The first year of high school in the third year of junior high school came in to help 20

The number of English words in the high school entrance examination is very limited, and there are not many new words. Look at the textbook more and understand all the English words in the book, and there will be no big problem. Listen more, there is no shortcut to this.

You can listen to English songs, practice your listening and relieve your fatigue. Finally, pay attention to the speed of answering questions, many people are slow to answer English questions, which is a loss.

English is actually very simple Master the words 30 words a day and forget it again the next day I suggest you buy a book of English 3500 words Is that good Listening is simpler When you listen to it, just integrate yourself into the language environment I suggest that you should interfere when doing the questions Calm down Don't listen to English songs It doesn't do anything except distract you Essay I suggest prepare more famous sentences It's OK to write the words well Doing English is sure to be good Accurate If you are not sure when you check it, you will not change it.

I didn't speak English well when I was in high school -- you buy more papers for the high school entrance examination and do the second part.

There are many questions in the junior high school entrance examination that can be encountered almost as much as reading In the third year of junior high school, a green basic English requirement will be issued to memorize all the words there Basically, the article can be understood Listening, my personal experience can really be practiced More practice The most important thing is a green book and then composition Composition You memorize the beginning of the classics Generally look at the beginning to give you a grade of ABCD Which grade is completely different The most important thing in the language is actually the composition - take a good look at some of the good writing It's really hard to memorize one or two paragraphs, but when you take the exam, you can only follow his ideas, don't write exactly the same

If you don't have good grades, you don't hurry up and struggle, how can you still have time to wander around the Internet, in the past, you could do well in the exam because the content of primary school was simple, and how could you still think about opportunism in junior high school? I think everyone like you doesn't have to study, just make up for it before the exam. Keep your feet on the ground.

One, two, three, and four are quadratic functions, exponential functions, power functions, and pairs.

One, two, three, and four are quadratic functions, exponential functions, power functions, and logarithmic functions.

The power function is not easy to draw.

The calculation of vector coordinates is to calculate the horizontal and vertical coordinates separately.

abscissa = 2

Ordinate = 2

Vector,

Let k1 and k2 be the slopes of ab and cd, respectively.

k1=(0-1)/(1-0)=-1

k2=(2-1)/(1-2)=-1

k1=k2 Therefore, ab cd

You can also use vectors.

Find the coordinates of the vector ab and vector cd respectively.

It would be nice to prove that their slopes are equal.

Draw a coordinate diagram and mark the points to find abThe slope of cd is fine, and the slope of both of them is equal and parallel.

Find the vector ab, vector ac, vector bc

Category Discussion: AB Vertical AC; AB Vertical BC; AC Vertical BC; 3. Find the value of m in the third case.

y/x = (8-2x)/x = 8/x - 22<=x<=3, 8/3<=8/x<=4

2/3<=(8/x-2)<=2

So the maximum value is 2 and the minimum value is 2 3

I'll give, I'll give you a detailed analysis.
