Giải thích:
inefficiency (n): sự không hiệu quả
inefficient (adj): không hiệu quả
Dấu hiệu: vì trước là trạng từ “simply” (một cách đơn giản) nên vị trí sau nó phải là một tính từ.
Hoặc: adj + or + adj => sau “or” trong trường hợp này phải điền adj.
Sửa: inefficiency => inefficient
Tạm dịch: Quảng cáo đại chúng được sử dụng khi việc bán hàng giữa người với người là không thể thực hiện được hoặc đơn giản là không hiệu quả.
Chọn C.
Read the following passage and mark the letter A, B, C or D on you answer sheet to indicate the correct answer to each of the questions.
Glaciers are large masses of ice on land that show evidence of past or present movement. They grow by the gradual transformation of snow into glacier ice. A fresh snowfall is a fluffy mass of loosely packed snowflakes, small delicate ice crystals grown in the atmosphere. As the snow ages on the ground for weeks or months, the crystals shrink and become more compact to form firm, a much whole mass becomes squeezed together into a more dense form, granular snow. As new snow falls and buries the older snow, the layers of granular snow further compact to form firm, a much denser kind of snow, usually a year or more old, which has little pore space. Further burial and slow cementation- a process by which crystals become bound together in a mosaic of intergrown ice crystals- finally produce solid glacial ice. In this process of recrystallization, the growth of new crystals at the expense of old ones, the percentage of air is reduced from about 90 percent for snowflakes to less than 20 percent for glacier ice. The whole process may take as little as a few years, but more likely ten or twenty years or longer. The snow is usually many meters deep by the time the lower layers are converted into ice.
In cold glaciers those formed in the coldest regions of the Earth, the entire mass of ice is at temperatures below the melting point and no free water exists. In temperate glaciers, the ice is at the melting point at every pressure level within the glaciers, and free water is present as small drops or as larger accumulations, in tunnels within or beneath the ice. Formation of a glacier is complete when ice has accumulated to a thickness (and thus weight) sufficient to make it move slowly under pressure, in much the same way that solid rock deep within the Earth can change shape without breaking. Once that point is reached, the ice flows downhill, either as a tongue of ice filling a valley or as thick ice cap that flows out in directions from the highest central area where the most snow accumulates. The up down leads to the eventual melting of ice.
