I think commas belong in all of those sentences. There is another way to structure sentences to show that same idea, which is probably used more often than "When speaking with adults, be polite." Here are a couple examples:

Be polite when speaking to adults. 

Be attentive when listening to a teacher's explanations. 

Overall, your English is very good and these are nice sentences! Good work! :) 

Lying is necessary, liars are a problem

We are taught that lying is something bad, although everybody lies at least sometimes in their everyday life. Normally, we feel guilty when we do it. If we stop to think about it, we can notice that lying is not wrong. Lying is not bad itself. Lying is one important aspect of human beings. We can choose between telling the truth and lying. To live in harmony, sometimes we have to tell some white lies because we don’t want to hurt someone or we prefer not to get in trouble.

Lying is not a problem itself but liars are. People who like to lie every time and don’t care about that consequences of their actions are a big problem. Everybody hates liars. They are unethical people. Frequently they take advantage of innocent people. Scientist are searching for a good method to recognize liars. Though there are some characteristics that you can use to guide yourself, it is not always easy to discover a lie. We only have our intuition and we have to decide if we can trust or not.

Really great entry!! I could definitely understand all of your ideas. Your English is really good! 

My Work Life

I have to wake up and go to my office at half past seven o'clock from Monday to Friday. Before I go to my office, I have breakfast. I would have various food for breakfast like rice, noodles, cookies, and so on. I prefer having a cookie for breakfast as it is my favorite food. After my breakfast, I have to go to my office by train. Sometimes I would go by bus if I don't catch the train in time. At my job, I am working in help desk department. I have to answer questions from clients. It is difficult work for me because I have to find solutions and explain the reasons to the client. Usually, I just need to work for eight hours from Monday to Friday, but there would be exceptions like colleagues have a sick leave then I would be supposed to increase my working hours. After I come home, I would take a bath and eat dinner. I would read some articles on internet before I go to bed. That is my work life. 

Excellent English! I only noticed little mistakes, and overall I was a bit confused by what tense you're writing in. Great entry!

As the elections in the U.S.A are coming, our English teacher has told us to express our opinions about who will win. I suppose that the new American president will be Hillary Clinton and there are a lot of reasons in order to back my position.
First of all, one of the most important arguments in favour of my position is that Mrs. Clinton has thousands of ardent supporters who will definitely vote for her on November 8th. There is a huge social movement to elect the first Madame President in the United Sates, so this makes her even more popular among Americans. As some years ago they chose the first African-American president, there is no doubt that the First Madame President will make the U.S.A. a more democratic country in the eyes of the world.
Secondly, Hillary, the first female presidential nominee of a major party, is widely supported by the media. She's invited to lots of different shows and debates. Moreover, lots of singers, actors, and other famous people are making her the new personification of American politics.
Thirdly, Hilary Clinton is a good spin doctor, which means that she can easily justify all the blames addressed to her by turning the public attention to her opponent. Just remember the large e-mail conflict that took place a couple of months ago - Mrs. Clinton managed to make it less controversial and dangerous for her reputation.
Last but not least, the main cornerstone of her popularity is promises, promises and promises. She promises to fulfill all the desires that the Americans have. She feels strongly that under her administration, the U.S.A will become a more powerful, economically developed and socially oriented country.
Nevertheless, that's just my personal opinion. Nobody knows who will really win.

If you could push a button to kill someone you didn't know in order to live more 15 years, would you do it?

My Day

Hi. My name is Jood. I am usually busy and in a hurry. I get up at 4 o'clock. I pray and read from the book of God. Then I start on self-learning. In the afternoon, I go the kitchen and cook lunch for my family. I usually don't leave my house. I go to sleep early, at 9 or 9:30 p.m.
