1 what's today's special?
perhaps i_______ suggest mushroomsoup and clearsoup.
a must b might c would d could
为什么选d,d项could 从语气上>might<must.怎么翻译:"我会推荐", 如选might或would,前者不真诚, 或者有太主观, could 可以表示可能性;
2 the exercise is not_______ difficult but just needs care and patience.
a by itself独自地, b of itself自动地 c in itself本身 d for itself

3 if we go on using energy so wastefully,_________are our oil wells will be dried up before new energy sources can be found to replace oil.
a chances b difficulties c questions d problems

4 在阅读理解中有这么一句话如何翻译？chance"可能性"
