How old is the sampling test paper, mathematics test paper and answer test paper in Xicheng District, Beijing?
The last page of the seventh grade of mathematics learning exploration diagnosis in Xicheng District of Beijing has the answer, but I don't know if there is a seventh grade. If you lose it, I suggest you go to the bookstore near the north gate of Taoranting. Now the school is about to start. Many parents buy counseling books there, and there is a small window next to it to buy cooked meat products.
Xicheng District, Beijing 08-09 Primary School Grade Three Final Examination Paper, go to Flat Peach Beijing Education Navigation to find it.

15. Examples of answers: ① fierce; 2 self-selected teaching materials; Interesting reading; 3 modify the composition.
Scoring standard: **4 points. ① 1; ②2 points, 2 points, each point is 1 minute; ③ 1.
16. For example, the answer is: "Disappointment" Content: I have been away from my teacher for nearly 50 years, and I have never heard from him, and I don't know the recent situation of my teacher.
Content of "admiration": xu teacher is very talented, has a high level of teaching and is responsible for students.
Scoring standard: **4 points. ***2 items, 2 points for each item. "I have been away from my teacher for nearly 50 years" is 1, "I haven't heard from you, I don't know how the teacher is doing" is 1. "Very talented", ("high teaching level" or "unique teaching style" 1, "responsible for students" 1. ("Very talented, high teaching level" will get 1 point if you answer "Choose your own textbook, read it interestingly and correct your composition uniquely". A little less does not score. )
17. Examples of answers 1: The author first wrote about Mr. Xu's strange appearance and behavior. In the composition class, he called me "What are you? I will take a look at you to the end "to highlight his ferocity. He also compiled his own selected teaching materials, which were very interesting to read, and corrected my composition with a big brush, which benefited me a lot, highlighting his highly educated and serious and responsible attitude towards students. The full text adopts the writing method of "emphasizing before suppressing" (comparing before and after), which makes an ordinary Chinese teacher vivid and unforgettable.
Example 2: The author writes about xu teacher's appearance, describes it with portraits, writes about his class, and describes it with language and actions, highlighting xu teacher's "fierce" characteristics; When revising my composition, he described it in detail, which shows his seriousness and responsibility. The article uses a variety of characterization methods to make xu teacher's image vivid and unforgettable.
Scoring standard: **7 points. 2 points for writing, 2 points for combining the content of the article, 2 points for analyzing the characteristics of characters, and 1 point for language expression (words exceeding 140 will be deducted 1 point).
(2)(* * 8 points)
18. Key points: If "everything disguised as nature" is deleted, ① the meaning of "insect mimicry" is unclear. (2) The specific method of "hiding yourself, scaring off the enemy, or facilitating your foraging" (or "getting a chance to survive") is not clear.
Scoring standard: **2 points. ***2 reasons, each of which is 1.
Delete ①, and you will not know the meaning of "insect mimicry". ② The method of "hiding yourself and scaring off the enemy" is not clear.
Scoring standard: **2 points. ***2 reasons, each of which is 1.
19. Material 1: Insect mimicry belongs to aggressive mimicry. Because aggressive mimicry is the mimicry of other creatures in order to get close to aggressive objects. Here fireflies imitate other kinds of fireflies to achieve the purpose of hunting.
Material 2: Insect mimicry belongs to Miller mimicry. Because this mimicry is a mimicry phenomenon in which two inedible species with warning colors simulate each other. These two kinds of North American monarch butterflies are brightly colored poisonous butterflies. They imitate each other and fool predators.
Material 3: Insect mimicry belongs to Bates mimicry. Because this mimicry is that food species simulate poisonous, spiny or unpalatable species to escape from the enemy. The flower-visiting fly is non-toxic. It imitates the inedible stinging bees to protect itself.
Scoring standard: **6 points. ***3 kinds of materials, 2 points for each material. Point out that the type is 1 and briefly describe 1.
(3)(* * 8 points)
20. A: ① Tolerance transcends the boundaries of countries, languages, nationalities and civilizations;
(2) tolerance, is the moral quality that the people of the earth have and praise.
Scoring standard: **2 points. ***2 points, each point 1 point.
2 1. Answer: A 3 B 2 C 1
Scoring standard: **3 points. ***3 null, each null 1 min.
22. answer example 1: it can be seen that not everyone can be tolerant; Gou Jian, the King of Yue, knew how to endure, but did not know how to endure. Although Han Xin was humiliated by cheating, he was able to "let bygones be bygones", which is a kind of accomplishment and a reflection of the realm.
Example 2: Obviously, Han Xin's practice can better reflect the accomplishment and realm of being a man than Gou Jian's, and this tolerant attitude can also be respected by later generations.
Scoring standard: **3 points. The viewpoint of care is 1, the relationship between reflection material and viewpoint is 1, and the contrast material is 1.
