Germs (细菌) are everywhere. You can't see them, but they are on your desk, on your computer, and even in the air! Like people, germs move around the world. They fly with us on planes. When food, clothes, and other things travel around the world, germs travel, too. Some germs are safe, but some are dangerous. Germs cause illnesses like colds and the flu.
Warmer Weather Brings Germs
The world's weather is changing. Cooler countries are getting warmer, so insects from hot countries can move there. Some of these insects, like mosquitoes, carry dangerous germs. These germs cause headaches, fever, and can even kill people.
Under Your Skin
Your skin protects you from germs. It stops some germs, but not all. They can enter your body when you eat, or when you have a cut. Germs are on your hands, too. They enter your body when you touch your eyes, nose, or mouth.
Fighting Germs
Your immune system (免疫系统) protects you, too. When germs get inside your body, your immune system finds and kills them. Special cells (细胞) move around your body and fight germs. They help you stay healthy. Other cells make antibodies(抗体). Antibodies help your body find and stop germs.
______ You should wash your hands with soap and water. Soap kills many germs, and water washes them away.
Your mom tells you to put on your hat and gloves. But as the cold winter season gets closer, it's so cold that even mom's advice does not work.
That means it's time to put on your qiuku! This is a kind of "thermal underwear(保暖内衣)" or long underpants that keep people warm in the coldest months of the year.
In Western countries, qiuku is usually known as long johns, but they aren't popular. Long johns in the US are usually two pieces, a long-sleeved(长袖的) shirt and long pants, worn under other clothing or sometimes even used as pajamas(睡衣).
Long johns first appeared in England during the 17th century. We call them long johns because the US boxer John L. Sullivan wore them while he boxed. But this is not a historical fact.
In the US, it gets quite cold and snowy in many places. And while parents often push kids to wear more clothes and long underwear, it's very special when young people actually(实际上) put them on.
Part of the reason might be because it's not very fashionable(时尚的) and another reason might be because people don't spend much time outside during the cold months. So they just deal with the freezing(冰冻的) temperatures when they have to leave the warm building. But in their parents' eyes, staying warm is more important than looking nice.
After a long day's study at school, you are very tired. So after school you go home to relax. When you get home, a robot greets you. He's happy to see you and helps you take your school things to your room. He listens to you talk about your school life and tells you a new joke. And he tells you to call your cousin and to say "Happy birthday". And then he helps you with your homework.
This is your future, and the robot's name is NAO. NAO has a small body, big eyes and a large head. He can walk and dance. He listens and talks, and he even learns and thinks for himself. His creators (创造者) predict that the robot will be in people's homes before 2040.
This $16,000 robot knows who you are. NAO can even expressemotions (表达情感). He is a self-guided robot. A self-guided robot can sense (感觉), think and act. Other robots might do two out of the three. For example, a robot might sense things using cameras and think using computers, but with no arms, he can't act. Another robot can move and sense things, but he can't think for himself. These aren't self-guided robots. But NAO can do them all.
If you are in Shanghai and want to throw away a cup of milk tea, be careful. You need to follow these steps: first, pour out any leftover into a wet waste bin; second, put the paper wrapper into a recyclable bin; third, throw the single—use cup and straw into a dry waste bin.
Sound complex(复杂的)? You'll have to get used to it. From July 1 on, people in Shanghai are required to sort (将……分类) their garbage according to strict rules。 Many other cities in China are planning to create similar garbage-sorting rules.
Why should we sort our garbage? The answer lies in the increasing amount of waste we are producing. Chinese cities produce over 200 million tons of waste each year, according to China Economic Net. Most of this waste is buried(填埋) in landfills(垃圾填埋场), which may pollute water and soil.. Moreover, we are running out of space for new landfills
In fact, more than half of our waste can be recycled. Recyclable garbage can be made into new materials, while wet garbage can be used to make gas, heat and fertilizer. But in order to recycle efficiently, we need to sort our garbage.
Can't garbage-processing companies do the sorting job for us? They can. But that requires a lot of work and costs lots of money. Things will become much easier if each of us can sort our own garbage. Besides, the troublesome task of sorting might encourage people to produce less waste. Do you still want to buy that milk tea?
① Because the amount of waste is increasing all the time.
② Because people can recycle more than half of their waste.
③ Because there are still some new landfills waste in China
④ Because most of buried waste may pollute soil and water
In nature, there are some animals that are at the top of their classes in smartness. Here are some examples.
African gray parrots (鹦鹉) are known for talking too much. They are excellent at copying humans and can form simple sentences.
When it comes to finding nuts, gray squirrels (灰松鼠) are professional (职业的). In one study, people hid several nuts to find out how squirrels solved the problem. The squirrels were quick learners, and even changed ways to get their rewards more quickly.
Chimpanzees(黑猩猩) are more than 98 percent similar to humans. They have a type of social learning which only the smartest animals can achieve.
Let's talk about teamwork! The army ants (蚂蚁) often join together to build a living ant tower. Researchers (研究者) discovered that they made decisions as a group.
Pigs are actually considered the fifth most intelligent animal in the world. They have excellent memory. They can find their way home from huge distances away.
A. Smart little piggies
B. Union (团结) is strength
C. Experts in nut searching
D. Humans' closest relatives
E. The cleverest talking birds
