长对话与短对话相比，虽然长度增加，但难度大大降低。今天，易哲老师就教大家一个实用性极强的做题技巧，帮助大家在长对话这个部分拿到一个比较理想的分数。

这个技巧就是所听即所选原则。它的含义是：

‘

若某选项中有两个实词（含）以上被完全听到或同义替换，则该选项为正选。

这句话中，有两点需要我们注意。

一是“两个实词（含）以上”。这要求我们在听长对话时，对于听到的实词，一定要打勾，这样才不会遗漏。这里的实词指的就是英语中的名词、动词、形容词、副词、数词、代词。

二是“被完全听到或同义替换”。这告诉我们“完全听到”为简单题，一定要做对，而“同义替换”为难题，需要我们平时积累常见的替换表达。

W: What sort of hours do you work, Steve?

M: Well, I have to work very long hours, about eleven hours a day.

W: What time do you start?

M: I work 9 to 3, then I start again at 5:30 and work until 11, six days a week. So I have to work very unsocial hours.

W: And do you have to work at the weekend?

M: Oh, yes, that’s our busiest time. I get Wednesdays off.

W: What are the things you have to do and the things you don’t have to do?

M: Uh, I don’t have to do the washing-up, so that’s good. I have to wear white, and I have to keep everything in the kitchen totally clean.

W: What’s hard about the job?

M: You are standing up all the time. When we are busy, people get angry and shout, but that’s normal.

W: How did you learn the profession?

M: Well, I did a two-year course at college. In the first year we had to learn the basics, and then we had to take exams.

W: Was it easy to find a job?

M: I wrote to about six hotels and one of them gave me my first job, so I didn’t have to wait too long.

W: And what’s the secret of being good at your job?

M: Attention to detail. You have to love it. You have to show passion for it.

W: And what are your plans for the future?

M: I want to have my own place when the time is right.

Q19 What does the man say about his job?

Q20 What does the man think is the hardest part of his job?

Q21 Where did the man get his first job after graduation?

Q22 What does the man say is important to being good at his job?

第19题为简单题，我们可以明显听到work long hours这三个实词，从而快速选出正确答案B。

第20题为难题，我们可以听到standing up all the time和people get angry and shout，从而推测出男士工作中感到最困难的两点是：一、体力（physical endurance）；二、耐心（patience），对应正确答案D。该题考察同义替换。

第21题为简单题，我们可以明显听到hotel这个地点，从而快速选出正确答案D。

第22题为简单题，我们可以明显听到Attention和detail这两个实词，从而快速选出正确答案B。

所听即所选原则可以广泛运用于四级长对话中，大家平时做题要好好注意。
