If the sun did not ____ heat, the temperature of the earth would fall almost to absolute zero.
举一反三
- If the inflation rate is zero, then A: both the nominal interest rate and the real interest rate can fall below zero. B: the nominal interest rate can fall below zero, but the real interest rate cannot fall below zero. C: the real interest rate can fall below zero, but the nominal interest rate cannot fall below zero. D: neither the nominal interest rate nor the real interest rate can fall below zero.
- Why does the earth become cool? A: Because the sun gives the heat to the earth. B: Because the moon gives the wind to the earth. C: Because the earth rotates . D: Because the sun's heat bounces to the space.
- It is too cold today and the temperature may fall ________zero. A: under B: over C: below D: above
- Absolute zero is the lowest limit of the thermodynamic temperature scale. Once it is achieved, the substance may demonstrate special properties.
- S3. If the temperature at the earth’s surface is 20F, the temperature in a coal mine 500 feet below the surface would be _____________________.
