No. Your first example implies that you aren't at home but will be soon. If you just said "I am not at home," then you aren't implying anything about whether you will be there soon or not. It's just a statement. The same thing applies to your second sentence. "I haven't been at home yet." implies that you plan to be there, whereas "I haven't been at home" just states that you haven't been there recently.

Only by volunteers. Volunteering is when you choose to work without pay. So whatever is being done here is being done by people who are choosing to work without being paid.

Second notebook entry : Introducing myself

Hi everyone,

I'm here to introduce myself. My name is Marie, I'm 22 years old and I live in France. I study chemistry in at University and I really like that. But in France, at university, English is not a priority. As we all know, it is hard to learn a language by ourself ourselves! (the English don't put the space before !'s and ?'s)

Also Otherwise, I had practiced the basketball for a long time ( 8 years ) but I had knews new issues which make made me stop. I started again to practice again this year and honnestly it is hard to feel again all the sensation again after a 4 years hiatus. Besides that I like listenning music, and walking around Paris with friend. (with a friend or with friends, depending on your intention) 

Really hope we can exchange together on our language but and also our culture :)

Lets loose means to start in here. So the phrase "until the rain lets loose" means "until it starts to rain." Daggled means to run or drag though a puddle. So daggled females would be females who had to walk through some puddles to get wherever they were going.

To express the idea of wanting something you add 고 싶어 (go sipeo). In this case, the verb used is to see. The Koreans say "I want to see you" to express the same idea as "I miss you."

Did wouldn't be the same in either of those situations. Would has several uses, primarily creating the conditional mood. The conditional mood creates hypothetical situations, things that don't exist. "I would help you" implies that I can't help you for some reason. I would have gone (but I was unable to). And in the first situation, "Why would anyone kill themselves," no one has killed themselves, but you are creating a situation in which someone has, if that makes any sense. In the second question, did would be grammatically correct in the situation, but it does express the same meaning. "Why would you ..." is asking what caused her to think he was lying. It's technically present tense, whereas did is past tense. Why did you (in the past) think I was lying vs why do you think I am lying right now. I'm having a little trouble trying to explain the difference between the two in this situation, so if what I've said doesn't make sense, hopefully someone else can explain it better. Now onto the rest of would. Would can be used to make a request more polite. "I would like a glass of water" is more polite than "I want a glass of water." Or using an imperative: "Would you take out the trash" vs "Take out the trash." Would is also used as the past tense of will. Will is used to create the future tense as in "I will go to the store." "I would go to the store," can refer to something that has happened in the past, but is being told from a point further in the past. For instance, if you were telling someone about how you met your wife, you might say "She didn't know it then, but I would marry her a year later." I hope this helps. Let me know if you have any more questions.

Kids say the darndest things.
