B

shall ---- 一般是 I shall ... 比较固定

又如：

1, Amount of equity invested by each partner.

2, Type of business.

3, How profits and loss will be shared.

但是答案是A也

追答

不知你能不能看到这个连接：asq.org/standards-shall-should

看了给你的这个连接的内容，我才知道，

shall可以“denotes a requirement that is
mandatory whenever the criterion for conformance with the specification
requires that there be no deviation”

should 可以“denotes a guideline or recommendation whenever noncompliance with the specification is permissible.”

我也学习了。

追问

额·······能帮忙翻译下么·········

Answer 2

B。 在公告或条例中出于礼貌，常用should. may表示“可能”，can表示有能力做，shall有威胁、命令的含义，在一、三人称中表示请求。

Answer 3

还是选择B吧
