The method of comparing reading and writing is 5, and the method of comparing reading and writing is

The expository essay mainly tests the candidate's ability to accurately obtain information from the text, and the questions are mainly considered around accurate reading, accurate comprehension, and accurate screening.

Interference factors are often set up in the test questions: (1) Increase, decrease, expansion and contraction, that is, change the sentence of the original text, and expand or shrink the scope by adding certain words or reducing certain words. (2) Confusion is the use of plausible words or sentences to replace the correct one, causing ambiguity.

3) Reversal refers to deliberately disrupting the sentence relationship of the original text when setting options, resulting in difficulty in understanding, such as reversing the causal relationship and confusing the order. (4) Making something out of nothing, that is, using the inertia of the examinee's thinking, inducing the examinee to replace sober rational thinking with taking it for granted.

In the procedure for solving the problem, there is a sentence that slips smoothly: "Read the original text first, then read the question stem to make marks, find out the corresponding sentences in the range, and compare the options to see the difference." ”

Read the original text first and complete 3 tasks: (1) Understand the gist of the article, that is, the object of the explanation, the connection between the paragraphs, the author's opinions and related materials. (2) Label paragraphs with serial numbers. (3) Mark important sentences and key words.

Secondly, it is important to read the stem, and mark important words. For example, in the first question of the 1999 volume, the following mark can be made: "A hypothesis is proposed in the first paragraph of this article, and the one that is incorrectly understood is "3 marked".

The first is where the proposition points are located, the second is the content of the test questions, and the third is the criteria for selecting the answers.

Third, finding out the scope of the answer and the corresponding sentence is the substantive stage of the answer. In general, the search interval of the answer should be near the proposition point, such as the answer to question 1 in paragraph 1 or paragraph 2. It is more important to find the corresponding sentence, so to speak, if you find the corresponding sentence, you basically find the answer.

Comparing options to find the difference is the final step, which is to complete the answer. For example, Question 1 (b) says, "Hibernating mammals have changed over a wider range than humans."

The word "regulatory" was omitted, which did not match the original meaning of the article.

Direct selection, i.e., the correct answer is selected directly. This method is suitable for questions that are clear at a glance, and some of the answers can be determined at once. It also applies to "non-selection questions", such as selecting "incorrect one" and "one item that does not conform to the context".

The method of elimination, which can be applied to all types of multiple-choice questions. It improves the accuracy of the answer by excluding the options that do not meet the requirements of the question, revealing the correct answer. In order to find the "first knowledge point" with the elimination method, that is, the basis for the exclusion of the option to be excluded first, there must be two characteristics:

One is to judge the most accurately, and the other is the most valuable, and more options can be excluded after determining this knowledge point.

Analogy, which is suitable for partial multiple-choice questions. Quickly rule out certain options based on reasonable inferences, or infer unknown situations based on what is already known, and quickly determine the answer.

Reading: The integer part is read according to the reading method of integers, and the decimal part reads each number in turn!

Writing: The integer part is written according to the way the integer is written, if the integer is 0, write 0, and write the decimal point in the lower right corner of the single digit, written as a small dot"."The decimal part is written out in turn! Coincidentally, I just happened to be on this!

Example: Read: 72.83.

Reading: The integer part is read according to the reading method of integers, and the decimal point is read"Dot", the decimal part reads each number in turn!

Writing: The integer part is written according to the way the integer is written, if the integer is 0, write 0, write the decimal point in the lower right corner of the single digit, and write each number in turn for the decimal part!

Normal reading before the decimal point, decimal point reading"Dot"Each digit after the decimal point is read directly, e.g. 18.26.

Both the reading and the writing should be from a high position.

The teaching of the unit "Reading and Writing Multi-Digit Numbers" is the last stage of teaching whole integer reading and writing in primary schools. Through the teaching of this unit, students will be able to read and write multi-digit numbers correctly and quickly, and lay a good foundation for better learning the four operations of integers in the future.

Among them, the reading and writing of multi-digit numbers with 0 in the middle and end of the number is one of the difficulties in teaching. Because when reading, sometimes the written 0 is not read, and sometimes it has to be read out completely; And when writing numbers, all zeros have to be written out in full, and students tend to read less and write less or read more and write more. How can we solve this problem better?

In teaching, teachers can let students take the method of "grading first, then reading and writing" on the basis of students' mastery of reading and writing within 10,000, so that they can receive better teaching results.

The so-called "grading first, then reading and writing" is to follow the habit of counting in China, first divide a multi-digit number from right to left, and divide every four consecutive digits into a "number level" (the last number level does not have to meet the four consecutive digits, and the name of each number level is called "individual level", "10,000 level", "100 million level") in turn), and then read and write from the highest number level according to the level. Specifically:

1. Multi-digit reading.

The steps are:1According to China's four-digit grading method, draw a multi-digit scale (you can use a pencil to lightly draw a horizontal line below the multi-digit number).

2.From the highest position, read down step by step, and the reading method of each level is read according to the reading method of the number of each level (that is, the number within 10,000), and then add the name of the level "billion" or "10,000" after the level of 100 million or 10,000. 3.

If a number has a 0 in the middle or several zeros in a row, it will only read a zero, and the 0 at the end of each level does not have to be read. For example:

The method of grading first, then reading" can help students correctly read out the multi-digit numbers with 0 in the middle or 0 at the end, and only need to memorize the six digits of "100 million, 10000, 100, 10, 10", which reduces the burden of memory.

Second, the way to write multiple digits.

The steps are:1Determine how many scales the number to write and make a flag at the same time.

If the highest level is 100 million, you can use a pencil to gently draw three horizontal lines; If the highest level is 10,000, draw two horizontal lines. 2.Write the thousand, hundred, ten, and grade names of each level from left to right under the horizontal line of each level.

3.From the high to the low, write down one level at a time, except for the empty space in front of the highest significant digit without 0 to make up the four digits, wherever there is a vacant position in the rest of the scale, use 0 to make up the four digits. For example:

Write one million six hundred thousand four hundred and forty two.

One hundred million and six thousand is 100006000.

Grading first, then writing numbers", which can make students write less or write less 0.

Teaching practice has proved that "grading first, then writing numbers" is an effective way to improve students' correct reading and writing of multiple digits. Once students have mastered and become familiar with the method of "grading first, then writing numbers", the form can be simplified, the relevant process can be omitted, and the speed of reading and writing multiple digits will be improved.

Read is just to read out the data in the read-only memory inside the chip, while write is to change the data in the read-only memory again.

It's pretty much the same in the literal sense.

Read fast, of course!

For example, when reading data, it is to read the data from the hard disk into the memory, and the hard disk head only senses the magnetic medium of the disk, and writes from the memory or other storage to the hard disk when writing. However, it is necessary to change the magnetic properties of the magnetic medium of the disk.

It's kind of like reading a CD, and engraving a CD, do you think that's fast?
