我觉得如果你喜欢他，那么你更应该请她吃饭了。

Wǒ juéde rúguǒ nǐ xǐhuān tā, nàme nǐ gèng yīnggāi qǐng tā chīfàn le.

I think that if you like her you, then you should invite her out to eat.

明天他应该也会去。

Míngtiān tā yīnggāi yě huì qù.

Tomorrow he should also be able to go.

累了一天，你应该要好好休息一下吧。

Lèi le yì tiān, nǐ yīnggāi yào hǎohāo xiūxi yíxià ba.

After a tiring day, you should take a good rest.
