每句有一个错，请哪位给详细讲解一下
It is interested to visit another country， but sometimes 51． ＿＿＿ there are some questions when we don’t know the language very 52． ＿＿＿ well． It may be difficult to talk about the people there．We may 53． ＿＿＿ not know how to use the telephone in the country which are 54． ＿＿＿ visiting． We may not know what to buy the things we need． 55． ＿＿＿ In a strange country we may not know where to eat and what 56． ＿＿＿ to order in a restaurant． It is not easy to decide how many 57．＿＿＿ money to tip（付小费） waiters or taxi drivers． When we are 58． ＿＿＿ helpless， we may not know how to ask help． 59． ＿＿＿ After a short time later， however， we learn what to do 60． ＿＿＿ and what to say． We learn to enjoy life in another country， and then we may be sorry to leave both the place and the people．
51。interesting【这里是it作形式主语 动词不定式是真正主语即to visit another country 而这件事应用interesting修饰】 52。there will be【when引导的时间状语从句 从句用一般现在时 主句就用一般将来时 （即主将从现）】 53。
Maybe it is【连着的maybe表猜测，放于句首 而分开的may be意为“可能是”放于句中，此处根据句意得出应用maybe表猜测】 54。countrys 【后边用的are】 55。how to buy【根据句意得】【如果用what就做了buy的宾语 就不能再有the things。
。。了】 56。how to order【根据句意啊】 57。how much【money不可数 】 58。ask for help【ask不能直接加宾语】 59。去掉“after”或“later”【重复了】 60。learnt 【根据“After a short time”或“a short time later”应用过去时】。
