1 The following sentences can be used in aspect 20

In the description of the following three sentences, the correct one is ().

a.The three statements are equivalent to each other.

b.The three statements are in a mess of 2?With 3?Equivalent.

c.1??. in three statementsWith 2?Equivalent.

d.Each of the three statements is not equivalent.

Correct Answer: a

A mistake is that there are no units in the scale.

B is false, the older you are, the greater your weight does not necessarily be.

C is wrong, and there are other relationships to choose D

A has an extra ruler, and both b and d have an extra example, and c is a pair.

1. Scale cannot be said to be a unit.

2. This statement is that the older the older you are, the heavier you are, or the younger you are, the younger you are, which is obviously incorrect.

Three is also a functional relation, but obviously not proportional or inversely proportional (linear), and the fourth term is correct.

A mistake is that there are units in the scale.

B is wrong, it may be light when it is old.

c not necessarily, it may be the same d pair.

The outer angle of the B triangle must be greater than the inner angle adjacent to it; If it is an obtuse triangle, it is not true.

If two of the inside angles of a triangle are less than 60°, then it must be an acute triangle. It can also be a right-angled or obtuse triangle.

The difference between the following three sentences is (from far to near, from thick to fine, from slight to detailed, from the whole to the part, so that the character image gradually enriches and clarity with the observation and feeling of "me"), and its purpose is to (grasp the characteristics of Lu Xun's "thinness", highlight Mr. Lu Xun's noble quality and great personality, and express the author's nostalgia for Mr. Lu Xun. ）

a "Thirty-one years of teaching, peach and plum all over the world. This sentence means that the students give the teacher a lot of peaches and plums.

b "There are several fights in life! This sentence is very pessimistic.

c "Oh, children in the mountains, there is a diligent childhood in the back" This is the central sentence of the article, praising the child's industrious quality.

d The phrase "do not take the good as small and do not do it, and do not take the evil as small" means that although the good is small, it is necessary to do it, and the bad thing is small and cannot be done.

e Xiao Ming's math score is very good, because Xiao Ming's grandfather is a college math teacher.

Answer] B [Answer Analysis].

Sentence types can be divided according to tone, such as: declarative sentences, interrogative sentences, exclamation sentences, imperative sentences, etc. It can also be divided according to the structure, such as:

Subject-predicate sentences, macrona subject-verb-object sentences, definite subject-verb-object sentences, and so on. The four sentences in this question are all declarative sentences in terms of tone, but from the structural point of view, the main components of the three sentences a, c, and d are all subject-verb-object forms, and they are single sentences. Option B, on the other hand, is two clauses (conditional clauses) with two sets of subject-verb-object structures.

Therefore, option b is the correct option.

c This is a problem of repetition of words. "Pass" and "make" are repeated.

Correct answer c

The language disease of other sentences is that the preposition is used indiscriminately, which is the sentence without a subject.

c is correct, but the comma should be removed.

a From ......Makes Repeated.

b d by ......Makes Repeated.

The correct one is c. Remove the comma in the middle.

In sentence d, the word "make" should be deleted.

c, all other sentences belong to the absence of a subject.

The answer is a, swapping the conditions and conclusions of a proposition gives its inverse proposition, so every proposition has an inverse proposition. As for whether this inverse proposition is unique, it is worth considering.

In the study of specific problems, a proposition must have its research direction, and after defining the research direction of the original proposition, an original proposition has a unique inverse proposition. Sometimes it's not that the original proposition is poorly formulated.

A to say a sentence in reverse, of course, is possible, therefore, the proposition can always be said in reverse, that is, there must be an inverse proposition.

The original proposition is the same as the inverse negative proposition, so c d is wrong.

As for b, the so-called theorem must be true [derived from the axiom], but a theorem is like a proposition, it must be said the other way around, for example, "two straight lines are parallel, the same angle is equal" in turn is "the same angle is equal, two straight lines are parallel", but for the "theorem in reverse" he must meet the condition of being definite, that is, it must be true, but not all theorems are true in reverse! [I can't think of a counterexample for a while.,I'm sorry] So,That's not right.。。。

a。The law is necessarily true, but the inverse law is not necessarily a law! The original proposition and the inverse proposition are equivalent!

A bar. bIt is common sense that there can be an inverse law in any law.

c should be the inverse of which the proposition is also true.

The proposition of d negative is also false.

Choose A, why bother so much! Give it to me.

A b theorem has no inverse theorem common sense.

The proposition that c and d are the inverse of the negative is the same as the truth or falsehood of the original proposition.
