一、单句填空 1.(2015·江苏高考改编)Many wastes produced in the producing process are (harm) as well. 1.harmful。空格前是be动词,可知此处作表语,故用形容词。 2.(2015·四川高考改编)People have long puzzled how the Egyptians moved such huge rocks. 2.over。puzzle over 是固定搭配,意为“冥思苦想”。 3.He’s argued that America and its allies are putting too much(emphasize) on the military option. 3.emphasis。put emphasis on...为固定搭配,意为“把重点放在……”。
4.(2017·山东高考改编)Susan made clear to me that she wished to make a new life for herself. 4.it。句意:苏珊清楚地向我表明她希望为自己创造新的生活。分析句子结构可以看出,该句中包含一个that引导的从句,而且根据语境可知,that从句的内容就是苏珊向我表明的事情,所以后置的that从句实际上是made的真正宾语,故用形式宾语it指代that从句。 5.(2017·陕西高考改编)The manager wants to see changes in the company,and I am sure he will time. 5.in。句意:经理想要看到公司的改变,我确信他迟早会看到的。in time“及时;最后,迟早”,符合题意。 6.(2017·福建高考改编)Old-fashioned phones matter when wireless networks break ______in disasters. 6.down。句意:在灾难中,当无线网络出故障时,老式的电话意义重大。break down“停止转动,出故障”。
7.(2017·上海高考改编)—Was it by cutting down staff she saved the firm? —No,it was by improving work efficiency. 7.that。题干是强调句型的一般疑问式“Is/Was+it+被强调部分+that/who+其他”。句子强调的是方式状语by cutting down staff,用that构成强调句型的基本框架。 8.(2017·江西高考改编)We needn’t have bought so much food now Suzie won’t be with us for dinner. 8.that。句意:既然苏姿不和我们一起吃晚饭,那我们就没有必要买这么多食物。now that是固定搭配,意为“既然”,强调已知原因。 9.(2017·湖北高考改编)Whether the buildings in this area should be pulled has remained controversial;people are still looking for other possible solutions. 9.down。句意:这个地区的建筑是否应该被拆毁仍有争议;人们还在寻找其他可能的解决方案。pull down为固定短语,意为“拆毁”。
10.(2011·广东高考改编)Often,we try every way possible to avoid showing our________(weak),which includes a lot of pretending. 10.weakness。空处有our修饰,故应填名词weakness“弱点”。
