The human body is a machine that can raise lots of interesting questions．Why，for example，are yawns（呵欠）contagious（传染的）？What's up with ice﹣cream headaches？ Here are answers to these and other questions about our bodies．
Why do I get a headache when I eat ice cream too quickly？
Scientists aren' t exactly sure what causes the brain freeze when we eat ice cream or other super﹣cold foods too quickly，though some believe it's the result of changed blood flow in the nervous stem．Blood vessels in the head tighten to stop the loss of body heat and then relax to let blood flow rise；that sudden rush of blood is what causes the headache．You can improve an ice﹣cream headache by rapidly rubbing your tongue across the roof of your mouth to help warm up things．
What causes my stomach to make a low continuous noise when I'm hungry？
Actually，your stomach makes noise whether you're hungry or full；you just hear it more clearly when you're hungry．Think of your digestive tract（消化道）as a really long tube lined with smooth muscle tissue． These muscles move food，fluids and gas through your digestive tract． A ．It can make you feel embarrassed（尴尬的） but is nothing to worry about．
Why do I blush when I'm embarrassed？
When you're embarrassed，your brain releases a shot of adrenaline（肾上腺素），which makes your heart race and blood vessels become larger in size．All this happens to increase blood flow and oxygen delivery throughout the body in a fight﹣on﹣ flight reaction（对抗反应）．There are a lot of tiny blood vessels in your face，which turn noticeably redder from this sudden rush of blood．As for the actual function of blushing，researchers are still trying to find that one out．
Why are yawns contagious？
Have you ever yawned in front of someone，only to have them yawn right back？ It's a common thing but researchers don't have a good explanation for it．They do，however，know this happens only with humans and chimpanzees（ 黑猩猩）．A bigger question puzzling scientists is why we yawn at all It used to be thought that yawning showed that oxygen to the brain was not enough，but that's just a myth．A growing body of research now shows that yawning is nature's way of keeping our brains cool．

Dear Sir,
I am writing to you about my stay at your hotel. My wife and I arrived on Saturday, May 15th and stayed for a week. Though we were treated well and found the service excellent, we think there are one or two things we should bring your attention.
1. We hoped for a nice holiday from our busy work lives, and your ad said “comfortable and quiet”. We want to have a chance to enjoy ourselves. However, we were always waken up by the noise every morning. Is it really necessary for the workers to start their repair work so early?
2. We hoped to swim in your “wonderful pool”. To our disappointment(失望), we found that it was closed for the whole time of our stay.
I hope you do not mind my writing to you about these things, but I would be happy if you could give me some explanation(说明). As I said at the start, it is a pity, and your service is so good in other places.
I hope to hear from you soon.
Yours sincerely

Here are the kinds of things people say when they invite someone to their homes: “Would you like to come over for dinner this Saturday night?” “Hey, we’re having a party on Friday. Can you come?”
To answer an invitation, either say thank you and accept or say you are sorry and give an excuse. “Thanks, I’d love to. What time would you like me to come?” or “ Oh, sorry. I’ve tickets for a movie.”

For example, “Please come over for a drink sometime.” “Why not get together for a party sometime?” or “Why don’t you come over and see us sometime soon?” They are really polite ways of ending a conversation. They are not real invitations because they don’t mention(提到、涉及) a certain time or date. They just show that the person is trying to be friendly. To answer expressions like this, people just say, “Sure, that would be great!” or “OK! Thanks.”

Today I want to introduce a writer Greg Mortenson to you, especially one of his works called Three Cups of Tea. It has been one of the best sellers. Why can it be so popular?
Greg Mortenson was born in the state of Minnesota and grew up near Mount Kilimanjaro in Tanzania. Mortenson later became a nurse.

Mortenson reached a poor village called Korphe in the Karakoram mountains of Pakistan. The villagers had never seen a foreigner before. They provided food and a place for him. Mortenson became friends with the villagers and he wanted to see their school. But they had no school.

Do you feel lonely when your best friend isn’t around? Of course, yes. Here’s our advice to you—and to all kids who feel lonely sometimes.
You may feel lonely at break or lunchtime when a best friend isn’t around—maybe because he or she moved to a different school or a different class. You want to have new friends, but how do you make them? Maybe it seems everybody else already has his or her friends. But remember, there’s always room for more friends.
Start by looking around your classroom—think about which kids you’d like to play with at break. Look for chances to say hi to them, smile, and be friendly. Offer to share something or express your appreciation (欣赏) to them. Invite someone to play with you or say, “Do you want to sit here?” in the lunchroom. When you’re at break, walk over to kids you want to play with, act friendly, and say “Hi, can I play, too?” or just join in.
If you have trouble doing this or if you’re feeling shy, ask your teacher to help you make new friends. Teachers are usually pretty good at matching up friends. The best way to make friends is to be a friend. Be kind, be friendly, share, say nice things, offer to help ---and pretty soon, you’ll have one, or two, or even more new friends.
You might still miss that special best friend. But when you see each other, you can share something you didn’t have before he or she left. You can introduce him or her to your new friends! How do you feel when your best friend isn’t around you according to the passage?

Growing mushrooms（蘑菇）is probably the easiest thing you can do even if you are new to mushroom growing. It is becoming more common because restaurants are starting to create more dishes that include mushrooms.
Mushroom growing is easy. To start, you need to have a space where you are going to grow these mushrooms. It does not have to be a huge space but just enough for you to grow as many mushrooms as you need. When you have found the space perfect for you, you can start researching what kind of mushrooms you want to grow. There are a lot of mushrooms to choose from and not all of them are suitable to eat.
When you decide what kind of mushrooms you want to grow, you can start getting ready to plant the mushrooms. Sometimes you may want to hire some workers to help if you have a large mushroom farm, or if you are trying to start a professional mushroom growing business. Trying to have a business by yourself can be stressful. If you don’t have enough time to spend taking care of everything yourself, some helpers may be the best choice.
After you have started the mushroom growing, you should regularly check that your mushrooms grow properly and that they are not being attacked by any pesticides（农药）or any other animals or something that could be dangerous to them. That is the worst part of mushroom developing. Protect your mushroom farm well with a fence（围栏）or a gate so that only you and your workers can get in and out.
