Bai Juyi
From the north side of Gushan Temple to the west side of Jiating, the lake is just level with the embankment, with low clouds and waves on the lake.
Several early warblers competed for warm trees, and their new swallows pecked at new soil.
Colorful spring flowers will gradually fascinate people's eyes, and shallow spring grass can barely cover the horseshoe.
I love the beauty on the east bank of the West Lake, and I can't get enough of it, especially the white sand embankment under the green poplar.
"Double swallow. Chasing the Spring Club (Songshi Dazu)
After the Spring Festival, the curtain is in the middle.
Last year was cold and dusty. Poor Poole wants to live,
Try to blend in. And carved a beam caisson,
Soft language and uncertain quotient.
Floating quickly blows the flower tip, and the green tail is separated from the red shadow.
Fang Jing, celery mud and rain.
Love clings to the ground for flying and glory.
It's late in the Red Chamber.
You have to stay in your fragrance and forget it.
Worried about the harm to Cui Dai moths, I paint alone every day.
2. The poem "The forest is quieter with cicadas singing, and Tonamiyama is quieter" shows the quietness of nature. The following reproductive information about cicada, a and cicada is sexual reproduction through the combination of bisexual reproductive cells, which does not meet the meaning of the question.
Metamorphosis is an important phenomenon in the process of insect growth and development. After three stages: fertilized egg, larva and adult, it does not meet the problem.
C, the breeding mode of birds is oviparous, which does not meet the meaning of the question.
D, the process of bird embryo development is divided into two stages. Embryo development during egg formation and embryo development during incubation. The eggs discharged from the ovary by birds are accepted by the oviduct funnel, and then meet the sperm for fertilization. Because the hen's body temperature is as high as 465438 0.5℃, the egg begins to develop soon after fertilization. Until the egg is produced in vitro, the fertilized egg continues to divide for about 24 hours, forming a multicellular embryo. In fertilized eggs, germ cells divide in the process of oviduct, forming a disk-shaped gastrula with a transparent center and dark periphery, which is called blastoderm. It can be seen that bird embryos are developed in vitro, which is consistent with the problem.
So choose: D.
