More praise to yourself, you’ll build up confidence throughout the difficult times.A. but

网友回答

A. but
(答案→)B. and
C. or
D. however
解析：考查特殊句式。本题中含有特殊句式：祈使句+连词+陈述句=If引导的条件句+主句。这个句型进一步转换成：名词短语+连词+陈述句。本题中使用了“名词短语+连词+陈述句”本句=If you praise yourself more, you’ll build up confidence throughout the difficult times.后面构成的是肯定的陈述句，故B正确。
