名詞的數:
重點應了解和掌握以下內容:
1、名詞的可數和不可數:
與漢語不同,英語中名詞要區(qū)分可數與不可數。
籠統(tǒng)地講,物質名詞,如:water(水), iron(鐵), wood(木頭)等, 和抽象名詞,如:democracy(民主), freedom(自由), happiness(幸福)等為不可數。
不可數名詞前不能加a (an),后面不能加s (es),這是考試中對此類題目判斷的重要依據。
2、以下名詞為不可數名詞:
news(消息) information(信息)
furniture (家具) equipment(設備)
advice (勸告) weather(天氣)
work*(工作) clothing(衣服)
baggage(行李)
work作 "工作" 解釋時為不可數名詞,"找工作"不能說to find a work, 應為to find a job; work作"著作"、"作品"解時是可數名詞,如:Deng Xiaopin's works (鄧小平著作)/ a work about Deng Xiaopin (一件關于鄧小平的作品);作 "工廠" 解釋時,單復數同形:a steel works (一個鋼鐵廠) / two chemical works(兩家化工廠)
實例:
We have a large staff but there ______ in the office.
A. haven't many furnitures
B. aren't many furnitures
C. hasn't much furniture
D. isn't enough furniture
解題思路:根據名詞數的概念A、B肯定錯,不必考慮;C、D的主要差異是"hasn't"與 "isn't", 句子中有there,說明該句是there be句型,故正確答案為D.題中staff, office 等詞與解題無關。
注意辨別句子中斜體詞的數及其意義:
There is still much room for improvement. (仍有許多改進的余地)
He has published two important papers on this subject. (他在這個課題上已發(fā)表了兩篇重要論文。)
