26、 Telling a yellow taxi and a binoculars (双筒望远镜)apart is so easy that most people could do it without a second thought. However, it is not so for an artificial intelligence: if you turn the taxi upside down, it sees Binoculars.
This is just one of dozens of examples that show AI is a lot worse at identifying(识别) objects by sight than many people realize. The examples, collected by Anh Nguyen at Auburn University in Alabama, raise concerns about the real-world ability of AI image recognition systems.
Nguyen and his colleagues took images of common objects from the Internet and rotated (旋转) and changed the position of the objects in the pictures. They found this was enough to confuse several AI systems, including Google’s. In one case, a school bus that was correctly identified in the original image was misidentified as a lunch box when upside down in the road. It shows these systems aren’t as intelligent as many people think they are.
Nguyen worries what could happen in real-world situations. For example, it makes sense for a driverless car with AI system to avoid an object it can’t recognize. But if the car stop unexpectedly because it thinks a Coke can is a fire fighting truck, this could be as dangerous as thinking a fire fighting truck is a Coke can. This is one reason why driverless cars will need several sensors (传感器) to provide more information, says Nguyen.
His team has been discovering these problems for the past few years, but nobody knows how to fix them. The biggest problem to progress is that when an AI looks at an image, it can’t extract (提炼) rules that would help it identify a similar one next time – such as the rule that horses have four legs. “To reach a human level of reasoning, we need a way to extract rules from images,” says Nguyen.
【1】In paragraph 1, the example of a taxi is used to .
A.raise people’s concerns about the safety of AI system.
B.prove that human beings are much smarter than AI systems.
C.introduce the topic concerning AI’s image recognition ability.
D.show a taxi can have different forms when seen from different views.
【2】We can learn from the last paragraph that .
A.AI can’t tell a horse and a car apart because they both have four legs.
B.AI can’t reason like human, which is the biggest challenge.
C.AI doesn’t have the ability to tell things apart that look similar.
D.AI can’t identify images from earlier experiences.
【3】What is the best title for this passage?
A.Problems remain to be solved.
B.AI is no cleverer than human beings.
C.AI can’t see things from another view.
D.Driverless cars need to be improved.
27、There are nearly 2,800 working satellites in space, which we depend on for technology we use every day, such as video calls, online maps, satellite TV, and weather tracking. Scientists use them to study space and learn more about our planet.
But there are many other satellites in orbit (轨道) that are no longer working. They're among the objects cluttering (使杂乱) up space. Some of these eventually fall back toward Earth, either landing or burning up in the atmosphere. But much of this space junk (垃圾) circles Earth for years. Space junk is a problem. Debris (残骸) floating around Earth puts technology and future space tasks at risk. Experts are working on ways to solve it.
Orbital debris, a type of space junk, is any human-made object that has slopped working but continues to float around the Earth. This includes satellites that are no longer used and pieces of spacecraft, such as rocket stages. It has been a large problem since the 1960s.
Space junk also includes broken pieces of objects. These occur when satellites hit against things. They also result from an object crashing into an old rocket stage that still contains fuel, causing an explosion (爆炸) . There have been more than 250 space explosions since the 1960s. These tiny broken pieces can damage working satellites, which can affect research in space.
Companies all over the world are working to clean up the area surrounding our planet. A company based in Japan will test the method of using magnets (磁石) to collect space debris. Another mission is led by a company based in Switzerland. It plans to carry out a debris-removal spacecraft in 2025. The craft will get hold of a piece of an old rocket, slow it down, and move it back to Earth. Eventually, the debris will burn out like a shooting star.
Governments are trying to help too. Some are updating their country's space guidelines to limit the amount of debris created. Space is so large that the problem won't be solved by a single organization or a single country. We have to work on this together.
【1】What is the biggest harm that space junk does to human beings?
A．It will fall back toward the Earth.
B．It circles the Earth for years.
C．It puts other space objects in danger.
D．It will burn up in the atmosphere.
【2】How will the Swiss company clean up the Earth orbit?
A．By making the orbital debris fall back to Earth.
B．By putting the pieces all together.
C．By collecting space junk with magnets.
D．By sending space junk into deep space.
【3】What does the author suggest on cleaning up space junk?
A．Strict laws.
B．Global efforts.
C．Stopping in space exploration.
D．Setting up professional organizations.
【4】What does the text mainly talk about?
A．Earth and its satellites.
B．The problem of space junk.

D．The various uses of man-made satellites.
28、We are what we eat. That is an old expression, but one worth knowing. A recent look at diets around the world shows that people who eat healthy food—and not too much of it—live longer. But which areas of the world have the best diets？Researchers found that foods in some of the healthiest diets—Mediterranean, New Nordic, Japanese and French—may be very different, but they are all heavy on local, seasonal and limit processed foods, which are high in vegetables and seafood and low in red meat.
Mediterranean diet contains lots of fruits, vegetables, whole grains, nuts and olive oil. The diet has proper amounts of fish and poultry (禽肉). Red meat and foods high in sugar and salt are not big parts of this diet.
New Nordic diet has whole grains like oats and rye, vegetables such as carrots, broccoli and eggs, seafood, fruits, oil, lowfat milk and cheese. Very sugary desserts are not common in this diet.
Japanese people are some of the longestliving people on the planet, with women up to 87 years old and men up to 80. The Japanese diet is the reason for such lengths of life. The diet has many foods that are low in calories and high in nutrients. Japanese people eat a lot of seaweed, tofu, rice, vegetables and fish. The tradition there is to stop eating when your stomach feels 80 percent full.
However, French people eat fatty foods but do not get fat. And they live a long time. This phenomenon is called the "French Paradox". The reason why the French eat fatty foods without getting fat may be simple. They eat less. Serving sizes in French restaurants and in products sold in stores are smaller than those in most countries. And generally speaking, most French people do not snack. This means they do not eat food between meals.
【1】What do we know about the healthiest diets around the world?
A．They contain abundant calories.
B．They tend to be expensive.
C．They share certain similarities.
D．They reflect popular tastes.
【2】What is considered as a harmful eating habit in Japanese tradition?
A．Going low in calories.
B．Eating to the fullest.
C．Having much seafood.
D．Picking many foods.
【3】How does the author develop the central idea in the last 4 Paragraphs?
A．By building connections.
B．By exploring reasons.
C．By listing out examples.
D．By analyzing figures.
【4】Which can be the most suitable title for the text?
A．What is the healthiest diet on earth?
B．How does the old expression serve?
C．Why is a healthy diet so important?
D．Where can we plant ourselves well?
29、 The word addiction (上瘾) usually makes you think of alcohol or drugs. 【1】. Some people are compulsive (难以自制的) shoppers. Others find it impossible to pull themselves away from their work. Still others spend countless hours watching TV or playing computer games.
【2】. Many people enjoy going to markets or stores more and more every day, but it’s more than a common hobby for some of them. They have turned into shopaholics. They are people who simply enjoy shopping and walking around spending money without being able to stop doing it. They are so interested in shopping that they usually buy things they don’t need. Even though they don’t have enough money, they buy everything they want.
The question is: why do they have this addiction? There isn’t a specific answer. Some people go shopping when they are sad, worried, upset or lonely and they want to feel better. Shopaholics say that they feel more important and better after they buy something. 【3】.
Shopaholism seems to be a harmless addiction, but it can bring out problems. Some of them can be psychological. If this is the case, people addicted to shopping should go to a support group to help them break this habit. However, the process, like for most addictions, is long, and they suffer a lot. 【4】. They just think about satisfying their feelings, so they spend money they don’t have. 【5】.
A.Once you are addicted to alcohol or drugs, it is difficult to get rid of.
B.Over the years, shopping has become a very common activity.
C.They use this activity as a way to forget their problems.
D.However, in modern-day society we are seeing some new kinds of addictions.
E.People addicted to computer games consider the games as great ways to amuse themselves.
F.They get deep in debt, and can even go bankrupt (破产) and get sent to prison.
G.It can also cause financial problems.
