听力原文： Collecting information about pre-employment and filling out an application form. are closely connected. However, filling out an application form. is much easier because you have total control and have enough time to think and plan. That you are given a form. to fill out does not necessarily mean you have to answer all the questions in it. If the form. contains unclear questions or terms and conditions, you can make some changes before signing it, or refuse to answer some of the questions. What you must realise is that those terms and conditions have been written by highly-paid lawyers. Each word is important, or it would not be there; and you can be sure that there is not anything there that is written with your interests in mind. I know what I speak of, because as a lawyer for Litton Industries, I wrote the terms and conditions that were printed on the back of order forms. I wrote the most tiring terms and conditions anyone has ever seen. Still, 90 percent of the buyers would just sign on them without questioning anything. If anyone questions them, we would reach an agreement on something that was acceptable to both sides. So when you see a preprinted application that contains questions or terms and conditions, read it all and read it slowly. If you dont like something, you can simply change the parts you dont like. Remember that everything can be settled by discussion. To what degree it can be settled depends on your position, of course, and that is something only you can determine. Questions 16 to 18 are based on the passage you have just heard. 16. Why is filling out application forms much easier? 17. What can we learn from the expression 'Each word is important'? 18. What can we infer from the passage?16．
