The teacher assigned an essay on Homework Do Homework , and I had no clue at all, and I was in my s

Pros and cons of copying homework.

There are both advantages and disadvantages to copying homework.

From the disadvantages, there are many reasons why copying homework is not good.

1. Plagiarism will affect one's performance, so that one's consciousness will change from active to passive, resulting in a dependence on plagiarized homework. Of course, this is only a one-sided statement, and there are two sides to everything.

2. Students will be more lazy as a result;

3. Students' grades will be worse;

4. Class discipline will be worse.

All in all, copying homework does more harm than good.

Copying homework is sometimes not a bad thing, it depends on the level of the copyist, some people copy homework first to carefully look at it and understand before copying, this is also some people's learning methods, in the process of copying to find doubts and solve, but to improve their ability, but these people are highly dependent on others; Some people just copy and don't look at anything, which is not good for him at all, and we don't recommend this practice. Copying homework has led to the disappointment of parents' hopes, and the blood and sweat of parents have not been fruitful, and I have found that at this moment, copying homework is carrying too many sins that do not need to be carried. If you don't copy your homework, maybe how many parents have their dreams come true.

Homework is a kind of thing with Chinese characteristics that the teacher reads according to the knowledge read in class and then asks you to write it by hand in order to waste pen oil.

Pls are you in elementary school, junior high school or high school.

If you want to fly, you will fly.

When I was a child, I had a dream in which I was flying in the sky, but when I woke up, my hopes were shattered.

Grandma said, "Child, you can't fly if you want to. Qi Li: "No, I will definitely fly, definitely!" Grandma smiled and walked away.

So, I made a pair of shapeless wings with my immature hands. Holding the wings, I tried to fly excitedly, but the feathers were scattered on the ground, and I couldn't fly. I cried.

Time passed, in the blink of an eye, and I graduated from elementary school. Watching my classmates fly to the middle school where I imagined, and I just stood there in a daze, looking at the report card, what a kind of longing for wear! However, this time, I didn't cry, I just secretly gritted my teeth and told myself that one day I would fly!

Because I know that if I want to fly, I can fly.

With faith, I stepped into the threshold of junior high school. Junior high school is a crucial stage, and I know that I must not lose in this important way.

In class, I stared at the blackboard, merging every word of the teacher's speech with my own flesh and blood; After class, I read the textbook and searched the knowledge in the depths of my heart and buried it; In the evening self-study, I decorated each homework book with delicate characters and handed it to the teacher.

So, in the first unit test, I won the championship, I stepped out of the dark corner, and I knew that I was going to spread my wings and take off.

Day after day, year after year, I did not slack off, because in the depths of my heart, a seed of faith was sprouting.

For 3 years, I have paid without shame.

And now is the time to face the first choice in life, and the high school entrance examination is just around the corner.

I struggled! The black pencil is scratched all over the white scratch paper, the pen is constantly turning, and there is a "rustle" sound, and no one wants to fail at this critical moment. What comes to mind is trigonometric functions and mechanics, and one by one the paper balls are thrown into the paper basket, helplessly, picked them up again, and continue to ponder.

I spent every day in the exam, but looking at my results, I smiled, it was a heartfelt and comforting feeling. Hearty laugh. Because at this moment, I am already flying invisibly, and there is a clear blue sky in front of me.

Trailing blood trails of struggle were left behind me, and that was a testament to my efforts, and I flew, because I always knew that I could fly if I wanted to!

The question is unclear and cannot be answered.

Write it yourself, you won't, stupid.

Assuming that the alloy contains x grams of gold, then it contains 770-x grams of silver.

First, 1/19th of the mass of x grams of gold is equal to 19 of x 19, and secondly, 1/10 of the mass of 770-x is equal to (770-x) 10 of 770-x grams of silver in water

Finally, the weight of the entire alloy is reduced in water = the weight of x grams of gold is reduced + the weight of 770 - x grams of silver is reduced in water.

That is: 50 = x 19 + (770-x) 10

Calculate that x=570 and 770-x=200
