阅读下面文字,按要求答题。

  我们还可以根据云上的光彩现象,推测天气的情况。(在太阳和月亮的周围,有时会出现一种美丽的 * * 光圈,里层是红色的,外层是紫色的。)这种光圈叫做晕。日晕和月晕常常产生在卷层云上,卷层云后面的大片高层云和雨层云,是大风雨的征兆。所以有“日晕三更雨,月晕午时风”的说法。说明出现卷层云,并且伴有晕,天气就会变坏。另有一种比晕小的彩色光环,叫做“华”。颜色的排列是里紫外红,跟晕刚好相反。日华和月华大多产生在高积云的边缘部分。华环由小变大,天气趋向晴好。华环由大变小,天气可能转为阴雨。夏天,雨过天晴,太阳对面的云幕上,常会挂上一条彩色的圆弧,这就是虹。人们常说:“东虹轰隆西虹雨。”意思是说,虹在东方,就有雷无雨;虹在西方,将有大雨。还有一种云彩常出现在清晨或傍晚。太阳照到天空,使云层变成红色,这种云彩叫做霞。朝霞在西,表明阴雨天气在向我们进袭;晚霞在东,表示最近几天里天气晴朗。所以有“_______________,______________________”的谚语。

1、这个语段阐释了什么事理?

________________________________________________

2、上文在说明每种光彩及与天气的关系时都采用了什么说明顺序?___________

3、这个语段突出的特点是用了引用谚语的说明方法,说说采用这种方法的好处?

________________________________________________

4、在句中的横线上填上一句谚语。

Father Christmas is at risk of serious illness because of his bulging waistline and needs to cut down on the mince pies, doctors warned.

A survey of shopping centre Santas in Scotland revealed an average waist size of 47 inches - seven inches more than is considered safe.

Dr Miles Fisher, consultant physician at Glasgow Royal Infirmary said: "The image of Santa is of a round, jolly person but if you have obesity around your tummy, then it is very bad for you.

"Before, we thought it was just not good to be overweight but now we know that having fat around your middle is particularly bad.

"That fat produces hormones, which have been associated with heart disease and other conditions."

According to health guidelines, having a waist circumference of more than 40 inches for men or 35 inches for women is a key indicator of abdominal obesity.

It is associated with a greater risk of heart disease or type 2 diabetes. And people who have rounder stomachs, known as "central obesity", are more at risk than people who are merely overweight.

Perhaps Santa should consider cutting back on the sherry as well.
