1. A surgeon made a cut in the patient's stomach.

2. A surgeon cut in the patient's stomach.

(Are both the same in meaning?)

3. David took off the poster and cleaned the wall.

4. David took away the poster and cleaned the wall.

5. David took the poster and cleaned the wall.

(What is the difference among the three?)

1 and 2 are very close in meaning, and they'd be closer if you use "into" instead of "in" in 2.

3, 4, and 5 mean the same thing.

1. "A surgeon made a cut in the patient's stomach" implies that the surgeon intentionally created an incision or opening in the patient's stomach, likely for a medical procedure.

2. "A surgeon cut in the patient's stomach" is a shorter and more direct way of expressing the same idea. It also implies that a surgeon performed a surgical incision, but it doesn't provide as much detail as the first sentence.

Generally, these sentences are similar in meaning, but the first sentence offers more clarity by specifying that a deliberate act was performed by the surgeon.

3. "David took off the poster and cleaned the wall" indicates that David removed the poster from the wall, potentially by peeling or lifting it off, and then proceeded to clean the wall afterward.

4. "David took away the poster and cleaned the wall" suggests that David physically removed the poster from its original location, likely by carrying or moving it to a different place. After removing the poster, David then proceeded to clean the wall.

The main difference between sentences 3 and 4 lies in the action of removing the poster. "Took off" implies removing without necessarily changing its location, while "took away" suggests taking the poster to another place.

5. "David took the poster and cleaned the wall" means that David physically picked up or grabbed the poster, but it does not provide any information about what he did with the poster afterward. The sentence solely focuses on the action of taking the poster and cleaning the wall without specifying the outcome of the poster's removal.

In summary, the difference among the three sentences lies in the specific actions and outcomes related to the poster. Sentence 3 focuses on removing and cleaning, sentence 4 emphasizes removing and physically moving the poster, while sentence 5 only highlights taking the poster without indicating further actions.
