"He will surely miss the buss." Good except bus not buss. "Fruit go bad quickly in the sun." Should be "Fruit goes bad quickly in the sun.", because "fruit" is a singular noun. "To lift the table he had to go all out." Good. You might add a comma: "To lift the table, he had to go all out." It’s impossible to read this book through at a go. Good, but it sounds a little odd. Better would be: "It's impossible to read this book through in one go" or "It's impossible to finish this book in one go."
