字號(hào):

10.Our space and time laws don't seem to apply to objects in the area of a black hole.
    我們的時(shí)空法則似乎不適用于黑洞區(qū)內(nèi)的物體。(介詞短語作定語)
    11.We do not yet…relativity theory; but it is…for their existence.
    yet: still
    此句中的it為形式主語,實(shí)際主語為that引導(dǎo)的主語從句
    before引導(dǎo)時(shí)間狀語從句
    12.It is only recently that astronomers have begun specific research into black holes.

    13.a satellite was launched to gather data about the 10 million black holes which are thought to be in the Milky Way. (about引導(dǎo)的介詞短語作定語修飾data)
    which 引導(dǎo)定語從句修飾 holes
    data 的單數(shù)為datum
    14.Exploding 和believed to be black holes 均為分詞作定語,修飾stars
    The most convincing evidence of black holes comes from research into binary star systems. Binary stars, as their name suggests, are twin stars whose position in space affects each other. In some binary systems, astronomers have shown that there is an invisible companion star, a “partner” to the one which we can see in the sky. Matter from the one which we can see is being pulled towards the companion star. Could this invisible star, which exerts such a great force, be a black hole? Astronomers have evidence of a few other stars too, which might have black holes as companions.
    Para.4
    15.The most…affects each other.
    as 的用法,引導(dǎo)非限定性定語從句。修飾Binary stars “雙星系”
    whose 引導(dǎo)定語從句修飾 twin stars
    16.下面的幾句話中的which 用作定語從句的引導(dǎo)詞,可用于限制性定語從句,也可用于引導(dǎo)非限制性定語從句。that 則不可用于引導(dǎo)非限制性定語從句。
    The story of black holes is just beginning. Speculations about them are endless. There might be a massive black hole at the center of our galaxy swallowing up stars at a very rapid rate. Mankind may one day meet this fate. On the other hand, scientists have suggested that very advanced technology could one day make use of the energy of black holes for mankind. These speculations sound like science fiction. But the theory of black holes in space is accepted by many serious scientists and astronomers. They show us a world which operates in a totally different way from our own and they question our most basic experience of space and time.
    第三部分
    Para.5
    17 There might be…a very rapid rate.
    swallowing up stars at a very rapid rate是現(xiàn)在分詞短語作定語,修飾hole
    at the center of our galaxy 是狀語
    story 比較真實(shí)的故事
    fiction 不太真實(shí)的故事同義詞:novel

    重點(diǎn)句:
    1.Well, it's difficult to answer this question, since the terms we would normally use to describe a scientific phenomenon are inadequate here. (第一段)
    2.Astronomers and scientists think that a black hole is a region of space (not a thing ) into which matter has fallen and from which nothing can escape - not even light. So we can't see a black hole. (第一段)
    3.The theory is that some stars explode when their density increases to a particular point; they collapse and sometimes a supernova occurs. (第二段)
    4.Some people think that the Star of Bethlehem could have been a supernova. (第二段)
    5.The collapse of a star may produce a White Dwarf or a neutron star - a star, whose matter is so dense that it continually shrinks by the force of its own gravity. (第二段)
    6.Imagine the earth reduced to the size of a marble, but still having the same mass and a stronger gravitational pull, and you have some idea of the force of a black hole. (第二段)
    7.For example, if a man fell into a black hole, he would think that he reached the center of it very quickly. (第三段)
