Question

Tigers are good AT swimming Почему at, а не of/in/on?

все легко:

слово good само по себе означает хорошо, хороший, а если мы имеем в виду, что человек хорош в чем то, например он хорош в математике, то будет так

He is good at math

Answer 2

In the sentence "Tigers are good at swimming," the preposition "at" is used to indicate proficiency or skill in a particular activity. "At" is commonly used to talk about someone's ability to do something well or perform a specific action competently. It is used with various activities, sports, and skills.

Let's break down the options you suggested:

1. Tigers are good at swimming. - Correct usage: This means that tigers have a natural ability or skill when it comes to swimming. They are proficient swimmers.

2. Tigers are good of swimming. - Incorrect usage: "Of" is not used to indicate skill or proficiency in an activity. It is more commonly used to show possession or belonging. For example, "The roar of the tiger."

3. Tigers are good in swimming. - Incorrect usage: "In" can be used to talk about participating in a general sense, but it doesn't convey the same sense of proficiency or skill as "at." For example, "Tigers enjoy playing in the water," but it doesn't emphasize their competence as swimmers.

4. Tigers are good on swimming. - Incorrect usage: "On" is not used in this context to express proficiency in an activity. It is used to indicate physical location or contact, like "The tiger is sitting on the rock."

So, "at" is the appropriate preposition in this sentence to convey that tigers are skilled or proficient at swimming.
