He is really______great success on business 问为 么这里为什么要用a来修饰s she's had to go to chicago on a business trip中she后面为什么用is ha A good beginning is half of success 这里的 begin 为什么 要加ing He is on whom a responsibility falls. 为什么这里on到了wh he thinks it is the key to his great success .success用不用加s, He is a boy 这里的a boy是不是表语吖 其中a 修饰boy He is not here,He _____ aboard on business A.has been B.has maybe he should say he's sorry.这里为什么要用 he's?可以用his 代替么? 英语“My success is based on persistence,not luck”为什么base要用过去式? What a lot of trouble he is causing 这里的 trouble 为什么不是复数 加 S what a great success your meeting is?这句话什么意思?为什么success会被译为成 He is sure____his success.A.at B.of C.in D.on
