    问答题
    The difference between a liquid and a gas is obvious (1)____ the conditions of temperature and pressure commonly found at the surface of the Earth. A liquid can be kept in an open container and fills it to the level of a free surface. A gas forms no free surface but tends to diffuse throughout the space available; it must (2)____ be kept in a closed container, as in the (3)____ of a planet’s atmosphere. The distinction was a prominent feature of early theories (4)____(describe) the phases of matter. In the nineteenth century, for example, one theory maintained that a liquid could be “dissolved” in a vapor without losing its identity, and another theory held that the two phases are made up of different kinds of molecules (分子). The theories now prevailing (5) t____ a quite different approach by emphasizing what liquids and gases have in common. They are both forms of matter (6)____ have no permanent structure, and they both flow easily. They are fluids.The (7)____(fundament) similarity of liquids and gases becomes clearly apparent when the temperature and pressure are raised somewhat. Suppose a closed container partially filled with a liquid is heated. The liquid expands, or in other (8)____, becomes less dense; some of it evaporates. In contrast, the vapor above the liquid surface becomes dense as the evaporated molecules are added to it. The combination of temperature and pressure (9)____ which the densities become equal is called the critical point. Above the critical point the liquid and the gas can no longer be (10)____(distinguish); there is a single, undifferentiated fluid phase of uniform density.

    1.on 根据后面的the conditions of可知此处填on。on the conditions of在…条件下。
    2.therefore 这里表因果关系,所以用therefore。句意:气体容易扩散,所以必须保存在密闭的容器里。
    3.case in the case of在…的情况下,就…而言。根据上下文,这里是说“必须将气体存放在一个密封的容器里,如同一颗行星的大气一样。”
    4.describing 本句中的describe的逻辑主语为theories,故应用现在分词。同时,describe这一动作只说明一种事实,并不与其他动词作时间上的先后比较,不必用完成时。
    5.take take approach采用…方法,符合句意。
    6.that that引导定语从句,修饰forms of matter。
    7.fundamental 句意:液体与气体之间的根本相似性在温度和压强有所提高时变得十分明显。
    8.words in other words换句话说。
    9.at 句意:使液体和气体密度相同的那个状态下的温度和压力被称作临界点。句中的temperature and pressure是先行词,需要一个关系词引导一个定语从句修饰先行词。特定数值的temperature和pressure与at搭配,意为“在某个温度和压力下”。
    10.distinguished 句意:在临界点之上时,气体和液体就很难再区分开来。
