1. You can reach anyone all over the world.

2. You can get in touch with anyone all over the world.

(Are both the same? What is the meaing of 'reaach' in Sentence 1?)

3. Probably he will come.
4. Possibly he will come.
5. Maybe he will come.

(What is the difference among them? Do they have the same meaning?)

6. Do you have an appointment tonight?
7. Do you have a promise tonight?
(Are both the same?)

8. In my opinion, we should help poor people.

9. As for me, we should help poor people.

10. As far as I am concerned, we should help poor people.

(Are the three sentences the same in meaning?)

1 and 2 mean the same, yes. In #1, "reach" means to contact, most likely by telephone.

3 would be OK if you move some words around: He will probably come.

4 is OK, but not used often.

5 is perfect!

6 and 7 do not mean the same thing at all. 6 is correct; 7 is not used.

8, 9, and 10 are all about the same, yes.

1. "Reach" in sentence 1 means to make contact with or communicate with someone. So, in this context, it means that you can contact or communicate with anyone all over the world.

2. Sentence 2 has a similar meaning to sentence 1. "Get in touch with" also means to make contact or communicate with someone. So, both sentences convey the idea of being able to communicate with anyone regardless of their location.

Regarding the second set of sentences:

3. "Probably he will come" implies a higher degree of certainty that he will come. It suggests that based on the available information or circumstances, it is likely that he will come.

4. "Possibly he will come" suggests a lower degree of certainty. It means that there is a chance or possibility that he will come, but it is not certain.

5. "Maybe he will come" is similar to "possibly." It indicates uncertainty and implies that there is a possibility that he will come, but it is not definite.

So, while all three sentences express uncertainty about whether someone will come, there are subtle differences in the level of certainty conveyed.

Regarding the third set of sentences:

6. "Do you have an appointment tonight?" refers to a scheduled meeting or arrangement with someone at a specific time.

7. "Do you have a promise tonight?" is not a commonly used phrase. It does not convey the same meaning as an appointment. It seems to suggest a promise made between two people with an expectation of fulfilling it, but it may not be used in the same context as an appointment.

Therefore, sentences 6 and 7 are not the same in meaning, as "appointment" and "promise" have different implications and contexts.

Regarding the fourth set of sentences:

8. "In my opinion, we should help poor people" signifies that the speaker is expressing their own viewpoint or belief that helping poor people is the right course of action.

9. "As for me, we should help poor people" is another way of expressing the speaker's personal opinion or belief on the matter.

10. "As far as I am concerned, we should help poor people" also indicates the speaker's own perspective or opinion on helping poor people.

All three sentences convey the general idea that the speaker believes helping poor people is important. However, they may slightly differ in the emphasis or context of the speaker's opinion.
