上期划线句答案
Individuals may find themselves in online communities that encourage the sharing of similar viewpoints or tonal language, which is when a phrase is dependent on the pitch or tone with which it is spoken, according to a 2024 study.
根据 2024 年的一项研究，人们可能会发现自己身处一些鼓励共享相似观点或使用语调语言（即根据说话音高或语调而决定含义的语言）的在线社区。
注：语调语言指的是不同声调的同音字代表不同意思的语言（例如中文）。这里可以延申理解为即使同一句话也可能有不同含义，例如“我很好”可以表达“好”和“不好”之意，因此这里强调说话的调性、情绪或者真实含义也一致。

Para.1
Rocks crumble into the sea as sand. Similarly, the ocean is an inevitable destination of disintegrating human rubbish: microplastics. Much like a natural sediment, these tiny synthetic granules also make their way into the bellies of the creatures that call the sea home. But one tiny organism, notorious for its ability to return to life after a trip to space, being frozen or boiled, asphyxiated, even bombarded with radiation, seems to have yet another hidden ability up its wee sleeves. In a study of diverse tiny creatures, tardigrades were seemingly immune to swallowing microplastics.
Para.2
A team led by zoologist Flávia de França from the Federal University of Pernambuco in Brazil collected samples of meiofauna – intertidal invertebrates between around 45 micrometers to 1 millimeter – from the shallow sediments of a sandy beach on the northeastern coast of Brazil at low tide.
Para.3
Within these samples they found 5,629 individual organisms, including nematodes, segmented worms, flatworms, bristleworms, seed shrimp, hairybellies, mites, crustaceans and their larvae. And let's not forget the celebrity of the universe: the tardigrade. These critters were kept in tanks designed to mimic the natural environment as best as possible, along with 100 grams of sediment containing varying degrees of plastic particles.
Para.4
With a radius of around one thousandth of a millimeter, the fluorescent polystyrene microspheres can technically be categorized as 'nanoplastics', but the authors decided not to differentiate these from larger microplastics in light of ongoing debates around the size limits of these particles.
Para.5
Analysis revesaled all of the tiny creatures swallowed the microplastics except for the tardigrades, which seemed to have the unusual ability to dodge these dubious particles. They didn't come away completely plastic-free, however. More than half of the waterbears were seen sporting microplastic particles on the surface of their bodies, particularly on their 'legs' (or to be more scientific, their locomotory appendages). It's important to note that there is a wide variety of tardigrades, many with differently-shaped body parts, so not all may be protected from our disintegrated rubbish in this way.

阅读理解题
According to the study, which of the following best describes the interaction between tardigrades and microplastics?
A) Tardigrades readily ingest microplastics, similar to other meiofauna.
B) Tardigrades completely avoid contact with microplastics in their environment.
C) Tardigrades do not ingest microplastics, but may have them attached to their bodies.
D) Tardigrades digest microplastics, breaking them down into harmless substances.

全文概括
A Brazilian study examined the ingestion of microplastics by various meiofauna organisms. Researchers found that while most organisms, including nematodes and crustaceans, consumed the microplastics, tardigrades surprisingly avoided ingesting them, though some showed microplastics adhering to their bodies. The study used fluorescent polystyrene microspheres in a controlled environment mimicking natural conditions. The findings suggest potential differences in microplastic interaction among various species. Further research is needed to determine if this avoidance is consistent across all tardigrade species and the implications of external microplastic attachment.
