2. He fell down to the ground, his mouth ________ and eyes ________. A. open; close B. opened; closed C. opened; close D. open; closed D 此题很容易误选A，其实应选 D。open 和 close 均可用作动词，前者表示“开”，后者表示“关”，是一对反义词，如：Please open your mouth.(请张开嘴)，Please close your mouth. (请闭上嘴)。但是 open 和 close 也可用作形容词，此时前者意为“开着的”，后者意为“接近的”、“亲近的”等，而并不表示“关着的”，要表示“关着的”，英语用 closed，即用作形容词时，open 与close 不是一对反义词，而与 closed 才是反义词。 3. Professor White has written some short stories, but he is ________ known for his plays. A. the best B. more C. better D. the most C 此题首先不宜选B或D，因为 well known 的比较级和最高级通常是 better known和best known，有时也可以是 more wellknown 和 most wellknown，但通常不能是 more known 和 most known。至于是选A还是C？这就要看语境。由于A和C的区别是比较级和最高级的区别，所以区分这两个答案的关键就是要分清句中涉及的是两者比较，还是三者或三者以上的比较。细读全句，我们发现句中涉及的只有 stories 和 plays 这两者，所以应选C为最佳。 Module2 Unit 1 Wish you were here（2） 形容词和副词 形容词是用来修饰名词或代词，表示人或事物的性质、状态和特征的词。形容词通常作定语，表语，主补，宾补和状语。修饰动词，表示动作发生的时间、地点、方式、程度等或表达状态的词叫副词。副词常见类别有： 1．时间副词：常见的有now, then, soon, ago, recently, lately, later, before, early, today, tomorrow, yesterday, tonight, suddenly, immediately, still, already, just等。 2．地点副词：常见的有here, there, up, down, away, nearby, home, ahead, abroad, indoors, overseas, upstairs, downstairs等。 3．方式副词：表示行为方式的副词大多以ly结尾，常见的有quietly, heavily, warmly, carefully, happily, politely, angrily等。 4．频度副词：常见的有always, usually, often, frequently, constantly, occasionally, sometimes, seldom, hardly, rarely, never等。 |
