fall - ill的延續性動詞形式是什麼

fall ill相對應的延續性動詞是be ill。

fall ill是瞬間性動詞，不可以延續，所以不能和since短語連用。

如：Be careful not to fall ill．注意不要生病了。It is easy for the old to fall ill in winter.老年人很容易在冬天生病

be ill是延續性狀態，所以可以跟since連用。

比如：She has been ill since she came home from the rain at the seaside yesterday。自從昨天在海邊淋雨之後，回家她就生病了。

She doesn't want to eat anything because she has been ill for a while。因為她這段時間生病了，所以什麼東西都不想吃。
