可以的呀,举些例子。
Jessie only tried that problem one time and she was able to get the right answer。 Tom, on the other hand, was not able to get the right answer even after trying the same problem over ten times。
two times/twice都可以,没啥规矩
twice英国更流行,two times美国更流行
放在动词前面一般用twice,如he has twice broken the rules比two times broken更顺当,虽然后者也是正确的。
thrice是很古老的说法了,现在一般都是three times.
