A. top B. bottom C. side D. centre——青夏教育精英家教网—

　　As you look up at the moon, you can use a simple trick （戏法）to find out if it's waxing or waning. We can tell the moon is waxing when it's on its way to becoming full. We can tell the moon is waning when it's losing silver each night.

　　Here's the trick. Look at the moon, and draw an imagining line where the centre would be if the moon were full. Start at the bottom, and draw the line up the middle and past the top of the moon. The line and the lit side of the moon will form either a lower case of “b” or “d”.

　　The “b” stands for “baby”. The baby moon is on its way to full moon phase （阶段）. It will appear to grow each night until it is perfectly round.

　　The “d” stands for “dying”. The dying moon is headed toward the new moon phase. It will seem to become smaller each night until it can no longer be seen in the sky.

　　As the moon travels round the earth the moon appears to change shape. But in fact, the sun is simply lighting up different parts of the moon.

　　No matter what phase the moon is in, you can use this trick. Every time, you'll find that you're right about what the moon will do next.
