I want real answers, urgent, I want answers?

Dear landlord.

Glad for your question.

Some things or some things, some people, when people have it, do not know how to cherish it, love it, once it is lost, they feel the preciousness of its existence and the value of use, but all regrets are irretrievable.

The cup is lonely, being poured boiling water, the feeling of being hot, so the cup thinks this is the feeling of love, when the water becomes warmer, the cup feels very comfortable, I think this is the feeling of life, the water is cold, the cup is very scared, I think maybe this is the feeling of being afraid of losing, the water becomes cold again, the feeling of the cup is also very uncomfortable, I don't want to have a tasteless feeling, so I want to pour the water out、、、 the water is finally poured out, at this time the cup feels very comfortable, but it is also poured to the ground at the same time, Broken into pieces, the cup found that on every fragment, there will be traces of water, it knows that it still loves water in its heart, it wants to love water again but it is impossible, is it only lost will know how to cherish? Only when everything has passed does you know the happiness of the past? The facts have warned us to cherish what we have now, and not to regret it until we lose it, but it's too late.

Reality is always cruel, it doesn't give us that chance, some things are missed and won't come back.

Please forgive me if my own is inaccurate!

Your original answer is right I hope the subject will not be afraid of mistakes in the future, because the wrong question will not have any impact on you at all, and the teacher will not beat you, he will only carefully teach you how to do this topic.

Answer: 90 degrees.

Analysis: Point d1 is the point on the plane add1a1, which is used to refer to the plane add1a1;

Point B is a point on a planar ABCD, which is used to refer to a planar ABCD;

ad is the intersection of two planes.

Solution: From the cube, we can see that a1a is perpendicular to ad, ba is perpendicular to ad, and a1a intersects ba at the point b

So the angle baa1 is the planar angle of the dihedral angle d1-ad-b.

From the cube, we can see that the angle baa1 is 90 degrees.

Therefore, the size of the dihedral angle d1-ad-b is 90 degrees, and the "because" and "so" symbols are not easy to play, if it is more perfect, it can be in the format of "because" and "so").

a.Social insurance and commercial insurance can be cross-handled.

The object-orientation of the two is different, and one is enforceable, and the other is a contractual relationship; One is legislated, the other is based on commercial principles. There are no factors that interfere with each other in the two, so there is no overlap when handling them. Therefore, it can be cross-handled.

This seems to be a question for the civil service test, and a teacher talked about this question some time ago, and he explained it like this.

34.Urbanization is profoundly changing China. Today, China's urban population has surpassed the rural population, and the "agrarian society, rural China's metallurgical society" has gradually transformed into an "industrial society, urban China's metallurgy."

Urbanization has accelerated the process of rural modernization in China, and a new era of urban civilization seems to be quietly coming.

In the wave of urbanization, a large number of villages have been merged, and many distinctive traditional villages have been disappearing. The kind of pastoral scene depicted in the song "On the Field of Hope" is "a piece of winter wheat, a piece of sorghum, ten miles of lotus ponds, and ten miles of fruity fragrance." Someone said sadly

Don't ask me if I'm from, because I don't have a hometown anymore.

1) Use knowledge of cultural life to explain why some people feel sorry for the decline of the countryside. (6 points).

2) Use the knowledge of the basic attributes of contradiction to explain how to understand the relationship between urban civilization and rural civilization in the process of urban dialect (6 points).

1) The countryside is an important carrier of traditional culture, and the decline of the countryside is not conducive to the inheritance and development of excellent traditional culture. The countryside carries the characteristic cultures of different regions and is an important embodiment of cultural diversity. The countryside entrusts people's nostalgia and homesickness, which can enhance people's sense of identity and belonging to Chinese culture.

2) Contradiction is the unity of opposites, and struggle and identity are the inherent basic attributes of contradiction. Urban civilization and rural civilization are different, and there are differences in the mode of production, lifestyle, and value concept of the two, and each has its own characteristics. Urban civilization and rural civilization are interdependent and interconnected.

Urban civilization needs to be beneficially nourished by rural civilization; Rural civilization also needs to be renewed, developed and improved with the help of urban civilization. In the process of urbanization, we should organically unify the promotion of urban civilization and the care of rural civilization.
