These boxes should be examine carefully and graded _____ size.
请问应填介词 in 还是 by?by size与in size的用法有何区别?谢谢!
陈老师:
▲最佳答案应该是 by。by 在此表示依据,意思是“根据”“依据”。by size 意思是“按大小”“按尺寸”等。又如:
The containers are graded by size. 容器按尺寸分类。
The fruit is washed and then graded by size. 水果洗净后按大小分等级。
▲in size 的意思是“在大小方面”。如:
Those shoes are just right in size. 那鞋大小正合适。
They differ in size but not in kind. 它们大小不一但本质相同。
It’s smaller in size but greater in weight. 它体积比较小,但分量比较重。
The models differ in size and shape. 模型的大小和形状都不一样。
The two towns are very much alike in size and population. 这两个城镇在规模和人口方面都十分相似。
黄老师:
赞同,顺带指出是,这句话应该是被动语态,examine 存在拼写错误,应该改为 examined。全句的意思是:对这些箱子应该仔细检查,并按尺寸归类。
