species的用法及短语

一、species的基本含义及用法

物种（species）是生物学中的一个重要概念，指的是能以自然方式相互交配并繁殖后代的个体集合。而字面上来看，“species”的复数形式为“specii”，但在实际使用中，人们更常用“species”作为单复数通用形式。

在英语中，“species”作为可数名词，其前可以加上不定冠词a或an，并且可以与动词is连用。当我们想要特指某个物种时，可以使用“a species of”或者“this

species of”的形式。此外，“species”还常与其他单词结合构成短语。

二、表示类型和类别的短语

1. Different species：不同物种

Different species refer to various categories or types within the biological

classification system. For example, lions and tigers belong to different species.

2. Endangered species：濒危物种

Endangered species are those that face a high risk of extinction in their natural

habitats due to various factors such as habitat loss, pollution, and poaching.

3. Native species：本土物种

Native species refer to plants or animals that naturally occur in a particular region or

ecosystem. They have evolved over time within that specific environment and play a vital

role in maintaining the ecological balance.

4. Invasive species：入侵物种

Invasive species are non-native organisms that have been introduced into a new

habitat and pose a threat to the local biodiversity by outcompeting native species for

resources.

5. Indicator species：指示物种

Indicator species are organisms that provide important information about the health

and condition of an ecosystem. Their presence, absence, or changes in population can

indicate environmental changes and impacts.

6. Keystone species：关键物种

Keystone species are those whose role within an ecosystem is disproportionately

large compared to their abundance. They have a significant impact on the structure and

functioning of the ecosystem.

7. Protected species：受保护物种

Protected species are those that are legally recognized as needing special

conservation measures to ensure their survival and prevent their decline.

8. Species diversity：物种多样性

Species diversity refers to the variety and abundance of different species within a

given area or ecosystem. It is an essential component of biodiversity and plays a crucial

role in maintaining ecological stability.

三、相关短语和常用表达

1. The presence of multiple species in an ecosystem ensures its resilience against

disturbances.

2. Habitat destruction is one of the leading causes of the decline in many species

worldwide.

3. Conservation efforts are necessary to protect endangered species from extinction.

4. Human activities, such as deforestation and pollution, can have detrimental effects

5. The introduction of invasive species often leads to disruptions in ecosystem

dynamics.

6. Scientists use indicator species as a tool for monitoring environmental changes.

7. Bees are considered a keystone species due to their crucial role in pollination.

8. Laws and regulations have been implemented to safeguard protected species from

exploitation.

9. Preserving species diversity is essential for maintaining the health and resilience

of ecosystems.

International Union for Conservation of Nature (IUCN) classifies endangered

species into different categories based on their risk level.

总结：

“Species”是生物学中一个重要的概念，它指的是能以自然方式相互交配并繁殖后代的个体集合。在英语中，我们常用“species”作为单复数通用形式，并结合其他单词构成各种短语，用以描述不同类型和类别的物种。这些短语包括不同物种、濒危物种、本土物种、入侵物种、指示物种等等，并且每个短语都有其特定的含义和用法。了解这些短语及其用法能够帮助我们更好地理解和使用“species”这一词汇。同时，保护物种多样性也至关重要，以维持生态系统的健康与稳定。在实际应用中，我们需要尊重自然环境和生物多样性，在日常生活中采取积极措施来保护和保持各类不同的物种。
