1. We have to pay attention due to the possibility of a serious water shortage. 请问 the possibility 和 a serious water shortage 的冠词为何分别是the 与a?
2. 我们可以说 compose poems, 但是可以说 compose work 和 compose paper 吗?compose是否只能接具体的实物,是吗?
shortage 是个“可变名词”(既可数,又不可数),当“缺乏”这个概念被具体化时,也就是前面有形容词修饰的时候,往往用作可数名词,所以加冠词a。注意:a 跟water无关,water 也是修饰shortage 作定语。
the possibility 在这里是特指,被后面的of a serious water shortage 将它限定,所以,应加定冠词。
compose,表示“(文学、音乐、绘画等作品的)创作”,《柯林斯词典》的解释是:
1. When someone composes a piece of music, they write music.
2. If you compose something such as a letter, poem, or speech, you write it, often using a lot of concentration or skill.
所以可以说:
compose a piece of music/a letter/a poem/a speech/a paper(论文)...
【注】compose 是比较正式的说法,往往需要用心和技巧,我们通常用write 代替。
