Before the invention of hair dryer,vacuum cleaners were being used for the purpose of drying and styling hair. The early vacuum cleaners could draw in air as well as blowing air.So,towards the end of the 19th century,women used to dry their hair by using a vacuum cleaner.
In 1890,a French salon owner Alexander F.Godefroy invented the first hair dryer.It blew warm air.However,it was not widely used,mainly because of its large size.
The first convenient hand-held hair dryer used at home came up in 1920.It weighed over 2 lbs.However,it only produced 100 watts of power,which was not enough to dry the hair.After almost ten years came the gas-heated dryers that were widely used in barber shops.However,these dryers produced heat that was harmful to hair and the air from them made people sick,so they were soon gone.
Around the 1940s and 1950s,the helmet（头盔）style electric dryers came into being.Curly hairstyles were popular during that time.Therefore,women used curlers and sat under the dryers to set their curls.Later,the curly style began to drop,and so did the popularity of the helmet style electric dryer.
In the late 1950s,the first workable hair dryer was made.It had a hand-held dryer.It used only 300-400 watts. Ever since the 1950s,hand-held dryers have experienced many changes,in order to become quieter,lighter and smaller.However,how it works largely remains the same.The modem technology has made improvements to the hair dryer,reducing the heat damage to a person's hair.For producing shinier,smoother and healthier hair,dryers have been included with negative ion（负离子）technology that dries hair faster and with less heat.
1.What do we learn about the hair dryer invented by Alexander F.Godefroy?
A. It looked like a vacuum cleaner. B. It was once very popular.
C. It was inconvenient to use. D. It blew too hot air.
2.What was the disadvantage of the hair dryer invented in 1920?
A. It needed too much power. B. It couldn't be held by hand.
C. It was not easy to be carried around. D. It couldn't dry hair effectively.
3.What was the main purpose of including negative ion in dryers?

James Dyson, the inventor of the bagless vacuum cleaner, is now the wealthiest person in Briton after his company posted a record profit for 2018. But how did he make his fortune?
My father died when I was nine, and I remember doing the household chores to help my mother. I hated changing the vacuum cleaner bag and picking up things the machine did not suck up.
Thirty years later, in 1979, I was doing chores at home alongside my wife. One day the vacuum cleaner was screaming away, and I had to empty the bag because I could not find a replacement for it. With this lifelong hatred of the way the machine worked, I decided to make a bagless vacuum cleaner.
Easier said than done, of course. I didn’t realize that I would spent the next 15 years perfecting my design, a process that resulted in 5,127 different prototypes (设计原型). By the time I made my 15th prototype, my third child was born. By 2,627, my wife and I were really counting our pennies. By 3,727, my wife was giving art lessons for some extra cash, and we were getting further and further into debt. These were tough times, but each failure brought me closer to solving the problem.
I just had a passion for the vacuum cleaner as a product, but I never thought of going into a business with it. In the early 1980s, I started trying to get licensing agreements (许可协议) for my technology. The reality was very different, however. The major vacuum makers had built a business model based on the profits from bags and filters (过滤器). No one would license my idea, not because it was a bad one, but because it was bad for business.
That gave me the courage to keep going, but soon after, the companies that I had talked with started making machines like mine. I had to fight legal battles on both sides of the Atlantic to protect the patents (专利) on my vacuum cleaner. However, I was still in financial difficulties until 1993, when my bank manager personally persuaded Lloyds Bank to lend me $1 million. Then I was able to go into production. Within two years, the Dyson vacuum cleaner became a best-seller in Britain.
Today, I still view risk and the potential for failure as part of the process. Nothing beats the excitement of invention. Go out and brainstorm your ideas. You are not limited by any rules — in fact, the stranger and riskier your idea, the better.
1.Which of the following provided inspiration for Dyson’s invention?
A.The death of his father B.The scream of his wife
C.The hatred of homework chores D.The trouble the cleaner bag brings
2.Why was Dyson’s vacuum cleaner not accepted at first?
A.Because the vacuum makers profited from bags and filters.
B.Because Dyson’s vacuum cleaner still needed to be improved.
C.Because the major vacuum makers had updated their products.
D.Because Dyson’s vacuum cleaner didn’t get licensing agreements.
3.Dyson’s machine got into production _____________.
A.before the legal battles B.after becoming famous
C.upon applying for the patent D.in spite of financial difficulties
4.The author’s real purpose of writing the passage is to _______.
A.emphasize the necessity of brainstorming our ideas
B.explain the development of the vacuum cleaner
C.introduce Dyson and his vacuum cleaner
D.urge people to accept risks and failure

It just may be the world’s most costly vacuum cleaner (吸尘器). The price of CleanSpace One is eleven million dollars. But yet, it has a big job to do. Recently, researchers in Switzerland said they planned to build this new cleaning machine.
CleanSpace One will not be for use in homes or businesses. It will be shot into space to help remove thousands of pieces of
space junk floating around up there.Last year, we reported on the problem of space junk. Over time, many unused spacecraft have hit each other far above the Earth. Big pieces break into thousands of small pieces. Sometimes they fall back into the atmosphere (大气层) and burn
up. But when they do not, it creates big problems.Scientists fear that if something is not done to remove these objects, it may soon become too dangerous to send people and machines into space. There is a large chance that they might hit some of this junk. So that is why the Swiss researchers are developing the new machine.
CleanSpace One is not really a vacuum cleaner. It will not be used to take away space junk. But scientists plan to move it close to an old satellite that is no longer being used. Then a claw-like instrument will catch the satellite, and force it back through the atmosphere. There, the satellite will be destroyed by the heat of friction (摩擦) with the air.
Researchers say that all they need to do is slow down the speed of some of these unwanted objects. Once they begin to move more slowly, they will fall back to the Earth. There is little chance that they will fall through the atmosphere and harm the people or things below.
1.Space junk is created when ____________.
A. unused spacecraft hit each other
B. people in space throw away rubbish
C. a new spaceship is sent up
D. an old spaceship creates friction with the air
2.What’s the danger of space junk?
A. It will pollute space. B. It will hurt people on the Earth.
C. It will hit a spaceship. D. It will burn in the atmosphere.
3.Unwanted objects will fall back to the Earth when _______ .
A. they are made to move slowly B. they meet other objects in space
C. they are not used for years D. they are near the atmosphere

Even thousands of years before the “selfie(自拍)” was invented, people were concerned with the image of themselves they presented to the world. The rulers of ancient Egypt had artists carve portraits of them to decorate their tombs and preserve their images even after death.
King Tutankhamen lived more than 3,000 years ago. He ruled ancient Egypt for 10 years, until his death at age 19. “King Tut” remained practically unknown in the modern world until 1922, when scientists discovered his tomb, buried and forgotten for centuries. The treasures inside gave the world the first detailed picture of ancient Egyptian life.
The ancient Egyptians worshipped(崇拜) many gods. They also believed that all people had a life spirit, called “ka” that needed a place to live after the body died. Tombs inside huge pyramids protected the pharaohs'(法老) ka. The ka could also exist in portrait sculptures like the one of a seated Hatshepsut. The wife of a pharaoh, Hatshepsut took on the role of king after her husband died. Carved from limestone, this Life-size sculpture shows the life force of Hatshepsut's ka. The artist suggests Hatshepsut's strength by placing her feet firmly on the ground and resting her hands on her knees in a firm, powerful pose.
Viewers are meant to look at the sculpture of Hatshepsut from a frontal angle only. But artist Thutmose created his portrait of Queen Nefertiti as a sculpture in the round, meaning viewers should observe it from many points of view. The work is a highly realistic portrait of a queen who ruled beside her husband, a pharaoh. Painted with delicate(精细的) features, the impressive colors in her portrait resemble the makeup Nefertiti probably wore in life.
Long before any of these portraits were created, a huge creature with a lion's body and a human head stood guarding in Egypt's Valley of the Kings. No one knows who created the Great Sphinx, or why, but it is said to resemble an early pharaoh. Carved out of solid rock on a larger-than-life scale, it is possibly the oldest and most imposing portrait in the world.
1.The artist presents Hatshepsut's strength mainly through the ________ of the sculpture.
A.gesture B.material
C.color D.size
2.According to the passage, the portrait of Nefertiti was ________.
A.imaginative B.lifelike
C.threatening D.abstract
3.The Great Sphinx might be ________.
A.a king of animals
B.a guard as brave as a lion
C.a portrait of an early pharaoh
D.a creature owned by a pharaoh
4.What's the passage mainly about？
A.The oldest selfie in the world.
B.Some powerful kings in Egypt.
C.Some portraits of kings in some countries.
D.Some portrait sculptures of ancient Egyptian rulers.

Sharks have been swimming in the ocean for millions of years. They were on Earth even before dinosaurs! At the top of the world’s ocean’s food chain, sharks help keep the population of other ocean animals in balance. A large drop in the number of sharks can cause serious problems for all ocean animals. Saving sharks makes sense!
Many people are afraid of sharks. But most sharks are harmless. Only a small percentage of sharks are known to attack humans. It adapt(适应) well to new habitats and eat whatever is available. However, today, sharks are in trouble. Nearly one-third of the 400 shark species are in danger of extinction, largely due to over-fishing. Each year, tens of millions of sharks are caught and killed just for their fins(鳍). The fins are used to make shark fin soup.
Humane Society International (HSI) joined with the Jane Goodall Institute’s Roots and Shoots program and Beijing Zoo to protect sharks. An exhibit at the zoo, “the Price Behind the Taste-----Protect Sharks. Don’t Eat Shark Fins”, was designed to tell people that shark finning is cruel and unnecessary. It’s hoped that the activity will help put an end to the practice.
Shark fin soup is also eaten in the United States. In fact, the numbers of some shark species in US waters have dropped 90 percent in the last 30 years. To slow the fall, laws against the sale of shark fins have been passed in several states, including Hawaii, Oregon, Washington, and California.
1.What does the first paragraph mainly tell us?
A. Ocean animals are at the top of the food chain.

2.According to paragraph 2, sharks are in trouble because ______.
A. they often attack humans.

D. their habitat is being destroyed.
3.The underlined part “the practice” in Paragraph 3 refers to _______.

B. It’s illegal to eat shark fin soup in the United States.
C. Most sharks are not interested in a human for dinner.
D. Sharks are very particular about their habitats and food
