1. As your instructor advised, you ought to spend your time on something researching into.
[A] precious [B] worth [C] worthy [D] valuable
1.[考点] 形容词辨析
[分析]本句中不定代词something后接形容词短语作后置定语,因此空格处填入的形容词应接动名词结构researching into。[A]和[D]项都不能接动名词,首先排除。precious意为“珍奇的,珍贵的”,valuable意为“有价值的,宝贵的”。worth和worthy都可意为“值得的”,但使用上有区别。worth作表语时,后常接名词或动名词,如:be worth considering/the trouble(值得考虑/值得费那个事);worthy后一般接不定式或of sth.,不可直接接动名词,如:be worthy of consideration/of praising/to be remembered(值得考虑/值得奖励/应该谨记的)。因此[B]项正确。
[句意] 正如你的导师所建议的那样,你应把时间花在值得研究的问题上。
