The difference between a liquid and a gas is obvious【C1】______the conditions of temperature and pressure commonly found【C2】______of the Earth. A liquid can be kept in an open container and【C3】______it to the level of a free surface. A gas forms no free surface but【C4】______to diffuse throughout the space available; it must【C5】______be kept in a closed container, as【C6】______a planet’s atmosphere. The distinction was a【C7】______feature of early theories【C8】______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【C9】______different kinds of molecules(分子). The theories now prevailing【C10】______a quite different approach by emphasizing.【C11】______liquids and gases have in common. They are both forms of matter that have no permanent structure, and they both【C12】______easily. They are fluids.
The【C13】______similarity of liquids and gases becomes clearly apparent when the temperature and pressure are raised somewhat.【C14】______a closed container partially filled with a liquid is heated. The liquid expands, or【C15】______, becomes less dense; some of it evaporates.【C16】______, the vapor above the liquid surface becomes denser as the evaporated molecules are【C17】______it. The combination of temperature and pressure【C18】______the densities become equal is【C19】______the critical point. Above the critical point the liquid and the gas can no longer be【C20】______; there is a single, undifferentiated fluid phase of uniform density. [br] 【C3】
选项
A、fills
B、be filled
C、filling
D、to fill
答案
A
解析
考查句子层面动词的使用。这是一个由and连接的并列句,缺少与can be形成并列关系的谓语,因此A为正确选项,fill一词具有使动含义,表示“使……充满容器”。因空格后面有代词让指代container(容器),作fill的宾语,因此不能用被动式,选项B不正确。选项C和D都为非谓语形式,故不正确。
