     In this fast-shifting world, there can be no guarantees attached to any particular job. But there is much

that you can do to protect yourself from the change of society, by equipping yourself with the skills to

manage your career more effectively. You need to be a career activist.

     If you lost your main source of income tomorrow, could you find a different source to replace it? The

most im-portant thing in protecting yourself now and in the future is ensuring that you have choices. Don't

let yourself be held back by a lack of skill development, or fear of change. Some people have been good

performers in their own or-ganization but discovered that they are stuck. Because they are so closely related

to a particular company or indus-try, their skills are not readily transferred to other jobs.

     Don't put all your eggs in one basket. If you limit yourself to one particular area or sector, you limit your

opportuni-ty, too. In a global market place, many jobs come and go quickly as changes in the stock market.

Today's hottest job may not exist tomorrow. If you love computers, then this work represents a great

choice. But don't enter a field just because you think that's where the hot jobs are; even if the job is available,

it may not match well with your own skills and abili-ties. Start with entry of your own strengths and interests,

then see where you may match up best in the job market.

1. How can we ensure that we have choices if we lose the main source of income?

A. Be a good performer in our own organization.

B. Try to develop our skills and be a career activist.

C. Enter a field where the hot jobs are.

D. Transfer to other jobs that use computers.

2. Some people are afraid of change because _______.

A. they have got a hot job

B. they have no other better choices

C. they have got used to a certain job

D. they have no other skills and interests

3. "Put your eggs in one basket" in Paragraph 3 means ______.

A. sticking to only one particular job

B. trying your best to do something well

C. many jobs come and go quickly

D. entering a field where the hot jobs are

4. What is the best job for you to choose according to the writer?

A. Something that is both hot and interesting.

B. Something that brings you good source of income.

C. Something that will always exist in the future.

D. Something involving your strengths and interests.
