阅读下文,完成下列小题。

最美的景色是心情

    那日和友人一块去庐山游玩。庐山有一景点名曰三叠泉。那是庐山胜景之一。当地人有言:不到三叠泉,枉为庐山客。可见是极有看头了。

    几个人结伴由导游领着从五老峰下来。那导游先生坐在一凉亭处便不肯走了,说,去三叠泉来回十四华里,只有一条山道可走。想看三叠泉,要再登四千级台阶。然后挥挥手:你们去吧。

    我当时就傻眼了:四千级台阶!刚才爬了一趟五老峰力气已快消耗尽了,再爬四千级台阶?

    我仰天长叹,脸上显出无力回天的神情。友人却不管,径自往前赶了。

    我一个人孤零零落在了后头。

    独自歇歇停停地走着。却发现去往三叠泉路上的景色十分的秀美。极目远眺,茫茫云海疏淡出山的轮廓,宛若瑶池仙境。近处青山如黛,绿树成阴。人在山谷里走着,早把一个夏天抛在了脑后。只当是走进了一个清凉幽静的世界。特别是山涧里哗哗作响的流泉,迂回曲折地从一块块突兀迭起形态各异的山石间流过,时而安详,时而暴戾,时而如暖流涌动,时而如决堤狂潮,让你不得不为大自然的奇美造化惊叹不已,驻足流连。

    我真是沉醉其间,乐而忘返了。心里哪还有什么三叠泉。

    独坐在山石上,我查以悠闲成山;涉足于清涧中,我可以明丽如水;牵一片白云走动,我便是天上的仙人,这才是旅游的心情呵!这旅游的兴致,哪里用得着刻意去装出来?!

    突然觉得,游山戏水者若是你的心沉醉其中,那真是应了那句“一花一世界,一鸟一天堂”。明明置身山水之中,怎可只有三叠泉才让你陶醉?

    一片云在飘。有人说是风动,有人说是云动。其实那是你的心在动。

    最美的景色是人的心情呵!

    坐在一块状如卧龟的石头上小憩。头上是触手可及的天,前方是聚聚散散的云,两边兀立的是青山,拂面而过的是清风,耳边轰然作响的是流泉。这等景致你说应该叫什么呢?如果愿意,可不可以把它叫做“戏水崖”?

    这样想着,我的心就如三月里翩跹的彩蝶了。再看那些行色匆匆忙着去看三叠泉的旅客,心里就不免生出几分感慨:身边这么好的景色顾不得欣赏,却疲于奔命般认定一个三叠泉——旅游难道是在履行一种职责吗?

    接近黄昏时分,我的那些朋友满脸倦容回来了。一个个累得东倒西歪,连说话的力气也没有了。哪里还找得出旅游的那份浪漫和闲适?这时我便知道了:与我的朋友相比,我少看了一个三叠泉,但留在我心里的那个秀美的庐山却是完整的了。

    About 7 million people over the age of 65 have been diagnosed with depression, and many more could be suffering. It is high time that you learned how to know the signs and help them. Depression is a big problem for seniors, especially those who are lack of care and attention. Older people are much more likely to be alone, socially isolated(孤立的) or feel a lack of purpose. Sometimes older people have a much more difficulty time admitting mental health problems. Many times, the link between depression and physical illness is much stronger.

    The elderly don't like to express sadness the way that young people do. Older people who are depressed may have more physical troubles and may pay more attention to them. Depression may result from early memory loss and meanwhile, depression will make a person forget more and faster. A patient with early memory loss and depression really needs to be treated for the depression to slow the memory loss. A mood change is also a sign of depression. If a previously calm person becomes increasingly annoyed, or a previously clean person no longer bothers to shower or clean up, that person should be considered.

    Don't tell older adults that you think they may be depressed, as older adults --- particularly men–see depression as a weakness. What you should do is tell them you're worried about their health. Tell them they seem to be out of sorts.

    Say you just want to check with the doctor to see what's going on. Once you've used physical symptoms to get that person to agree to a check-up, mention your fear to the doctor and allow the doctor to approach the subject of depression with the patient.
