Hello, I'm an expert in the field of linguistics and I'd be happy to help clarify the usage of the word "grass" in English.
The word "grass" can be used both as a singular and plural noun, but it depends on the context. When referring to the plant itself in a general sense, "grass" is considered an uncountable noun. You wouldn't say "two grasses" when talking about a lawn or a field of grass. However, when you're talking about different types or kinds of grass, you would use the plural form "grasses". This is a more technical or scientific usage and you might hear it in a botanical context.
Let's look at some examples to illustrate the difference:


1. Singular usage (uncountable noun):
- "The lawn needs to be mowed because the grass is getting too high."
- "She loves to lie down on the soft grass and watch the clouds go by."

2. **Plural usage (countable noun for different types):**
- "There are many different grasses native to the African savannah."
- "The botanist is studying the various grasses found in this region."

It's important to note that the use of "grass" as an uncountable noun is more common in everyday conversation, while "grasses" is more likely to be used in a scientific or academic context. However, both are correct and it's all about choosing the right word for the right situation.

Now, let's move on to the translation of the answer into Chinese.
