—I ________ speak English in class because I’m afraid of making mistakes.
—Don’t be shy. Believe in yourself and everything will be OK.
A.needn’t B.dare notC.dare not toD.needn’t to

答案
B  
解析

试题分析:英语中need和dare都可以作为情态动词和实意动词使用。 need作情态动词无人称或数的变化, 后接动词原形,多用于否定句和疑问句中;need 作为行为动词有人称和数的变化, 后面可接名词、代词、动名词及带to 的动词不定式;可用于肯定句、疑问句和否定句中;dare用作情态动词,后跟动词原形,主要用于疑问句、否定句和条件句中;dare用作实义动词,此时其后的动词不定式可带to也可不带to,且dare有人称和数以及时态的变化。句意:我不敢在课堂上说英语,因为我害怕犯错误。结合语境可知本句中描述的是自己的情感态度,故dare用作情态动词,选B。
