Those left behind by Qiang Qin's servants will entertain our guests. Please resign and decide! So Mrs. Fife and the guests who knew about it were all dressed in white and sent to Yishui. Grandfather stepped onto Gao Jianli's Jing Ke Song Road, and all the singers wept bitterly. Before the song, it said: the wind is rustling, the water is cooled, and the brave are revived! After generous feather, people are crowned in Jing Ke, and the car is finally done. Since Qin held a thousand dollars, Meng Jiajia, the favorite minister of Qin, first said to Qin: I'm really afraid that Wang Wei dared to dispatch troops and refused to pay tribute to the county minister, guarding the ancestral temple of the first king, fearing that Chen Jin dared to cut down the fan, offering a letter of worship to Yan Dukang and sending it to the court. So he heard Wang Wei's order, and Wen Xi dressed himself in royal clothes, and invited nine guests to see Yan. An envoy took photos and sent them. The poor dagger surprised the king of Qin when he saw that he was holding a dagger in his left hand and a dagger in his right hand. I'm afraid I'll draw my sword in a hurry and put it in my room. Jing Ke drove Zhu away, and the ministers were stunned and at a loss. Qin's attendants hold rulers; All the Langzhibing were summoned by Chen Dianfei's imperial edict, so Jing Ke rushed after the Qin king's pawn, and his hand * * * fought for the doctor Xia, and his medicine bag Qin pawn, anxious to know the left and right, said: Wang negative sword! Wang negative sword! Then he hit Jing Ke and broke his left leg. Jing Ke led him to lift the dagger, lift the pillar of the king of Qin, lift the pillar of the king of Qin, and then hit the pillar of the king of Qin, playing eight pieces of self-knowledge leaning against the column and laughing at the basket. He said: "If you want to rob, you must make too many appointments, and you must behead King Jing Ke for a long time." 5438+0.

After careful consideration, bribing Meng Jia with a large sum of money plays an important role in deceiving the king of Qin to successfully implement the assassination plan. Chen Shaohua calm down, let Qin Wuyang, Qin's fear look aroused Qin Junchen's suspicion. Fortunately, Jing Ke tactfully resolved D.' s loyalty and sincerity, and Jing Ke hoped to capture the king of Qin alive and seek Qin Yan's long-term reward, Dan Tai 13. Jing Ke chased the king of Qin, Qin, and all his ministers were surprised and lost their intention. (4) Reference answer: 10. C (tolerance and forgiveness) 1 1. B(B All prepositions are consistent; A 1 conjunction in 2 adverbs only C 1 preposition uses 2 prepositions to modify the translation and D 1 conjunction list. 12.a (Jing Ke did not yield to power) 13.

You can say goodbye to the teacher now. With a dagger, Qin's death is hard to predict. I want to wait for my friend to say goodbye now, because it's too late. All the guests were dressed in white clothes and white hats to bid farewell to Yishui. Gao Jianli is creating Jing Ke's music and making sad sounds. Everyone is in tears. Jing Ke sang before he went: The wind is rustling, the brave are cold, the relapse is fierce, and the generosity is full of eyes. The hat is off. Jingke's car has never given a generous gift. Meng Jia Meng Jia, Minister of Qin, said in advance: The prince of Yan is really not afraid of the king of Qi. You dare to send troops against the king. You are willing to take the whole people as the king. Like Qin county, you can pay tribute to Qin and ask for a temple. You're not afraid to make a statement. Now I'm going to cut off Fan's head and present the picture of the satrap of Yan State with a swallow in a box. The court will send some cautious people to tell the king to listen to you. You tell the king to listen to you. I'm not happy to wear a royal dress and have a ceremony for nine guests. Xianyang Palace received Yan's envoy. Jing Ke is holding a box with Van Yuqi. Qin Wuyang was afraid of changing his face. His ministers were surprised that Jing Ke left with a smile. Before Qin apologized, he said, I didn't see anything in the far north. I hope the king can forgive me a little, so that I can complete my mission in front of the king. Qin Jing Coe said: As Tu Tu, all the daggers are exposed. Jing Ke seized Qin sleeve with his left hand, and stabbed Qin with his right hand without a dagger. Qin stood up and broke his sleeve. The sword is too tight to carry the scabbard. Jing Ke chased Qin and ran around the pillar. The princes were not surprised. Things suddenly don't want home. They are all rude. According to the Qin law, the palace served the princes and brought some weapons. Armed guards didn't make the temple in an emergency, so they asked Jing Ke, the bodyguard, to go after the Qin family. There's nothing to pay Jing Ke. He only used his hands to fight with Jing Ke, a Qin doctor, and threw his medicine bag at the king of Qin in Jing Ke. He ran around the post in panic and was at a loss. All the officials reminded him that Wang Kuaijian had his back to Wang Kuaijian and his back to the king of Qin, drew his sword and stabbed Jing Ke, cut off Jing Ke's left leg, and Jing Ke was disabled. He raised his dagger and threw it at the king of Qin. He missed the pillar, cut down Jing Ke in Jing Ke, and was wounded with eight swords.

Cloze and reading in English "Ya Feng English" are real questions, which are explained in detail, well-bound, and full of happiness =3= I made 8~9 cloze mistakes, and now there are 1 ~ 2 cloze, which contributes a lot, but remember to record new words in time and fill in the 553 English series, which is suitable for students in national papers to adapt to the questions.

10. The language "Three Steps to Classical Chinese" has innovative and practical classical Chinese materials, which are different from the general ones and divorced from the topic of classical Chinese. Some chapters in it are very useful ~ pay attention to summary ~ remind classical Chinese that there must be an accumulation book, and read it from time to time, otherwise it will be unfamiliar ~

The best training mode 4 High school essential counseling books recommend the strongest inspirational books for the college entrance examination, and Taobao searches for "Butterfly Change of the College Entrance Examination" to buy a round of materials with answers. The round of materials and test papers distributed by our school have no answer analysis, and the materials without answer analysis are particularly liberal arts. If you don't do it, you don't know why it's wrong. What is he doing? 45 sets of star education gold test papers or 38 sets of Tian Li college entrance examination simulation test papers. Mathematics and English literature are the best. Four sets of red, yellow, blue and green papers for star education have been collected since your freshman year. The quality of this paper is very good. Worst of all, you should buy a new curriculum standard for your last class. Star is recommended. I feel that Tian Li's analysis of big problems is not very good. Students with math scores of 50 to 90 can sum up all the questions in the college entrance examination. This book can basically replace your first round of information. With it, you don't have to write a round of information. There are several supporting books behind this book. After 30 minutes, you can choose to fill in the blanks, penetrate the last three volumes of the college entrance examination questions, or make a fuss about Bourne education. I don't recommend making a fuss. It is more difficult to use mathematical formulas. Small and convenient, such as the small-scale test questions between 90- 1 10 of green cartoon mathematics, you can do one after the first period. At this stage, it is mainly recommended to make a set of papers that must be brushed in the college entrance examination. After buying 12 sets, the previous ones are not as good as Tian Li's 38 sets and Tianxing's 45 sets.

Alliance of a hundred schools, which emphasizes the practice of making small problems crazy. Can stars practice moderately? Although there are many papers on the market, you should never do pheasant papers and those papers improvised by star Tian Li. For example, the quality of the first gold test paper is generally low, and the mathematics is between 120 and 130. At this time, you should have your own understanding of whether the math paper is right or not. At this stage, you should not only make a set of papers, but also realize the key. Then there are many types of advanced books. 5 New product list of teaching materials and supplementary reference books for senior high schools: one question and one lesson: appreciation of good questions in senior high school mathematics; perspective of five-year college entrance examination questions: preparation manual for senior high school mathematics league; analysis of typical examples of problem-solving methods and skills in senior high school mathematics; history lesson for American special-grade teachers: cultivation circle of critical thinking and its application ideal tree; questions must be brushed in the college entrance examination; and a higher and better review manual for NMET mathematics should be strengthened through different types of questions. What guidance book is suitable for the new NMET 6 English translation and abstract writing with a score of 600? 1. physics: higher and better NMET physics (note NMET and self-enrollment version, not competition version), very good, suitable for students with good foundation. But if time is running out, don't look at it and concentrate on doing the college entrance examination questions, which was used to open up ideas in the early stage.

2. Mathematics (second round, teaching method) is still excellent in Zhejiang University. Many people should know "The Way of Thinking in High Mathematics", which is quite good. It mainly focuses on the finale of the method, but if you look at it selectively, it is a bit difficult without the basis of mathematical competition. There is also a series of classic topics selected by Zhejiang University, with high quality and large number of questions, which can be used to overcome weak chapters ~3. Mathematics (recommended for high school students in Grade One and Grade Two to synchronize their homework) "Have you really mastered the mathematics in the college entrance examination?" In short, this series is divided into four books, covering all chapters except trigonometric functions.

The topic goes from shallow to deep, the method of example is very good, and the language is particularly vivid. The amount of questions is relatively large, and brushing questions is also acceptable.

The most important thing is to help you think. Suitable for general courses "May 3rd" ~ 4th. The purple version B is recommended, with a large number of questions and moderate difficulty, while the red version A has a small number of questions and a large number of basic questions, so consider it at your own discretion ~5. General course (I recommend a fixed number of copies every week, I do Math 2, Physics 2, Chemistry 1 every week) "Gold Test Paper 45", I think it is better than Tian Li 38 ~ the title is quite good.

But pay attention, don't brush the simulation questions of Chinese and biology, it's useless, and the questions are very poor. 6. Biology and chemistry (one round) "Ten-year college entrance examination", recommending materials of biology, chemistry and pure brush questions, which are real questions, can help you build a knowledge network quickly, remember to read the answers carefully and record mistakes and knowledge points. 7. Physical Chemistry "Multi-functional textbook Physics or Chemistry" is suitable for top students who want to improve in senior one and senior two, but senior three dogs can't afford it.

You don't have to brush every question, otherwise it will take too much energy. There is a difficulty level on it, so just pick and write ~8. The pamphlet "General Examination Research (Round)" published in January has many little knowledge points that people are overwhelmed with, so we must do it seriously and remember it carefully! Sure! Really vomiting blood is recommended, especially good. 9. Gestalt and reading in English "Elegant English" are real questions, which are explained in detail, bound and full of happiness! I made 8~9 cloze mistakes, and now there are 1~2 cloze, which makes a great contribution, but remember to record the new words in time ~ the short cloze in the English series of May 5 and May 3, which is suitable for students in the national paper to adapt to the questions ~ (But there are still many mistakes, so students who care about this buy Qu Yixian Series, and the questions are the same) 5438+00./kl

4. Let the rank of the third-order real symmetric matrix A be 2, λ 1=λ2=6 is the double eigenvalue of A, if α 1=( 1, 1) t (1) because λ1= λ 2. 1, 0)T, α2=(2, 1, 1)T is a linear independent eigenvector of 6. Since the rank of A is 2, another eigenvalue: λ3=0, let its corresponding eigenvector be α = (x 1, x2. That is, x1+x2 = 02x1+x2+x3 = 0, and the basic solution system is: α = (- 1, 1) t, so the eigenvector to which λ3=0 belongs is: kα =1. (2) Let the matrix: P=(α 1, α2, α3), then: P- 1AP=6 6 0, ∴A=P6 6 0 user 20 17-. And the judgment of linear correlation or irrelevance. We need to know the relationship between the eigenvectors of a real symmetric matrix and the method of calculating the matrix when we know the eigenvectors and eigenvalues of the matrix. The teacher commented on this topic: the solution of eigenvalue and eigenvector of matrix. Test comments: It should be noted that for real symmetric matrices, the eigenvectors belonging to different eigenvalues are linearly independent and orthogonal. Scan and download QR code? 2020 ?

5. Let A be a third-order real symmetric matrix and satisfy A2+2A=0. It is known that the rank r (a) of A is 2. (1) Find a (1) Let λ be an eigenvalue of A, then: α = λ α, (α≠0), then: (λ 2+λ 2) α = 0, from α≠0, λ 2+λ 2. Because a is a real symmetric matrix and must be diagonalized, r(A)=2, so the diagonalized matrix is:? 2 ? 2 0=B So: all eigenvalues of A are λ 1=λ2=-2, λ3=0. (2)∵A+kET=AT+kE=A+kE, that is, A+kE is still a real symmetric matrix, and the real symmetric matrix A has a invertible matrix P such that P- 1AP = 2 k? 2 k, in order to make the matrix A+kE a positive definite matrix, only k-2 >; 0 and k>0, namely: k>2.
