21、Have you ever lost something in a hard-to-reach space, like behind a couch or a cupboard? Wouldn’t it be nice to just be able to squeeze in and out? New innovations in the field of robotics will soon be able to make this mice idea into a reality.
In a study published on Jan 25 in the science journal Matter, engineers from The Chinese University of Hong Kong and Carnegie Mellon University in the US have developed small robots that can quickly change back and forth from liquid to solid states.
According to the website Mashable. the scientists were inspired by sea cucumbers. They are able to change the stiffness (僵硬度) of their body or reduce the potential for physical damage. The robots in the study were made from gallium (镓), a soft meta with a low melting point of 30 C. The scientists then used changes in the magnetic field to control the magnetic particles inside the gallium material to provide heat. This heat then allowed the robots to change between solid and liquid states as well as to move around.
As the website Tech Xplore pointed out, other similar materials require external heat sources such as heat guns and electrical currents to induce a change of states; but now, the robots can use a heat source inside itself to change states independently. During the robots” experimental trials. the scientists conducted a number of tests. These tests included having the robots melt into liquid and re-form to escape a prison-like cage. It can remove a foreign object from and deliver medicinal drugs to a model stomach. The robot is also able to build and repair hard-to-reach circuits. The robots’ ability to switch between states of matter allows for a number of possible uses and advancements in different fields, such as the biomedical and circuit assembly (组装) industries.
Still, in the words of senior author Carmel Majidi at Carnegie Mellon University, for now these are all just “proofs of concept” which show the abilities of these new kind of robots.
【1】Why can the robots switch between solid and liquid?
A．Because they consist of a unique metal and magnetic particles.
B．Because they can reduce the potential for physical damage.
C．Because they are able to change the stiffness of their body.
D．Because they have external heat sources any time any where.
【2】What does the underlined word “induce” in Paragraph 4 probably mean?
A．witness
B．remove
C．cause
D．accept
【3】What will be the function of the robot?
A．To help scientists inspire sea cucumbers.
B．To put a couch into a hard-to-reach space.
C．To get rid of foreign objects from an organ.
D．To assist people in escaping a prison-like cage.
【4】Where is the text probably taken from?
A．A health report
B．A science fiction.
C．A Chemistry textbook.
D．A scientific magazine.
22、Cities are taking steps to support wildlife populations and educate citizens about the importance of the environment. Here are four of the most wildlife-friendly cities in the United States.
Austin, Texas
Austin, the capital of Texas, earns the rank as the top city for wildlife in large part due to its work to help improve declining monarch butterfly populations. Austin sits within the main migration pattern of the monarch, which means that monarch butterflies pass through it twice annually. Austin also leads all US cities with 2,616 certified (经认证的)wildlife habitats.
Atlanta, Georgia
Atlanta secures the second-place ranking thanks to its Climate Action Plan, which aims to expand on the 3,000 acres of parks that the city already manages. Already classified by the US Forest Service as one of the most forested urban centers in the country, Atlanta also calls fbr planting more trees and creating more green spaces based on its climate plan. Six neighborhoods in Atlanta have been designated (指定)as Community Wildlife Habitats. Put together, these areas of vegetation can help reduce the urban heat island effect in the city.
Seattle, Washington
Seattle is home to 489 parks that span 6,441 acres, including 2,500 acres of forested public land. The city’s largest park, Discovery Park, covers 534 acres and serves as an important protected area fbr birds and marine animals. Due to the amount of forested land in Seattle, the researchers use the city to study how urban environments can be designed to support wildlife. The Seattle Urban Project enlists the community to report wildlife sightings, which helps to demonstrate how and where flesh-eating mammals can coexist with humans.
Chula Vista, California
Chula Vista, a city in southern California, ranks high on the list due to its efforts to combat water use issues. The city’s NatureScape Program encourages citizens to replace lawns with gardens of native plants that attract pollinators (传粉昆虫)and conserve water. The city has also formed the CLEAN group, a partnership between the government, businesses and community groups designed to address environmental issues.
【1】What is special about the city Austin, Texas?
A．It manages the largest green spaces.
B．It owns the largest number of parks.
C．It can report the most wildlife sightings.
D．It has got the most certified wildlife habitats in the US.
【2】What do the researchers in Seattle try to find out?
A．How to build more parks in the city.
B．How to make the city wildlife-friendly.
C．How to improve biodiversity in the city.
D．How to make the city more livable fbr humans.
【3】Which of the following contributes to helping more native plants to reproduce?
A．The CLEAN group.
B．The Climate Action Plan.
C．The Seattle Urban Project.
D．The Nature Scape Program.
23、The benefits of outdoor play are fairly well-understood by parents. 【1】. As a mother to three energetic children who spend considerable amounts of time outdoors, I have figured out some good ways to maximize outdoor playtime. I’d like to share some of my advice with readers who might be struggling with this.
【2】. If you start viewing daily outdoor play as being as important as a meal or a good night’s sleep, you’ll start to find more time for it. Think of it as nonnegotiable; no extra things should happen until outdoor playtime has been checked off the list.
Replace organized activities with unorganized ones. Instead of packing your after-school calendar with sports training and interest classess, cancel those for at least several times a week and just tell your kids they can play outside instead.【3】.
Mandate (强制规定) outdoor family time on weekends. My family goes cross-country skiing every single Saturday morning in winter.【4】, even when the temperature drops to -20℃. This time is fiercely protected because of the benefits it has for all of us-exercise, fresh air, satisfaction and family bonding.
Go outdoors with your kids. If you go outside, younger ones in particular will want to be there, too. Make it fun by lighting a campfire in the backyard or setting up a camp stove to make hot chocolate. Or you can have a picnic or work in a garden together.【5】; you can be present without being engaged.
A．We never skip it
B．Start thinking of it as a necessity
C．We adjust the skiing routine accordingly
D．List special activities for outdoor playtime
E．These unexpected arrangements will surely excite your kids
F．You can even just sit and read a book while your kids play nearby
G．However, it’s hard for many parents to fit outdoor playtime into their kids’ days
