Line graph

Average annual expenditures on cell phone and residential phone services, 2001-2010.
---------------------------------------------------------
The line graph compares the yearly spending on mobile and landline phone services in the US between 2001 and 2010.
It is clear that expenditure on landline phone services fall steadily while mobile phone expenditure increases sharply. In The year of 2006 marks the point in which the spending on cell phone services overtook the expenditure on landline services.
In 2001, US consumers spent an average of $700 on residential phone services, compared to nearly $200 expenditure on mobile phones.
In 2006, the amount of budget spending on both in mobile phones and in residential phones was $500. The following 4 years, the expenditure on cell phones surpassed landline expenditure with a larger gap at the end of the period of time given.
By 2010, Americans had paid on average over $700 on cell phones, while the expenditure had spent on for landline phones was just over $400.

Good job, Xu Xu! The best advice I can give is to make sure you know when to use plural nouns rather than singular nouns. Also, make sure you have the correct names and dates in your data summary--the graph goes to 2010, not 2020, and I think you meant to say "US" where you put "UK" since you later continue talking about America. 

The things I want to say, but I can't say

Due to the my shy personality, I can't usually say what I think directly (and also often indirectly) generally. My thoughts are invisible to people, so I can see that the possibility of misunderstanding me is really high. and also they do that. I don't know what is the reason of causes my shyness; maybe it comes from the fear of saying something wrong. But the main factor of this fear is about being misunderstood by people. When I don't say anything to anyone, they misunderstand me already. This is my paradox. I wished to erase what I wrote, but I must start from one point :)

Good job, Hasan! There were only a few spelling errors, and the rest of the pink shows where changes make the writing easier to understand. I'm shy too, so I totally understand this! Great job getting out of your comfort zone to write this :)

Reading material worth considering

I gave my students the reading material as below:
'It's quite common for single-handed.
Diplomats must give the only correct answer by himself.
At the same time keep in mind
The motherland has no prophet for backup."

These were sentences from the diplomat Lavrov's poem. We all have time to give the only correct answer by ourselves. If you have experienced such things, you must be impressed. Maybe you haven't experienced these, and you will have your own consideration.

Write an essay based on the reading material to describe your feelings.

I am supposed to upload one of my student's essays later this week.

Good job! What did you mean by "impressed" and "consideration"? If these words are supposed to describe the effect that the poem has on people, there are more accurate words to use. (Impressed is like when you feel admiration for the writer; consideration is when someone considers or thinks about something. I can't think of any better words to use at the moment...sorry :/ )

To fill in the blank, you would say, "Our office will be closed on Christmas." Both sentences are technically correct, but they mean slightly different things. "On Christmas" refers to the actual day of Christmas (24 or 25 December). "At Christmas" would be more general, kind of shorthand for "at Christmastime," so any time in late December.

Graduation Ceremony

This Sunday is my graduation ceremony. Recently, it has rained all the time. I hope it will be sunny on Sunday so that I can take photos with my friends and teachers. Besides, I hope my friends would have a good time on Sunday.

Great job! If your graduation ceremony really is on Sunday, I hope it's sunny and that you and your friends have a good time!

My problems with learning English

Though in China nowadays, every young person takes English lessons for about 7 years at least, not everyone can speak out fluent English, or write down a beautiful article.
As for me, the slang and phrase verbs are definitely too hard.
It's easy to make me understood by Americans (Thanks for your mercy, my kind friends), but I can hardly catch the spoken expressions in TV dramas or daily talking.
And the vocabulary which shows one's good educational background is my direction. Since my words are so limited, that when I am typing here, I can only use the simplest words.
Besides, foreigners cannot understand what I say because of the Chinese way of thinking. That really makes me upset.
Anyone willing to help me?^-^

Hello! The one question I have about the post itself is what you meant by "direction." "Direction" is like where someone is going. A "goal" would be where you want to be. I think your goal would be having a larger vocabulary.

For that, watching English TV with subtitles, listening to music in English, and reading simple books in English would be a great way to both expand your vocabulary and learn to understand American (or British, or Australian) slang. Talking to people fluent in English on places like italki is a good idea too, to better understand how to express yourself and how you think and how other people are expressing themselves too :)

The challenge

It's all a challenge. Every day, every moment, no matter where you are, no matter what you're doing, someone is judging you and most of the times you might be doing the same. I might see someone who looks bad, dresses himself badly, and/or doesn't take much care of his features. You're judging what you can see, and even if you think you aren't judging that person even if you think or at least try to convince yourself that looks don't matter, your subconscious will automatically judge that person. But this is not just about looks, it's about the judging process. The same thing could've happened the other way around, you speak to someone and you realized his instruction is not really top level, if anything it's lower than average and you immediately assign -1 points, if he/she's good looking and you're not, that -1 turns into -10. Yet that's not all. EVERYTHING can be judged. The way you walk, how good you are at a certain subject, how good you are at a certain sport ...ANYTHING. Look around you, there's someone who's better than you at something and you're better than him at something else, but that doesn't mean he's better than you or the opposite. Each of us has a path we choose, we decide what we want to achieve and in which fields. The point is that this judging will always be there no matter how conscious the choice not to judge is, so you could either accept it or try to get better in those areas you feel you're lacking. Let me know what you think in the comments below.

From a language standpoint, you're looking good and this was understandable. The one thing you have to watch out for is your comma and period placement--the commas and periods go immediately after the word before them, and the space comes after, as shown. It is very difficult to read with misplaced commas and periods. Other than that, good job, Alessandro.

First part-time job

My first part-time job was as an archivist at an Eye Care Clinic. It was a good job for a sixteen-year-old high-school student. I had to be at work at 07:00 a.m and would leave by noon. I remember that I got really excited about the job. I would always give my best while working because it was not easy to find a part-time job back then, and the money that I was getting was enough to buy my stuff and to party - that was all I wanted.
In the first weeks when I started the job, the archive was confusing. There were mountains of files spread all over the place - very disheartening. Whereupon, It occurred to me that as soon as I managed to make things neat, my job would become much easier. I toiled over those files for two months to get them organized. Even my boss was surprised when she looked at it. After that things loosened up.
I worked as a part-time archivist for a year. Then, after I graduated from high school, I began working full-time. What I liked about my occupation was, on the one hand, the workplace atmosphere. There were the doctors, the nurses, the secretaries, the people of the management sector, the cleaners, and the archivist, of course. Everyone got along well. Every month there was a worker-birthday list pinned on the kitchen's wall. So, The doctors, to celebrate the employees' birthdays, would pay for a special breakfast for everybody.
On the other hand, I think working in an archive for a long period of time can be detrimental to a person's mental health. You are confined within a cramped room, alone, doing monotonous tasks all day long. After a while it starts to get boring. It was a nice part-time job, but it's not a job that I would like to go back to.

Great job, Lucas!
