1. His face turned red.
2. His face turned like red.
3. He looks pale.
4. He looks like a poet.
(I thinks #3 and #4 are correct. What about #2? Is it correct or wrong?)
#2 is not correct. All the others are fine.
You're right. All are correct except for # 2.
Both sentence #1 and sentence #3 are grammatically correct and convey their respective meanings accurately.
1. "His face turned red." - This sentence is correct because "red" is acting as an adjective here to describe the color of his face. The verb "turned" indicates a change in color, specifically to the color red.
2. "His face turned like red." - This sentence is incorrect because it uses the word "like" inappropriately. Instead, a correct sentence could be "His face turned, like, red." In this case, the word "like" is used as a filler or hesitation, rather than functioning as a comparative word. However, it is more commonly used in informal speech or writing and does not convey the meaning as effectively as simply saying "His face turned red."
3. "He looks pale." - This sentence is correct because "pale" is being used as an adjective to describe his complexion. The verb "looks" indicates his appearance or current state.
4. "He looks like a poet." - This sentence is correct because it uses the word "like" correctly as a comparative word. It suggests that his appearance or demeanor resembles that of a poet.
In summary, #2 is incorrect because it uses "like" inappropriately.
