Hey, hey, it’s your scientist pal Tania here. Today’s topic is…drumroll please…the human body!
Human bodies can seem weird sometimes. After all, your body didn’t come with instructions. No wonder a bunch of you sent me so many questions about it. Well, read on, curious human beings! I’ve got answers for you.
What are toes for?
Toes aren’t just weird little things that stick out of our feet. They do most of the work of keeping our balance. Toes act like teeny pegs. They dig in and make sure we stay upright when the going gets wonky.
But wait, there’s more! Ever tried to walk only on your heels? If so, you know that toes also put the spring in your step. Here’s how that works: When you raise your heel to start a step, your toes bend. That stretches your foot like a rubber band. As you finish the step, your stretched foot snaps back to normal. That springs your body forward to the next step.
When you run, your toes bend even farther. This creates a super spring that sends you soaring through the air!
Yup, toes let humans walk, run, and even fly. Well, for a few seconds, at least.
Why are babies so cute?
It’s not easy to care for a baby. Their diapers get stinky, and they cry a lot. And yet, they’re just so cute, right? Well, guess what? Their cuteness is the superpower that makes us take care of them!
Babies grab us with their powers of cuteness. We love to see a cute baby, hear it gurgle, or even smell its tiny baby head. And that’s great for babies. They need our attention.
But what do we get out of it? Well, we smile and get a warm and fuzzy feeling around babies. That feeling comes from chemicals that flood into our brains. Even when babies are smelly, loud, or sticky, those chemicals still flow. The chemicals make us happy, and that gets us to care for the baby’s needs. Both the needy baby and our happy-hungry brains win!
How come my belly makes that weird noise when I’m hungry?
It’s the middle of the school day, and your belly suddenly starts growling. It sounds like angry lions are fighting in there! But it’s just the strong muscles in your gut doing their jobs.
After you swallow some delicious food (mmm, like a juicy apple), your stomach soaks it in liquids called acids. These acids break food down into a gloppy goo. Your stomach’s muscles then pound and mix the goo for hours. They rumble around like a washing machine. Finally, your stomach calls it quits. It sends the goo into your small intestine. For several more hours, your small intestine groans. That’s because it’s squeezing all the good stuff out of that goo.
You can’t hear these noises when your stomach is full. But when your stomach is empty, it’s like a giant echo chamber. You get the very loud hint that your stomach has run out of food. And so does everyone around you!
Speaking of food, I keep thinking of apples now. I’m off to snack on one. I hope everybody enjoyed this! I’ll be back soon with more answers about the world around us.
Until next time, stay curious!

【推荐2】Mrs. Whitson taught us science. On the first day,she gave us a lecture about a creature called the cattywampus,an animal that was wiped out during the Ice Age. She passed around a skull(头骨)as she talked. We all took notes and later had a quiz.
When she returned my paper,I was shocked. There was a big red X through each of my answers. I had failed. There had to be some mistakes!(A)我确切地记下了老师说的。Then I realized that everyone in the class had failed. What had happened?
Very simple,Mrs. Whitson explained. She had made up all the stuff about the cattywampus. There had never been any such animals. The information in our notes was,therefore,incorrect.
Needless to say,we were(B)outraged. What kind of test was this?And what kind of teacher?We should have figured it out,Mrs. Whitson said. After all,at every moment she was passing around the cattywampus skull(in truth,a cat's).Hadn't she been telling us that there was no such an animal?She had described its amazing night vision,the color of its fur and any number of other facts she couldn't have known. She had given the animal a ridiculous(荒谬的)name,and we still believed her words were right.
(C)The zeroes on our papers would be recorded in her grade book,she said. And they were.
Mrs. Whitson said she hoped we would learn something from this experience. She told us not to let our minds go to sleep,and to speak up if we ever thought she or the textbook was wrong.

I was a freshman in college when I met the Whites. They were completely different from my own family. Jane White and I became friends at school, and her family welcomed me like a long-lost cousin.
In my family, it was always important to place blame(责备、责怪)when anything had happened. From the time we were little, my sister, brothers and I told on(告发)each other. The Whites, however, didn’t worry about who had done what. The beauty of this was driven home to me the summer Jane died.
In July, the White sisters and I decided to take a car trip from their home in Florida to New York. The two older sisters, Sarah and Jane were college students, and the youngest, Amy, had recently turned 16. Proud of having a new driver’s license, Amy was excited about practicing her driving on the trip.
The big sisters shared the driving of Sarah’s new car during the first part of the trip, but when they reached less crowded areas, they let Amy take over. Amy got behind the wheel. She came to a crossroads with a stop sign. No one would ever know whether she was nervous or just didn’t see the sign, but Amy didn’t stop at the crossroads and a large truck ran into our car.
Jane was killed at once. I was slightly injured. The most difficult thing that I had ever done was to call the Whites to tell them what happened. Painful as it was for me to lose a good friend, I knew that it was far worse for them to lose a child.
When Mr. and Mrs. White arrived at the hospital, they found their two daughters sharing a room. Sarah had a few cuts on her head; Amy’s leg was broken. They hugged all and cried tears of sadness and of joy at seeing their daughters. They wiped away the girls` tears and made a few jokes at Amy as she learned to use her crutches(拐杖).
To both of their daughters, and especially to Amy, over and over they simply said, “ 5 . ”
I was astonished. No blame. No accusations(控诉,指责).
Later, I asked the Whites why they never talked about the fact that Amy was driving and had run a stop sign. Mr. White said, “Jane is gone and we miss her terribly. Nothing we say or do will bring her back. But Amy has her whole life ahead of her. How can she lead a happy life if she feels we blame her for her sister’s death?”
They were right. Amy graduated from the University and got married several years ago. She is now a mother of two little girls of her own, the older named Jane.

【推荐3】If you dream of becoming a spaceman after you grow up, get started now! A spaceman needs a strong body and mind. See here what spacemen are able to do. They have many abilities that may make you amazed.
Spacemen are able to live upside down. They do this not just during sleep. They also do this when eating and going to the toilet. Before they fly into space, they have lots of practice. Each upside-down training lasts for 20 days.
Spacemen aren’t only drivers, but repairers and scientists. They have to know every part of the spaceship and how it works. If something goes wrong, they must know how to make it work again. Also, they do scientific experiments in space.
Spacemen know how to live in the wild. They take a knife, a gun and some dye (染料) with them into space. If they land in forests, the knife and the gun can protect them from wild animals. If they fall into the sea, the dye colours the water around yellow. This can help people find them easily on the sea.
Spacemen can’t get dizzy (眩晕的). A spaceship is not a plane. When it goes up, the extra gravity force can break people’s bones. Spacemen must have strong bodies for this. They can’t get a headache or be sick. With many things to take care of, they’ve got no time for sickness.
根据短文内容回答问题,每题答案不超过6个词。

【推荐1】As you know, homework is a big part of going to school. By doing homework, students can remember what they have learnt more easily. Moreover, they can use it more correctly. However, homework, sometimes, is much and hard. Luckily, here are some suggestions for you to make homework easy.
Plan the homework. Most middle school students have two or three hours of homework a night. If it is a day with heavy homework, you may need to spend even more time. It is a good idea to come up with some kind of homework schedule(进度表),especially if you are going to do sports or other activities after school.
Watch where you work. A bedroom, study or any room where you can get away from noise is good for you to do your homework. Don’t study on your comfortable bed if you want to do homework well, or you might fall asleep there.
Take a break. Most people’s attention (注意力) doesn’t last very long, so take some breaks while doing your homework. Sitting for too long but not having a rest will make you less productive (多产的) than if you stop to take a break regularly. Taking a 15-minute break every hour is a good way for most people to refresh themselves.
Get help when you need it. Sometimes even though you are listening carefully in class, some subjects seem too hard. The first person to ask for help is your teacher. He or she may be able to work with you before or after school and explain (解释) things more clearly. Your classmates may also be able to give you a hand. However, this might not give you the results you want. Lots of people understand something well but are not able to explain it.

The Silk Road is the name of different roads that long ago connected Europe, Africa and Asia. People reached these different places along these roads. Scientists believe people began to travel the Silk Road about 3000 years ago. By the time the Chinese silk trade became important in the world.The Silk Road covered almost 6500 kilometres. It spread from Rome to China, which is from the West to the Far East.
Traders travelling along the Silk Road carried silk, of course. They also carried and traded spices (香料), cloth, valuable stones and gold.
Along and around these ancient path(小路), have come many fascinating and mysterious stories
It is said that Roman soldiers (士兵) travelled through central Asia. They started to live somewhere near the ancient Chinese village of Liqian. Some of these Romans married local Chinese women and the story of blue-eyed villages of China was started.
During its busiest period, the Silk Road allowed people from many different cultures and countries to meet each other and mix. The Silk Road allowed the sharing of valuable goods and new ideas. These included people and trading goods from the Mediterranean, Persian, Magyar, Armenian, Bactrian, Indian and Chinese areas. All these peoples travelled the Silk Road, and they shared goods, stories, languages, and cultures.
In modern times, the old Silk Road routes (路线) are still used, but now they are crossed by trains instead of camels and horses. There is even a Silk Route Museum in Jiuquan in China. It has over 35,000 objects from all along the Silk Road. In this way, China protects the history of many countries and peoples.

【推荐3】①We do want help our family, friends and classmates when they’re having a hard time. But how can we help them out in right ways?
②Rachel Miller is a writer and she mentions some ways about (A) that in her book How to Be There for Yourself and Your People.
③Keep your focus on your friend. When a friend comes to you, it’s a good idea to help them forget their terrible experience. But if you want to tell them a similar experience, it’s not always welcome.
④If you do feel that your experience might be helpful to hear, Miller’s advice is to let your friend know that you went through something similar, but allow them to decide if they want to hear about it at the moment.
⑤Ask how you can best help your friend. You may not know what kind of help your friend wants. Just ask! Miller advises to try these questions: “What’s the best way I can help you right now?”, “Do you need someone to talk to?”, “Would you like my help?”, or “How are you feeling about the hard experience you’re going through?”
⑥ (B) _________ People may shy away from saying “I’m sorry” to the people in trouble, because you cannot feel the same way as them. But Miller says a real, honest “I’m sorry” can help to make your friend feel heard and accepted. “Sometimes there isn’t a perfect way to make people feel better,” she says. “But what you need to do is to say ‘You’re not alone. I’m with you. I’m so sorry it’s happening to you.’ ”
