台湾女诗人淡莹曾经这样说过：“赋予文字新的生命，创造一种诗的语言，乃是当前诗作者急需之务。如果一味______陈腔乱调，那么，终有一天，连你自己都会觉得诗已无存在的必要。从事诗创作是一件艰辛的工作，虽然作者不一定要为它______，但至少应该抱着严谨的态度，相信这也是读者对诗作者的要求之一。一个好的诗作者不能说他只对自己的作品负责，他同时也要对读者负责。”

        1    Very few people choose ideal and perfect jobs for themselves and they do not do the same job for

the rest of their lives. With technology and everything else changing so fast, it's ridiculous to expect to stay

in one job from the time you leave school to the time you retire. Even staying in the same company can be

a huge challenge.   2    

     The first thing you should consider is what kinds of things you enjoy doing and what you are naturally

good at. You have to look at practicality issues. You have to look at what you like to do and take a realistic

look at whether the market is ever going to pay you an income for doing it. Your loving doing something

doesn't mean that the world is going to love giving you money for doing it.   3   And then narrow the list

down by deciding which are at your level. 

       4   For example, if you want to be a doctor, you must graduate with all the papers saying you can be

a doctor. The job requires a high education and an extreme amount of practice.

     Many community colleges have tests that tell you what kinds of work you'd be happy to do.   5   For

example, do you want to travel in your career or stay at home? How much money do you want to make?

After you answer these questions, the computer will show you what careers you would be suited to. Keep

in mind that what interests you at twenty isn't likely to be the same as what interests you at forty. You would

also find some tests online. These will give you some ideas you have never considered.

A. Then how will you choose your first career?

B. What type of jobs are you interested in most?

C. So pick a number of different things that you love at first.

D. Most people's jobs change at least once or twice in their lifetime.

E. They ask you a series of multiple-choice (多项选择的) questions.

F. However, many companies will offer you job training before you start the work.

G. Another thing to consider is how much education or special training s required.
