1.—Do you know whether Mary will go there?
—I'm not sure.She says she will stay at home unless she
________ to the party为什么是:(was invited).
2.—Did you see Tom at the party?
—No,he ________ by the time I got there.为什么是:(had left).
这两句话考察的都是对时态的把握.
第一题:首先要弄明白包含横线的这句话什么意思.
翻译成汉语就是:她说她会待在家里,除非她已被邀请去派对.
其次,要弄清句子的时间关系.
该句中的主句用的一般现在时态,后面的will可以看成是一个情态动词;
unless后面的从句强调的是一个过去应该发生的动作,当然这个动作并未实际发生.
第二题:首先应判断出句子用过去时态,
其次,根据by the time判断出是完成体,
所以,had left是正确选择.
