银河系的英文介绍
The Milky Way is the galaxy which is the home of our Solar System together with at least 200 billion other stars (more recent estimates have given numbers around 400 billion) and their planets, and thousands of clusters and nebulae, including at least almost all objects of Messier's catalog which are not galaxies on their own (one might consider two globular clusters as possible exceptions, as probably they are just being, or have recently been, incorporated or imported into our Galaxy from dwarf galaxies which are currently in close encounters with the Milky Way: M54 from SagDEG, and possibly M79 from the Canis Major Dwarf). See our Messier Objects in the Milky Way page, where details are given for each object to which part of our Galaxy it is related. All the objects in the Milky Way Galaxy orbit their common center of mass, called the Galactic Center (see below).

As a galaxy, the Milky Way is actually a giant, as its mass is probably between 750 billion and one trillion solar masses, and its diameter is about 100,000 light years. Radio astronomial investigations of the distribution of hydrogen clouds have revealed that the Milky Way is a spiral galaxy of Hubble type Sb or Sc. Therefore, our galaxy has both a pronounced disk component exhibiting a spiral structure, and a prominent nuclear reagion which is part of a notable bulge/halo component. Decade-long observations have brought up more and more evidence that the Milky Way may also have a bar structure (so that it would be type SB), so that it may look like M61 or M83, and is perhaps best classified as SABbc. Recent investigations have brought up support for the assumption that the Milky Way may even have a pronounced central bar like barred spiral galaxies M58, M91, M95, or M109, and thus be of Hubble type SBb or SBc.
More on the structure of the Milky Way
The Milky Way Galaxy belongs to the Local Group, a **aller group of 3 large and over 30 **all galaxies, and is the second largest (after the Andromeda Galaxy M31) but perhaps the most massive member of this group. M31, at about 2.9 million light years, is the nearest large galaxy, but a number of faint galaxies are much closer: Many of the dwarf Local Group members are satellites or companions of the Milky Way. The two closest neighbors, both already mentioned, have only recently been discovered: The nearest of all, discovered in 2003, is an already almost disrupted dwarf galaxy, the Canis Major Dwarf, the nucleus of which is about 25,000 light-years away from us and about 45,000 light-years from the Galactic Center. Second comes SagDEG at about 88,000 light years from us and some 50,000 light years from the Galactic Center. These two dwarfs are currently in close encounters with our Galaxy and in sections of their orbits situated well within the volume ocupied by our Milky Way. They are followed in distance by the more conspicuous Large and Small Magellanic Cloud, at 179,000 and 210,000 light years, respectively.
The spiral arms of our Milky Way contain interstellar matter, diffuse nebulae, and young stars and open star clusters emerging from this matter. On the other hand, the bulge component consists of old stars and contains the globular star clusters; our galaxy has probably about 200 globulars, of which we know about 150. These globular clusters are strongly concentrated toward the Galactic Center: From their apparent distribution in the sky, Harlow Shapley has concluded that this center of the Milky Way lies at a considerable distance (which he overestimated by factors) in the direction of Sagittarius and not rather close to us, as had been thought previously.
Our solar system is thus situated within the outer regions of this galaxy, well within the disk and only about 20 light years "above" the equatorial symmetry plane (to the direction of the Galactic North Pole, see below), but about 28,000 light years from the Galactic Center. Therefore, the Milky Way shows up as luminous band spanning all around the sky along this symmetry plane, which is also called the "Galactic Equator". Its center lies in the direction of the constellation Sagittarius, but very close to the border of both neighbor constellations Scorpius and Ophiuchus. The distance of 28,000 light years has recently (1997) been confirmed by the data of ESA's astrometric satellite Hipparcos. Other investigations published consequently have disputed this value and propose a **aller value of some 25,000 light years, based on stellar dynamics; a recent investigation (McNamara et.al 2000, based on RR Lyrae variables) yields roughly 26,000 light years. These data, if of significance, wouldn't immediately effect values for distances of particular objects in the Milky Way or beyond.
The solar system is situated within a **aller spiral arm, called the Local or Orion Arm, which is merely connection between the inner and outer next more massive arms, the Sagittarius Arm and the Perseus Arm; see our Milky Way Spiral Structure page.
Similar to other galaxies, there occur supernovae in the Milky Way at irregular intervals of time. If they are not too heavily obscurred by interstellar matter, they can be, and have been seen as spectacular events from Earth. Unfortunately, none has yet appeared since the invention of the telescope (the last well observed supernova was studied by Johannes Kepler in 1604).
Milky Way pictures are wide-field exposures. Besides being attractive and often colorful, they are often suited to view the Milky Way objects (including nebulae and star clusters) in their celestial surroundings of field stars. Some fields include lots of Messier objects and thus included here:

In order to obtain a picture of the whole Milky Way as it appears from Earth, one must either compose a mosaic of many photographs (optionally computer-processed), or create a drawing; fine examples may be accessed below:

In the infrared light, the structure of the Milky Way can be better investigated, as the obscurring dust clouds are of better transparency for long wavelength IR than for the visible light. The Cobe satellite has provided an infrared image of the Milky Way's central region.
The central region of the Milky Way, as those of many other galaxies, is more densely crouded with stars than the outer region, and contains a massive central object, Sagittarius A*.
Below we give some data for the Galactic Center (this and all following positions for epoch 2000.0):
Right ascension 17 : 45.6 (h : m)
Declination -28 : 56 (deg : m)
Distance 28 (kly)
The Galactic North Pole is at
Right ascension 12 : 51.4 (h : m)
Declination +27 : 07 (deg : m)
The coordinate data given here were extracted from the online coordinate calculator at Nasa/IPAC's Extragalactical Database (NED) (also available by telnet).
Our Sun, together with the whole Solar System, is orbiting the Galactic Center at the distance given, on a nearly circular orbit. We are moving at about 250 km/sec, and need about 220 million years to complete one orbit (so the Solar System has orbited the Galactic Center about 20 to 21 times since its formation about 4.6 billion years ago).
In addition to the overall Galactic Rotation, the solar system is moving between the neighboring stars (peculiar motion) at a velocity of about 20 km/s, to a direction called "Solar Apex," at the approximate position RA=18:01, Dec=+26 (2000.0); this motion has been discovered by William Herschel in 1783.
Considering the sense of rotation, the Galaxy, at the Sun's position, is rotating toward the direction of Right Ascension 21:12.0, Declination +48:19. This shows that it rotates "backward" in the Galactic coordinate system, i.e. the Galactic North Pole is actually a physical South Pole with respect to galactic rotation (defined by the direction of the angular momentum vector).

乃琳tom是什么梗?
这个梗是指乃琳喜欢tom。梗,网络用语,常出现在综艺节目及网络中。所谓“梗宴灶”的意思是笑点,铺梗就是为笑点做铺垫,系对“哏”字的误用。
一般来说,梗用于流行事物比如综艺、动画剧、动画电影、真人剧、真人电影、漫画 小说、电子游戏等。“梗”字的词义被不断扩大引申,大到某个时间段,小到情节插曲,乃至故事中发生的片段都可以叫“梗”,比如“身高梗”、“经典梗”、“撞脸虚祥知梗”、“言情梗”、“创意梗”、“幽默梗”等。
中国西部人,如山西、甘肃、宁夏等地语言中没有前鼻音,把人、盆、贫等字读成仍、朋差消、平,因此他们读哏为梗,说的多了,传到网络上,就成了梗。

一英语的学习方法
(1)语言的学习是培养一种感觉,而感觉要靠数量的积累来培养。俗话说水到渠成。同样的道理,达到了一定的量,"语感"就产生了。这时应再把感觉上升到理念,将理念融入到自己的思维中,英语就能运用自如。请注意量的积累在基础阶段最为重要。
(2)你可以回忆一下你学习任何一种技能的过程。无论是游泳还是骑自行车,都是重复同一类动作的过程。 任何技能的获得,当然包括英语这项语言技能,均来自重复。
二如何学习英语
(1)首先是语音部贺歼分,分为21个元音、19个辅音,学会之后再学习拼读,一定要多加练习,然后再学习语音篇,这样基本上遇见的英语你族差都会读了。语法的学习是很有必要的,英语是主宾谓结构,其中还有时态,例如:过去时态、将来时态等等,都是需要掌握的。
(2)词汇的积累,无论是学习什么语言都需要一定的词汇积累,就像我们学习韩语一样,上学的时候还要每天都背单词。然后根据之前学的语音去练习词汇的读音。
