must-see

(humorous) Tom’s washing the dishes—I must be seeing things!

汤姆在洗碗——肯花眼了！

We must see the reverse as well as the obverse side of things.

"们既要到事的正,也要到事的。"

We must see that there is no gap in our defence.

们必须确保们的防御没有漏洞。

The government must be seen to be whiter than white.

政府必须让自己上去公正廉洁。
