做好英语单项选择题的方法

做好单项选择题的九种方法 1. 排除法 当你对A、B、C、D四个答案都感到似是而非,不能选出正确答案时,就要采取“逐个排除”的方法,经过分析,把没有被排除的答案定为正确答案,这类试题以涉及词汇知识的试题居多。 ◎He does his homework much ____ than he did two years ago. A. careful B. more careful C. carefully D. more carefully 【分析】空白处于主句的状语位置,只能修饰动词does,又因为后面的从句以than引导,是比较状语从句,所以应选择副词比较级。A和B分别是形容词原级、比较级,应排除。C是副词的原级,也应排除,因此,只有D才是正确答案。 ◎Does your brother remember ____ a talk to us last month? A. give B. giving C. to give D. given 【分析】动词remember后不可接动词原形和过去分词,因此A和D可首先排除。虽然remember后可接动词不定式或动名词,但意思有区别,接动词不定式是表示“记住做某事(实际还未做)”,接动名词则表示“记得做过某事(实际上已经做了)”。从该句句意来看C也可排除。自然,剩下的B就是正确答案。 2. 比较法 运用所学的语法知识,仔细地比较四个答案,对其进行时态、语态、语气、非谓语形式及同义词比较,最后选出正确答案。较难的选择填空题一般都可以采用这种方法。 ◎His grandfather ____ for ten years. A. died B. was dead C. has been dead D. has died 【分析】“died”和“was dead”都是一般过去时,因“for ten years”是表示延续时间的状语,谓语时态要用现在完成时,所以选A或B都不行。“has been d ead”和“has died”虽然都是现在完成时,但因“die”是终止性动词,且在有for…或since…的句中,就必须选用延续性动词be。这样,正确答案应该选C。 ◎You will not go there,I’ll go ________. A. neither B. too C. either D. also 【分析】所给答案的四个单词是同义词和反义词,要通过比较它们的用法才能最后选出正确答案。also用在行为动词前,选D不行。其他三个虽然用在句末,但B和C都与句意不符。因此,只有A才是正确答案。 3. 逻辑推理法 有些用词从语法上看并没有错,但句意不合逻辑。因此,做此类题时,就需要根据逻辑推理来选出正确答案。例如:
