(Set suspense to arouse readers' thinking. The rhetorical device of parallelism is used, and through six consecutive questions, the language potential is enhanced, and the sense of rhythm is strong, which also shows the author's strong interest in science and strong thirst for knowledge. Continuous questioning arouses readers' thinking and imagination, and also opens the floodgates of the author's thinking, allowing readers and the author to imagine the mysterious world hundreds of millions of years ago and listen to the fantastic myths told by fossils.

(2) What is the relationship between the last verse and the second verse, and where is it written? What are the advantages of calling fossils "you" in poetry?

Ordinary truth refers to Darwin's view in the Origin of Species, that is, organisms evolved from low to high, and from low to high. )

3. How to understand that "the black body wraps the information of life and leaves a precious password for history"? ?

Because organic compounds, the basic substances of life, remain in fossils, providing the necessary conditions for scientific research. )

4. "Time wrinkles your face, just like sketching the archives of life"? How to understand it?

("Carving wrinkles" is a metaphor to describe fossils. Facial wrinkles are portraits of the course of life. Comparing fossils to facial wrinkles shows that fossils are witnesses to the history of the earth, which is a metaphor, vivid and concrete. )

(1) What rhetorical devices are mainly used in poetry? Please give an example and explain their functions.

(2) The language of poetry is subtle, but it contains rich contents. Analyze the meaning of the following sentences.

A You led my thoughts to ancient times and painted a picture of biological evolution. Fossils make people imagine the process of biological evolution.

B you deny the existence of the creator, and the cold bones answer the ordinary truth. Fossils prove that the world is material.

C time wrinkles your face, just like carefully drawing the archives of life. Fossils can record the evolution of life.

Fourth, summarize the full text.

Ai Qing

How vivid the action is,

How energetic,

Jumping in the waves,

Floating on the sea;

Unfortunately, when the volcano erupts,

Could be an earthquake,

You lost your freedom,

Buried in dust;

Hundreds of millions of years later,

Geological survey team,

Found you in the rocks,

Still lifelike.

But you were silent,

Not even a sigh,

Scales and fins are intact,

But can't move;

You're absolutely still,

No response to the outside world,

Can't see the sky and water,

I can't hear the waves.

Pure gold is difficult to preserve.

Frost [America]

Natural new green is pure gold,

This color of hers is the most difficult to preserve.

Her new leaves are like a flower;

But only for a moment.

Then it becomes a sharp sword,

Heaven is in sorrow,

The exposure time is just during the day,

All pure gold is hard to keep.

This is a poem praising youth. The poet refers to youth as "flower" and "pure gold", which shows the preciousness and beauty of youth. The poet suggested that time flies and we should cherish our youth. This is consistent with the meaning expressed by "don't be idle, the teenager's head is white and worried" and "the teenager doesn't work hard, the old man is worried". )

Our Soil Mother (Excerpt)

Gao Shiqi

Our mother soil,

It's a female worker in a soil factory.

In the construction plan of nature,

She bears the burden.

The most important work of several departments.

She preserves minerals, plants and animals,

There are microorganisms invisible to the naked eye;

She transforms matter, develops life,

Operating inorganic and organic,

The great project of two worlds.

She lives on the first floor of the earth's surface,

From inches to thousands of meters deep,

Are all in her field of work.

There's a waterway under her,

Below the waterway is an unbreakable hard shell.

She is a midwife of plants.

In her warm arms,

All the buds and green leaves are open,

Rocking all kinds of flowers and fruits,

Root and she hugged tightly.

She is a nanny for animals.

On her flat rocking bed,

Jumping frog and mouse,

Ants and earthworms are marching,

Curled pupae and parasites.

In the countryside, there are countless fields,

Dropping on the sweat of farmers,

Sow millet, wheat and sorghum.

Our mother soil,

Never let down the peasants' hopes.

The great project of transforming nature,

Turn the desert into an oasis,

From desolation to prosperity,

Our mother soil,

Further develop her work.
