A summary of the physical and chemical nature of life must begin, not on the Earth, but in the Sun; in【C1】______at the Sun’s very center. It is here that is to be found the【C2】______of the energy that the Sun pours out into space is【C3】______The energy takes the form of light and heat. This energy is【C4】______at the center of the Sun as billions【C5】______billions of nuclei of hydrogen atoms【C6】______with each other and fuse together to form nuclei of helium, and in doing so,【C7】______some of the energy that is【C8】______in the nuclei of atoms. The【C9】______of light and heat of the Sun【C10】______that some 600 million tons of hydrogen be【C11】______into helium(氦)in the Sun every second. This the Sun has been doing for several thousands of millions of years. The nuclear energy is released at the Sun’s center as high-energy gamma radiation,【C12】______of electromagnetic radiation like light and radio waves, only of very much shorter【C13】______. This gamma radiation is absorbed by atoms inside the Sun to be【C14】______at slightly longer wavelengths. This radiation, in its【C15】______is absorbed and reemitted. As the energy filters through the【C16】______of the solar interior, it passes through the X-ray part of the spectrum【C17】______becoming light. At this stage, it has reached what we call the solar surface, and can escape into space without being absorbed further by solar atoms. A very small【C18】______of the Sun’s light and heat is emitted in such directions that【C19】______passing unhindered through interplanetary space, it【C20】______the Earth.
【C9】
选项
A、outlaw
B、outlook
C、outset
D、output
答案
D
解析
名词辨义题。该句意在说明“太阳所产生的光和热需要每秒将六亿吨氢转化为氮”。光和热的“产生”可用output来表示。outlaw意为“歹徒,亡命徒”;outlook意为“观点,前景,展望”;outset意为“开始,开端”。构词法相近,但意思差别较大,可排除。
