While I will explain a bit about the science of stress and relaxation a little later simple way to think about it is that our body 's stress response works like a car alarm. Keep us safe by warning us of the presence of danger in our immediate environment.

But instead of warning us with a loud and annoying sound,our body alarm system lets us know that something is wrong by creating changes in our neurochemistry (神经化学).If you've ever expe­rienced pain in your stomach,periods of extreme anger, inability to focus or even insomnia (失眠),chances are your body was paying the price in those moments for the brain chemistry of stress.

So if it's so uncomfortable,why not just get rid of stress altogether?

This is not only impractical,it would be dangerous. Let's go back to the metaphor (比喻说法)of the car alarm. If the alarm is turned off altogether,the car is exposed to continual danger without there being any way of your knowing about it until it is too late. It would be like walking through the jungle without any fear signal in the presence of a poisonous snake or other dangerous animals — while it might feel “nice” to be so relaxed,your body actually needs the stress response not only to remind you of danger but also to offer extra adrenaline (肾上腺素) for your heart and extra blood and oxygen for your arms and legs.

However,if the car alarm goes off at any time,someone just looks at the car with a bit of an attitude,and it becomes equally useless. Not only do we stop paying attention to it,but it begins to drive us and everyone around us becomes a little bit crazy. In the case of our bodies,walking around in a constant state of alarm also has some pretty alarming health consequences,which we will explore in greater depth in the next chapter.

What are American high schools like? Well, I’m happy to tell you what I know.

When I started school here, it had already been a week since the school opened. At this school, freshmen usually go on a trip for about three days at the beginning of school. Unfortunately I missed that wonderful trip, which would have been the best time to get to know my classmates. I was really sad. I wished I’d known about it earlier.

Despite the disappointment, however, I gradually adapted to my new life and school.

There is a space in the basement of the teaching building where students chat and meet each other. As we do not always have the same classrooms and classmates, the school wants us to get to know each other there. Students usually come to school early, sit in that space and have fun. Around the space, there are many lockers for students to leave their books in, so that students do not have to carry a heavy schoolbag everywhere.

It really surprises me that we have almost no textbooks. We only have textbooks for World History and Algebra 2 and they are big and heavy, like bricks. For other classes, we only need binders (活页夹) with paper in them. Without textbooks, students learn things freely and actively. For example, my humanities teacher just teaches us what is in her mind at the time. We never know what we will learn.

Another difference between American schools and Chinese schools is that American schools care about students’ morality more than their academic studies. For example, if you do not finish your homework, you will just be asked to do it later, but if you cheat or lie, you will get a warning or even be kicked out.

I think that most students here are good at schoolwork as well, but compared to Chinese students, they can make learning a more joyful experience. I think we should take the good points from our two different kinds of education to perfect our approach to studying.

Mum,it’s me.Hopefully,this Mothering Sunday you will get to hear those three words.I will,of course,try to phone you.I hope we will be able to speak for the allowed 10 minutes.But I suspect many inmates will be using the phone,so if I don’t call and if we don’t speak,then this is what I would have said:
It’s not your fault that I am here.I know that deep in your heart you have questioned whether my current circumstance is somehow your fault,if the reckless stupidity of my past is somehow a failure on your part.It is not.Only one person is to blame,only one person should hurt — me.You have always taught me that when the room goes dark,you can wait for the lights to be switched back on or you can search in the dark and turn the light on yourself.You are my light.You always have been and always will be.There is nobody I admire more,nobody I have strived harder to please in my life,which is why my current failure hurts me so much.
I am so sorry that I will not be there to see you,but I want you to know that now,as always,you are here with me.In my darkest hours,and in the coldest loneliness of my past few months,my mind has so often wandered to the past,to when it was you and me — and I have been able to smile.Yours is the strength that I draw upon.
A parent’s job is to make sure that they pass on the best of themselves to their children.You have done that.It is the inner you in me that will get me through this.
I have failed you so epically,but you have never failed me.If I think back to the tears I shed when Dad left,all those years ago,I see you through their misty glaze.You holding me and you telling me we’d be OK,and we will be.We are and always will be the best team.
Childhood heroes such as footballers,actors and rock stars are clichéD. If the job’s done right,a child’s heroes should be their parents — you are mine.The strength you showed after the divorce from Dad to find your biological parents,to go to university and get your teaching qualifications,to begin your life again,is the strength that I draw on now.It is the belief in myself,it is the belief you have in me,that tells me that once I am released I can and will rebuild my life.I will make you proud again.I will make you happy to have me as your son.Yours is the will that gets me through every day.
I don’t believe you can judge a person for the mistakes they make,as we all make them,but you can judge them for what they do afterwards.And after this,when it is all over,you will still have a son with the same hopes and dreams.They have not diminished. If you can dream it,then you have to believe it can happen — right?
So this Mothering Sunday,please think back to that morning in the 80s,the first Mother’s Day without Dad,when a six-year-old me got up early and made breakfast for you.Do you remember it?Could you ever forget?A slice of bread a doorstep thick and a wedge of cheese equally dense.You didn’t have to eat it,but you did,chewing every dry mouthful.I know now why you forced yourself — because it had been made with love.Well,things don’t change this year — this letter is that bread and cheese (it sure has plenty of the cheese!).
I love you so much.I am sorry I have let you down,but you have taught me that we will always pick ourselves up and become better than we were before.Thank you for everything and this year,more than ever:
Happy Mothering Sunday.
Love,your son
