话题08 动物保护恍然大悟近义词
Passage1
Scientists say baby sharks are at risk of being born smaller and without the energy they need to survive becau of warming oceans from climate change. Scientists studied epaulette sharks, which live off Australia and New Guinea. They found warmer conditions sped up the sharks' growing process, which meant the sharks were born earlier.
John Mandelman, chief scientist of the Anderson Cabot Center for Ocean Life said the findings could be ud in the study of other sharks.
Mandelman said it is widely believed that epaulette sharks are "hardy," or able to survive difficult conditions. "What it means is that this species is more vulnerable than we thought, and this could be true of other sharks," he added.
The scientists studied 27 sharks using the New England Aquarium's reproduction program. Some were raid in average summer water temperatures. Others were raid in higher te
mperatures. They found the sharks raid in warmer temperatures weighed much less than tho raid in average temperatures.
One study this year found that worldwide numbers of oceanic sharks and rays dropped more than 70 percent between 1970 and 2018. Overfishing is a main concern, while climate change and pollution also threaten sharks.
体育明星Carolyn Wheeler, a doctoral student at the University of Massachutts Boston and the author of the epaulette shark study, said while all the sharks survived, tho raid in warmer temperatures were not strong enough to survive for long in the wild. She added that if the sharks are born smaller than usual "they are probably going to have to start looking for food sooner — and they're going to have less time to adjust to their surroundings."
Mariah Pfleger, an ocean scientist said the study should rve as a warning to ocean governing agencies that careful supervision is needed to prevent the loss of more sharks." This study further shows that sharks will not be immune to a warming ocean," Pfl
eger added.

Why did the little boy throw butter out of the window? He wanted to e the butterfly! That’s an old joke you’ve probably heard many times. Butterflies always carry away children.

Most incts do not migrate(迁徙), becau their life is not long enough. Except for one particular butterfly species-the monarch butterfly. Each November, monarch butterflies land on an unbelievable cross-country migration from the United States and Canada until they reach Mexico, where they overwinter until it’s time to begin their migration back home in March. The butterflies spend their time in concentrated areas of forest where they stick to the branches of trees, forming beautiful vast crowds. Monarchs are a truly important species-and they’re in danger. 晒后脱皮
Just like living things, plants, incts or animals on the planet, monarchs play a vital role in the survival of our ecosystems. Butterflies-just like bees, also in great danger-help pollinate(授粉) plants, making them a significant contributor to crop growth and food production. They also rve as a food source to birds and other animals. The population
of monarch butterflies has dropped a lot over the past few decades—a destructive 96. 5 percent. This has placed monarchs in danger of moving toward dying out. Several caus have contributed to the monarch’s decline. Climate change, loss of reproductive homes, and deforestation in Mexico’s forests where monarchs overwinter have all affected the butterfly’s migration pattern and home. But the most significant danger is the decline in milkweed, the plant where monarchs lay their eggs, and that rves as the only food source for caterpillars(幼虫). Much of the milkweed decline is due to agricultural practices that either remove this vital plant or destroy it through pesticides(农药).
