B. is leaving; is taking off

C. am leaving; takes off

D. leave; is taking off

C

【解析】

试题分析:句意:几天后,我将要去北京。你知道最早的飞机什么时候起飞?在英语中,一般现在时和现在进行时都可表示按计划、安排将要发生的动作,但是在这一用法上,两者的含义有所不同。一般现在时表示按计划、安排的将来动作是不可改变的;而现在进行时表示按计划、安排的动作则在含义上较为灵活。用于一般现在时和现在进行时表示将来的动词一般为动态动词,动态动词中尤以begin, come, go, leave, sail, start, arrive, return等最为常见。题干中“我几天后将离开上海”是一个主观愿望,可以有所改变;而“最早的飞机的起飞时间”是不能随意变更的。所以第一空用进行时态,第二空用一般现在时,但都表示将来。故C项为最佳答案。

考点:考查将来时的不同表达法。

Deserts are found where there is little rainfall or where rain for a whole year falls in only a few weeks' time. Ten inches of rain may be enough for many plants to survive if the rain is spread throughout the year. If it falls, within one or two months and the rest of the year is dry, those plants may die and a desert may form.

Sand begins as tiny pieces of rock that get smaller and smaller as wind and weather wear them down. Sand dunes (沙丘) are formed as winds move the sand across the desert. Bit by bit, the dunes grow over the years, always moving with the winds and changing the shape. Most of them are only a few feet tall, but they can grow to be several hundred feet high.

There is, however, much more to a desert than sand. In the deserts of the southwestern United States, cliffs (悬崖) and deep valleys were formed from thick mud that once lay beneath a sea more than millions of years ago. Over the centuries, the water dried up. Wind, sand, rain, heat and cold all wore away at the remaining rocks. The faces of the desert, mountains are always changing—very, very slowly —as these forces of nature continue to

work on the rock.

Most deserts have a surprising variety of life. There are plants, animals and insects that have adapted to life in the desert. During the heat of the day, a visitor may see very few signs of living things, but as the air begins to cool in the evening, the desert comes to life. As the sun begins to rise again in the sky, the desert once again becomes quiet and lonely.
