是测验的题目哦?怎么会那么tricky?
我们这三年级的数英统一试就有这样的题目 : ( )-4897=7940-2135

上次在新山上了南院的数理教学法时,我拿了份考卷(四年级科学)问中国来的教授:
粪便是不是人体的排泄物?
他说是,严格来说粪便排出体外时,夹杂了部分的身死细胞。这不是身体的排泄物吗?
(但课本里说,粪便是身体所排泄的渣滓,不是排泄物)
唉,难啦。。。
他顺带的看了看其他的问题,惊讶的说马来西亚的考卷太难了,根本就是为考到学生而设的。哈哈。。。

惠欣、慧婷,谢谢你们提供这么精彩的题目。
是的,我们的老师出题往往像似要难倒学生才罢休,而且很多时候特别爱往牛角尖里钻。像以前的什么一个句子是否可以有两个标点符号呀之类的。不但将死自己,也害苦别人。

This must be based on the concepts we use in English.

Defaecation (as part of the digestive system) is excreting undigested material + bacteria as faeces. However, most of the faeces is not waste product of metabolism with exception of bilirubin which is breakdown product of RBCs, excreted in bile by liver.

Excretory/Urinary system on the other hand is excreting nitrogenous wastes from the body as we perform our various metabolic processes, protein and nucleic acid, both of which contain nitrogen, are broken down. Some of the nitrogen is recycled to build new nitrogen-containing molecules but much of it cannot be used for this purpose and must be disposed of as waste.
