    Choosing the right job is probably one of the most important decisions we have to make in life, and it is frequently one of the hardest decisions we have to make. One important question that you might ask yourself is: “How do I get a good job?” ____ There are people who can answer an insignificant advertisement in the local paper and land the best job in the world; others write to all sorts of places all over the country, and never seem to get a reply at all. Still others believe that the in person, door-to-door approach is by far the best way to get a job; and then there are those who, through no active decision of their own, just seem to be in the right place at the right time. ____ He used to spend a lot of his free time down by the sea watching the tall ships, but never thinking that he might one day sail one of them. His father was a farmer, and being a sailor could never be anything for the boy but an idle dream. One day, on his usual wandering, he heard the captain of the ship complaining that he could not sail because one member of his crew was sick. Without stopping to think, the lad(少年) offered to take his place. ____.

    ____ If the lad had gone home to ponder(考虑)his decision for a week, he may have missed his chance. It is one thing to be offered an opportunity; it is another to take it and use it well. Sometimes we hear stories about people who break all the rules and still seem to land plum jobs(美差). When you go for a job interview or fill out an application, you are expected to say nice things about the company to which you are applying. ____ And within a year this person had become general manger of the company.

A.This story also illustrates the importance of seizing an opportunity when it presents itself.

B.People find jobs in an infinite number of ways.

C.It's almost impossible to find a good job by answering advertisement in newspapers.

D.Take for example the young man who wanted to be a sailor.

E.But there was one person who landed an excellent job by telling the interviewer all the company's faults.

F.He spent the rest of his life happily sailing the ships he had always loved.

G.It is very important to seize an opportunity when it presents itself.
