鼎力相助 do whatever one can to help
刮目相看 look at sb with new eyes
百听不厌 be worth listening to a hundred times
欣喜若狂 be wild with joy
不辞而别 take leave without saying goodbye
兴趣相投 share the same hobby
宁死不屈 would rather die than give in
反之亦然 vice versa
不知所措 be at a loss to do
坚守岗位 stick to one's post
坚持不懈 perserve in doing
半途而废 give up half way
一事无成 achieve nothing
梦想成真 one's fream come true/realize one's dream
一无所有 have nothing
一无所获 gain nothing
一鸣惊人 surprise the world with one's first success
不辞辛劳 take trouble to do/take pains to do
跋山涉水 travel over mountain and waters
不遗余力 spare no efforts
不能自己 can't control oneself
一见钟情 fall in love with....at first sight
受益匪浅 benefit a lot from
爱莫能助 be powerless to do
