当主语为第三人称单数时，一般现在时的动词有所变化。 ❶一般情况在动词后+s 如；work—works He works hard . ❷动词以 s s，x, sh , ch ，o 结尾的，词尾+ es
always 总是 usually 通常 often 经常 sometimes 有时 hardly ever 几乎不 never 从来不
always 总是 .是发生频率最高的那个词，发生频率为 100%或者将近100%.
usually，often，sometimes，它们的汉语意思分别是： 通常 经常 有时 看三者有什么样的关系？或者你觉得有什么变化？
hardly ever 几乎不 。但还是有些可能.
never 从来不，它的发生几率几乎为零.
按照频率的高低，可以看到这样的排列 顺序：
always ∧ usually ∧ often ∧ sometimes ∧ hardly ever ∧ never
总是
∧ 通常
∧ 经常
∧ 有时
∧ 几乎不
∧ 从来不
