【正确答案】
B
【答案解析】[解析] 本题考查短语的用法。本题句意为:教师不能想当然地认为学生都会按 照要求做家庭作业。as follows表示“如下”,后接事例;as required表 示“如所要求的那样”,required前省略了they are。
[知识点] as的用法。as可以用作连词,表示“依照,像…一样”,例如:Do as you are told.照我说的去做。The work is not so difficult as you imagined.这工作不如你想象的那么难:as可以用作代词,指代前面(或 后面)所出现过的事物。例如:As is known to all,the earth is running round the sun.众所周知,地球围绕太阳转。We are tired, as everyone can see.我们累了,这是有目共睹的。as follows是个固定搭配的短 语,后接具体事例,如:The results are as follows.结果如下。
