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 ply 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.

MR上能清楚显示的组织是

A．心肌

B．心内膜

C．心室、心房

D．主动脉升、弓、降部

E．含气肺组织

如图所示，A、B两物体相距s=7m，物体A以v_A=4m/s的速度向右匀速运动。而物体B此时的速度v_B=10m/s，向右做匀减速运动，加速度a =－2m/s²。那么物体A追上物体B所用的时间为                               （   ）

A．7s

B．8s

C．9s

D．10s

在世界范围来看，优化能源结构的主要途径有().

A.天然气替代煤炭 

B.煤炭替代石油 

C.发展核电 

D.发展水能，风能等可再生能源

变压器温度的测量主要是通过对其油温的测量来实现的。如果发现油温较平时相同负载和相同条件下高出10℃时，应考虑变压器内发生了故障。（）
