1 work当工作讲时不可数,但当翻译为著作或者作品时为可数名词,本句有one of 后面需要加可数名词复数,后半句是说这是一项很难的工作,因此是不可数的.
8首先是词组have difficulty in doing做某事有困难,difficulty困难不可数名词.还有要说一下some它可以修饰可数名词也可以修饰不可数名词都表示一些.
9答案是D这道题很让人迷惑.其实我认为用那个形式都对但硬要区分一下这就要说一下effort这个单词当它指做某事的精力和力量时是不可数名词,make the effort to do翻译为努力做,但当指努力奋斗时是可数名词也有句型make an effort to do努力做,本句中虽然翻译为老师努力劝同学但可以看出老师是浪费精力努力劝服学生因此只能选effort不可数名词.第二个空词组have an effect on对什么有影响同样也要放在句中看,因为句子是说媒体和社会环境对他们的选择有影响因此可想像出影响是多方面的也是很多的,因此这里的effect要用复数.顺便说一下,四选一这种题在英语中叫做choose the best answer,选择最好最合适的答案,因此选择是要注意选择最合适句子的答案.
