Ask for a master, hey!!! Hurry, hurry

The English spoken in Britain and the United States, the evolution of the English language, the historical development, and what else is important about English today, how many percent of the people in the world are learning and using English, like what homophones disagree with words, and a sentence that is not repeated with 26 letters, the quick brown fox jumps over a lazy dog

A quick brown fox jumps over a lazy dog. )

This sentence uses only 32 letters, but it completely includes 26 letters in English, so it is one of the best materials to practice typing. There is another sentence, which also uses only 32 letters, but it is far less universal than the first sentence. The sentence is:

pack my box with five dozen liquor jugs.

Packed five dozen bottles in my box. )

In fact, there are still many sentences that contain 26 letters in English but are shorter than the above two sentences, such as the following sentence that uses only 31 letters:

the five boxing wizards jump quickly.

Five boxing wizards throb rapidly. )

If you want to write this kind of sentence with fewer letters, you'll probably have to use proper words. A sentence like the one below uses only 29 letters:

quick wafting zephyrs vex bold jim.

The wind overwhelms the brave Jim. )

The other sentence is shorter, using only 28 letters:

Waltz Nymph, for quickj igs vex bud, the goddess's brisk waltz moves infuriate Bard. )

The last sentence is even more worthy of the finale, using only 26 letters. Unfortunately, it contains two proper nouns, and it is also a proper noun with abbreviated letters, which greatly reduces its mystery by speculation. The sentence is:

flung my box.

Drop with my box.

It is said that if someone can use 26 letters of the English language, write a sentence without repeating any proper nouns, and the Guinness Book of World Records will include his name.

Here are a few exceptions.

It is recommended that you write a speech in Chinese and then translate it into English.

The reasons are generally as follows:

1. The total load of household appliances exceeds the power capacity of the switch. For example, if the total power consumption of an appliance running at the same time is up to 10kW, the circuit current can be reached, and if the rated current of the switch is only 30A, it will trip due to overcurrent protection. You can observe whether there are too many high-power appliances (air conditioners, instantaneous water heaters, etc.) turned on at home when tripping, if so, turn off some of the electrical appliances to see if it can be solved, if some are turned off to solve, it means that it is indeed caused by overload, and you can replace the switch with a higher current.

2. There is leakage in electrical appliances, and leakage protection. This situation is more dangerous, and it must be checked in time, especially the electrical appliances and wiring in the bathroom, kitchen and other places where the environment is relatively humid.

3. Overheating protection caused by aging of switches and poor contact. Replace it in time.

Either way, it's best not to replace it yourself, unless you know the principle of strong electricity very well, it is highly recommended to find a professional electrician to get it.

There are generally two reasons for tripping, one is that you have too much electrical equipment in your home, and sometimes the centralized power consumption is too large and overloaded. It is possible to replace the electrical switch with a slightly larger capacity. Second, it may be that the contact of a certain electrical appliance line in your home is not good, and there is an instantaneous short circuit, please carefully find the cause and eliminate the hidden danger.

If it was normal before, then it may be that the switch is broken, change it.

One is that the empty drive is broken, and the other is where there is a short circuit.

There are several reasons for tripping, you have to check the line at home, overload, short circuit, undervoltage, overvoltage, and leakage will cause tripping. If you can't find out why! It is recommended that you find a property electrician to check and deal with this problem.

Suggestion! You get a professional electrician! Help you.

(5) Surface area = 24 square centimeters.

Edge length = root number (24 6) = 2 cm.

Surface area = 54 square centimeters.

Edge length = root number (54 6) = 3 cm.

Surface area = 294 square centimeters.

Edge length = root number (294 6) = 7 cm.

The volume of the cube = 2 2 2 + 3 3 3 + 7 7 7 = 378 cubic centimeters (6) Solution: Let the length, width and height of the cuboid be a, b, and h respectively, then the meaning of the question is obtained:

ah=32，bh=20，abh=160

Then, 160 = ABH = 20A, then A = 8 cm 160 = ABH = 32B, then B = 5 cm.

Therefore, the base area is as: ab = 8 5 = 40 (square centimeters) Answer: The bottom area is 40 square centimeters

144*(6 Kuan7)=168

Substituting x=-2, y=3 2 into the equation is obtained.

kx-2（x-1/3y²）+3/2x+3/1y²）=-2k-2[2-1/3(3/2)²]3/2*(-2)+3/(3/2)²]

2k-4+3/2+3+4/3

2k-1+9/6+8/6

2k+11/6

Substituting x=-2, y=3 2 into the equation is obtained.

kx-2（x-1/3y²）+3/2x+3/1y²）=2k-2[(-2)-1/3(3/2)²]3/2*2+3/(3/2)²]

2k+4+3/2-3+4/3

2k+1+9/6+8/6

2k+23/6

The results were the same both times.

2k+11/6=2k+23/6

2k+2k=11/6-23/6
