Key Words of the Day
应该 means should. 去看病,go to see a doctor. 不用, no need; 午饭, lunch; 上网, to be or to go online.All in today’s Chinese Studio.

A: Hey, Yajie, how do you say should in Chinese.
Y: it’s应该
A: 应该. And as with helping verbs in English, the Chinese 应该 usually comes before the main verb in a sentence.
Y: right. here's a handy construction when you want to say a person should do something. It’s the name of the person or a pronoun + 应该 + what they should do. For instance: You should go to see a doctor. 你应该去看病。 Subject, 你, plus 应该, plus看病.
A: 你应该去看病。

A: 你应该去看病 (ni ying gai kan bing)。You should go to see a doctor.
Y: 不用, No need.
A: Bu (second tone) yong, no need.
Y: Remember we learned that 不, the fourth tone, should change to 不, the second tone, when it’s followed by another fourth tone character.
