Directions: Read the following text and choose the most suitable heading from A-F for each paragraph.
There is one extra heading which you do not need.

A. Who does freelancing?
B. The advantages and disadvantages of freelance
C. The definition of freelance
D. Key to freelance success
E. What is freelancing really like?
F. The best way to develop a career

1._____
     Freelance is a word that goes back to medieval times when it was used to describe soldiers who sold their
skills to those prepared to pay their market rate. Today it's an increasingly common way of working for people
in a range of occupations and appeals to many who feel constrained by corporate culture.
2._____
     What you gain is freedom of movement, what you can lose is a sense of belonging. You can end up feeling
isolated from normal support networks, because suddenly you are responsible for your own welfare, training,
safety, career development, equipment, professional updating and a thousand other things, it is easy to remam
unaware of these things in the relatively cosseted existence of full-time employment. So before you leap up into
this exciting and potentially rewarding way of working, stand back and take a look at the risks.
3._____
      Freelancing has always been a common way of working for writers, artists and performers, but the range
of occupations with a substantial number of freelancers is growing steadily. Anyone with a marketable skill can
choose to go it alone. Websites offer a free directory listing for those with skills to sell. Their categories include
accountants, healthcare consultants, landscape architects and computer trainers. Areas of work that have
problems recruiting staff are always keen to employ freelancers.
4._____
     Being a freelance is different from other forms of self-employment-you still work for an employer or several
employers but have to develop a completely different set of relatjonships with them. Employers are now your
customers, you are their supplier. You have to become indispensable to them, providing solutions to their
problems, some of which they may not even realize they have. In many ways you have to behave like their
dream employee, being more willing and available than you may have got used to while in a "proper job".
5._____
     You also have to be aware of, and sensitive to, the fact that you can be seen as a threat by your customer's
conventional employees, who may regard you as taking work they can do. Successful freelancing relies on the
cooperation of everyone you come into contact with. Work that brings you into conflict with an existing
workforce can be more trouble than it's worth.
