1. I watch a comic drama on TV when I feel blue.

2. I watch comic drama on TV when I feel blue.

(Which one is correct? Is #2 not correct?)

3. Mike is idle. Plus, he never exercises.

(Is this correct? Which expression can we use instead of 'Plus'?)

4. He is a mouse potato.
(Do you use this expression? What is the meaning of this sentence?)

5. Don't close your eyes where I take a picture.

6. Don't close your eyes when I take a picture.

(Which one is correct in #5 and #6?)

7. Stand in a line.
8. Stand in line.

(Which one is correct? Are both OK?)

9. He wins every time.
10. He wins at every time.
(Which one is correct? Can we use 'at every time' in this sentence or in other sentences?)

11. He put the fire out.
12. He extinguished the fire.
(Are both the same? do you have other similar expressions?)

1 and 2 are both correct (with or without the "a"), but rather than saying "comic drama" you should just use the term "comedy."

3 is OK, but if you substitute "In addition," for "Plus" you'll have a better sentence.

4 should be "He is a couch potato." The expression means that he sits or lies on the couch all day (probably watching TV!) and doesn't do much else. It also sometimes implies that he's getting fatter as a result.

5 is not correct, but 6 is.

7 and 8 are both fine. 7 implies that people are just now forming a line; 8 implies there's already a line and the person should join it.

9 is correct; 10 is not. The word "at" is not needed.

11 and 12 mean the same thing. Some times the wording in 11 is changed around: "He put out the fire."

1. Both sentences are grammatically correct, but they convey slightly different meanings. Sentence #1 implies that the person watches a comic drama specifically on TV when they feel blue. Sentence #2, on the other hand, could mean that the person watches a comic drama in general when they feel blue, without specifying whether it is on TV or any other medium. Both sentences are acceptable, but the choice depends on the intended meaning.

3. The sentence "Mike is idle. Plus, he never exercises." is grammatically correct. However, you can use alternative expressions instead of "Plus" to convey the same idea. For example, you could use "Furthermore," "Moreover," or "Additionally" instead of "Plus" to indicate that Mike's lack of exercise is another contributing factor.

4. The expression "mouse potato" is not commonly used. The more commonly used expression is "couch potato," which refers to a person who spends a significant amount of time sitting or lying down, typically watching TV or engaging in sedentary activities. So, the sentence "He is a mouse potato" would be unusual and might not be readily understood. Instead, you should use "He is a couch potato" to convey the intended meaning.

5. Both sentences, "#5 Don't close your eyes where I take a picture" and "#6 Don't close your eyes when I take a picture" are grammatically correct. However, sentence #6 is more commonly used and preferred. It suggests that the speaker wants the person being photographed to keep their eyes open while the picture is being taken.

7. Both sentences, "#7 Stand in a line" and "#8 Stand in line" are correct. The choice between the two usually depends on regional variations or personal preference. In American English, "Stand in line" is more frequently used, while in British English, "Stand in a line" is more common. However, either form can be understood in both dialects.

9. The correct sentence is "#9 He wins every time." The phrase "every time" implies that he consistently wins without exception. You cannot use "at every time" in this sentence as it would be grammatically incorrect. However, "at every time" could be used in other contexts, such as "She arrives precisely at every time scheduled."

11. Both sentences, "#11 He put the fire out" and "#12 He extinguished the fire," convey the same meaning. They both indicate that he took action to extinguish the fire. Alternative expressions with similar meanings include "He doused the fire" or "He quenched the fire," which also imply the act of extinguishing.
