1.The next thing he saw was smoke ________ from behind the house.
A. rose B. rising
C. to rise D. risen
[解析]句意：随后，他看见烟从房子后面冒出来。本题考查非谓语动词作定语，修饰 smoke，故排除A项(谓语动词);逻辑主语 smoke 与非谓语动词间为主动关系，而且动作正在进行，故答案为B项。
[答案]B
2.The island, ________ to the mainland by a bridge, is easy to go to.
A. joining B. to join
C. joined D. having joined
[解析]句意：这个岛由一座桥和大陆连着，很容易去的。island 和 join 之间是被动关系，故需用过去分词。joined to the mainland by a bridge 相当于一个定语从句 which is joined to the mainland by a bridge。
[答案]C
3.Sarah pretended to be cheerful, ________ nothing about the argument.
A. says B. said
C. to say D. saying
[解析]句意：Sarah 假装很高兴，没有对这次争论进行评论。分析句子结构得知，此处是分词作伴随状语，故排除A项谓语动词的形式;say 与逻辑主语 Sarah 之间是主动关系，排除表被动的B项;动词不定式作状语通常表目的或出乎意料的结果，故C项与语境不符。故选D。
[答案]D
4.Look over there—there's a very long, winding path ________ up to the house.
A. leading B. leads
C. led D. to lead
[解析]句意：往那看——有一条很长很曲折的小路通向那所房子。现在分词短语在此作后置定语，相当于定语从句 which leads up to the house。leads 在句中作谓语;led 是 lead 的过去分词形式，与 path 构成被动关系;to lead 表示将来，均不符合句意。
[答案]A
5.Passengers are permitted ________ only one piece of hand luggage onto the plane.
A. to carry B. carrying

[答案]A
6.________ into English, the sentence was found to have an entirely different word order.
A. Translating B. Translated
C. To translate D. Having translated
[解析]句意：被译成英语后，我们发现这个句子有了一个完全不同的语序。分词作状语时，其逻辑主语应和句子主语保持一致，本句中的主语 the sentence 与 translate 间为逻辑上的被动关系，故排除A、C、D三项，只有B项表示被动，故为答案。
[答案]B
7.On receiving a phone call from his wife______ she had a fall, Mr Gordon immediately rushed home from his office.
A. says B. said
C. saying D. to say
[解析]句意：一接到妻子的电话，说她摔了一跤，戈登先生立即从他的办公室跑回家了。say 与 phone call 之间存在逻辑上的主谓关系，故用 saying 作定语。say：give information or instructions 表示(书、符号等)给出某信息或指示，又如：The book doesn't say where he was born.书上没说他是在哪里出生的。
[答案]C
8.Claire had her luggage ________ an hour before her plane left.
A. check B. checking
C. to check D. checked

A. making B. made
C. to make D. having made
[解析]句意：中国又建了很多公路，这使得人们出行变得更加容易了。空格处非谓语动词逻辑上的主语是逗号前面的内容，和非谓语动词之间是主动关系，可排除B项;C项为动词不定式，通常表示目的，表出乎意料的结果时前面通常加 only 或 never，所以排除C项;make 表达的动作并非发生在谓语动词动作之前，不用完成形式，故排除D，选A，making it much easier for people to travel...=which makes it much easier for people to travel...
[答案]A

A. to keep B. keeping
C. having kept D. to have kept
[解析]句意：坐下，Emma。站着只会让你更加劳累。逻辑主语 you 与 keep 之间为主动关系，所以选择B项，现在分词作伴随状语。A、D两项为不定式，通常表示目的，所以排除;C项为现在分词的完成式，不表示伴随，故排除。
[答案]B
12.Tsinghua University, ________ in 1911, is home to a great number of outstanding figures.
A. found B. founding
C. founded D. to be founded
[解析]句意：清华大学，创办于1911年，是许多杰出人物的母校。首先排除 found，因为 found 作“创办”讲时，为动词原形，不是非谓语动词;被修饰词 Tsinghua University 与 found (创办)为被动关系，故排除B项;C项表被动且完成;D项表将来。根据题意可知C项为正确答案。founded in 1911在句中相当于非限制性定语从句 which was founded in 1911。
[答案]C
