Below is a selection from a popular science book.

If blood is red, why are veins(静脉) blue?

Actually, veins are not blue at all. They are more of a clear, yellowish colour. Although blood looks red when it's outside the body, when it's sitting in a vein near the surface of the skin, it's more of a dark reddish purple colour. At the right depth, these blood-filled veins reflect less red light than the surrounding skin, making them look blue by comparison.

Which works harder, your heart or your brain?

This question depends on whether you're busy thinking or busy exercising. Your heart works up to three times harder during exercise, and shifts enough blood over a lifetime to fill a supertanker. But, in the long run, your brain probably tips it, because even when you're sitting still your brain is using twice as much energy as your heart, and it takes four to five times as much blood to feed it.

Do old people shrink as they age?

Yes and no. Many people do get shorter as they age. But, when they do, it isn't because they're shrinking all over. They simply lose height as their spine(脊柱) becomes shorter and more curved due to disuse and the effects of gravity(重力). Many (but not all) men and women do lose height as they get older. Men lose an average of 3－4 cm in height as they age, while women may lose 5 cm or more. If you live to be 200 years old, would you keep shrinking till you were, like 60 cm tall, like a little boy again？No, because old people don't really shrink！It is not that they are growing backwards—their legs, arms and backbones getting shorter. When they do get shorter, it's because the spine has shortened a little. Or, more often, become more bent and curved.

Why does spinning make you dizzy(眩晕的)?

Because your brain gets confused between what you're seeing and what you're feeling. The brain senses that you're spinning using special gravity and motion sensing organs in your inner ear, which work together with your eyes to keep your vision and balance stable. But when you suddenly stop spinning , the system goes out of control, and your brain thinks you're moving while you're not!

Where do feelings and emotions come from?

Mostly from an ancient part of the brain called the limbic system. All mammals have this brain area—from mice to dogs, cats, and humans. So all mammals feel basic emotions like fear, pain and pleasure. But since human feelings also involve other newer bits of the brain, we feel more complex emotions than any other animal on the planet.

Why do teeth fall out, and why don’t they grow back in grown-ups?

Baby (or “milk”) teeth do not last long; they fall out to make bigger room for bigger, stronger adult teeth later on. Adult teeth fall our when they become damaged, decayed and infected by bacteria. Once this second set of teeth has grown in, you’re done. When they’re gone, they are gone. This is because nature figures you’re set for life, and what controls regrowth of your teeth switches off.

If exercise wears you out, how can it be good for you?

Because our bodies adapt to everything we do to them. And as far as your body is concerned, it’s “use it, or lose it”! It’s not that exercise makes you healthy, it’s more that a lack of exercise leaves your body weak and easily affected by disease

高三英语阅读理解简单题查看答案及解析

Most of us long for relationships in which we are loved and accepted. Our hearts’ desire is to give and receive love in relationships that make us feel that even if others disagree with what we do or say, they still love us, accept us, and appreciate what we give to the world. While it would be wonderful to have these types of relationships with all people, we know that’s hard to do. However, we can have such relationships with some others, but only when we first have them with ourselves—and, strangely, this is often the hardest relationship of all.

Do you love yourself? You may think you do, but do you really? There’s only one way to find out— by taking a close look at what you think, say, and do. You may not like some of what you find, but if you are serious about really loving yourself, you can use this insight to do some positive inner work. Here’re three ways for gaining greater personal insight for deeper love:

Listen Closely to Your Thoughts

Your thoughts will determine your actions. One thing helping you to listen to your thoughts is keeping a journal. It is not necessary for you to write in it every day, but it helps to record various insights you gain as you go about your life. Instead of using a big notebook, you might use a small notepad that you can keep in your pocket for easy access to record your thoughts as they occur to you. Whichever method you choose, what’s most important is that you write your thoughts down. It will help you know what’s in your heart.

Be Honest with Yourself

To do this, you should pay attention to your actions. Actions speak louder than words, and they always tell the truth. If you say you love your job, but your actions say otherwise, which do you think is more reliable? On the other hand, if you say you’re not good at a certain job, but your actions say otherwise, that’s also important. What do you do with this insight? You can use it to make more positive choices in your life. By being honest with yourself, you will act according to truth instead of just what you tell yourself.

Take Quiet Time to Listen to Your Inner Voice

This is similar to the first point, but it takes a step further— beyond the natural mind to the heart that cannot be seen. You may want to use your quiet time to think deeply. However you use this time, the key is to shut out all of the noise around you by focusing deep within yourself. Breathing deeply during quiet time will also help you focus. I know it’s hard to find quiet time during a particularly busy day, but it’s so important— even if it’s just 10 minutes a day and you have to hide somewhere to get it. Quiet time can really make a difference in your life.

Despite what your mind may be telling you, you can have love with no limits. The key is to unconditionally love yourself first.

1.. By looking deep into what we think, say, and do, we can ________.

A. know whether we really love ourselves

B. appreciate what we give to the world

C. realize what type of relationship we long for

D. know whether we are loved and accepted by others

2..An important way for gaining personal insight is to ________.

A. do some positive inner work

B. keep a journal wherever you go

C. look closely at what others say about us

D. pay attention to our thoughts

3..The insight we gain from our actions can help us ________.

A. focus our attention on our jobs

B. make more positive choices in our life

C. act according to the truth

D. tell the differences between our words and our actions

4..It can be learned from the passage that if we want to have love without limits, we must first of all  ________.

A. be honest with ourselves anytime

B. give our love to others generously

C. love ourselves unconditionally

D. take quiet time and think deeply
