Enjoy spring as we do in Lesson 16, unit 4 of Chinese Book Volume 2 of grade 4 The ellipsis omits what, urgent, online, etc What is omitted? Speed, today

This is the last sentence of the poem, which expresses a strong hope for stopping the war and maintaining peace, so that children suffering from war can return to school and enjoy spring and peace. The ellipsis in the poem omits a beautiful and infinite hope, which can be summarized in two words as "peace"!

In addition to Meili, fill in a sentence at the ellipsis of the penultimate paragraph to make it consistent with the preceding sentence in meaning and sentence pattern?
In a button flower, I understand the sentence in context, fill in the words expressing the mood of the characters in brackets, rearrange the serial number according to the original expression order, and write it below. Read the sentence, imagine the details of the ellipsis in context, and add it. (no less than 20 words) he picked up the button flower that I had been squeezed out and gave it back to me, but I actually How do you write it?
If the answer is correct, you will continue to add points. Time is running out,
It's reading "add to beauty" and "a button flower"!

The text content of "Little Match Girl" in the second volume of the sixth grade of people's Education Press

It's very cold. It's snowing and it's getting dark. It's the last day of the year - New Year's Eve. On this cold and dark night, a little girl with bare head and feet is walking in the street. When she comes out of the house, she still wears a pair of slippers, but what's the use? They are a pair of big slippers - so big, always worn by her mother

It's better to take the name of the method, such as cross multiplication, grouping and decomposition formula method, etc

As shown in the figure, given angle B + angle d = angle e, what is the position relationship between line AB and CD? And explain the reason

AB∥CD
It is proved that if we pass through point E, we can make ef ‖ AB (point F is on the side of B and D)
∵EF∥AB
← B = ∠ Feb (equal internal stagger angle)
∵∠E＝∠FEB+∠FEC
∴∠E＝∠B+∠FEC
∵∠E＝∠B+∠D
∴∠FEC＝∠D
‖ EF ‖ CD (equal internal stagger angle, two parallel lines)
‖ ab ‖ CD (two lines parallel to the same line are parallel)

Known: as shown in the figure, ad = AE, ab = AC, ∠ DAE = ∠ BAC

It is proved that: in ∵ bad and △ CAE, ad = AE, bad = caeab = AC, bad = SAS and BD = EC

How many liters per minute is 3600 cubic meters per hour

1 m3 / h = 1 × 1000 △ 60 L / min = 1000 / 60 L / min
3600 × 1000 / 60 = 60000 L / min

Logx y = log x (x > 0, Y > 0, X ≠ 1, y ≠ 1, X ≠ y), then XY=

If the top angle of isosceles triangle is 120 ° and the height on the bottom is 3cm, the waist length is______ cm．

As shown in the figure, ab = AC, ad ⊥ BC is at the point D, ad = 3cm, ∠ BAC = 120 °, ∫⊥ BAC = 120 °, ab = AC ∫ B = ∠ C = (180 ° - ⊥ BAC) △ 2 = 30 ° ∫ ad ⊥ BC ∫ AB = 3 △ 12 = 6cm

When as2294 AC voltmeter is used to measure sinusoidal AC voltage, the measurement is as follows:
A: Peak to peak;
B: Effective value;
C: Amplitude;

B: Effective value
