2019年mba考试英语模拟题——连词706

{01}—How can I wake up that early?
—Set the alarm at 3 o’clock, ________ you’ll make it. A.but B.or C.and D.so 解析：      题意：------我怎么能起得那么早？------把闹钟调到三点，你就会起来了。考查“祈使句+and+陈述句”句型，意为“如果…就…”。虽然or也可用于此句型，但or是“否则、要不然”之意，如：Work hard, or you’ll fail. (努力学习，否则就会不及格。)
本题选C。
{02}It has been proved______eating vegetables in childhood helps to protect you against serious illnesses in later life. A.if B.because C.when D.that 解析：此题考查that引导的主语从句的用法。句中的it是形式主语，真正的主语是eating vegetables in …life,所以要that引导这个主语从句，而that不作任何成分，也没有意义，故答案是D项。
本题选D。
