All lights______after the students left the classroom.

A．went down

B．goes off

C．goes down

D．went off

解析試題分析：go down表示停止，被接受，沉下，被打敗的意思，而go off表示離開，消失，變差，熄火的意思，所有的燈都熄滅，所以將go down和went down，排除，又根據時間狀語after the students left the classroom.可知答案為一般過去時，故選D
考點：動詞詞組和動詞的時態。

When the traffic lights turn red, we will stop driving a car or crossing a street. Why is red used for traffic lights instead of other colors?
As we know, scattering(散射) happens when light goes through the air. For the same media(媒質), if the wavelength islong, the scattering will be short. If the wavelength is short, then the scattering will be long.
Of all lights we can see red has the longest wavelength, so the scattering is the weakest. That means the red light travels far. In fact, it travels farther on rainy days.
Using the red light can help drivers in farther areas sec the lights. It helps drivers stow down or stop in lime. If drivers don't see the red light until they are close, they may not be able to stop the car in time. An accident may happen Red can also excite people. We can act more quickly when we see the color red. In a word, red lights help drivers stop in time and help prevent accidents.
