第二题的标准答案是passers-by用的是哪个知识点啊？还有第三题为啥不在somebody后面加`S啊

答案

1.B这里的scissors 是剪刀的意思,一般要用复数类似的有trousers,glasses,gloves等,a pair of 是一副的意思,如果说两把剪刀应该说成two pairs of scissors.
3.B 如果说用somebody's 的话意思就是某人的,这里是想表达其他的某个人.没有somebody's else 这种用法,如果题目中用成he said he want to know somebody's opinion.在语法上也没有错误.
4.C其他的work也是工作的意思,但是不可数,这里有a teaching++应该选可数的post 意思是岗位,职位.career 是事业,employment 雇佣.
