A qualified to B.is qualified to C.is qualified and D.is qualified for
if you have a job,________ yourself to it and finally you'll succee.
A.do devote B.devoting

答案

第一题选D,此处content为形容词“满意的”,用作伴随状语.A、B项对应的正确形式应是satisfied,C项不应加“-ed”.
第二题选D,“be qualified for”意为“有资格做某事”.
第三题选A,“do+动词原形”结构表强调,本质是完整的强调句,充当if条件句的的主句；B项形式是非谓语动词,无法构成句子,故不选.
