7 A2 slime

CHAPTER 1 We Love Slime! WHO LIKES SLIME? EVERYBODY! SLIME IS A WONDERFUL THING! You can pull it; you can push it. You can put your fingers into it. It's lots of fun to play with. You can even make your own slime at home. Here's how. You need: White glue Water Borax powder (you can buy this in a grocery store) Two plastic cups Fill the first cup with water. Add some borax powder. Mix. Put some glue in the second cup. Add some water. Mix. Now take a little of the mix from the first cup and add it to the second cup. Mix well. Wait 30 seconds. Excellent! You have SLIME!

第1章我们爱黏液！谁喜欢黏液？ 大家好!黏液是一种奇妙的东西！你可以拉它；你可以推它。 你可以把手指伸进去。 玩起来很有趣。 你甚至可以在家自制黏液。 这是如何。你需要：白胶水硼砂粉（你可以在杂货店买到）两个塑料杯第一个杯子装满水。 加一些硼砂粉。混合。 在第二个杯子里放一些胶水。 加点水。混合。现在从第一杯中取一点混合物，加入到第二杯中。 拌匀。等30秒。 太好了!你有粘液！

Adults like slime, too! A British TV show called Tiswas put people in a glass box and threw slime all over them. The people watching TV loved it! We like eating slimy things, too. Think of sea animals like oysters. Some people eat uncooked oysters, and they feel very slimy in your mouth! The French are famous for cooking slimy animals like snails, and they like frogs' legs, too. Then there's okra, a green vegetable from Asia and Africa. It gets slimy when you cook it because it has mucilage inside it— a mix of protein and sugar. Mucilage is plant slime. Mucus is animal slime.

成年人也喜欢黏液！一部名为《Tiswas》的英国电视节目把人放在一个玻璃盒子里，然后往他们身上扔黏液。 看电视的人喜欢它！我们也喜欢吃黏糊糊的东西。 想想牡蛎这样的海洋动物。 有些人吃生蚝，它们在你嘴里感觉很黏！法国人以烹饪蜗牛等黏糊糊的动物而闻名，他们也喜欢青蛙腿。 还有秋葵，一种来自亚洲和非洲的绿色蔬菜。 当你煮它的时候，它会变得粘稠，因为它里面有粘液——一种蛋白质和糖的混合物。 粘液是植物黏液。粘液是动物的黏液。

CHAPTER 2 Is That Water? No, It's Snot! YOU FEEL BAD. YOU SNEEZE A LOT. YOU HAVE A COLD! Having a cold means one thing for certain: snot! What is snot? Is it water that comes out of your nose? No, it's mucus. You can't feel it, but your body is making mucus all the time. Inside your nose, there are small hairs. Every time you breathe in, these hairs catch dirt and germs and stop them from going into your body. But sometimes, the germs get through and grow, and you get a cold. The cold makes the skin on the inside of your nose swell. At the same time, your body makes more mucus to wash the germs away. This mucus mixes with dirt and germs and becomes snot.

第二章那是水吗？不，是鼻涕！你感觉很糟糕。 你经常打喷嚏。你感冒了！感冒肯定意味着一件事：鼻涕！鼻涕是什么？ 是从你的鼻子里流出来的水吗？ 不，这是粘液。你感觉不到，但你的身体一直在分泌粘液。 在你的鼻子里面，有一些小毛。 每次你吸气时，这些毛发会吸附灰尘和细菌，阻止它们进入你的身体。 但有时，细菌会穿透细菌生长，你就会感冒。 寒冷会使你鼻子里面的皮肤肿胀。 与此同时，你的身体会分泌更多的粘液来冲走细菌。 这种黏液与污垢和细菌混合在一起就变成了鼻涕。

We all have mucus running between our noses and throats, and that's nothing to worry about. It means our bodies are working correctly. But snot can be nasty. It is thicker than mucus. That's why it's more difficult for you to breathe when you have a cold. What should we do when we have snot in our noses? First of all, look at the color. Does it have any color at all? No? Then that's good. You're normal and healthy. Yellow or green snot isn't so good. Your body is fighting germs, and when it is fighting, snot changes color. The best thing to do now is to blow your nose. Not everyone does, though. Some people put a finger up their nose and pull snot out— it's called "picking your nose." Don't pick your nose in front of other people. It's not polite.

我们的鼻子和喉咙之间都有粘液，这没什么好担心的。 这意味着我们的身体工作正常。 但鼻涕可能很脏。它比黏液厚。 这就是为什么你感冒的时候呼吸会更困难。 当我们的鼻子里有鼻涕时，我们该怎么办？ 首先，看看颜色。 它有颜色吗？ 没有?那很好。你很正常很健康。 黄色或绿色的鼻涕都不太好。 你的身体正在与细菌作斗争，当它战斗时，鼻涕会改变颜色。 现在最好的办法就是擤鼻涕。 但并不是每个人都这样。 有些人把手指伸进鼻子里，把鼻涕拔出来——这叫做“挖鼻子”。 不要在别人面前挖鼻孔。 这是不礼貌的。

In the 1920s, a company called Kimberly-Clark started making things called "facial tissues." They were small pieces of soft paper for women to take off their makeup. They called them Kleenex. The company showed pictures of movie stars using them, and women began to buy them. In the summer of 1927, a man who worked at the Kleenex company had hay fever. Hay fever is something that makes you sneeze a lot, usually in the spring or fall. You get it from breathing pollen. So what did he do? He used Kleenex facial tissues to blow his nose! Soon, facial tissues weren't just for women and movie stars. Men and children used them, too. Now you can buy tissues in almost every store.

20世纪20年代，一家名为金佰利的公司开始生产一种名为“面巾纸”的东西。 它们是女人用来卸妆的小纸片。 他们称之为舒洁。该公司展示了电影明星使用它们的照片，女性开始购买它们。 1927年夏天，一个在舒洁公司工作的人得了花粉热。 花粉热是一种让你经常打喷嚏的疾病，通常发生在春天或秋天。 你会因为呼吸花粉而感染。 那么他做了什么？他用面巾纸擦鼻子！很快，面巾纸就不仅仅是女性和电影明星的专利了。 男人和孩子也使用它们。 现在你几乎在每家商店都能买到纸巾。

Do animals sneeze? Animals don't use tissues, but they do sneeze. Sneezing is something we can't easily stop. It's a reflex action. And animals sneeze for some of the same reasons we do sneezing takes away the things that irritate our noses, like dirt and germs. That's why sneezing sometimes feels nice. But animals sneeze into the air, not into a tissue. This means that germs can get out into the air and make other animals sick. Some animals, iguanas, for example, sneeze a lot. Iguanas don't get more colds than other animals. They sneeze to get salt out of their bodies. On the Internet, you can see lots of animals sneezing even an elephant. That's a big sneeze, so watch out!

动物会打喷嚏吗？动物不用纸巾，但它们会打喷嚏。 打喷嚏是我们无法轻易停止的。 这是一种反射动作。动物打喷嚏的原因和我们打喷嚏的原因是一样的，它可以带走刺激我们鼻子的东西，比如灰尘和细菌。 这就是为什么打喷嚏有时感觉很好。 但动物是对着空气打喷嚏，而不是对着纸巾打喷嚏。 这意味着细菌可以传播到空气中，使其他动物生病。 有些动物，例如鬣蜥，经常打喷嚏。 鬣蜥并不比其他动物更容易感冒。 他们打喷嚏是为了排出体内的盐。 在互联网上，你可以看到很多动物打喷嚏，甚至大象。 那是一个很大的喷嚏，所以小心！
