they are also much more. Meteors, or "shooting s |

Explanation: If the Moon's apparent diameter is not quite large enough to cover the Sun
during a solar eclipse, an annular eclipse can be the result -- a spectacle of silhouetted Moon
surrounded by a solar "ring of fire". Just such a view was possible for observers in the far
northern hemisphere as the new Moon slid across the solar disk on May 31st. Still, for
astronomical adventurers at Cape Wrath on the north |

Explanation: Parts of Saturday's (March 3) lunar eclipse will be widely
visible. For example, skywatchers in Europe, Africa, and western Asia will
be able to see the entire spectacle of the Moon gliding through Earth's
shadow, but in eastern North America the Moon will rise already in its total
eclipse phase. Of course if you traveled to the Moon's near side, you could

A theorem (IPA pronunciation: ['θɪəɹəm], from vulgar

is a proposition that has been or is to be proved on the basis of explicit
assumptions. Proving theorems is a central activity of mathematicians. Note
that "theorem" is distinct from "theory".
A key property of theorems is that they possess proofs, not merely that they

Partial Eclipse over North America
In the U.S., more than half the Sun’s surface will be covered southwest of
a line from Texas to northern California. But this occurs very late on Monday
afternoon — too late to dim the landscape abnormally. Keep in mind that the
Sun is no less dangerous to look at during a partial eclipse than it is on a
normal sunny day. Unless the Sun is very low and appears dull red, don't be

QINGDAO, China, July 25 - Zong Zhizhong peered from behind his blue wraparound

太平洋鹦鹉的英文名字是Pacific Parrotlet,原产于秘鲁和厄瓜多尔的西部、安第斯山
脉和太平洋之间的狭长地区,因太平洋而得名,生活的自然环境是热带、亚热带干燥林
地。太平洋鹦鹉是美洲大陆最小的鹦鹉之一,还是常见宠物鹦鹉中最小的,体长十三厘
米,体重二十五克。从我有限的经验看,太平洋鹦鹉是最有趣的宠物鹦鹉之一,同时又
是物质方面要求最低、最容易养的,我写一个简单介绍,向喜欢鹦鹉的人推荐一下。
一只摄于秘鲁野外的雄性太平洋鹦鹉,非常有气场。
一对太平洋鹦鹉,左边的是雌性的,右边的是雄性的,注意眼睛后面的蓝色。
外观
太平洋鹦鹉的颜色有很多,有野生的原色,也有人工培养的变色,配上玲珑的身材和跳
动不停的身姿,可说是赏心悦目。野生的太平洋鹦鹉羽毛以绿色为主,雌鸟和雄鸟羽毛
有显著区别,雌鸟通体绿色,不同部位的绿色有深浅之别,雄鸟身上大部分是绿色和灰
绿色,在翅膀的飞羽上和背的下半部是蓝色,眼睛后面有一条蓝色条纹,因此性别一眼
就能看出来。太平洋鹦鹉的人工繁殖在北美好像有八十年了,在欧洲可能更长,现在有

1 大熊猫(Giant panda)
大熊猫是特产于中国的珍稀动物。大熊猫有两个亚种:分布于四川省及甘肃省山地的指
名亚种,和分布于陕西省的秦岭亚种。任何人仅凭外形——它们圆滚滚的身体,黑白分
明的颜色——就可以轻易的认出大熊猫。憨态可掬的外表,和特殊的分类与保护地位,
让大熊猫名声大噪,在世界各国眼中几乎成了中国的代名词,其形象也登上了世界自然
基金会的logo。
大熊猫的分类地位,曾在历史上众说纷纭。有主张划归猫科或者浣熊科的,有主张和小
熊猫一起划归熊猫科的,也有主张单独为一科的。但很多这类主张缺少证据支持:比如
大熊猫和小熊猫都多出来的一“指”,仅仅是因为食性相同造成的趋同进化,并没有分
类学意义。现代分子生物学研究表明,大熊猫应该被划归熊科。换句话说,大熊猫的的
确确是一种熊!也许,“猫熊”的称呼更合适些吧。当然,大熊猫和其他熊类的分化时
间非常早,是熊科中最原初的支系,无怪乎被称作动物界的“活化石”呢。
