Theory A5 Unified State Exam in Russian. Syntactic norms in the Unified State Examination in the Russian language: analyzing task A5

TASK A5

We introduce students to the type of task:

Indicate the sentence with a grammatical error (in violation

syntactic norm).

Let us remember that syntax regulates the construction of phrases and sentences. We draw the children's attention to the fact that there are NO punctuation errors in this task (for some reason, children often think that the commas are placed incorrectly).

When solving this task, you need a “feeling” of the language, but there are some tips that can help even those for whom Russian is not their native language:

1. If there are quotation marks in a sentence, check the form of the name of something that is in quotation marks. There are 2 options here:

  • If a generic title (book, newspaper, magazine, painting, etc.) precedes the quotation marks, the title in quotation marks must appear in Im.p. For example, the novel “Eugene Onegin”; painting “Autumn”; song "Dubinushka".
  • If there is no generic name before the quotation marks, the name in quotation marks is declined. For example, in “Eugene Onegin”; in "Autumn" by Levitan; in "Dubinushka".

2. If the sentence contains a participle, check its form (ending). To do this, we ask a question from the word being defined to the participle. For example, “there were a lot of guys (who?) came to the forest.”

3. If the sentence contains derivative prepositions “according to”, “thanks to”, “despite”, we check the form (ending) of the noun that comes after this preposition. These prepositions are combined with nouns in Dat.p. (to whom; to what?).

4. If the sentence contains the constructions “all who...”, “those who...”, “the one who...”, etc., it is necessary to check the agreement of the subject and predicate (singular/plural) in the main and in subordinate clauses.

All, who watched at him, no could miss…

plural units units units plural

5. If a sentence contains homogeneous members of the sentence, connected by the conjunction “and”, followed by a common dependent word(s), it is necessary to check whether the first homogeneous member of the sentence is consistent with this common dependent word. For example, in the sentence “we hoped and believed in victory,” the first homogeneous member of the sentence “hoped” does not agree with “in victory,” so there is a grammatical error in this sentence.

6. If the homogeneity of concepts is violated, i.e. Words from different parts of speech are used as homogeneous members of the sentence. For example, “I love drawing and painting”;

7. If in a sentence homogeneous members are connected by double conjunctions “not only - but also”, “as – so and”, “if not – then”, it is necessary to check whether the homogeneous members of the sentence stand immediately after these conjunctions. For example, in the sentence “We waited Not only Waving, but also Vanya” the conjunctions are correct. If we change the place of one of them: “We Not only were waiting for Masha, but also Vanya,” a grammatical error will appear in the sentence.

8. It is unacceptable to violate the uniformity of the syntactic elements of a sentence. For example, in the sentence “Ivan, who studied in the 9th grade and took part in the competition, ...” an error was made. !!! The participial phrase and the subordinate part of a complex sentence cannot act as homogeneous syntactic elements.

9. You cannot mix direct and indirect speech. It is unacceptable to use the pronouns “I, WE, YOU, YOU” in the subordinate part of a sentence in indirect speech. For example, “Dima admitted that I I’m not ready for class today.”

10. The prepositions “in moderation, during, in continuation, by force, in conclusion, in the form of, for a reason, like” are combined with the gender case (whom? what?).

11. The prepositions “like, contrary” are combined with the Datum case (to whom? to what?).

For solving A5 Unified State Exam problems in computer science, you must be able to execute algorithms written in natural language. It is also necessary to have.

For example, consider solving problem A5 in computer science from training work 2 from 02/15/2013.

The teacher suggested that the children practice using hexadecimal numbers and play such a game. It presents children with three hexadecimal digits, in non-ascending order. Students must first find the difference between the first and second digits, then the difference between the second and third digits. Both differences must be written as decimal numbers. Then these numbers are written one after another in non-increasing order (the right number is less than or equal to the left).

Example. Initial numbers: A, A, 3. Differences: A - A = 0; A - 3= 10 10 - 3 10 = 7 10. Result: 70.

1) 131 2) 133 3) 212 4) D1

Solution:

The 4th option does not suit us for the reason that the number D1 is not decimal. That is, it contradicts the conditions of the problem in the part “Both differences must be written as decimal numbers.”

Let's consider the 3rd number - 212. This number can be represented as 2 and 12, or as 21 and 2. According to the condition, the final numbers are written in non-increasing order - which means you only need to consider the option 21 and 2. The condition says that the original numbers - hexadecimal. That is, in the decimal number system these are numbers from 0 to 15. It is clear that it is impossible to select such numbers (from 0 to 15), the difference of which will be equal to 21. This option is also not suitable.

The second option, by analogy with the first, we will imagine as 13 and 3. The number 13 can be obtained by subtracting 2 from 15, subtracting 1 from 14, or subtracting 0 from 13. But after that we must subtract more from the subtracted (2, 1 or 0) some number and end up with 3. But this is impossible. The option is incorrect.

Let's imagine the first option as 13 and 1. But here everything is correct. 13 can be represented as 15 - 2, and 1 = 2 - 1 - the original numbers could be like this - F, 2, 1. This is correct option.

Let's consider solution second option:

The teacher suggested that the children practice using hexadecimal numbers and play such a game. It presents children with three hexadecimal digits, in non-ascending order. Students must first find the difference between the first and second digits, then the difference between the second and third digits. Both differences must be written as decimal numbers. Both differences must be written as decimal numbers. These numbers are then written one after another in non-decreasing order (the left number is less than or equal to the first).

Example. Original numbers: B, 3, 3. Differences: B - 3 = 8 10 ; 3 - 3 = 0. Result: 08

State which of the following character sequences might be the result.

1) 122 2) 212 3) 313 4) 3A

Solution:

Option 4 is not suitable because 3A is not a decimal.

Let's imagine option 3 as 3 and 13. 13 can be represented as 15 - 2 (or 14 - 1), but then we will need to subtract an unknown number from the number 2 (or 1) and end up with 3. This is impossible.

Let's imagine the second option as 2 and 12. Then 12 can be represented as 15 - 3, and 2 = 3 - 1. Everything works out - this is the correct option.

The first option is incorrect. Let's imagine the number 122 as 1 and 22. It is clear that by subtracting two numbers, each of which is not more than 15, you cannot get 22.

Let's consider solving problem A5 demo version of the Unified State Exam in computer science 2013

The machine receives two two-digit hexadecimal numbers as input. In these numbers, all numbers do not exceed the number 6 (if the number contains a number greater than 6, the machine refuses to work). Using these numbers, a new hexadecimal number is constructed according to the following rules.

1. Two hexadecimal numbers are calculated - the sum of the most significant digits of the resulting numbers and the sum of the lower digits of these numbers.

2. The resulting two hexadecimal numbers are written one after another in ascending order (without delimiters).

Example. Initial numbers: 66, 43. Bitwise sums: A, 9. Result: 9A.

Determine which of the proposed numbers can be the result of the machine.

1) 9F 2) 911 3) 42 4) 7A

Solution:

Let's consider the first option. Let's imagine the number 9F as 9 and F. Since the original numbers do not exceed 6, it is impossible to find numbers whose sum will be equal to 15 (F 16 = 15 10). This is the wrong option.

Since the original numbers do not exceed 6, their maximum sum will be 6 16 + 6 16 = C 16 = 12 10, which is less than 11 16 = 17 10. Those. the case is similar to the previous one and this is also an incorrect option. In addition, the sum of two hexadecimal numbers not exceeding 6 cannot be two-digit.

The third option is not suitable, since the numbers are written in descending order, which contradicts the condition.

We find that the correct option is 4. Let's check this. Let's imagine the number 7A as 7 and A. Now it is easy to imagine 7 16 as 3 16 + 4 16, and A 16 as, for example, 5 16 and 5 16. Then everything is correct - the two original numbers could be 53 16 and 54 16. If we now fulfill the first point of the condition and add up the high-order digits, we get 5 16 + 5 16 = A 16 , and the sum of the low-order digits is 3 16 + 4 16 = 7 16 and then, after fulfilling the second point of the condition, we get the number 7A 16 . The correct option is the fourth.

The Unified State Exam in the Russian language contains in the first block of tasks a question, the wording of which is not entirely clear to most graduates. The test taker must determine in which of the sentences a grammatical error was made, namely, syntactic norms were violated. In some cases, the answer is obvious, and the graduate intuitively chooses the answer, relying on his “unconscious” knowledge of the language. It is most difficult for those children for whom the language is not native, and they started learning it later than others.

About 20% of those tested fail to cope with this task in one way or another. So, in order to protect yourself from this error in the easiest block of the Unified State Exam - Part A, you need to decide what syntactic norms are. And to do this, you must first remember the broader basic definition.

What is syntax and what do language norms have to do with it?

To answer this question, we need to look at the structure of the language itself. It most closely resembles a multi-layer cake. It contains several layers - sections, the knowledge of which must fit tightly together in the student’s head so that he sees the overall picture. That is why, starting from the 5th grade, the subject is studied in stages. Before the seventh grade, as a rule, children become acquainted with morphology - the section on parts of speech. In high school, syntax is studied in more depth. Naturally, other sections (phonetics, vocabulary, stylistics, etc.) cannot be ignored. But without knowledge of these two “pillars” - morphology and syntax, it is impossible to understand grammar.

The laws according to which words are combined into meaningful linguistic segments are considered in syntax. Sentences and phrases do not appear if the units of which they are composed are sketched out in random order. In order to express a certain thought, we all unconsciously use certain linguistic laws. Each of us, while still a preschooler, mastered the bulk of these rules. For example, that the character in a sentence is most often indicated by a word in the nominative case. Long before the child is explained what declination is, he is already actively using it: “Mom, buy me a toy!” Naturally, he does not understand that he used the word “toy” in the indirect case. This happens because speech and its norms are copied by the baby from the conversations of others. Nevertheless, as soon as the child constructed his first sentence, he began to use syntactic norms. These are precisely the same laws that strictly regulate the rules for constructing sentences, as well as phrases.

The most “inconspicuous” errors in task A5

It is quite difficult to fit a list of all the laws of combinability of words in sentences within one article. But let's look at the most difficult cases. Let's start with concepts such as coordination and management. In the Unified State Exam tests in the Russian language, many do not see an error in this option:

  • Andrey waited all evening and called his girlfriend.

In this example, syntactic norms associated with control are violated. The first of the homogeneous predicates “waited” does not fit the word “girlfriend”. According to the linguistic norm, both verbs in this case must control it. If this does not happen, then it is necessary to rearrange the phrase so that each predicate is combined with a word in the appropriate case. Pronouns help us with this:

  • Andrey waited for his friend all evening and called her.

Another difficult case of management is the correct use of prepositions. Some of them, especially derivatives (thanks to, despite, according to, etc.) are appropriate to use only with words in the dative case. Others, for example “during”, “in continuation”, “in conclusion”, are combined only with R.p. The form of the preposition “on arrival” generally needs to be remembered. The form, somewhat exotic for modern conversational practice, is the only correct one. Grammatical errors are skillfully hidden in the following sentences:

  • Everyone who could went home.
  • Those who love to read have a good imagination.

In these complex sentences, the word “who” is combined with a plural verb. But the syntactic norms of the Russian language indicate to us that in this case a singular verb is required. The rating of the most “inconspicuous” errors includes an incorrect combination of a verb and a noun. Such cases are numerous. But the most common options are:

  • It is difficult to distinguish parts of speech from words that are spelled the same.
  • Maria said she would miss us.

In the first case, the verb “to distinguish” requires the construction “what from what.” In the second, the form of the pronoun “us” with the verb “to miss” is used incorrectly. That's right: miss us. Naturally, not all syntactic norms require careful study. But paying attention to them and repeating the main ones when preparing for the exam is completely worthwhile.

1. General information

Difficulty: basic.

Approximate solution time (for those who will perform part 2): 2 minutes

Subject: Algorithms and programming

Subtopic: Analysis of the algorithm in natural language

What is checked: Ability to formally execute an algorithm written in natural language. The ability to analyze the many possible results of an algorithm, the many input values ​​leading to a given result.

Comment. A special case of executing the algorithm is checking the truth of a condition.

General view of the task:

An algorithm is described. An example of how the algorithm works for a certain set of input data is given: input data, result, possibly intermediate values.

4 objects are given (numbers, words, etc.).

Examples of questions:

1) Determine which of the given objects can (cannot) be the result of the algorithm.

2) Determine which of the given objects can (cannot) lead to a given result.

Comment. If we impose additional conditions (smallest, largest, etc.), then instead of the task of the format of part A “to indicate who belongs to a given set,” we get the task of the format of part B - to indicate the (only!) element of the set that satisfies the additional condition.

2. Example from the demo version

2.1. The task.

Problem 2012-A5-1.

1. Three numbers are calculated - the sum of the highest digits of the given three-digit numbers, the sum of the middle digits of these numbers, the sum of the lower digits.

2. The resulting three numbers are written one after another in descending order (without separators).

Example. Original three-digit numbers: 835, 196. Place-wise sums: 9, 12, 11. Result: 12119

Determine which of the following numbers could be the result of the machine.

1) 151303 2) 161410 3) 191615 4) 121613

2.2. Solution sketch.

The sum of two single-digit numbers can be either a single-digit number (from 0 to 9) or a two-digit number - from 10 to 9+9=18.

Since all four given numbers are six-digit, all intermediate sums are two-digit. In order for a 6-digit number to be the result of the algorithm, it is necessary and sufficient that its constituent two-digit numbers satisfy the following conditions:

a) they are all in the range from 10 to 18;

b) each next (from left to right) number is less than or equal to the previous one.

Let's consider the numbers indicated in the condition.

1) Doesn't fit. The third pair starts from zero (condition a) is not met)

2) OK. Possible initial three-digit numbers: 875 and 875, 999 and 751, etc.

3) Not suitable. The first pair is equal to 19 (condition a) is not met)

4) Doesn't fit. The second pair is greater than the first (condition b is not met))

A. Strong students .

1. Most likely, they will solve this problem anyway.

2. If not, draw their attention to the key points:

Dividing a six-digit number into pairs;

Which pairs are impossible (19 or more, as well as those that start from zero), it is better if the students themselves formulate these conditions.

3. Come up with your own approaches and try them. J

B. Not so strong students .

1. The first (perhaps the main) difficulty is the condition of the problem itself. Have students run the described algorithm for several inputs. Make sure everything is done correctly.

2. Invite students to come up with a pair of three-digit numbers for a given six-digit number that lead to this result (the problem must be solvable). Offer to come up with several more pairs that lead to the same result.

3. Have students come up with a number that could NOT be the result of the algorithm. Even if they don’t come up with anything, it will help them understand your explanations.

4. Point out to students that six-digit numbers are clearly divided into three two-digit numbers.

5. Find out with your students which pairs are impossible (19 or more, as well as those that start from zero); it is better if the students themselves formulate these conditions.

6. Consider the four given numbers in turn. If a student has difficulty with a certain number, ask the student to come up with a pair of three-digit numbers that lead to the given answer.

7. Come up with your own approaches and try them. J

1. Read the problem statement. Try to come up with conditions that are necessary and sufficient for an object to be the result of the algorithm (for problem 2012-A05-1 these are conditions a) and b)). At worst, formulate the necessary conditions; it is not necessary to prove sufficiency in general terms. If you couldn’t come up with the necessary conditions, don’t spend a lot of time on it (no more than 1 minute). Start looking at candidate objects.

2. Consider each candidate object in turn. For each object, try to come up with input data that gives the output of this object. If it works, the problem is almost solved (see point 3). If it doesn't work, try to prove that it's impossible. If proven, we cross the object off the list of candidates and move on. If not, then we will return to this object.

3. What to do if you find an object that satisfies the conditions of the problem. It is better to look at other objects and make sure that they do not meet the conditions. If this doesn’t work out, you can find your mistake and fix it.

4. What to do if it was not possible to cross out all objects except one, and for this one to prove that the condition is met for it. If among the remaining ones there is exactly one object for which you can prove (or are simply sure) that the condition is met, choose it. If there are several or none of these objects, you will have to guess. Good luck!

Comment. Similar considerations apply to many Group A problems. See TacticA.doc.
