问题 They will not start the project until the board chairman ______ back from South Africa.
选项 A、will come
B、is coming
C、came
D、comes
答案 D
解析 本题考查从句时态用法。在not...until...结构中，当主句用一般将来时，until引导的从句，用一般现在时。所以D项为正确答案。在由if, unless，supposing，as long as，in case，when，until等词语引导真实条件句或时间状语从句中，主句往往是一般将来时或祈使句，从句要用一般现在时表示将来的情况。【例句】：(1)You’ll be late for class if you don’t hurry．(如果你不赶紧，上课就要迟到了。)   (2)We will find a way to overcome the difficulty，as long as we don’t lose heart．(只要我们不灰心，我们就能找到克服困难的办法。)
