1、特色重组练二.阅读理解A(2019广东模考)We have all been there. In a rush to leave the house we grab our phones ahead out of the door, realizing all too late that the battery is dead because we forgot to plug it into the table cloth. Or perhaps we have not. But this could be in future that scientists hope to explore
2、with electronic sheets that charge our mobile phones, laptops and other equipment by harvesting energy from the world around us.In a step in that direction, scientists at Massachusetts Institute of Technology (MIT) have created superthin, bendy materials that absorb wireless Internet and other elect
3、romagnetic waves in the air and turn them into electricity. The lead researcher, Tomas Palacios, said the breakthrough smoothed the way for energyharvesting covers ranging from table cloths to giant packing for buildings that catch energy from the environment to power sensors and other electronics.P
4、alacios and his colleagues connected a bendy antenna (天线) to a flexible semiconductor (半导体) layer only three atoms thick. The antenna picks up wifi and other radio frequency signals and turns them into a current. This flows into a special semiconductor, where it is changed into a direct electrical c
5、urrent. Researchers have made energyharvesting “rectennas (整流天线)” before, but existing equipment is made from conventional semiconductors which are inflexible, fragile and practically impossible to make in large sheets.The wifi signals can fill an office with more than 100 microwatts of power that i
6、s ripe to be collected by energyharvesting equipment. The MIT system has an efficiency (效率) of between 30% and 40%，producing about 40 microwatts when exposed to signals bearing 150 microwatts of power in laboratory tests. “It doesnt sound like much compared with the 60 watts that a computer needs, b
7、ut you can still do a lot with it，” Palacios said. “You can design a wide range of sensors, for environmental monitoring or chemical and biological sensing, which operate at the single microwatt level.”Medical equipment is another potential application. Because wifi and similar radiofrequency signal
8、s pass through people, energyharvesting covers could be applied to implanted sensors to provide them with enough power to send out health data to an outside receiver.1What does the underlined word “it” in Paragraph 1 refer to?AThe phone.

Fortunately, decades of recovery efforts brought the species back
14、 from the brinka witness to the meaningful milestones that can be achieved through effective conservation. The decline likely began as early as the late 1800s, as both eagle prey and eagles were hunted for the feather trade. By 1960, there were only 400 nesting pairs left in the lower 48.The first e
15、agle protections came from the Bald Eagle Protection Act of 1940, which prohibited the killing or selling of bald eagles. Despite this, populations continued to fall due to the widespread use of DDT in the 1940s and beyondthe pesticide often ending up in rivers, streams and lakes, and gathering in f
16、ish tissue. Birds that fed on these fish laid eggs with such thin shells that they cracked during nesting. In 1967, the bald eagle was listed as “endangered” under the predecessor to the Endangered Species Actthe Endangered Species Preservation Act of 1966. The bald eagle was one of the first specie
17、s to be officially listed under the Endangered Species Act (ESA) when it was signed in 1973.The 1972 ban on DDT made the eagles recovery possible. That recovery was greatly sped up by a combination of regulatory restrictions, nesting site protections, and reintroduction programs, which together cont
18、ributed to a dramatic turnaround for bald eagle populations. The ESA was a critical driver of all of these efforts. In 1995, the bald eagles status was reduced from “endangered” to “threatened，” with an estimated 4,700 nesting pairs occurring in the lower 48 states. A little over a decade later, in
19、2007, the species was delisted with an estimated 10,000 nesting pairs. In 40 years, the bird saw a 25fold increase in its population.
