
