三、阅读理解(本大题共15小题，每小题2分，共30分)
A
What’s going to happen in the future Will robots control our planet Will computers become smarter than us Not likely. But here are some things that scientists say are most likely to happen in 10 — 30 years from now, according to the BBC．Bionic (仿生的) Eyes
They are no longer something, only in a science fiction movie. People who are blind may have a chance to see things clearly—by wearing bionic eyes.
A blind eye can no longer sense sight, but a bionic eye can use a camera to “see” the environment and send information to the mind. Now the bionic eye only allows patients to see lights and unclear shapes. A bionic eye with very clear pictures could be just in a few years away.Digital Money
We used to pay with cash (现金) for everything we bought. Now we can use WeChat Pay or Alipay to shop. Money is spent without seeing it. That means we are already using digital money. People only need to take a mobile phone wherever they go. Using these ways is much easier than searching our pockets for change. It is also safer than carrying a lot of cash.
It is reported that people in Sweden completely stopped using cash last year, and the US might be the next.Self-driving Cars
Unlike a human driver, a self-driving car won’t be influenced by a phone call, the radio or something outside the window. Sensors (探测器) and cameras on the car would allow it to follow the rules of the road strictly and keep a safe space from other cars. This would greatly make the number of road accidents smaller. You can even take a short rest while the car drives itself. In the future, driverless cars would be widely accepted.
21．Bionic eyes send information to the ________.
A．mind B．camera C．computer D．heart
22．Which of the following payments is NOT mentioned in this passage
A．Cash. B．WeChat Pay. C．Alipay. D．Credit card.
23．From the report, we can learn some information about ________.
A．industry and farming B．traffic and journey
C．science and technology D．culture and art
24．Which of the following is TRUE according to the passage
A．Bionic eyes only appear in the science fiction films.
B．The blind wearing bionic eyes may see clearly in the future.
C．Self-driving cars will be influenced by something outside.
D．There will be no accidents at all if self-driving cars are used.
25．What can we infer from the passage
A．There would be a number of self-driving cars on the road.
B．Robots would control the world.
C．The blind could use glasses to see things around.
D．We would live a hard life with digital money.
B
Alfredo Moser is a Brazilian worker who is skilled at repairing machines. His wife says her husband has always been handy (手巧的) at home and made tables and chairs. Alfredo has invented a way of lighting his house during the day without electricity.
He has been using plastic bottles filled up with water and a little bleach (漂白剂) to provide dark rooms with light for many years. And the idea has now spread across the world. It is predicted that his lighting system, which works using refraction (折射) of sunlight, will be fitted in over a million homes by the end of this year.
Alfredo used normal plastic drinks bottles that are often thrown away. The secret of the liquid in the bottles is the bleach added to water, which stops it turning green in the sunlight. Mr. Moser drills a hole in a roof tile (在屋瓦上钻洞) and then pushes the bottle in from below, keeping the bottle in place with polyester resin (聚酯树脂). Depending on the strength of sunlight, the light fills his home, and the bottles are just like electric bulbs of between 40 and 60 watts (瓦特).
Alfredo came up with the idea for his “Moser light” during one of the blackouts in Brazil in 2002. He said only factories had power in his home city, in southern Brazil during the energy shortage.
The local supermarket and his neighbors, houses are utilizing Moser lights. He earned a few dollars, but his invention has not made him a rich man. Now a great number of people admire what he is doing!

B．Alfredo couldn’t do any housework.
C．Alfredo was clever with his hands.
D．Alfredo was a helpful man to save our world.
27．Why does Alfredo put a little bleach into the bottle
A．Because the bottle can give more light.
B．Because the bleach can keep the bottle in a roof tile.
C．Because the bleach can protect water from turning green.
D．Because the bleach can reflect the sunlight.
28．Which of the following is TRUE according to the passage
A．People can use Moser’s lights only at night.
B．Moser’s light gives too poor light.
C．Moser’s bottles use electricity to light the room.
D．Moser’s bottle light is a green idea.
29．What does the underlined word “utilizing” in the passage probably mean
A．Selling. B．Using. C．Taking. D．Locking.
30．What can we learn from the passage
A．Alfredo’s lights will be more and more popular.
B．Nobody will buy Moser lights in the future.
C．Alfredo won’t repair machines any more.
D．Alfredo’s invention will bring him a lot of money.
C
A．Sweet Day is useful for you to make sure your breath smells nice or not. Sweet Day covers your nose and your mouth, so it is easy to smell the air that comes out of your mouth.

C． Baidu Chopsticks Search. The new chopsticks, called Baidu Chopsticks Search, can test all kinds of information on food freshness, acidity（酸碱度）and nutrients（营养）. They allow people to take food safety into their own hands through an app on smart phones.
D．“Red Star” Cooker. The cooker is also much “friendlier” than other cookers because it produces less smoke and the user may have less breathing illness from harmful smoke.
E. Ray Glasses.These special glasses show the time above your right eye and the temperature above your left eye. It is surely easier than wearing a watch, and you never have to guess the temperature.
F.Sunshine Watch. It can not only tell you the right time and the temperature. It also has a set of technology that can collect a lot of health information. It can even tell you if you sleep well.
Match the information according to what you read.

The bicycle is one of the simplest but 36 inventions in the world. What is the most surprising is that it was not 37 earlier, although the great inventor Leonardo da Vinci had 38 pictures for bicycles, flying machines and some other things. Those things were not produced 39 long after he died.
A person riding a bicycle uses very little energy to make the bicycle 40 , and there is no pollution at all when you are riding. Even so, in most developed 41 , most people don’t go to work by bicycle. It is not because bicycles are expensive or people feel 42 if they ride to work. It’s because the number of cars on the roads becomes larger. It certainly becomes more 43 to ride a bicycle. As a result, more people put their bicycles away and go to work 44 their cars.
And in this way, the situation is made more serious. Perhaps the best way to make riding safer and more popular is to 45 roads only for bicycles.

Tea bag drinking is most Westerners' favorite way of drinking tea. Do you know how it came about？ The tea bag was invented in 1908 by Thomas Sullivan， an American tea seller. He was sending out free tea in silk bags for people to try. People put the bags together with the tea leaves into the cup and added hot water. The tea tasted good， and people thought it was easy to clean the cup. So they were unhappy when Sullivan sent them loose (零散的) tea again. Sullivan realized that he had a hot new thing in his hands， and he built a machine to pack the bags. As tea bags became popular， they were changed from silk to gauze(纱) and later paper. In 1952， Lipton Tea made the tea bag even more popular with its invention of the four sided tea bag. Tea bags were soon a hit in the UK， and today 85% of the tea in the UK is packed in paper bags. However，many people still prefer loose leaf tea. This is because some tea companies put tea that is not very good in their tea bags.

Dear Judges，
I'd like to introduce my new invention to you. 　
It's a special pen invented in 2023. It's made of steel. It's a little longer than a normal pen. There are three buttons on the pen. I think it's very useful and convenient. When you press the red button，it is used as a pencil. When you press the blue one， it is used as a pen. If you want to use an eraser，you can press the white button. What's more, it will make a sound if you sit in a wrong way.
That's all. Thanks for listening.
