I have a few very important questions, I will submit the form to the teacher in the afternoon, can y

I'll give you my personal opinion.

I think that compared with foreign films, most domestic films focus on the box office first, and there are also many aspiring directors who make literary films, but the general response is that most audiences can't understand literary films, or don't like to watch them. For example, Jiang Wen's "The Sun Also Rises" or Wang Baoqiang's "Hello, Mr. Tree", of course, it is nothing more than that many people can understand it, and the evaluation is also high. They paid attention to the connotation of these movies, but the response was not large, and the lack of response meant that there was no box office, and no box office led to the inability to recover the money invested.

Economic society, now I think many investors will not always contribute for free, they want the box office, they want profits. So these ** are no longer favored by them, they like to make money quickly, like box office, you can also say that American blockbusters also pay attention to the box office, however, American blockbusters often inject a lot of elements in the process of focusing on the box office, stunts, stars, and of course, there is also a good story structure, we know that many American blockbusters have a good response, but the box office may not be recovered, such as the "Lord of the Rings" series, because of the huge investment. There are similar movies in China, Kai Ge's "Wuji", I have something to do, write this first, and then add it when I come back.

It's not just [very] important! It's [crucial] that matters!

Mentors are like the biological parents of graduate students! You will be in control of the content and direction of your research and whether you will be able to graduate successfully!

In short, the life and death of graduate students are in control! Graduate students are mainly engaged in research work under the guidance of their supervisors!

Therefore, the two most important criteria for selecting a tutor are: 1. High academic level; 2. Good character.

It depends on what school you are in, and first-class school tutors are relatively important; However, the more powerful the tutor, the less time he has to deal with you, and the tutors in colleges and universities are busy pulling projects to make money. Self-effort is the most important thing, and you can't revolve around the teacher.

When choosing a tutor, you must understand the situation of each tutor, and you must choose a high academic level, which will be introduced by the general school. This is important for a few years of your graduate career.

Following this kind of tutor is like getting on the high-speed train, and the scholarship is soft.

Of course, there are also those who have no relationship with the admission.

None of these examples are very important to you, because there are no wonders in the world.

It's important to work harder on your own.,In addition, make good use of the resources at hand haoyun 200 (contact ta) yourself.,If the tutor is nothing.,Recommend it and don't use lyx396529 (contact ta) I contacted it myself.,Although my master's supervisor is also more powerful.,But I changed directions.,And then there's if you're in this field.,As long as you have a good background, you don't have to deliberately recommend.,But it's better to recommend yuyu98412 (contact ta) The main thing is to rely on yourself to contact the tutor, of course, the tutor recommendation is better!!

That rubber ball is called an ear blowing ball. This ear blowing ball is equivalent to a pocket leather tiger, which is used to blow soot, pinch it to exhale, release and inhale.

The surface of the watch parts will have seven colors under the sun, because the surface of the watch parts has a pattern, and the sunlight will scatter on the pattern, which will form seven colors, just like the sunlight shining on the broken glass, and has nothing to do with the ear blowing ball.

The air mainly blows away the dust.

I'll give you a forum, there are a lot of experts and posts.

You can check it out.

Look, love cousins.

Conclusion: The value range of a is [-3 2,12].

Method 1: Function in question: f(x)=-ax 3+(a-3)x

then f'(x)=-3ax 2+(a-3) and f(-1)=3,f(0)=0,f(1)=-3

It is obtained from f(-1)=3, f(0)=0, f(1)=-3 and cubic function image features.

A is desirable in only two cases: (1) f(x) is single minus on [-1,1]; (2) a>0,f(x) has a minimum value at (-1,0) and is greater than or equal to -3.

1) f(x) is subtracted on [-1,1], i.e., there is f'(x)<=0

a=0: f'(x)=-3<0, a=0 is preferable.

A<0: Only f'(1)=-2a-3<=0 solution -3 2<=a<0 is desirable.

A<0: Only f'(0)=a-3<=0 when solving 03 (0=-3

That is, (a-3) (1 3-1 a)<=9 2 is solved to a<=12 (the equation corresponding to this inequality is more difficult to solve, and can be solved by commutation).

At this point, 3=-3

i.e. a(x 2+x)>=-3

A=0: a(x 2+x)>=-3 true, a=0 is desirable.

a<0: -3 a>=(x 2+x) and the right range is [-1 4,2).

That is, there is -3 a>=2, a>=-3 2 and -3 2 at this time -3 2<=a<0 is desirable.

a<0: -3 a>=(x 2+x) and the right range is [-1 4,2).

That is, there is -3 a<=-1 4, a<=12, and the range of values of 0 in this case is -3 2<=a<=12

This is a difficult question, and if you don't understand it, you can ask it.

Hope it helps you a little!

f(x)=(a-3)x-ax³

f(1)=-3

Therefore, only f(x) needs to be monotonically decreasing.

f'(x)=-3ax +a-3 0 is established first f on (-1,1).'(1) 0 and f'(-1) 0, solution a -3 2a=0, this is clearly true.

When a<0, the function g(x)=-3ax + a-3 axis of symmetry is 1 6, and only g(x)max=g(1 6) 0 is required

When a>0, the function g(x)max=g(-1) 0 solves a

Domestic essay questions are really boring!! Teacher, I want to say to you: I want you to see what makes a real teacher!!

First of all, list ** name the recent test results (the average score of the bottom 10) and the relevant recent experience. If you have a problem, you can turn to experienced teachers, who have always been very enthusiastic about young people. With "road signs" on the road, we can avoid many detours

I guess it would be nice to compare the student's grades at the time of admission with the current grade, and use excel to make a chart to calculate the score growth rate.

It's hard to recruit or recruit if you take the exam,,, age is not a problem... If you take the vocal test, the key depends on how your voice is originally conditioned, and how well you sing

Sing bel canto words·· There should be no requirements for the figure

A few years·· I don't know, but it's really not easy to test
