E "Go for it!" The expression "Go for it! "is a way of encouraging someone to try something. "Go for it! "means you should not worry about failure or be too careful. You should take a chance, be brave, and act firmly. "Go for it! "gets its name from football. Not football as it is played in most countries such as England, Egypt or Japan, but the kind of football played in the United States and Canada. One of the most exciting times in football comes when a team has failed, after three attempts, to move the ball forward ten yards. The team must make a critical decision. The conservative (保守) choice is to kick the ball and accept temporary defeat in order to gain a good position for your team the next time it gets the ball. The more exciting choice, however, is to try a fourth and final time to gain the remaining yards needed. People present are certain to shout their advice. Some will shout: "Kick the ball! "But others will encourage the team to take a chance. "Go for it! "they will scream. In the 1980s, people began using this expression in many kinds of situations to encourage someone to act bravely. There is no guarantee (保证) that the action you"go for it" will succeed. But that is the chance you take when you decide to go for it. You put your fears behind. You choose courage over safety. You hold your breath and go for it. In which of the following situations should we use the expression nowadays
A. We decide to avoid trouble or danger for the future.
B. We try to improve our English for better education.
C. We need to make a quick decision at the last moment.
D. We have to make a choice between success and failure.
