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 important 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 organization but discovered that they are stuck.Because they are so closely related to a particular company or industry，their skills are not readily transferred to other jobs.

(2010届英语周报第19期)
About 4 years ago，as a newly appointed general manager for a chemical plant near Toronto，I was faced with several leadership challenges.When I was first appointed as acting general manager，the plant was not even covering its costs and I was told that it would either be turned around or else!
I met with all employees and explained the severity (严峻) of the situation and that we would all need to do what we could to increase sales and improve performance or reduce operating expenses.They all appreciated my honesty although they were very nervous about their futures.
I then started working with each department head to determine how I could support their efforts.At first，they thought that I was looking to fix the blame for inefficiencies，but over time，they realized that I only wanted to help them find solutions.
They learned to trust me；as when things sometimes went poorly，I told my boss that I was the person in charge rather than pointing my finger at one of my members of staff.When we gained new business and it directly improved our bottom line，I praised the efforts of the entire team.
The plant workers became more and more motivated and now they all seem to really enjoy their jobs and I feel honored to be their leader.Do we still have challenges？Yes，but the strength of the team is such that we all pull together to face them “as one”，kind of like a family facing life’s ups and downs.
5．When the author became the general manager，the plant________.
A．could only make ends meet
B．had a strong management team
C．was really in bad situation
D．was planning to enter other fields
6．When the author came to the plant the first time，he impressed the employees with his________.
A．practical attitude B．intelligence
C．diligence D．politeness
7．Every time things didn’t go well，the author would________.
A．take the blame himself
B．ask his staff to take responsibility
C．get very depressed
D．think of ways to increase sales
8．The passage offers a good example of________.
A．being a good employee
B．being a good leader
C．reducing operating expenses
D．the importance of honesty
