21、How fit are your teeth? Are you lazy about brushing them? Never fear: An inventor is on the case. An electric toothbrush senses how long and how well you brush, and it lets you track（跟踪） your performance on your phone.
The Kolibree toothbrush was exhibited at the International Consumer Electronics Show in Las Vegas this week. It senses how it is moved and can send the information to an Android phone or iPhone via a Bluetooth wireless connection.
The toothbrush will be able to teach you to brush right (don’t forget the insides of the teeth!) and make sure you’re brushing long enough. “It’s kind of like having a dentist actually watch your brushing on a day-to-day basis,” says Thomas Serval, the French inventor.
The toothbrush will also be able to talk to other applications on your phone, so developers could, for example, create a game controlled by your toothbrush. You could score points for beating monsters among your teeth. “We try to make it smart and fun,” Serval says.
Serval says he was inspired by his experience as a father. He would come home from work and ask his kids if they had brushed their teeth. They said “yes,” but Serval would find their toothbrush heads dry. He decided he needed a brush that really told him how well his children brushed.
The company says the Kolibree will go on sale this summer, from $99 to $199, and the U.S. is the first target market.
【1】All of the following statements are wrong except ____________.
A. It can track users’ school performance.
B. It can sense how users brush their teeth.
C. It can check users’ fear of seeing a dentist.
D. It can help users find their phones.
【2】What can we learn from Serval’s words in Paragraph 3?
A. You will find it enjoyable to see a dentist.
B. You should see your dentist on a day-to –day basis.
C. You’d like a dentist to watch you brush your teeth every day.
D. You can brush with the Kolibree as if guided by a dentist.
【3】What can we infer about Serval’s children?
A. They were unwilling to brush their teeth
B. They often failed to clean their toothbrushes.
C. They preferred to use a toothbrush with a dry head.
D. They liked brushing their teeth after Serval came home.
22、 All living organisms are uniquely adapted to the environment in which they live. Scientists are studying the design and the biological processes of these organisms to get ideas for products and technologies. This field of study is called biomimetics. Here are two examples.
Toucan Bills and Car Safety
Toucan usually has enormous bills. Scientists have found that the toucan's beak is designed to be both strong and light. The surface is made of keratin, the same material in human fingernails and hair. But the inside of the bill has a foam-like structure and is made up of a network of light, thin pieces of bone. It contains a lot of air, and some areas are hollow, not solid. This design makes the bill hard but very light.
The design of the toucan bill can be used to make cars and planes safer. Studies show that the beak's structure can absorb high energy impacts very well. Car body panels that mimic toucan bills may offer better protection to motorists involved in crashes.
Shark Scales and Swimsuits
Shark skin may look smooth, but it's actually rough. Sharks are covered in scales made from the same material as their teeth. Viewed up close, the scales actually look like tiny teeth. These scales protect the shark and help to keep it clean. They are also flexible and can turn or bend in the water. This movement reduces the waters drag on the shark and helps it to swim quickly.
Scientists discovered that the shortfin mako's scales vary in size and flexibility over its body. For instance the scales on the sides of the body are tapered — wide at one end and narrow at the other. They can turn up or flatten to adjust to the flow of water around the shark and to reduce drag.
Scientists believe that shark scales can inspire designs for machines that experience drag, such as airplanes. Designers are also getting ideas from shark scales for designing swimwear and coating ship bottoms.
【1】Why do car body panels copy the design of toucan bill?
A.To better protect passers-by. B.To reduce the injury to drivers.
C.To decrease the chances of crashes. D.To make cars lighter and easier to control.
【2】What product or technology is inspired by shark scales?
A.Coating for ship bottoms to run faster. B.Coating for airplanes to experience drag.
C.The panel that makes the plane safer. D.Swimwear that is smooth to keep itself clean.
【3】What’s the purpose of the text?
A.To present two innovative products. B.To introduce biomimetics by example.
C.To show the unique adaptations of animals. D.To discuss the link between humans and animals.
23、Paintings and sculptures can be a feast for the eyes of visitors to art museums, but today their viewing is also an unconventional treatment for people with mental illness.
Last month. a group of Canadian doctors started to write a new kind of prescription (处方), which gives patients free access to the Montreal Museum of Fine Arts (MMFA). There, they will have a “relaxing. revitalizing experience” looking at the museum’s collection.
Nathalie Bondil. the museum’s director general. believes that being in contact with culture and arts can help with wellbeing. “In the 21st century, culture will be what physical activity was for health in the 20th century.” she said.
Each prescription will allow not only the patients but also their families or friends to go with them. In the museum. the visitor can appreciate the artworks, and take part in a wide range of activities including drawing, sewing (缝纫) and making a sculpture with recycled materials.
The new treatment is said to be the first of its kind in the world. But there’s increasing evidence that the display of visual art, especially art depicting (描绘) nature, can have positive effects on people with depression, anxiety and self-respect problems.
In 2017, the UK’s All Party Parliamentary Group on Arts, Health and Wellbeing
(APPGAHW) also released a report stating that “the time has come to recognize the powerful contribution the arts can make to our health and wellbeing”.
Is it possible for art to improve overall health? We may not know the answer yet. But one thing is certain, more and more people today are persuaded by the idea that “art is good medicine”.
【1】What prescription did the group of Canadian doctors give to mental patients?
A．Get conventional treatment.

C．Join in some physical activities.
D．Appreciate paintings and sculptures.
【2】What can the patients do in the museum?
A．Depict nature.
B．Recycle sculptures.
C．Sew clothes.
D．Watch art workers.
【3】What do we know about the new treatment?
A．It can relieve depression.
B．Nothing can prove it right so far.
C．It was used before by some visual artists.
D．APPGAHW doubted its contribution in health.
【4】What is the best title for the passage?
A．Will MMFA be open to patients?
B．Is there a better medicine than art?
C．Is there a new treatment for artists?
D．Will fine arts improve mental health?
24、In the past ten years, many scientists have studied the differences between men and women. And they all got the same answer: The sexes(性别) are different, because their brains are different. And this, the scientists say, makes men and women see the world in different ways.
Boys, for example, generally are better than girls at mathematical ideas. Boys also generally are better than girls at the kind of hand and eye movements necessary for ball sports. Girls, on the other hand generally start speaking earlier than boys. And they generally(通常) see better in the dark than boys and are better at learning foreign languages.
What makes men and women better at one thing or another? The answer is the brain. The brain has two sides connected by nerve(神经) tracks. The left side generally is used for mathematics, speech and writing. The right side is used for artistic creation(创造) and the expression for emotions(情感). In men and women, different areas in each side of the brain develop differently. In boys, for example, it’s the area used for mathematics. In girls, it is the area used for language skills. Another interesting difference is that the two sides of a man’s brain are connected by a smaller nerves than the two sides of a woman’s brain are.
