1 . The SNAG stands for stereotyped nature-inspired aerial grasper and it’s a 3D-printed bird robot with claws. It can fly, stay on various surfaces catch and carry objects, just like the mighty falcon（隼）that was used as the source of inspiration in its development.

Each leg of the SNAG has two motors, one for helping it move back and forth, and the other one for grasping. Twenty printing attempts were necessary for the robot to finally reach its current structure, but it was worth it. Now, according to researchers, the flying machine has an impressively strong and high-speed clutch（离合器），being able to land and wrap its claws around a branch in about 20 milliseconds. SNAG has ankles lock, and there’s an accelerometer （加速计）on its right foot that reports that it’s landed while triggering（触发）a balancing process to stabilize it.

Scientists have already conducted several tests with the robot in rural areas and on different surfaces. In all the situations, the SNAG was able to catch objects thrown by hand, such as bean bags, a tennis ball, and more.

As for the applications of the bird-like robot, the SNAG can get attached to drones（无人机）and be used for search and rescue missions, wildfire monitoring, to offer just a few examples. Another great application is environmental research, with the SNAG also featuring a temperature and humidity（湿度）sensor. By using a robot that can act like a bird, you can unlock new ways of studying the environment, as explained by William Roderick, mechanical engineer and one of the researchers involved in the project. Now scientists are moving on to improving the robot’s situational awareness and flight control.

This isn’t the first time that nature has inspired groundbreaking technologies. We also wrote a piece recently about the F-SAM micro drone, which was inspired by the flight of samara（翼果）seeds, also known as “twisters” which have a special way of spinning down to the ground.

2 . Facial recognition software has found an unlikely new application: scanning the faces of thousands of British children in school canteens.

Nine schools in North Ayrshire will today start taking lunch payments by scanning the faces of pupils, claiming that the new system speeds up queues and is more secure than the card payments and fingerprint scanners they used previously. “It’s the fastest way of recognising someone at the till,” said David Swanston, the managing director of CRB Cunninghams, the company that installed the systems. “In a secondary school you have around a 25-minute period to serve potentially 1,000 pupils. So we need fast productivity at the point of sale.” He said the average transaction time was cut to five seconds per pupil.

However, privacy campaigners say there is little need to spread out facial recognition technology, which has been criticized for often operating without gaining approvals from the owners. Swanston argued that CRB Cunningham’s system, which uses cameras to check against coded face-print modes stored on servers at the schools, was different from live facial recognition systems that scan through crowds to identify faces. Live facial recognition has previously caused debate after being used by schools for security or to monitor attendance.

North Ayrshire committee said that 97 percent of children or their parents had given agreement for the new system. “Pupils often forget their PINs and unfortunately some have also been the victim of PIN cheating, so they are supportive of the planned developments and appreciate the benefits to them,” the council said.

But some parents said they were unsure whether their children had been given enough information to make their decision, and suggested that peer pressure had also played a role.

1. What can we infer from Swanston’s word?

A．He speaks highly of the system.

B．The software is intended to promote the sales.

C．The technology has previously caused debate.

D．The system will be helpful when the students forget their PINs.

3 . 阅读下面材料，根据其内容和所给段落开头语续写两段，使之构成一篇完整的短文。

A New Addition to the Family

For the initial ten years of his life, Victor was the prince of the household. As he was an only child, his parents petted him and showered all their love and attention on him. Whatever toys his parents bought, they were always meant for him. Whatever food was in the refrigerator, there was no one to compete with him to polish it off first. Victor could leave his toys or books around the house with complete ease of mind, knowing that there was no one who would get their hands on his belongings and cause any damage.

However, all that was to change overnight when Victor’s parents brought back his new baby sister, Lina, from the hospital. With her rosy cheeks, wide open eyes and angelic smile, Lina caught the hearts of her parents, grandparents and relatives. Everyone focused their attention on the cute bunch of joy. Whenever she cried, her mother or father would rush to her bed. She simply cried because she wanted to be carried. There was little time left for Victor.

Now that Victor’s mother had his baby sister to take care of, she expected Victor himself to do most of the chores he can do. Victor was asked to clean his own room, iron his own school uniform and clean his own shoes. Before Lina’s arrival, he had never lifted a finger to help out with these tasks. The whole family also went out less because it was unhealthy to expose Lina to the bacteria(细菌) being in the outside world too often.

Victor felt neglected by his parents. He felt that they loved Lina more than him. As a result, he tried to attract his parents’ attention by becoming resistant. One evening, Victor’s parents were called up by his teacher because Victor had got into a fight at school. His teacher had noticed Victor’s behaviour and work attitude changing downwards in the past two months. Before that, he had been a model student.

4 . 阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。

Recently, Chinese people from all walks of life    1    (discover)their daily lives are filled with an academic term; involution(内卷). In agricultural economics, involution originally means that    2    (add) work is put into agricultural production for higher output,    3    yet doesn’t increase proportionally(成比例地).

Our society is becoming increasingly competitive when population outgrows resources. Accordingly,    4    we used to achieve easily requires more efforts now. The level of competition we have in our society is often compared to millions of troops    5    (cross) a single wooden bridge. The    6    (major) of us are trying hard to get ahead of the troops.

Netizens now use involution to describe their current conditions, especially in the study of children. Parents feel stressed    7    (provide) their children with the best, and children must keep    8    in the race. Though great efforts have been made, they find it much    9    (hard) to go to the schools that they have been looking forward to.

Too much pressure is bound to do harm to children physically and mentally. Parents should cool down firstly and relieve their own anxiety, taking    10    (measure) to rid their children of heavy burden from involution.

5 . New England holds some special museums. They are devoted largely or entirely to the work of just one person. And they are the artists’ birthplaces or onetime homes. Here are four examples of such museums.

Cyrus E. Dallin Art Museum

The name Cyrus E. Dallin (1861-1944) might not be familiar, but several of the artist’s sculptures (雕塑) are, especially those related to Native Americans. A good example is his “Appeal to the Great Spirit” standing in front of the Museum of Fine Arts. Born in Utah, he lived in Arlington for the final four decades of his life. The museum is in the Jefferson Cutter House, an 1830 Greek styled building.

Norman Rockwell Museum

Rockwell (1894-1978) was America’s well-known artist. The museum, founded in 1969, moved into its present location, Robert A.M. Stern-designed building in 1993. Its 998 paintings and drawings are the largest single collection of Rockwell's artworks.

9 . Which is better for Earth: an electric or gas-powered vehicle? The answer to this question might seem blindingly obvious. Of course electric cars must be better for the environment, because they don’t give off greenhouse gases as people drive. However, electric vehicles (EVs) aren’t perfect, and they come with their own set of polluting problems. Their batteries require a large amount of energy to produce.

Battery production is just one part of an electric car’s life span. A study looked at the entire life cycle of an EV’s emissions(排放)，from mining the metals for the batteries to producing the electricity needed to power them, and then compared this with the average emissions of a gas-powered vehicle. The team found that when EVs are charged with coal-powered electricity, they’re actually worse for the environment than gas-powered cars.

“Only when connected to the clean energy do EVs have an advantage over the gas-powered cars on a greenhouse gas basis,” said Colin Sheppard, an expert in energy and transportation systems. That’s why more and more countries are decreasing the power supply from coal. In China, the national grid is improving with more efforts in renewable energy. For example, it has twice as much wind energy capacity as the U.S. and it builds more solar panels per year than any other countries.

Sheppard has modelled a future in which all cars are electric. “We want to understand what it might be like if all passenger vehicles were electrified.” The model suggests that if all vehicles in the U.S. were electric, greenhouse-gas emissions would be 46% less every year. This reduction could be increased even further if those vehicles were using a technique known as “smart charging” in which cars are recharged at chosen times (often at night) to reduce the cost of electricity.

In short, it’s far easier to argue for buying an EV than a gas-powered vehicle. But what about the cost? Aren’t electric vehicles too expensive for most people?

1. In which case do EVs get more heavy-polluted than gas-powered cars?

A．Being powered only by batteries.

B．Using coal-powered electricity.

C．Starting to give off greenhouse gases.

D．Replacing gas-powered vehicles entirely.

2. How does Sheppard’s model show the reduction of greenhouse-gas emissions?

A．With a discussion.	B．With an examination.
C．With a comparison.	D．With a questionnaire.

3. What can be inferred from the text?

A．China is making advances in renewable energy.

B．Compared with gas-powered cars, EVs are at an advantage.

C．There is still room for the development of EVs.

D．It’s not a challenge to choose between EVs and gas-powered cars.

4. What might the paragraph following the passage be about?

A．Inventing green gas-powered vehicles.

B．Developing environment-friendly grids.

C．Getting rid of fossil energy like coal and oil.

D．Making electric vehicles more affordable.
