Shopping centers，stadiums and universities may soon have a new tool to help fight crime.
ACaliforniacompany called Knightscope says its robots can predict and prevent crime. Knightscope says the goal is to reduce crime by half in areas the robots guard.
William Santana Li is the chief executive officer of Knightscope. He says，"These robot security guards will change the world. Our planet has more than seven billion people on it. It's going to quickly get to nine billion people. The security equipmentthat we have globally is just not going to develop that fast. The company's Autonomous Data Machines can become the eyes and ears of law enforcement（执法）."
"You want them to be machines plus humans. Let. the machines do the heavy and sometimes dangerous work and let the humans do the strategic decision-making work，so it's always working all together."
The machines do not carry weapons but they have day and night video cameras which are able to turn 360 degrees and can also sense chemical and biological weapons.
Some people may become concerned about their privacy, especially in connection with the video recordings. Some people may worry that such recordings will appear on the Internet. Eugene Volokh, a law professor at the UCLA School of Law, says the machines have to be used in the right way and it will be interesting to see how state laws deal with this kind of video.
William Santana Li says there is a long waiting list for the robots in theUS. Workers in the company are working overtime to meet the demands of the market. At least 25 other countries are also interested in these robot security guards.
1. What can this new tool do for humans?
A. Make strategic decisions.
B. Keep watching day and night.
C. Carry heavy weapons.
D. Stop crime autonomously.
2. Why are some people worried about the new robots?

Babies who frequently communicate with their caregivers using eye contact and vocalisations(发声)at the age of one are more likely to develop greater languages skills by the time they reachtwo,according to new research.
In the study, researchers looked at 11-and 12-month-od babies' vocalisations. gestures and gaze behaviours ,and at how their caregivers responded to them.To measure he interactions ,the researchers videoed infants(婴儿)and caregiver at home,and asked them to play as usual.They took those recordings back to the university
The scientists then used statistical models to find that the best predictor of vocabulary at 24 months was when infants were seen to use vocalsatioms while looking at their caregiver's face when they were about a year old.The benefits were even greater when these interactions were followed by responses from the caregiver.
The statistics showed that at 19 months,children had an average of about 100 words.Those who exhibited the beneficial interactive behaviour earlier in life were seen to have an average of about 30 extra words.
"The message of this paper is thatitis the result of a joint effort; noticing what your child is attending to and talking to them about it will support their language development." said McGillion, a co-author of the work.
"The joy of this message is that that can happen in any context... across any part of your day.It's not something that requires special equipment or even lots of time.I can happen when you're doing the laundry,for example—when you're taking out the socks, you can talk about socks...in the park, in the car, at mealtimes,at bathtimes.This finding can be used in any context,"added McGillion.
"This is a developmental snapshot in the first year of life, but children are constantly growing and changing and so are their behaviours. It would be interesting to look at these sorts of behaviours again as children progress through the second year of life to see what's happening there,"said Donnellan,the lead author on the study.
4. How did the researchers get the findings?
A. By interacting with babies.
B. By asking babies to vocalize.
C. By analyzing relevant recordings.
D. By referring to the previous statistics.
5. What does he underlined word "it"in Paragraph 5 mean?
A. Infants' eye contact.
B. Infants' larger vocabulary.
C. The response from caregivers.
D. The best predictor of vocabulary.
6. What did McGilion say about infants' interactive behaviour?
A. I's easy to perform.
B. It's complex to understand.
C. It's difficult to copy.
D. It's interesting to video.
7. What might further studies be on?
A. Children's academic progress.
B. Children's growing environment.
C. Children's potential physical development.
D. Children's behaviours across more age ranges.
C
Scientists at the Massachusetts Institute of Technology (麻省理工学院) have turned spider webs into music——creating an strange soundtrack that could help them better understand how the spiders output their complex creations and even how they communicate.
The MIT team worked with Berlin-based artist Tomas Saraceno to take 2D (two-dimensional) laser (激光) scans of a spider web, which were linked together and made into a mathematical model that could recreate the web in 3Din VR (virtual reality). They also worked with MIT’s music department to create the virtual instrument.
“Even though the web looks really random (随机)，there actually are a lot of inside structures and you can visualize (可视化) them and you can look at them, but it’s really hard to grasp for the human imagination or human brain to understand all these structural details,” said MIT engineering professor Markus Buehler, who
presented the work on Monday at a virtual meeting of the American Chemical Society.
Listening to the music while moving through the VR spider web lets you see and hear these structural changes and gives a better idea of how spiders see the world, he told CNN. “Spiders use vibrations (振动) as a way to locate themselves, to communicate with other spiders and so the idea of thinking really like a spider would experience the world was something that was very important to us as spider material scientists,” Buehler said.
Spiders are able to build their webs without shelves or supports, so having a better idea of how they work could lead to the development of advanced new 3D printing techniques. “The reason why I did that is I wanted to be able to get information really from the spider world, which is very weird and mysterious,” Buehler explained. In addition to the scientific value, Buehler said the webs are musically interesting and that you can hear the sounds the spider creates during construction. “It’s unusual and eerie and scary, but finally beautiful.” he described.
8. What have MIT scientists done according to the passage?
A. They have translated spider webs into sounds.
B. They have made a mathematical model to produce webs.
C. They have created a soundtrack to catch spiders.
D. They have known how spiders communicate.
9. What can we know about spider webs from paragraph 3?
A. Their structures are beautiful and clear.
B. Professor Markus Buehler knows them well.
C. The American Chemical Society presents the result.
D. They are complex for people to figure it out.
10. In which field will the study be helpful?
A. virtual reality
B. printing
C. painting
D. film-making
11. What is the main idea of the passage?
A. It tells us that the music created by spiders is scary.
B. It shows how the researchers carry out the experiment.
C. It presents a new and creative way to study spiders.
D. It explains why scientists did the experiment.
D
The annual 3-to-4-millimeter rise in sea levels is expected to impact many coastal communities in the coming
decades. However, few are as defenceless as the Republic of theMaldives, a collection of more than a thousand picturesque islands in theIndian Ocean. NASA researchers believe that parts of what is “arguably the lowest-lying country in the world” will become uninhabitable by 2050, due to wave-driven flooding and limited freshwater. To fight the unavoidable, the government recently revealed plans for the world's first 'true' floating island city.
The aptly-named Maldives Floating City (MFC) is the brainchild of Dutch Docklands, a global leader in floating infrastructure (基建). According to the March 13, 2021, announcement, the new city will be constructed on a 200-hectare lagoon (环礁湖) located just 10 minutes by boat from the Maldivian capital, Male. It will initially consist of a thousand waterfront residences, arranged in a series of honeycomb-like maze rows. The developers plan to add hotels, restaurants, shops, and even a school and a hospital in the near future. The floating structures. will be attached to the surrounding islands, which will form a base and provide protection from high tides.
Maldive officials aim to make MFC as self-sufficient as possible. Freshwater storage will provide drinking water for residents, while floating solar blankets and agriculture fields will take care of their energy and food needs.
“ThisMaldivesFloatingCitydoes not require any land rehabilitation, therefore has a minimal impact on the coral reefs,” explains Mohamed Nasheed, Speaker of Parliament. “What's more, giant, new reefs will be grown to act as water breakers. In theMaldives,we cannot stop the waves, but we can rise with them.”
Construction of the revolutionary city is expected to begin in 2022 and be completed in phases over the next five years. If successful, it will provide a blueprint for other countries facing a similar situation.
12. Why doesMaldivesdecide to build MFC?
A. It is the lowest-lying country.
B. It will be flooded soon.
C. It is running out of fresh water.
D. It will be unsuitable for living.
13. What is Paragraph 2 mainly about?
A. The prospect of MFC.
B. The developers of the plan.
C. The location of the residences.
D. The barriers to the construction.
14. What can we infer from the underlined words?
A. MFC will keep waves away.
B. MFC will make use of waves.
C. MFC will adjust to the waves.
D. MFC will work as water breakers.
15. What's the writing purpose of this passage?
A. To introduce a construction program.
B. To appeal to people to protect nature.
C. To seek international help forMaldives.
D. To report the achievement of a city plan,
