See the above questions, you choose the answer, although it is just a few very simple security questions, but we may not be able to find the correct answer when we see it, when I see such a few questions, I found that I was confused all of a sudden, although it is a very simple safety question in the first grade of primary school, but, when I do it, I find that I chose the wrong one, for example, the first question, its correct answer is C. The correct answer to the second question is A, and the answer to the third question is AIn fact, I also had a lot of doubts at that time, but the standard answer is the standard answer, and when you look carefully, people still have ulterior motives to formulate such three standard answers. This is a first-grade test question, and I am an undergraduate graduate but found the trouble, not that the primary school students must be able to do all the right, this is also a test for us, sometimes I am very proud, I will also find that the current primary school students' test questions, a very simple topic, and you understand it is very complicated, or a very complex question, the result is simple, and there are all kinds of mistakes, I can really say that the first grade of primary school test questions, give you a test paper you can get 100 points. I remember that I found a few words I didn't know in the textbook of the first grade of primary school, so when I saw it, I found that some books still have a little meaning, no matter what kind of book it is, as long as we read it, it is beneficial to open the book, although the capacity of the book content of primary school students is very small, but there are also some more remote and strange, but we have not been exposed to it. Sometimes we realize that primary school books are not necessarily simple. The current textbooks have been revised many times, if you know all the knowledge, maybe you will really be proud, not to mention that there are a few words in the first grade of primary school English that I don't know, even I can't read accurately, there is still plausible knowledge, you should be humble.

In the face of these little knowledge, it is also incredible. Simple things are not simple, these little knowledge is often needed in our lives, not those very remote things, and we will still be in front of such a need of things, every time there will be some of our own choices, and such small knowledge, when a teacher will make a mistake, I am also a little incredible! But I also think that this kind of knowledge is very interesting, very practical, so I took a little effort to write out the test questions of these small knowledge, and then write out the options, and finally show the answers to everyone, I hope that when you see these three questions in your future life, you can choose the right method and the correct answer, especially the third test question, the option of artificial respiration, I suddenly chose such an option as artificial respiration, but the standard answer is not like this, and later compared it only to find that people's answers are better, and every time we choose may have a profound impact is artificial respirationSometimes what we adults think is different from what children think, our world is our world, and the world of children is the world of children, so we must see the world in other people's world, not in our own eyes.

I don't know what's wrong with it lately, but I've been reading some students' textbooks lately, and then I found out that I don't know a lot of knowledge, not to mention finding time for me to do practice problems, there will be a lot of loopholes! Occasionally, if I am given a junior high school test paper, I will feel very difficult and do very badly, but if I am given a high school test paper, maybe my loopholes will be even greater, and I will feel so much pressure on the test papers of primary school students, and I should probably be like others, starting from the first grade of primary school, and then learn the knowledge again.

And the knowledge of elementary school students is the best, because the textbooks they use have been reviewed by many experts over and over again, so there are high-quality textbooks and books, so I think the textbooks used by children are the best books! And I found out that I have no thorough understanding of such textbooks, or should have some comprehension of the textbooks, or do some training on such books and knowledge, sometimes I find that there is nothing bad about doing some children's test questions, although now I am an adult, although I feel that my thinking should be the key to the thinking of people, but I have no adult knowledge, although I am not a child, but there is no child-like knowledge, only to find out that it is really a very strange thing, for example, last semester my nephew wrote the Chinese pinyin homework, every time the exam has to mark the toneThis may be the difference between our adults and children, they are learning knowledge at this age, so they learn very firmly, but if they learn the knowledge of higher grades, maybe the knowledge of this age will be forgotten occasionally! This is the memory of the human brain, sometimes learn a lot of knowledge, but also forget a lot of knowledge, but this knowledge has become our things. Maybe it's a step-by-step process, slowly in such an era that has become our knowledge, slowly our knowledge is growing, our way of thinking is also growing, there will be more and better status quo, there will be a better future, these little knowledge is very important in our lives, sometimes it may really need to be used, it will cause a very important result in our lives, so learn more such little knowledge!
