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
举一反三
