题目内容
We’ll climb the mountain _______ the weather is bad this weekend.
| A．if | B．when | C．until | D．unless |
D
解析试题分析：句意：我们将会爬山,除非这个周末天气不好。IF是如果的意思，如果结果是肯定的那么IF后面引导的从句（从句在主句前面用逗号隔开）用一般现在时，而主句也用一般现在时。如果结果是可能的主句（从句用一般现在时）就用一般将来时。UNLESS相当于IF NOT就是如果不/除非的意思用法和刚才IF用的一样。总结：结果是肯定的就主现（在时）从现（在时）结果是可能的就是主将从现啦。无论结果是肯定的或可能的从句都是一般现在时而变化的是主句！故选D
考点：考查连词的用法。
