1. 提问方式

推断文章出处的设题形式有：

The passage is most likely to be taken from______.

Where would this passage most probably appear?

The passage is most likely a part of______.

2. 解题技巧

这类问题应从文章的内容或结构来判断其出处：

(1)报纸：前面会出现日期、地点或通讯社名称。

(2)广告：因其格式特殊，容易辨认。

(3)产品说明：器皿、设备的使用说明会有产品名称或操作方式，而药品的服用说明会告知服用时间、次数、药量等。

3. 实例分析（全国卷）

Do you always understand the directions on a bottle of medicine? Do you know what is meant by “Take only as directed?” Read the following directions and see if you understand them.

To reduce pain, take two tablets(药片) with water, followed by one tablet every eight hours, as required. For night-time and early morning relief (缓解疼痛) take two tablets at bedtime. Do not take more than six tablets in twenty-four hours.

For children six to twelve years old, give half the amount (量). For children under six years old, ask your doctor’s advice.

Reduce the amount if you suffer from restlessness or sleeplessness after taking the medicine.

●This text is most probably taken from a ______.

A. textbook                   B. newsreel            C. doctor’s notebook            D. bottle of medicine

【解题思路分析】此题极易误选D。的确，人们常在药瓶上的说明中看到文章直接引语部分的文字内容，但是像第一段这样的内容不可能出现在药瓶上。由此可见，这一段文章应选自教科书中有关如何读服药说明的课文，故选A。
