試題分析：考查不定式的用法：句意：可憐的男孩似乎不知道他父親去世的消息，因?yàn)樵谒�的臉上看不見悲傷的表情。Seem后面接不定式做賓語，seem to do似乎要做…，seem to be doing似乎正在做…，seem to have done似乎已經(jīng)做…，否定詞not放在to前面，根據(jù)句意選B.
點(diǎn)評(píng)：動(dòng)詞agree, choose, decide, hope, fail, wish, refuse, expect, manage, plan, intend, pretend, promise, offer, seem，afford, demand和arrange后面一般接不定式，不定式還有三種形式：一般式to do，進(jìn)行時(shí)to be doing，完成式to have done，要結(jié)合句意來辨別。
