1. It seems that he is rich.

(Is the that clause a subjective complement?)

2. My car is similar to yours.
3. My car resembles yours.
4. My car takes after yours.
5. My car looks like yours.
6. My car is like yours.
(Are the five sentences all the same in meaning? Which ones are not commonly used?)

1. A subject (not subjective) complement ... yes.

2 - 6 -- All are grammatically correct, but 4 would be used only when referring to people, not things. "My nephew takes after his dad."

1. The clause "he is rich" in the sentence "It seems that he is rich" is not a subjective complement. A subjective complement is a word or phrase that follows a linking verb (e.g., "is," "seems," "appears") and describes the subject of the sentence. In this case, the subjective complement would be "rich" if the sentence were structured as "He seems rich."

2. "My car is similar to yours," 3. "My car resembles yours," 4. "My car takes after yours," 5. "My car looks like yours," and 6. "My car is like yours" all convey a similar meaning, which is that there are similarities between the speaker's car and the other person's car. However, there are slight differences in usage and connotation:

- "My car is similar to yours" is a straightforward statement indicating a likeness or resemblance between the two cars.
- "My car resembles yours" also conveys a likeness or similarity, but it may imply a stronger resemblance or a similarity in appearance.
- "My car takes after yours" suggests that the speaker's car has adopted some characteristics or traits from the other person's car, often used figuratively to describe a familial or inherited resemblance.
- "My car looks like yours" emphasizes the visual resemblance between the two cars.
- "My car is like yours" is a general statement indicating a similarity without specifying the particular aspect of similarity.

Among these sentences, "My car resembles yours" and "My car takes after yours" may be less commonly used in everyday conversation compared to the others, but they are still grammatically correct and can be used in appropriate contexts.
