Are you a man or a mouse? When people ask this question they want to know if you think you are a brave person or a coward(胆小鬼). But you will never really know the answer to that question until you are tested in real life. Some people think they are brave, but when they come face to face with real danger, they act like cowards. Other people think of themselves as cowardly, but when they meet danger, they act like heroes.?

Lenny Sputnik had always thought of himself as a nervous person. He got worried before examinations. He worried about his job and his health. All he wanted in life was to be safe and healthy. Then, on 15th January 1982, a plane crashed into the Potomac River in Washington. Lenny went to the river to see what was happening. Then he saw a woman in the ice-cold water. Suddenly Lenny did not feel afraid. He kept very calm and did a very courageous thing. He jumped into the Potomac, swam to the woman, and kept her head above the water. Seventy-eight people died that day. Thanks to Lenny Sputnik, it was not seventy-nine.?

When you are in a very dangerous situation and feel afraid, the body automatically produces a chemical in the blood. This chemical is called adrenalin. With adrenalin in the blood system, you actually feel stronger and are ready to fight or run away. However, when you are completely terrified, the body can produce too much adrenalin. When this happens, the muscles become very hard and you find that you cannot move at all. You are then disabled with fear. That is why, when we are very frightened, we sometimes say that we are ‘petrified’. This word comes from the Greek word ‘peters’ which means ‘stone’. We are so frightened we have become like stone.?

Imagine your body is like the house you live in．Every day, your family creates rubbish．The rubbish builds up until it is put out for the weekly garbage collection．
Now, say you put three bags of garbage out, but because one of the collectors was away sick, only two bags are collected．You take the leftover bag inside to be put out again next week．The following week you put on another three bags, plus the leftover bag from last week．But again, only two bags are collected．Imagine this cycle is repeated over the following weeks．
This is a simple description of what happens to your body when your kidneys （肾脏）don't work efficiently．Your body is not thoroughly emptied of waste products．Other areas of the body such as blood pressure and red blood cell production are affected and the insidious process that may lead to kidney failure begins．
It's not uncommon for people to lose up to 90% of their kidney function before developing any symptoms．There may be no warning signs. This makes early detection （诊查）difficult．
Kidney's main job is to remove toxins（毒素） and unwanted water from our blood．Every day our kidneys clean an average of 200 litres of blood．Kidney failure may be a gradual and silent process, going unnoticed because there is no obvious pain．
Research shows that more than 35% of the patients requiring dialysis（透析）do not see a kidney specialist before they have to do so．Some risk factors for kidney disease such as age and genetic make-up are out of our control; however, some changes in lifestyle may help prevent kidney damage．Two major risk factors for kidney disease, diabetes （糖尿病）and high blood pressure, have been on the rise over the last few decades．Both conditions are chiefly affected by being overweight and not getting enough exercises, which are the potential (潜在的) risk factors for the kidney disease．
【小题1】The author gives the example of the house we live in to indicate that ______．

　　When you are in a very dangerous situation and feel afraid, the body automatically produces a chemical in the blood. This chemical is called adrenalin(副肾素). With adrenalin in the blood system, you actually feel stronger and are ready to fight or run away. However, when you are absolutely terrified, the body can produce too much adrenalin. When this happens, the muscles become very hard and you find that you cannot move at all. You are then paralysed with fear. That is why, when we are very frightened, we sometimes say that we are ‘petrified’. This word comes from the Greek word‘petros’which means‘stone’. We are so frightened we have become like stone.

I'm fat, I'm too skinny．I'd be happy if I were taller, shorter, had curly hair, straight hair, a smaller nose, bigger muscles, longer legs．
Do any of these statements sound familiar? Are you used to putting yourself down? If so, you' re not alone．As a teen, you're going through many changes in your body．And as your body changes, so does your image of yourself．Lots of people have trouble adjusting, and this can affect their self-esteem （自尊） ．
If you have a positive body image, you probably like and accept yourself the way you are．This healthy attitude allows you to explore other aspects of growing up, such as developing good friendships, growing more independent from your parents, and challenging yourself physically and mentally．Developing these parts of yourself can help boost （提升） yourself-esteem．
A positive attitude and a healthy lifestyle （such as exercising and eating right） are a great combination for building good self-esteem．
Some people think they need to change how they look or act to feel good about themselves． But actually all you need to do is change the way you see your body and how you think about yourself．
The first thing to do is recognize that your body is your own, no matter what shape, size or color it comes in．If you are very worried about your weight or size, check with your doctor to verify （核实） that things are OK．But it is no one's business but your own what your body is like—ultimately, you have to be happy with yourself．
Next, identify which aspects of your appearance you can realistically change and which you can't．Everyone has things about themselves that they can't change and need to accept—like their height, for example, or their shoe size．
When you hear negative comments coming from within yourself, tell yourself to stop．Try building your self-esteem by giving yourself three good things every day．By focusing on the good things you do and the positive aspects of your life, you can change how you feel about yourself．
The most important thing is to get help if you feel like your body image and self-esteem are affecting your life．
