After you finish your fries, eat the package. When you add your noodles to boiling water, throw the bag into the pot, too. If these instructions sound confusing to you, it’s only because you haven’t yet heard of Notpla, a London-based start-up company that is designing a seaweed-based replacement for single-use plastic packaging.

The approach feels especially great as the world is coming to terms with the effects of decades of plastic production. According to the UN, 330 million tons of plastic waste is produced globally each year, and out of the 9 billion tons of plastic produced since the early 1950s, about 60% has been buried or thrown away as rubbish. Microplastics — tiny pieces that are often the result of larger plastics breaking down — pollute the ocean, the air and our bodies.

“It’s getting more and more clear how big the plastic problem is,” Notpla design director Karlijn Sibbel said. “Producers are ‘using materials that last for thousands of years for products that are only in use for a few minutes’. We firstly looked to seaweed as the solution to the world’s plastic problem because there is plenty of it, it crows quickly, it doesn’t compete with land crops, and it absorbs carbon from the air,” added Sibbel.

“The exciting thing is that the new product named Ooho is a film that can replace most of the flexible packaging that you see around,” Sibbel said. The potential contents could include coffee grounds, toilet paper or the nails used for making furniture. For foods, such as noodles, they have even experimented with adding more taste to the packaging, so that dissolving the bag could add seasoning to the pot.

Last year, Notpla tested 30,000 takeaway boxes in partnership with the online food ordering service Just Eat. The two companies handed out the takeaway boxes at different UK restaurants and plans are being made to offer the boxes around Europe in 2022. As they expand, Notpla’s team hopes seaweed could replace single-use plastic in the supply chain more broadly, but with a large quantity of plastics used around the world, she understands how difficult such a task is, Sibbel said.

1. How does the author introduce the topic of the passage?
A.By comparing facts.B.By giving examples.
C.By raising questions.D.By analyzing data.
2. How much plastic has become rubbish since the early 1950s?
A.About 198 million tons.B.About 5.4 billion tons.
C.About 330 million tons.D.About 9 billion tons.
3. What does paragraph 4 mainly talk about?
A.The potential use of the new product.B.The new application of plastic bags.
C.The motivation for the new study.D.The next goal of the new research.
4. What does Sibbel think of their task to replace single-use plastic in the supply chain?
A.It is helpless.B.It is impractical.
C.It is challenging.D.It is a short-term project.

【推荐1】You’re on the third lap around the car park, there are no open spaces, and you’re already 15 minutes late for your appointment. Right now you’re wishing you could jump out of the car and let it go find its own spot.

Now there’s an app for that. Virtual Valet lets your iPhone tell your car to park without you in it. “You pull up to the roadside, push a button on your smartphone and the car takes care of everything else,” says Aeron Steinfeld, the lead researcher for the project at Carnegie Mellon University in Pittsburgh, Pennsylvania.

To find its own spot, the system uses a sensor suite similar to those found in many luxury cars. This includes a motion sensor that scans for moving cars and pedestrians, and a forward-facing laser rangefinder normally found in adaptive cruise control to determine the distance of objects in front of the car. Information from these sensors is then fed to an onboard computer to plan the vehicle’s course. The user can watch the whole process from his or her phone.

Better still, it will be affordable. The team has spent the last year moving from high-end imaging and processing equipment to less expensive components. In experiments, the vehicle was able to navigate through a crowded parking structure, find an empty spot, and park all on its own. And the greatest appeal of the Virtual Valet Parking App is that it requires no change to existing parking facilities or infrastructure.

For the moment, the only car equipped for control by Virtual Valet is Carnegie Mellon’s modified (改进的) Jeep Wrangler, which the researchers have named NavLab11. But Steinfeld hopes that major car manufacturers will adopt the technology.

It might be more than technology that holds up the show, however. Self-driving cars have been licensed in only three US states — California, Nevada and Florida — and it’s unclear how this app would agree with self-driving laws. Until these questions are settled, your insurance provider might be unwilling to cover a ding from a parking incident.

1. It can be learned from the second paragraph that     .
A.parking lots are too crowded
B.parking spaces are too limited
C.your car can park automatically via a smartphone app
D.you can leave your car alone if you can’t find a parking spot
2. What’s the main idea of Paragraph 3?
A.How to determine the distance of objects.
B.How the Virtual Valet Parking App works.
C.How to use the system.
D.How to analyze the information about the vehicle’s course.
3. What is the biggest advantage of the system according to the text?
A.It is very cheap.
B.It can help your car park wherever you want.
C.It is very convenient to use.
D.It can adapt to the present parking facilities.
4. We can infer from the text that     .
A.no car manufacturers show interest in the technology
B.there will be some difficulties in promoting the technology
C.the technology is now widely used in the US
D.the technology conflicts with self-driving laws in the US

文章大意:这是一篇说明文。文章介绍了现代机器人发展及存在的问题。

【推荐2】Li Bai holds a wine cup in his hand, while Du Fu sits in front of a desk, writing poems on the paper in front of him. It’s not that we have traveled to the past. Modern technology has brought ancient poets “back to life” .

The two great poets, along with other humanoid robots were presented at the World Robot Conference 2023 in late August in Beijing. They looked similar to real human beings.

“The skin is made of medical-grade bionic silicone (仿生硅胶) which is why the skin looks soft and veins can be seen through it,” CGTN explained in a video about Liaoning-based producer EXROBOTS. Goosebumps (鸡皮疙瘩) and palm lines can also be seen on the arms and hands.

Researchers are also trying hard to create other features of humans on robots. A US robotics company Apptronik brought out its humanoid robot called Apollo on Aug 23. Apollo has around 30 muscles. However, humans have around 300 muscles in our bodies. For now, engineers can only simplify the muscles, allowing them to do basic movements like holding objects and walking.

The robot also contains cameras, helping it map out a 360-degree view of its environment. It also has sensors (传感器) in its head to help keep balance when walking on uncertain surfaces.

Nowadays, bionic human-like robots mostly work with humans, as tour guides or by helping visitors at front desks. There are also robots that share the work of nurses, such as handing out medicine. This could be because people are comfortable living and working with machines that look or act like them. “They can strike a chord (引起共鸣) with people,” a US robotics scientist Marc Raibert told New Yorker.

As more humanoid robots come out, safety will be the key, according to the Robot Reportwebsite. When a 70- kilogram robot breaks down and falls, humans nearby may be hurt.

1. What does brought ancient poets “back to life” mean in Paragraph 1?
A.The robots can create better poems than poets.
B.Technology can make ancient poets back to life.
C.Visitors can experience real ancient life with robots.
D.The robots looked and acted like real ancient poets.
2. What does the skin of robots made by EXROBOTS show?
A.How human-like their robots are.
B.How soft the robots skin is.
C. How the robots’ skin should be made.
D.How different they are from other robots.
3. What can Apollo do with built-in sensors?
A.Wave at humans.B.Walk stably.C.Know human faces.D.See better.
4. What do people worry about with human-like robots?
A.People may be at war with the robots.B.Human-like robots look scary.
C.The robots weight may cause problems. D.The robots may get out of control.

【推荐3】Scientists have designed a new machine—a robot which looks exactly like the famous scientist Albert Einstein. It can recognize and respond to human emotions (情感). The robot is made of special material that allows it to change facial expressions. The material that makes up the robot’s face is so detailed that it looks like real human skin.

The robot’s designers chose Einstein, the Nobel Prize winner, because he was one of the greatest scientists of all time. They also chose Einstein because his face is very well known and he appear ‘loveable’.

Dr. Hanson, who designed the robot, explained that it was important to develop machines that know what human beings are feeling.

The robot uses computer software that helps it to understand hundreds of human expressions such as sadness, anger, fear and happiness. It can also recognize a person’s age, and whether they are male or female. Mr. Movellan, who designed the software, said that in the future the robot could be in museums to help people from different cultures to understand one another.

1. What do we know about the robot?
A.It can recognize and respond to human emotions.
B.It can develop new machines for children.
C.Its color can be changed easily.
D.Its material is very common.
2. Who was one of the designers of the robot?
A.Albert Einstein.B.Dr. Hanson.C.Mr. Nobel.D.A tour manager.
3. What might be the best title for the text?
A.Robot copy of Albert EinsteinB.New type of museum
C.How to design a museumD.How to express feelings
