I wonder if there is any girl or boy who does not like to see a rainbow in the sky. It is beautiful. There is a story, saying that whenever you see a rainbow you should run at once to the place where it touches the ground, and there you would find a pot of gold. Of course it is not true. Neither you could find gold, nor would you ever find its end. No matter how far you run, it always seems far away.
A rainbow is not a thing which we can feel with our hands as we can feel a flower. It is only the effect(结果) of light shining on raindrops. The raindrops catch the sunlight and break it up into all the wonderful colours which we see.
It is called a rainbow perhaps because it is made up of raindrops and looks like a bow(弓).
That is why we can never see a rainbow in a clear sky. We see rainbows only when there is rain in the air and the sun is shining brightly through the clouds. Every rainbow has many colours in the same order. The first or the top colours is always red, next comes orange, then green, and last of all, blue. A rainbow is indeed one of the wonders of nature.We can not feel _______with our hands.
| A．gold | B．a flower |
| C．a rainbow | D．a raindrop |
We can see a rainbow________.
| A．when it is raining heavily |
| B．when it is snowing |
| C．in a clear sky |
| D．When it becomes fine shortly after raining. |
Which of the follow is NOT right?
| A．A rainbow is always far away from us. |
| B．A rainbow is the effect of light shining on raindrops. |
| C．A rainbow is created by scientists. |
| D．A rainbow is one of the wonders of nature. |
The first color of a rainbow is always_______.
| A．yellow | B．red | C．green | D．blue |
"I spent my whole life doing one thing，" Gu Fangzhou once said.Known as "the father of sugar pills （糖丸）"，Gu passed away on January 2，2019.Eight months later，he received a national honorary﹣title （荣誉称号） "the People's Scientist" for his polio （脊髓灰质炎） research.
Gu Fangzhou，a famous medical scientist，was born in June，1926.Gu's family faced a difficult time with the sudden death of his father.He studied hard and finally entered Peking University as a medical student in 1944.After graduation，Gu made the decision to work to help improve public health.
In 1955，polio broke out in Nantong，Jiangsu Province.It paralyzed （使瘫痪） 1，680 people，mostly children aged below seven.It spread to neighboring areas and resulted in 466 deaths.Gu was asked to lead polio research in 1957. "At that time the only way to prevent polio was to invent a vaccine （疫苗），" said Gu.
In 1959 Gu succeeded in developing the first polio live vaccine.Later，he developed the "sugar﹣coated pill" vaccine in the early 1960s.It not only tasted better but was more affordable and easier to keep.To test the vaccine，Gu tried the vaccine in person and later his one﹣month﹣old son was vaccinated.This inspired his team to vaccinate their kids.They became the first group of people in China to try a polio vaccine. "If we don't believe in what we produce，how can others believe in it？" said Gu.
Gradually，the sugar﹣coated polio vaccine was made available in China.It saved millions of people，especially kids，from being disabled.In 2000，the World Health Organization （WHO） announced that China was already a polio﹣free country. "We feel satisfied.I can tell people that I tried my best，and your kids will no longer get polio，" said Gu. "That's all we hoped for. "

In 1987 a small company named Huawei was started in Shenzhen.After more than 30 years of development，the company has now beaten Apple and become the world's second largest maker of smartphones.It has also become the world's supplier （供应者） of 5 G.In China and even in the world，Huawei is a wonder.Although it started producing mobile phones not many years ago，it has become one of the most famous phone companies.

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.

The invention of barcodes（条形码）is based on a very simple idea.We only need to give each product a specific number and print it. （1） We could simply print the number itself.But this can cause problems.For example，an unclearly printed "seven" could look like a "one" to a computer.It's also true for "three" and "eight". （2） We need a better way of printing numbers so that they can be read correctly at high speeds.That's the problem barcodes solve.
Each number in a barcode is shown by seven blocks of the same size. （3） For example，the number "one" is shown in turn by two white stripes（条），two black stripes，two white stripes，and one black stripe.（4）
A barcode includes different parts and each one provides a specific meaning.The first part of a barcode tells you the country where the product was made.For example，690—692 is the barcode for China. （5） .The final part is about the product itself.This is how barcodes work.
|
A.Then computers can read it directly. B.All information can be shown by barcodes. C.The next part tells you who produced the product. D.And "nine" looks similar to "six" if you turn it upside down. E.Even if you turn it upside down，it isn't similar to any other number. F.These are colored either black or white to show the number zero to nine. |
Tangchang，a town in Chengdu，is well﹣known for cloth shoes.With over 20 types，Tangchang cloth shoes are strong，comfortable，breathable and friendly to the environment.In 2018，they were added to Sichuan's intangible cultural heritage list（非物质文化遗产名录）.
63﹣year﹣old Lai Shufang has spent over 40 years making Tangchang cloth shoes.Now she is a master.She said there are 32 steps to make a pair，but the most important step is making the soles.
Layers（层）of white cloth are glued together with flour paste（糨糊）. "To make good paste，we make it at a temperature of 85℃.If it's too low or too high，the paste will not work， "Lai said.Then the pasted layers are dried and cut into different shapes.After this，the layered cloth is beaten again and again until it is tight（紧实的）enough to make soles and upper parts.The next step is to shape the two parts and glue them together.But still the soles' edges look fluffy.Through repeated polishing and trimming，the fluffy edges（毛边）will become smooth.Then the cloth shoes are ready.
Lai's hard work touched her son Ai Peng.In 2015，Ai decided to leave his job and help his mother.He used Shu embroidery to make the shoes look more beautiful and opened a cloth shoe store online.He also set up shop windows to show the steps of making shoes，helping more people learn about the art of cloth shoes.
