Seeking the second year of junior high school ancient prose reading comprehension questions, to attach the answer
I'm a fan of online literature. I can't provide the questions and answers for reading comprehension in the second year of junior high school. However, I can provide you with some advice and guidance on reading ancient texts. Reading ancient prose was an art form that required high reading ability and cultural attainments. When reading ancient texts, you are advised to pay attention to the following points: 1. Understand the background of the article and need to understand the background of the era and the identity, status, cultural background of the author in order to better understand the content and meaning of the article. 2. Understand the structure and expression of the article: The expression of ancient Chinese is very different from that of modern Chinese. It often uses implicit euphemism, metaphor and symbolism. You need to understand its expression and rhetoric to better understand the meaning of the article. 3 Pay attention to the rhythm and rhythm of the article: Ancient prose often has its own unique rhythm and rhythm. You need to pay attention to the rhythm and rhythm of the article in order to better feel the emotions and thoughts of the article. 4. Read more and practice more: Reading ancient texts requires more reading and practice. You can improve your reading ability and memory by reading and reciting repeatedly. The following is an ancient text reading exercise for your reference: There was a passage in the Analects of Confucius, Duke Ling of Wei: Tsze-kung asked,"Is it possible for a feudal lord to act without the middle way?" The Master said,"It is not possible to engage in it. It's a pity to be abandoned in the middle." Zi Gong asked Confucius,"Can a vassal continue to move forward if he does not follow the right path?" Confucius said,"We can't go on." It's a pity not to follow the right path." This sentence tells us that in life, we need to be vigilant at all times and not go astray from our own track so as to maintain the right direction and motivation to move forward.
Second volume of the second year of junior high school, classical Chinese, all
There were a total of eight classical Chinese articles in the second volume of the second year of junior high school, including the Book with Zhu Yuansi. The specific original text is as follows: Wind and smoke are clean, Tianshan common color. Drifting from the stream, whatever you want. From Fuyang to Tonglu, more than a hundred miles, strange mountains and rivers, the world is unique. The water is pale green, thousands of feet can see the bottom. Fish and fine stones can be seen directly. The rapids are like arrows, and the waves are like running water. Cold trees grow on the mountains on both sides of the river. Against the momentum to compete for the upper position, each other's high and distant; They compete for the highest position, and thousands of peaks are formed. The spring water stirred up the stone, and the sound of the spring water was clear. The birds chirped together, and the singing became a rhyme. Cicadas can turn thousands of times without stopping, apes can cry hundreds of times without stopping. Those who fly high in the sky can rest their hearts when they look at the peak. Those who manage the affairs of the world can only look at the grain and forget to return. It is still dark in the day when the sky is covered by the horizontal branches. The sparse branches reflect each other and sometimes see the sun. This classical Chinese article described the author's boat trip from Fuyang to Tonglu, describing the magnificent scenery of the mountains and rivers and the natural ecological environment.
All the famous questions in junior high school.
I'm not a fan of online literature. I'm just a big fan of novels. I can answer many questions about language and knowledge. Do you have any other questions?
Mathematics questions!
A free proposition in mathematics usually referred to a question with the nature of giving points. The answer was often very basic or common, but it was not easy to find the correct answer. If he did this question wrong, he might fail the entire exam. Therefore, before the math exam, one must carefully examine the questions, grasp the key points and difficulties of the questions, and not underestimate any of the questions.
