答案

i could not find any likely place＿to fish﹝fish﹞nera there 动词不定式做定语,钓鱼的地方
how long does it take you _to walk﹝walk﹞50 meters?这是句型 It takes sb.some time to do sth
that chair takes up too much＿room﹝room﹞ room 这里是 空间,地方的意思,不可数名词
someing serious is ＿happening﹝happen﹞to me happen 是不及物动词,没有被动,前面有is,因此填doing,现在进行时
their mother started to get＿worried 〔worry〕when they didnt arrive home get是系动词,后面加形容词worried
