You might have seen beautiful rainbows in the sky before.They form when sunlight falls on water drops in the air.But in fact，moonlight can also create rainbows in the same way.They are called "moonbows".They are similar to rainbows，but they are created by moonlight instead of direct sunlight.
Moonbows are rarer than rainbows.Different weather and astronomical （天文学的）conditions have to be just right for moonbows to be created.
The moon has to be very low in the sky — only 42 degrees from the horizon （地平线）.The moon period has to be a full moon or nearly full.The sky must be very dark for a moonbow to be watched clearly — any bright light can obscure it.Water drops must appear in the air in the opposite direction of the moon.
Moonbows appear on the opposite side of the moon and usually look white to the human eye.This is because their colors are not bright enough to be noticed by the human eye.It is possible，however，to view the colors in a moonbow using long exposure （长时间曝光）photography.
Moonbows more often appear in some locations around the world.Most of these locations usually have waterfalls，which create thin fog in the air.Some of these locations are the Yosemite National Park in California and Cumberland Falls State Resort Park in Kentucky，US；Victoria Falls on the border of Zambia and Zimbabwe；and Waimea in Hawaii，US.
Moonbows do really happen.So at a certain time and a certain place，when a moonbow happens to appear，you can't miss it if you' re right there.

There are many deserts（沙漠）on the earth.And the following are some facts you may find interesting.
What are deserts like？
Deserts can be hot and dry places.Rain may not fall there for months or years.Some deserts are sandy and stony（多石的）.Deserts can also be very windy places.The wind can change the shape of the deserts.It moves sand around from place to place.
Temperatures in the desert can vary enormously（非常）.During the daytime，the temperature may reach 40℃even in the shade（阴凉处）.At night deserts can become very cold.In winter there may even be a frost（霜冻）in the early morning.
Living in the desert
The camel is sometimes called "the ship of the desert".It stores food in its hump （驼峰）and can go for days without water.It has large feet which help it not to fall into the soft sand.Its long eyelashes（睫毛）keep out the sand during sandstorms.
An oasis is an area of the desert where water may be found.The water may be in pools or under the ground.People and animals visit an oasis for water and food.Plants grow at an oasis.Some farmers are able to grow crops here.
The Arabian Desert
The Arabian Desert lies between the Red Sea and the Arabian Gulf.In some parts of the desert，it is too hot for people to live.Oil was discovered under parts of the desert and in the Arabian Gulf.This oil has made some countries in the area very rich.Much of the money has been spent building fine cities with lovely parks and lakes，and people live a comfortable life there.

We see humans all around us.But when was the first human seen？Early humans did not leave behind any written records.However，they left behind many paintings on the walls of the caves（洞穴）where they lived.These paintings tell about their life，and we know these early humans walked on four limbs（四肢）like apes（猿）.Also，they did not live at one place but moved from place to place in search of food and water.
Without any tools，early humans used stones，bones of animals，and sharp pieces of wood to dig，hunt and cut their food.They also used these to protect themselves from animals.Since stones were used to make tools，this age was called Stone Age.
With time going，tools made of bones and stones were replaced with metal（金属的）ones which were stronger，sharper，and long﹣lasting.Metals were also used for farming and making knives.Copper（铜）was the first metal to be used.
The first fire that early humans noticed was natural fire caused by lightning（闪电）.With fire，early humans could light up dark caves.They could keep themselves warm during cold weather and cook meat.Also the fire could drive animals away.
Early humans noticed new trees growing from the seeds（种子）that fell to the ground from the fruits.This gave them the idea that they could make their own food by planting seeds，which led to farming.With the beginning of farming，early humans began to settle down（定居）.They moved out of the caves and lived on farms and near their fields together，then the first villages came up.
Raising animals was a big event in human history that changed the life of early humans.The wild dogs were probably the first animal to be raised.As time went，goats，sheep，cows，donkeys，and horses were kept，too.This led to herding（畜牧业）.Milk，meat and wool came from these animals.

Lima，the capital of Peru，is located in the central coastal part of the country，overlooking the Pacific Ocean.With a population of more than 9 million，Lima is one of the largest cities and the only capital in South America that faces the ocean.
Lima has a long history.The lost Inca civilization ，is thought to be a mystery.There are many museums，where you can learn：how the ancient American Indians founded the Inca Empire and built Machu Picchu，a famous ancient city in the Andes Mountains；what happened in 1532 and why over 90% of Peruvians speak Spanish.Visiting the historic center，a World Heritage Site you may find you are communicating with both the past and the present.
Lima is also a place where you can find the lifestyles and fashions，created by its people and culture.You will see Peruvian clothes，dances，and taste their delicious foods and drinks.You can see buildings in different styles，enjoy the fantastic sunset over the ancient ruins，climb the mountains，fly over the ocean，or sit in the restaurants and bars to experience Peruvians' relaxing life.
You may have heard "It never rains in Lima. " In fact，the special geographic feature makes it not as dry as it is said to be and it is warm all year round.Though it seldom rains in summer，it sometimes drizzles on early winter mornings.The drizzleand the wet air "water" the ground，which makes the crops and the plants grow.Moreover，modern technology helps to bring water from the snow and ice on the top of the Andes （over 6，000 m high）for the city to use.People there never waste water.

Have you ever entered a tropical rainforest（热带雨林）？Rainforests make up only a small part of the Earth's surface，about six percent，but there are more kinds of tees than any other area in the whole world.
Tropical rainforests are in Africa，Asia，Central and South America，Australia，and on the Pacific islands.The largest tropical rainforest is the Amazon（亚马逊）Rainforest in South America，which covers 1.2 billion acres，or almost five million square kilometres.The second largest rainforest is in Western Africa.
Rainforests provide us with many things.In fact，the Amazon Rainforest is the "lungs of our planet" because it produces 20%of the world's oxygen （氧气）.One fifth of the world's fresh water is also found in the Amazon Rainforest.Furthermore，one half of the world's species of animals，plants and insects live in the Earth's rainforests.80% of the food we eat first grew in the rainforest.25%of the drugs we take when we are sick are made of plants that grow only in rainforests.Some of these drugs are even used to fight and cure cancer.
There are four different levels of trees in a rainforest.The forest floor is the lowest layer full of animal life and receives the least amount of light.The under storey is the dark，cool environment under the leaves but over the ground.The canopy layer is the upper parts of most of the trees.The emergent layer contains a small number of very tall trees.
These different parts of a rainforest exist together to create an ecosystem for many animals，plants and human beings.

Marco Polo was born in Italy in 1254.When he was 17，he travelled along the Silk Road with his father，who wanted to do trade with the Chinese.Finally，they arrived in Beijing.They were guests at the Emperor's Palace.Although Marco was young，he was very clever and could speak four languages.The Emperor was impressed by him and they became friends.The Emperor asked Marco to help him and sent him to do many important jobs all over the country.
Marco was amazed by how great China was.He was impressed by the Emperor's Palace which he described as "The greatest palace that I've ever seen".The walls were covered with gold and silver and the hall was so large.
Marco was also attracted by lots of strange things in China.Marco was surprised to see Chinese people using paper money in the markets.In Europe，people paid for goods with gold and silver.He could not understand how people paid for food and valuable things with paper!He was also puzzled by the black stones people used to burn to produce heat.The black stones were coal，but Marco had never seen coal before!
After he served the Emperor for 17 years，in 1291，Marco returned to Italy.He had a lot of money then.A writer wrote down all the stories that Marco told him in a book called The Description of the World，which became one of the best﹣selling books in Europe.

The Arctic is home to over 21，000 kinds of animals and plants.Two thirds of it is the Arctic Ocean.In winter，it is completely covered with sea ice.In summer，nearly 50 percent of the sea is ice.
It's also home to about 4 million people，a group of whom are Inuit.Jim is an Inuit boy.At 6：30 am，he wakes up and gets ready to go to school in his fur coat.It keeps him warm in the freezing weather.Half an hour later，he gets to school on a ski or snowmobile.Some of his friends go by car instead.At 11 ：30 am，it's time for lunch.There's fish and other meat in his lunchbox.He sometimes eats them uncooked.These foods give him enough energy.Besides local food，some people eat Western food.At 5：00 pm，the snow outside makes everything bright，so he wears snow goggles on his way back home，or his eyes may be hurt badly by the strong light.From December to March，the sun never rises.However，it always shines in the sky during the summer.At 10：00 pm，he goes to bed.Sometimes he stays in an ice house called igloo.I looks cold but it's warm inside.Many local people live in houses made of wood.
The Inuit mainly make a living by hunting and fishing.Now，their life is greatly influenced by climate（气候）change.For example，many animals they hunt for food are disappearing.There is less food for the reindeer they keep，too.They face more terrible weather，such as snowstorms.Hunting becomes more dangerous.Hunters may accidentally fall into water if the ice becomes too thin.Actually，the temperature in the Arctic is 18℃ higher than it was 125 years ago.All Arctic ice may disappear during the summer in less than 100 years.

An exhibition（展览）about the Grand Canal（大运河）ended at the National Museum of China in Beijing on March lst.
The Grand Canal is more than 2，500 years old.It is made up of the Beijing-Hangzhou Grand Canal，the Sui and Tang Grand Canal，and the Zhedong Canal.At nearly 3，200 kilometers long，it is the world's longest man﹣made waterway.It has influenced the development of Chinese economics（经济）and culture for hundreds of years.
Before it was built，people in ancient China used horses and oxen（公牛），or simply traveled on foot，to trade goods（货物）.It was impossible to transport（运输）large﹣sized goods.After the Grand Canal connected the north and the south，business and cultural exchanges were able to develop further.
In fact，the Grand Canal played an important role in the building of the Forbidden City（紫禁城）.Materials from different parts of the country were sent to Beijing through the canal，including bricks（砖）fired in Shandong and Jiangsu and wood cut in Hunan.People even owe the beginning of Beijing duck to the canal.White lake ducks in the south were shipped to Beijing.They were then kept to make Beijing duck.People from all walks of life preferred to get together along the canal.They shared their experiences，traditions and culture with others.
