Why have the Americans developed space shuttle according to the passage? [br]
Ever since the Apollo moon landings, the idea of human expeditions to the Mars has come up repeatedly as the kind of grand adventures that would give focus, purpose, and inspirational lift to the space program. But confronted with the cost — estimated at $ 150 billion last week — presidents starting with Richard Nixon and others have flinched and resorted to halfway measures like the shuttle.
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.
选项
A、The term "averted vision" refers to the act of looking out of the corners 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.
答案
C
解析
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 todim 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。
