1.
- What's wrong?
- I have an important exam tomorrow.
- Don't worry too much.
(Is the short dialogue grammatical?)
2. Food also can help people's feelings.
3. Food can also help people's feelings.
(Which one is correct between 2 and 3? Are both OK?)
4. You can get great grade.
5. You can get a great grade.
(Which one is correct between 4 and 5?)
1. Yes
Both 2 and 3 are grammatically OK. Some purists might prefer to keep the modal verb "can" directly in front of the active verb "help", as in 2. The meaning or emphasis of the two is not quite the same. Sentence 2 mentions one of the benefits of food. Sentence 3 refers to food as being one of the ways of helping people's feelings.
5 is corect; not 4.
1. The short dialogue you provided is grammatically correct. However, it would be more idiomatic to add a verb before "Don't worry too much." For example:
- What's wrong?
- I have an important exam tomorrow.
- Don't worry too much about it.
2. The sentence "Food also can help people's feelings" is grammatically correct, but it sounds a bit awkward and might not be the most natural way to express the idea.
3. On the other hand, the sentence "Food can also help people's feelings" is more commonly used and sounds more natural. So, "Food can also help people's feelings" would be the preferable choice between the two options.
4. The sentence "You can get great grade" is grammatically incorrect. It is missing the article "a" before "great grade."
5. The sentence "You can get a great grade" is the correct version. It includes the necessary article "a" before "great grade." So, "You can get a great grade" is the correct option between 4 and 5.
