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
