试题分析：考查句子结构。“while”后接的是现在分词短语，在句中作状语，它逻辑上的主语应该是人，所以可以先排除A、B两项；又因为hear后接复合宾语时，这个复合宾语应包含一个省略to的动词不定式或现在分词短语。句意：当看电视的时候，他们听到门铃响了。故D正确。

Don't you just love ice skating every winter? I am sure, that since winter is approaching, your skates are set to come out, just waiting to be used. Impress your friends with your new trick on how to ice -skate backwards with the help of these tips. Skating backwards on ice is a bit difficult but once you master the basic, there' s nothing like it. Follow the steps given below and you will be able to skate backwards in no time.

Stand Straight

The first thing that you need to do is, stand straight. If you feel that you are falling backwards, then just put your chin up and slightly bend your knees. Don't worry; this happens to all.

Confidence is What You Need

The most important step while learning how to skate backwards, is having enough confidence in yourself and in what you are doing. How can you achieve this? By practice. Just practice rolling backwards down a gentle slop every single day or just by pushing off from a wall or something of that sort. But before you do that, make sure that the place where you are practicing is free from any kind of debris （碎片） because otherwise, you could end up in the hospital due to some accident. While going backwards, just get used to the feeling of moving backwards. One of the important ice skating tips and techniques is that if you feel that you are losing your balance, then scissor （做剪式运动） your skates. Keep practicing this till you are confident about it.

Maintain Speed

Confident now? Great! Now the next step is to maintain your speed. While rolling in a straight line with one skate, with the other try sculling （滑浆）, that is, keep pushing yourself backwards with an outwards stroke （滑动）. Now bring the skate which you were using to scull, and then again, repeat the same process. Make sure that you put most of your weight on the skate which is moving straight and not the one with which you are sculling. Now, try the same thing using the other foot. Again keep doing this till you are confident enough.

Increase Your Speed Now

Once you are confident that you can scull with either foot, the next thing that you have to do is increase your speed. Try some of your own tricks now. Scull with either foot or with both at the same time.

Scull and Be Aware

While you keep one foot straight, keep sculling with the other. You can do that simultaneously （同时，一起） with both feet. Concentrate on what you are doing but don't get so involved that you don't see where you are going. If you are not watching your back, you might just bang against something or someone.
