It shows that students are often confused about the relationship between quantity and quantity. But for language problems, if we distinguish the difficulties of topic language in more detail, we will find that it can be roughly divided into three categories: First, English vocabulary is not.
Enough; Second, the mathematics vocabulary is not enough; Third, the quantitative relationship is unfamiliar.
The mistakes caused by the first question type are mainly reflected in the fact that candidates don't know the meaning of some English nouns, so they have no idea what the topic describes or how the process is carried out. For example, the following example:
Example 1: A quarter, a 10 cent, a 5 cent and a 1 cent are put in a box.
Take out the box and put it back before taking out the second coin. How many people?
You can draw two coins in different ways, so that the sum of the values of the two coins
Is the coin at least 25 cents?
A.9 B. 7 C. 6 D. 5 E. 4
How many ways are there? The sum of the two coins is at least 25 cents. If students don't know that 25 cents, 10 cents, 5 cents and 1 cent correspond to 25 cents, 10 cents, 5 cents and.
1 minute, this problem is very difficult to do. To solve this problem, students need to accumulate more words. As far as mathematics is concerned, students should pay special attention to some knowledge modules that often produce application problems, and the surrounding words are very important.
For example, the words related to gambling in probability problems, the head and tail of coins, dice and dice, and the poker colors such as spades, hearts, diamonds and clubs.
The problem of the second kind of math words must be completely solved by students in the early stage of preparing for the exam. The way to review is to recite the math vocabulary list carefully. In the process of memorizing, we should focus on memorizing the mathematical meaning of words, preferably.
Knowledge review can be integrated into it, paying attention to memorizing plural forms and polysemous words. For example, the complex form of a vertex is a vertex and the complex form of a radius is a radius.
Example 2: Which of the following fractures is the equivalent decimal number A?
Terminate the decimal system?
A.b . 10/ 189 c . 15/ 196d . 25/ 144 e . 39/ 128
This question contains a lot of mathematical vocabulary. The question means which of the following fractions is a finite decimal. In which termination
Decimals Many students express finite decimals unclear. Because GMAT can't use a calculator, how to find the answer quickly is also the ability we need in GMAT math exam, because whether.
Because the finite decimal is determined by the denominator, the simplest fraction containing 3 or 7 in the denominator must not be a finite decimal, so A, B, C and D can be eliminated quickly, so choose E. ..
The third language problem is that some phrases are not clear to students about the expression of quantitative relations. For example:
Example 3: There are three types of pencils, J, K and L, and the prices are $0.05, $ 0. 10 and $0.25 respectively.
Respectively. If a box of 32 such pencils costs a total of 3.40 dollars.
If there are twice as many K pencils as L pencils in the box, how many J pencils are there?
Is it in the box?
a . 6 b . 12 c . 14d . 18 e . 20
For a with "twice as much as"
B "this sentence pattern, students usually don't know whether it is A=2B or 2A = B. Here, A=2B is the correct understanding, so K=2L and J=32-3L can be expressed. Using the total price, we can get a one-dimensional linear equation, calculate L as 6, and get the answer J= 14.
