（2022·山东日照·一模）Plants don’t have ears or a central nervous system, but new rearch out of the University of Missouri has demonstrated that they might still have the ability to “hear”. More specifically, plants have been shown to exhibit an immune(免疫) respon to the mere sound of a hungry inct.
For the study, rearchers played the sound of a caterpillar chewing to a group of plants, which caud slight vibrations(振动) on the plants’ leaves. The plants were able to recognize the vibration patterns as danger, and responded by mounting the appropriate i
mmune respon. In other words, it appears that plants can “hear” themlves being chewed on.
Rearchers assume that plants achieve this remarkable ability thanks to proteins that respond to pressure found within their cell membranes. Vibrations cau pressure changes within the cell, which can change the behavior of the proteins; however, additional study will be required to confirm or deny this theory.
Once rearchers identify the exact mechanisms at play in this process, it could lead to advances in crop protection. Farmers could potentially learn to u sound to cau a plant’s natural chemical defens against inct threats, rather than turning to poisonous chemicals.
做个有道德的人“We can imagine applications of this where plants could be treated with sound or genetically engineered to respond to certain sounds that would be uful for agriculture,” said study author Heidi Appel.
The study adds to the growing list of ways that plants have been shown to n their environments. They are not the boring organisms that many people assume they are. For instance, some plants are able to communicate with each other and signal upcoming danger to their neighbors by releasing chemicals into the air. Plants can respond to light (think about sunflowers) and temperature. Some can even respond to touch, such as the Venus flytrap(捕蝇草), which snaps shut when an inct stimulates its hairs.
1．Why did rearchers carry out the study?
A．To find out if plants can react to sounds.
B．To learn how plants recognize dangers.
C．To discover if plants can shake their leaves.
D．To e how plants improve immune systems.
2．What’s the potential u of rearchers’ discovery?
A．To remove incts. B．To protect crops.
C．To treat plant dias. D．To produce chemicals.
3．What does the author intend to tell us in the last paragraph?
A．There are more plants than we know.mng
B．Plants are more active than we think.

suit是什么意思（2022·山东潍坊·一模）Being taken off the endangered species list doesn't guarantee a carefree future for whales. Recent rearch estimates that the population of Pacific gray whales off North America's West Coast has dwindled by almost a quarter since 2016. Starting in 2019, alarming numbers of dead gray whales were spotted on beaches and floating offshore throughout their habitat, from Mexico to Alaska. The National Marine Fisheries Service defined it as an “Unusual Mortality Event”. UMEs are declared when a “significant die-off” occurs and when information is collected to clarify why it occurs.
The Arctic has historically low levels of a ice in recent years, upending the delicate ecosystem that sustains gray whales. Like other migrators, they don't feed on their winter breeding (繁殖) grounds or along their migration, and must gain weight during the summer to sustain themlves through the rest of the year. Obrvers using air photography noted the whales looked skinnier and arrived in Mexico in poor condition, wh
ich suggested they were not finding enough food during the summer.
九月九日忆山东兄弟 王维This die-off is alarmingly similar to the events of 20 years ago, when another UME resulted in a significant drop in the gray whale population. Although the cau was ultimately undetermined, it's thought that the population reached “carrying capacity”—it grew too large for the environment to support it. Although that idea has been suggested for this die-off as well, it's more likely blamed on the changing conditions of the Arctic.
Gray whales, hunted almost to extinction by the mid-20th century, were one of the first to be protected from hunting. The Eastern North Pacific population rebounded without pressure from whaling and was taken off the Endangered Species List; the Western North Pacific population is still listed as endangered. This die-off is a reminder that “delisting” doesn't indicate a population's cure future. New threats ari, climate change upends habitats, and continued monitoring is needed in ca a crash comes.
5．What does the underlined word “dwindled” in paragraph 1 mean?
A．Incread. B．Bounced.
C．Multiplied. D．Dropped.
6．What will gray whales usually do in winter?
A．Consume few calories. B．Travel south to breed.
C．March back to Alaska. D．Seek food in the Arctic.
