句意：通常北京烤鸭配上特制的薄煎饼、青葱和甜酱。
句子说的是一般情况，要用一般现在时态；句子主语Beijing Roast Duck是单数第三人称，和谓语动词serve之间是被动关系，所以推知句子要用一般现在时态的被动语态，故答案为C。
9．The old man was weak after the accident; so he ______ carefully by us.A．must be take care of B．must take care ofC．must look after D．must be looked after【答案】D【解析】【详解】考查含情态动词的被动语态。
句意：事故发生后，老人很虚弱；所以他必须由我们仔细照顾。
固定词组：take care of/ looked after“照顾”；句子主语he和谓语动词之间是被动关系，所以这里是含情态动词的被动语态，“情态动词+be +过去分词”。
故选D。
10．Various efforts ________ in the past decades to protect the environment.A．had made B．have madeC．were made D．have been made【答案】D【解析】考查时态和语态。
句意：在过去的几十年里，为保护环境做出了各种努力。
根据in the past decades可知句子用现在完成时态，efforts是句子主语，复数形式，和谓语动词make之间是被动关系，所以此处用现在完成时态的被动语态，故答案为D。
11． in a red dress, she was easy to in the big crowd at the airport.A．Being dressed; pick out B．Dressed; pick outC．Dressed; be picked out D．Having dressed; pick out【答案】B【解析】【详解】考查过去分词和动词短语。
句意：因为她穿着红色的裙子，所以在机场的人群中很容易被认出来。
be dressed in穿着……，作状语表状态，故用dressed。
sb be easy to do sth主动形式表达被动意思，所以用pick out。
故B选项正确。
【点睛】主动形式表被动意义的不定式1.主语＋be +adj. +to do。
能用于此句型的形容词有: difficult, easy, comfortable, fit, hard, pleasant, tiresome(使人疲劳的), interesting, nice, heavy, dangerous, light, important, etc.注意：当上述形容词在句中作宾语补足语，后接不定式时，不定式也用主动形式表达被动含义。
2.主语+be +adj. + enough +to do。
3.主语+be +too +adj. +to do。
4.不定式短语作后置定语时，如果主语是不定式动词短语的逻辑主语。
则采用不定式的主动形式表被动概念。
I have a meeting to attend today.5.There be 句型中，用来修饰主语的不定式多用主动。
6.在“疑问代词 + 不定式”结构中。
7.let, to blame, to seek等用不定主动形式表示被动含义。
8. with+O.+to do 结构中，不定式作宾补时，常用主动表被动，且表将要发生的动作。
分析句子可知，sb be easy to do sth主动形式表达被动含义，符合第一点用法。
所以用pick out。
故B选项正确12．—I wonder why Robert hasn’t shown up at the interview yet. It’s a pity if he missed—I’m not sure, but he _______ in a traffic jam riding here.A．could stuck B．should stuckC．must have stuck D．might have been stuck【答案】D【解析】考查含情态动词的被动语态。
上句：我想知道为什么罗伯特面试还没有出现。
如果他错过了很可惜。
下句：我不确定，但是他可能被困于交通堵塞。
此处表示对过去已经发生事情的推测应该用情态动词的完成式，根据句意可知是被动，故答案为D。
