46.【答案】C。 解析:A选项hope表示“希望”,常用hope to do sth.但是注意hope后不能接sb. to do sth.。B选项wait常构成词组wait for...to do sth.表示“等待……做……”,强调“等”的含义,C选项expect表示期望,盼望,表示认为有很大的客观可能性;D选项imagine表示想象、设想。本题意为“我们不能期望一个人如此短的时间内改变一辈子养成的习惯”,因此答案选C。
47.【答案】B。解析:hundred一词前面有具体数词修饰时不加-s,且people单复数同形。故选B。
48.【答案】D。解析:考查主语从句, It为形式主语,that引导的从句为真正的主语。句型It occurs to sb. that...“某人突然想到。”因此D为正确答案。
49.【答案】B。解析:考查宾语从句, 宾语从句的语序是陈述句语序,所以AC先排除,B的意思是通过读这篇文章,我们知道在我们的日常生活中可以如何减少污染,D选项的意思是我们必须循环利用东西,与空前“how如何”连用不通顺。根据句意的通顺来判断,B为正确答案。
50.【答案】B。解析:考查表语从句,句意:纸厂就是纸被制造的地方,系动词后为表语,所以此处is后面是表语从句,在从句中不缺少成分,所以可以加上状语,D选项不能引导表语从句,which和what作主语、宾语、表语,不作状语,where做状语,故B为正确答案。
