【题目】根据短文内容,从短文后的选项中选出能填入空白处得最佳选项。选项中有两项是多余选项。请将选项写到答题纸上。

It is said that there are about 40,000 different kinds of jobs in the world. 【1】Finding a job is not the same as choosing a job. Many young people end up in a job which they are not suitable for. 【2】 Here are a few steps to help you think about jobs which you might enjoy doing after school or university.

First, it is important to realize what kind of person you are, which special qualities make you different from everyone else and what you are interested in . 【3】If you like art and enjoy looking at pictures, this is an interest. But if you can draw a horse that looks like a horse instead of a big dog, that is a skill.

Then ask yourself this question: in the following three areas----skills with people, skills with information and skills with things-----which are your best skills?

After examining your skills, the next step is research. To find out as many different kinds of jobs as possible, go to the library and read books, magazines and newspapers. 【4】

Finally, trust your own ideas and your own thinking! 【5】

A.It is your own life, so find something that you enjoy doing.

B.Choosing the right one itself is a difficult job.

C.We must know what our ideal jobs are.

D.There is a difference between an interest and a skill

E. Ask your friends about the work they do.

F. “Chance” may play a more important part than “decision”.

【题目】根据短文内容,从下框的AF选项中选出能概括每一段主题的最佳选项。选项中有一项为多余选项。

A. Be ready for the questions to be asked.

B. Take copies of your resume to the interview.

C. Think about your education and the skills you have learned.

D. Good preparation before the interview.

E. Come to the interview with personal information.

F. Try to get to know more about the company.

【1】Preparation is a big part of the interview process. You will, or you should, spend more time getting ready for the interview than you will at the interview itself. This preparation includes getting to know more about the company and the position you are applying for, and preparing yourself to explain how your valuable qualities make you the best person for the position. And of course, there is the time it takes to make yourself presentable. Job interview can be a stressful situation for many people. The best way to help relieve this stress is to hold a positive attitude and be well prepared. Consider the following tips as you prepare for your interview.

【2】Think of the answers you want to give. Although you will never completely know in advance every question they will ask you, there are questions that get asked in almost every interview. Learn what they are and try to predict what the others might be. Interview questions are usually sourced from the job posting. If they are looking for a particular skill set, make sure you can explain how you will meet that expectation.

【3】Do your best to get information about the company before the interview. Do some research, such as using their website, scanning through annual reports if they publish one, being familiar with the project they are now working on. This will help you to present your answers in the context of what their core business is about.

【4】Most job postings have a list of core duties or responsibilities as well as what qualifications are required. Study these well and prepare your answers accordingly. Think about what education and training you have had and what work experiences you have done that makes you the ideal person for the position. Be thorough in your self-assessment, think broadly about all you have learned and experienced. You may surprise yourself with what skills you have acquired previously.

【5】In most cases, the interviewer will have your resume already, but it never hurts to have some back-up copies just in case. And be sure they are the most current and relevant resume for the position.
