【題目】任務(wù)型閱讀

Saying no can be very difficult. People who are very shy often have little confidence. It is very hard for them to say no. They would feel shy when they say no, but doing things that they don’t want to do will make them unhappy.

A simple and direct “No” is the best way. If you want to explain, you can keep it simple. Just say, “No, I’ve already made plans for this time” or “No, I’m not free at that time.”

Other indirect but polite ways of saying no:

● Sorry, I can’t do this right now.

● I’m afraid I can’t, but thank you for asking.

● Please accept (接受) that I cannot come.

● I’d rather not.

To say no you should:

● Start the sentence with the word “No”.

● Shake (搖晃) your head when you say no to make sure others understand. Your voice should be clear and direct.

Sometimes it is difficult to say no. You can try to reply and explain in the following way:

“Sorry. I would have taken care of your cat next weekend, but I will be going out. I know it will be hard to find someone to take care of the cat. I will try to help you next time.” Remember that: you have the right (權(quán)利) to say no!

根據(jù)短文內(nèi)容，回答下列問題。

【1】Who usually have trouble saying no according to the passage?

________________________________________________________________

【2】How can indirect ways of saying no sound?

________________________________________________________________

【3】When you really want to say “No”, how should you make your voice?

【4】What does the writer encourage us to do?

【5】When it is really difficult to say no, what are you supposed to try to do?
