[填空题]Where is the heating element fixed in the scissors It is fixed in the ______ of the edges.

[单项选择]In household electric ovens, the heating element has only two settings—on and off. A thermostat connected to the oven’s temperature knob is the only control on temperature, automatically switching the element off when the indicated temperature is reached, which happens quickly in modern ovens, and subsequently on or off as needed to maintain temperature.
Which of the following statements is most strongly supported by the information above
A. Because in each case the heating element alternates between on and off, a modern household electric oven uses little more power at its maximum temperature setting than it does at its lowest temperature setting.
B. Once the indicated temperature has been reached and is being maintained by the thermostat, the heating element will be switched off for a greater proportion of the time than it is switched on.
C. The accuracy with which household electric ovens main rain their temperature could not be improved on by ovens whose heating elements have more than two settings.
D. In a correctly functioning modern household electric oven, the thermostat will generally not switch the heating element off when the oven’s temperature is more than a few degrees above the indicated temperature.
E. (E) If the thermostat of a modem household electric oven is disabled so that the heating element remains switched on, the oven’s temperature can eventually become higher than the maximum temperature setting on its temperature knob.

[单项选择] Home Heating
Central heating became popular only after the Civil War. Typically, coal-burning furnaces (火炉) fueled the early systems. Natural gas had developed into the leading fuel by 1960. Its acceptance resulted in part from its wide uses. Because it comes primarily from U.S. and Canadian fields, natural gas is also less vulnerable (脆弱的) than oil is to war. Oil remains the most important fuel in a few areas, such as New England.
Electric heating dominates most areas with mild winters and cheap electricity, including the South and the Northwest. It was made popular at least in the South by the Iow cost of adding electric heating to new houses built with air-conditioning. Bottled gas, which is somewhat more expensive than utility gas, is the fuel of choice in rural areas not served by utility pipelines. Wood is the leading heating fuel in just a few rural counties.
