【填空题】Mr.King ’ s Working Trouble I graduated two years ago with a bachelor ’ s degree in media studies. And after my graduation, I applied for jobs in film and television. I knew it was a competitive area, but I wanted to have a try. At first, it was depressing, because I didn ’ t get one interview. Everyone wanted me to have work experience. But how can you experience work if nobody gives you a job? I was so unhappy at that time. In the end, I did unpaid work for a company in public relations. To begin with, I hated it. I only did boring jobs like making coffee for people and photocopying. But recently I ’ ve started doing something more interesting. For the time being, I ’ m helping my company to advertise an American film. I can have a chance to put what I ’ ve learned into use. However, I ’ m not happy because I ’ m working for no money. Sometimes, I think the company is exploiting me. If they don ’ t offer me a paid job soon, I ’ m going to start looking for something else. Find the information in the passage to fill in the blanks: 1.Name: 2.Degree: 3.Apply for the jobs: 4.First feeling: 5.Boring jobs like: 6.Work for the time being: 7.Reasons for being unhappy:

【填空题】Plan Your Future Career Wisely Whatever you ’ re just entering college or preparing for graduation, it ’ s time to start thinking about your career. Try to avoid making the following two mistakes when you are planning your future career. C onfusing what you ’ re good at with what you like to do. You don ’ t have to spend your life singing at weddings just because you have a silky voice. Nor do you have to become a chef because you have a gift with spices. To start your career search, jot down two lists: one listing what you ’ re good at, and another listing things you love to do. Though it might require more soul searching, the list of what you enjoy is the most important. Why? Because if you enjoy doing something , you ’ ll do it for more than just a regular paycheck. You ’ ll do it more often and invest in training. You ’ ll do it even when it ’ s difficult. You ’ ll do it until you ’ re good at it. Confusing avocations with vocations. So you ’ ve made your lists and discovered you love running, law, reading and basket weaving. Now you ’ re scratching your head, puzzling over how to combine all of these aspects into one job. Don ’ t worry —— you don ’ t have to. Believing your job has to satisfy the whole you is a common source of career error. It does not mean you can ’ t love your job —— you can just have a lot of activities and hobbies (avocations) on top of it. For example, you may love dancing but you know you can ’ t earn enough with dancing as a career. Dance, then, is a great avocation for you. You can continue to dance for fun, but separately form your day job. A final note: Think creatively when considering which job to pursue after graduation. Your options are more varied than you might think. True or false ( )1 、 To start your career search, you can jot down what you ’ re good at, and what you love to do. ( )2 、 If you like doing the thing ,you are willing to do more and invest in training. ( )3 、 You needn ’ t worry about how to combine all of these aspects into one job. ( )4 、 The passage is mainly about making a list in career planning. ( )5 、 You should not have any hobbies because you have to do well in your job.
