If we succeed, what will the people say?
Suppose it rains, what shall we do?
Persevere（坚持）and you’ll succeed.
If I were you, I would go.
If you had seen it, you would have been moved.
Unless you try, you’ll never succeed.
Don’t move, or/else/otherwise I’ll shot.
If only I have another chance, I shall do better.
Only in this way can we learn English well.
So/As long as we don’t lose heart, we’ll succeed.
Since that is so, there is no more to say.
Now that you are grown up, you must stop this behavior.
