1、choice可数还是不可数:
choice作为“选择机会”“选择能力”“选择权”等意思讲的时候是不可数名词,作为“选择某人”“选择某物”“选择某职位”等意思讲的时候是可数名词。所以choice的可数与不可数决定于跟随的是实物名词还是虚名词。
2、在 have no choice but这一结构中,其后通常要接带to的不定式,表示“除了做…以外,别无选择”或“只好做…”:
I had no choice but to wait. 除了等,我没有别的选择。
I had no choice but to cancel my holiday. 我只能取消假期,别无选择。
He had no choice but to accept (= He had to accept). 他别无选择只能接受。
He will have no choice but to ally himself with the new movement. 他将别无选择,只能与这个新运动结盟。

3、表示在某范围内选择时,以下几点需注意(注意搭配):
(1) 在两者之间选择(注意 between 的使用):
He has to make a choice between the two books. 他得在这两本书中选择一本。
You must make [have] a choice between this and that. = You must make [have] the choice of this or that. 这样东西和那样东西你必须选择其一。
上面最后一组句子的结构不能混淆,如不能说:
You must make [have] a choice of this or that.
(2) 在三者或三者之上选择(注意 among 的使用):
Beer is the drink of choice among sportsfans. 啤酒是受体育爱好者喜爱的饮品。
She was asked to make a choice among the three. 她被要求在这三者当中选择一个。
(3) 在不明确范围选择:
They have no choice left. 他们别无选择。
What’s your choice? 你选哪个?
