D．should

Answer 1

B

解析試題分析：句意：“乘客不得在輕軌上吃早餐。”這個(gè)規(guī)定在重慶引起了熱烈的爭(zhēng)論。shall在陳述句表示說話者的允諾、告誡、威脅、命令、規(guī)定、必然性等，主要用于第二、三人稱。如：
1. You shall have a sweet. 你會(huì)吃到一塊糖。(表允諾)2. You shall do as you please. 你可以隨意行事。(表允諾)3. He shall suffer for this. 他將為此受苦。(威脅)4. Each competitor shall wear a number. 每個(gè)參賽者要戴一個(gè)號(hào)碼。(表規(guī)定)，解題關(guān)鍵詞：rule. 故B正確。
考點(diǎn)：考查情態(tài)動(dòng)詞的用法。
