Which of the following statements is NOT true according to the passage a. The term "averted vision" refers to the act of looking out of the comers of one’s eyes. b. If you want to see very faint things, you should better look sideways rather than straight on. c. The receptors located in the eye’s center are less sensitive to dim light. d. To "look" is to see something straight ahead.
参考答案：C
解析：[听力原文]It’s amazing what you can see when you don’t look. Astronomers often practice a technique known as averted vision to see very faint things. By looking to the side rather than straight on, they avoid using receptors in the eye’s center, which are more sensitive to dim light. So canny stargazers try to see the wonders of the cosmos out of the corners of their eyes.
[分析]： 比较结构的识别和理解。 同原文“they avoid using receptors in the eye’s center, which are more sensitive to dim light”比较中看，显然选项c的说法正好与此相背，因此，选项c是正确答案。[解题关键] 掌握所比较的对象之间的关系是该题解题的关键。
