Help, hurry!! Otherwise, tomorrow will be dead!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

I won't change my mind, I just won't.

The marble is carved into a bell, and the bronze is cast into a bell, and I am a person who is made with loyalty, even if it is broken or broken, I am loyal every piece.

In the faint moonlight, when you see my note, recognize my handwriting, and if the handwriting is true, everything is true.

What do I ask of you, no, nothing, I just want to love, to give everything I have while I live.

Perhaps, all I ask for is your trust.

Our love is not a private gift, our love is a spark focused on a goal.

Ah, when I approach you, there is fragrance all around;

When I left you, I still carried your aftertaste;

It is the fragrance of your virtues, and the slightest wisp of it has become my nourishment.

I'll admit, I think about you a lot.

You are my courage when I act;

You are my calm while I meditate;

You are my smile while I sleep;

You are my tears when I am excited.

Oh, thou hast never weakened me with appeasement when I was wounded;

When I bleed profusely, you did not panic;

When I am weak, you are the strength that supports me.

I know that I don't belong to you, you don't belong to me, we are two wheels connected to a steel axle, we both belong to this great era.

Suppose we don't go to war.

The enemy with bayonets.

Kill us, and point to our bones and say, "Look, this is a slave!" ”

That's all I found......

Common methods in Ming methods include: giving examples, listing numbers, making analogies, classifying, comparing, quoting, drawing charts, defining, interpreting, and copying.

1) Give examples.

Giving practical examples to illustrate things and making the things to be explained concrete so that the reader can understand them is called an example. Benefits: Make the meaning of the article clearer, more vivid, more understandable to readers, and enhance persuasiveness.

2) Quote.

Reflect the accuracy of the explanatory language. Quoting ancient poems: Make the expository more poetic.

3) Make comparisons.

Comparison is an explanatory method that compares two kinds of things and phenomena of the same or different categories to illustrate the characteristics of things Advantages: Explain some abstract or relatively unfamiliar things, and use concrete or familiar things to compare with it, so that readers can get a concrete and distinct impression through comparison.

4) Column numbers.

In order to make the thing to be illustrated concrete, you can also use the method of column numbers so that the reader can understand. It should be noted that the figures quoted must be accurate. Benefits::

Numbers are the most accurate, scientific, and convincing basis for quantitatively describing the characteristics or facts of things. (The method of using numbers to explain can not only accurately and objectively reflect the facts, but also have strong persuasive power.) ）

5) Categorization.

To explain the characteristics of things, it is often difficult to explain them from one side, and things can be divided into several categories according to the similarities and differences in their shape, nature, cause, function, and other attributes, and then explain them one by one according to the categories. This method of explanation is called categorization. Benefits::

It's organized and clear at a glance.

6) Analogy.

The method of using the similarities between two different things to compare them, to highlight the characteristics of the things, and to enhance the vividness and vividness of the explanation, is called analogy. Benefits: Abstract facts become concrete, vivid, and vivid.

Or explain the characteristics of things in a specific and easy-to-understand way. ）

7) Glossary appearance.

In order to make the object to be explained more vivid and concrete, it is possible to copy the appearance, and this method of explanation is called 摹 (mó) appearance. Benefits: Make the object of the description more vivid and concrete.

8) Definitions.

A prescriptive description of the essential characteristics of a concept in plain language is called a definition. Defining things reveals exactly what they are. Benefits: Enables people to understand abstract words more clearly and comprehensibly when reading.

9) Interpretation.

10) Draw diagrams.

In order to explain complex things clearly, you can also use the chart method to make up for the lack of text alone, and explain some things more directly and concretely.

What do you mean? Fill in the blanks? Is there a previous article? What is the problem?

Set the speed of the passenger car x m sec and the truck speed y m sec.

10(x+y)=400

100(y-x)=400

x=18 m-s y=22m-s.

v total = (250 + 150) divided by 10s = 40 (m seconds).

v difference = (250 + 150) divided by 100s = 4 (m seconds).

So V customer = 22 (m s) V cargo = 18 (m s).

The bottom of the is subjected to the pressure p of the water

P = GH = 1 10 kg m 10N kg 55m = PAP max = GH max.

H max = p max g = 6 10 5 pa 1 10 kg m 10n kg = 60m

It is also permissible to raise the water surface height = h max - h = 60m - 55m = 5m

sn+1 = 2sn + a1；

sn = 2sn-1 + a1；

Subtract one from the two.

Get. an+1 = 2an

Geometric progression. an = 2*（n-1），a1 = 1；

(1) The effect of pressure force.

2) The magnitude of sliding friction is related to the roughness of the surface of the object.

3) Wood blocks with different surface roughness should not be selected.
