U2 - How? Why?: Lesson 2 - Why Do People Laugh?Do you laugh every day? Most people do. Scientists say that people laugh about 17 times a day. That is a lot of laughter.In India, there are hundreds of laughter clubs. The people in these clubs get together every morning. First they stretch their hands above their heads. Then they pretend to laugh. Soon everyone is laughing naturally.People say they feel good after laughing together.Scientists believe that laughter is good for you. Why? For one thing, laughter is good exercise. When you laugh, you exercise many muscles in your body. Scientists say that one hundred laughs equals ten minutes of running. When you laugh, you also breathe deeply. This helps you relax. That's good for you, too.Why do we laugh? That is a hard question to answer. We know that people laugh more often in a group. They don't laugh very often when they are alone. Many scientists believe that we use laughter to connect to other people. Laughter helps us feel part of a group.In English, people say that laughter is the best medicine. Some think that laughter helps sick people get well. Do you think so, too?

Some people think it store water in its hump.This is not true.It stores food in its hump.The camel’s body changes the food into fat.Then it stores the fat into its hump.It doesn’t store the fat all over its body.Fat all over an animal’s body keeps the animal warm.Camels live in the desert.They do not want to be warm during the day.The desert is very hot.The camel gets hotter and hotter during the day.It stores the heat in its body because the nights are cool.The Arabian camel has one hump.The Bactrian camel of Central Asia has two humps.It also has long,thick hair because winters are cold in Centre Asia.There is a lot of sand in the desert.The camel has long eyelashes.The eyelashes keep the sand out of the camel’s eyes.Arabic has about150words to describe a camel. Many people who speak Arabic need all these words because the camel is very important to them.(185 words)The Polar BearThe polar bear is a very big white bear. We call it the polar bear because it lives inside the Arctic Circle near the North Pole. There are no polar bears at the South Pole.The polar bear lives in the snow and ice. At the North Pole, there is only snow, ice, and water. There is not any land. People cannot see the polar bear in the snow very well because its coat is yellow-white. It has a very warm coat because the weather is cold north of the Arctic Circle.This bear is three meters long, and it weighs450 kilos (kilograms). It can stand up on its back legs because it has very wide feet. It can use its front legs like arms. The polar bear can swim very well. It can swim 120 kilometers out into the water. It catches fish and sea animals for food. It goes into the sea when it is afraid.Some people want to kill the polar bear for its beautiful white coat. The governments of the United States and Russia say that no one can kill polar bears now. They do not wantall of these beautiful animals to die.(200 words)The HippopotamusThe hippopotamus, or hippo, lives in the hot part of Africa. It is a mammal. That is, its babies are born alive, and they drink milk from the mother's body.The hippopotamus is a large animal. It weighs four tons. Its stomach is seven meters long, and it eats only plants. It is a mammal, but it spends a lot of time in the water.During the day, it sleeps beside a river or a lake. Sometimes it wakes up. Then it goes under the water to get some plants for food. It can close its nose and stay under water for ten minutes. Its ears, eyes, and nose are high up on its head. It can stay with its body under the water and only its ears, eyes, and nose above the water. Then it can breathe the air.At night, the hippo walks on the land and looks for food. It never goes very far from the water.A baby hippo often stands on its mother’s back. The mother looks for food underwater. The baby rides on her back above the water.(184 words)Unit1 Lesson 5（05）The DolphinCan dolphins talk? Maybe they can't talk with words, but they talk with sounds. They show their feelings with sounds. Dolphins travel in a group. We call a group of fish a "school." They don't study, but they travel together. Dolphins are mammals, not fish, but they swim together in a school. Dolphins talk to the other dolphins in the school. They give information. They tell when they are happy or sad or afraid. They say "Welcome" when a dolphin comes back to the school. They talk when they play.They make a few sounds above water. They make many more sounds under water. People cannot hear these sounds because the sounds are very, very high. Scientists make tapes of the sounds and study them.Sometimes people catch dolphins for a large aquarium.(An aquarium is a zoo for fish.) People can watch the dolphins in a show. Dolphins don't like to be away from their school in an aquarium. They are sad and lonely.There are many stories about dolphins. They help people. Sometimes they save somebody's life. Dolphin meat is good, but people don't like to kill them. They say that dolphins bring good luck. Many people believe this.(201 words)。
中学生百科英语1-U2-L5 - How Do Many Hearing-Impaired People Talk
U2 -How? Why?: Lesson 5 -How Do Many Hearing-Impaired People Talk?Hearing-impaired people cannot hear sounds well. How do they "hear" words?Many hearing-impaired people use sign language. They talk with their hands. Two hearing-impaired people can talk to each other. They both use sign language. Sometimes a person who can hear interprets for hearing-impaired people. The person listens to someone talking, and then he or she makes hand signs.There are two kinds of hand signs. Some hand signs are for whole words. For example, there is one hand sign for the word love. There are hand signs for different actions, things, and ideas. Some of the signs are very easy, for example, the signs for eat, milk, and house. You can see what they mean. Others are more difficult, for example, the signs for star, egg, and week.The second kind of hand sign is fingerspelling. In fingerspelling, there is a sign for every letter in the alphabet. For example, to fingerspell the word love, a person makes four different signs. It is much slower to fingerspell, but it is useful for signing names and technical words. People can use both kinds of hand signs together.Each country has its own sign language. For example, American Sign Language (ASL) is very different from British Sign Language. Using signlanguage is almost like a dance. The whole body talks. Sign languages are beautiful. (223 words)。

中学生百科英语1-U2-L3 - Why Is the Sea Salty
U2- How? Why?: Lesson 3 - Why Is the Sea Salty?There is a lot of salt on the Earth, and it mixes very well with water.There is some salt in all water. Water on the land runs into lakes and rivers. The water from most lakes goes into rivers. These rivers run into the seas and oceans. They carry a little salt with them. Some of the ocean water moves into the air and clouds. It evaporates. Salt cannot evaporate. It stays in the ocean.The water in the oceans has more salt than the water in rivers. Ocean water is about 3.5% (three and a half percent) salt. Some seas have more salt than others.Some lakes do not have a river to carry the water and salt away. Some of the water evaporates, but the salt cannot. These lakes are very salty. There are two famous lakes like this. They are the Dead Sea in the Middle East and the Great Salt Lake in the state of Utah in the United States. They are much saltier than the Atlantic Ocean and the Pacific Ocean.中学生百科英语1-第二单元How? Why? 1。
中学生百科英语1-U2-L1-WhyDoWeYawn
中学生百科英语1-U2-L1-WhyDoWeYawnU2 - How? Why?: Lesson 1 - Why Do We Yawn?Bears yawn. Camels yawn. Most mammals yawn. Why do we yawn? No one really knows the answer.We do know that everyone yawns in the same way. First you open your mouth slowly. Your mouth stays open for about five seconds. Then you quickly close your mouth.We also know that yawning is contagious, or catching. When you see someone yawn, you yawn, too. Many people say that they yawn because they are bored or tired. This might be true. However, we know that people also yawn when they are excited or nervous. Olympic runners, for example, often yawn before a race. Why is that?Some scientists believe that yawning makes you more alert. When you yawn, you breathe more deeply. You also stretch the muscles in your face and neck. Maybe this makes you feel more alert.Scientists don't spend much time studying yawning. That is probably because yawning doesn't hurt. It is just something we do. (158 words)中学生百科英语1-第二单元How? Why? 1。

中学生百科英语1第2单元第二课到第4单元第一课文章翻译Lesson 1 Music and Behavior昨天你去哪了？你听到这些地方的音乐吗？有一个很好的改变，你没有。
今天，大多数商店和餐厅播放音乐。
你甚至可以在办公室或听到一个农家乐。
科学家认为，音乐影响人们的行为。
根据一些科学家，西方古典音乐（莫扎特，巴赫）的声音使人感到更加富裕。
当餐厅演奏古典音乐，人们花费在食物和饮料更多的钱。
当餐馆播放现代音乐，人们花更少的钱。
没有背景音乐，人们花费更少。
科学家们还认为，大声，快节奏的音乐让人们吃更快。
实际上人们咀嚼食物时更快的音乐变快。
有些餐馆在繁忙时间播放快节奏的音乐。
这让人们吃的快，赶快离开。
餐馆可以赚更多的钱这种方式。
一些科学家认为，音乐让你更好地思考和学习。
他们说，音乐可以帮助学生提高警觉。
诚然，人们学得更好时，心情很轻松。
而听音乐能帮助你放松。

Lesson 2 Blues and Jazz来自欧洲和美国人民作为奴隶的非洲人和美洲之前，在十九世纪。
这些非洲人带来了他们的音乐。
之后，美国南北战争（1861-1865），在美国非洲裔美国人不是奴隶。
他们的非裔美国人音乐名声大振。
它起源于南方，在路易斯安那州和密西西比州。
