　　①也许，一切的一切，盖源于那个绿色的梦。

　　②也许，只有那个绿色的梦，才深深地、深深地植埋于地下。

　　③梦想着荒漠里腾起绿云，梦想着绿云里闪出妩媚的花朵，梦想着花朵能邀来洁白的小鸟，梦想着小鸟能衔来蓝色的河流和绿色的草地，梦想着蓝的河流奔涌着不息的生命之歌，绿的草地生长着不败的爱情之果……

　　④于是，深深地、深深地植埋于地下，深深地、深深地饮着这份永无尽头的黑色寂寞。

　　⑤这是一种难以忍受的黑色寂寞！

　　⑥没有言语，没有阳光，没有欢呼，千年万年，有的只是一种强烈的生存欲望和绿的梦想。

　　⑦缄默是唯一的语言。也许，唯有缄默才能真正表达万语千言也难以表述的丰蕴内涵。缄默也是一种灵魂的独白。在无月的黑夜，假如你悉心谛听，黝黑而神秘的森林里有一颗热情的灵魂在痛苦地呻吟或欢乐地喊叫。

　　⑧有什么比家雀和秋蝉更乐于絮絮叨叨的呢？就成全它们吧！让它们一千遍一万遍尽情地陈述着肤浅的生命感悟吧！根无须表白，根永远默默无语，用生命的伟大为人类撑起一片绿阴。

　　⑨缄默，才有力量倔犟地延伸。

　　⑩每天每天，都是一场无言的抗争，与坚硬的地壳，与冰冷的岩层，与灼人的干渴或泛滥的洪涝。根痛苦地扭曲着身体，探寻着点点沃土，吸吮着滴滴甘露。千年万年，生生不息，于是才有了这宇宙的伟大奇迹：树木——树林——森林…一

　　把绿的荣耀托给森林，把关的微笑交给花朵，把爱的温柔送给草地，把生命的歌声让给长流不息的江河。却把苦难和寂寞永远地、永远地留给自己。在深深的、深深的地下，永远地、永远地生活着盘错着虬曲着一个可歌可泣的根之家族！

　　也许，会有风暴，但风暴只能摧折地上的茎，却不能摧毁地下深植的根；或许，会有野火，但野火只能将大地化为焦土，却不能烧掉根的绿色的梦想。而风暴和野火过后，漫山遍野照旧奔涌出那神奇的绿。

If it really is what’s on the inside that counts, then a lot of thin people might be in trouble.

Some doctors now think that the internal(内部的) fat surrounding important organs like the heart or liver could be as dangerous as the external fat which can be noticed more easily.

“Being thin doesn’t surely mean you are not fat,” said Dr Jimmy Bell at Imperial College. Since 1994, Bell and his team have scanned nearly 800 people with MRI machines to create “fat maps” showing where people store fat.

According to the result, people who keep their weight through diet rather than exercise are likely to have major deposits of internal fat, even if they are slim.

Even people with normal Body Mass Index scores can have surprising levels of fat deposits inside. Of the women, as many as 45 percent of those with normal BMI scores (20 to 25) actually had too high levels of internal fat. Among men, the percentage was nearly 60 percent.

According to Bell, people who are fat on the inside are actually on the edge of being fat. They eat too many fatty and sugary foods, but they are not eating enough to be fat. Scientists believe we naturally store fat around the belly first, but at some point, the body may start storing it elsewhere.

Doctors are unsure about the exact dangers of internal fat, but some think it has something to do with heart disease and diabetes. They want to prove that internal fat damages the body’s communication systems.

The good news is that internal fat can be easily burned off through exercise or even by improving your diet. “If you want to be healthy, there is no short cut. Exercise has to be an important part of your lifestyle,” Bell said.
