I must be confused by the different pronunciations of "like" in different words.

A very simple method:

In general, "like" is pronounced as Si, which is similar. It looks like flowers are specious. Relatively speaking, giving is less, for example, liking. More suitable for beginners to understand.

A deeper understanding, when reading s √, has similar meaning, as if, comparison. When read as "yes", it often refers to the meaning similar to a certain situation or thing, and you need to understand it yourself.
