Today, I want to tell you about a little invention made. It's called the books holder. I love reading, but sometimes I find IT hard to hold a book for a long time. My arms got tired and I had to stop reading the rest. The problem made me think about inventing a book holder. Here was my invention process. First I drew a simple design on a piece of paper. Then I collected some materials, including an old box with really thick paper in a clip, which is a small, hard object to hold things together. Finally, I glued the pieces of paper cut from the box together and put the clip to the top. I opened my book and place the book on IT. The book was held by IT perfectly. I made IT. Now I just put the book holder on my desk when I want to read, I don't have to use my arms. I'm really proud of my little invention. It's not very beautiful or perfect, but IT really helps me enjoy reading more. Hello everyone, i'm teddy. Today, I want to tell you about a little invention I made. It's called the book holder.

Long long ago,people used different ways to store food.They kept food in cold water,underground rooms,or iceboxes.Iceboxes were wooden boxes with blocks of ice inside.However,ice melted quickly,and food still went bad easily.People needed a better way to keep food cold. Ⅷ -‹#›- Unit 5　单元练习 Ⅰ Ⅱ Ⅲ Ⅳ Ⅴ Ⅵ Ⅶ Ⅷ Ⅸ Ⅹ In the early 1800s,scientists discovered that some chemicals could absorb heat and make the air cooler.This idea led to the first fridge machines.In 1834,an American inventor named Jacob Perkins built a machine that used gas to cool things.It was the first step towards the modern fridge. Ⅷ -‹#›- Unit 5　单元练习 Ⅰ Ⅱ Ⅲ Ⅳ Ⅴ Ⅵ Ⅶ Ⅷ Ⅸ Ⅹ Later,in 1876,a German engineer named Carl von Linde created a better fridge system using a special gas.His invention made it easier to produce cold air.However,these early fridges were too big and expensive. Ⅷ -‹#›- Unit 5　单元练习 Ⅰ Ⅱ Ⅲ Ⅳ Ⅴ Ⅵ Ⅶ Ⅷ Ⅸ Ⅹ In the 1920s,companies started making smaller and safer fridges for homes.They used a chemical called Freon,which wasn’t bad for people.By the 1930s,many families could afford fridges,and they became popular. Ⅷ -‹#›- Unit 5　单元练习 Ⅰ Ⅱ Ⅲ Ⅳ Ⅴ Ⅵ Ⅶ Ⅷ Ⅸ Ⅹ Over time,fridges improved.They became more energy-efficient.Today,fridges come in many sizes and styles,helping people store food safely. Thanks to the hard work of scientists and inventors,we now have a convenient way to keep our food fresh.

At home,Jane found her mother working on the computer.Jane’s mother was sitting under a bright light.“Oh,my eyes hurt,” said her mother.Jane had an idea.Many people could not see their computer screen well in bright light.This problem needed an invention! Ⅷ -‹#›- Unit 5　单元练习 Ⅰ Ⅱ Ⅲ Ⅳ Ⅴ Ⅵ Ⅶ Ⅷ Ⅸ Ⅹ For the rest of the week,Jane made screen covers from different materials.She tried each one on her mum’s computer screen.Some materials were too heavy.Some were too thin.After trying many different things,Jane found the best material. On Friday,Jane brought her invention to school.Her invention was very small.It did not look very interesting.“Maybe the other kids will laugh at it,” thought Jane.Mr Brown asked everyone to talk about their inventions. Ⅷ -‹#›- Unit 5　单元练习 Ⅰ Ⅱ Ⅲ Ⅳ Ⅴ Ⅵ Ⅶ Ⅷ Ⅸ Ⅹ At last,it was time for Jane to show her invention.She put her special cover on top of the computer screen.She turned on the computer.The sun was shining through the window,but everyone could see the screen. “That is wonderful!” said Mr Brown.“Where did you get the bright idea for this?” Ⅷ -‹#›- Unit 5　单元练习 Ⅰ Ⅱ Ⅲ Ⅳ Ⅴ Ⅵ Ⅶ Ⅷ Ⅸ Ⅹ “I saw a problem,” said Jane.“It took some work to find the best way to solve the problem,but I made it.” “Small problems can lead to great inventions,” said Mr Brown.“You win our invention competition,Jane.” Ⅷ -‹#›- Unit 5　单元练习 Ⅰ Ⅱ Ⅲ Ⅳ Ⅴ Ⅵ Ⅶ Ⅷ Ⅸ Ⅹ ( )67.What is Paragraph 2 mainly about?

D Ⅷ -‹#›- Unit 5　单元练习 Ⅰ Ⅱ Ⅲ Ⅳ Ⅴ Ⅵ Ⅶ Ⅷ Ⅸ Ⅹ E ①How do we know the time?A clock,a watch or a mobile phone can help us.However,many years ago there were no clocks and knowing the time was not so easy.Over the centuries people have developed different ways of telling the time. Ⅷ -‹#›- Unit 5　单元练习 Ⅰ Ⅱ Ⅲ Ⅳ Ⅴ Ⅵ Ⅶ Ⅷ Ⅸ Ⅹ ②About 5,500 years ago,the Egyptians invented the sun clock.This was a tall stone building.Its shadow showed the movement of the sun.So people were able to know midday.The Egyptians made a sundial(日晷) about 3,500 years ago.It was smaller than the sun clock and could let people know the time for half a day.On cloudy days or at night it was impossible to tell the time with a sun clock or a sundial.Water clocks were the first clocks not to use the sun.The idea is simple.Water moves from one bottle to another.When the water reaches a certain level,it shows the hours.The Egyptians used water clocks about 3,400 years ago.These clocks were popular in the Middle East and China.But they failed to make people know the exact time. Ⅷ -‹#›- Unit 5　单元练习 Ⅰ Ⅱ Ⅲ Ⅳ Ⅴ Ⅵ Ⅶ Ⅷ Ⅸ Ⅹ ③In the 13th century,the mechanical clock was invented.This was more exact,but it was expensive to make one.In 1927,the first quartz(石英) clock was developed.Clocks became cheaper to make.It was also cheaper for ordinary people to own a clock.More recently,in 1956,came the digital clock.And nowadays satellites(人造卫星) send our mobile phones the exact time,down to the second. Ⅷ -‹#›- Unit 5　单元练习 Ⅰ Ⅱ Ⅲ Ⅳ Ⅴ Ⅵ Ⅶ Ⅷ Ⅸ Ⅹ ④There has been a lot of progress in timekeeping.Clocks are always changing but some things never change.Many of us still have trouble getting out of bed on time and not being late for school or work.

Ⅷ -‹#›- Unit 5　单元练习 Ⅰ Ⅱ Ⅲ Ⅳ Ⅴ Ⅵ Ⅶ Ⅷ Ⅸ Ⅹ The robotic dog needs to check a 1,100 kilometre-long power line.It is a part of a long power line.The long power line totally runs 3,284 kilometres from northwest China’s Xinjiang to the eastern province of Anhui.The “electric highway” is longer than any other power line in the world. Ⅷ -‹#›- Unit 5　单元练习 Ⅰ Ⅱ Ⅲ Ⅳ Ⅴ Ⅵ Ⅶ Ⅷ Ⅸ Ⅹ There are not enough workers at the power station.So it is difficult to keep the power station running well.But now robots have begun to change the condition.In Xinhe,a town in Chizhou,Anhui,which is surrounded(环绕) by mountains,a white drone began its task in the mountains.Within half an hour,it has completed its 80-kilometre checking task. Ⅷ -‹#›- Unit 5　单元练习 Ⅰ Ⅱ Ⅲ Ⅳ Ⅴ Ⅵ Ⅶ Ⅷ Ⅸ Ⅹ The high mountains make work quite difficult and dangerous.Drones provide an effective way,thanks to their high speed.Firefighters at another power station also use a robot.The robot can help them find fires as soon as possible. Ⅷ -‹#›- Unit 5　单元练习 Ⅰ Ⅱ Ⅲ Ⅳ Ⅴ Ⅵ Ⅶ Ⅷ Ⅸ Ⅹ In a word,robots have been used in many different fields.They can take the place of humans to do many dangerous jobs.They will certainly have more uses in the future.And we expect that human beings will invent more robots and make better use of them.
