What are the two ancient poems about rural scenery learned in the second volume of Chinese in grade four?

It's not cost-effective to look for flowers by yourself by the river.

(Tang) Du Fu (Song) Ye Shaoweng

Huang Si's maiden is full of flowers, so she should have pity on her teeth.

Thousands of flowers bent the branches. Small mouth firewood flies for a long time.

Butterflies have been dancing, but the garden can't be closed in spring.

Charming songbirds sing freely. An almond came out of the wall.
