"Numbers of Relevance" I think in this case means numbers that are relevant to something or someone. In other words, they are important or somehow have some importance to a particular subject or matter. So, in the short scene that you describe the numbers on the list are relevant in that they are the codes to open particular lockers in the locker room.

A muon is a type of particle like an electron, or a part of an atom. Basically, it's a physics term. The joke is similar to one that I know where it's an interrupting cow instead of a physicist. I'm not sure if you are familiar with knock knock jokes but the basic structure of the joke is: person A: knock knock person B: who's there? person A: <someone or something> person B: <someone or something> who? person A: <someone or something><joke>. The joke is usually a pun or play on words. In the interrupting physicist/cow joke, person A says "Muon!" or "Moo!" before person B gets to "who". The physicist or the cow interrupts person B. So that's the joke. Hope that makes sense.

I want to be an Interpreter

I want to be an Interpreter.It is an interesting and useful profession!
Once at the class of Literature in Literature class, our teacher told us that, when translated, literary works lose much of their beauty. She said that poetry is very hard to translate. From Since that day I have had a dream*. I want to have my favourite books in the origional and to know the languages they are were written in, so I can enjoy the real beauty of these books.
I also like reading books about other countries and cultures. It is so interesting to learn that other people think differently.
I want to become an interpreter because of some these reasons. It is an interesting profession because an interpreter meets people from different countries all the time and has an opportunity to learn much about them. Besides,this profession is very useful because it helps people to understand each other.

*or "From that day <em>on</em>, I had a dream.

italki is a good website

I knew learned of*  italki from my classmate 4 days ago. Then I registered and became a member of italki. I think italki is a great website. I haven't hadn't thought that I could communicate with so many foreigners before. Yesterday was the first time i talked with a foreigner in English. I was so nervous! But my england English friend said that my listening was pretty good and my English was not bad^-^. I'm very greatful to him, he is so kind to help me and his accent is normative. yesterday Last night I talked with two Pakistani girls. They are so lovely!
All in all, I appreciate italki for offering me a site to improve my English and make more friends. But i must state that I'm not italki's spokesman and this essay is not an advertisement!hahaha

Hong Kong Government sends money 香港政府派錢:16 Jun 2011

香港政府派錢

Hong Kong Government sends money

香港政府今日終於定出派發6000元給市民的日期和具體方法。我身為一個香港市民，當然可以受惠。

The Hong Kong government, today, eventually have has decided the data and specific way to distribute 6000 Hong Kong dollars to the public. I, as a Hong Kong resident, of course can benefit from it.

其實我發到政府派發的款項已不是第一次，因為我除了是香港市民外，我還有澳門公民的資格。而澳門政府早於四年前已開始於每年以一次性的方式撥項給普羅大眾，作為舒解民困的其中一個方法。這亦是政府為了解決民怨的一種技倆。而這種方法是否有舒解民困的成效，則不得而知了。但從經濟學的角度看，派發一次性撥款這一措拖在短期內會刺激起通脹。

As a matter of fact, it wasn’t isn't the first time I have received the money from a governments because I not only am the a Hong Kong resident, but I also have citizenship of in Macau*. The Macau government has started distributing one-time funding to residents as early as four years ago as a way of relieving the hardship, and also as a governmental tactic to address grievances. The effectiveness by using this way of this tactic to relieve the hardship is unknown. But from an economic point of view, the distribution of one-time funding will stimulate the inflation in short term.

*You can also say "I am also a citizen of Macau."

"Bite out of their (my/your/his/her) pocketbook" means it costs them money. "No immediate bite" means that it doesn't "bite" you right away. To understand the sentence completely, we need to know it in context. Whose pocketbook are we talking about? Is this sentence about credit cards?

My best guess is "reading comfort."

I am tired

I am very tired. Today I had a dance exam. I was very scared. I forget how long I was online on italki. Friday I have a fundamentals of mechanical manufacturing exam. Sunday I have an English exam. I am scared of it. I am very busying now.
