归途

①出站后,我直奔售票处,买好回部队的车票。真是春风得意,这次多亏在邮局工作的老同学"帮忙"，拍了封"母病危，速回"的电报，要不，谁知道猴年马月探一次亲呢！

②刚离开售票口，那个一直守在边上的老人突然拉住我："去宁波？"我点点头，忽然明白了什么，甩掉了他的手继续朝前走。

③"探亲还是出差？"他紧追不舍。"回部队。"我爱理不理的。说实在的，经常出门在外，这种人见多了，我猜得出再搭上两句话，他就要说"到部队看儿子，钱被偷了。想借点路费，回去寄还"这一类话，可能还会挤出几滴眼泪，最后还可能拿出一个证件，但其真假只有天知道。猛然，他跑到前面拉住我："解放军同志，想求你一件事儿……"一听这话，我差点儿笑出来，随手指了指不远处一个民警："找他去吧！"

④老人一怔，说："不，我想请你回部队替我发个电报。"说着，递上一个信封和10元钱。我抽出信纸，上有一行短语："妈，儿因部队需要不能回家并到医院服侍你老人家，请妈原谅！小强于宁波。"

⑤我疑惑地抬起头，仔细打量老人："你自己可以拍电报给你儿子，像这种情况，部队领导会考虑的。"

⑥许久，老人才缓缓地说："他妈患的是绝症，这几天一清醒过来就要儿子，而小强却在两个月前因公牺牲了，没办法，只好……"

⑦啊！是这样，我一时竟不知该说什么好，手上的信变得异常沉重，仿佛捧着一颗跳动的心。

⑧"我还要到医院去，这件事儿拜托了。"说罢，他双手为我扶正军帽，抚平衣折，转身融入熙熙攘攘的人流之中。

⑨望着人流中的老人，我庄严地举起右手……

A recent Auburn University study provides some real numbers to back a theory we’ve all known was true for some time—planting a shade tree near your home reduces energy bills significantly in the spring and summer months. The study, conducted in Auburn,

Alabama, included 160 homes with different levels of shade. Each home’s energy usage was monitored and compared to other houses with similar energy— using patterns, size, type of cooling system, etc. Here are some highlights from the study:

Houses with trees on the west side of their home had a “much lower power bill”.

Older homes had the most shade coverage, because people did not use to rely on air conditioning as much to keep them cool.

Children under age 12 consume the most power in a home as they watch television, play games and frequently leave lights on.

Fall and early winter are the perfect seasons to plant a tree. This time of year many nurseries（苗圃）are trying to reduce their inventory of trees heading into the winter, so you may find a deal on trees easily to plant around your lot.

While you have the spade out, consider planting a tree near your outside air conditioning unit. The shade will keep the unit cooler and help it operate more efficiently. Be sure to plant far enough from the unit to allow proper airflow, and account for the tree’s growth over time.

It actually hurts to watch the trees being knocked over when land developers plan neighborhoods because trees could provide much needed shade to new homeowners, reducing their electric bill and the amount of energy they consume. Hopefully this study, and more like it in the future, will encourage developers and builders to plan around trees as much as possible to offer homeowners a shaded lot.
